    Object of the invention The object of the invention is to solve these problems by eliminating double fertilizer lines and creating a device with only one supply line for bulk material to each pick-up beetle from a commonly placed bulk storage in the agricultural machine.
    The object is further to provide such a device for a loosening beetle which distributes the bulk material proportionally to different levels in the ground.
    An additional purpose is to be able with this device to regulate the proportion of bulk material to different levels in the ground.
    In addition, the object of the invention is to distribute the bulk material in a uniform manner so that the bulk flow is substantially homogeneous when the bulk material passes the device.
    SUMMARY OF THE INVENTION The present invention, as set forth in the independent claims, fulfills the above objects, thereby eliminating said drawbacks. Suitable embodiments of the invention are set out in the dependent claims.
    The invention relates to a distribution nozzle for primarily bulk-shaped fertilizer, but also other bulk-shaped goods such as seeds, pesticides or the like, in close connection with a pick-up beetle. This distribution nozzle is provided with at least two outlets. These outlets can also be regulated.
    The pick-up beetle or supply line can be provided with a device which disturbs / splits the bulk flow so that it is homogeneously distributed when it passes the distribution nozzle. This can be done in different ways. One way is to lay at least one transverse element across the flow direction, or alternatively several elements, in the supply line. If the supply line is provided with a bend of at least about 15 degrees and which is oriented across the outlets, the bulk goods, such as the fertilizer (or seed if applicable), tend to flow uniformly down the loosening beetle.
    A uniform flow in all distribution nozzles is desirable in order to be able to divide the flow in a predetermined manner. To further increase the uniformity of this flow, the bend of the supply line can be provided with irregularities or wrinkles to further distribute the flow in a uniform manner at all loosening beetles. Furthermore, the distribution nozzle can be provided with a slot of suitable length along the rear edge of the nozzle or alternatively with elongated holes in which slot or hole an adjustable reflector arranged to reflect the desired part of the bulk material, for example the fertilizer, at the desired level.
    This reflector can be placed in different vertical positions in slots / heels so that the user can choose the deep position for the bulk material that is optimal. This reflector is arranged to be able to be inserted into the desired depth of the distribution nozzle. When the reflector is fully inserted, 100% of the bulk material is reflected out at an upper level. When the reflector is inserted halfway into the bulk stream, 50% of the bulk material is reflected out at an upper level and 50% is reflected out at a lower level. If necessary, a third delivery level, corresponding to a third outlet, can be established if an additional reflector is introduced into the distribution nozzle, whereby the bulk flow is divided into three different flows for three different levels in the ground.
    More specifically, the invention relates to a distribution nozzle for an agricultural machine, which nozzle is placed adjacent to a trailing edge of a loosening beetle which is designed as a, in a working position, substantially vertically directed member with a downwardly directed tip. A bulk container is connected via a delivery channel to the said distribution nozzle in order to deliver bulk material through the delivery channel to the distribution nozzle and further through the distribution nozzle down behind the opening beetle. The distribution nozzle is provided with at least two outlets and with a distribution device which distributes the amount of bulk material to said outlet. Said distributing device comprises at least one reflector placed in the distribution nozzle whose inner edge acts as a division of the flowing bulk material so that a part passes past the inner edge and a part is deflected by the edge and distributed along the reflector. In addition, the said reflector is detachably and adjustably mounted in the distribution nozzle. This possibility of adjustable division of the bulk stream constitutes a simple and reliable distribution of the bulk material at the same time as the bulk stream can be handled in a desired manner.
    The fixing of the reflector in the distribution nozzle can be achieved by the side walls of the nozzle being pressed by means of a pressing action between the side walls of the nozzle, whereby the reflector is retained by friction against the side walls. The fleece reflector can be made of a rubber material or a plastic material. It can also be provided with a friction-increasing surface structure. The pressing action of the nozzle 4 can be achieved by a conically shaped nozzle, by a resilient nozzle or by a mechanical clamping device arranged in the nozzle. In one embodiment of the invention, the distribution nozzle and the reflector are provided with mutually engaging locating means for a locationally fixed fixation of the reflector in the distribution nozzle. These locating members may be projections which engage in recesses or pins which engage in holes. These trades are placed on the reflector while the female parts are placed in the distribution nozzle or vice versa. The nozzle-related locating means may also be located at several different vertical levels in the nozzle.
    In an embodiment of the invention, the reflector is mounted in a groove in the nozzle and slidably movable along this groove and lockable in any position in the groove.
    The displaceability means a stepless distribution of the bulk material to different depths in the ground. The grooves may be curved to hold a curved reflector. The reflector can alternatively be cupped to obtain a total bulk flow along the reflector.
    The lockability can be achieved by using a screw connection to compress the reflector grooves and thereby wedge the reflector. Another alternative is that the grooves are designed with a permanent pressing effect to hold the reflector.
    In an embodiment of the invention, the distribution nozzle is connected to the vertically directed member, i.e. the opening beetle, either by a screw connection directly against the member or by the distribution nozzle being firmly integrated with the member. Other connections of the distribution nozzle in connection with the loosening beetle are also possible, for example that the distribution nozzle is mounted on a frame part of the agricultural machine.
    In an embodiment of the invention, the distribution nozzle is provided with several grooves, for placing the reflector in one of these grooves. This embodiment enables the reflector to guide the bulk material to alternative levels only by moving the reflector to an alternative track.
    In an embodiment of the invention, a reflector placed in several is one of said tracks. In such an embodiment, more than two outlets are obtained for distributing bulk material to more than two levels in the ground.
    In one embodiment of the invention, said reflector is formed as a flat disk.
    In an embodiment of the invention, said grooves are rectilinearly shaped. This design of a flat reflector which can slide in rectilinear grooves in the nozzle is the simplest of the indicated embodiments and also easiest to adjust with regard to the division of the flow in that the reflector can be knocked inwards or outwards as desired, for example with a hammer. In one embodiment of the invention, the distribution device is provided with several reflectors which are individually displaceable grooves and mounted in the nozzle at different vertical levels and inserted different distances in the flow of bulk material so that the depth position in the ground for the divided bulk currents becomes different. This embodiment has been indicated above, but in addition each reflector is individually adjustable for dividing the bulk flow. In one embodiment of the invention, said reflector is mounted at an angle d i relative to a vertical through the distribution nozzle where 30 ° <oi <80 °. As an alternative to placing the reflector in grooves in different vertical positions, the angle of the reflector in relation to the vertical line can instead also determine the level that the bulk material is to obtain in the ground.
    In one embodiment of the invention, the distribution nozzle or its supply is provided with a distortion device which deflects the direction of the bulk flow. In one embodiment of the invention, the distortion device consists in that the connection of the distribution nozzle to the supply channel is curved or inclined to deflect the bulk flow at an angle ß before it reaches the distribution nozzle where 10 ° <ß <60 °. Advantageous angles ß are 15 ° or 45 °.
    In an embodiment of the invention, the distortion device consists in that the inside of the delivery channel or the inside of the nozzle is provided with irregularities or wrinkles in order to distribute the bulk material in a uniform manner when the material passes the nozzle.
    In addition, the present invention relates to an agricultural machine comprising at least one distribution nozzle of the type set forth above.

    Description of the invention Figure 1 shows an agricultural machine 10 in the form of a seed drill which is provided with a bulk bearing 11, distribution lines 12 for bulk material, only partially shown, and discharge devices for bulk material such as saw assembly 13 and distribution nozzles 14. The distribution lines 12 are divided into delivery channels 12a, partly shown in the figure, for fertilizers and delivery channels 12b for seed. The distribution takes place with a fan, not shown, which produces an air flow through the distribution lines. The agricultural machine is further provided with a support frame 15, a traction device 16 connected to the support frame 15 and support wheels 17 for the machine, as well as various types of packing devices and color-forming devices. Preferably, the agricultural machine 10 is towed by a tractor which is coupled to the towing device 16. The agricultural machine is further provided with hydraulics for lowering / raising different sections of the machine.
    Each distribution nozzle 14 is mounted adjacent to or on a loosening beetle 18 which acts as a soil conditioner for the next sowing of actual crop. In the agricultural machine shown, the distribution nozzle 14 is detachably mounted directly on the opening beetle 18.
    Figure 2 shows the opening beetle 18 on which the distribution nozzle 14 is mounted with a screw connection 21 in a slot 22 for adjusting the mounting height of the beetle. The opening beetle 18 is formed with a downwardly directed tip 18a and foldably movable around a frame part 23 and resiliently mounted via spring elements 24 around this frame part in the agricultural machine 10. The figure further shows a hydraulic cylinder 25 active partly for the folding of the opening beetle 18 partly for stone release of billen. The distribution nozzle 14 is mounted at the trailing edge 26 of the release beetle 18 and as close to this trailing edge as possible, i.e. without appreciable play. The distribution nozzle 14 is formed with an upper connection part 28 and a lower distribution device 27. To the connection part 28 a delivery channel 12a is connected which from one side of the opening beetle 18 via direction means 29 can orient bulk material to the connection part 28. The bulk material is led down through the distribution device 27 in a first bulk stream 29a and further down into the ground to a level which largely corresponds to the pick-up depth provided by the tip 18a. The spreading part 27 provides a second bulk current 29b in that a reflector 30 is placed in the distribution device 27 at an angle d i relative to a vertical line L through the distribution nozzle 14 where 30 ° <o <80 °. In the figure, the angle oi is = 40 °. Through this placed reflector a first outlet 31 and a second outlet 32 are formed from the distribution nozzle 14. The figure also shows that the reflector 30 is mounted in paired grooves 33 in the distribution device 27 and that the reflector 30 can be displaced in these grooves according to the bidirectional the arrow in the figure. The figure further shows that the distribution device can be provided with several pairs of such bars so that either a reflector can be moved to another position in the distribution nozzle 14 or that several reflectors can be mounted at different levels in the distribution nozzle 14 in order to be able to offer more than two outlets for the bulk-shaped goods. In Figure 2, the reflector 30 is shown as a planar disk which can be displaced in and out along the groove 33. However, within the scope of the invention, the reflector may be formed as a curved disk which can be displaced in curved grooves to achieve the effect of it can also be controlled to some extent with regard to the ground depth depending on the length of the curved disc and the degree of insertion in its curved groove. The reflector can also be cupped around its longitudinal axis 8 to act as a collector on the bulk current along the surface of the reflector. In the embodiments shown, the reflector can be locked in the grooves by the distribution device 27 being compressed by a mechanical device (not shown) or the distribution device being designed with an inherent pressing action.
    Figure 3a shows a first embodiment of the distribution nozzle 14 in rear section with the first outlet 31 and the second outlet 32, which outlets are divided by the reflector 30. The figure shows the direction means 29 to which the delivery channel for bulk material is connected. The sealing means has an angle ß of 45 ° in relation to the bulk flow direction S through the distribution nozzle 14. The bulk flow through the direction means 29 must be caused a distortion in this partly by a change of direction and by bouncing against the inner walls of a conical part 35 in the direction means 29. Due to this distortion a more homogeneous bulk current is obtained through the distribution nozzle 14 and this in turn contributes to the division of the bulk current of the reflector 30 to the outlets 31, 32 becoming better proportioned. The reflector 30 is in the figure located in the lowest pairs of grooves 33 of three pairs of grooves.
    Figure 3b shows a second embodiment of the distribution nozzle 14 in section from behind with the first outlet 31 and the second outlet 32, which outlets are divided by the reflector 30. The figure also shows in this embodiment the direction means 29 to which the delivery channel for bulk material is connected. In this embodiment, the braiding means has an angle ß of 15 ° in relation to the bulk flow direction S through the distribution nozzle 14. This angle also causes the bulk flow a distortion due to the direction means 29 partly by the change of direction and by also bouncing against the inner walls of a conical part By this distortion also in this embodiment a more homogeneous bulk current is obtained through the distribution nozzle 14 and this in turn contributes to the division of the reflector 30 of the bulk current to the outlets 31, 32 being better proportioned.
    The location of the reflector 30 is also in this figure in the lowest pairs of grooves 33 of three pairs of grooves.
    Figure 4a shows an embodiment of the distribution nozzle 14 in a section from the side. The figure shows the reflector 30 which is placed in the second pair of grooves 43 from below with its flow-dividing inner edge 41 which divides the bulk flow to the first outlet 31 and to the second outlet 32. As can be seen from the figure, the reflector is inserted approximately halfway in the grooves 43, the bulk flow being approximately divided to 50% between the two outlets 31, 32. This embodiment is also provided with a distortion device in the form of a conical part 35 against which the bulk flow receives a change of direction. A relatively long mounting slot 44, which corresponds to the mounting slot 22 in Figure 2, is also shown in the figure. The distribution nozzle 14 is limited to a release beetle through a front wall 45.
    Figure 4b shows a further embodiment of the distribution nozzle 14 in a section from the side. The figure shows the reflector 30 which is placed in the second pair of grooves 43 from below with its flow-dividing inner edge 41 which divides the bulk flow to the first outlet 31 and to the second outlet 32. As can be seen from the figure, the reflector 30 is also inserted in this embodiment approx. halfway in the grooves 43, the bulk flow being approximately divided to 50% between the two outlets 31, 32. This embodiment is provided with a distortion device 46 in the form of one or more transverse axes, in the figure three transverse axes are shown of which two adjacent axes are oriented 90 ° to each other, against which axes the bulk flow, indicated by the arrow in the figure, receives changes of direction. Also in this embodiment a relatively long mounting slot 44 is shown. The distribution nozzle 14 is also limited in this embodiment by a front wall 45 arranged against a pick-up beetle.
    This said distortion device can also be designed so that the inside of the delivery channel or the inside of the nozzle is provided with irregularities or wrinkles in order to distribute the bulk material in a uniform manner when the material passes the nozzle. Combinations of these devices can also be arranged in one and the same distribution nozzle. Preferably, the distortion device is positioned before the bulk flow is oriented in the vertical direction in the distribution nozzle.
    Figure 5 shows a crop 51, in the form of, for example, rapeseed, which has been planted after the soil 52 has been worked with loosening beetles. Each pick-up beetle is each provided with a distribution nozzle according to the invention, in this case with two outlets. Through the first outlet of the distribution nozzle, in this case a first fertilizer concentration 531 has been delivered to a first deeper level N1 in the ground, while the second outlet of the distribution nozzle has delivered a second fertilizer concentration 532 to a second shallower level N2.
    The present invention thus shows that bulk-shaped goods, such as fertilizers, can also be distributed to more than two depth levels in the ground by allowing several reflectors to be used in one and the same distribution nozzle. In further embodiments, the lower end of the distribution nozzle is provided with a bottom wall which helps to prevent accumulations of soil and rock blocking the nozzle. In this embodiment, at least two outlets directed backwards are obtained.
