[0016] The powder pesticide pulverizing device of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementations.

[0017] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0018] See also Figure 1-2 The present embodiment is a powder pesticide pulverizing device, which utilizes stirring blades and grid plates to initially crush large pieces, and then utilizes vertical rollers to fully crush small pieces, and filters and separates the powder through a screen to keep the particle size of the powder uniform. The device mainly includes a pulverizing box 1 and a pulverizing mechanism and a separating mechanism arranged in the pulverizing box.

[0019] A feed hopper 2 is provided on the upper part of the crushing box 1. The feed hopper 2 is provided above the side of the crushing box 1. A butterfly valve 3 is provided in the middle of the feed hopper 2 for controlling the feeding speed. The lower part of the feed hopper 2 is connected to the side of the crushing box 1.

[0020] The crushing mechanism includes a stirring blade and a vertical roller 9, and the stirring blade and the vertical roller 9 are powered by a driving unit. The driving unit includes a stirring shaft 4, a pulley group 5 and a motor 6. The pulley group 5 is respectively installed at the ends of the stirring shaft 4 and the motor 6, and the stirring shaft 4 is driven to rotate by the motor 6. The stirring blade includes a roller 7, an eccentric blade 8 and a rotating shaft. The rotating shaft is laterally fixed on the stirring shaft 4, and the rollers 7 are selectively connected to the rotating shaft in side by side. A top ball is installed on the surface of the roller 4 to promote the turning of the material. The cross-section of the eccentric blade 8 is trapezoidal, and its own weight is used to drive the material to move on the grid plate under the blade, thereby speeding up the material discharge speed at the partition and avoiding blockage.

[0021] The separation mechanism includes a screen 11, a drop port 12 and a collection bin 13. Rolling grooves 9 are evenly opened on the outside of the vertical roller 9 to increase friction. A guide cylinder 10 with a gradually decreasing diameter is provided on the outside of the vertical roller 9. The outside of the guide cylinder 10 is fixed on the crushing box 1. The screen 11 is arranged on the outside below the vertical roller 9. The drop port 12 is arranged at the closing position of the lower end of the screen 11. The collection bin 13 is arranged below the screen 11, and a valve 14 is provided at the bottom of the collection bin 13.

[0022] During use, the material is conveyed into the feed hopper, and the butterfly valve is opened to control the discharge of the material. The material enters the crushing box, where it is first stirred by the rotating roller. At the same time, the eccentric blade uses its own weight to drive the material onto the grid plate, prompting the material to actively contact the grid plate. The partition separates the material and increases the discharge speed. The material enters the guide cylinder and is fully ground and crushed by the vertical roller. Finally, after screening through the screen, the qualified powder is collected in the collection bin, and the unqualified products are collected at the discharge port for the next step of processing.
