" Adjustment device for the multi-part adjustment screen (cleaning screen) of a combine harvester"

Utility model registration

In the case of multi-part adjustment sieves (cleaning sieves), the adjustment of the lamellae causes particular difficulties in that the rear screen part, which is adjustable in height, provides access to the adjustment device of the upstream adjustment screen blocked. For the precise adjustment of the lamellas of the front screen part, the rear part had to be used in the known designs Sieve part folded up and the one at the end of the sieve surfaces Wind deflector can be removed, resulting in a great loss of time and an additional burden on the operating personnel arises. After the sieve adjustment during operation q.3 Combine harvester takes place, the operating personnel is particularly annoyed by the occurrence of dust and chaff. i

The task of the innovation is to simplify the adjustment device, by adjusting the i Lamellae of both parts of the seal can be made.

According to the present innovation, the object is achieved by I.

that ar. End piece of the rear sieve part an adjusting bridge to ';

is brought, in which an operating lever is guided, the ■ in connection with an adjustment device known per se

which is attached to the end of the front sieve part una allows the slat adjustment.

The operating lever can be connected to a clamping device are brought, which is influenced by compression springs, so that the operating lever is self-locking in the adjustment bridge to be led.

Alternatively, a leaf spring can also be built into the adjustment bridge for the same purpose.

For tension-free adjustment of the front screen part, the actuating lever is subdivided, with a compression spring Compensation for the changed altitude when swiveling up the rear sieve part guaranteed as a flexible link.

The front part of the actuating lever carries a stop on both sides to keep both parts of the actuating lever in its extended position ^ d hold.

After both the handle of the adjustment device for the rear screen part and the handle of the actuating lever for the front screen part protrudes beyond the end of the entire screen surface, the lamellae can be adjusted easily and without significant expenditure of time.

In the drawing, the subject of the application is, as far as it is necessary for understanding the innovation, in Figures 1 to 3 shown as a non-limiting embodiment.

It shows: Fig. 1 the cleaning box with the multi-part

In the cleaning box 1 of a combine harvester, not shown, there is the multi-part adjustment screen (cleaning screen), consisting of the front screen part 2, which is rigidly built into the frame of the cleaning box 1, and the height-adjustable rear screen part 4, which is articulated via hinges 3 and which is located in a slot guide 5 of the side walls of the cleaning box 1 can be locked in the desired position using any clamps. The arranged at the front screening member 2, known per se adjusting device 6 is contacted with a multi-part operating lever 7 in conjunction, the, comparable in the adjustment bridge 8 which is fixed to the rear screen part ¹ I

Slidably guided Viird and by means of a spring-loaded clamping device 9 is locked in a self-locking manner. The handle of the operating lever 7 protrudes over the rear end of the rear Sieve part 4 also. For proper adjustment of the front screen part 2, the operating lever 7 is divided, wherein a compression spring Io to compensate for the changed altitude when pivoting up the rear screen part 4 as yielding link guaranteed. When adjusting the operating lever 7, the position of the slats of the front screen part 2 reached during the adjustment of the rear Siebtiäles 4 takes place by actuating the adjusting device 11.
