[0083] Example 1

[0084] The medical waste is input into the interior of the shell 8 from the first discharge port 804 at the top of the shell 8, and the motor 603 is turned on to drive the rotating rod 604 to rotate. The rotation of the rotating rod 604 will drive the fixed column 605 at the end of the rotating rod 604 to slide along the bar-shaped through hole 609 on the moving rod. When the fixed column 605 slides in the bar-shaped through hole 609 on the moving rod, it will drive the moving rod, the vertical rod 608 and the sliding rod 606 to move along the guide rod 602. Since the rotating rod 604 rotates in a circle around the output shaft of the motor 603, it will drive the moving rod to reciprocate, and the reciprocating movement of the moving rod will drive the sliding rod 606 to reciprocate, and the reciprocating movement of the sliding rod 606 will drive the first cutting knife 607 to reciprocate, and the first cutting knife 607 cooperates with the second cutting knife 6012 to preliminarily cut the medical waste;

[0085] The medical waste that has been preliminarily cut falls into the pulverizing mechanism 7 from the second discharge port 1201, and the driving motor 402 drives the first pulverizing roller 705 to rotate. Since the gears 707 at the ends of the first pulverizing roller 705 and the second pulverizing roller 702 are meshed, the rotation of the first pulverizing roller 705 will drive the second pulverizing roller 702 to rotate synchronously, thereby achieving the purpose of pulverizing the medical waste that has been preliminarily cut. After the pulverization is completed, the residual liquid in the medical waste will fall into the waste liquid collection frame 11 through the filter hole 1001 at the bottom of the waste collection frame 10, and the pulverized medical waste will be accumulated in the waste collection frame 10.

[0086] Example 2

[0087] In order to facilitate the replacement of the crushing mechanism 7, a sealing member 9 and a pressing member 3 are also provided.

After the crushing mechanism 7 is completed, the sealing plate 90 in the sealing member 9 is inserted into the fixing groove 802 of the shell 8. 2 is placed in the fixing groove 801, so that the vertical plate 904 is against the outer wall of the shell body 8, and the supporting plate 509 is set on the bottom inner wall of the fixing groove 801. After the sealing plate 902 is installed, the lifting plate 304 is pulled down to drive the handle 306, the threaded rod 3012 and the pressing block 3011 to move downward until the pressing block 3011 is located at the sealing plate 902. The handle 306 is rotated to drive the threaded rod 3012 to rotate, and the threaded rod 3012 rotates to drive the pressing block 3011 to approach the sealing plate 902 until the sealing plate 902 is pressed in the fixing groove 801, thereby achieving the purpose of fixing the crushing mechanism 7 and ensuring the safety and stability of the crushing mechanism 7 during the working process.

[0088] Example 3

[0089] In order to prevent the residual liquid in the medical waste from splashing out during the cutting and crushing process of the medical waste, a loading piece 5 is also provided on the top of the shell 8. The handle 506 is pulled to drive the pulling plate 501 to move outward, and the pulling plate 501 moves outward to drive the supporting plate 509 and the second side plate 5010 to move outward until the supporting plate 509 and the second side plate 5010 are pulled out of the placement groove 507. When the pulling plate 501 moves outward, the pulling rod 5013 is pulled, and when the pulling rod 5013 is pulled, the second moving rod 505 is driven to move. When the second moving rod 505 moves, the third spring 5012 is compressed to place the medical waste on the supporting plate 509. Under the action of the third spring 5012, the supporting plate 509 can be driven to reset, and the medical waste is transported to the placement groove 507 at the same time. And under the action of the through hole 508, the medical waste is transported to the cutting mechanism 6 between the vertical plates 6011.
