The sterilization treatment system includes units for steam supply, material feeding and transfer, high-temperature sterilization, and crushing. It uses two independent sterilization carts in conjunction with three transfer platforms to transport medical waste. After sterilization, operators pour the medical waste into the crusher, and after crushing, it is directly collected and transported. However, the process of operators pouring medical waste into the crusher increases their workload and the risk of infection.

[0003] In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hopper device that uses a pusher plate to pour medical waste from the hopper device into a crushing device for crushing, thereby achieving the purpose of reducing the labor intensity and infection risk of operators without manual intervention.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: This invention provides a hopper device, comprising: The hopper has a discharge port on one side along its length. The push plate abuts against the inner wall of the basket on its outer periphery; The material pushing assembly is located between the hopper and the push plate, and is used to control the push plate to slide along the length of the hopper toward or away from the discharge port.

[0006] Furthermore, the pusher assembly includes: A linear guide rail extends along the length of the bucket basket and to the discharge port where it connects to the power source. The connectors are connected to the push plate and the linear guide rail respectively, which drives the push plate to move with the linear guide rail.

[0007] Furthermore, the connector includes: The slider, whose side facing inwards towards the basket, is fixedly connected to the push plate; The pressure plate is fixed to the upper side of the slider and works with the slider to clamp the linear guide rail.

[0008] Furthermore, the slider has a locking part protruding on the side facing the inside of the basket; The outer periphery of the push plate is bent away from the discharge port to form a flange; a notch is provided on the flange; After the snap-fit ​​part slides into the notch, it is fixedly connected to the flange.

[0009] Furthermore, a guide rod is provided below the slider; The guide slide is supported by a guide slide block that gradually narrows from bottom to top; The lower side of the slider is provided with a guide hole with the opening facing downward; The guide slide rod is fastened to the guide slide rod through the guide slide hole; The two end faces at the opening of the guide slide hole are adapted to the sides of the guide slide that extend vertically and vertically, while maintaining a gap.

[0010] Furthermore, the basket includes an external support frame and an internal liner; The snap-fit ​​part passes through the support frame and the inner liner in sequence and connects with the push plate; The guide slide and guide slide are mounted on the support frame.

[0011] Furthermore, a linkage assembly is provided between the support frame and the door panel of the discharge port to allow the door panel to flip up and down; The linkage assembly is supported on the support frame by a hinged bracket and runs through the support frame from top to bottom. Its upper end is hinged to the inside of the door panel, and its lower end is hinged to the support frame and slidably connected. Preferably, the linkage assembly includes a first link, a second link, and a third link, with the first link located below the second link and above the third link.

[0012] Furthermore, the inner side of the door panel is provided with vertically extending guide grooves; The inner side of the guide groove is provided with a hinge shaft extending along the width direction of the bucket basket; The upper end of the second link is hinged to the hinge shaft; The guide groove below the hinge shaft provides space to accommodate the rotating link assembly.

[0013] Furthermore, a control slide is provided on the support frame; The control slide is equipped with a control slide rod that slides along the length of the bucket basket; The lower end of the third link is hinged to the control slide.

[0014] Furthermore, the bottom of the hopper is provided with a rack extending along its own length, which is used to mesh with the gear on the transfer device to drive and transfer the hopper and define the position of the hopper; The basket is equipped with guide wheel sets on its side wall along its width direction, which are used to match the guide rails on the transfer device; Preferably, the inner liner, push plate, and door panel are all provided with a high-temperature resistant non-stick layer; Preferably, the bottom of the inner liner is a downward-curved drainage arc surface, and a row of spaced drainage holes is provided at the lowest point of the bottom of the inner liner along the length of the basket.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. By using a pusher plate to pour medical waste from the hopper into the crushing equipment for crushing, no manual intervention is required, which can reduce the labor intensity and infection risk of operators.

[0016] 2. The high-temperature resistant non-stick layer prevents medical waste from sticking to the inner liner, the drainage hole prevents water accumulation in the inner liner, and the door panel opens and the push plate pushes the medical waste out of the inner liner, thereby reducing the number of times operators come into contact with medical waste and reducing the risk of infection and high-temperature burns to operators during the transportation of medical waste.

[0017] 3. The temperature of medical waste is still very high when it first enters the hopper and during the transfer process. The guide wheel assembly can keep the hopper stable during the movement to the transfer device. The rack and pinion and guide wheel assembly simultaneously limit the position of the hopper to prevent the water droplets on the surface of the medical waste from splashing onto the operator during the transfer process, and to prevent the hopper from falling. This strengthens the connection stability between the hopper and the transfer device, and further reduces the risk of infection and high temperature burns to the operator.

[0025] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. Example 1

[0026] like Figures 1 to 7 As shown, the present invention provides a hopper device, including an upward-opening hopper basket 1, a door panel 2, and a pusher plate 3.

[0027] The hopper 1 includes an outer support frame 11 and an inner liner 12. Multiple drainage holes 4, penetrating the inside and outside of the hopper 1, are spaced apart on the bottom and side walls of the inner liner 12. A discharge port 13 is provided on one side of the hopper 1 along its length. A hinge connects the top of the door panel 2 and the support frame 11 located at the top of the discharge port 13, allowing the door panel 2 to rotate upwards or downwards to cover the discharge port 13. An opening and closing assembly 5 is provided between the hopper 1 and the door panel 2 to control the upward or downward rotation of the door panel 2. A pusher plate 3 is located inside the cavity of the inner liner 12, with its periphery adapted to fit against the inner wall of the inner liner 12. A pushing assembly 6 is provided between the hopper 1 and the pusher plate 3 to control the sliding of the pusher plate 3 along the length of the hopper 1.

[0028] When medical waste is placed in the hopper 1, the door panel 2 is closed, and the push plate 3 abuts against the side wall of the inner liner 12 opposite the door panel 2. The medical waste is located between the door panel 2 and the push plate 3. The drainage hole 4 not only allows the water accumulated in the medical waste to flow to the outside of the hopper, but also accelerates the cooling of the medical waste. The opening and closing assembly 5 controls the door panel 2 to flip upward and open the discharge port 13. The pushing assembly 6 controls the push plate 3 to move closer to the door panel 2, thereby pushing the medical waste away from the discharge port 13 from the hopper 1.

[0029] In addition, since medical waste tends to stick to the inner liner 12 under high temperatures, a high-temperature resistant anti-stick layer 7 is provided on the inner liner 12, push plate 3, and door panel 2 to improve this situation. The high-temperature resistant anti-stick layer 7 is preferably made of polytetrafluoroethylene, which is resistant to high temperatures and has a low coefficient of friction. The high-temperature resistant anti-stick layer 7 prevents medical waste from sticking to the inner liner 12, and the drain hole 4 penetrates through the high-temperature resistant anti-stick layer 7, so the drainage of accumulated water is not affected.

[0030] The combination of drainage hole 4 and high-temperature resistant non-stick layer 7 reduces the number of times operators come into contact with medical waste when moving and dumping it, thereby reducing the risk of infection and high-temperature burns to operators during the transportation of medical waste.

[0031] To further guide the condensate accumulated in the inner liner 12 out of the liner 12, the bottom of the inner liner 12 is a downwardly curved drainage arc surface 14, and a row of spaced drainage holes is provided at the lowest point of the bottom of the inner liner 12 along the length of the basket 1. The bottoms of the door panel 2 and the push plate 3 are adapted to the bottom of the inner liner 12 to prevent medical waste from leaking from the door panel 2 or from being missed when the push plate 3 pushes the medical waste.

[0032] The feeding assembly 6 includes a linear guide rail 61, a connector 62, and a guide member 63.

[0033] In this embodiment, linear guide rails 61 are installed on the support frame 11 and multiple sets are arranged on both sides of the push plate 3 along the width direction of the bucket 1. The linear guide rails 61 are arranged along the length direction of the bucket 1 and one end is connected to the power source. In this embodiment, four linear guide rails 61 are provided, and the four linear guide rails 61 are arranged in pairs on both sides of the push plate 3 along the width direction of the bucket 1. The two linear guide rails 61 in the same group are arranged vertically, and the lower linear guide rail 61 is connected to the power source. Connecting the push plate 3 to the four linear guide rails 61 improves the stability of the push plate 3 during its movement. Figure 1 As shown, the length direction of the basket 1 of the present invention is the left-right direction, and the width direction of the basket 1 of the present invention is the front-back direction; Specifically, the linear guide rail 61 extends along the length of the bucket basket 1 and extends to the discharge port 13 to connect with the power source; The linear guide 61 is a synchronous belt, which moves back and forth along the length of the bucket basket 1 under the drive of the power source; The power source can be a device such as an electric motor that can drive the linear guide rail. An electromagnetic clutch is used to connect the power source and the linear guide rail 61. In this embodiment, the flange 64 of the electromagnetic clutch is connected to the linear guide rail 61 to facilitate quick connection of the power source.

[0034] The connector 62 is connected to the push plate 3 and the linear guide rail 61 respectively, causing the push plate 3 to move with the linear guide rail 61; the linear guide rail 61 moves, causing the connector 62 to move, thereby causing the push plate 3 to slide along the length of the basket 1. In addition, the connector 62 includes a slider 621, which is fixedly connected to the push plate 3 on the side facing the inside of the basket 1; The pressure plate 622 is fixed to the upper side of the slider 621 and cooperates with the slider 622 to clamp the linear guide rail 61; specifically, the pressure plate 622 is used to fix the timing belt on the slider 622. The slider 621 and the pressure plate 622 are square block structures. The pressure plate 622 is fixed to the upper side of the slider 621 by screws. The slider 621, the pressure plate 622 and the linear guide 61 are fixed together, so that the slider 621 and the pressure plate 622 move linearly with the linear guide 61. The bottom surface of the pressure plate 622 is provided with a toothed structure that contacts the linear guide rail 61, increasing the friction between the pressure plate 622 and the linear guide rail 61 and improving the stability of the slider 621 and the pressure plate 622 as they move with the linear guide rail 61. The slider 621 has a locking part 623 protruding on the side facing the inside of the bucket basket 1; under the operation of the motor, the electromagnetic clutch drives the synchronous belt pulley to rotate, and the synchronous belt drives the slider 621, the locking part 623 and the push plate 3 to slide linearly.

[0035] Both the high-temperature resistant non-stick layer 7 and the inner liner 12 are provided with connecting grooves 15 arranged along the length of the basket 1. The snap-fit ​​part 623 passes through the connecting groove 15 into the basket 1 and connects with the push plate 3, and slides on the connecting groove 15. The outer periphery of the push plate 3 is bent away from the discharge port 13 to form a flange 31; the flange 31 is provided with a notch 311; the snap-fit ​​part 623 slides into the notch 311 and is fixedly connected to the flange 31.

[0036] Two fixing parts 32 are provided on the side of the flange facing the inside of the basket 1, which are distributed vertically. The two fixing parts 32 are located at the upper and lower parts of the notch 311, respectively. After the snap-fit ​​part 623 passes through the connecting groove 15, it slides into the notch 311. After being snapped into the notch 311, it is fixedly connected to the two fixing parts 32. The snap-fit ​​part 32 snapping into the notch 311 has a pre-positioning function for the fixed connection between the snap-fit ​​part 32 and the two fixing parts 32.

[0037] In addition, the guide member 63 includes a guide slide rod 631 and a guide slide block 632; A guide rod 631 is provided below the slider 621; The guide slide rod 631 is supported by a guide slide block 632 that gradually narrows from bottom to top; The lower side of the slider 621 is provided with a guide hole 633 with the opening facing downward; The guide slide rod 631 is fastened to the guide slide rod 631 through the guide slide hole 633; The two end faces at the opening of the guide slide hole 633 are adapted to the side of the guide slide 632 that extends vertically and vertically, and maintain a gap. The guide member 63 can guide the regular and stable sliding along the length of the basket.

[0038] The support frame 11 has a crossbeam and two vertical beams connected to both ends of the crossbeam; The guide slide 632 is mounted on the crossbeam, and the guide slide rod 631 is fixed to the top of the guide slide 632. Specifically, the guide slide rod 631 is fixed to the top of the guide slide 632, and the two ends of the guide slide rod 631 are in contact with the two vertical beams at both ends of the crossbeam.

[0039] An opening and closing assembly 5 is provided between the support frame 11 and the door panel 2. Two sets of the opening and closing assembly 5 are located on both sides of the door panel 2 along the width direction of the basket 1. The opening and closing assembly 5 includes a hinged support 51 and a connecting rod assembly that causes the door panel 2 to flip up and down. The connecting rod assembly includes a first connecting rod 52, a second connecting rod 53, and a third connecting rod 54.

[0040] The hinged support 51 is installed on the support frame 11. Specifically, the hinged support 51 is installed on the crossbeam of the support frame 11. The linkage assembly is supported on the support frame 11 by the hinge support 51 and passes through the support frame 11 from top to bottom. Its upper end is hinged to the inner side of the door panel 2, and its lower end is hinged to the support frame 11 and slidably connected.

[0041] The center of the first link 52 is rotatably mounted on the hinge support 51 along the rotation direction of the door panel 2. One end of the second link 53 is rotatably hinged to one end of the first link 52 and the other end is rotatably hinged to the door panel 2. One end of the third link 54 is rotatably hinged to the other end of the first link 52. The other end of the third link 54 is connected to a control element 55 for controlling the rotation angle of the third link 54.

[0042] To improve the smoothness and stability of the opening and closing of the door panel 2, the first connecting rod 52 is a curved rod with an obtuse angle triangle shape, thicker in the middle and thinner at both ends, and the second connecting rod 53 is an arc-shaped rod that bends towards the door panel 2. The inner side of the door panel 2 is provided with a guide groove 21 that extends vertically; The guide groove 21 is provided with a hinge shaft 22 extending along the width direction of the basket; The upper end of the second link 53 is hinged to the hinge shaft 22, and the guide groove 21 below the hinge shaft 22 provides a space for the rotating second link 53.

[0043] The vertical beam of the support frame 11 is provided with a sliding groove for the second connecting rod 53 to pass through into the basket 1, and the auxiliary connecting rod assembly makes the door panel 2 flip up and down.

[0044] The lower end of the linkage assembly is hinged to and slidably connected to the support frame 11 via the control element 55.

[0045] The control component 55 includes a control slide 551, a control slider 552, and a control rod 553.

[0046] A control slide 551 is installed on the crossbeam of the support frame 11. The control slide 551 has a control groove 554 that is slidably connected to the control slider 552 along the length of the bucket 1. The third connecting rod 54 has a connecting hole 555 that allows the control slider 553 to pass through coaxially along the width of the bucket 1. The connecting hole 555 of the third connecting rod 54 is hinged to the control slider 553 located on the control slide 551. One end of the control slider 553 is fixed to the control slider 552 and the other end is located on the outside of the bucket 1.

[0047] The control slide bar 553 is moved from the outside of the basket 1. The control slide bar 553 drives the control slider 552 to move along the length of the basket 1. As the control slider 552 slides in the control groove 554, the control slide bar 553 drives the third link 54 to perform a compound motion. The first link 52 rotates accordingly to drive the second link 53 to perform a compound motion, so as to realize the control of the opening and closing of the door. Example 2

[0048] like Figures 8 to 11 As shown, the present invention provides a hopper transfer device, including a lifting support 400, a weighing platform 500, a docking structure 800, an assembly structure 600, a translation structure 700, and a control structure 900.

[0049] The weighing platform 500 has two ends along its length, one for the hopper to enter and the other for the hopper to exit. The entry end of the weighing platform 500 faces the discharge port of the sterilization equipment, and the exit end faces the inlet of the crushing equipment. The sterilization equipment moves the hopper carrying the sterilized medical waste to the discharge port. Because the discharge port of the sterilization equipment and the inlet of the crushing equipment are at different heights, a lifting bracket 400 is needed to adjust the height of the weighing platform 500 to accommodate the different equipment. This setup allows for automatic transfer of medical waste to the crushing equipment without operator intervention, reducing the number of times operators come into contact with the medical waste during transport and lowering the risk of infection and burns.

[0050] The docking structure 800 is located on the side of the weighing platform 500 facing the sterilization equipment and is used for horizontal docking with the discharge port of the sterilization equipment. The assembly structure 600 is used to move the hopper from the discharge port of the sterilization equipment onto the weighing platform 500. The translation structure 700 is installed on the weighing platform 500 and connects the assembly structure 600 and the docking structure 800. The translation structure 700 is used to move the assembly structure 600 and the docking structure 800 together closer to or further away from the sterilization equipment. The control structure 900 is located on the side of the weighing platform 500 facing the crushing equipment. The control structure 900 is used to control the automatic dumping of medical waste in the hopper to the feed inlet of the crusher.

[0051] Furthermore, the weighing platform 500 includes two first crossbeams 510 extending along the length of the weighing platform 500; The translation structure 700 includes a translation slide 710, which is suspended and slidably mounted on two first crossbeams 510; The assembly structure 600 includes an assembly bracket 610, which is located outside the two first crossbeams 510 and is slidably mounted on the first crossbeams 510. The assembly bracket 610 is fixedly connected to the translation slide 710.

[0052] There are two assembly brackets 610, which slide on the corresponding first crossbeams 510 respectively. The area between the two first crossbeams 510 is the inner area, and the two assembly brackets 610 are outside the two first crossbeams 510. Specifically, an auxiliary crossbeam parallel to the first crossbeam 510 is supported above the first crossbeam 510, and the assembly brackets 610 slide on the auxiliary crossbeam. The translational slide 710 is connected to the first crossbeam 510 via a first slider and slides along the length of the weighing platform 500 on the first crossbeam 510. The first slider is groove-shaped and is fastened to the first crossbeam 510 with the groove opening facing upwards. The translational slide 710 is fixedly connected to the bottom wall of the groove of the first slider. Figure 8 As shown, the length direction of the weighing platform 500 is the left-right direction; The assembly bracket 610 is connected to the auxiliary crossbeam via the second slider and slides on the auxiliary crossbeam along the length of the weighing platform 500. The second slider is groove-shaped and is fastened to the auxiliary crossbeam with the groove facing downward. The arrangement of the first slider and the second slider improves the stability and smoothness of the sliding of the translation slide 710 and the assembly bracket 610.

[0053] Furthermore, the assembly bracket 610 has a sliding part 620 and a support part 630 that are distributed vertically on one side facing the first crossbeam 510. The sliding part 620 is slidably disposed on the first crossbeam 510; The side of the translation slide 710 near the entry end of the weighing platform 500 is fixed to the support part 630.

[0054] The sliding part 620 is provided on the bottom wall of the groove that supports and is fixed to the second slider; the translation slide 710 is clamped between the first slider and the support part 630, which increases the stability of the movement of the translation slide 710 and the assembly bracket 610.

[0055] Furthermore, a second crossbeam 520 parallel to the first crossbeam 510 is provided on one side; The side of the translation slide 710 away from the weighing platform 500 is slidably mounted on the second crossbeam 520 via the sliding member 720; A first driving component 750 is connected to the sliding component 720, and the first driving component 750 is a driving cylinder 7501; The second crossbeam 520 is positioned higher than the first crossbeam 510, and the two first crossbeams 510 are located between the two second crossbeams 520; The sliding member 720 enables a sliding connection between the translation carriage 710 and the second crossbeam 520, and the sliding member 720 also provides a fixing part for the drive cylinder 7501; Specifically, the sliding component 720 has a plate-like structure and is groove-shaped; The sliding member 720 is fastened to the second crossbeam 520 with the slot facing downwards; The end of one sidewall of the sliding member 720 protrudes outward from the groove to form a first fixing part 730 that fits against and is fixedly connected to the bottom of the translational slide 710; The other sidewall of the sliding member 720 protrudes outward to form a second fixing part 740 that is fixedly connected to the first driving member 750.

[0056] The slider 720 slides on the second crossbeam 520 via the third slider, which is groove-shaped and engages with the second crossbeam 520 with the groove facing downwards; specifically, the slider 720 engages with the third slider with the groove facing downwards. The drive cylinder 7501 extends along the length of the weighing platform 500. The drive cylinder 7501 is located outside the two second crossbeams 520, and the output end of the drive cylinder 7501 is fixedly connected to the second fixed part 740.

[0057] The assembly structure 600 also includes an assembly gear set 640 and a second drive component 650;

[0058] Two sets of assembly gear groups 640 are provided, each corresponding to a group of brackets. The assembly gear group 640 includes several vertically meshing assembly gears. The assembly gears rotate along the length of the weighing platform. The assembly gear at the bottom is connected to the second drive unit 650, which is used to control the rotation of the assembly gear. The assembly gear at the top meshes with the rack 6 at the bottom of the hopper.

[0059] Additionally, a second drive unit 650 is mounted at the bottom of the translation slide 710. The second drive unit 650 includes a servo motor 6501, a reducer, and a universal joint coupling connected in sequence. The output end of the universal joint coupling is connected to the lowest assembled gear. The servo motor 6501 drives the assembled gear to rotate, thereby moving the hopper onto the weighing platform 500 through meshing with the rack 8 of the hopper. Multiple sets of assembled gears 640 can be connected simultaneously via the universal joint coupling.

[0060] The docking structure 800 includes a docking support 810, a docking rod 830, and a docking flange 820.

[0061] The docking support 810 is installed on the side of the translation slide 710 facing the entry end of the weighing platform 500, that is, the side of the translation slide 710 facing the discharge port of the sterilization equipment. The docking rod 830 is installed on the docking support 810 and is used to insert into the docking hole on the sterilization equipment. The docking flange 820 is installed on the docking support 810 and is used to connect with the electromagnetic clutch 9203 on the sterilization equipment.

[0062] When the drive cylinder 7501 moves the translation slide 710 close to the inlet of the weighing platform, that is, close to the outlet of the sterilization equipment, the docking rod 830 is first gradually inserted into the docking hole of the sterilization equipment. Finally, the docking flange 820 is connected to the electromagnetic clutch 9203 on the sterilization equipment. The electromagnetic clutch 9203 can keep the connection between the translation slide 710 and the sterilization equipment stable and uninterrupted, ensuring a stable connection environment for the meshing transmission of the gears and the rack of the hopper in the subsequent assembly.

[0063] After the hopper moves to the weighing platform 500, the docking flange 820 and the electromagnetic clutch 9203 are disconnected. The translation slide 710 moves away from the sterilization equipment and back to its original position. Then, the drive assembly gear continues to rotate, causing the hopper to move to the control structure 900. The dumping of medical waste in the hopper is controlled by the control structure 900.

[0064] To ensure smoother movement of the hopper on the weighing platform 500, a receiving slide rod 530 is installed on the top of the weighing platform 500, which slides horizontally with the bottom of the hopper. A limiting guide rail 540, arranged along the length of the weighing platform 500, is located on the top of the receiving slide rod 530. A guide wheel assembly 9 is slidably connected within the limiting guide rail 540. Multiple sets of guide wheels are installed on the side wall of the hopper basket 1 and spaced apart along the length of the hopper. The end of the limiting guide rail 540 facing the sterilization equipment is closed, thereby limiting the sliding distance of the hopper.

[0065] The guide wheel assembly 9 includes rollers 91 and guide arc blocks 92. The rollers 91 are vertically arranged and rotatably mounted on the hopper basket 1. The guide arc blocks 92 are mounted on the hopper basket 1, and the end face facing away from the hopper basket 1 is an outwardly convex arc surface. Multiple sets of roller assemblies are arranged at intervals along their own trajectory within the limiting guide rail 540. Each roller assembly includes two rollers arranged in parallel and rotating. The arc surface of the guide arc block 92 slides against the peripheral wall of the roller.

[0066] As the hopper enters the weighing platform 500, the bottom of the hopper rolls on the receiving slide bar 530. The guide block 92 and the roller 91 both enter the limiting guide rail 540. The roller 91 can reduce the friction between the hopper and the receiving slide bar 530. When the guide block 92 moves, it will contact the peripheral wall of the roller. As the guide block 92 moves, the roller will roll, thereby completing the limiting guidance while further reducing the friction with the hopper and reducing the load on the drive assembly gear and rack.

[0067] The control structure 900 includes a first control member 910 for controlling the opening of the hopper door and a second control member 920 for controlling the movement of the push plate inside the hopper in a direction close to the door. The first control member 910 is located on the side of the second control member 920 close to the assembly structure 600.

[0068] First, the door panel is opened by the first control component 910, and then the push plate 3 inside the hopper is moved along the direction close to the door panel 2 by the second control component 920, thereby pushing the medical waste away from the hopper. The door panel is directly facing the feed inlet of the crushing equipment, thus completing the dumping of the medical waste.

[0069] The first control component 910 includes a first bracket 9101 and a first insertion rod 9102. The first bracket 9101 is mounted on the weighing platform 500 and the first insertion rod 9102 is mounted on the first bracket 9101. The first insertion rod 9102 has an insertion hole 9103 at one end facing the entry end of the weighing platform 500 for horizontally inserting a control slide rod that passes through the side wall of the feeding hopper. The first bracket 9101 is located outside the weighing platform 500 and is positioned higher than the limiting guide rail 540. The movement of the push plate inside the hopper is controlled by a control slide rod extending from the side wall of the hopper. When the control slide rod slides away from the door panel, the door panel opens. As the hopper approaches the first control component 910, the control slide rod on the hopper slides into the insertion hole 9103 and abuts against the wall of the insertion hole 9103. As the hopper continues to move, the control slide rod slides away from the door panel relative to the hopper, and the door panel opens until the hopper moves to abut against the closed end of the limit guide rail 540.

[0070] Additionally, the second control component 920 includes a second bracket 9201, a control motor 9202, and an electromagnetic clutch 9203. The second bracket 9201 is mounted on the weighing platform 500, the control motor 9202 is mounted on the second bracket 9201 and its output shaft is connected to the electromagnetic clutch 9203. The electromagnetic clutch 9203 is used to dock with the flange on the linear guide rail of the hopper. The second bracket 9201 is located outside the weighing platform 500 and is positioned higher than the limit slide rail. The electromagnetic clutch contacts the flange, which is connected to the synchronous pulley via a drive shaft. The synchronous pulley is mounted on the four corner columns of the hopper. Under the operation of motor 9202, the synchronous belt drives the push plate 3 to move closer to the door plate 2, facilitating the pushing of medical waste into the feed inlet of the crushing equipment. Before pushing the medical waste out of the hopper and before the hopper enters the weighing platform, the lifting support 400 needs to adjust the height of the weighing platform 500. To determine the weight of the medical waste in the hopper, a weighing sensor can be installed between the weighing platform 500 and the lifting support 400 to record the weight of the medical waste each time it is crushed.

[0071] The implementation principle of the hopper transfer device in this embodiment of the invention is as follows: When the sterilization equipment transports the hopper carrying medical waste to the discharge port, the lifting bracket 400 controls the docking structure 800 to be horizontally aligned with the docking interface facing the sterilization equipment. The translation structure 700 drives the docking structure 800 and the assembly structure 600 to approach the sterilization equipment together until the docking structure 800 contacts and connects to the sterilization equipment. Then, the assembly structure 600 drives the hopper located at the discharge port to move horizontally to the weighing platform 500. Subsequently, the docking structure 800 disconnects from the sterilization equipment, and the translation structure 700 controls the docking structure 800 and the assembly structure 600 to move away from the sterilization equipment. Afterward, the assembly structure 600 continues to drive the hopper to move towards the control structure 900 until it contacts the control structure 900. The control structure 900 controls the medical waste in the hopper to be automatically poured into the feed port of the crushing equipment. The entire process does not require operators to approach the hopper and the weighing platform, thereby reducing the number of times operators come into contact with medical waste during medical waste transfer and reducing the risk of infection and high-temperature burns to operators during the transfer process.
