Abstract

The invention relates to a Geraeteanlenkung for a rotary plow for connection with a combination for seedbed preparation and sowing. The aim of the invention is to realize the Arbeitsgegege seedbed preparation and sowing in combination with the rotary plow, to avoid complicated and laborious Kopplungsvorgaenge upon rotation of the plow and working direction change and a backward maneuvering possible. According to the invention, the object is achieved in that the telescopic tube connected to the front part of the plow beam and the drawbar of the seedbed preparation device is changed in its length by hydraulic pivoting of the coupling rod. As a result, the caster of the device when turning the rotary plow without decoupling is possible. The chain suspension allows the combination to be reset.

Field of application of the invention

Olo invention relates to a linkage device for connecting and guiding a seedbed overhead line device with sowing device in combination with the rotary plow.

Characteristic of the known technical solutions In the patent literature, numerous, in principle in the constructive interpretation, Combination variants consisting of a rotary plow and devices with tools for seedbed preparation without the Arrangement of Auesaataggrogaten become known. Published is a swivel device in tractor front attachment (DD No. 234348) for a device combination for Seed preparation and sowing, preferably for use with a rotary plow. She fulfills the demands arising from Dor Elneatztechnologle of rotary plow result un! allows at the same time, to achieve a quality seedbed

to classify necessary tools. Compliment ^; Kie coupling operations omitted.

Also known are boom arm (US Pat. No. 3,476,191, DC-GM No. 8314133, DE No. 3419837) on the rotary plow frame, which the Soak the seedbed preparation device to the reversible plow so that it moves when moving the plow in the direction of a Mitnehmerhaken detected and entrained. At the end of the processed strip, the plow can only be turned by a suitable turning operation from the seed bed preparation device

be separated. After turning the plow into the new working position, the hook of the boom can only be coupled to the seedbed preparation device by precise maneuvering of the tractor. That is a major disadvantage of this solution. Such complex coupling maneuvers cost additional time and lift the technology from the point of view

Reversible plow given advantages lower Wendozelten again. As the working direction of seedbed preparation tools

changes the pivoting in the new direction, the use of a sowing device in such a combination is not possible. Another disadvantage is that the agronomically necessary order of

Seedball preparation tools can not be met. Other solutions show the direct connection of seedbed preparation tools via a pivoting device with each Plow body (DE-OS No. 322,216, DE No. 2,605,903, AT No. 374073, SU No. 803880). Here are each plow body Saatbottbereitungswerkzeuge assigned with a working width corresponding to the cutting width of a plow body. The

dai.u necessary holding devices or bearings for seedbed preparation tools mean a high

Mass growth of the plow used in the small number of seedbed preparation tools to be used Improvement of the working effect is not effective, but on the other hand, a high Fertlgungs- and care expenses. The Possibility of combining basic soil cultivation, seed bed management and sowing with the rotary plow Is at this Embodiment difficult to realize. In addition, concepts are known which have flanged parallel to the rotary plow frame a boom

(DE-OS No. 2932824), which allows the classification of seedbed preparation tools. The boom has a carrier spar, on which about a pendulum axis in its longitudinal direction, the seedbed preparation tools are arranged pivotably.

In this solution, the number of tools necessary to achieve a quality seedbed can be classified

become.

Another variant with a cantilever arm for attachment of additional equipment on Drohpflug shows DE-OS Nt. 3414081, where

the work position change does not take place via a catch hook, but by folding over the entire seed bed preparation device upon rotation of the plow. For this purpose, the boom with additional equipment in the direction of travel is folded forward to the plow frame and must then be rotated together with the rotary plow into the new working position.

The attachment of a sowing device is possible in both proposed solutions only with great design effort,

since this must be oscillating and pivotal. The basic mass of the sowing device with seed filling must be carried by the plow frame. There are loads that make a larger dimensions of the plow frame and Dehgelenke required.

Object of the invention The aim of the invention is to realize the operations seedbed preparation and sowing in combination with the rotary plow,

-2 ~ 260 722

whereby complicated and labor-intensive coupling operations on rotation of the plow and at Arbelt6richtungswechsel be avoided and a back maneuver to be possible.

Presentation of the essence of the invention

The object of the invention is to provide a device which allows the coupling of a Saatboubereitungs- and Au88aatkombininnt'on to a Drohpflug, without the turn of the Arbeltsrichtung you reversible plow disconnected device combination decoupled and must be re-coupled.

According to the invention the object is achieved in that a coupling rod mounted hydraulically on the plow blade has a guide element in which a telescopic tube slides. The swiveling articulation of the telescopic tube takes place on the plow frame. At the end of the telescopic tube, the attachment of the pulling device of the seedbed preparation combination takes place. The coupling rod is folded with the help of a hydraulic cylinder counter to the direction of travel to h'nton until it rests on the Grindelhalterungen. In this case, the inner part of the telescopic tube is pulled out, whereby the required length is achieved, which is necessary for the pivoting of Saatbettbereitungskombination behind the rotary plow. After dom plow turning and the entire device for device articulation, the coupling rod can be gobracht using the hydraulic cylinder back to the starting position, whereby dna telescopic tube is retracted.

To connect telescopic tube end and drawbar of Saatbettberoitungskombination 3 chains of appropriate length are arranged in the catfish, that they allow stable backward running when resetting the combination.

Ausführungsbolsplel The invention will be explained with reference to elnos Ausfuhrungsos nfihor. The accompanying drawings show: Flg. Figure 1: Schematic plan view of the attachment for a seedbed well combination in conjunction with anom
