Adaptive anti-clogging control system and control method for cutting longitudinal flow combine harvester

Abstract

The invention relates to a self-adaptive anti-blocking control system for a tangential and longitudinal flow combine harvester. The self-adaptive anti-blocking control system is mainly applied to harvesting machines for crops so as to solve the problem that materials are blocked, overloaded and the like in the process of crop harvesting of the tangential and longitudinal flow combine harvester at present. A self-adaptive anti-blocking control method comprises the following steps of: detecting the working load of a tangential and longitudinal flow threshing device by using a host controller; in the threshing and separating process, detecting the rotating speed and the torque of a tangential flow roller and a longitudinal shaft flow roller by using a detection sensor; calculating a change deviation value; comparing the change deviation value with a prestored standard value and judging; and controlling working parameters of a threshing separation device of the tangential and longitudinal flow combine harvester according to the change of the rotating speed and the torque. By the self-adaptive anti-blocking control system and the self-adaptive anti-blocking control method, the harvesting efficiency of the tangential and longitudinal flow combine harvester is improved; failure rate is reduced; harvesting cost is saved; and labor intensity of workers is greatly reduced. The self-adaptive anti-blocking control system and the self-adaptive anti-blocking control method are also suitable for other kinds of combine harvesters.

Description

technical field [0001] The invention belongs to the field of manufacture and control in agricultural machinery harvesting, and in particular relates to an adaptive anti-blocking threshing separation control system and method when agricultural harvesting machinery threshing and separating crops in the field. Background technique [0002] The working environment of agricultural machinery is very harsh when harvesting in the field. The quality of the crops to be threshed and separated is varied. During the threshing process, there are large differences in material moisture content and instability in the feeding amount, which often leads to overload. The torque and speed of the threshing drum suddenly change. Large, causing blockage of the threshing drum and serious damage to the transmission device, and also increasing the harvesting cost of the crops. At present, the anti-clogging method in the harvesting process mainly relies on the experience of the machine operator to reali...
