METHOD OF ADJUSTMENT OF THRESHING GAP IN THRESHING-SEPARATING DEVICE OF ROTARY TYPE WITH ROTATING DECK AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC A01F12/28 

FIELD: agriculture.

SUBSTANCE: inventions can be used in threshing-separating device (TSD) of rotary type with rotating deck to adjust the threshing gap. The method of adjusting the threshing gap lies in setting of the necessary gap by pressing the key on the control unit of the harvester. This operation is implemented by insertion into TSD of additional elements, which are used as a feeler and a torsion bar with a carrier rigidly connected to it. Using the feeler the change in torsion angle is provided. Change in the threshing gap is carried out by moving the replacement decks by the torsion. The gap adjustment is carried out simultaneously in all areas of pinching the processed product. The device for adjustment of the gap comprises a rotating deck and torsion shafts mechanically connected to it. The deck feeler is rigidly connected to the rotating deck. The locking device, the feeler of position and the feeler of adjustment mechanism of the threshing gap are rigidly interconnected and rest through the slides on the sliding surface of the rotating deck. The sensors of assessment of the gap width and the carrier are rigidly connected to the torsion shafts. On the rotating deck the replacement decks and springs are located, and articulately connected with it.

EFFECT: increased production rate of the harvester and reduction of labour intensity of the service.
