Abstract

The invention relates to the field of automatic control of agricultural machinery, and especially relates to an electric automatic steering system for the agricultural machinery. The electric automatic steering system for the agricultural machinery comprises an automatic steering device. The automatic steering device comprises a steering control, a planetary gear reduction mechanism and a disk brushless motor which are coaxially arranged in sequence. The planetary gear reduction mechanism and the disk brushless motor are arranged in a casing. The disk brushless motor is connected with the planetary gear reduction mechanism. The planetary gear reduction mechanism is connected with a connection flange. The connection flange passes through centers of the steering control, the planetary gear reduction mechanism and the disk brushless motor. One end of the connection flange is connected with the steering control, and the other end of the connection flange is connected with a steering shaftof a steering column. The steering column is connected with a mechanical steering device. The mechanical steering device enables a steering wheel to rotate. The steering wheel is provided with a rotation angle sensor. The rotation angle sensor is connected with an electronic control unit. The electronic control unit is connected with a motor driver. The motor driver is connected with the disk brushless motor.

Description

technical field

[0001] The invention relates to the field of automatic control of agricultural machinery, in particular to an electric automatic steering system for agricultural machinery. Background technique

[0002] With the proposal and continuous development of precision agriculture and smart agriculture, automatic navigation or unmanned driving has become one of the basic functions of agricultural machinery, which will greatly improve the accuracy of farmland operations while reducing the labor intensity of operators. Automatic steering is one of the necessary functions of automatic navigation agricultural machinery. It can receive steering control commands issued by automatic navigation devices in real time to ensure that the steering wheels of agricultural machinery rotate to the desired angle.

[0003] The Chinese patent No. 201010110694.6 adopts the method of connecting hydraulic circuits in parallel on the basis of the original tractor hydraulic steering to realiz...
