How to break the situation that China's high-end products in the agricultural machinery sector are subject to people?

Compared with the intelligent level of foreign combine harvesters, the domestic harvester intelligent technology started late, and the level of intelligence is mainly based on the monitoring and display of the speed of working parts. The research on grain loss, grain flow monitoring and auxiliary navigation is still In the experimental stage, it has not been commercialized.

The mainstream model of the domestic grain combine harvester market is 5-7 kg/s, the walking chassis is dominated by two drives, the paddy field and the soft field are poorly passable; the operation efficiency is low, the function is single, and the operation parameters are lack of real-time monitoring. And adaptive control devices. The domestic rice combine harvester is easy to slip, sink, and walk when working in a rice producing area with a mud foot depth of more than 40 cm. It lacks operational performance and parameter real-time monitoring devices, and is insufficient for foreign products.

In order to break through the relevant technical blockade, we have developed an intelligent grain combine harvester and a deep mud foot rice combine harvester with independent intellectual property rights and in line with China's national conditions. Lovol Heavy Industries Co., Ltd. led the joint Jiangsu University and Beijing Agricultural Intelligent Equipment Technology Research Center. 9 domestic institutions and scientific research institutions have undertaken the national key research and development project “Intelligent rice and wheat combined harvesting technology and equipment research and development”, mainly engaged in rice and wheat combined harvester monitoring and intelligent control strategy research, intelligent wheeled rice and wheat joint The research work of harvester development, crawler-type full feeding into the deep mud foot field rice combine harvester, and the online monitoring technology that breaks the grain impurity rate, breakage rate and crop feed amount; the cab multi-function electronic control technology and In-vehicle electronic information system integration technology; key technologies such as multi-parameter monitoring and intelligent control system of rice and wheat combined harvester, and finally developed intelligent rice-wheat combine harvester with independent intellectual property rights and deep-grain rice combination harvester. Thereby significantly improving the level of intelligentization of agricultural machinery in China, it is of great significance for accelerating the development of intelligent agricultural machinery and equipment technology, improving the supply capacity of agricultural machinery and equipment, narrowing the gap with foreign mainstream products, supporting the development of modern agriculture and ensuring food and industrial security.

This kind of intelligent combine harvester can avoid the abnormal operation or failure of the combine harvester by online monitoring of various operating state parameters (such as grain loss rate, feed amount, forward speed, drum speed, water content, etc.). In the early stage, due to the lack of experience of the operator, the fault condition was aggravated or even damaged the machine, ensuring the performance of the combine harvester during operation. It is expected that the trouble-free working time of the combine harvester will be increased by 20%, which greatly facilitates the operation of the operator and makes the whole machine The work performance and work efficiency are greatly improved; the on-line monitoring technology of grain content and breakage rate can also be used to further improve the quality of the harvested kernels, which is conducive to the storage of subsequent kernels; the grain flow online monitoring technology can be used to automatically measure the kernels. The development of the production system, combined with the monitoring of grain harvest loss, generates the distribution map of the yield of the field, providing a basis for “fine farming”. Through the development of multi-parameter monitoring and intelligent systems for rice and wheat combine harvesters, it is also possible to provide intelligent system integration services for other agricultural machinery or other forms of vehicles similar to combine harvesters, and its application prospects are very broad.

The implementation of the project will greatly improve the intelligent technical level of China's grain combine harvester, improve the reliability and international competitiveness of China's grain combine harvester products, break the situation of products in the agricultural equipment field, replace the import, and break the intelligent agricultural machinery. The monopoly of the brand and timely entry into the international market. At the same time, it can also cultivate innovative talents for the development and application of agricultural machinery equipment intelligent technology, which is of great practical significance and strategic significance for comprehensively improving the scientific and technological innovation capability and international competitiveness of the agricultural machinery industry and improving the effective supply capacity of agricultural products.
