    15 20 25 30 35 a smooth ride. To some extent, this is also linked to the degree of cupping of the plate.
    Problem The object of the present invention is to provide a method and a tool control device for an agricultural implement of the type mentioned in the introduction, which solve the above-mentioned problems.
    Brief description of the invention The object is achieved with a method and a tool control device in an agricultural implement, which device has been given those of claims 1 and 2, respectively. 6 characteristic features.
    Preferred embodiments of the implement control device according to the invention have been given the features set forth in the subclaims.
    If you provide the hubs of the plates with a shaft that is angled a few degrees and at the same time arrange so that it can be rotated and locked in different positions, you get an adjustable plate angle. The possible setting angle variation will be the double bending angle of the pin. This is known per se, e.g. through prototypes manufactured. However, only this solution is not complete as it is very difficult to turn the pin after a period of use as soil, dirt and rust cause the shaft to jam in the sleeve. The improved solution according to the invention means that the pin is made conical and that it is given a controlled opportunity to be displaced outwards during adjustment. The adjustment then becomes very simple and can be done with a few simple steps. It makes it easier to use a tool. This tool is inserted into a hole in the pin, as this tool has a milled surface, the pin can be displaced outwards a few mm, which is sufficient for the pin to be able to be rotated easily. When the correct position has been reached, the tool can be turned and the pin retracted into the correct position and can then be locked in position with a pin, which itself is locked with a rubber strap or in another known manner.
    In this way, the plate can be provided with an adjustability which has only a marginal cost impact and is durable and maintenance-free. This solution means that one and the 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 dressing can be made short and compact to facilitate the passage of straw words and plant residues. The cone shape means that the axial force absorbed by the bearing acts in the direction of pushing the pin into the cone-shaped hole, which in turn contributes to a stable joint.
    Brief Description of the Drawings The invention is described in more detail below with reference to the accompanying drawings, which show a preferred embodiment.
    Fig. 1 shows a perspective view from above of an agricultural implement in a working position with an implement control device according to the invention.

    Fig. 5 shows a perspective view of a tool.
    Fig. 6 shows a cross section through the implement control device according to Fig. 4.
    Description of a Preferred Embodiment I f1g. 1 - 6, a preferred embodiment of a tool control device in an agricultural implement 1 for tillage is illustrated.
    Fig. 1 shows the agricultural implement 1 in a working position. The agricultural implement 1 has a frame 2 and a towing device 2a, which is suitably connectable to and can be towed by a tractor (not shown). The machine 1 here comprises three rows a, b, c implements in the form of two front rows a, bj word processing, free-rotating, discs 3 and a rear row c with roller assembly 4. The discs 3 in one of the two rows a, b are turn in the opposite direction compared to the plates in the second row b resp. c. In a known manner, rows a and b with plates 3 and row c with roller assemblies 4 are divided into three sections 5, 6 and 7, the outer sections 5 and 7 of which are connected to the outer sections of the plate and roller sections. The transport wheels 8, which are mounted on the outer rail sections 5 and 7, are rotatable together with the frame sections 5-7 by means of hydraulic pistons 9 to a transport position for agricultural implements 1.
    Fig. 2 shows that the plates 3 in the two rows a and b are freely stored at the bottom of the arms 10 and stored suspended in transverse beams 11 and 12 by means of bearing devices 13 connected by welding or casting (see description with reference to fi (3). Between the beams 11 and 12, bulkheads 14 are arranged.
    Fig. 3 shows on a larger scale the suspension and storage of the plates 3. Each plate 3 is consequently fixed to a hub 20, which is freely mounted around an adjustable, conical part 21a arranged at the lower end of the arm 10. of a pin 21. The conical part 21a has a conicity of oi degrees (see fi g. 6). 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 consists in a known manner of two storage halves 14 and 15, the lower storage half 14 being connected to the arm 10 and the upper storage half 15 being fastened to the lower storage half 14 by means of a screw / nut connection 16.
    The beams 11 and 12 (see Fig. 2) run through the bearing member 13 and four rubber rods 17 are placed between the beams 11 and 12 and the respective bearing halves 14, 15.
    The plates 3 are suitably screwed to the hub 20 by means of a screw / nut connection 18.
    Figs. 4-6 show in more detail the method according to the invention for changing the setting of a tool as well as a tool control device and a tool according to the invention for carrying out the method.
    The pin 21, which is rotatably mounted in a bearing 20a in the hub 20, is angled a few degrees ß according to Fig. 6 between the conical part 21a and the circular-cylindrical part 2lb present in the bearing. The pin 21 can be rotated and locked between positions, so that an adjustable plate angle is obtained. In Fig. 6, the angle between the conical part 21a and the straight part 21b of the pin is an angle ß shown in a first outer position. According to the invention, when the conical part 21a of the pin is rotated 180 degrees in the hole 24 in the sleeve to its second outer position, this means that the plate angle relative to the conical part 21a has changed 2ß relative to the first outer position. In the case shown, ß can be approx. 2 degrees and 2ß consequently be approx. 4 degrees. Other desired modes are of course also possible within the scope of the claims.
    In addition, by making the outer end portion 21a of the pin 21 outside a shoulder 22 extending along the ony circle conical with a predetermined conicity, it is given a controlled possibility of being displaced outwards during the adjustment. The cylindrical end part 23 of the hearth 10 has a conformed hole 24 corresponding to the end of the end part 21a. With a couple of simple handles this adjustment can be carried out. Then the pin jammed due to. the environment in which the implement is used, a slight hammer blow to the outer end surface of the pin 21 may be required to release it from the cylindrical end portion 23. The pin 21 is provided with a predetermined number of positioning holes 25 along its onyx circuit. Advantageously, the holes 25 may consist of a number of continuous, intersecting bores through the pin 21. In a preferred embodiment, two such bores 10 are arranged perpendicular to each other, which means four positioning holes 25 at equal distances from each other along the circumference of the pin 21.
    To facilitate the rotation of the pin 21 when changing the position of the pin 21, a tool 26 can be inserted into a hole 27 at the outer end of the pin 21. The tool 26 has a holder part 31 and an elongate round bar part 32, which at its end facing away from the holder part has a chamfered part 33 and is at the side of the chamfered part 33 facing the holder part 31 provided with a lug 34, which in the circumferential direction is approx. 90 degrees offset relative to the chamfered surface 33 of the chamfered portion 33. The lug 34 forms a lever when rotating the tool 26. Because the tool 26 has provided with the chamfered part 33, when the tool 26 is chamfered so that the chamfered surface of the chamfered part 33 is directed towards the arm 10, it can be displaced outwards a few mm, preferably ca. 1.5-2 mm, which is sufficient for the pin 21 to be able to be turned easily to a new desired position. When the correct position has been reached, the tool 26 can consequently be rotated so that the pin 21 is clamped back to its original position in the conformed hole 24 in the arm 10 and the plate 3 has been changed to the desired angular position. Then a locking pin 29 is inserted into the intended positioning hole 25 and the plate 3 is locked in the selected working position. The pin 29 can then advantageously be held in its locked position by means of a rubber strap 30 or in another known manner.
    The method and the tool control device according to the invention are not limited in their construction to that in FIG. 1 - 6, but can be modified within the scope of the appended claims.
