Under the action of the cross frame 19, multiple groups of screening tubes 20 and the screening net 4 can be driven to rotate synchronously until the screening net 4 with an appropriate aperture is rotated to the position just below the discharge hole 13, so that the chemical materials can be screened conveniently using the screening nets 4 with different apertures.

[0030] Please refer to the attached figure in the instruction manual Figure 1 A stirring assembly is installed on the top wall of the screening box 14, and the stirring assembly includes a first drive motor 15.

[0033] The bolt 22 is screwed to separate it from the screw hole 23, and the collecting frame 21 is moved horizontally to facilitate dumping of the chemical materials in its inner cavity. The mounting frame 7 is moved horizontally to the other side to drive the multiple groups of screening tubes 20 and the screening net 4 to move synchronously.

[0036] Working principle: When using the chemical material screening device for chemical component proportioning, first place the first flat plate 11 stably on the workbench, open the control valve on the feed pipe 16 to allow the chemical material to enter the inner cavity of the screening box 14 through the feed pipe 16, so that the chemical material is automatically guided to the inner cavity of the screening pipe 20 below through the discharge hole 13 under the action of the wedge-shaped structure of the bottom wall of the inner cavity of the screening box 14, and can be screened under the action of the screening net 4, so that the chemical material that meets the particle size requirements can be automatically accumulated in the inner cavity of the collection frame 21.

[0037] When screening is carried out, the cylinder 9 is started to extend and retract periodically, thereby driving the connecting plate 8 to move horizontally. Under the action of the connecting plate 8, the second flat plate 12, the mounting frame 3 and the screening box 14 can be driven to move horizontally synchronously, thereby driving the screening pipe 20 and the first rotating shaft 1 to move synchronously, and the chemical materials can be discharged smoothly during the shaking process to avoid mutual accumulation and blockage.

[0038] When the second flat plate 12 moves, it can drive multiple groups of mounting vertical plates 10 and moving wheels 6 to move synchronously, so that the mounting vertical plates 10 can move synchronously on the outer wall of the limiting frame 5, thereby limiting the moving path of the second flat plate 12. When screening, the first driving motor 15 is started to drive the first rotating shaft 1 to rotate, thereby driving multiple groups of stirring frames 2 to rotate synchronously, thereby stirring the chemical materials in the inner cavity of the screening box 14, facilitating the discharge of the chemical materials.

[0039] When different types of chemical materials need to be screened, the second drive motor 24 is started to drive the second rotating shaft 18 and the cross frame 19 to rotate synchronously at an appropriate angle according to the particle size of the material to be screened. Under the action of the cross frame 19, multiple groups of screening tubes 20 and the screening net 4 can be driven to rotate synchronously until the screening net 4 with an appropriate aperture is rotated to the position just below the discharge hole 13, so that the chemical materials can be screened conveniently using the screening nets 4 with different apertures.

[0040] After the screening is completed, the bolt 22 is screwed to separate it from the screw hole 23, and the collecting frame 21 is moved horizontally to facilitate the dumping of the chemical materials in its inner cavity. The mounting frame 7 is moved horizontally to the other side to drive the multiple groups of screening tubes 20 and the screening net 4 to move synchronously, and then an air pump, air gun and other equipment in the prior art are used to blow out air from bottom to top, and the air flow is used to clean the sieve holes inside the screening net 4.
