Self-adaptation control device and method of grain harvesting machine header

Abstract

The invention discloses a self-adaptation control device of a grain harvesting machine header. A header body is connected with a vehicle body axle of a harvesting machine; one end of a reel bracket isconnected with the header body, and a reel is installed at the other end of the reel bracket; spring tooth shafts are installed on the reel, and spring teeth are installed on the spring tooth shafts;a cutter pendulum ring box is installed below the reel; shaft heads at the two ends of an auger are fixed to the two side walls of the header body through bearings; a cutter is installed on a pendulum rod of the cutter pendulum ring box; by utilizing an information collection device, the work state of the harvesting machine is acquired, and adjustment is conducted. The invention discloses the self-adaptation control device and method of the grain harvesting machine header. For matching of the operation state of the harvesting machine header and the operation speed and feeding quantity of theharvesting machine header, the problems are solved that in order to adapt to different operation conditions, an operator needs to adjust the operation state of the harvesting machine header frequently, and otherwise the harvesting machine cannot work stably; the work efficiency is greatly improved, and the failure rate of the harvesting machine is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and more specifically relates to an adaptive control device and method for a header of a grain harvester. Background technique [0002] Header is an important working unit of grain harvesting machinery. Factors such as header height, reel speed, reel height and front and rear positions directly affect the harvester's feeding amount, harvest quality and efficiency. During the operation of grain harvesters, there are great differences in terrain and soil conditions in different regions, and meteorological conditions also cause differences in ground flatness and crop harvesting status; even in the same plot, due to differences in planting conditions, crop heights and densities vary. uniform. The operator must constantly adjust the operation status of the harvester header according to the crop status and harvesting environment, otherwise there will be jams, missing harvests, overloadi...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides an adaptive control device and method for the header of a grain harvester, which matches the operating state of the header of the harvester with the operating speed and feeding amount, and solves the need for operators to adapt to different operating conditions. Frequently adjust the operation status of the harvester header, otherwise the harvester will not be able to work stably; greatly improve the work efficiency and reduce the failure rate of the harvester
