Significant technological breakthrough in grain loss testing and verification system

2024-01-22

Recently, the National Agricultural Machinery Equipment Innovation Center has made an important technological breakthrough in the field testing of the grain loss testing and verification system for grain harvesting machinery in Jiamusi. Thisthe first time that the system has achieved precise testing of soybean harvesting machinery, conducting indicator tests for the reliability, adaptability, and economy of soybean harvesting machinery, and evaluating the quality of operations, Mechanized and automated testing can greatly meet the accuracy requirements of mechanical loss rate testing, and make up for the shortcomings in this testing field in China.

During this year's "Three Summers" period, under the unified guidance of the main station, the technical team of the Innovation Center conducted experimental verification and operational evaluation of the grain loss testing and verification system for grain harvesting machinery in Xiangyang, Hubei, Luoyang, Henan, and Baoding, Hebei. The grain loss testing and verification system has achieved mechanization and automation, changing the manual testing method for harvesting quality of harvesters in China to mechanized automation, and achieving on-board and parallel testing. It can achieve testing of different types of harvesters, real-time data transmission, processing, and feedback. The technology team of the Innovation Center has expanded the testing capabilities of soybean and corn grain damage on the wheat testing platform, and recently conducted field testing and verification in Fujin City. After more than 20 days and 10 rounds of testing, it has been shown that the testing capabilities of the grain loss platform for soybeans and corn have been successfully expanded. The technical team has developed a set of different testing modes and parameter configurations for wheat, soybeans, and corn, meeting the requirements of efficient and multi index grain loss testing.

Next, the Innovation Center will also expand the platform's rice testing capabilities. The implementation of mechanized grain loss testing capabilities for soybeans and corn is conducive to providing better services for the industry and promoting the promotion and application of mechanized grain loss testing methods.

Grain harvesting is an important part of the entire agricultural production process. Improving the quality of testing is of great significance for reducing harvest losses and ensuring high yields. At the site of the operation evaluation activity in Baoding, Hebei, Academician Luo Xiwen of the Chinese Academy of Engineering carefully listened to the introduction of the mechanized grain loss testing platform and observed the experimental verification and operation of the grain harvesting machinery grain loss testing verification system. Academician Luo highly recognizes the work of the Innovation Center and stated on site that the precise measurement of grain loss testing and verification system for harvesting machinery has changed the manual testing method used for harvesting quality in China, greatly improving sampling efficiency. This not only provides a basis for the next step of machine harvesting loss reduction, but also relates to the particle storage of main grain crops and national food security. In August this year, Liu Hengxin, the director and deputy secretary of the Party Committee of the Agricultural Mechanization Station of the Ministry of Agriculture and Rural Affairs, pointed out during a research and guidance session at the Innovation Center that the grain loss machinery testing and verification system will enrich the various parameters of harvesting machinery in terms of grain loss, and can greatly meet the accuracy requirements of machine harvesting loss rate testing. He affirmed the work of the Innovation Center in building a comprehensive testing service platform for agricultural machinery and equipment, The main station will continue to pay attention to and guide the experimental and verification work of the Innovation Center in the comprehensive testing of agricultural machinery and equipment. It is also hoped that the Innovation Center can play the role of a national platform, increase the efforts to introduce and cultivate innovative technologies, and contribute to the rapid development of agricultural machinery and equipment.

The quality testing and verification of grain, soybean, and corn harvesters have made up for the shortcomings in China's testing field. Not only can it provide guidance for the optimization of harvesters, but it can also provide data support for the promotion and application of intelligent agricultural machinery equipment. It can also explore optimization technology models for the full mechanization of grain production, saving costs and increasing efficiency, thereby helping to promote the high-quality development of agricultural machinery and ensuring national food security.
