[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The second motor drives the shaft rod and the extrusion components and swing components on the two sets of side plates to rotate along the two sets of arc-shaped openings, so that the bag rake roller and the extrusion wheel are close to the upper position of the filter plate, and the infusion bag is placed between the filter plate and the bag rake roller. The first motor drives the bag rake roller to rotate and rake the infusion bag inward. The blade set on the inner side of the bag rake roller will cut the infusion bag, and the residual liquid inside falls onto the guide plate along the opening of the filter plate, enters the drain pipe and is discharged outward, reducing the liquid entering the lower side of the crusher and improving the protection of the internal structure of the equipment. The second motor can control the rotation of the bag rake roller and change the distance between it and the filter plate. When facing some relatively clean medical waste, the sleeve and the filter plate fixed on the upper end of the sleeve can be directly driven by the hydraulic cylinder to swing up and down, which promotes the waste to come down, and the crushing roller and the screw conveyor will crush and transport it out.

[0015] 2. When the bag-raking roller rakes the waste to the inside, the motor drives the extrusion wheel to rotate through the bag-raking roller in conjunction with the connection between the two sets of synchronous wheels and the synchronous belt. At this time, the rotating extrusion wheel squeezes and conveys the cut infusion bag again, and discharges the unclean liquid again to improve the cleanliness of the waste. The two sets of positioning springs are pressed against the limit roller. When facing some harder materials, the limit roller has a small upward displacement to avoid jamming.

[0016] 3. Driven by the rotation of the extrusion wheel, the two groups of corrugated convex discs rotate, and the wave-shaped convex blocks push the limit plate and the movable rod to slide along the positioning frame, compressing spring 2. Combined with the elastic characteristics of spring 2, when the corrugated convex disc rotates, the movable rod will move back and forth laterally, driving several groups of spring 1 and swing blocks to swing at the same time, breaking up the infusion bag and better contacting it with the hot air generated by the drying mechanism.

[0017] 4. As the extrusion wheel continuously pushes the material backward, the cut waste slowly moves to the bottom of the square shell, and the airflow blown out by the fan is heated by the heating rod, so as to dry the slowly moving waste, further improve the cleanliness of the liquid on the infusion bag, and avoid the contact between the lower parts of the crusher and the residual liquid as much as possible. In addition, after the work is completed, the rake bag roller and the square shell are controlled to rotate by motor 2, and the baffle on one side of the square shell approaches the filter plate and fits on the upper end of the rear side of the filter plate. The rake bag roller is lifted, which is convenient for the staff to clean the rake bag roller, the extrusion wheel and the filter plate surface, and the fitted baffle minimizes the direct entry of clean wastewater into the crusher. After the square shell rotates down, the round block will be placed on the inclined bar. As the square shell rotates and descends, the inclined bar will pull the round block and the connecting rod forward, so that the openings of several groups of grille bars face the front side, and then the use of the heating rod and the fan accelerates the drying of the cleaned filter plate.

[0034] The motor 2 515 drives the shaft 514 and the squeezing components 512 and the swinging components 513 on the two sets of side plates 58 to rotate along the two sets of arc-shaped openings 516, so that the bag-raking roller 59 and the squeezing wheel 5121 are close to the upper end of the filter plate 52, and the infusion bag is placed between the filter plate 52 and the bag-raking roller 59. The motor 1 511 drives the bag-raking roller 59 to rotate and rake the infusion bag inwardly. The blade 510 provided on the inner side of the bag-raking roller 59 will cut the infusion bag, and the residual liquid inside will flow out along the opening of the filter plate 52. It falls onto the guide plate 51, enters the drain pipe 53 and is discharged outward, reducing the amount of liquid entering the lower side of the crusher 1 and improving the protection of the internal structure of the equipment. The motor 2 515 can control the rake bag roller 59 to rotate and change the distance between it and the filter plate 52. When facing some relatively clean medical waste, the hydraulic cylinder 56 can directly drive the sleeve 57 and the filter plate 52 fixed on the upper end of the sleeve 57 to swing up and down, thereby promoting the waste to come down, and the crushing roller 2 and the screw conveyor 3 will crush it and transport it out.

[0035] The extrusion assembly 512 includes an extrusion wheel 5121 movably arranged between two groups of side plates 58, a synchronous wheel 5122 is fixedly arranged on the rotating shaft on the same side as the rake bag roller 59 at one end of the extrusion wheel 5121, and a synchronous belt 5123 is sleeved on the two groups of synchronous wheels 5122. A movable frame 5124 is arranged in the middle position of the two groups of side plates 58, a positioning spring piece 5125 is fixedly arranged on the inner side of the movable frame 5124, and a limiting roller 5126 is movably arranged on the inner side of the positioning spring piece 5125, and corrugated convex discs 5127 are fixedly arranged on the outer sides of the rotating shafts on both sides of the extrusion wheel 5121.

[0036] The extrusion wheel 5121 is closer to the filter plate 52 than the bag rake roller 59. The two groups of extrusion components 512 and the synchronous belt 5123 are located in a group of cavities 54. The movable frame 5124 is tilted. The positioning spring 5125 is pressed against the upper side of the limiting roller 5126. The limiting roller 5126 is sleeved on the outer side of the rotating shaft of the extrusion wheel 5121. The limiting roller 5126 is slidably set in the movable frame 5124. The two groups of corrugated convex discs 5127 are located on the inner sides of the two groups of side plates 58. The edges of the corrugated convex discs 5127 are provided with a plurality of corrugated protrusions.

[0037] When the bag raking roller 59 raks the waste to the inside, the motor 1 511 drives the squeezing wheel 5121 to rotate through the bag raking roller 59 in coordination with the connection between the two sets of synchronous wheels 5122 and the synchronous belt 5123. At this time, the rotating squeezing wheel 5121 squeezes and conveys the cut infusion bag again, and discharges the unclean liquid again, thereby improving the cleanliness of the waste. The two sets of positioning springs 5125 are pressed against the limiting roller 5126. When facing some harder materials, the limiting roller 5126 has a small upward displacement to avoid getting stuck.

[0038] The swing assembly 513 includes two groups of positioning frames 5131 fixedly arranged at opposite ends of the two groups of side plates 58, and movable rods 5132 are movably arranged on the front and rear sides of the two groups of positioning frames 5131, and a plurality of groups of springs 1 5133 are fixedly arranged at the lower end of the movable rod 5132, and a swing block 5134 is fixedly arranged at the lower end of the spring 1 5133, and limiting plates 5135 are fixedly arranged at both ends of the movable rod 5132, and springs 2 5136 are sleeved between the outer sides of the rotating shafts on both sides of the movable rod 5132, close to the limiting plates 5135 and the positioning frames 5131.

[0039] The two groups of movable rods 5132 are fixedly connected, and a plurality of groups of springs 5133 are evenly arranged on the lower side of the movable rods 5132 . The group of the two groups of limiting plates 5135 close to the corrugated convex disk 5127 is attached to the corrugated convex disk 5127 .

[0040] Driven by the rotation of the extrusion wheel 5121, the two groups of corrugated convex discs 5127 rotate, and the wavy convex blocks push the limiting plate 5135 and the movable rod 5132 to slide along the positioning frame 5131, compressing the spring 2 5136. Combined with the elastic characteristics of the spring 2 5136, when the corrugated convex disc 5127 rotates, the movable rod 5132 will move back and forth laterally, driving several groups of spring 1 5133 and swing blocks 5134 to swing at the same time, breaking up the infusion bag and better contacting it with the hot air generated by the drying mechanism 6.

[0041] The drying mechanism 6 includes a square shell 61 fixedly arranged at the rear ends of the two groups of side plates 58, a plurality of groups of heating rods 62 are fixedly installed on the upper end of the square shell 61, three groups of fans 63 are fixedly installed on the inner side of the square shell 61, a plurality of groups of connecting shafts 64 are fixedly arranged near the two sides of the lower end of the square shell 61, two groups of connecting shafts 64 opposite to each other on both sides of the square shell 61 are movably connected with grille bars 65 inside, two groups of connecting rods 66 are movably connected with the lower sides of the plurality of groups of grille bars 65, round blocks 67 are fixedly arranged near the front sides at the opposite ends of the two groups of connecting rods 66, and inclined bars 68 are fixedly arranged on the inner walls of both sides of the crusher 1.

[0042] An inclined baffle is fixedly provided at the lower end of the square shell 61 near the rear side. The heating rod 62 and the fan 63 are electrically connected to the external control terminal. The round block 67 is close to the upper side of the inclined bar 68, and the inclined bar 68 is inclined.

[0043] As the extrusion wheel 5121 continuously pushes the material backward, the cut waste slowly moves to the bottom of the square shell 61, and the airflow blown out by the fan 63 is heated by the heating rod 62, thereby drying the slowly moving waste, further improving the cleanliness of the liquid on the infusion bag, and avoiding the contact between the lower part of the crusher 1 and the residual liquid to the greatest extent. In addition, after the work is completed, the motor 2 515 controls the bag-raking roller 59 and the square shell 61 to rotate, and the baffle on one side of the square shell 61 approaches the filter plate 52 and fits the upper end of the rear side of the filter plate 52, and the bag-raking roller 59 and the square shell 61 are rotated. The roller 59 is lifted up to facilitate the staff to clean the rake bag roller 59, the extrusion wheel 5121 and the surface of the filter plate 52, and the fitted baffle minimizes the direct entry of clean waste water into the crusher 1. After the square shell 61 rotates down, the round block 67 will be placed on the inclined bar 68. As the square shell 61 rotates and descends, the set inclined bar 68 will pull the round block 67 and the connecting rod 66 forward, so that the openings of several groups of grille bars 65 face the front side, and then the use of the heating rod 62 and the fan 63 can accelerate the drying of the cleaned filter plate 52.

[0044] Working principle: When in use, the motor 2 515 drives the shaft 514 and the extrusion components 512 and the swing components 513 on the two sets of side plates 58 to rotate along the two sets of arc-shaped openings 516, so that the bag-raking roller 59 and the extrusion wheel 5121 are close to the upper end of the filter plate 52, and the infusion bag is placed between the filter plate 52 and the bag-raking roller 59. The motor 1 511 drives the bag-raking roller 59 to rotate and rake the infusion bag inward. The blade 510 set on the inner side of the bag-raking roller 59 will cut the infusion bag, and the residual liquid inside will flow out along with the filter plate 52. The outlet falls onto the guide plate 51, enters the drain pipe 53 and is discharged outward, reducing the amount of liquid entering the lower side of the crusher 1 and improving the protection of the internal structure of the equipment. The motor 2 515 can control the rake bag roller 59 to rotate and change the distance between it and the filter plate 52. When facing some relatively clean medical waste, the hydraulic cylinder 56 can directly drive the sleeve 57 and the filter plate 52 fixed on the upper end of the sleeve 57 to swing up and down, so as to promote the waste to come down, and the crushing roller 2 and the screw conveyor 3 will crush and transport it out. In addition, the rake bag roller 5 When the waste is raked inward, the motor 1 511 drives the extrusion wheel 5121 to rotate through the bag raking roller 59 in coordination with the connection between the two sets of synchronous wheels 5122 and the synchronous belt 5123. At this time, the rotating extrusion wheel 5121 squeezes and conveys the cut infusion bag again, discharges the unclean liquid again, and improves the cleanliness of the waste. The two sets of positioning springs 5125 are pressed against the limiting roller 5126. When facing some harder materials, the limiting roller 5126 has a small upward displacement to avoid being stuck. ; Secondly, driven by the rotation of the extrusion wheel 5121, the two groups of corrugated convex discs 5127 rotate, and the wave-shaped convex blocks push the limit plate 5135 and the movable rod 5132 to slide along the positioning frame 5131, compressing the second spring 5136. With the elastic characteristics of the second spring 5136, when the corrugated convex disc 5127 rotates, the movable rod 5132 moves back and forth laterally, driving several groups of springs 1 5133 and swing blocks 5134 to swing at the same time, breaking up the infusion bag and better contacting it with the hot air generated by the drying mechanism 6;As the extrusion wheel 5121 continuously pushes the material backward, the cut waste slowly moves to the bottom of the square shell 61, and the airflow blown out by the fan 63 is heated by the heating rod 62, thereby drying the slowly moving waste, further improving the cleanliness of the liquid on the infusion bag, and avoiding the contact between the lower part of the crusher 1 and the residual liquid to the greatest extent. In addition, after the work is completed, the motor 2 515 controls the bag rake roller 59 and the square shell 61 to rotate, and the baffle plate on one side of the square shell 61 approaches the filter plate 52 and fits the upper end of the rear side of the filter plate 52, and the bag rake roller 59 is lifted, which is convenient for the staff to clean the rake bag roller 59, the extrusion wheel 5121 and the surface of the filter plate 52, and the fitted baffle minimizes the direct entry of clean wastewater into the crusher 1. After the square shell 61 rotates down, the round block 67 will be placed on the inclined bar 68. As the square shell 61 rotates and descends, the set inclined bar 68 will pull the round block 67 and the connecting rod 66 forward, so that the openings of several groups of grid bars 65 face the front side, and then the use of the heating rod 62 and the fan 63 accelerates the drying of the cleaned filter plate 52. ;
