[0002] The original pesticide cannot be used directly. It must be processed and prepared into various types of preparations before it can be used. The form of the preparation is called the dosage form. Commercial pesticides are sold to users in the form of a certain dosage form. The most commonly used dosage forms in my country are emulsifiable concentrates, suspensions, wettable powders, powders, granules, aqueous solutions, poison baits, mother liquids, mother powders and more than ten other dosage forms. Among them, wettable pesticide powders are a basic dosage form in pesticide preparations with a long history, relatively mature technology and easy use. It is a powder preparation composed of original pesticides, carriers (fillers), surfactants (wetting agents, dispersants, etc.), adjuvants (stabilizers, color warning agents, etc.) and crushed to a certain fineness.

[0003] Referring to the existing Chinese patent with announcement number CN218401309U, it discloses an exhaust conveying equipment for the production of wettable powders of pesticides, including a first box body and a second box body, the second box body is connected to the first box body through a connecting pipe, a feed hopper is installed on the top of the first box body, an extrusion mechanism is provided in the first box body, a conveying mechanism is provided in the second box body, an opening is provided at one end of the first box body close to the second box body, the first box body is fixedly connected to a mounting plate at the opening position, a first filter screen for filtering air contained in the powder is connected to one side of the mounting plate close to the opening through a connecting rod, a second filter screen is arranged on the mounting plate, and a knocking mechanism is provided between the first filter screen and the second filter screen.

[0004] The above-mentioned exhaust conveying equipment for the production of wettable powders of pesticides performs an extrusion and exhaust treatment on the powder before packaging through the extrusion mechanism arranged in the first box body, and the gas in the powder is discharged through the first filter screen, thereby increasing the bulk density of the powder and improving the powder packaging efficiency. However, the above-mentioned exhaust conveying equipment for the production of wettable powders of pesticides still has some disadvantages, such as: First, when the powder is extruded and exhausted, the extrusion mechanism needs to be moved from left to right and then reset before the next extrusion and exhaust treatment of the powder can be performed, and the powder cannot be continuously extruded and exhausted, thereby reducing the efficiency of powder transportation; Second, after the powder is filtered by the filter screen, it is inconvenient to fully knock and shake off the powder adhering to the filter screen because the filter screen is arranged vertically. In addition, the manual knocking method is used, which increases the workload and the knocking and shaking effect is poor. For this reason, an exhaust conveying equipment for wettable powders of pesticides is designed. Utility Model Content
