Steering adjustment mechanism for ridge building component of paddy field ridge building machine

Abstract

The invention provides a steering adjustment mechanism for a ridge building component of a paddy field ridge building machine, and belongs to agricultural machines. A main drive box body is fixedly installed on a parallel four-bar suspension frame. A rotating arm plate is hinged to the main drive box body, wherein a sprocket drive box body is fixedly installed on the rotating arm plate. The two ends of a bi-directional hydraulic oil cylinder are hinged to the parallel four-bar suspension frame and the rotating arm plate respectively. A power output drive box body is fixedly installed on the lower side of the rotating arm plate. A power input shaft, a shaft I, a first bevel gear and a second bevel gear are installed inside the main drive box body. A driving sprocket, a chain and a driven sprocket are installed inside the sprocket drive box body. A shaft II, a third bevel gear, a fourth bevel gear and a power output shaft are installed inside the power output drive box body. A power output sprocket is fixedly installed on the outer side end of the power output shaft. The steering adjustment mechanism realizes 180-degree rotation of the ridge building component on the single-side paddy field ridge building machine, completes mechanical work on a ridge at the edge of a paddy field, and is reasonable in structural design, convenient to adjust, high in work efficiency, low in operation labor intensity and reliable in use.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a steering adjustment mechanism of a ridge-building operation part of a paddy field ridge-building machine. Background technique [0002] Ridge building is a paddy field land preparation operation in the rice production process and is an important link in the mechanization of rice production. At present, paddy field ridges in my country are mainly built manually, and paddy field ridge building is a heavy and labor-intensive labor. Artificial ridge building has the disadvantages of high labor intensity, low efficiency, and high cost. In recent years, with the development of rice production mechanization, researches on paddy field ridge building machines have been carried out at home and abroad, and different types of machines have been produced, including single-side ridge building machines. During operation, the single-side ridge-building machine is pulled by a tractor, but because...

AI Technical Summary

Problems solved by technology

During operation, the single-side ridge-building machine is pulled by a tractor, but because the paddy field of its ridge-building parts occupies a large space, it is blocked by the front tractor when it travels to the head of the field, and it is impossible to build a right-angled ridge when the head of the field turns. It is also impossible to reverse the ridge

As a result, manpower is still required to build ridges at the corners of the land, and it is impossible to fully realize the mechanized operation of ridge building
