Electric suspension control device of tractor

Abstract

The invention relates to an electric suspension control device of a tractor. The electric suspension control device of the tractor comprises a controller, a control panel, a direct-current motor, an angle sensor, a travel switch, a force sensor, a wheel speed sensor, a radar speed measurement sensor, a cylindrical gear reducing mechanism, a worm and gear reducing mechanism, a lifting arm and suspension rod pieces. The controller is installed below an instrument desk and is connected with the control panel, the angle sensor, the travel switch, the force sensor, the wheel speed sensor, the radar speed measurement sensor and the direct-current motor through cables; the direct-current motor is installed on the front side of a lifter shell, a motor shaft is connected with a driving gear shaft of the cylindrical gear reducing mechanism through a spline housing, and the lifting arm is connected with a worm-wheel shaft; the angle sensor is connected with a machine body shell and the worm-wheel shaft through a connecting plate and an elastic coupling respectively; the force sensor is connected with an upper pull rod and a lower pull rod through force measuring pins; the wheel speed sensor is installed on the machine body shell; the radar speed measurement sensor is installed at the front end of the tractor. The electric suspension control device of the tractor has the three control modes of tilling depth control, driving force control and wheelspin control, lifting of farm implements can be intelligently controlled according to soil conditions and actual working conditions, and breakdowns can be diagnosed and monitored in real time. The electric suspension control device of the tractor can be intelligently operated, save labor, save energy and protect the environment.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an electric suspension control device for tractors, in particular to an electric suspension electronic control device for tractors with integrated controls for tillage depth, driving force and slip. Background technique [0002] At present, all tractors adopt hydraulic suspension system, which is composed of hydraulic pump, distributor, oil cylinder, lifting arm, suspension rod and so on. Among them, hydraulic pumps, oil cylinders, and distributors have complex structures, contain many parts, and require high precision. During the working process, the hydraulic system may have valve jamming, safety valve failure, leakage and other faults, which will cause the entire hydraulic lifting suspension system to fail to operate and cannot work normally. In the process of controlling the lifting of the agricultural implements and keeping the agricultural implements suspended at a fixed position,...
