Description

Connecting rod type steering adjusting device of bidirectional disc plow Technical Field The utility model relates to the technical field of disc plows, in particular to a connecting rod type steering adjusting device of a bidirectional disc plow. Background The disc plow is used as an important tool for modern agricultural cultivation, and the steering adjustment performance of the disc plow directly influences the working efficiency and the soil treatment quality. The traditional bidirectional disc plow mostly adopts gear transmission or hydraulic drive to realize steering adjustment, and has the problems of complex structure, lagging operation response, high maintenance cost and the like. For example, some existing devices directly connect a plow frame and a steering mechanism through a rigid connecting rod, so that the defects of limited steering angle, poor synchronism, deviated cultivation track and the like are caused, and the existing devices are difficult to adapt to the operation requirements of complex terrains. Although the existing bidirectional disc plow adopts a hydraulic drive or mechanical connecting rod structure to realize steering adjustment, the following technical defects still exist: 1. The existing hydraulic steering system is required to be provided with complex hydraulic components such as an oil pump and a pipeline, and the problems of oil leakage, blockage and the like are easy to occur under the field bad working conditions, so that the adjustment requirements of different soil conditions are difficult to adapt; 2. The problem of low adjustment freedom degree generally exists in the conventional mechanical connecting rod structure, and the steering rod and the adjusting rod adopt a single hinge mode, so that the angle adjustment range of the disc plow is limited, and the quick switching during bidirectional symmetrical cultivation cannot be realized; 3. The prior regulating device generally lacks a synchronous temperature structure, and lacks effective support between a steering shaft and a connecting rod, so that mechanical vibration is easy to generate during high-speed cultivation, and uneven soil penetration depth of a plow body is caused, thereby affecting cultivation quality.
