Problems solved by technology

[0002] The rear suspension of the existing tractor does not have an automatic adjustment balance device. After walking on uneven terrain, when the vehicle body tilts, the agricultural machinery mounted on the rear suspension will also tilt, which is not convenient for operation. If the tilt is large, it may even cause danger , causing inconvenience to people

Abstract

The invention relates to the field of agricultural machinery, in particular to a device for automatically adjusting and balancing tractor rear-suspension through electric control. The device comprises a controller, a parameter input unit used for inputting preset angle values into the controller, a lifting pull rod, a first traction pull rod, a second traction pull rod, a first lifting arm, a second lifting arm, a vehicle body, an electromagnetic directional valve, a horizontal sensor, an oil cylinder and an oil cylinder length sensor, the horizontal sensor is installed in the middle of a rear axle of the vehicle body, the controller controls the oil cylinder to extend and contract by controlling the electromagnetic directional valve, the first traction pull rod and the second traction pull rod are arranged between an agricultural implement and the vehicle body in a symmetrical mode, one end of the oil cylinder is hinged to the second traction pull rod, and the other end of the oil cylinder is hinged to the second lifting arm; the oil cylinder length sensor is installed on the oil cylinder. By means of the device, various agricultural implements can be adapted to travelling on rugged terrain, the reaction is flexible, existing tractor rear suspension needs no great modification, the modification cost is low, and the application scope is wide.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an electronically controlled and automatically adjusted balance device for the rear suspension of a tractor. Background technique [0002] The rear suspension of the existing tractor does not have an automatic adjustment balance device. After walking on uneven terrain, when the vehicle body tilts, the agricultural machinery mounted on the rear suspension will also tilt, which is not convenient for operation. If the tilt is large, it may even cause danger , causing inconvenience to people. Contents of the invention [0003] The purpose of the present invention is to solve the above problems. It provides an electronically controlled automatic balance device for rear suspension of tractors, which can make various agricultural implements adapt to walking on uneven terrain. The reversing valve controls the extension or retraction of the oil cylinder, and the output signal of t...
