The other end of the belt 17 is sleeved on the outside of the driven wheel 18. The rotation of the driving wheel 27 can drive the belt 17 to rotate so that the driven wheel 18 can rotate. The rear end of the driven wheel 18 is fixedly connected with a transmission rod 2 19, and the transmission rod 2 19 can be rotated by the driven wheel 18. The rear end of the transmission rod 2 19 is fixedly connected to the rear end inner wall of the processing box 1, so that the rotation of the transmission rod 2 19 is more stable. The outside of the transmission rod 2 19 is fixedly connected with a plurality of crushing rods 20, and the rotation of the transmission rod 2 19 will drive the crushing rod 20 to rotate. The left end of the processing box 1 is fixedly connected with a loading box 21, and the left end of the loading box 21 is fixedly connected with a feeding port 22. Powder is added through the feeding port 22. The top of the loading box 21 is fixedly connected with an electric Machine 23, the driving end of motor 23 is fixedly connected with a rotating rod 24, and motor 23 will drive the rotating rod 24 to rotate when started, and the bottom of the rotating rod 24 is rotatably connected to the bottom inner wall of the loading box 21, and the outside of the rotating rod 24 is fixedly connected with a rotating piece 25. The rotation of the rotating rod 24 will drive the rotating piece 25 to rotate, so as to load the powder. The top of the right end of the loading box 21 is fixedly connected with a connecting pipe 26, and the bottom of the connecting pipe 26 is fixedly connected to the top of the processing box 1. This is to connect so that the powder can enter the interior of the processing box 1. The powder is poured into the feed port 22 and enters the interior of the loading box 21 through the feed port 22. At this time, motor 23 is started, and the rotating rod 24 will be rotated when the motor 23 is started, and the rotating piece 25 will be rotated by the rotation of the rotating rod 24, so that the powder will rise through the rotation of the rotating piece 25 and enter the connecting pipe 26, and enter the interior of the processing box 1 through the connecting pipe 26.

[0029] Working principle: First, when using, pour the powder into the feed port 22, and enter the interior of the loading box 21 through the feed port 22. At this time, start the motor 23, and the motor 23 will drive the rotating rod 24 to rotate, and the rotation of the rotating rod 24 will drive the rotating sheet 25 to rotate, so that the powder will rise through the rotation of the rotating sheet 25 and enter the connecting pipe 26, and enter the interior of the processing box 1 through the connecting pipe 26. At this time, start the motor 2, and the motor 2 will drive the transmission rod 3 to rotate, and the rotation of the transmission rod 3 can drive the driving wheel 27 to rotate, and when the driving wheel 27 rotates, the belt 17 will also be rotated, and the rotation of the belt 17 will drive the driven wheel 18 to rotate, and finally, the rotation of the driven wheel 18 drives the transmission rod 2 19 to rotate the crushing rod 20, and the rotation of the crushing rod 20 will hit the powder entering the processing box 1, so that the agglomerated powder is separated, which can improve the efficiency of subsequent screening. The powder after being struck falls to the top of the sieve plate 10, and the transmission rod 3 rotates with the striking disk 4, and the rotation of the striking disk 4 can strike the sieve plate 10. At this time, the sieve plate 10 pushes the fitting block 9, and the fitting block 9 pushes the sliding column 6 upward, so that the spring 7 is squeezed and deformed. The sieve plate 10 can be reset more efficiently through the spring 7, which can further improve the screening efficiency. When needed, the control rod 13 can be pulled. The limit block 14 will move with it, and the movement of the limit block 14 will squeeze the spring 15, and the movement of the control rod 13 will also push out the inner wall of the slot 12, so that the limit plate 11 can be taken out. At this time, the sieve plate 10 can not only collect the unscreened powder remaining on the surface, but also replace the sieve plate 10 as needed, so as to adapt to different powder sizes and requirements. Finally, the screened powder enters the interior of the powder return box 16, and the powder return box 16 is taken out and the powder is returned by pulling the handle.
