Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, and in particular to a waste transfer station compression system with safety protection functions. Background Technology

[0002] Waste transfer stations are key nodes connecting the source of waste generation with end-of-life treatment facilities. They mainly undertake the functions of centralized temporary storage and transfer transportation of waste. Their core role is to concentrate scattered small wastes at the station, reduce the volume of waste through compression and other treatments, and then transfer them to end-of-life treatment facilities by large transport vehicles. This avoids small collection vehicles frequently traveling back and forth to the end-of-life facilities, thereby improving transportation efficiency and reducing costs.

[0003] Existing waste transfer station compression systems, such as the invention patent disclosed in authorization announcement number CN118927697B, still have the following problems. Due to the structural limitations of the storage frame, both the actual pouring of waste to be compressed and the output of compressed waste must be carried out from the same side of the equipment, that is, the loading and unloading stations overlap. This means that the waste dumping truck for dumping waste to be compressed and the waste transfer truck for transferring compressed waste must queue up from one side of the equipment, which is difficult to apply in practice. In addition, the output of compressed waste still requires manual operation, which is too inconvenient in actual use.

[0004] Therefore, it is necessary to invent a waste transfer station compression system with safety protection functions to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a waste transfer station compression system with safety protection functions, which can avoid the need for waste dumping trucks and waste transfer trucks to queue up alternately, thereby reducing the difficulty of practical application. In addition, after compression, it can actively output block waste, saving manpower and making it more convenient to use. This solves the problem mentioned in the background art, where due to the structural limitations of the storage frame, both the actual dumping of waste to be compressed and the output of compressed waste must be carried out on the same side of the equipment, that is, the loading and unloading stations overlap. This means that waste dumping trucks dumping waste to be compressed and waste transfer trucks transferring compressed waste must queue up sequentially on one side of the equipment, which is difficult to apply in practice. In addition, the output of compressed waste still requires manual operation, which is too inconvenient in actual use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a garbage transfer station compression system with safety protection function, including a switching mechanism, the front of the switching mechanism being a feeding station for garbage to be compressed, the back of the switching mechanism being a discharging station for compressed garbage, two sets of symmetrically arranged receiving and lifting mechanisms being fixedly installed on the top of the switching mechanism, a blocking and protective mechanism fixed to the top of the switching mechanism being provided on the outer side of the receiving and lifting mechanism, and a compression leveling mechanism and an eccentric ejection mechanism being fixedly provided on the inner side of the blocking and protective mechanism;

[0008] Preferably, any set of the receiving and lifting mechanisms includes a receiving box fixedly installed on the top of the fixed base, the receiving box having a receiving groove in the middle of its inner side, and guide channels on both sides of the top of the receiving box.

[0009] Preferably, the receiving and lifting mechanism further includes a U-shaped frame that is slidably disposed in the inner side of the receiving groove in the vertical direction. Guide rods are fixedly disposed through both ends of the top of the receiving box in the vertical direction. Any one of the guide rods is slidably disposed in the inner side of the adjacent guide channel in the vertical direction. Limiting pins are slidably disposed through both sides of the U-shaped frame in the horizontal direction. An inclined surface is opened at the inner end of the limiting pin. A return spring A is sleeved on the outer side of the limiting pin and fixedly connected between the guide rod and the limiting pin.

[0010] Preferably, the blocking and protective mechanism includes a fixed frame fixedly disposed on the top rear side of the fixed base, and a blocking frame is fixedly disposed on the top inner side of the fixed frame.

[0011] Preferably, the blocking and protection mechanism further includes an infrared sensor and a hyperspectral camera fixedly installed inside the fixed frame, and a control cabinet fixedly installed on the top of the fixed frame. The infrared sensor and the hyperspectral camera are both electrically connected to the control cabinet.

[0012] Preferably, the compression leveling mechanism includes four hydraulic cylinders fixedly installed on the top inner side of the fixed frame. The bottom ends of the four hydraulic cylinders are fixedly connected to a pressure plate. A movable disc is rotatably nested at the bottom of the pressure plate through a bearing. A cross groove is opened at the bottom of the movable disc. A cross push rod is slidably installed on the inner side of the cross groove in the vertical direction. Multiple return springs B are fixedly connected between the inner wall of the cross groove and the top of the cross push rod.

[0013] Preferably, the compression leveling mechanism further includes a screw A that passes through the pressure plate in the vertical direction and is fixedly connected to the movable disc. A threaded sleeve A is provided on the outer side of the screw A, and the threaded sleeve A is fixedly disposed at the center of the top of the fixed frame.

[0014] Preferably, the eccentric ejection mechanism includes a screw B that is rotatably nested inside the bottom of the fixed frame via a bearing, an eccentric wheel is fixedly sleeved at the bottom outer side of the screw B, and a threaded sleeve B is drivenly sleeved at the middle outer side of the screw B.

[0015] Preferably, the eccentric ejection mechanism further includes a lifting frame that slides vertically through the fixed frame, the lifting frame being fixedly sleeved on the outside of the threaded sleeve B, and a return spring C being fixedly connected between the lifting frame and the fixed frame.

[0016] Preferably, it also includes a method for using a waste transfer station compression system with safety protection functions, the method specifically including the following steps:

[0017] S1. The garbage dumping truck dumps the garbage to be compressed into the inner side of the adjacent container from the loading station. Then, the stepper motor drives the drive gear to rotate. When the drive gear rotates, it drives the turntable to rotate through the driven gear ring, thereby causing the two containers to switch positions. At this time, the container containing the garbage to be compressed rotates to the position directly below the compression and leveling mechanism, while the empty container moves to the loading station to wait for loading.

[0018] S2. The hydraulic pump station connected to the four hydraulic cylinders drives the four hydraulic cylinders to move down synchronously. When the hydraulic cylinders move down, they drive the pressure plate to move down synchronously. When the pressure plate moves down, it drives the movable disc to move down synchronously. The movable disc drives the screw A to move down continuously inside the threaded sleeve A. During this process, the screw A drives the movable disc to rotate continuously at the bottom of the pressure plate due to the action of the threaded sleeve A. When the movable disc rotates, it drives the cross push rod to rotate synchronously.

[0019] S3. As the pressure plate continues to descend, it gradually enters the inner side of the adjacent container and contacts the inner end of the limit pin. At this time, the pressure plate pushes the limit pin through the inclined surface of the inner end of the limit pin, thereby stretching the return spring A and moving it outward to avoid the pressure plate. Then, the continuously rotating cross push rod contacts the relatively protruding garbage inside the container and pushes it, thereby making the garbage inside the container flat.

[0020] S4. After the garbage inside the container is leveled, due to the continued downward movement of the pressure plate and the obstruction of the garbage, the cross push rod compresses the return spring B and is stored inside the cross groove. Then the pressure plate continuously pressurizes the garbage until the garbage compression is completed.

[0021] S5. The hydraulic pump station connected to the four hydraulic cylinders drives the four hydraulic cylinders to move upward synchronously. When the hydraulic cylinders move upward, they drive the pressure plate to move upward synchronously until the top of the pressure plate is in contact with the bottom of the limit pin. At this time, as the pressure plate continues to move upward, the limit pin drives the guide rod to move upward synchronously inside the receiving groove. At this time, the blocky compressed waste inside the receiving box moves upward synchronously under the drive of the U-shaped frame.

[0022] S6. When the bottom surface of the blocky compressed waste is flush with the top surface of the container, the pressure plate returns to its initial position. At this time, the top surface of the pressure plate is in contact with the bottom surface of the lifting frame. As the pressure plate continues to move upward, the lifting frame drives the threaded sleeve B to move upward synchronously outside the screw B. At this time, the screw B drives the eccentric wheel to push the blocky compressed waste, making it move towards the garbage truck. At the same time, due to the continued upward movement of the U-shaped frame, the blocky compressed waste eventually slides into the garbage truck and is collected due to the change in the center of gravity.

[0023] S7. As the U-shaped frame continues to move upward, the inclined surface of the inner end of the limiting pin contacts the bottom of the blocking frame. Subsequently, as the U-shaped frame continues to move upward, the blocking frame pushes the limiting pin outward through the inclined surface of the inner end of the limiting pin until the top of the pressure plate is attached to the bottom of the blocking frame. At this time, under the action of gravity and the guiding action of the guide channel and guide rod, the U-shaped frame slides down into the inner side of the receiving groove to reset. At the same time, the hydraulic cylinder drives the pressure plate to descend to reset.

[0024] S8. The stepper motor drives the drive gear to rotate again, thereby causing the two containers to switch positions. The container holding the waste to be compressed rotates to the position directly below the compression and leveling mechanism, while the empty container moves to the feeding station to wait for feeding.

[0025] The technical effects and advantages of this invention are as follows:

[0026] This invention incorporates a switching mechanism to allow for the switching of the positions of the two sets of receiving and lifting mechanisms after loading and unloading. This enables the garbage dumping truck and the garbage transfer truck to dump the garbage to be compressed and transfer the compressed garbage from the front and back of the device, respectively. Furthermore, after garbage compression, the resetting compression leveling mechanism drives the receiving and lifting mechanisms to move the blocky garbage upwards, and the compression leveling mechanism drives the eccentric ejection mechanism. This allows the eccentric ejection mechanism to actively transport the blocky garbage in conjunction with the receiving and lifting mechanisms. Compared to existing technologies, this invention avoids the need for garbage dumping trucks and garbage transfer trucks to queue alternately, thus reducing the difficulty of practical application. Additionally, it can actively output the blocky garbage after compression, saving manpower and making it more convenient to use. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] This invention provides, for example Figures 1-5 The waste transfer station compression system shown includes a switching mechanism 1. The front of the switching mechanism 1 is the feeding station for the waste to be compressed, and the back of the switching mechanism 1 is the unloading station for the compressed waste. Two sets of symmetrically arranged receiving and lifting mechanisms 2 are fixedly installed on the top of the switching mechanism 1. A blocking and protective mechanism 3 is fixed to the top of the switching mechanism 1 on the outer side of the subsequent receiving and lifting mechanism 2. A compression leveling mechanism 4 and an eccentric ejection mechanism 5 are fixedly installed on the inner side of the blocking and protective mechanism 3.

[0036] like Figure 2As shown, the shifting mechanism 1 includes a fixed base 11. A turntable 12 is rotatably nested on the top of the fixed base 11 via a bearing. A driven gear ring 13 is fixedly sleeved on the bottom outer side of the turntable 12. A mounting bracket 14 is fixedly mounted on one corner of the top of the fixed base 11. A stepper motor 15 is fixedly mounted on the top of the mounting bracket 14. The output shaft of the stepper motor 15 passes through the top of the mounting bracket 14 and extends to the inner side of the mounting bracket 14, and is fixedly connected to a drive gear 16 that meshes with the driven gear ring 13.

[0037] By setting up the above structure, the garbage dumping truck can dump the garbage to be compressed into the inner side of the adjacent container 21 from the loading station. Then, the stepper motor 15 drives the drive gear 16 to rotate. When the drive gear 16 rotates, it drives the turntable 12 to rotate through the driven gear ring 13, thereby causing the two container 21 to switch positions. At this time, the container 21 containing the garbage to be compressed rotates to the position directly below the compression and leveling mechanism 4, while the empty container 21 moves to the loading station to wait for loading.

[0038] like Figure 3 As shown, any set of receiving and lifting mechanisms 2 includes a receiving box 21 fixedly installed on the top of the fixed base 11. A receiving groove 22 is opened in the middle of the inner side of the receiving box 21. Guide channels 23 are opened on both sides of the top of the receiving box 21. The receiving and lifting mechanism 2 also includes a U-shaped frame 24 that is slidably installed in the inner side of the receiving groove 22 in the vertical direction. Guide rods 25 are fixedly installed through both ends of the top of the receiving box 21 in the vertical direction. Any one of the guide rods 25 is slidably installed in the inner side of the adjacent guide channel 23 in the vertical direction. Limiting pins 26 are slidably installed through both sides of the U-shaped frame 24 in the horizontal direction. An inclined surface is opened at the inner end of the limiting pin 26. A return spring A27 is fixedly connected between the guide rod 25 and the limiting pin 26 and sleeved on the outer side of the limiting pin 26.

[0039] like Figure 4 As shown, the blocking and protective mechanism 3 includes a fixed frame 31 fixedly installed on the top rear side of the fixed base 11, and a blocking frame 32 fixedly installed on the top inner side of the fixed frame 31.

[0040] By setting up the aforementioned lifting mechanism 2 and blocking protection mechanism 3, when the pressure plate 42 gradually enters the inner side of the adjacent receiving box 21 and contacts the inner end of the limiting pin 26, the pressure plate 42 pushes the limiting pin 26 through the inclined surface of the inner end of the limiting pin 26, thereby causing the limiting pin 26 to stretch the return spring A27 and move outward to avoid the pressure plate 42. Subsequently, the pressure plate 42 moves upward until the top of the pressure plate 42 is in contact with the bottom of the limiting pin 26. As the pressure plate 42 continues to move upward, the limiting pin 26 drives the guide rod 25 to move upward synchronously inside the receiving groove 22. At this time, the contents of the receiving box 21 are... The blocky compressed waste moves upward synchronously under the drive of the U-shaped frame 24. As the U-shaped frame 24 continues to move upward, the inclined surface of the inner end of the limiting pin 26 contacts the bottom of the blocking frame 32. Subsequently, as the U-shaped frame 24 continues to move upward, the blocking frame 32 pushes the limiting pin 26 outward through the inclined surface of the inner end of the limiting pin 26 until the top of the pressure plate 42 is attached to the bottom of the blocking frame 32. At this time, under the action of gravity and the guiding action of the guide channel 23 and the guide rod 25, the U-shaped frame 24 slides down into the inner side of the receiving groove 22 to reset, thus eliminating the need for manual reset or a separate drive device for reset.

[0041] like Figure 5 As shown, the compression leveling mechanism 4 includes four hydraulic cylinders 41 fixedly installed on the top inner side of the fixed frame 31. The bottom ends of the four hydraulic cylinders 41 are fixedly connected to a pressure plate 42. A movable disc 43 is nested at the bottom of the pressure plate 42 via a bearing. A cross groove 44 is opened at the bottom of the movable disc 43. A cross push rod 45 is slidably installed on the inner side of the cross groove 44 in the vertical direction. Multiple return springs B46 are fixedly connected between the inner wall of the cross groove 44 and the top of the cross push rod 45. The compression leveling mechanism 4 also includes a screw A47 that passes through the pressure plate 42 in the vertical direction and is fixedly connected to the movable disc 43. A threaded sleeve A48 is driven sleeved on the outer side of the screw A47. The threaded sleeve A48 is fixedly installed at the center of the top of the fixed frame 31.

[0042] By setting up the above structure, the hydraulic pump station connected to the four hydraulic cylinders 41 can drive the four hydraulic cylinders 41 to move down synchronously. When the hydraulic cylinders 41 move down, they drive the pressure plate 42 to move down synchronously. When the pressure plate 42 moves down, it drives the movable disc 43 to move down synchronously. The movable disc 43 then drives the screw A47 to move down continuously inside the threaded sleeve A48. During this process, the screw A47 drives the movable disc 43 to rotate continuously at the bottom of the pressure plate 42 due to the action of the threaded sleeve A48. When the movable disc 43 rotates, it drives the cross push rod 45 to rotate synchronously. As the pressure plate 42 continues to descend, the continuously rotating cross push rod 45 contacts and pushes the relatively protruding garbage inside the container 21, thereby flattening the garbage inside the container 21 and avoiding uneven pressure caused by local protrusions. After the garbage inside the container 21 is flattened, due to the continued downward movement of the pressure plate 42 and the obstruction of the garbage, the cross push rod 45 compresses the return spring B46 and is stored inside the cross groove 44. Then the pressure plate 42 continuously pressurizes the garbage until the garbage compression is completed.

[0043] like Figure 4 As shown, the eccentric ejection mechanism 5 includes a screw B51 that is rotatably nested inside the bottom of the fixed frame 31 via a bearing. An eccentric wheel 52 is fixedly sleeved at the bottom outer end of the screw B51. A threaded sleeve B53 is drivenly sleeved at the middle outer part of the screw B51. The eccentric ejection mechanism 5 also includes a lifting frame 54 that slides vertically through the fixed frame 31. The lifting frame 54 is fixedly sleeved on the outside of the threaded sleeve B53. A return spring C55 is fixedly connected between the lifting frame 54 and the fixed frame 31.

[0044] By setting up the above structure, after the top surface of the pressure plate 42 is in contact with the bottom surface of the lifting frame 54, as the pressure plate 42 continues to move upward, the lifting frame 54 drives the threaded sleeve B53 to move upward synchronously outside the screw B51. At this time, the screw B51 drives the eccentric wheel 52 to push the blocky compressed waste, making it move closer to the garbage truck. At the same time, due to the continued upward movement of the U-shaped frame 24, the blocky compressed waste eventually slides into the garbage truck and is collected due to the change in the center of gravity. Compared with the existing technology of manually outputting blocky compressed waste, this invention significantly saves manpower while using a combination of active pushing and gravity to output blocky waste. It can also reduce the active pushing stroke, eliminating the need to push the blocky waste too far, thereby reducing the complexity of the equipment and the cost of use.

[0045] This invention also discloses a method for using a waste transfer station compression system with safety protection functions, the method specifically including the following steps:

[0046] S1. The garbage dumping truck dumps the garbage to be compressed into the inner side of the adjacent container 21 from the loading station. Then, the stepper motor 15 drives the drive gear 16 to rotate. When the drive gear 16 rotates, it drives the turntable 12 to rotate through the driven gear ring 13, thereby causing the two containers 21 to switch positions. At this time, the container 21 containing the garbage to be compressed rotates to the position directly below the compression and leveling mechanism 4, while the empty container 21 moves to the loading station to wait for loading.

[0047] S2. The hydraulic pump station connected to the four hydraulic cylinders 41 drives the four hydraulic cylinders 41 to move down synchronously. When the hydraulic cylinders 41 move down, they drive the pressure plate 42 to move down synchronously. When the pressure plate 42 moves down, it drives the movable disc 43 to move down synchronously. The movable disc 43 drives the screw A47 to move down continuously inside the threaded sleeve A48. During this process, the screw A47 drives the movable disc 43 to rotate continuously at the bottom of the pressure plate 42 due to the action of the threaded sleeve A48. When the movable disc 43 rotates, it drives the cross push rod 45 to rotate synchronously.

[0048] S3. As the pressure plate 42 continues to descend, it gradually enters the inner side of the adjacent container 21 and contacts the inner end of the limiting pin 26. At this time, the pressure plate 42 pushes the limiting pin 26 through the inclined surface of the inner end of the limiting pin 26, thereby stretching the limiting pin 26 on the return spring A27 and moving it outward to avoid the pressure plate 42. Then, the continuously rotating cross push rod 45 contacts the relatively protruding garbage inside the container 21 and pushes it, thereby making the garbage inside the container 21 stacked flat and avoiding uneven pressure caused by local protrusion.

[0049] S4. After the garbage inside the container 21 is leveled, due to the continued downward movement of the pressure plate 42 and the obstruction of the garbage, the cross push rod 45 compresses the return spring B46 and is stored inside the cross groove 44. Then the pressure plate 42 continuously pressurizes the garbage until the garbage compression is completed.

[0050] S5. The hydraulic pump station connected to the four hydraulic cylinders 41 drives the four hydraulic cylinders 41 to move upward synchronously. When the hydraulic cylinders 41 move upward, they drive the pressure plate 42 to move upward synchronously until the top of the pressure plate 42 is in contact with the bottom of the limit pin 26. At this time, as the pressure plate 42 continues to move upward, the limit pin 26 drives the guide rod 25 to move upward synchronously inside the receiving groove 22. At this time, the blocky compressed waste inside the receiving box 21 moves upward synchronously under the drive of the U-shaped frame 24.

[0051] S6. When the bottom surface of the blocky compressed waste is flush with the top surface of the container 21, the pressure plate 42 returns to its initial position. At this time, the top surface of the pressure plate 42 is in contact with the bottom surface of the lifting frame 54. As the pressure plate 42 continues to move upward, the lifting frame 54 drives the threaded sleeve B53 to move upward synchronously outside the screw B51. At this time, the screw B51 drives the eccentric wheel 52 to push the blocky compressed waste, making it move towards the garbage truck. At the same time, due to the continued upward movement of the U-shaped frame 24, the blocky compressed waste eventually slides into the garbage truck and is collected due to the change in the center of gravity.

[0052] S7. As the U-shaped frame 24 moves upward, the inclined surface of the inner end of the limiting pin 26 contacts the bottom of the blocking frame 32. Subsequently, as the U-shaped frame 24 continues to move upward, the blocking frame 32 pushes the limiting pin 26 outward through the inclined surface of the inner end of the limiting pin 26 until the top of the pressure plate 42 is attached to the bottom of the blocking frame 32. At this time, under the action of gravity and the guiding action of the guide channel 23 and the guide rod 25, the U-shaped frame 24 slides down into the inner side of the receiving groove 22 to reset. At the same time, the hydraulic cylinder 41 drives the pressure plate 42 to descend to reset.

[0053] S8. The stepper motor 15 drives the drive gear 16 to rotate again, thereby causing the two containers 21 to switch positions. The container 21 containing the waste to be compressed rotates to be directly below the compression and leveling mechanism 4, while the empty container 21 moves to the feeding station to wait for feeding.

[0054] Example 2

[0055] Unlike the embodiments described above, as Figure 4 As shown, the blocking and protection mechanism 3 also includes an infrared sensor 33 and a hyperspectral camera 34 fixedly installed inside the fixed frame 31, and a control cabinet 35 fixedly installed on the top of the fixed frame 31. The infrared sensor 33 and the hyperspectral camera 34 are both electrically connected to the control cabinet 35, and the hydraulic pump station and the stepper motor 15 are also electrically connected to the control cabinet 35.

[0056] The specific protection logic is as follows: the infrared sensor 33 identifies human bodies and waste through temperature differences, and the hyperspectral camera 34 distinguishes human bodies (skin, clothing) and waste materials through spectral features; the two transmit signals to the control cabinet 35. If human characteristics are detected in the preset danger area (such as the compression area or the pushing area), the control cabinet 35 immediately triggers the hydraulic pump station and the stepper motor 15 to stop, so as to avoid mechanical action causing injury to personnel.

[0057] It should be noted that the infrared sensor 33, hyperspectral camera 34 and control cabinet 35 mentioned above are well known technologies to those skilled in the art, therefore, this application will not elaborate on the models and specific principles of the above structures here.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

10. A garbage transfer station compression system with safety protection function according to claim 9, characterized in that, It also includes a method for using a waste transfer station compression system with safety protection functions, the method specifically including the following steps: S1. The garbage dumping truck dumps the garbage to be compressed into the inner side of the adjacent container (21) from the loading station. Then the stepper motor (15) drives the drive gear (16) to rotate. When the drive gear (16) rotates, it drives the turntable (12) to rotate through the driven gear ring (13), thereby causing the two containers (21) to switch positions. At this time, the container (21) containing the garbage to be compressed rotates to the direct under the compression leveling mechanism (4), and the empty container (21) moves to the loading station to wait for loading. S2. The hydraulic pump station connected to the four hydraulic cylinders (41) drives the four hydraulic cylinders (41) to move down synchronously. When the hydraulic cylinders (41) move down, they drive the pressure plate (42) to move down synchronously. When the pressure plate (42) moves down, it drives the movable disc (43) to move down synchronously. The movable disc (43) then drives the screw A (47) to move down continuously inside the threaded sleeve A (48). During this process, the screw A (47) drives the movable disc (43) to rotate continuously at the bottom of the pressure plate (42) due to the action of the threaded sleeve A (48). When the movable disc (43) rotates, it drives the cross push rod (45) to rotate synchronously. S3. As the pressure plate (42) continues to descend, the pressure plate (42) gradually enters the inner side of the adjacent container (21) and contacts the inner end of the limiting pin (26). At this time, the pressure plate (42) pushes the limiting pin (26) through the inclined surface of the inner end of the limiting pin (26), thereby causing the limiting pin (26) to stretch the return spring A (27) and move outward to avoid the pressure plate (42). Then, the continuously rotating cross push rod (45) contacts the relatively protruding garbage inside the container (21) and pushes it, thereby making the garbage inside the container (21) stacked flat. S4. After the garbage inside the container (21) is leveled, due to the continued downward movement of the pressure plate (42) and the obstruction of the garbage, the cross push rod (45) compresses the return spring B (46) and is stored in the inside of the cross groove (44). Then the pressure plate (42) continuously pressurizes the garbage until the garbage compression is completed. S5. The hydraulic pump station connected to the four hydraulic cylinders (41) drives the four hydraulic cylinders (41) to move upward synchronously. When the hydraulic cylinders (41) move upward, they drive the pressure plate (42) to move upward synchronously until the top of the pressure plate (42) is in contact with the bottom of the limit pin (26). At this time, as the pressure plate (42) continues to move upward, the limit pin (26) drives the guide rod (25) to move upward synchronously inside the receiving groove (22). At this time, the blocky compressed garbage inside the receiving box (21) moves upward synchronously under the drive of the U-shaped frame (24). S6. When the bottom surface of the blocky compressed waste is flush with the top surface of the container (21), the pressure plate (42) returns to its initial position. At this time, the top surface of the pressure plate (42) is in contact with the bottom surface of the lifting frame (54). As the pressure plate (42) continues to move upward, the lifting frame (54) drives the threaded sleeve B (53) to move upward synchronously outside the screw B (51). At this time, the screw B (51) drives the eccentric wheel (52) to push the blocky compressed waste, causing it to move towards the garbage truck. At the same time, due to the continued upward movement of the U-shaped frame (24), the blocky compressed waste eventually slides into the garbage truck and is collected due to the change in the center of gravity. S7. As the U-shaped frame (24) moves upward, the inclined surface of the inner end of the limiting pin (26) contacts the bottom of the blocking frame (32). Subsequently, as the U-shaped frame (24) continues to move upward, the blocking frame (32) pushes the limiting pin (26) outward through the inclined surface of the inner end of the limiting pin (26) until the top of the pressure plate (42) is attached to the bottom of the blocking frame (32). At this time, under the action of gravity and the guiding action of the guide channel (23) and the guide rod (25), the U-shaped frame (24) slides down into the inner side of the receiving groove (22) to reset. At the same time, the hydraulic cylinder (41) drives the pressure plate (42) to descend to reset. S8. The stepper motor (15) drives the drive gear (16) to rotate again, thereby causing the two containers (21) to switch positions. The container (21) containing the garbage to be compressed rotates to the direct under the compression leveling mechanism (4), while the empty container (21) moves to the feeding station to wait for feeding.
