Abstract

The invention relates to an electro-hydraulic control system of a hydraulic steering micro-tillage machine in a mulberry field. By using a navigation location system, the geographical location information of the mulberry field and the real-time position and course information of the micro-tillage machine in the operation process are obtained; by comparing the actual path of agricultural machinerywith a predefined path, the expected deflection angle of an agricultural machinery vehicle is figured out and transmitted to a steering control system module; the steering control system module controls a three-unit four-passage electro-hydraulic proportion flux valve to achieve the piston rod displacement of a left hydraulic cylinder and a right hydraulic cylinder, and therefore steering is achieved through differential running of a left wheel and a right wheel; the arrangement of a hydraulic pipeline ensures the independent and fast response of the left and right hydraulic cylinders which cannot affect each other and can control the left and right wheels of the micro-tillage machine respectively; meanwhile, the switchover of a main pipeline is achieved through a total electromagnetic valve, so that the system is very efficient and reliable.

Description

technical field

[0001] The invention relates to the technical field of control of a hydraulic steering tiller for mulberry gardens, in particular to an electromechanical-hydraulic control system and method for a hydraulic steering tiller for mulberry gardens. Background technique

[0002] In my country's agricultural production, sericulture production has a long history. In recent years, with the continuous progress of my country's scientific and technological level, agricultural mechanization has been greatly developed, and the performance of agricultural machinery for field operations is particularly prominent, but the development of mulberry garden management machinery is still in its infancy. The current management of mulberry gardens is mainly based on manual operations, which directly increases the cost of sericulture management.

[0003] In the process of mulberry field operation, the requirements for the operation speed, width, quality and flexibility of mulberry fi...
