Basic introduction of backpack electric spray dust collector

As early as the mid-1960s, a few plant protection machinery manufacturers in China began to develop and produce the first-generation backpack machine in China-WFB-18AC backpack machine with reference to the Japanese prototype. By the end of 1970s, there were three or four backpacker manufacturers in China, each of which developed their own backpacker products. The national annual production and sales volume has been maintained at tens of thousands of vehicles. After entering the 1990s, with the support of national policies, 199 1 to 1992 saw the first peak demand year for piggyback machines. The number of manufacturers has rapidly developed from five or six to more than 10. The post-development enterprises are mainly township collective enterprises, and the products are mainly WBF WBF-18AC backpack machines. Under the good development situation of backpack machine, scientific research institutes actively cooperate with production enterprises to improve the fan structure and materials of WFB ~ 18AC backpack machine from the perspective of reducing the working intensity of operators, and develop and produce a new generation of 18 backpack machine —— replacing the back-bent fan with the forward-bent fan and replacing some iron materials with engineering plastics, thus reducing the structural size, reducing the weight of the whole machine and improving the corrosion resistance. In addition, some large backpack manufacturers are constantly introducing and developing new backpack products while steadily improving product quality and output. At present, there are about 20 domestic manufacturers of backpack machines with more than one variety 10, with an annual output of several hundred thousand sets.

Backpackers are widely used in large-scale pest control of agricultural and forestry crops, as well as chemical weeding, foliar fertilization, spraying plant growth regulators, urban health and epidemic prevention, eliminating storage pests and livestock ectoparasites, spraying particles and so on. Not limited by geographical conditions, it is very suitable in mountainous areas, hilly areas and sporadic plots.
