Abstract

The invention belongs to the field of agricultural machines, and relates to an electro-hydraulic hanging field end self-adaptive lifting device for a tractor, and a control method. The self-adaptive lifting device includes a turning monitoring module, a control module, and a hydraulic execution module; the turning monitoring module can recognize the speed of a left driving wheel and a right left driving wheel and the turning angle of a turning wheel, and can send a monitored signal to a controller; the control module can determine the turning time of the tractor at a field end according to the received speed of the left driving wheel and the right left driving wheel, and the recieved turning angle signal of the turning wheel, and the controller can send a command to an electro-hydraulic proportional valve and a reversing valve so as to control lifting of a hanging system; the hydraulic execution module can achieve lifting and falling of the hanging system according to the command of the controller, can keep a farm implement at a certain working position; and a hydraulic system can timely supply flow to a hydraulic cylinder through a one-way valve when the farm implement rapidly falls down, and cavitation can be avoided. Compared with the prior art, the electro-hydraulic hanging field end self-adaptive lifting device is high in automatic level, is simple to operate, and can greatly reduce the labor cost.

Description

Technical field [0001] The invention belongs to the field of agricultural machinery research, and specifically relates to an adaptive lifting device and a control method for a tractor electro-hydraulic suspension field head. Background technique [0002] Agriculture is the foundation of the national economy, and agricultural mechanization is a symbol of a country's modernization. Developed countries have realized agricultural modernization as early as the middle of the last century, while the level of agricultural modernization in my country is still relatively low. Nowadays, with the advent of informatization, many emerging technologies are applied to agricultural mechanization, which has taken a big step forward in the direction of intelligent and automated agricultural machinery. The tractor is the main power component of agricultural mechanization. It can be combined with farm tools to form a working machine to complete field operations. With the development of information ...
