Hydraulic self-adaptive driving control system of hydraulic variable-diameter threshing cylinder and self-adaptive control method

Abstract

The invention provides a hydraulic self-adaptive driving control system of a hydraulic variable-diameter threshing cylinder and a self-adaptive control method. The hydraulic self-adaptive driving control system comprises a hydraulic driving system, an online monitoring system, a self-adaptive control system, a traveling forward speed executing mechanism and a sound alarm, wherein the hydraulic driving system can achieve adjustment of the diameter of the threshing cylinder and achieve self-locking after diameter adjustment, the on-line monitoring system can monitor the running forward speed of a harvester, the threshing gap of a hydraulic variable-diameter roller threshing device and the oil pressure of a rodless cavity end of a hollow hydraulic cylinder in real time, and the self-adaptive control system compares and judges the monitored real-time oil pressure parameter with the corresponding oil pressure parameter range in a reference model, and adaptively adjusts the driving forward speed and the threshing gap so as to solve the problem of material blockage in the working process of the combine harvester. According to the hydraulic self-adaptive driving control system of the hydraulic variable-diameter threshing cylinder and the self-adaptive control method, the fault-free working time and the harvesting efficiency of the longitudinal axial flow combine harvester with the hydraulic variable-diameter threshing cylinder can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery equipment, in particular to a hydraulic adaptive drive control system and an adaptive control method for a hydraulic variable-diameter threshing drum of a longitudinal axial flow combine harvester. Background technique [0002] The planting area of ​​rice in China is very wide and there are many varieties. Due to the differences in topography, soil environment, and sunshine duration in different regions, these factors have caused great differences in the growth density and biomechanical properties of rice. the difference. In recent years, a large number of super rice has been planted in my country, which has the characteristics of high yield, dense growth, thick stems, and high moisture content. The above reasons lead to a large feeding amount and large fluctuations in the working process of the combine harvester, which is likely to cause blockage of the threshing device. [0003]...
