Feed quantity measuring method and feed quantity monitoring device for combine harvester

Abstract

Disclosed are a feed quantity measuring method and a feed quantity monitoring device for a combine harvester. The feed quantity measuring method is characterized in that threshing efficiency is measured by means of roller speed measurement and roller torque measurement, and real-time measurement of feed quantity of the combine harvester is achieved by technically fusing advancing speed data of the harvester and crop yield data. The feed quantity is detected by indirectly measuring crop yield, rotational speed of a threshing roller, torque of the threshing roller and advancing speed of the harvester. A crop yield measuring device is capable of obtaining the time lagged crop feed weight value and comparing the value with average ratio of grain to straw and the harvester advancing speed datameasured by a combine harvester advancing speed measuring device to obtain actual feed quantity, a roller speed measuring device and a roller torque measuring device are capable of measuring rotational speed and torque of the roller to obtain real-time power of the threshing roller, and finally a vehicular computer fuses the measurement values to determine the feed quantity of the combine harvester in real time.

Description

technical field [0001] The invention relates to the technical field of detection and monitoring of precision agricultural machinery equipment, in particular to a method for measuring the feeding amount of a combine harvester and a feeding amount monitoring device. Background technique [0002] Feed rate is an important design parameter and performance parameter of grain harvesting machinery. During the harvest season, on the one hand, the working quality of the combine harvester will be reduced due to the over-feeding amount, and even the working parts will be frequently blocked; Decreased performance and low work efficiency. In recent years, a lot of work has been done on the quantitative test of the feed rate of combine harvesters at home and abroad. For example, some agricultural machinery experts in the United States have tested the delivery torque sensor, engine speed sensor, A variety of feed test sensors such as header auger torque sensor, grain auger torque sensor,...
