DETAILED DESCRIPTION

When working, the pesticide granule raw materials to be screened are poured onto the filter plate 12 through the opening The switch of the driving motor 15 is turned on, so that the driving motor 15 drives the first rotating rod 16 to rotate, and then the cam 17 located on the first rotating rod 16 pushes the filter plate 12 to move in the direction away from the first rotating rod 16 when it rotates to a certain position. When the cam 17 continues to rotate, the top pressure of the cam 17 is lost, and the filter plate 12 is reset under the elastic reset of the reset spring 14. In this process, the filter plate 12 will be continuously pushed and pulled back and forth, so that the raw materials located on the filter plate 12 can be shaken back and forth, so that during the screening process, the raw materials accumulated on the filter plate 12 can be better and faster to fall to the bottom for screening. By making the filter plate 12 constantly swing, the raw materials accumulated on the filter plate 12 can be better dropped, and the raw material particles blocked in the mesh are shaken off due to their own potential energy under the shaking of the filter plate 12, thereby reducing the possibility of blockage and improving the screening effect of the pesticide particle raw materials.

[0025] like Figures 2 to 4As shown, the side wall of the screening box 1 is fixedly connected to a support frame 2; the side wall of the support frame 2 is fixedly connected to a driving motor 21; the output end of the driving motor 21 is fixedly connected to a second rotating rod 22; the second rotating rod 22 passes through the side wall of the screening box 1, and is rotatably connected to the screening box 1; the second rotating rod 22 is arranged below the filter plate 12; a plurality of groups of elastic rods 23 are fixedly connected to the middle of the second rotating rod 22; the elastic rods 23 are arranged in an array on the second rotating rod 22; a collision ball 24 is fixedly connected to the end of the elastic rod 23; a plurality of groups of spring pieces 25 are fixedly connected to the side wall at the bottom of the filter plate 12; the position of the collision ball 24 corresponds to the spring piece 25, and when working, by turning on the switch of the driving motor 21 When the second rotating rod 22 rotates, the elastic rod 23 on the second rotating rod 22 is driven to rotate, so that the collision ball 24 collides with the spring piece 25 under the filter plate 12. When the collision ball 24 collides with the spring piece 25, the spring piece 25 vibrates, and then transmits the vibration to the filter plate 12 and the baffle 13, so that the raw materials adhering to the surfaces of the filter plate 12 and the baffle 13 are shaken off and separated, so that the raw materials are better screened, and the raw materials blocked in the mesh are better dropped into the inside of the screening box 1, thereby increasing the screening effect of the raw materials and reducing the problem that some raw materials adhere to the surfaces of the filter plate 12 and the baffle 13 and are difficult to screen.

[0026] like Figures 2 to 4 As shown, the side wall of the screening box 1 is rotatably connected to multiple groups of second synchronous wheels 31; the middle of the second rotating rod 22 is fixedly connected to the first synchronous wheel 3; the side wall of the second synchronous wheel 31 is fixedly connected to the third rotating rod 32; the third rotating rod 32 passes through the side wall of the screening box 1 and is rotatably connected to the screening box 1; the middle of the third rotating rod 32 is provided with an elastic rod 23 and a collision ball 24, and the structure is the same as that on the second rotating rod 22; a synchronous belt 33 is installed between the second synchronous wheel 31 and the first synchronous wheel 3. When working, by providing multiple third rotating rods 32 on the screening box 1, it is possible to use a power source drive motor 21 to drive multiple groups of collision balls 24 to rotate through the connection of the synchronous belt 33. By providing collision balls 24 and shrapnel 25 in multiple positions, the filter plate 12 can be subjected to a larger vibration range, and a better vibration effect can be achieved while using less power source cost, thereby improving the screening effect of the raw materials.

[0027] like Figure 5As shown, a cavity 4 is provided inside the second rotating rod 22 and the third rotating rod 32; a pair of protrusions 41 are fixed inside the cavity 4; the protrusions 41 are symmetrically arranged; a plurality of steel balls 42 are placed inside the cavity 4. During operation, by arranging the steel balls 42 inside the second rotating rod 22 and the third rotating rod 32, the steel balls 42 can be driven to roll when the second rotating rod 22 and the third rotating rod 32 rotate, and when the steel balls 42 roll into the air after passing through the protrusions 41 and fall, they impact the wall of the second rotating rod 22, thereby causing the second rotating rod 22 to vibrate slightly, and the raw materials that fall and adhere to the second rotating rod 22 are shaken off, thereby reducing the waste of raw materials and improving the collection effect of raw materials.

[0028] like Figure 3 As shown, the side wall of the filter plate 12 is fixedly connected with an elastic cloth 5; the end of the elastic cloth 5 is fixedly connected to the inner wall of the screening box 1; the elastic cloth 5 is arranged below the supporting telescopic rod 11. When working, by arranging the elastic cloth 5 between the screening box 1 and the filter plate 12, the problem of waste of raw materials caused by dust in the raw material screening process can be reduced, and the raw materials are protected by the elastic cloth 5, which further improves the collection effect of the raw materials.

[0029] like Figure 2 and Figure 4 As shown, a shock-absorbing pad 6 is fixedly connected to the end of the driving motor 21; the shock-absorbing pad 6 is arranged between the driving motor 21 and the support frame 2. When working, by arranging the shock-absorbing pad 6 on the driving motor 21, the vibration generated when the driving motor 21 is working can be reduced, the protection effect of the driving motor 21 is improved, and the service life of the driving motor 21 is increased.

[0030] Working principle: by pouring the pesticide granule raw materials to be screened onto the filter plate 12, by turning on the switch of the driving motor 15, the driving motor 15 drives the first rotating rod 16 to rotate, and then the cam 17 located on the first rotating rod 16 pushes the filter plate 12 to move away from the first rotating rod 16 when it rotates to a certain position, and when the cam 17 continues to rotate, the top pressure of the cam 17 is lost, so that the filter plate 12 is reset under the elastic reset of the reset spring 14, and in this process, the filter plate 12 will be continuously pushed and pulled back and forth, so that the raw materials located on the filter plate 12 can be shaken back and forth, so that in the process of screening the raw materials, the raw materials accumulated on the filter plate 12 can be better and faster to fall to the bottom for screening, and by making the filter plate 12 constantly swing, the raw materials accumulated on the filter plate 12 can be better dropped, so that the raw material particles blocked in the mesh are shaken off due to their own potential energy under the shaking of the filter plate 12, thereby reducing the possibility of blockage and improving the screening effect of the pesticide granule raw materials.

[0031] By turning on the switch of the driving motor 21, the driving motor 21 drives the second rotating rod 22 to rotate. When the second rotating rod 22 rotates, the elastic rod 23 on the second rotating rod 22 is driven to rotate, so that the collision ball 24 collides with the shrapnel 25 under the filter plate 12. When the collision ball 24 collides with the shrapnel 25, the shrapnel 25 vibrates, and then transmits the vibration to the filter plate 12 and the baffle 13, so that the raw materials adhered to the surfaces of the filter plate 12 and the baffle 13 are shaken off and separated, so that the raw materials can be better screened, and the raw materials blocked in the mesh can be better dropped into the inside of the screening box 1, thereby increasing the screening effect of the raw materials and reducing the problem that some raw materials adhere to the surfaces of the filter plate 12 and the baffle 13 and are difficult to screen.

[0032] By providing a plurality of third rotating rods 32 on the screening box 1, a plurality of groups of collision balls 24 can be driven to rotate by a power source driving motor 21 through the connection of a synchronous belt 33. By providing collision balls 24 and shrapnel 25 at multiple positions, the vibration range of the filter plate 12 can be expanded, and a better vibration effect can be achieved while using less power source cost, thereby improving the screening effect of the raw materials.

[0033] By arranging steel balls 42 inside the second rotating rod 22 and the third rotating rod 32, the steel balls 42 can be driven to roll when the second rotating rod 22 and the third rotating rod 32 rotate. When the steel balls 42 roll into the air after passing through the protrusion 41 and fall, they impact the wall of the second rotating rod 22, thereby causing the second rotating rod 22 to vibrate slightly, and the raw materials that have fallen and adhered to the second rotating rod 22 are shaken off, thereby reducing the waste of raw materials and improving the collection effect of raw materials.

[0034] By providing an elastic cloth 5 between the screening box 1 and the filter plate 12, the problem of waste of raw materials caused by dust during the raw material screening process can be reduced. The raw materials are protected by the elastic cloth 5, and the collection effect of the raw materials is further improved.

[0035] By providing the shock-absorbing pad 6 on the driving motor 21 , the vibration generated when the driving motor 21 is working can be reduced, thereby improving the protection effect of the driving motor 21 at work and increasing the service life of the driving motor 21 .
