Control system and harvester with same

Abstract

The invention provides a control system and a harvester with the control system. The control system comprises a valve body, a working oil cylinder, a three-position four-way valve, a first hydraulic control valve and a second hydraulic control valve, a piston of the working oil cylinder divides a working cavity of the working oil cylinder into a first working cavity and a second working cavity, the first working cavity communicates with a first working oil port in the valve body, the second working cavity communicates with a second working oil port in the valve body; the three-position four-way valve is connected with the valve body and communicates with a containing cavity of the valve body; part of the first hydraulic control valve is arranged in the containing cavity and is connected with the three-position four-way valve; and the second hydraulic control valve and the first hydraulic control valve are arranged in a spaced mode, and part of the second hydraulic control valve is arranged in the containing cavity and connected with the three-position four-way valve. The control system and the harvester with the control system solves the problems that in the prior art, an electriccontrol valve assembly in a harvester is assembled in a stacked mode, so that the overall size of the electric control valve assembly is large, large installation space is occupied, and the phenomenaof oil leakage and oil seepage are likely to happen.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a control system and a harvester with the same. Background technique [0002] In the prior art, the electric control valve assembly in the harvester is assembled in a stacked manner, that is, the hydraulic control check valve is connected to the valve body through the bolts on the three-position four-way valve, so that the electric control valve assembly is in the form of a valve body. , hydraulic control check valve and three-position four-way valve are stacked and assembled sequentially, resulting in a large overall volume of the electric control valve assembly and occupying a large installation space, and because the hydraulic control check valve and the three-position four-way valve The connection position of the valve is located outside the valve body, which is prone to oil leakage and oil leakage. Contents of the invention [0003] The main purpose of the ...

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to provide a control system and a harvester with it, so as to solve the problem that the electric control valve components in the harvester in the prior art are assembled in a stacked manner, resulting in a relatively small overall volume of the electric control valve components. It is large and takes up a large installation space, and because the connection between the hydraulic control check valve and the three-position four-way valve is located outside the valve body, it is prone to oil leakage and oil leakage
