15 20 25 30 9022l, l0l0 2 The row units should be able to be mounted on the machine to achieve different mutual row spacings. It should be possible to vary the row spacing from a large row spacing, for example for maize approx. 75 cm, to a small row spacing approx. 37 cm, which is desirable, for example, for certain crops such as soy. It may then be necessary for at least one row unit to fit under the frame in the middle of the machine. The folding should usually be possible from the driver's seat, without the driver having to get out of the towing vehicle. Another important criterion is that the machine does not become unnecessarily long. A long machine is difficult to handle in tight spaces and it cuts hard in tight turns, for example when the farmer has to turn down from a road and pass a gate hole on the way out to the field. Many prior art agricultural machines of this type with folding systems have shortcomings in these aspects.
OBJECTS OF THE INVENTION The object of the invention is to provide a felling device in an agricultural machine which, in addition to solving the above-mentioned problems, also results in an optimal arrangement and provides the greatest user-friendliness. The solution should also be reliable, cost-effective and easy to use.
BRIEF SUMMARY OF THE INVENTION The object is achieved by a precipitating device according to the characterizing part of claim 1.
The subclaims state advantageous embodiments of the invention.
The felling device according to the invention means that the agricultural machine with sawing unit can be built in four or five sections on a central frame. One can also imagine two or två your beams which all support units for tillage, sowing etc. The central frame has a drawbar for connection to a towing vehicle and it can also support a central tank for transporting fertilizer and / or seed. The central frame also usually has wheels to be held at a predetermined position above the ground. At least one saw unit can also be mounted on the central frame. Adjacent to the central frame, an intermediate part in the form of an intermediate beam or intermediate wing is pivotally mounted. This intermediate beam, which also supports row units and possibly support wheels, is built to be articulated partly so that it can follow the irregularities of the ground, partly so that it can be folded up and then stand more or less vertically. in a transport or parking mode. Outside each intermediate beam there is an outer part in the form of an outer beam or outer wing, which also supports row units and possibly support wheels. These outer beams can have gra your degrees of freedom to allow the machine to follow the unevenness of the ground in a suitable way. They have a degree of freedom that allows the sections to be folded approx. 180 degrees forward. The pivot axis between each intermediate beam and the outer beam connected thereto is arranged as far out as possible substantially at the level of the ends of the beams in order thereby to obtain as low a machine as possible in the transport or parking position.
The outer beam can also be provided with a universal joint where the horizontal axis allows a mobility of approx. i5 degrees. The inner pivot axes of the intermediate beams are positioned so that a larger space is created between the frames in the folded position to provide space for accessories for tillage, fertilization or other desired equipment.

DESCRIPTION OF A PREFERRED EMBODIMENT Corresponding details in the embodiments described below and shown in the drawings have been given the same reference numerals.
Fig. 1 shows a side view of an agricultural machine or plants 1 of the current type. It is towed by a tractor 2 or other suitable towing vehicle. The machine 1 has a central frame, which comprises a central frame tube 3, which is advantageously built of a strongly central, laterally seen substantially S-shaped tube, preferably a square tube, and which extends in the longitudinal direction of the machine. At the front end of the rake tube 3 a coupling 4 is arranged for connection to the tractor 2 of the tractor 2. Electricity and hydraulics are fed from the tractor 2 to the machine 1 via lines 6. A fl device 7 is arranged on the frame tube 3 for feeding seed and / or fertilizer to saws. in the form of plant assemblies / row units 8, which on both sides of the machine 1 are mounted on intermediate parts hingedly mounted at the frame tube 3 in the form of intermediate beams 9 and we these hingedly arranged outer parts in the form of outer beams 10.
At the rear of the frame tube 3 a container 11 for fertilizer or seed is mounted, which has a support wheel 12 mounted on each side. The container 11 is provided with conduits 13, 14 for feeding seed or fertilizer to the row units 8. See the cross section of the machine in Fig. 6, in which the rake tube 3 and a central section 4 arranged therewith and the intermediate beams 9 are clearly visible. A folding device 11 according to the invention of the agricultural machine 1 will be explained in more detail in the description below of the various embodiments and comprises a cross beam divided into the intermediate beams 9 and the outer beams 10, which is arranged to support the row units 8, and outer beams 9 and 10 arranged therefrom. hinge shafts 15 and inner hinge shafts 16. The frame or runner tube 2 is designed so that the row units 8 10 15 20 25 30 90221,1010 5 can fit under the frame tube 3 so that the farmer can choose the location and division for the row units 8 so that the machine can be adapted to current crops and the line spacing referred to therein.
The support wheels 12 at the rear part of the machine 1 under the container 11 for seed / fertilizer can be fixedly mounted or be mounted on a pivotable shaft which makes it possible to raise / lower the machine. Each row unit 8 is usually suspended in link bars in the form of a parallelogram. This parallelogram can in each row unit 8 have a servo device, for example a hydraulic cylinder, to be able to be used to raise / lower the row units, which can replace the requirement to raise / lower the entire machine.
The seed and fertilizer delivery system may be mechanical or pneumatic or otherwise arranged. This system is indicated but not all parts are shown.
For example, there are also containers 17 and 18 for fertilizer or seed on each row unit 8.
The machine may also include a device for laying / laying manure in connection with sowing. A plate 19 that cuts a notch in the ground is depicted. This includes a seed beetle and a pipe that leads the fertilizer.
In front of the fertilizer plate 19, a working tool 20 for tillage is drawn. In this example in the form of a so-called leveling pin 20, one can also imagine a wide range of work tools or combinations of work tools such as harrow sticks, discs, pressure rollers CÉC. Above the leveling pin 20, a pivot point 21 is indicated. This guide point can be selected with regard to how far in front of the frame tube 3 different means may extend.
Fig. 2 shows a first embodiment of a machine 101 of the current type seen from above.
This machine 101 has outer beams with four row units 8 each, where one outer beam 101a or the wing (on the right in the figure) is recessed in an intermediate position and the other outer beam 101a (on the left in the figure) is extended in a working position. The intermediate beams 101b each carry five row units 8. Both outer beams 101a are suitably folded against the frame tube 3 around the outer hinge shafts 15 before the next folding phase begins the vertical folding around the inner hinge shafts 16. As can be seen from the plan view in fi g. 2, support wheels 22 are mounted on the intermediate beams 101b and the outer beams 101a. This machine may comprise working means 23 for tilling in front of the transverse frame and the hinge axes 16 of the outer beams 101a have therefore been moved forward in the direction seen through brackets 24 and 25 to a position sufficient for the working means 23 not to come into contact with each other and be damaged in the fall. The lowering of the outer beams 101a can be done with servos as hydraulic cylinders or can possibly be manual for smaller machines. Fig. 2 shows a variant with manual folding of the outer beams forward in the direction of travel, but with hydraulic cylinders 102 for folding the intermediate beams 101b upwards to a substantially vertical transport or parking position so that the outer beams 101a and the intermediate beams 101b become substantially parallel to each other and where the outer ends 26 of the outer beams can abut during transport against and be locked to locking devices not shown on the intermediate beams 101b.
The hinge shafts 15 on both sides of the machine between the outer beams 101a and the intermediate beams 101b can be designed to give about 180 degrees of folding possibility around a, in working position, substantially vertical axis. It can also be designed to provide limited mobility around a horizontal axis (not shown) so that the machine can better follow the unevenness of the ground. This degree of freedom can also take place by means of elastic elements (not shown) being built into or near the joint.
Fig. 3 shows a second embodiment of a machine 201, which has hydraulic recessing of both the intermediate wings 20la and the smaller outer wings 20lb by means of hydraulic cylinders 202 resp. 203. The right outer beam 20la in Fig. 3 has been folded to a position close to the final recessed position substantially parallel to the intermediate beam 20lb, while the left outer beam 20la in Fig. 3 is in the working position.
Fig. 4 shows a third embodiment of a machine 301 with outer beams 30la and intermediate beams 301b with each equal number of row units 8, as in the second embodiment according to fi g. In the case of shorter outer beams 30la, it is possible to use a mechanical recess which can be connected to the recess of the intermediate beams 301b 301 (25 vertical recess). The dashed line indicates a strut 302, which extends between the mechanism of the outer beam 30la for folding at the hinge axis 15 and to a point below the hinge axis 16 of the intermediate beam 30lb. When lowering each intermediate beam 30lb, the outer beams 30la also fall by tensile forces in the hinge joints 303, which are spaced apart. from hinge shafts 5 between the outer beams 30la and the intermediate beams 30lb. You can thereby achieve a simple and uncomplicated function, which is very cost-effective.
The upward folding of each intermediate beam 30lb takes place by means of hydraulic cylinders 304.
Fig. 5 schematically shows a fourth embodiment of a machine 401 in so-called "Split row" - configuration ie. that the machine 401 has been equipped with significantly fl your row units 8 to be adapted for a crop that requires a smaller row spacing. In this case, two parallel and offset rows of row units 8 are shown along outer beams 40 1a and intermediate beams 401b. Soy and sugar beets can be examples of crops that are sown / planted with about half the line spacing in relation to maize. It can be seen that here the entire back of the beams needs to be available for row units 8 and a row unit 8a therefore needs to be mounted under the frame for the sake of symmetry, ie. in the middle of the machine. Otherwise, this machine is folded as in the embodiments described above. In the direction of incidence of the outer beams are indicated by arrows 402. In this embodiment, the outer beams 40la are folded manually and the intermediate beams 40lb by means of hydraulic cylinders 403.
Fig. 6 generally shows a cross-section on a larger scale through a collapsed machine 1 according to one of the described embodiments, in this case according to fig. As can be seen from Fig. 6, the machine may comprise the central frame in the form of the frame tube 3 with a supporting frame section 3a, to which the intermediate beams are articulated at 16.
Figs. 7-8 show a fastening bracket 26, which is releasably lockable on either side of the agricultural machine 1 on either the rear side 20ab of the outer beam 20la or the middle beam 20lb 27 by means of clamp / screw connection 28. The side edge 27 is also used, as shown in Fig. 7, for locking of the row units 8 at intermediate resp. outer beams. Mounting brackets 26 are used when an additional row unit 8b needs to be mounted at some hinge shaft, for example the hinge shaft 15 in FIG. 7. Without the use of mounting brackets 26, at least one area may arise around the hinge shafts 15 and 16 where p. the joint between the outer beam and the intermediate beam is not possible to mount a further row unit 8b between the row units 8 on these intermediate and outer beams. A complete machine solution requires that row units can be mounted along the entire width of the machine at predetermined distances. This is then a very good solution for being able to mount row units anywhere on the frame beam. Fig. 8 shows the fastening bracket 26 with the clamp / screw connections 28. I fi g. 8, the claw / screw connections 28 are mounted through the right hole pairs, but they can also be mounted in the left hole pairs 29 shown in the figure, depending on which beam the fastening bracket 26 is intended to be mounted. Other types of attachments of the mounting brackets 26 than the one shown and described above are of course possible.
Fig. 9 shows a fifth embodiment of a machine 501 with discs 32 for tillage, where two parallel frame beams are connected to a central beam 30 with a coupling 31 for a towing vehicle (not shown). At the rear end of the central beam 30, two support wheels 33 are mounted on a transverse wheel shaft 34 connected to the beam 30. The machine 501 has the outer beams 50la horizontally foldable to be folded approx. 180 degrees to an intermediate position by means of hydraulic cylinders 502 and then folded to the transport or parking position by means of hydraulic cylinders 503, where the intermediate beams 50lb are folded up substantially vertically in accordance with the embodiments described above. Here, too, the pivot points 15 between the outer beams 50la and the intermediate beams 50lb are substantially level with the ends of the latter in the recessed position (transport or parking position) to provide as low a recessed machine as possible.
Fig. 10 shows a sixth embodiment of a machine 601 with two main beams, namely outer beams 601a and 602a and 602a, respectively. intermediate beams 601b and 602b. These in this case carry plates 32 for tillage. Each of the main beams 601a, 602a, 601b 602b has a shaft which carries plates 32 for tillage. In this case, each plate 25 is resiliently connected to its resp. shaft by means of a resilient member. The outer beams 601a and 602a of the main beams can be folded in approx. 180 degrees before the entire main beams, ie. the intermediate beams 601b with the outer beams 601a fold upwards to end in a substantially vertical position for storage and road transport. Fig. 10 shows the front outer beams 601a with hydraulic folding by means of hydraulic cylinders 603 and the rear outer beams 602a with manual folding to exemplify. The upward folding of the intermediate beams is effected by means of hydraulic cylinders 604. This machine 601 also has a central beam 30, which is supported by rear support wheels 33. Fig. 11 shows a cross section through a seventh embodiment of a machine 701 of said type. with only two row units on each outer beam 701a. Therefore, only one wheel 22 is needed in practice on either side of the beam pairs 601a and 60lb. The figure shows how the linkage bars 702 for the recess of the outer beams 701a approx. 180 degrees are fixed in the frame at a point below the articulation points of the beams. As the machine collapses, the intermediate beams fall upwards. As the wings fold up, the linkage rods 702 can rotate in the wings a total of about 180 degrees. This is a simple and cost-effective solution especially when the outer beams 701a are smaller. A corresponding precipitation device is shown in f1g. 4. In the case of larger outer beams, it may be an advantage to hydraulically fold in the outer beams 701a before the upward tilting of the intermediate beams 701b is started by means of the hydraulic cylinders 703, as shown in fi g. 3.
Fig. 12 shows an eighth embodiment of a machine 801 with five beam sections, namely two outer beams 80la, two intermediate beams 80lb and a central part in the form of a central beam 801c. Since the requirement for a very narrow transport width is less important, the machine may comprise a central beam 801c, along which a pair or a few row units 8 are mounted.
The outer beams 80la and the intermediate beams 80lb are pivoted forward resp. upwards by means of hydraulic cylinders 802 resp. 803 In the following, the folding operation of the machine is described by means of the device according to the invention: The folding operation begins with the outer beams being swung forward in the direction of travel, seen hydraulically, manually or otherwise approx. 180 degrees. When this operation is performed, the middle wings fall upwards and the outer beams then follow you in this movement. This movement can alternatively be coupled so that the outer beams fold in automatically with a mechanical or hydraulic coupling at the same time as the intermediate beams fall upwards. In the event of a failure, the same thing happens, but in reverse order. The construction method has here mainly been exemplified with a device according to the invention mounted on an agricultural machine in the form of a planter, but other types of agricultural machines can of course be provided with the same felling system, for example a ring roller. The device according to the invention is best suited for machines with a limited length extension. In order to allow movement to absorb irregularities in the ground, the vertical, second articulated shaft 15 in the working position may be provided with a horizontal articulated shaft or consist of a universal joint where the horizontal shaft allows a mobility of approx. d: 5 degrees.
The invention can be varied in a number of different ways within the scope of the appended claims. For example, modifications may involve combinations of the described embodiments.
