[0002] Biopesticides refer to preparations that use living organisms, such as fungi, bacteria, insect viruses, genetically modified organisms, natural enemies, etc., or their metabolites to kill or inhibit agricultural pests. They are also called natural pesticides. They are non-chemically synthesized chemicals or living organisms that come from nature and have the effects of fungicides and insecticides. Biopesticides include microorganisms such as nematodes, bacteria and viruses, plant derivatives and insect pheromones. Biopesticides play a role in the integrated pest management system used in organic agriculture.

During use, when the traditional first poisonous gas filter and the second poisonous gas filter are blocked and need to be cleaned, not only is it necessary to stop the filtration of the exhaust gas and clean the first poisonous gas filter and the second poisonous gas filter, but also manual cleaning is required by personnel, which is more troublesome, thereby greatly reducing the efficiency of the exhaust gas filtration and further affecting the efficiency of the biological pesticide production. For this reason, it is necessary to design a new technical solution to solve this problem. Utility Model Content

During operation, when the gas filter disc 31 filters the exhaust gas, the driving motor 2 is started to drive the connecting ring 52 and the cleaning plate 23 to rotate at a uniform speed, thereby cooperating with the cleaning brush 24 to automatically clean the impurities adsorbed on the gas filter disc 31, and then there is no need to stop the machine for manual cleaning, thereby further improving the efficiency of exhaust gas filtration and the efficiency of biopesticide production, and the limiting block 51 is placed in the limiting groove 5 and then fixed by the fixing bolt 3, so that the fixing bolt 3 is convenient for removing the connecting ring 52 and the cleaning ring from the drive shaft 21, and then the bolt 53 is convenient for removing the gas filter disc 31, which is convenient for removing and replacing the damaged gas filter disc 31.
