[0034] Example 1

[0035] like Figures 1-5 As shown, the present invention proposes a pharmaceutical dispensing and sieving device, including a sieving box 1, a feeding hopper 2 for introducing materials on the top of the sieving box 1, a discharge valve 3 fixedly installed at the bottom of the sieving box 1, four support legs arranged in a rectangular pattern fixedly installed at the bottom of the sieving box 1, two material receiving doors 4 on the front of the sieving box 1, and a vibrating screen structure 5 for sieving materials inside the sieving box 1.

[0036] The vibrating screen structure 5 includes a motor 501 for driving and screen plates 502 and 503 for screening materials. Multiple springs 504 are fixedly installed on the top of screen plate 502 and the bottom of screen plate 503. Mounting plates 505 are fixedly installed on the other end of the multiple springs 504. The mounting plates 505 are fixedly connected to the inner wall of the screening box 1. Screen plates 502 and 503 are movably connected to the inner wall of the screening box 1. Two sets of sliding grooves are provided on the inner walls of both sides of the screening box 1. Two sliders are fixedly installed on both sides of screen plates 502 and 503. The sliders are movably connected to the sliding grooves. Gear 507 is fixedly installed on the output shaft of motor 501. Two push rods 506 for extrusion are fixedly installed on the output shaft of motor 501.

[0037] In this embodiment, during screening, the motor 501 is first started, and then the material to be screened is introduced into the screening box 1 through the feed hopper 2. The output shaft of the motor 501 drives the gear 507 and two push rods 506. The push rods 506 intermittently squeeze the screen plate 502 and the screen plate 503. The screen plate 502 and the screen plate 503 then squeeze the spring 504. When the push rod 506 separates from the screen plate, the spring 504 applies a pushing force to the screen plate. The slider on one side slides in the groove. When the slider is in contact with the inner wall of the groove, the screen plate will vibrate, which can achieve the effect of vibrating the material on the top of the screen plate. Frequent vibration can reduce the situation where the material is stuck upright in the screen hole of the screen plate, and reduce the probability of equipment blockage.

[0038] Example 2

[0039] like Figures 1-6As shown, based on Embodiment 1, the screening box 1 is equipped with a cleaning structure 6. The cleaning structure 6 includes a reciprocating lead screw 1 601 and a reciprocating lead screw 2 602. One end of each of the reciprocating lead screw 1 601 and the reciprocating lead screw 2 602 is fixedly equipped with a pulley 603. The same belt is fitted on the two pulleys 603. The other end of the reciprocating lead screw 1 601 is fixedly equipped with a gear 2 604. The gear 1 607 and the gear 2 604 mesh and drive each other. Both the 2nd and 3rd sections of the screen box 1 are equipped with cleaning plates 608. Reciprocating screw 1 601 and reciprocating screw 2 602 are each movably equipped with internal threaded blocks 605. Two limiting rods 606 are movably mounted on the internal threaded blocks 605, and both limiting rods 606 are fixedly connected to the inner wall of the screen box 1. Connecting seats 607 are fixedly mounted on both internal threaded blocks 605. The cleaning plates 608 and connecting seats 607 are movably connected. Limiting grooves are provided on both sides of the inner wall of the connecting seats 607. Limiting grooves are fixed on both sides of the cleaning plates 608. The positioning block, the limiting block, and the limiting groove are movably connected. Multiple springs 609 are fixedly installed inside the connecting seat 607. The other ends of the multiple springs 609 are fixedly connected to the cleaning plate 608. The cleaning plate 608 can move up and down under the action of the springs 609 to automatically adjust to the height of the screen plate. When the motor 501 rotates, gear 507 drives gear 604, which in turn drives reciprocating screw 601. Reciprocating screw 601 then drives reciprocating screw 602 via pulley 603. 602, reciprocating screw one 601 and reciprocating screw two 602 simultaneously drive the internal thread block 605 to move left and right. The internal thread block 605 then drives the cleaning plate 608. The two cleaning plates 608 are respectively attached to the top of screen plate one 502 and the bottom of screen plate two 503, which can push over some of the material stuck in the screen holes and make it participate in the screening again, which can optimize the vibration screening effect of the equipment. The cleaning plate 608 can move up and down under the action of spring two 609 to automatically adapt to the height of the screen plate.

[0040] The above specific embodiments are merely several optional embodiments of this utility model.
