Soil cultivation device

The invention relates to a soil cultivation device in the form of another soil cultivation device that follows or a device that can be attached to a plow, e.g. a combined subsoil packer and soil crusher.

Other tillage implements are often combined with plows, in order to avoid multiple drives over the plowed field as far as possible. Devices used as attachments for plows should be suitable, must not require that they have to be carried by a tractor for their function, such as a Tractor-mounted plow. The devices must therefore be attached devices that do not require any support during work. An example Such a device is the underground packer according to the German utility model specification 1 964 498.

To attached devices via transport routes, which are often also public Roads, to be able to transport, become well-known devices

partly equipped with retractable chassis. An example of this is shown in German patent specification 717 915, according to a Soil crumbler is provided with spiked rollers with three wheels, which after the work of the device in a rest position are pivotable at the top.

It is also known (German Auslegeschrift 1 281 752) on a disc harrow designed as an attachment To attach a drawbar at the end and two running wheels at the other end, whereby these elements are arranged in such a way that that the device in the transport position, in which the drawbar is attached to the tractor, compared to the working position Is rotated 90 °.

In all known devices, considerable physical strength must be expended to move the wheels into their transport position to bring and / or to couple the device to the tractor, since the device must be lifted in any case.

The invention is intended to provide a soil cultivation implement in the form of a trailing implement that can be attached to a plow, e.g. combined underground packers and soil crumbs are designed so that to move the device into the transport position no substantial physical strength has to be expended.

This object is achieved according to the invention in that Connected to the side, front or rear of the device, a coupling (three-point tower) for the three-point linkage of a The lower pivot pin for the tractor is arranged Connection to the lower links and at least one upper pivot point for connection to the upper link of the Has tractor three-point linkage. Advantageously, the overall center of gravity of the device is essentially in the vertical, The central plane of the three-point tower parallel to the direction of travel.

With a construction device or trailer device designed in this way this is coupled to the tractor before transport to or from the field. This can be done using the power lift of the tractor brought the three-point linkage to its lower position after which it can be effortlessly transferred to the follow-up device can be coupled to the three-point tower. The device can now be lifted with the help of the power lift, making it the necessary Maintains ground clearance. After that, the transport is possible. The lifting work is done entirely by the tractor's power lift taken over, so that there is no physical strength of an operator for this must be spent. In view of the often great weight of follow-up devices, this is an essential one Advantage.

Embodiments and developments of the invention are apparent from dependent claims Jlen una c '··> * following description of an embodiment with reference dej. Drawing. Show it:

Pig. 1 is a plan view of a tracking device that is used as combined subsoil packer and soil crumbler is formed,

Pig. 2 is a side view of the device in the direction of arrow II in Pig. 3 and

Pig. 3 shows a further side view in the direction of arrow III in Pig. 2.

The device shown has a frame 1 made of longitudinal spars 2, 3 and transverse bars 4 »5. On the longitudinal bars 2, 3 there are box-shaped housings 6, 7 in which bearings 8, 9 for the Shaft 10 of a packer roller shown in phantom are movable in the vertical direction. Your movement after the top is limited by adjustable stop screws 12. Both sides of the packer roller 11 are in the frame 1 on end shields 13 mounted crumbler rollers 14, the axes of which are parallel to the axis of the packer roller 11.

On the front cross member 4 ″ there are two fastening gvmgsbleche 15 for chains 16, which are connected at 17 miter. ^ K ^ of the links ;, At 17, a pull chain 18 engages. With this chain, the device can be connected to a device, eg Arranged on the rear spar 5 is a catch hook designated as a whole by 19. The catch hook is mounted on a bracket 20 attached to the spar 5 so that it can pivot about a bearing pin 21 attached to the bracket 20. One of the brackets is located on the bracket in both swiveling directions of the catch hook acting leg spring 22 which tries to hold the catch hook 19 in the position shown in Fig. 1. The purpose of the catch hook is that the trailer device which has stopped at the end of a furrow is taken back by the plow when a further furrow starts to be plowed In the plow there is a driver which grasps behind the hook part 23 of the catch hook attention. Only then is the device tightened. If catch hooks are provided, they are naturally on both sides, so on the rear spar 5 as well as on the front spar 4. This is not shown in the drawing to allow two different pulling possibilities (on the spar 4 with a chain and on the spar 5 with a catch hook ) to be able to display. The attachment by means of chains 16, 18 is used when working with a bed plow

Since then there is no change of the working tools of the. _ges (Arn G-egensats to the reversible plow), the device remains permanently connected to the plow, so that only a coupling device is required.

According to the invention, there is a three-point tower 24 on the device. In the illustrated embodiment, the three-point tower attached to the longitudinal spar 3, namely on sheets 25, 25 'welded to the spar · The three-point tower consists essentially from two cranked profile irons 26, 26 ', the lower ends of which are pegs 27? 27 'for connection to the lower links a three-point linkage and their upper ends 28, 28 · run parallel to one another and a distance 29 from one another in which the articulation eye of the upper link of a Three-point linkage can intervene, holes 41a, 41b being provided for inserting a connecting bolt.

A also extends between the parallel parts 28, 28 * Articulation bolt 30 to which a strut, designated as a whole by 31, is articulated. This strut consists of a front one Part 32 and two rear parts 33 »33 ', between which the front part 32 engages and with which this part is connected by screw caps 34.

A second Turin 35 is attached to the bearing housing 6, namely by means of lower screws 36 and a connecting piece 37. At the upper end of the tower 35 is a screw 38 aas the rear end of the strut 31 attached.

At the corner where bars 2 and 5 meet, is on Frame 1 welded a pipe 39, the axis of which is perpendicular. A bolt 40 can be inserted into this tube. The top edge of the tube 39 is slightly lower than the underside of the catch hook 19 so that it can pivot over the tube. When the bolt 40 is inserted into the tube 39, it is sufficient he goes beyond the level of the catch hook, so that the catch hook after pivoting over the tube 39 and inserting the bolt 40 is locked in its pivoted position and thereby with a certain force exerted by the spring 22 is applied to the bolt 40.

While working, the device moves in the direction of arrow F in Fig. 1 or in the opposite direction. The three-point tower 24 has no task while working. When transporting the device, the tractor moves up to it with the device removed so that the three-point linkage of the tractor can be coupled to the three-point tower 24 in the lowered state. The device can then be operated using the power lift .

lifted and transported. Before the transport is the catch hook 19 locked on its locking device as described above in order to prevent the transport width from being too large will. A protruding catch hook would also be a source of danger.

The overall center of gravity S of the device is in the top φ sees seen essentially in the middle of the frame 1. He

lies in the vertical longitudinal center plane, which in Fig. 1 through the dash-dotted line 42 is defined. The distance of the center of gravity S from the three-point tower 24 is smaller than with one Arrangement of the three-point tower on one of the bolts 4 and 5, as the The length L of the device is greater than its width B.

If possible, the arrangement will always be made so that the center of gravity S is as small as possible from the three-point tower 24 has. However, it can be allowed with regard to the permissible

^ - transport width may be necessary to deviate from this rule.
