Embodiment Construction
[0047] The components involved in the present invention can be purchased from the market or realized by using the prior art unless otherwise specified.
[0048] An automatic driving control device includes a mechanical part of an electric steering wheel and an automatic navigation control system.
[0049] The mechanical part of the electric steering wheel mainly includes a steering wheel handle 1, a stepping motor 5 (model is 86BYGH004-ZK30, 86 two-phase double-shaft hollow stepping motor), a motor box 4, a cylindrical roller bearing 6, a spline sleeve 8. The steering wheel handle 1 has a diameter of 40 centimeters, and there is a grooved coil 2 designed to increase the friction force. A shaft 3 with a diameter of 30 mm is rigidly connected directly below the center of the steering wheel. The lower end of the shaft is provided with spline teeth. A spline sleeve 8 is connected at the place, and the whole electric steering wheel is installed on the tractor through a spline; the m...

The invention relates to an electric steering wheel for an agricultural machinery and an automatic driving method. The electric steering wheel for the agricultural machinery comprises an electric steering wheel mechanical device and an automatic driving control device. According to the electric steering wheel for the agricultural machinery, an accurate position of a vehicle can be obtained according to a reference station coordinate and a carrier phase observed value; a measuring receiving machine II transmits position information of the vehicle to a vehicle-mounted display controller; the vehicle-mounted display controller controls a steering wheel to rotate to adjust the steering of the vehicle by using a steering controller according to Delta (delta). According to the electric steeringwheel for the agricultural machinery, by using a stepping motor of a hollow rotor shaft to drive the steering wheel to rotate, structure of the electric steering wheel is simpler, the assembling and disassembling of the electric steering wheel are more convenient, the environmental adaptability of the electric steering wheel is high, and the stability and accuracy of the steering wheel during working can be more effectively guaranteed; and by combining the electric steering wheel for the agricultural machinery with an existing RTK-GPS positioning technology, the positioning accuracy is improved, the positioning accuracy can reach centimetre-level, and the automatic driving accuracy is improved.
Description
technical field [0001] The invention relates to an electric steering wheel and an automatic driving method for agricultural machinery, in particular to an automatic driving device based on RTK-GPS Beidou technology. Background technique [0002] Agriculture is the foundation of a country. my country is a large agricultural country, but it is not a strong agricultural country. The most important reason is that the level of mechanization is not enough. The basic unit of agricultural production in my country is small and medium farmers. In recent years, land contracting has become popular. Small and medium farmers Less and less, the scale of agricultural production is increasing, and manual labor is no longer suitable for modern agricultural production. Therefore, the level of agricultural mechanization in our country needs to be urgently improved. [0003] Precision agriculture is a new trend in the development of agriculture in the world today. It is a system that implements a...
