The level of spare parts technology determines the level of the entire agricultural machinery industry

The transmission tape for agricultural machinery is one of the key spare parts for agricultural machinery equipment. It is the core connection component of the power transmission of electromechanical equipment. Its quality and longevity directly affect the trouble-free working time of agricultural machinery. Currently used include continuously variable transmission belts, joint belts, general transmission belts, and light transmission belts.

Agricultural machinery is an indispensable equipment for improving the efficiency of crop cultivation and harvesting, realizing the effective use of resources, and promoting the sustainable development of agriculture. With the implementation of the land transfer policy, China has initially formed large-scale agricultural production, and the technical level of domestic agricultural machinery brands has been continuously improved. The agricultural machinery with high rate, high performance, high reliability and intelligence has been produced on a large scale.

The level of spare parts technology determines the level of the entire agricultural machinery industry

The gradual expansion of the agricultural machinery market capacity has gradually increased the demand for agricultural machinery tape. In 2015, the total demand for agricultural machinery tape was about 600 million yuan. Domestic agricultural machinery tape top three Wuxi Zhonghui (main brand "Zhongliang"), Maanshan Ruisheng (main brand "Liannong") and another company, accounting for 60% of the market share; foreign agricultural machinery tape brand only Japan Han Dong The advantage in the Chinese market is significant.

The improvement of the quality of the whole machine and the adjustment of the industrial structure will promote the continuous improvement of the technical level of the agricultural machinery transmission belt. High-performance agricultural machinery transmission tapes and agricultural machinery transmission tapes with large transmission power, high transmission efficiency and long service life have been fully localized and can replace imports. Its application range has also been gradually expanded, and it has expanded to the power transmission mode of cash crop harvesting machines such as cotton pickers and potato machines.

In terms of material selection, the main materials for the transmission belts of foreign agricultural machinery mainly use neoprene and aramid rope structures. Domestic transmission belts for agricultural machinery are mainly based on neoprene and natural rubber polyester cord structures. However, a major breakthrough has been made in the key technologies of the aramid fiber base formula. The key performance (fatigue life) of the neoprene and aramid rope structure products has reached the advanced level in foreign countries.

In terms of equipment manufacturing level: After years of development, domestic agricultural machinery transmission belt manufacturing equipment has basically reached the same level as European and American countries, but the manufacturing process level needs further optimization.

In 2010, the molding production equipment began to be gradually automated, and the multi-function forming and cutting machine replaced the traditional five steps of cutting, cutting, topping, topping and thinning, and synchronized with Europe and America.

The quality capability can be verified. In the past two years, through the Jiangsu Province Belt Drive System Engineering Technology Research Center, all kinds of agricultural machinery transmission belts at home and abroad have been tested under the same conditions and found that the fatigue life of some domestic transmission belts is close to or exceeds the foreign products. Level. In recent years, China's agricultural machinery tape belt fatigue test verification capability has been rapidly improved, greatly shortening the development time of new products, and providing correct performance indicators for the whole machine manufacturer to achieve simultaneous research and development.

In terms of standardization construction level: Since the “Twelfth Five-Year Plan”, China's agricultural machinery tape implementation standards have been gradually improved, and the infinitely variable V-belt, narrow V-belt, ordinary joint belt, light V-belt, and ordinary belt have national standards. However, with the development of agricultural machinery, the demand for agricultural machinery transmission belts has increased, and the standard revision and revision work has failed to keep up with the development of agricultural machinery, resulting in: agricultural machinery combined with V belt (HB, HC joint belt), agricultural aircraft with light combined V belt ( SB\SC type joint belt), V belt for agricultural machinery (HA, HB, HC, HD single belt), special V belt for agricultural machinery (HDJ), such products are widely used in the agricultural machinery industry, but no special country / Industry Standard.

At present, there are hundreds of enterprises producing agricultural machinery tapes in China, but there are not many large-scale enterprises. There are fewer enterprises that have real research and development and have independent intellectual property rights. Most of them are imitations, product quality stability and reliability are poor, which also hinders the development of agricultural machinery. .

With the entry of world agricultural machinery giants such as Klass, John Deere, and Case New Holland into China, the competition of agricultural machinery enterprises has gradually evolved into competition in the industrial chain, especially the competition of core spare parts enterprises.

As a core spare parts transmission tape enterprise, we must constantly innovate, internal quality, external refining services, internal and external repairs, in order to become a pivotal part of the industrial chain, enhance the external competitiveness of Chinese agricultural machinery enterprises. At present, Wuxi Zhonghui has production equipment synchronized with European and American countries. There are 3 sets of automatic splicing units, 8 sets of automatic forming units, 30 sets of drum vulcanization, 1 automatic rolling production line, and will continue to introduce advanced equipment to further enhance The level of manufacturing automation, the quality has reached the international advanced level.

The quality and quality of agricultural machinery parts and components affect the reliability of the whole machine quality, and the spare parts enterprises are not strong, so the Chinese agricultural machinery industry is difficult to be strong. According to the "Made in China 2025" strategy implemented by the state, China's agricultural machinery and equipment manufacturing industry will focus on cultivating core competitiveness in the next 10 years, achieving strategic adjustments to adapt to the new economic normal through industrial structure optimization, and developing new agricultural machinery and equipment. This requires that the technical level and product quality of agricultural machinery tape must be rapidly upgraded to meet the development needs of the agricultural machinery industry.

The agricultural machinery tape industry needs to strengthen research on new materials, new technologies and new processes, achieve breakthroughs through systematic design and modular manufacturing, improve the technical level of agricultural machinery transmission tapes, verify the transmission system, and develop synchronously, and further improve the whole machine. The reliability and trouble-free working time are of great significance to the rapid development of China's agricultural mechanization. China's agricultural machinery tape industry needs to become an internationally influential industry.
