When the vibration motor 5 starts to work, raw materials with larger particles continuously pass through the screens 7 under the action of the vibration motor 5, and a pushing component 3 is arranged on one side of the screening box 1;

[0030] In order to improve the utilization rate of raw materials, a pushing component 3 is provided, which includes a first support frame 32, a plurality of second support frames 33 are fixed to one side of the first support frame 32, a second limiting groove 39 is provided inside the first support frame 32, a first limiting groove 38 is provided inside the second support frame 33, a rotating shaft 34 is rotatably connected to the second limiting groove 39 through a bearing, a reduction motor 31 drives the rotating shaft 34 and a plurality of first conical teeth 35 to rotate, and the first conical teeth 35 are meshed and connected with the second conical teeth 310, and the second conical teeth 310 are meshed and connected with the first conical teeth 310. 310 drives the reciprocating screw 36 to rotate, a plurality of first conical teeth 35 are fixedly sleeved on the outer side of the rotating shaft 34, a reduction motor 31 is fixed on the top of the first support frame 32, one end of the top of the rotating shaft 34 is fixed to the output shaft end of the reduction motor 31, the inner wall of the first limiting groove 38 is rotatably connected to the reciprocating screw 36 through a bearing, the outer side of the reciprocating screw 36 is threadedly connected to a slider 37, and one end of the reciprocating screw 36 is fixed with a second conical tooth 310. When the reciprocating screw 36 rotates, it drives the threaded slider 37 to move back and forth along the inner side of the first limiting groove 38.

[0031] The sieve 7 of Fig. 3 is a block diagram of a sieve 7, wherein the sieve 7 is slidably mounted on the support frame 311, and the sieve 7 is moved along the support frame 312 to move in a reciprocating manner along the support frame 312. The sieve 7 of Fig. 3 is a block diagram of a sieve 7, wherein the sieve 7 is slidably mounted on the support frame 311, and the sieve 7 is moved in a reciprocating manner along the support frame 312 to move in a reciprocating manner along the support frame 312 to move in a reciprocating manner

[0032] Working principle: When the raw materials of medicines need to be screened, multiple screens 7 with different mesh diameters are installed from top to bottom inside the screening box 1, with the screen with a large mesh diameter located at the top of the screening box 1 and the screen with a small mesh diameter located at the bottom of the screening box 1. Then the raw materials are added to the feeding rack 2, and the feeding rack 2 passes through the discharge hole 8 and enters the top of the screen 7 at the top of the inner side of the screening box 1. At this time, the switches are pressed respectively to start the vibration motor 5 and the reduction motor 31 to work;

[0033] When the vibration motor 5 starts to work, the raw materials with larger particles continuously pass through the screen 7 under the action of the vibration motor 5.

When the reciprocating screw rod 36 rotates, it drives the threaded slider 37 to reciprocate along the inner side of the first limiting groove 38. At the same time, the slider 37 drives the moving frame 312 to reciprocate along the sliding column 311 on the top of the screen 7, pushing the raw materials with a size smaller than the sieve holes of this layer of screen 7 into the next layer for screening, and at the same time, the raw materials larger than the top of this layer of screen 7 are pushed to both sides, so that the raw materials are accumulated on one side of the discharge hole 8, and under the continuous accumulation and push of the raw materials, the raw materials are pushed into the storage box 4. At this time, raw materials of different sizes after screening can be obtained in multiple storage boxes 4.

[0034] In summary, the combination of the vibration motor 5 and the pushing component 3 is used to achieve rapid screening and pushing of raw materials. By setting up multiple sieves 7 with different sieve hole diameters and arranging them from top to bottom according to the sieve hole diameters, it is ensured that the raw materials can be accurately screened according to the particle size, thereby obtaining raw materials of different sizes. The reciprocating slider 37 and the movable frame 312 push the raw materials larger than the sieve holes of the current sieve 7 to both sides, avoiding the accumulation of large particles of raw materials on the sieve 7, thereby improving the utilization rate of the raw materials.
