Abstract

The invention discloses an automatic steering device for an agricultural machine steering wheel. The automatic steering device comprises a base support and a drive system support. A pressure spring and a connecting rod mechanism are connected between the drive system support and the base support. The drive system support is provided with a friction mechanism capable of driving the agricultural machine steering wheel to rotate. A friction pressure adjusting mechanism is arranged on the base support. One end of the pressure spring is connected with the drive system support, and the other end of the pressure spring is connected with the friction pressure adjusting mechanism. A steering wheel strut clamping mechanism is arranged at the end portion of the base support. By the adoption of the automatic steering device, manual control and electric control are freely switched at any time, the device is installed and detached conveniently and quickly, meanwhile, the high adaptability is achieved, the requirements for the installation accuracy and the concentricity of the steering wheel are low, the automatic steering device can adapt to steering wheels of various styles, and the requirements for different agricultural machines are well met.

Description

technical field [0001] The invention relates to an agricultural machinery automatic navigation technology, in particular to an agricultural machinery steering wheel automatic steering device. Background technique [0002] Automatic navigation of agricultural machinery is a core key technology in the precision agricultural technology system, which is widely used in agricultural production processes such as farming, sowing, fertilizing, spraying, and harvesting. Agricultural machinery position measurement method, agricultural machinery model and navigation path tracking control method are the research focus of automatic navigation technology of agricultural machinery, which have attracted extensive attention of domestic and foreign researchers. The role of the navigation system is to make agricultural machinery work according to the optimized operation path, reduce the area of ​​repeated operation areas and missed operation areas, improve the quality and efficiency of agricult...
