    10locking screw. This device is not completely safe as the pin can easily slide in the hub hole orthe screw can simply be broken off.
    In need of greater working depth and in combination with larger amounts of crop residuesthe cutting angle must be smaller in the order of 12-14 degrees to enablea noise-free queue. To some extent, this is also linked to the degree of cuppingthe plate has.
    Problem statementThe object of the present invention is to provide a method and agear control device in the case of an agricultural implement of the initially mentionedwhich solve the above problems.
    Brief description of the inventionThe object is achieved with a method and a tool control device at oneagricultural implements, which device has been given those of claims 1 resp. 4characteristic features.
    Preferred embodiments of the method and the tool control deviceaccording to the invention the characteristics set forth in the subclaims have been given.
    If you provide the hubs of the plates with a shaft that is angled a few degrees andat the same time arranges so that it can be rotated and locked in different positions, so you get oneadjustable plate angle. The possible setting angle variation will be double the pinbending angle. This is known per se, e.g. through prototypes manufactured. Onlyhowever, this solution is not perfect as it is very difficult to after a whileuse turn the pin as soil, dirt and rust cause the shaft to jam in the sleeve. Theimproved solution according to the invention means that the pin is given a pre-bondedfuse against the hole in the lower end of the arm. To be able to loosen the pin when changingof the working angle of the plate, the pin is preferably given a substantially conical forearm, i.e.partly conical with chamfers arranged in the direction of the horn, so that the outer of the pinshape corresponds to the shape of the receiving hole in the hub of the plate, whereby aform- and force-coupled coupling is obtained. This provides a controlled opportunityto displace the pin outwards during adjustment. The adjustment then becomes very simple and candone with a few simple touches. When releasing the pin in the conical holeby partial unscrewing of a screw connection centrally fixed in the pinfacilitates turning the pin to a designated positioning position and locking it inthis position by tightening said screw connection. This gives the opportunity tochange the working angle of a plate.
    In this way, the plate can be provided with an adjustability which has only a marginal onecost impact and is durable and maintenance free. This solution means that one andthe same machine can be used under many different conditions at different working depths.
    A further advantage of the control device according to the invention is that the dressingcan be made short and compact to facilitate the passage of straw soil andPlant residues. The conformity means that the axial force absorbed by the bearing acts indirection to push the pin into the partially conforming hole, which in turn contributes toa stable unit.

    Description of a preferred embodimentFigs. 1 to 5 illustrate a preferred embodiment of a tool control device.device at an agricultural implement 1 for tillage.
    In Figs. 1 and 2, the agricultural implement 1 is shown in a working position. The agricultural tool has oneframe 2 and a pulling device 2a, which is suitably connectable to and can be pulled offa tractor (not shown). The machine 1 here comprises three rows of a, b, c implements in the form of twofront rows a, b word processing, free rotating, plates 3 and a back row c withroller assembly 4. Each plate 3 in one of the two rows a, b is turned oppositehold compared to the corresponding plate in the second row b resp. a. Such as plates 3are arranged in Figs. 1 and 2 are given in the row a a ground line b a j ö öde inwards towards the tool center. In a known manner, lines a and b are includedplates 3 and row c with the roller assemblies 4 divided into three mutually articulatedsections 5, 6 and 7. The transport wheels 8, which are mounted on the outer frame sections 5and 7, are rotatable together with the frame sections 5, 7 by means of hydraulic pistons 9a transport mode for agricultural implements 1. This principle structure of the implement is inknown. The method and tool device according to the invention are alsoapplicable to other agricultural machinery.
    Fig. 2 shows more clearly that the plates 3 in both rows a and b are freely storedat the bottom of arms 10 and mounted suspended in transverse beams 11 and 12 by means of atthe upper ends of the grooves 10 connected by welding or casting bearing means 13.
    Shot plates 14 are arranged between the beams 11 and 12.
    Fig. 3 shows on a larger scale the suspension and storage of the plates 3. Eachplate 3 is consequently attached to a hub 20, which is freely mounted around a bearing part 21b,having the shape of a substantially circular-cylindrical portion 21b of a pin 21. Itthe opposite end of the pin 21 is constituted by a coupling part 21a, which has the shape of apartially conical part 21a. The upper end of the arm 10 is provided with a storage device 13,such as a rubber suspension or other flexible suspension. The storage device 13 remainsin a known manner of two storage halves and, the lower storage half being connectedwith the arm and the upper bearing half is fastened to by means of screw / nut connectionthe lower storage half. Beams 11 and 12 (see Fig. 2) run through the storage device13 and four rubber rods can be placed between the beams 11 and 12 in a known mannerand respective bearing halves. The plates 3 are suitably screwed to the hub 20by means of screw connections 22.
    Figs. 3-5 show in more detail the method according to the invention for changingthe setting of an implement and also an implement control device forimplementation of the procedure.
    The pin 21 is rotatably mounted in a bearing 20a in the hub 20. The pin 21 is angledpreferably a few degrees ß according to Fig. 3 between the partially conical part 21acenter axis and the circular cylindrical part 21b present in the bearing 20acenter axis. The pin 21 can be rotated and locked between at least two positions, so that oneadjustable plate angle is obtained. In Fig. 3, the angle between the partially conical part is21a and the circular-cylindrical part 21b of the pin at an angle ßthe conical part 21a of the pin is rotated according to the invention 180 degrees in a substantiallypartially corresponding hole 24 in the end part 23 of the arm 10 to another position, this means thatthe plate angle relative to the partially conical part 21a can be changed to a maximum of 2ß. INthe case shown can ß be approx. 2 degrees and 2ß consequently be approx. 4 degrees. Otherdesired positions of the pin 21 and thus values of the angle ß are of course alsopossible within the scope of the claims.
    The circular-cylindrical part 2lb present in the bearing has on its against the plate 3facing side a projecting part 13 with one at the circular-cylindrical part 21bprovided, in the direction of the horn, extending notch 14 for receiving alock washer 15 for locking the pin 21 to the plate 3.
    The pin 21 is provided in the circumferential direction with a predetermined number of chamfered surfaces33 between the conical surfaces 34 of the partially conical part 2la, which in total correspondsagainst the shape of the partially conical hole 24 in the end portion 23. The intended working anglefixed by tightening a screw connection 30 when the chamfered surfaces meetcorresponding intended surfaces in the end part 23. Other configurations of the pin shapeand the corresponding shape of the hole are of course possible. The outer shape of the pin 2121a partially conical part should correspond to the shape of the receiving hole 24 in the armend part 23, whereby a pre-bonded and force-bonded coupling is obtained in at leasttwo modes. The partially conical portion 21a may be shaped to includebeveled surfaces which are preferably evenly distributed in the circumferential direction, preferablybe of an even number and preferably be four in number.
    The pin 21 also consists of a further partially cylindrical part 21c between the ithe cylindrical end part 23 of the arm, insertable, partly conical part 21a and that in the bearingpermanent, circular-cylindrical part 2lb. This part 2lc has in the circumferential directiondistributed flat portions 35 by means of a tool, such as one not shownwrench, be able to turn the partially conical part 21a of the pin 21 into the cylindrical part of the scarend part 23 when changing the positioning position of the pin 21 and thus also the linerplate 3.
    The screw 30 of the screw connection centrally through a hole 31 in the end part 23is screwed into a threaded hole 32 in the pin 21. When releasing the pin 21 in the partiallyconical hole 24 by partially unscrewing the central fixing in the pinscrew 30, the pin can be turned to a new intended positioning position and locked in placethis by tightening the screw 30. This makes it possible to change a plate3 working angles.
    The threaded portion of the threaded hole 32 should be long enough to loosenthe screw 30 for turning the pin 21 to a new intended position, the screw is still inengagement with said threaded part. At the outer end of the end portion 23 of the sleeve 10the hole 31 in the end part 23 is widened with a recess 36 so that the head 30 of the screw 3037 can be sunk therein when tightened. The screw head is of the hexagon type but canalso be of another type, such as Allen screw, torque screw, cross groove screw or groove screw.
    Instead of a screw, the screw connection can consist of a coupling part from the pin 2121a projecting threaded rod, which can receive a nut which is tightened at the end part23 outer side when tightening the screw connection.
    The end portion 23 of the arm 10 has a preferably partially conical, towards the partially conicalpart 21a shape corresponding, with bevels provided hole 24. With a pair of simplehand grip allows the adjustment (rotation of the pin 21) to a new positioning positionfor plate 3 is performed.
    The coupling part 21a can be designed in a number of ways which enable shape andforce-coupled coupling with the end part 23 of the arm 10 10. The cross-section of the coupling part 21ashould be uniform with decreasing cross-sectional area seen from the bearing part 21b in order toenable easy adjustment. The cross section can thus be polygonal. Thethe receiving hole 24 preferably has a shape corresponding to the coupling part21a form. However, the shape of the hole 24 need not identically correspond to the coupling part 21aform, as long as a form- and force-bonded connection between them can be achieved indesired number of predetermined positions.
    The method and the tool control device according to the invention are separateconstruction not limited to the i g. 1-5 showed the embodiments, but canmodified within the scope of the appended claims.
