"Adjustment device for cleaning sieves on combine harvesters"

Utility model - registration

The innovation relates to an adjustment device for cleaning sieves on combine harvesters.

In the case of cleaning sieves on combine harvesters, it is known to use the lamellae to change the adjustment screen in their position. The adjustment device used is below the straw walker on the lower part of the cleaning screen attached. An actuation of the adjustment device is therefore only possible by means of an operator from the interior of the combine harvester housing. At the same time, one must known adjustment before operation, the cleaning flap, which is assigned to the cleaning sieve, can be removed. As a result The dust that arises during the combine harvester makes it difficult to operate the adjustment device, thus providing the necessary sieve regulation is neglected in most cases during the combine.

According to the present firing, the flat parts used in the known Executions occur to be avoided.

To this end, it is suggested through the side wall of the combine to drive a connecting element to the adjusting device in such a way that this is both the adjustment and the locking the selected position of the slats.

The connecting element can consist of one in the side wall of the Ilähdrescners mounted, axially displaceable guide tube, which

articulated at its end piece with the adjusting lever of the toothed segment is connected and thereby simultaneously receives its second support, an actuating rod adjustable in length in the guide tube is performed, which is in engagement with the spring-loaded locking lever.

The actuation of the adjustment device is achieved by by pulling out the operating rod to the side of the locking lever the toothed segment is lifted and the adjustment lever is rotated about its bearing point by moving the guide tube on the handle, whereby the slats can be raised and lowered in their angular position via the adjustment linkage. When releasing the operating rod the spring-loaded locking lever engages in the toothing of the toothed segment and the selected setting is activated thereby locked.

The same effect can be achieved by using the operating rod and the guide tube are arranged side by side and the locking lever is actuated via an angle lever.

In order to be able to recognize the selected slat setting from the outside, a scale is attached to the guide tube on which the set Slat angle can be read.

It should be part of the innovation to make the guide tube in several parts by the end piece is articulated with a pull or lifting strap that receives a guide slot in which both the locking lever and the adjusting lever connected to a double angle lever slides in bolts.

The subject of the registration is on the drawings insofar as it is for the Understanding the innovation is necessary, shown in Figures 1 to 6 as a non-limiting embodiment.

On the side wall 1 of a combine press, the guide tube 3 is mounted axially displaceably in the bearing 2 and can be operated on the handle 4. The guide tube 3 is connected in an articulated manner to the adjusting lever 5 at its end opposite the handle A. In the guide tube 3, the actuating rod 6 is arranged to be longitudinally displaceable and is connected to the detent lever 8 in an articulated manner opposite its detent handle piece 7. The articulated connection can be made by bending the actuating rod 6, which engages in a slot guide 9 of the locking lever 3. The actuation of the adjustment device is achieved in that the locking lever 8 is lifted out of the toothed segment Io by pulling out the actuating rod 6 to the side and by moving the guide tube 3 on the handle piece A, the adjustment lever 5 rotates around its bearing point, whereby the Frame linkage 12, the slats 13 can be raised and lowered in their angular position. When the actuating rod 6 is released, the locking lever 8, which is under the action of the tension spring Ik , latches into the toothing of the toothed segment Io and the selected setting is thereby locked, as shown in FIGS. 1, 2 and 3.

The same effect can be achieved by removing the operating rod 6 and the guide tube 3 are arranged side by side and via an angle lever 15 the actuation of the locking lever 8 takes place. In order to be able to recognize the selected setting of the slats 13 from the outside, i.e. on the outer wall of the combine harvester, a scale Ib is attached to the guide tube 3, on which the set slat angle can be read. For improvement the locking of the adjusted slats 13 can also be done by the guide tube 3 are divided and the end of the same equipped with a pulling or lifting strap 17 v / earth, the pulling or lifting strap a Führunpsschiltζ 18 carries, in which both the locking lever 8 as the adjusting lever 5 connected to a double angle lever 19 also slides in bolts 2o.
