"Kit for an implement for processing Embankments, roadsides or the like. "

The innovation relates to a kit for a tool for working on slopes and roadsides or the like according to the preamble of the main claim.

Such ground-guided work tools are known and consist, for example, of a mowing device, which is arranged within a housing to which a suction device is connected, so that Immediately transfer the grass mowed by the mower on roadsides, motorways or the like to a transport vehicle can be guided and thus carried away.

The actual working tool is used by the well-known Devices carried by a hydraulically actuated support arm, which may be designed to be multiple articulated and which is placed on a vehicle on which the operator is located, now the position of the support arm according to the desired working conditions for the Working tool adjusts.

Normally the work tool supports itself via a roller or the like on the ground. To be able to work on small bumps in the ground, it is thus required for the operator operating the tool, the main support arm constantly accordingly track the ground conditions in order to prevent the implement suddenly free

hangs floating in the air. In many cases, this tracking is not possible at all because of the uneven ground hidden by the grass to be mowed.

The innovation is based on the task of creating the generic To improve the kit for an implement so that the implement is automatic adapts to the soil conditions.

This is the task underlying the innovation solved by the teaching of the main claim.

By using the parallelogram linkage an always ground-parallel position of the underside of the Working tool guaranteed.

Through the use of the hydraulic piston-cylinder arrangement several functions of the parallelogram linkage are possible. Will the hydraulic piston-cylinder assembly set to a "floating position", the parallelogram can work freely and the work tool can, for example, the uneven ground follow. The hydraulic piston-cylinder arrangement, however, also allows the parallelogram linkage are stiffened so that proper movements of this parallelogram linkage are not possible. This is important, for example, in the transport position of the implement, so that it is spatially very tight of the parallelogram linkage folded up can be. Finally, by controlling the hydraulic piston cylinder arrangement, it is possible also to lift the parallelogram linkage and thus to lift the work tool without the support arm, who carries the work tool, must be moved.

This is useful in many cases, because here the smaller lifting movement is difficult to carry out at the workplace.

Finally, according to the innovation, it is also possible to adjust the inclination of the bottom side of the implement. These multiple advantages are achieved through the use of the novel arrangement.

An embodiment of the innovation is shown below described with reference to the drawing.

In the drawing, 1 denotes a working tool, formed for example by a housing in which there is a mowing device, with a suction opening 2 connected to the housing, to which the suction hose can be attached. The work tool is guided over a roller 3 on the ground.

The connection of the work tool to the support arm, not shown in the drawing, of the actual work vehicle is carried Via a support arm connection 4, which is shown in the drawing as a cylinder pin, to which the sleeve-shaped connecting device 5 are placed can, with the gripping device of the support arm now being attached to a corresponding gripping device connects.

Between the support arm connection 4 and the actual Working tool 1 is a handlebar parallelogram switched on, that consists of two upper links 7, two lower links 8, two front wishbones 9 and two rear wishbones 10 consists, the two

s' rear wishbone 10 by a working tool-

own Konstrukti onstei1 are formed. The axis of the rear wishbones 10 runs between the pivot points 11 and 12.

As usual with the parallelograms, close the individual handlebars are articulated to one another.

The two front wishbones 9 are formed by a work shield 14 that holds the two wishbones j connects and the center back a connection

device 15 carries to which the support arm connection 4 connects.

On top of the housing of the working tool 1 is a hydraulic piston cylinder assembly 16 arranged, which connects to the underside of the support arm connection 4 and with which a stiffening of the parallelogram at any desired altitude

of the parallelogram or any desired extension of the parallelogram is possible. In the Float position of this hydraulic piston-cylinder arrangement the parallelogram is completely free. The rigidification of the mobility of the parallel

gramms is particularly important for the transport position.

A transverse axis 17, which is a spindle adjusting device, engages the shields 15 that can be seen in the drawing 18 carries, which in turn engages other encles on the support arm connection 4. Through this inclinations of the support arm connection with respect to the work shield 14 are possible.
