The fast switching mechanism between the forward and reverse operation states of the single-sided ridge building machine belongs to agricultural machinery; on the suspension frame assembly with the main transmission box, the connecting frame is hinged through the supporting swing arm and the supporting link, and the servo electric cylinder and the suspension frame are hinged. The assembly is hinged with the support swing arm, the main transmission case PTO is hinged with the support swing arm, the sprocket A is installed on the main transmission case PTO shaft, the S-shaped chute is set on the support swing arm, and the rollers are fitted on the S. In the chute, the auxiliary transmission box is rotatably installed on the lower part of the supporting swing arm. One end of the connecting rod A is hinged with the connecting frame, and the other end is hinged and fitted in the center hole of the roller. The connecting rod B is connected to the connecting rod A and the auxiliary The transmission case is hinged, the power input shaft of the auxiliary transmission case is hinged with the supporting swing arm, the sprocket B is installed on the power input shaft of the auxiliary transmission case, and the sprocket A and the sprocket B are connected by a chain; The parts are offset, rotated and locked in one step, the structure is novel and reasonable, the operation is simple, and the rotation adjustment efficiency is high.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an operation tool for building paddy field ridges. Background technique [0002] Paddy field ridge building is an indispensable link in the annual paddy field land preparation. When the tractor is attached to the ridge-building machine, the ridge-building machine cannot build the ridge at the corner of the paddy field due to the distance occupied by the tractor body. In recent years, a mechanism that can be equipped on a paddy field single-side ridge-building machine to adjust the rotation of the ridge-building parts has been successfully developed, and the tractor can be used to build the ridges at the corners of the paddy fields in reverse. However, due to the deficiencies and defects in the structural design of the existing single-side ridge building machine for paddy fields, it is necessary to use two hydraulic cylinders to adjust the left and right offset and 180° rotation of ...
