    1 DEVICE FOR SINGULATION OF GRANULES, AGRICULTURAL EQUIPMENT INCLUDING SUCH DEVICE AND PROCEDURE FOR SINGULATION OF GRANULES Technical field This document relates to a singulation device for singulation of granules, as exposed, fertilizers or pesticides. The document further relates to an agricultural implement comprising such a singulation device and a method for feeding granules.
    Background When sowing with the help of a co-machine, it is desirable to achieve an optimal distribution of the exposed: available area should be used as much as possible, but the crop must not be planted too quickly, as the yield can then be reduced.
    In a common type of co-machine, distribution of the exposed takes place in a distributor which is connected to a salad. The distributor can either be connected directly to the lower part of the salad or via a pipe leading to a distributor head, the distributed seed, with the aid of an air flow, being led in pipes or hoses to the respective This type of distributor is stalled as a shelf to feed out a certain amount (expressed in weight) of granular per unit area. It has been found that when the granules are distributed with known distributors, a distribution is obtained which is acceptable, given the cost and complexity of the equipment used. However, it is necessary to further improve the precision when feeding exposed and other granular material, so that the distribution of the exposed becomes as optimal as possible. This is for all optimization of the amount of exposure per 25 area unit Okar vane plant's potential to give a high return as a result of it having optimal access to water, space, light and nutrients.
    Set to achieve such precision improvement is shown in SE520798C2 and SE524649C2. However, there remains a need for a device capable of improving the precision of feeding exposed, which is robust, flexible and not too expensive to manufacture. DartiII yore det Onskvart am the 2 provided device can easily be integrated with existing machine constructions and the yarns can also be retrofitted to older machines.
    SUMMARY An object is thus to provide a singulation device and a singulation method which can be used to improve the precision when sowing or distributing granular material.
    The invention is defined by the appended independent claims and embodiments appear from the independent claims, the following description and the accompanying drawings.
    According to a first aspect, a device is provided for singulating granules, such as exposed, fertilizing or pesticides. The singulation device comprises a singulation disc which has a plurality of continuous slides. The shark is adapted in shape and size to receive individual granules and the shape and size of the shark are such that the granules can only pass one at a time through each hall.
    This limits the amount of exposed material that can pass through the singulation device.
    The shape and size of the flange may be such that the granules are loosely retained therein.
    The shark may be arranged along a circumferential direction of the singling disc.
    The shark may be arranged in at least two rows along the circumferential direction of the singling disc.
    The shark can be substantially uniform and have a greater length in the circumferential direction than a Mien intermediate portion of the singulation disk.
    The shark can have a cross-sectional area in a material flow direction.
    With Okande cross-sectional area, a slack angle can be achieved, which reduces the risk of granules or scrapes getting stuck in the tail.
    The board may have at least a hall with a larger cross-sectional area than the other hall, wherein said cross-sectional area may three times be 120-350% of the other ha's cross-sectional area, preferably 150-300% larger or about 200-250% larger. By providing the singulation disc with one or more such hatches with a larger cross-sectional area, it can also let through granules which are too large for other hatreds, whereby the risk of the singulation device being filled up with too large granules is reduced.
    A number of holes with a larger cross-sectional area may be less than 5% of the total number of holes of the disc, preferably less than 3% or less than 1%.
    The singulation disk may have between the Mien coated material portions which exhibit protrusions which prevent granules from remaining between the Mien.
    The device may comprise orientation means for ensuring proper mounting of the singulation disc in the device.
    Such orienting means may comprise a recess and a projection fitting in the recess, one of which is arranged in the singulation disc and the other is arranged on a drive hub.
    The singulation disk can be flexible so that, during operation, it can be bent in a direction substantially perpendicular to the disk to facilitate passage or release of granules received in the mine.
    The singulation disc may be flexible substantially in the direction parallel to the singulation disc to facilitate passage or release of granules received in the tail.
    The device may comprise a hut, in which the singulation disc is arranged. The 1-161 jet may comprise an inlet for granulating air and an outlet for granulating air. The inlet and the outlet may be located on opposite sides of the singulation disc and substantially aligned with each other.
    The device may comprise a granular bypass duct, arranged to provide a granular mixed air duct directly from the inlet to the outlet, and thereby completely or partially bypass the singulating device.
    The cover may have a bottom portion, wherein the singulating disc may be placed sufficiently near the bottom portion so that the ht of the disc, together with the bottom portion, forms a bottom hall. The bottom part may have a gap running in the circumferential direction, which coincides radially with at least a part of the Mien so that air, but not granules, can pass through said bottom hall.
    This provides improved retention of the granules in the Mien by pressing or sucking the granules into the tail.
    The singulation disc may have at least one projection, which protrudes into the gap. Thus, a self-cleaning effect can be achieved.
    The device may comprise an air collecting housing, which may be designed to collect air which passes through the holes in the singulation disc, and through any spatters in the lower part of the housing. The air collection housing can be designed to lead collected air to the outlet or to a separate duct which opens closer to the ground than the outlet. For example, the collected air can be led to a channel integrated with a beetle so that outgoing air is led through the beetle into the ground and thereby contributes to entraining granules emanating from the singling device. Alternatively, the collected air can be led in a separate duct which opens closer to the ground than the singulation device.
    The device may comprise an air bypass duct, arranged to provide only one air surface directly from the inlet to the outlet, and thereby partially bypass the singulation device.
    Thus, some of the air can be led past the singulation device, which can be used to reduce the turbulence in the singulation device.
    Device may comprise pressure means arranged to push the granules through the Mien.
    Such pressure means can be particularly advantageous when the singulation disc is designed to loosely grind the granules.
    Pressure means may comprise a biased arm against the singulation disc. Pressure means may comprise projections, shaped to be at least partially received in the singulation disc. The projections may be in the form of axes, bristles or spikes.
    Pressure means may have an abutment portion, for abutment against the singulation disc, which is sufficiently flexible to be pressed into the h61 of the disc.
    Pressure means may comprise after wheels, the periphery of which abuts or engages with the singulation disc slippery.
    The wheel may have projections or axles, which engage with the slider of the disc.
    Alternatively, the periphery of the wheel may be provided with a flexible abutment portion. It is also understood that a wheel can be biased against the disc in another way by means of an arm, for example by the axle of the wheel being biased movable in a direction substantially perpendicular to the disc.
    The device may comprise a drive unit, arranged by directly or indirectly set the singling disc in motion.
    The drive unit can be arranged to cause the singling disc to rotate.
    Alternatively, the drive unit may be arranged to cause a drive wheel to rotate, and the drive wheel may be arranged to engage the singling disc and thereby cause it to rotate.
    The drive wheel can be integrated with eft pressure means.
    For example, the drive wheel may be provided with a plurality of teeth, which engage with corresponding teeth arranged on the disc. Alternatively, the drive can be effected by causing a pressure wheel, which may be provided with projections, to rotate and the engagement of the projections with the disc causes the latter to rotate.
    The drive unit may comprise a motor, which may be axially retracted towards or through the singulation disc.
    Thus, a more compact singulation device can be provided. The device may comprise agitating means, shaped to provide a shaking motion between the singulation disc and the granules.
    Thus, the distribution of granules over the singulation disk can be improved.
    Agitating means may comprise a control device which is designed or programmed to effect pulsed drive of the singling disc. Alternatively or as a complement, agitation means may comprise a weight eccentrically arranged on a shaft connected to the disc.
    Alternatively or as a complement, agitation means may comprise an external vibrator. The device may comprise a resilient and / or steaming suspension device for mounting the device on an agricultural implement.
    Device may comprise at least one baffle, arranged aft to control a distribution of the granules Over the singulation disc.
    A portion of the baffle closest to the singulation disc may be sufficiently flexible to allow granules projecting from the slide into the singulation disc to pass the baffle in the direction of rotation of the singulation disc.
    The portion closest to the singulation disc may be formed of a rubber or rubber-like material or of bristles.
    According to a second aspect, agricultural implements are provided for feeding granules, such as exposed fertilizers or pesticides, comprising a container for said granules, a bill for discharging said granules to the ground and a singulation device, arranged to receive a first flow of 15 granules in the Iran container. and feeding a second tide of granules to the beetle.
    The agricultural implement may comprise a primary divider connected to the container, arranged to feed said granules from the container to effect the first flow of granules.
    The primary distributor may be arranged to feed said granules to at least two beetles and the agricultural implement may comprise at least two singulation devices connected to each beetle.
    The agricultural implement may include flow generating means for providing an air flow for driving at least the first flow of granules.
    Alternatively or as a complement, the container may be coated higher up than the singulation device, so that the first flow of granules is substantially accomplished by gravity.
    According to a third aspect, there is provided a method of singulating granules, such as fertilizers, fertilizers or pesticides, in an agricultural implement. The method comprises that the granules, in a singulation device, are caused to pass one hall through a habit in a singulation disc which is customary at a time. The method may comprise moving the singulation disc and again only allowing one granule to pass the respective halter when the singulation disc, and thus the halo, is at a trout-determined position.
    The method may comprise providing said granules in a container, providing after first flow of granules from the container to the singulation device and feeding from the singulation device after second flow of granules to a bill for discharging said granules to the ground. The process may comprise providing the first flock of granules by means of a primary distributor connected to the container.
    The method may comprise providing at least two first flows of granules, in each of at least two singulation devices receiving one of said first flows of granules, in each respective singulation device providing a respective second flow of granules, which is smoother than the first floc and aft from the respective singulation device feed the granules to a respective bill.
    The method may comprise providing an air flow for driving at least said first flow of granules.
    As an alternative or complement, the process may comprise achieving the first flow of granules substantially by gravity.
    In the process, the singulation disc can be caused to rotate relative to a housing of the singulation device.
    The method may comprise rotating the singling disc at a rotational speed which is related to a feed rate of the agricultural implement.
    The method may comprise rotating the singulation disc sufficiently near a bottom portion to have a sheath, so that the Mien together with the lower part form a bottom sheath, each of which is designed to receive a granule.
    The method may comprise preventing granules which have not been received in a bottom hall from being carried with the singling disc at an outlet portion of the singulating device.
    Thus, only a certain amount of granules is added to the outlet. The method may comprise guiding granules brought from the singulation disc, which have not been received in a bottom hall, so that these are moved at least radially relative to the singulation disc.
    This facilitates the fading of the granules over the singulation disc, which contributes to achieving an even outflow of granules.
    The method may comprise applying a force, substantially in a feed direction, to granules received in the halo of the singulation disk, so that these are released from the singulation disk to form the second flow.
    The method may comprise bending the singulation disc in a direction substantially perpendicular to it, so that the granules received in the hall of the singling disc are received.
    In the process, air entering the first river can be allowed to pass through the singulation disk so that none in the second river.

    Operating may include repeating the steps, scanning, stopping the drive, driving the singling disc in a reverse direction, stopping the driving again, and driving the singling disc forward, at least twice; and to then thereafter provide an indication to a user that an error is present.
    The method may comprise sensing a level of granules in a singulation space in the singulation device. In this case, the method may also comprise controlling a real-time singulation disc based on the level, controlling a feed rate of granules to the singling device based on the level and / or providing a level status indication based on the level. The level status indication can be used as an alarm signal to a user, to indicate, for example, that there is an error or that the advance speed is too high.
    The method may comprise recording granules discharged from the singulation device 5. In this case, the method may also comprise controlling a movement of the singulation disc based on the recording, all controlling a feed rate of granules to the singulating device based on the recording and / or providing an output status indication based on the recording.

    The drive unit 15 may be connected to a drive hub 23, which may be wholly or partly located inside the singulation space S and which may be adapted to receive the singulation disk 19.
    The drive hub 23 may have a base portion 230 which forms a vertical support for the singulation disc 19 and a shaft 231 which forms a ski in horizontal directions for the singulation disc by the shaft 231 engaging a center hall 193 of the singling disc 19. Furthermore, the drive hub 23 may have a guide pin 232, which is designed to engage a guide socket 194 of the singulation disc 19 (Figs. 12a, 12b) to prevent improper mounting of the singulation disc 19.
    The singulation device 1 can further comprise a pressure device 20, which can help in the event of a rotational position of the singulation disc 19, i.e. at the outlet 14, push in the Mien in the singulation disc 19 received extended out through the back of the singulation disc and thus to the outlet 14.
    The pressure device 20 shown in the example comprises a mounting plate 203 for fastening in the mounting portion 114 of the upper part 11, an arm 200, which by means of a spring 201 can be biased towards the singulation disc 19 and a pair of holding arms 205 which are integrated with the arm and at which an axle 204 is mounted. AxeIn 204 can support a pressure wheel 202, which has a plurality of projections 206, which are adapted in shape and size to be received in the tail 191 in the singulation disc 19 and thereby exert a pressure force on the tail 191 received exposed. The pressure wheel 202 may have a generally frustoconical shape, which may be adapted to the design of the singulation disc 19.
    The singulation device 1 may have a material guide grid 21 (Fig. 7) which may be arranged between the inlet 13 and the pressure device 20. The material guide grid 21 may be shaped to let air through but not exposed, so that the seeds fed to the singulation device 1 via the inlet 13 are directed to the singulation space S , at the same time as the air flow carrying the seed 15 is allowed to pass through the material guide grid 21 and further through the singulation disc 19 to the outlet 14.
    The material guide grid 21 can be designed as a ramp, which extends over a significant part of, preferably the entire, area 13 of the inlet 13. the material guide grid 21 may have an acute angle relative to the singulation disc 19. The material guide grid 21 may have a plurality of through slots 211. The slots 211 may extend substantially tangentially relative to the singulation disc 19.
    Figures 10a and 10b show an embodiment of singulation device 1 'where baffles 22a, 22b, 22c, 22d are mounted on the bar portions 112a, 112b, 112c, 112d, 112e, 112f, 112g, so that when the singulation disk 19 rotates R displaces on top of the singulation disk 19 brought radiating radially and thereby improve the distribution of the radiated Over singulation disc 19 and Increase the chance that the radiated are received in all halls 191.

    The second and fourth baffles 22b, 22d may substantially extend from the side rocker 101, 111 and obliquely.
    As also shown in Fig. 10b, the divider cradles 113a, 113c are loosely prevented from reaching the outlet 14.
    Fig. 11a shows a first alternative design of a singulation disc 19 ', where one of the Mien 192 is larger than the other hall 191. In this embodiment, the two radially adjacent halls are connected to form a hall which thus has just over 200% cross-sectional area compared to with Other hall 191.
    Fig. 11b shows a second alternative embodiment of a singulation disc 19 ", where one of the tails 192 'is larger than the other tails 191. In this embodiment, the two tufts adjacent to the direction of rotation R are connected to form a tread which thus has just over 200 Fig. 11c shows a third alternative embodiment of a singulation disc where the side of the singulation disc 19 facing the singulation space S— has a plurality of projections 195 which are located on 20 material portions coated between Mien 191. The projections 195 may have in direction Tightening cross-sectional area towards the singulation space S. For example, they may be shaped like cones, pyramids or party hazards.The committees reduce the risk of granules lying between Mien 191. It is understood that the committees may be colored by axes or the like to further reduce the occurrence of flat surfaces on which granules can be left lying without being dropped into Mien 191.
    It will be appreciated that the singling disc may have a plurality of enlarged halls 192 ', 192 "as shown in Fig. 11a and / or as shown in Fig. 11b and a plurality of projections or shafts as shown in Fig. 11c.
    Fig. 9 shows how a bypass channel 30 is arranged to bypass the singulation device 1 '. The bypass channel 30 may be formed as a separate part, which is applied after the singulation disc 19 and any pressure device 20 have been removed, or as shown in Fig. 9, as an integral part of a separate upper part 11 '. Through the bypass connection channel 17, the seedlings are prevented from entering the singulation space S, and the stall is led directly to the outlet 14. This can be advantageous when using the agricultural implement for sowing of chlorine which does not lamp itself for singulation, such as oats.
    Figs. 13a-13c show an embodiment where the singulation device 1 is provided with an air collecting part 24. The air collecting part 24 collects the air which has passed through the slots 103a, 103b, 103c in the bottom surface 102 of the lower part 10 in a collecting space 241 and leads the air to a collecting outlet 242.
    Fig. 14 shows an embodiment in which a return channel 243 connects the collector outlet 242 to the outlet 14 of the singulation device 11v, whereby a "closed" system is provided, where all, or substantially all, air is led down to the saber 7.
    In the foregoing, embodiments have been shown in which the drive unit drives the singulation disc 19 to rotate, whereby a pressure wheel 202, through sieve engagement 15 with the singulation disc 19, is caused to rotate.
    Fig. 15 shows an alternative embodiment in which the drive unit 15 'is arranged to drive a pressure wheel 202, the pressure wheel, by its engagement with the singulation disc 19, driving it.
    It will be appreciated that the embodiments of Figs. 1-14 and Fig. 15 may be combined, i.e. Driving of both singling disc 19 and pressure wheel 202 may occur.
    It will be appreciated that the pressure device 20 may be designed in different ways. In the example shown, a spring-loaded arm with a pressure wheel mounted relative to the arm is thus used, which has projections which engage with the Mien in the singulation disc 19.
    According to a first alternative, the pressure wheel 202 may have a substantially smooth periphery.
    The periphery of the pressure wheel 202 may be sufficiently soft to be compressed when pressed against the surface of the singulation disk, so that portions of the periphery of the pressure wheel bulge into the Mien 191 'singulation disk 19.
    The arm 200 may be flexible and resilient in itself, instead of being provided with a separate spring. Instead of a pressure wheel 202, the arm 200 can provide slack contact with the singulation disc 19. Optionally, the part of the arm 200 which abuts 18 against the singulation disc 19 may have projections (not shown) projecting into the tail 191 without substantially interfering with and preventing relative movement between the arm 200. and the singling disc 19.
    The singulation disk 19 may be formed of material that is sufficiently flexible to allow the singulation disk to bend toward the outlet 14 at the portion loaded by the pressure device 20.
    As an alternative, or complement, the singulation disc 19 may be sufficiently flexible to allow between portions of material 191, 192, 192 'coated material to spring to facilitate release of the tail 191, 192, 192' 10 received exposed.
    Such a flexible singulation disc 19 can be provided, for example, of rubber or rubber-like material.
    The lower part 10 and the upper part 11 can be designed in order to be able to easily be connected to ice and thereby allow access of the singulation disc 19 for inspection or replacement. The fastorons 104a, 104b, 104c, 116a, 116b shown in the example. 116c can thus be replaced by a quick coupling.
    The drive unit 15 may be fully or partially axially retracted into the singulation space S to provide a more compact singulation device.
    The singulation device 1, 1 ', 1 ", 1—, 11v is advantageously placed as close to the sabile 7 as possible. For example, the outlet 14 of the singulation device 1, 1', 1", 1 ", 11v can connect directly to the sabile, without intermediate tubes or hose.
    The singulating device 1, 1 ', 1 "can further be provided with an agitating device.
    Such an agitating device can be provided by suitable programming of the drive unit 15, for example so that the motor 6 provides stepwise driving of the singulation disc 19.
    Alternatively, an eccentrically placed weight can be arranged in connection with the output shaft of the engine, in the transmission 152, on the drive shaft 153, on the drive hub 23 or on the shaft 231.
    In cases where agitation device is used, the singulation device can suitably be mounted relative to the agricultural implement via a resilient and / or steaming device, for example in the form of one or more rubber bushings. 19 The description will now focus on the function of the singulation device 1.
    Before operation, the singulation device 1, 1 ', 1 "is provided with a singulation disc 19 whose neck size and / or neck shape is adapted to the desired 5 type of exposed. In the agricultural control unit's central control unit, the desired amount of exposed per area unit or length unit is entered or selected. Alternatively, the type of disc can be selected directly in the central control unit, whereby pre-programmed values for the number of slides, etc., are retrieved.
    When driving, the desired rotation speed for the singulation disc 10 is calculated based on the desired amount of exposure, type of exposure, the design of the singulation disc and the current cutting speed.
    As mentioned initially, a first flow of seed-mixed air is produced from the primary distributor. This first flow is led via, for example, hoses or pipes to a plurality of singulating devices 1, 1 ', 1 ", 1", 11v as described above. The outlet 14 of each singulation device is connected to a respective saber 7.
    The singulation device 1, 1 ', 1 ", 1", 11v is driven, as described above, so that the singulation disk 19 is caused to rotate 1001 about an essentially vertical axis.
    The first flow is fed through the inlet 13, whereby air, but not exposed, is allowed to pass straight through the material guide grid 21 and further to the outlet 14. The seed, on the other hand, is guided by the material guide grid 21 towards the part of the singulation space S, seen in the direction of rotation R from the outlet 14. In the singulation space S, the exposed, possibly assisted by baffles 22a, 22b, 22c, 22d and / or agitation is allowed to fall into the bottom hall formed by the tail 191 in the singulation disc 19 and the bottom surface 102 of the lower part 10. The exposed as received in Mien 191 by means of the rotation R of the singulation disc through the singulation space S, past the dividing cradles 113a, 113b and up to the outlet 14, where a hall 106 lined with the outlet 14 allows the seed to pass through the singulation disc 19 to the outlet 14, where with the help of the air that has passed through the material guide grid on to the sabile. Optionally, the passage of the seed through the singulation disc is assisted by the pressure device 20, which also helps to clean the singulation disc 19 hl 191.
    Referring to Fig. 16, the singling device 1, 1 ', 1 ", 1", can be formed so that it autonomously handles smaller operating disturbances, for example those which meant that the rotation of the singling disc 19 was completely or partially prevented.
    All rotation of the singulation disk 19 can be detected, for example, by feeding 1002 the current to the motor 150. Alternatively, a sensor (photosensor) may be used to record the rotational speed of the singulation disk 10 or an output sensor 402 which detects outgoing bias may detect a deviation in the output rate.
    In test 1003 ay the unloading result, it is determined whether operation should continue (ie the unloading result indicates no disturbance) or if there is an operational disturbance.
    If a malfunction is present, the rotation of the singling disc 194 is stopped. Thereafter, the 1005 singulation disk 19 is operated with a large, and preferably highest available, power in a reverse direction —R, for a period corresponding to less than 1 vary, preferably less than 0.5 vary, less than 0.25 vary, less than 0.1 vary or less than 0.01 vary. Expressed in operating time, the drive in the reverse direction can be effected for about 0.01-0.2 seconds.
    The singling disc is then driven again in 1006 with a large, and preferably the highest available, power in the forward direction R, for a period corresponding to 110 times the drive in the reverse direction —R, preferably 1-5 times, 1-3 times or 1-2 times.
    Thereafter, operation 1007 can, but must not, be stopped for flight detection 1002 as to whether there is a malfunction. Alternatively, the scanning 1002 takes place during the forward drive 1006, while normal forward drive is taken if no fault is detected. The procedure 1002-1007 can be repeated a predetermined number of times before an error signal is generated to the user or to the central control unit.
    In the singulation space S, a level sensor 401 (Fig. 13c) for sowing can be arranged, whereby the feed rate of the primary distributor and / or the rotation speed of the singulation disk 19 can be controlled at least also based on a value from the 21 level sensor, in order to maintain a predetermined sowing space N for example, use sound or light to feed the current level in the singulation space S.
    At the outlet 14, an outlet sensor 402 (Fig. 13c) for outgoing outlets 5 can be arranged, so that the discharge rate from the singulation device 1 can be monitored and the operation of the singulation device can be controlled to achieve a predetermined discharge rate. The outlet sensor 402 can be provided in the form of a dispenser of the type available on the market. The outlet sensor can be arranged in or downstream of the outlet 14, i.e. It may form part of the singulation device, part of a bill, or part of an intermediate line.
    It will be appreciated that the signal from the outlet sensor 402 may be considered to be the value which best represents the function of the singling device, since the signal tan the outlet sensor together with the feed rate of the agricultural implement 15 determines the resulting distribution of the seed, at least as long as no fault occurs in the outlet. so that the rotational speed of the singling disk is controlled based on the signal from the outlet sensor 402 to provide the right amount of output output, thereby controlling the feed rate of any primary distributor based on a signal from the level sensor 401. Optionally, an error signal may be generated from the leveler 401. , which may indicate that the feed rate is Mr high.
