- Jul 17, 2018 -

As early as the mid-1960s, a small number of plant protection machinery manufacturers in China began to develop and produce China's first backpack sprayers by themselves with reference to the Japanese prototype.By the end of the 1970s, there were three or four more manufacturers in China.Annual sales have been in the tens of thousands.After entering the 1990s, with the support of the national policy, the first peak year of demand for carrying machines appeared from 1991 to 1992.The production factory has developed rapidly from five or six to more than ten.The post-development enterprises are mainly township collective enterprises.In bearing machine good development situation, research institutes actively cooperating with production enterprises, reduce the operator work intensity, the structure and material of bearing machine fan is improved, the development and production of a new generation with machine - before bending replaced the curved fan fan, to partly replace iron quality engineering plastic material, decrease the size of the structure, reduce the weight, improve the corrosion resistance performance.In addition, some large - scale bearing machine manufacturers, while steadily improving product quality and output, continue to introduce and develop new bearing machine products.
