Ridging parts 180°rotation adjustment locking mechanism

Abstract

The 180° rotation adjustment locking mechanism of the ridge building part belongs to the agricultural machinery; on the frame assembly with the main transmission box, the support frame is hinged through the support arm and the sprocket box, and the chute A and the arc guide are set on the support frame The sliding lock block is arranged in the chute A, one end of the connecting rod is hinged with the sprocket box, and the other end is hinged and fitted in the sliding lock block, the hydraulic cylinder A is hinged with the frame assembly and the sprocket box, and the auxiliary The transmission box is rotatably installed on the sprocket box, a chute B is set on the auxiliary transmission box, and the lock pin is fixed, the roller is arranged in the chute B, one end of the heart-shaped rotating bracket is hinged with the support frame, and the other end The hinge is fitted in the center hole of the roller, the hydraulic cylinder B is hinged with the frame assembly and the heart-shaped rotating bracket, the lock pin is fitted in the arc-shaped guide groove, and the lock pin and the sliding lock block are in contact with or out of contact Coordination; this mechanism realizes the 180° horizontal rotation adjustment and automatic locking of the ridge building parts, the structure is novel and reasonable, the locking is reliable, the operation is stable and the 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] The construction of paddy field ridges is an indispensable link in the annual paddy field land preparation. Due to the lack of structural design and defects of the single-side ridge building machine, it is impossible to complete the construction of the paddy field ridges at the corners of the paddy fields, and it is impossible to realize the mechanization of paddy field ridge construction. The remaining part of the ridge still needs to be built manually, which is time-consuming and labor-intensive, and the operation cost is high. In recent years, a mechanism that can be equipped with a single-side ridge-building machine for paddy fields to adjust the rotation of the ridge-building parts has been successfully developed.

[0002] The construction of paddy field ridges is an indispensable link in the annual paddy field land preparation. Due to the lack of structural design and defects of the single-side ridge building machine, it is impossible to complete the construction of the paddy field ridges at the corners of the paddy fields, and it is impossible to realize the mechanization of paddy field ridge construction.

In recent years, a mechanism that can be equipped with a single-side ridge-building machine for paddy fields to adjust the rotation of the ridge-building parts has been successfully developed. The tractor can be used to build the ridge at the corner of the paddy field in reverse, but there are still manual adjustments and locking problems after rotation. Reliability and other issues lead to unstable operation of machines and tools and poor quality of field ridges built
