[0027] With the above structure, through the arrangement of the limiting seat 608, the limiting seat 608 can play a role in limiting and fixing the rotating rod 606, so that the crushing blades 607 will not easily fall off when performing the crushing work.
[0028] In a preferred embodiment, the motor 602 is electrically connected to the controller 7, the diameter of the small rotating wheel 603 is smaller than that of the large rotating wheel 605, the crushing blades 607 are evenly distributed on the outer wall of the rotating rod 606 in a cross-shaped manner, and the limiting seat 608 is fixedly installed on the top of the crushing barrel 2;
[0029] With the above structure, by the controller 7 emitting a signal, the motor 602 can start to work, so that the motor 602 can drive the small rotating wheel 603 to rotate, and through the belt 604, the large rotating wheel 605 drives the rotating rod 606 to rotate on the inner wall of the crushing barrel 2, so that the crushing blades 607 can play a role in crushing the preparation powder placed on the inner wall of the crushing barrel 2.
[0030] In a preferred embodiment, the filtering assembly 8 includes a filtering box body 801, a filter net 802 is installed on the top of the filtering box body 801, a coarse filtering plate 803 and a fine filtering plate 807 are respectively slidably connected to the inner wall of the filtering box body 801, a clamping block 806 is fixedly installed on the outer wall of the filtering box body 801, handles 805 are fixedly assembled on the outer walls of the coarse filtering plate 803 and the fine filtering plate 807, and a buckle 804 is arranged on the outer wall of the filtering box body 801;

[0033] Working principle: When using this device, first, the preparation powder is put into the inner wall of the crushing barrel 2 through the feed hopper 5, and the controller 7 emits a signal to make the motor 602 start to work. Then the motor 602 drives the small rotating wheel 603 to rotate, and through the belt 604, the large rotating wheel 605 drives the rotating rod 606 to rotate in the inner wall of the crushing barrel 2. Thus, the crushing blades 607 can crush the preparation powder placed on the inner wall of the crushing barrel 2. The larger particles of the crushed preparation powder will flow down from the arc-shaped groove 12 to the inner wall of the collection pipe 10 for recycling, while the finer preparation powder can pass through the filter net 802 and be multi-filtered by the coarse filter plate 803 and the fine filter plate 807. Furthermore, impurities in the preparation powder can be effectively removed. After using it for a period of time, the buckle 804 can be taken out from the inner wall of the clamping block 806, and the coarse filter plate 803 and the fine filter plate 807 can be taken out from the inner wall of the filter box body 801 through the handle 805 and cleaned. Thus, it can effectively prevent the coarse filter plate 803 and the fine filter plate 807 from being blocked after using for a period of time, enabling this device to complete the crushing and filtering work of the preparation powder.
