Self-adaptive regulation and control system and method for ratooning rice stubble cutting height and stubble supporting operation

Abstract

The invention provides a ratooning rice stubble cutting height and stubble supporting operation self-adaptive regulation and control system and method. The ratooning rice stubble cutting height and stubble supporting operation self-adaptive regulation and control system comprises a stubble supporting device, a profiling contact type sensor, a speed radar and a controller. The stubble supporting device is arranged at the tail of the harvester and connected with the hydraulic cylinder support through a stubble supporting device hydraulic cylinder. The profiling contact type sensor is used for detecting the ground clearance of the header and transmitting the ground clearance to the controller; the speed radar is used for acquiring speed information of the harvester and transmitting the speed information to the controller; the hydraulic valve group is arranged on the chassis upper rack and is respectively connected with the header lifting hydraulic cylinder and the stubble supporting device hydraulic cylinder; the input end of the controller is connected with the profiling contact type sensor and the speed radar, and the output end of the controller is connected with the motor and the hydraulic valve set. While ratooning rice in the first season is harvested, stubbles rolled by the crawler belt or the wheel type walking device are righting, the integration of ratooning rice harvesting and righting can be effectively achieved, and the yield loss of the second season is reduced.

Description

technical field [0001] The invention belongs to the technical field of ratooning rice combine harvesters, and in particular relates to an adaptive regulation system and a regulation method of ratooning rice stubble cutting height and stubble support operation parameters. Background technique [0002] Raising rice is a kind of rice with two harvests. It is the most potential rice planting model for increasing grain production, and it is also a powerful means to achieve poverty alleviation. With the continuous acceleration of agricultural mechanization, the operation technology of ratooning rice mechanized harvesting is still relatively weak. The rolling rate in the straight line is generally 40-50%, and it is as high as 80-90% in the turning area, which seriously affects the output in the regeneration season and the regeneration output in the rolling area is less than 10%. The traditional straightening method of ratooning rice stubble cutting is mainly based on manual assist...

AI Technical Summary

Problems solved by technology

The straight rolling rate is generally 40-50%, and the turning area is as high as 80-90%, which seriously affects the output of the regeneration season. The regeneration output of the rolling area is less than 10%.

The traditional righting method of ratooning rice stubble cutting is mostly manual assistance, which has a large workload and low operating efficiency, and is not suitable for large-scale planting, which restricts the large-scale promotion of ratooning rice
