From 18 to 19, many people in the United States, Britain and other countries have developed and designed combine harvesters, and some have obtained patents and made prototypes, but they are basically of no practical value.
It was not until the 1920s that the combine harvester was first used on a large scale in the wheat producing areas of the United States, and then quickly spread to the Soviet Union, Canada, Australia and Western European countries. 2 1 century, developed countries in Europe and America have fully realized agricultural mechanization, and combine harvesters are developing towards large-scale, high-speed, reliability and high adaptability.
In order to improve the utilization rate and adaptability of machines and make them work efficiently, safely and reliably, foreign agricultural machinery enterprises in Europe and America generally adopt computers to carry out computer-aided design (CAD), computer-aided testing (CAT) and computer-aided manufacturing (CAM), and integrate new technologies of mechatronics, automation and intelligence to monitor and control the operating parameters of combine harvesters in real time. For example, the load detection system of threshing drum can reduce or prevent clogging.
The harvesting monitoring system enables the operator to observe the working condition, machine position and walking route of the machine in real time for real-time adjustment. Harvest Doc measures and records crop yield, humidity and productivity in real time, and users store this information, which lays the foundation for establishing accurate agricultural prescription map. Harvesmart's crop feed is based on threshing drum.
Monitor the grain loss rate and engine load of visual Tra, and automatically adjust the walking speed of combine harvester to ensure the balanced and consistent feeding of crops. Because the combine harvester is equipped with the above advanced detection and control technology, the manipulator only needs to observe the information transmitted to the cab display interface by each detection system.
Through related operations, the combine can work smoothly in various field environments and different parameters of various crops, and the intermediate process is completed by each system identification operation. The application of mechanical, electrical and hydraulic integration and intelligent new technology has greatly improved the work efficiency of combine harvester, reduced grain loss and reduced driver's fatigue.
