High-power tractor market has a touch of Chinese red

A few days ago, the “Eleventh Five-Year” National Science and Technology Support Program “Development of Multi-Functional Agricultural Equipment and Facilities” major project review and acceptance conference organized and organized by China Academy of Agricultural Mechanization Science was held in Harbin. The main red appearance, supplemented by the black "Eastern Red" 200 horsepower tractor, became the focus of acceptance.

According to Zhao Yanshui, the general manager of China Yituo Group Co., Ltd., which is responsible for the development of the tractor, the tractor has broken through 10 key technologies such as digital modeling, closed-center load sensing, electronically controlled hydraulic suspension, and soil biomimetic drag reduction, and its grade performance indicators. Has reached the advanced level of similar foreign products, can gradually achieve alternative imports.

In view of the fact that the current domestic market is mainly dependent on imports of tractors of more than 125 horsepower, in 2007, the Ministry of Science and Technology proposed to develop a research target of 147k (200 hp) for calibration power in the “development of multifunctional agricultural equipment and facilities” and set “the rated traction ≥ 39kN, load shift gearbox, gear number ≥ 16, closed-end load sensing hydraulic system, electronically controlled suspension, maximum lifting force ≥45kN” and a series of technical and economic indicators.

Through the joint efforts of all project participants, the Dongfanghong 200 horsepower tractor has 23 patents, including 3 invention patents. "In the performance will never lose to John Deere, New Holland and other imported high-power tractors." Zhao said the water. "It adopts a self-developed energy-saving and environment-friendly diesel engine that meets Euro III emission standards and is a model for energy conservation and environmental protection in agricultural machinery."

Combined with another sub-problem, "High-powered Tractor Duplex Working Equipment Research and Development" independently developed a wide range of joint land preparation, no-tillage precision sowing fertilization and cultivator, wide high-efficient warranty and other supporting complex work tools, can achieve high-power tractor operations The whole of China. At present, the whole set of equipment has been widely used in the main grain-producing areas such as the Northeast, which can reduce production costs by 20%, reduce oil consumption by 20%, conserve 3-4 kg/mu, save 30% to 40%, and increase water storage and waterlogging production. %-15% to increase fertilizer utilization by 10%-15%.

It is understood that "multi-functional agricultural equipment and facilities development" is by far the most funded project for China's policy support for agricultural equipment industry research and development, and it is also a pilot project for the organization of major national projects led by enterprises transformed by the institute. It is implemented by the Ministry of Science and Technology. The enterprise is the main body and an active attempt is made to integrate the innovation system of production, education and research.

The project includes a total of 17 sub-topics. More than 1,200 people from 105 units across the country participated in, breaking through 126 key common technologies, developing 118 new agricultural equipment products, 114 new processes, new materials, and new devices, and 94 standards for development. There are 526 scientific papers, 12 published science and technology works, 336 patent applications, 47 computer software development projects, and 7 national and provincial awards.

Experts at the meeting stated that the output of a series of achievements has greatly improved the overall level of China's agricultural equipment.
