Problems solved by technology
[0002] The walking system of agricultural tractors currently on the market generally adopts mechanical transmission gearboxes and steering mechanisms, but the operation of mechanical transmission gearboxes is complicated and laborious, and tractors need to frequently shift gears and directions during operation to complete a working cycle. Multiple gear shifts and direction changes greatly reduce the operability, flexibility and comfort of the machine, increase the labor intensity of the driver, and reduce the working efficiency

The invention discloses a hydraulic driven remote control tractor. A control system of the tractor adopts a method for controlling a hydraulic motor by combining a singlechip and an electromagnetic valve to realize real-time and flexible control of travel direction and speed of the tractor. Two oil pumps supply hydraulic pressure to a driving hydraulic motor of the tractor and a working hydraulicmotor for driving an agricultural implement respectively so as to solve the problem that a single oil pump supplies insufficient hydraulic pressure to the driving hydraulic motor of the tractor and the working hydraulic motor for driving the agricultural implement.
Description
technical field [0001] The invention relates to a remote-controlled tractor, in particular to a hydraulically driven remote-controlled tractor. Background technique [0002] The walking system of agricultural tractors currently on the market generally adopts mechanical transmission gearboxes and steering mechanisms, but the operation of mechanical transmission gearboxes is complicated and laborious, and tractors need to frequently shift gears and directions during operation to complete a working cycle. Multiple gear shifts and direction changes greatly reduce the operability, flexibility and comfort of the machine, increase the labor intensity of the driver, and reduce the work efficiency. Contents of the invention [0003] The object of the present invention is to provide a hydraulically driven remote-controlled tractor with stepless speed change, flexible operation and high working efficiency. [0004] The technical solution for realizing the above invention is: a hydra...
