Steering device for self-propelled sprayer

Abstract

The invention discloses a steering device for a self-propelled sprayer, which belongs to the field of vehicle steering control. The steering device for the self-propelled sprayer comprises an electrical system, a hydraulic system and a limiting device, wherein the electrical system comprises an electromagnetic valve, a three-way twistor switch and a limit switch, and the hydraulic system comprises a hydraulic motor, a hydraulic oil tank, a distribution valve, a steering oil cylinder, a front steering oil cylinder, a hydraulic valve, a lifting oil cylinder, a rear steering oil cylinder and a three-way valve; and the three-way twistor switch is fixed on a machine operation panel, the hydraulic valve is fixed in the middle of a frame and connected with the electromagnetic valve, and the on-off operation of the hydraulic valve is implemented through the control of the three-way twistor switch on the electromagnetic valve. By adopting the structure, the steering device disclosed by the invention has the advantages of small turning radius, easy steering, and capability of realizing lateral movement so as to avoid obstacles.

Description

technical field [0001] The invention relates to the field of vehicle steering control, in particular to a steering device for a self-propelled sprayer. Background technique [0002] The steering device of the vehicle is an important mechanism on the agricultural vehicle. Most of the steering mechanisms of the existing agricultural machinery adopt front wheel steering. Compared with the vehicles driving on the road, the working environment of the machinery for pesticide control is more complicated and diverse. The use of front wheel steering will cause a series of problems such as insufficient steering force, excessive turning radius, and inability to avoid obstacles when encountering obstacles. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a steering device for a self-propelled sprayer that has a smaller turning radius, is easier to turn, and can move sideways to avoid obstacles.
