Description

Subject of the invention

Of the The invention relates to a tractor mulching accessory, the accessory for arranging on a tractor through a standard three-point connection on the rear part of the tractor is provided.

Technical problem

The solved by the present invention technical problem lies in how to design such a tractor mulching accessory is, in a certain range, a continuous arrangement allow the mulching accessories across the mulch vehicle movement is used to mulch the inclination of the cultivating Terrain with regard to the level drivable by the tractor adapt and at the same time a manual adjustment of one though Automatic cam safety of the mulching accessory when pushing to allow for an obstacle.

State of the art

From the patent specification SI 20711 (BMK Engineering doo) is such a tractor mulching accessories known. There has been a need for a larger bank of mulching equipment on a standard tractor accessory due to the grass cutting of the road bank, in Weingarten u. Ä. Proven. The cited application of this mulching accessory dictated the development of such an accessory with a built-in cam lock that would allow for automatic removal from an obstacle, e.g. As stems, stones, bollards u. would allow.

Solution of the technical problem

The illustrated technical problem is caused by the invention Solved accessory, which is characterized that a hydraulic piston used to rotate the mulching accessory around the longitudinal drive shaft, preferably a propeller shaft, on a hinge is suspended, which it with a parallelogram-shaped Console connects that are not on a standard three-pin tractor accessory is suspended, by two arches, which together form an approximately full angle and in the transverse direction so offset, that between their neighboring ends an ear the hydraulic piston is stored while the second Ear the same hydraulic piston on a mulching accessory housing is stored. Such a suspension offers a greater unrestrained Rotation of the mulching accessories as the known such Mulch accessories. The mentioned parallelogram-shaped Console is designed with a longitudinal leg in telescopic channel, in such a way that this leg in the working position in its shortest Stand is present and retained in this state by a spring becomes. When the mulching accessory hits an obstacle, the telescopic leg automatically pulls out, the mulching accessories stands diagonally on the tractor axle and with his so deformed parallelogram-shaped console the obstacle without mutual damage.

The Features of the inventive accessory will be continued in the description of an embodiment and drawings in more detail. The drawings show:

1 Top view of the accessory according to the invention in a schematic view,

2 Cross section of the same along the line II-II 1

The tractor mulching accessory is made of a standard triangle accessory 1 , which is attached in three points to the tractor part, not shown on the drawings, executed.

On the accessories 1 in the area of the drive shaft 2 , which is attached on the one hand in not shown on the drawings Traktorabtrieb is a hinge 3 a parallelogram-shaped console 4 executed. A longitudinal leg 5 this console 4 is stiff, the other thigh 6 is extensible in the longitudinal direction, wherein at least one spring 7 kept in the shortest condition. The feathers 7 are preferably helical spring and in ears 8th on every part of the thigh 6 clamped with one end each. The number of springs 7 can be arbitrarily changed manually on the site and thereby the operation of the inventive accessories are adapted to the current terrain requirements.

Both thighs 5 and 6 the parallelogram-shaped console 4 are with an actuator 9 , preferably a hydraulic cylinder, connected together. This offsets the mulching accessories transversely with respect to the tractor and adjusts the operation of the equipment to current conditions.

At the other end is the parallelogram shaped console 4 in a hub 10 the drive shaft 2 stored. On the hub 10 is the mulching equipment from the back 11 , On the hub 10 is also a pair of arcuate holder 12 appropriate. The holders 12 run at a distance and parallel to each other. At the free ends of the holder 12 is an actuator 13 , preferably a hydraulic cylinder, which is the mulching accessory 11 around the longitudinal axis of the drive shaft 2 turns, stored. The actuator 13 is at the other end in the mulching accessories 11 stored. The cited storage of the actuator 13 allows rotation of the mulching accessory 11 to the Axis of the shaft 2 in the range above 90 °.

Of course can be selected by professionals from the field of invention Other embodiments are conceived without being the news and in the appended claims Deviate invention features.
