Steering detection and measurement mechanism for automatic driving agricultural machine

Abstract

The invention provides a steering detection and measurement mechanism for an automatic driving agricultural machine and relates to the technical field of automatic driving agricultural machines. Whenan existing steering detection mechanism of an automatic driving agricultural machine is used, a measured structure moves, self-adaptive automatic adjustment cannot be conducted according to the moving direction of the measured structure, and the detection mechanism and vehicle accessories are prone to being damaged in a detection process. With the steering detection and measurement mechanism adopted, the above problems can be solved. The steering detection and measurement mechanism comprises a main body, stress grooves and a moving part; the main body is of a rectangular plate-shaped structure; the top end of the main body is connected with a vehicle body through bolts; the stress grooves are formed in the corners of the main body; the moving part is arranged at the bottom of the main body; the moving part can be movably connected with the main body and can also be movably connected with a connecting part while being connected with the main body, so that the mechanism can move in a self-adaptive mode in a front-back direction and a left-right direction; the mechanism can better adapt to different moving angles of a front shaft when being connected with the front shaft to detect the front shaft, and therefore the front shaft is prevented from being damaged.

Description

technical field [0001] The invention belongs to the technical field of automatic driving agricultural machinery, and more specifically relates to a steering detection and measuring mechanism for automatic driving agricultural machinery. Background technique [0002] In the agricultural machinery automatic navigation driving system, the angular displacement sensor is used to sense the left and right side turning angles of the agricultural machinery driving at high speed. It is one of the key equipment of the agricultural machinery automatic navigation driving system. When the agricultural machinery is turning, the front axle is usually used to control the wheel steering . [0003] For example, the application number: CN201610793477.9 relates to a steering angle measuring device, including the steering angle measuring device including an angular displacement sensor fixed on the body of the agricultural machine, and the input shaft of the angular displacement sensor is located ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a steering detection and measurement mechanism for automatic driving agricultural machinery to solve the problem that the existing automatic driving agricultural machinery steering detection mechanism cannot move according to the displacement of the measured structure when the existing automatic driving agricultural machinery is in use. Self-adaptive and automatic adjustment of the direction will easily cause damage to the detection mechanism and vehicle accessories during detection, and after a long period of use of the existing automatic driving agricultural machinery steering detection mechanism, the connection between the detection mechanism and the front axle is prone to slipping, resulting in The problem of inaccurate detection data
