Abstract

The invention discloses a load feedback speed regulation device for a combined harvester and a control method in the field of agricultural machinery. The load feedback automatic control device comprises a controller and a sensing system, and is connected with a speed regulation executing mechanism with functions of automatic speed regulation and manual speed regulation; a motor driver is respectively connected with the controller and a motor; the controller is respectively connected with a liquid crystal display, a sound and light alarming system and the sensing system, and is formed by a single chip microcomputer and peripheral circuits thereof; the sensing system is formed by various sensors and a conditioning circuit thereof; and working state signals of the combined harvester are collected by the sensing system, and the working state signals enter the controller to carry out treatment such as a multi-signal fusion fuzzy control algorithm, a forecast control algorithm and the like,and a corresponding control strategy is selected to drive the executing mechanism to work. Therefore, the invention realizes the automatic control of work load of the combined harvester, displays a working state of a unit in real time, carries out sound and light alarm in time when the combined harvester meets faults, has simple and compact structure as well as flexible and overall functions, andis convenient to expand.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic load feedback control device for a combine harvester. Background technique [0002] The harvesting efficiency of a combine harvester is related to its operating load. The operating load varies randomly with factors such as feeding amount, driving speed, drum rotation speed, and grain delivery auger rotation speed. The fluctuation of the operating load directly affects the stability and stability of the working state of the combine harvester. harvesting efficiency. If the driving speed is too fast, the threshing drum will be overloaded due to the excessive feeding amount, the speed of the threshing drum will decrease and the loss will increase, and even the threshing drum and the grain conveying auger will be blocked, resulting in failure; Low and low operating efficiency, so it is required to regulate the load when the combine harvester is operating. At presen...
