Description

Technical Field

[0001] This invention relates to the field of waste treatment equipment technology, and more specifically to a waste compression station. Background Technology

[0002] With the development of the times and the progress of science and technology, people's living standards have been continuously improved, but this has also created a problem: all kinds of garbage are generated in large quantities, especially people's daily garbage, which has caused great pollution to the surrounding environment. In order to collect and dispose of this garbage, people have invented garbage compression stations and garbage bins.

[0003] Waste compression stations are used to compress loose waste, reducing its volume. The compressed waste is then transported to waste treatment plants by transfer vehicles, reducing the number of transport trips and thus lowering transportation costs. They also remove wastewater from the waste. However, due to the inadequate layout design of existing waste compression stations and their reliance on semi-automatic control methods, many steps require human intervention during operation, increasing safety hazards and resulting in low overall operational safety. Summary of the Invention

[0004] The purpose of this invention is to provide a waste compression station that has the advantages of simple control logic, high degree of automation, and improved operational safety.

[0017] During the movement of the boom mounting bracket, the boom is controlled to flip upward so that the hook rod is engaged in the lifting groove.

[0018] In an embodiment of the present invention, the lower layer of the frame is provided with a first support column and a second support column arranged vertically. The waste compression station also includes a support beam disposed on the tipping frame and movable along the length direction of the tipping frame. The two transverse ends of the support beam are respectively formed with a first support portion and a second support portion for supporting and cooperating with the first support column and the second support column. The controller is further configured to:

[0019] Before the transfer vehicle transfers the garbage bin to the tipping frame, the support beam is positioned at the third preset position of the tipping frame so that the first support column and the second support column support the first support part and the second support part, respectively.

[0020] After the transfer vehicle transfers the garbage bin to the tipping frame, before the tipping frame flips to a vertical position, the control support beam moves to the fourth preset position of the tipping frame so that the tipping frame can flip from a horizontal state to a vertical state.

[0021] In an embodiment of the present invention, after the transfer vehicle transfers the garbage bin to the tipping frame and before the tipping frame tilts to a vertical position, controlling the support beam to move to a fourth preset position of the tipping frame, so that the tipping frame can tilt from a horizontal state to a vertical state, includes:

[0022] After the transfer vehicle transfers the garbage bin to the tipping frame, but before the tipping frame flips to a vertical position, the tipping frame is controlled to flip up at a first preset angle, the range of which is 1°-20°.

[0023] The control support beam is moved to the fourth preset position of the tilting frame so that the tilting frame can be tilted from a horizontal state to a vertical state.

[0024] In an embodiment of the present invention, the lower layer of the frame forms a garbage bin placement space for accommodating garbage bins, and the garbage compression station further includes a weighing device disposed at the bottom of the garbage bin placement space, and the controller is further configured to:

[0026] In an embodiment of the present invention, the waste compression station further includes a frame and a roller shutter door disposed on the upper layer of the frame. The roller shutter door is vertically and retractably mounted on the frame and located between the transfer platform and the hopper. A sealing strip is provided at the bottom of the roller shutter door. The controller is further configured to:

[0027] After the hopper tilts down and aligns with the inlet of the garbage bin, the roller shutter door is lowered to ensure that the sealing strip is in close contact with the side wall of the hopper near the transfer platform.

[0028] In an embodiment of the present invention, the controller is further configured to:

[0029] After the pressure head compresses the garbage in the garbage bin and the weighing device confirms that the measured weight value has been reached, the roller shutter door is controlled to rise.

[0030] Control the hopper to tilt upwards;

[0031] The control mechanism closes the top cover of the trash can;

[0032] Move the control boom mounting bracket to the second preset position of the tilting frame so that the hanging rod is engaged in the lifting groove;

[0033] Control the tilting frame to tilt upwards to a second preset angle so that the fully loaded garbage bin can be transferred to the transfer vehicle.

[0035] Control the tilting frame to tilt up to the second preset angle, the second preset angle is in the range of 90°-95°;

[0036] Control the tilting frame to tilt from the second preset angle to a horizontal position;

[0037] During the process of the tilting frame tilting from the second preset angle to the horizontal state, the control arm mounting frame is moved to the first preset position of the tilting frame, and the control support beam is moved to the third preset position of the tilting frame.

[0038] As the swing arm mounting frame moves to the first preset position, the swing arm is controlled to tilt downwards so as to transfer the fully loaded garbage bin to the transfer vehicle.

[0042] After the tipping frame flips to a horizontal position, the control panel flips to a horizontal position so that the fully loaded garbage bin can be transferred to the transfer vehicle.

[0043] In an embodiment of the present invention, the support beam and the swing arm mounting frame are connected by a connecting rod. When the swing arm mounting frame moves to the first preset position of the tilting frame, the support beam is determined to be at the third preset position of the tilting frame; when the swing arm mounting frame moves to the second preset position of the tilting frame, the support beam is determined to be at the fourth preset position of the tilting frame.

Detailed Implementation

[0071] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0072] The embodiments of the present invention provide a novel waste compression station, such as... Figure 2-4 As shown, the waste compression station includes a frame, an unloading vehicle, a transfer vehicle, a waste container 1, a pressing head moving mechanism 2, a pressing head 3, a hopper 4, a tipping device 5, and a controller. A transfer platform 11 is formed on the upper layer of the frame. Figure 7-9As shown, the tilting device 5 includes a tilting frame 501 and a tilting plate 502. The tilting plate 502 is disposed on the tilting frame 501 and is used to fill the gap between the tilting frame 501 in a horizontal state and the transfer platform 11, as shown. Figure 1 As shown, the controller is configured to perform the following steps:

[0073] Step S101: Ensure that both the tilting frame 501 and the tilting plate 502 are in a horizontal state;

[0074] Step S102: Control the transfer vehicle to transfer the garbage bin 1 onto the tipping frame 501;

[0075] Step S103: Control the flip plate 502 to flip so that it is perpendicular to the flip frame 501;

[0076] Step S104: Control the tilting frame 501 to tilt to a vertical position;

[0077] Step S105: Control the hopper 4 to tilt down and connect with the feed inlet of the garbage bin 1 from the top and bottom;

[0078] Step S106: Control the unloading vehicle to unload material into hopper 4;

[0079] Step S107: Control the pressure head moving mechanism 2 to move the pressure head 3 above the hopper 4;

[0080] Step S108: Control the pressure head 3 to compress the garbage in the garbage bin 1.

[0081] Specifically, in this embodiment, the frame (i.e., the civil structure) includes an upper layer and a lower layer. The upper layer of the frame forms unloading platforms 12 and transfer platforms 11 that are spaced longitudinally. A pressure head parking space is provided between two adjacent transfer platforms 11. The lower layer of the frame forms a garbage bin placement space 7 for placing garbage bins 1. The unloading platforms 12 and transfer platforms 11 are at the same height. The hopper 4 is rotatably set on the unloading platform 12 and can be vertically connected to the garbage bins 1 in the garbage bin placement space 7. Further, the garbage compression station in this embodiment also includes a pressure head moving track 13. The pressure head moving track 13 is set at the top of the upper layer of the frame. The pressure head moving track 13 passes laterally through the pressure head parking space and extends longitudinally to the top of the garbage bin placement space 7 of each garbage compression unit. The pressure head 3 is set in the pressure head parking space and can move along the pressure head moving track 13. The pressure head 3 can pass through the hopper 4 to compress the garbage in the garbage bin 1.

[0082] The unloading vehicle, transfer vehicle, garbage bin 1, pressing head moving mechanism 2, pressing head 3, hopper 4, and tilting device 5 are all communicatively connected to the controller. The controller controls these components by sending control signals to them. The tilting device 5 also includes a fixed frame 505, a tilting drive component 504, and a flipping plate drive component 507. One end of the tilting frame 501 is rotatably connected to the top of the fixed frame 505. The tilting drive component 504 is mounted on the fixed frame 505 and drivenly connected to the tilting frame 501. The flipping plate drive component 507 is mounted on the tilting frame 501 and drivenly connected to the flipping plate 502. Both the tilting drive component 504 and the flipping plate drive component 507 can be selected as telescopic hydraulic cylinders.

[0083] When the unloading truck carrying garbage arrives at the transfer platform 11, and the transfer truck carrying empty garbage bin 1 moves to the transfer platform 11, the controller can automatically execute steps S101-S108. Specifically, if the controller detects that the tilting drive 504 and the flipping drive 507 are both in the extended state, it can determine that the tilting frame 501 and the flipping plate 502 are in a horizontal state. Then, the controller controls the transfer truck to transfer the empty garbage bin 1 onto the tilting frame 501. After the garbage bin 1 is transferred onto the tilting frame 501, in order to reduce the overall tilting radius of the tilting frame 501 and the tilting mechanism, the controller controls the flipping plate 502 to tilt to a state perpendicular to the tilting frame 501, that is, the flipping plate 502 is in a vertical state at this time. After the flipping plate 502 has finished tilting, the controller then controls the... The tilting frame 501 tilts to a vertical position, causing the garbage bin 1 and the tilting plate 502 to tilt together. After tilting, the garbage bin 1 is in a vertical position, ready for loading garbage. After the tilting frame 501 tilts, the controller controls the hopper 4 to tilt downwards so that the discharge port of the hopper 4 and the inlet at the top of the garbage bin 1 are aligned vertically. Then, the controller controls the unloading vehicle to unload into the hopper 4, and the garbage enters the garbage bin 1 through the hopper 4. When the garbage bin 1 contains a first preset weight of garbage, the unloading vehicle is temporarily stopped, and the pressure head moving mechanism 2 is controlled to move along the pressure head moving track 13 to the top of the hopper 4 with the pressure head 3. After the pressure head moving mechanism 2 moves into position, the controller can control the pressure head 3 to pass through the hopper 4 to compress the garbage in the garbage bin 1. Since the garbage compression station in this embodiment can achieve fully automatic control, it improves the automation level of the garbage compression station, reduces manual intervention, reduces labor costs, avoids safety accidents, and improves overall operational safety.

[0084] Furthermore, to ensure sufficient tilting space for the tilting frame 501 and the garbage bin 1 as a whole, and to prevent the garbage bin 1 from colliding with the frame and causing damage, there is a certain gap between the tilting frame 501 and the transfer platform 11 when the tilting frame 501 is in a horizontal state. If the management personnel (or other operators) of the garbage compression station accidentally step into the gap and fall into the lower layer of the frame, it will lead to a safety accident. In this embodiment, when the flap 502 is in a horizontal state, it can not only fill the gap mentioned above, preventing the management personnel or operators from accidentally stepping into the gap and causing a safety accident, but also improve the safety performance of the garbage compression station. It can also prevent the garbage bin 1 from interfering with the garbage bin 1 when it is transferred to the tilting frame 501. When the tilting frame 501 tilts downward, controlling the flap 502 to tilt to a state perpendicular to the tilting frame 501 can reduce the tilting radius of the tilting frame 501 and the flap 502.

[0085] In one embodiment of the present invention, such as Figure 10-11 As shown, the garbage compression station also includes a lifting mechanism 6 disposed on the tilting frame 501. The lifting mechanism 6 includes a rotating arm mounting frame 601 movable along the length of the tilting frame 501 and a rotating arm 602 rotatably connected to the rotating arm mounting frame 601. The rotating arm 602 is provided with a lifting groove 603 for hooking a hanging rod on the side wall of the garbage bin 1. The controller is further configured to execute steps S201-S203, wherein:

[0086] Step S201: Before the transfer vehicle transfers the garbage bin 1 onto the tipping frame 501, determine that the swing arm mounting frame 601 is in the first preset position of the tipping frame 501;

[0087] Step S202: After the transfer vehicle transfers the garbage bin 1 onto the tipping frame 501, control the rotating arm mounting frame 601 to move to the second preset position of the tipping frame 501;

[0088] Step S203: During the movement of the boom mounting bracket 601, control the boom 602 to flip upward so that the hanging rod is engaged in the lifting groove 603.

[0089] Specifically, the lifting mechanism 6 also includes a lifting drive component 604, which is mounted on the rotating arm mounting bracket 601 and drivenly connected to the rotating arm 602. The lifting drive component 604 can be a telescopic hydraulic cylinder, which is used to hook or unhook the hanging rod of the garbage bin 1 by controlling its extension and retraction. The tipping frame 501 is provided with a moving track, and the left and right sides of the rotating arm mounting bracket 601 are provided with slider assemblies 605 that can move along the moving track. The tipping device 5 also includes a moving drive component 506, one end of which is connected to the tipping frame 501 and the other end of which is drivenly connected to the rotating arm mounting bracket 601. The moving drive component 506 can be a telescopic hydraulic cylinder.

[0090] Before the transfer vehicle transfers the garbage bin 1 onto the tipping frame 501, the rotating arm mounting bracket 601 is positioned at the first preset position of the tipping frame 501. When the tipping frame 501 is in a horizontal state, the first preset position is located away from its rotating connection end. After the transfer vehicle transfers the garbage bin 1 onto the tipping frame 501, the rotating arm mounting bracket 601 moves to the second preset position of the tipping frame 501 under the driving action of the moving drive component 506. During the movement of the rotating arm mounting bracket 601, the lifting drive component 604 is controlled to extend so that the rotating arm 602 flips upward. When the rotating arm mounting bracket 601 moves into place, the hanging rod of the garbage bin 1 is engaged in the lifting groove 603 to fix the garbage bin 1 and prevent the garbage bin 1 from falling off the tipping frame 501 when it is tipped.

[0091] In one embodiment of the present invention, the lower layer of the frame is provided with a first support column and a second support column arranged vertically. The waste compression station also includes a support beam 503 disposed on the tilting frame 501 and movable along the length direction of the tilting frame 501. The two transverse ends of the support beam 503 are respectively formed with a first support portion 5031 and a second support portion 5032 for supporting and cooperating with the first support column and the second support column. The controller is further configured to execute steps S301-S302, wherein:

[0092] Step S301: Before the transfer vehicle transfers the garbage bin 1 to the tipping frame 501, the support beam 503 is determined to be at the third preset position of the tipping frame 501, so that the first support column and the second support column support the first support part 5031 and the second support part 5032 respectively.

[0093] Step S302: After the transfer vehicle transfers the garbage bin 1 to the tipping frame 501, before the tipping frame 501 flips to a vertical state, the control support beam 503 is moved to the fourth preset position of the tipping frame 501 so that the tipping frame 501 can flip from a horizontal state to a vertical state.

[0094] Specifically, both the first and second support columns are civil engineering structures installed in the lower layer of the frame, possessing strong supporting force. Before the transfer vehicle transfers the garbage bin 1 onto the tipping frame 501, the controller first determines that the support beam 503 is at the third preset position of the tipping frame 501, so that the first and second support columns support the first support part 5031 and the second support part 5032 respectively. This avoids relying solely on the tipping drive component 504 to provide the force supporting the tipping frame 501 and the garbage bin 1, thereby helping to extend the service life of the tipping drive component 504. After the transfer vehicle transfers the garbage bin 1 onto the tipping frame 501, before the tipping frame 501 tilts to a vertical state, the controller controls the support beam 503 to move to the fourth preset position of the tipping frame 501, so that the first support part 5031 and the second support part 5032 move away from the first and second support columns, preventing the tipping drive component 504 from being unable to retract smoothly due to the obstruction of the first and second support columns, thus preventing the tipping frame 501 from tilting to a vertical state.

[0095] In one embodiment of the present invention, step S302: after the transfer vehicle transfers the garbage bin 1 to the tipping frame 501, but before the tipping frame 501 tilts to a vertical position, the control support beam 503 is moved to a fourth preset position of the tipping frame 501 so that the tipping frame 501 can tilt from a horizontal state to a vertical state. This further includes steps S401-S402, wherein:

[0096] Step S401: After the transfer vehicle transfers the garbage bin 1 to the tipping frame 501, before the tipping frame 501 flips to a vertical position, the tipping frame 501 is controlled to flip up to a first preset angle, the range of the first preset angle being 1°-20°.

[0097] Step S402: Control the support beam 503 to move to the fourth preset position of the tilting frame 501 so that the tilting frame 501 can be tilted from a horizontal state to a vertical state.

[0098] The controller executes steps S401-S402, which causes the first support part 5031 and the second support part 5032 to move upward and away from the first support column and the second support column, respectively. Then, the support beam 503 moves to the fourth preset position of the tilting frame 501, which avoids friction between the first support part 5031 and the second support part 5032 and the first support column and the second support column when the support beam 503 moves, thus improving the convenience of the movement of the support beam 503.

[0099] In one embodiment of the present invention, the lower layer of the frame forms a garbage bin placement space 7 for accommodating the garbage bin 1, and the garbage compression station further includes a weighing device 8 disposed at the bottom of the garbage bin placement space 7. The controller is further configured to execute step 501, wherein:

[0100] Step 501: After the tilting frame 501 is tilted to a vertical position, control the rotating arm mounting frame 601 to move to the fifth preset position of the tilting frame 501 so that the garbage bin 1 is placed on the weighing device 8.

[0101] Specifically, after the tilting frame 501 is tilted vertically into place, the control arm mounting frame 601 is moved to the fifth preset position of the tilting frame 501, so that the lifting mechanism 6 is lowered as a whole. After a certain distance, the garbage bin 1 contacts the upper part of the weighing device 8. The control mechanism 6 is then lowered further so that the hanging rod of the garbage bin 1 is disengaged from the lifting groove 603, thus ensuring the accuracy of the measurement by the weighing device 8.

[0102] In one embodiment of the present invention, the waste compression station further includes a frame 9 disposed on the upper layer of the frame and a roller shutter 10. The roller shutter 10 is vertically and elliptically disposed on the frame 9 and located between the transfer platform 11 and the hopper 4. A sealing strip 1001 is provided at the bottom of the roller shutter 10. The controller is further configured to execute step 601, wherein:

[0103] Step 601: After the hopper 4 is tilted down and aligned with the feed inlet of the garbage bin 1, control the roller shutter door 10 to descend so that the sealing strip 1001 is in close contact with the side wall of the hopper 4 near the transfer platform 11.

[0104] Specifically, the roller shutter door 10 is located on the side of the frame 9 near the transfer platform 11. The waste compression station also includes a first partition and a second partition located on the frame 9 and on the left and right sides (i.e., horizontally) of the hopper 4, as well as a top plate located on the top of the frame 9. After the hopper 4 tilts down and aligns with the inlet of the waste container 1, when the unloading vehicle is about to unload, the controller controls the roller shutter door 10 to fall, so that the sealing strip 1001 makes tight contact with the side wall of the hopper 4 near the transfer platform 11, thereby enhancing the sealing of the waste compression station during unloading, preventing waste from scattering in all directions when dumped, and reducing waste. The odor overflows during dumping; in addition, due to the large airflow generated inside the waste compression station during unloading, the sealing strip 1001 can prevent the airflow from blowing up the bottom of the roller shutter 10, causing waste or odor to leak out; furthermore, the sealing strip 1001 is made of elastic rubber. After the roller shutter 10 is lowered, the sealing part 18 abuts against the side wall of the hopper 4, and the sealing strip 1001 undergoes adaptive deformation to enhance the tight fit between it and the side wall of the hopper 4, which helps to further enhance the sealing performance of the waste compression station during unloading and further improve the environmental protection performance of the waste compression station.

[0105] In one embodiment of the invention, the controller is further configured to execute steps S701-S705, wherein:

[0106] Step S701: After the pressure head 3 compresses the garbage in the garbage bin 1 and the measurement result of the weighing device 8 reaches the preset weight value, control the roller shutter door 10 to rise.

[0107] Step S702: Control hopper 4 to tilt upwards;

[0108] Step S703: Control the lid opening mechanism to close the top cover of trash can 1;

[0109] Step S704: Control the boom mounting bracket 601 to move to the second preset position of the tilting frame 501 so that the hanging rod is engaged in the lifting groove 603;

[0110] Step S705: Control the tilting frame 501 to tilt upwards to a second preset angle so as to transfer the fully loaded garbage bin 1 to the transfer vehicle.

[0111] Specifically, the garbage bin 1 is equipped with a lid-opening mechanism connected to the control communication system. To allow garbage to enter the interior of the garbage bin 1, after the garbage bin 1 is flipped to a vertical position, the controller controls the lid-opening mechanism to perform the lid-opening operation, so that after the hopper 4 is tilted down, the discharge port of the hopper 4 and the inlet of the garbage bin 1 are vertically aligned. The weighing device 8 continuously measures the weight of the garbage bin 1. When the measurement result of the weighing device 8 reaches the second preset weight, the unloading is temporarily stopped, and then the pressure head moving mechanism 2 is controlled to move the pressure head 3 above the hopper 4 to compress the garbage in the garbage bin 1. After compression for a certain period of time... After the interval, the pressing head moving mechanism 2 drives the pressing head 3 to move out of the frame 9, and controls the unloading car to unload again. The controller controls the unloading car, the pressing head moving mechanism 2 and the pressing head 3 to repeatedly perform unloading and compression operations until the measurement result of the weighing device 8 reaches the preset weight value. Then, the controller controls the roller shutter door 10 to rise, the hopper 4 to flip up, the top cover of the garbage bin 1 to close, and the rotating arm mounting frame 601 to move to the second preset position of the tipping frame 501 to fix the garbage bin 1. Then, the controller controls the tipping frame 501 to flip up to the second preset angle so that the fully loaded garbage bin 1 can be transferred to the transfer car.

[0112] In one embodiment of the present invention, step S705: controlling the tilting frame 501 to tilt upward to a second preset angle so as to transfer the fully loaded garbage bin 1 to the transfer vehicle, further includes steps S801-S804, wherein:

[0113] Step S801: Control the tilting frame 501 to tilt upwards to the second preset angle, the range of the second preset angle is 90°-95°;

[0114] Step S802: Control the tilting frame 501 to tilt from the second preset angle to a horizontal state;

[0115] Step S803: During the process of the tilting frame 501 tilting from the second preset angle to the horizontal state, control the rotating arm mounting frame 601 to move to the first preset position of the tilting frame 501, and control the support beam 503 to move to the third preset position of the tilting frame 501.

[0116] Step S804: During the process of the rotating arm mounting frame 601 moving to the first preset position, control the rotating arm 602 to tilt down so as to transfer the fully loaded garbage bin 1 to the transfer vehicle.

[0117] Specifically, the tilting frame 501 needs to be tilted up to the second preset angle and then tilted down. During the tilting process, the control arm mounting frame 601 is moved to the first preset position of the tilting frame 501, and the control support beam 503 is moved to the third preset position of the tilting frame 501. This ensures that the first support part 5031 and the second support part 5032 can eventually stay above the first support column and the second support column, so that the first support column and the second support column can support the first support part 5031 and the second support part 5032. It also allows the lifting groove 603 to detach from the hanging rod of the garbage bin 1, releasing the fixation of the garbage bin 1, and preparing for the subsequent transfer of the fully loaded garbage bin 1 to the transfer vehicle.

[0118] In one embodiment of the present invention, the flipping device 5 further includes a flipping drive member 504 that is drivenly connected to the flipping frame 501. Step S802: controlling the flipping frame 501 to flip from the second preset angle to the horizontal state further includes steps S901-S903, wherein:

[0119] Step S901: Determine that the support beam 503 is at the third preset position of the tilting frame 501;

[0120] Step S902: Release the locking state of the flipping drive 504 so that the flipping frame 501 flips to a horizontal state by gravity;

[0121] Step S903: After the tipping frame 501 is flipped to a horizontal position, control the tipping plate 502 to be flipped to a horizontal position so as to transfer the fully loaded garbage bin 1 to the transfer vehicle.

[0122] Specifically, to prevent the tilting frame 501 from being subjected to both upward supporting force (from the first and second support columns) and downward pulling force from the tilting drive 504, which could lead to bending deformation and other damage, the tilting frame 501 needs to be tilted to a horizontal state from a second preset angle under the action of gravity. The tilting drive 504 is locked when performing the extension or retraction function. Opening the balance valve in the tilting drive 504 can release the tilting drive 504, and the retraction length of the tilting drive 504 can adaptively change as the tilting frame 501 tilts down. The above operation protects both the tilting frame 501 and the tilting drive 504.

[0123] In one embodiment of the present invention, the support beam 503 and the swing arm mounting frame 601 are connected by a connecting rod. When the swing arm mounting frame 601 moves to the first preset position of the tilting frame 501, the support beam 503 is determined to be at the third preset position of the tilting frame 501. When the swing arm mounting frame 601 moves to the second preset position of the tilting frame 501, the support beam 503 is determined to be at the fourth preset position of the tilting frame 501. That is, by controlling the moving drive component 506, the movement control of the swing arm mounting frame 601 and the support beam 503 can be realized simultaneously, which simplifies the structure of the tilting device 5 and reduces the difficulty of control.

[0124] In one embodiment of the present invention, the waste compression station includes a first waste compression unit, a second waste compression unit, a press head moving track 13, and a press head 3 arranged in parallel. Each waste compression unit includes a frame and a hopper 4. The press head moving track 13 includes a first longitudinal track, a second longitudinal track 1302, and a transverse track 1301 that passes laterally through the press head parking space. The first longitudinal track and the second longitudinal track 1302 are arranged perpendicular to the transverse track 1301 and extend longitudinally to the top of the waste bin placement space 7 of the first waste compression unit and the waste bin placement space 7 of the second waste compression unit, respectively.

[0125] Specifically, when neither the first nor the second waste compression unit has a need for waste compression, the pressure head 3 remains in the pressure head parking space; when either the first or the second waste compression unit has a need for waste compression, the pressure head 3 moves from the pressure head parking space to the waste compression unit that needs to be compressed, and compresses the waste in the waste bin 1 in the waste bin placement space 7. Since the waste compression station only has two waste compression units, the time spent moving the compression head 3 from the compression head parking space to one of the compression units, or from one compression unit to another (if waste compression is completed in one compression unit and no further compression is needed in the other, the compression head 3 returns to the parking space), is relatively short. Furthermore, while one compression unit is compressing waste, the other can perform unloading or transfer operations. The two compression units take turns compressing, reducing the idle time of the compression head 3 and the waiting time of the compression units that are not compressing waste. This further improves the matching balance between the number of compression heads 3 and the number of compression units, while also increasing the utilization efficiency of the compression head 3, the first compression unit, and the second compression unit, which is also conducive to further improving the overall operating efficiency of the waste compression station.

[0126] In one embodiment of the present invention, the waste compression station further includes a first traveling component 201 and a second traveling component 202. The first traveling component 201 is movably disposed on the transverse track 1301. The pressing head moving track 13 further includes a third longitudinal track 1303 disposed below the first traveling component 201 and capable of connecting with the first longitudinal track or the second longitudinal track 1302. The second traveling component 202 is movably disposed on the third longitudinal track 1303 and can move from the third longitudinal track 1303 to the first longitudinal track or the second longitudinal track 1302. The pressing head 3 is disposed below the second traveling component 202.

[0127] Specifically, a hydraulic system and an electrical system are provided above the first traveling component 201. The first traveling component 201 and the second traveling component 202 are driven by the first hydraulic drive motor and the second hydraulic drive motor in the hydraulic system, respectively. The electrical system includes a controller and a berthing sensor set on the transverse track 1301. Both the first traveling component 201 and the second traveling component 202 include a moving frame and multiple moving wheels set on the moving frame. When the first walking component 201 moves along the transverse track 1301 to the transverse position of the garbage compression unit that needs to be compressed, driven by the first hydraulic drive motor, the corresponding parking sensor of the garbage compression unit will obtain the corresponding detection result and send the detection result to the controller. The controller then controls the first hydraulic drive motor to stop driving, and the first walking component 201 stops moving. At this time, the third longitudinal track 1303 below the first walking component 201 docks with the first longitudinal track or the second longitudinal track 1302, so that the second walking component 202 moves along the first longitudinal track or the second longitudinal track 1302 under the drive of the second hydraulic drive motor to the top of the garbage bin placement space 7. After the second walking component 202 moves into position, the pressure head 3 can compress the garbage in the garbage bin 1.

[0128] In one embodiment of the present invention, a first position switch and a second position switch are provided at intervals on both the first longitudinal track and the second longitudinal track 1302. The first position switch and the second position switch are respectively located at the first displacement compression position point and the second displacement compression position point of the pressure head 3. Specifically, the first position switch and the second position switch are both communicatively connected to the controller. When the second walking component 202 moves the pressure head 3 to the position of the first position switch (or the second position switch), it triggers the first position switch (or the second position switch). After the first position switch is triggered, it sends a corresponding signal to the controller. The controller first controls the second walking component 202 to stop moving, and then controls the pressure head 3 to perform the extension and retraction function to compress the garbage in the garbage bin 1. That is, the pressure head 3 can compress the garbage in the garbage bin 1 at the first displacement compression position point and the second displacement compression position point. Compared with the fixed-point compression method, the cross-sectional area of ​​the compaction area of ​​this displacement compression method is larger, which can increase the compaction density of the garbage and further improve the compression effect of the garbage.

[0129] In one embodiment of the present invention, the waste compression station further includes a movable frame 14 disposed below the third longitudinal track 1303. The movable frame 14 has a compression head receiving space 1401 for accommodating the compression head 3, and a slag receiving tray 16 is provided at the bottom of the movable frame 14. That is, the movable frame 14 can move along the third longitudinal track 1303 on the transverse track 1301. After the compression head 3 moves to the first longitudinal track or the second longitudinal track 1302 with the second traveling component 202, the movable frame 14 remains above the transfer platform 11. After the compression head 3 completes the waste compression function, the second traveling component 202 returns to the transverse track 1301, and the compression head 3 returns to the movable frame 14. Furthermore, when the pressure head 3 completes the garbage compression function, garbage debris may stick to the bottom of the pressure head 3. The garbage debris may fall to the ground as the pressure head 3 moves. In this embodiment, the setting of the slag receiving tray 16 can make the garbage debris fall into the slag receiving tray 16 instead of falling on the path of the lateral movement of the pressure head 3, which is conducive to keeping the garbage compression station clean and further improving the environmental protection performance of the garbage compression station.

[0130] In one embodiment of the present invention, such as Figure 6 As shown, the slag receiving tray 16 is provided with a plurality of openable and closable first cleaning covers 1601. Specifically, in this embodiment, there are four first cleaning covers 1601, which are arranged in a rectangular array on the slag receiving tray 16. Each first cleaning cover 1601 can be opened individually to facilitate cleaning of the garbage debris in the slag receiving tray 16. In addition, the arrangement of multiple first cleaning covers 1601 helps to reduce the height space required when a single first cleaning cover 1601 is flipped down to open, and can also avoid the situation of localized stress concentration on the moving frame 14 and the slag receiving tray 16.

[0131] In one embodiment of the present invention, the mobile frame 14 is further provided with a first protective side plate, a second protective side plate, and a third protective side plate. The first protective side plate is on the side of the mobile frame 14 away from the unloading platform 12. The second and third protective side plates are respectively on the left and right sides of the first protective side plate. That is, no protective side plate is provided on the side of the mobile frame 14 facing the unloading platform 12, which facilitates the second walking assembly 202 to move the pressure head 3 into or out of the mobile frame 14. In addition, the provision of the first, second, and third protective side plates allows the pressure head 3 to be hidden inside the mobile frame 14, which improves the aesthetics of the waste compression station and also protects the pressure head 3 from external damage, thus helping to extend the service life of the pressure head 3.

[0132] In one embodiment of the present invention, the first protective side plate is provided with a plurality of openable and closable second cleaning covers 1602, such as Figure 5 As shown, in this embodiment, the cleaning personnel can apply outward force to flip and open the second cleaning cover 1602. There are two second cleaning covers 1602. The arrangement of the two second cleaning covers 1602 makes it convenient for the cleaning personnel to clean the garbage debris on the slag tray 16 except for the multiple first cleaning covers 1601.

[0133] In one embodiment of the present invention, the flipping device 5 is provided with a safety lock 15 for preventing the trash can 1 from falling to the ground. The safety lock 15 includes a mounting base 1501, a connector 1502, a locking plate assembly 1503, and a top rod 1504. The mounting base 1501 is disposed on the flipping frame 501 and forms a first groove 1505. The connector 1502 is disposed in the first groove 1505. The locking plate assembly 1503 is disposed in the first groove 1505 and rotatably connected to the connector 1502. The locking plate assembly 1503 can prevent the trash can 1, which is detached from the lifting mechanism 6, from falling to the ground when it is in the unfolded state. The top rod 1504 is used to drive the locking plate assembly 1503 to switch between the retracted state and the unfolded state through the connector 1502.

[0134] Specifically, the locking plate assembly 1503 includes a connecting portion 1509 and a support plate portion 1510 fixed together with the connecting portion 1509. The connecting member 1502 and the connecting portion 1509 are rotatably connected. The connecting portion 1509 and the support plate portion 1510 have a coincident pivot center. A support surface is formed on the support plate portion 1510. When the garbage bin 1 is hung on the tipping device 5 and is in a vertical state, the top rod 1504 of the safety lock 15 installed on the tipping device 5 is not under force, the locking plate assembly 1503 is in the unfolded state (at this time, the safety lock 15 is in the working state), and part of the support plate portion 1510 is located below the top block at intervals. The vertical interval between the support plate portion 1510 and the top block is 20mm-80mm, and the support surface faces the bottom wall of the top block. During unloading, as the amount of garbage in garbage bin 1 increases, the weight of garbage bin 1 also increases. If the hanging rod of garbage bin 1 accidentally detaches from the hook of the tipping device 5, garbage bin 1 will fall under the influence of gravity. However, in this embodiment, the safety lock 15 ensures that after garbage bin 1 falls, the top block of garbage bin 1 will land on the lock plate assembly 1503. The support surface on the lock plate assembly 1503 can support the top block of garbage bin 1, thereby preventing garbage bin 1 from falling further. When the tipping device 5 moves garbage bin 1 from a vertical position... When the displacement reaches the horizontal state, the top rod 1504 will be subjected to force and drive the connecting piece 1502 to move. The connecting piece 1502 then drives the locking plate assembly 1503 to pivot around its pivot center, thereby causing the locking plate assembly 1503 to gradually change from the unfolded state to the retracted state, so as to avoid the locking plate assembly 1503 affecting the transfer of the garbage bin 1. Furthermore, when the locking plate assembly 1503 is in the retracted state (at this time, the safety lock 15 is in the non-working state), the support plate part 1510 will be retracted into the first groove 1505.

[0135] In one embodiment of the present invention, such as Figure 12-14 As shown, a groove-shaped portion 1506 and a rod-shaped portion 1507 extending in the same direction are formed on the mounting base 1501. A first groove 1505 is formed on the groove-shaped portion 1506. A portion of the rod-shaped portion 1507 extends into the first groove 1505. One end of the push rod 1504 passes through the axial through hole of the rod-shaped portion 1507 and is rotatably connected to the end of the connector 1502 away from the locking plate assembly 1503. Specifically, the first end of the push rod 1504 passes through the axial through hole of the rod-shaped part 1507 and extends into the first groove 1505. The push rod 1504 can move axially along the axial through hole. One end of the connector 1502 is rotatably connected to the locking plate assembly 1503, and the other end of the connector 1502 is rotatably connected to the first end of the push rod 1504. When the second end of the push rod 1504 is subjected to a pushing or pulling force, it can drive the connector 1502 to move, thereby driving the locking plate assembly 1503 to pivot around its pivot center, so that the locking plate assembly 1503 can switch between the unfolded state and the retracted state.

[0136] In one embodiment of the present invention, the safety lock 15 further includes a sliding groove 1512 disposed in the first groove 1505, a second groove 1513 formed on the sliding groove 1512, a first sliding groove 1514 and a second sliding groove 1515 respectively formed on the two side walls of the second groove 1513, a portion of the push rod 1504 extends into the second groove 1513 and is rotatably connected to the connector 1502 through a rotating shaft 1516, and the two ends of the connector 1502 can move along the first sliding groove 1514 and the second sliding groove 1515 respectively. Specifically, the slide 1512 is disposed on one side of the rod-shaped portion 1507. The first slide 1514 and the second slide 1515 are disposed along the axial direction of the slide 1512. One end of the rotating shaft 1516 is engaged on the outer side wall of the first slide 1514, and the other end of the slide passes through the first slide 1514, the push rod 1504, the connector 1502 and the second slide 1515 and is engaged on the outer side wall of the second slide 1515. When the push rod 1504 moves along the axial through hole, the rotating shaft 1516 also moves along the length direction of the first slide 1514 and the second slide 1515. The arrangement of the slide 1512 guides the movement of the push rod 1504 and also prevents the connector 1502 and the locking plate assembly 1503 from deviating from their vertical plane when they move.

[0137] In another embodiment of the invention, such as Figure 15-17As shown, the mounting base 1501 has a groove-shaped portion 1506 and a rod-shaped portion 1507 extending perpendicularly to each other. The safety lock 15 also includes a sliding groove member 1512 disposed in the first groove 1505. A sliding groove is formed on the sliding groove member 1512. One end of the top rod 1504 passes through the axial through hole of the rod-shaped portion 1507 and the bottom wall of the first groove 1505 in sequence and is connected to the sliding groove member 1512. The first end of the connector 1502 is rotatably connected to the lock plate assembly 1503. The second end of the connector 1502 is rotatably connected to the groove-shaped portion 1506. The third end of the connector 1502 is rotatably connected to a sliding member movably disposed in the sliding groove. Specifically, in this embodiment, the sliding member is a rotating shaft 1516, the setting direction of the groove-shaped portion 1506 and the setting direction of the rod-shaped portion 1507 are perpendicular to each other, the connecting member 1502 includes a first connecting rod portion and a second connecting rod portion, the first end of the first connecting rod portion is rotatably connected to the locking plate assembly 1503, the second end of the first connecting rod portion is rotatably connected to the first end of the second connecting rod portion through the rotating shaft 1516 (i.e., the sliding member), the second end of the second connecting rod portion is rotatably connected to the groove-shaped portion 1506, a second groove 1513 is formed on the sliding groove member 1512, a first sliding groove 1514 and a second sliding groove 1515 are formed on the two side walls of the second groove 1513 respectively, one end of the rotating shaft 1516 is engaged on the outer side wall of the first sliding groove 1514, and the other end of the sliding groove passes through the first sliding groove 1514, the first connecting rod portion, the second connecting rod portion and the second sliding groove 1515 and is engaged on the outer side wall of the second sliding groove 1515. When the top rod 1504 moves along the axial through hole, the sliding member moves relative to the bottom wall of the first groove 1505, the rotating shaft 1516 moves along the length direction of the first slide groove 1514 and the second slide groove 1515, and the first connecting rod and the second connecting rod also make adaptive movements to drive the locking plate assembly 1503 to pivot around its pivot center, thereby allowing the locking plate assembly 1503 to switch between the unfolded state and the retracted state.

[0138] In one embodiment of the present invention, the safety lock 15 further includes a stop plate 1517 and a spring 1518. The stop plate 1517 is disposed at the end of the push rod 1504 away from the groove portion 1506. The end of the rod portion 1507 away from the groove portion 1506 forms an annular inner cavity 1508. The spring 1518 is sleeved on the outer periphery of the push rod 1504 and located between the side end faces of the stop plate 1517 and the annular inner cavity 1508. Specifically, the outer diameter of the stop plate 1517 is larger than the outer diameter of the rod portion 1507 to limit the movement distance of the push rod 1504 when it moves toward the locking plate assembly 1503. The spring 1518 is sleeved on the outer periphery of the push rod 1504, with one end of the spring 1518 abutting against the side end face of the annular cavity and the other end of the spring 1518 abutting against the side end face of the stop plate 1517. When the push rod 1504 is not under pressure (i.e., at the locking plate assembly 1503), In the unfolded state, spring 1518 is in an extended state; when the push rod 1504 is under pressure, spring 1518 is compressed, and the locking plate assembly 1503 retracts towards the direction of the first groove 1505; when the locking plate assembly 1503 of the safety lock 15 needs to switch from the retracted state to the unfolded state, the push rod 1504 is no longer under pressure and moves away from the locking plate assembly 1503 under the action of the spring force of spring 1518, thereby driving the locking plate assembly 1503 to unfold. In another embodiment of the present invention, a stepped portion may also be provided at one end of the push rod 1504 near the anti-shift plate 1517. In this case, one end of spring 1518 abuts against the side end face of the annular cavity, and the other end of spring 1518 abuts against the side end face of the stepped portion.

[0139] In another embodiment of the present invention, the safety lock 15 further includes a pivot shaft 1520 and a torsion spring 1519 disposed on the groove portion 1506. The lock plate assembly 1503 is rotatably sleeved on the pivot shaft 1520, and the torsion spring 1519 is sleeved on the rotating cylinder portion 1511 of the lock plate assembly 1503. One end of the torsion spring 1519 is connected to the connecting portion 1509 of the lock plate assembly 1503, and the other end of the torsion spring 1519 is connected to the groove portion 1506. Specifically, the connecting part 1509, the support plate part 1510, and the rotating cylinder part 1511 are fixed together (or the connecting part 1509, the support plate part 1510, and the rotating cylinder part 1511 are integrally formed). The locking plate assembly 1503 as a whole can pivot around the pivot axis 1520. When the push rod 1504 is not under pressure (i.e., when the locking plate assembly 1503 is in the unfolded state), the torsion spring 1519 is in the natural state. When the push rod 1504 is under pressure, the torsion spring 1519 is twisted and is in a torsional state, and the locking plate assembly 1503 retracts in the direction of the first groove 1505. When the locking plate assembly 1503 of the safety lock 15 needs to switch from the retracted state to the unfolded state, the push rod 1504 is no longer under pressure, the torsion spring 1519 returns to the natural state and drives the locking plate assembly 1503 to unfold, while the push rod 1504 moves away from the locking plate assembly 1503. In another embodiment of the present invention, the safety lock 15 may be provided with both a spring 1518 and a torsion spring 1519. The arrangement of the spring 1518 and the torsion spring 1519 is the same as in the above embodiment, so as to further ensure the reliability of the safety lock 15 during use.

[0140] In one embodiment of the present invention, the safety lock 15 further includes an adjusting disc assembly 1521 for adjusting the torque of the torsion spring 1519. The adjusting disc assembly 1521 includes an adjusting bolt, an adjusting nut, and an adjusting disc 1522 sleeved on the pivot shaft 1520. A first circular hole is provided on the groove-shaped portion 1506, and a plurality of second circular holes 1523 are provided on the adjusting disc 1522, evenly distributed circumferentially. One end of the adjusting bolt abuts against the outer wall of the groove-shaped portion 1506, and the other end of the adjusting bolt passes sequentially through the first circular hole and the second circular holes 1523, forming a threaded connection with the adjusting nut. The end of the torsion spring 1519 away from the connecting portion 1509 is connected to the adjusting disc 1522. When it is necessary to adjust the torque of the torsion spring 1519 to ensure the support reliability of the lock plate assembly 1503, the adjusting bolt and adjusting nut can be disassembled, and the second circular holes 1523 on the adjusting disc 1522 aligned with the first circular hole can be changed according to actual needs. Then, the adjusting bolt and adjusting nut can be reinstalled.

[0141] In one embodiment of the present invention, the flipping device 5 further includes a top wheel 17 for driving the safety lock 15 to switch from a working state to a non-working state. Specifically, in embodiments where the orientation of the groove 1506 and the rod 1507 are the same, the top wheel 17 is mounted on the fixed frame 505 and is located on the top of the side of the fixed frame 505 facing the garbage bin placement space 7. In embodiments where the orientation of the groove 1506 and the rod 1507 are perpendicular to each other, the top wheel 17 is mounted independently of the flipping device 5. Regardless of the position of the top wheel 17, as the flipping frame 501 gradually flips from a vertical state to a horizontal state, the top rod 1504 of the safety lock 15 will gradually come into contact with the top wheel 17 and be subjected to pressure applied by the top wheel 17. After being subjected to pressure, the top rod 1504 will transmit the pressure to the connecting member 1502 and drive the connecting member 1502 to move. The connecting member 1502 will then drive the locking plate assembly 1503 to pivot around its pivot center, thereby causing the locking plate assembly 1503 to gradually change from an unfolded state to a retracted state, so as to avoid the locking plate assembly 1503 affecting the transfer of the garbage bin 1.

[0142] In one embodiment of the present invention, a baffle portion 403 is formed on the top of the hopper 4. The baffle portion 403 includes a plurality of baffle side plates 404, which are inclined plates or vertical plates. Specifically, as shown in the figure... Figure 18 As shown, the hopper 4 includes a feeding section 401, a discharging section 402, and a baffle section 403. The discharging section 402 is connected to the bottom of the feeding section 401, and the baffle section 403 is located above the feeding section 401, forming a discharge channel 406 together with the feeding section 401 and the discharging section 402. The baffle side plate 404 is an inclined plate or a vertical plate, which can make the top area of ​​the baffle section 403 smaller, reducing the probability of garbage debris falling onto the top of the baffle section 403 during garbage dumping, and thus reducing the probability of garbage debris falling outside the hopper 4 during the upward tilting of the hopper 4. In addition, even if garbage debris falls onto the top of the baffle section 403, it can easily slide down the inclined or vertical inner wall of the baffle section 403 under the action of gravity and enter the discharge channel 406, which is conducive to improving the environmental performance and reliability of the garbage compression station.

[0143] In one embodiment of the present invention, the enclosure portion 403 protrudes from the unloading platform 12 and has an avoidance gap 405 on the side near the unloading platform 12. This arrangement can reduce the height difference between the garbage bin and the hopper 4 of the unloading vehicle, improve the convenience of garbage directly entering the unloading channel 406 when dumping garbage, and further reduce the possibility of garbage spilling outward.

[0144] In one embodiment of the present invention, the hopper 4 further includes a sealing portion 18 disposed on the side of the enclosure portion 403 away from the clearance notch 405 and for close contact with the sealing strip 1001 at the bottom of the roller shutter door 10. The sealing portion 18 is labyrinthine and forms a debris collection space 19 with an opening tilted downwards. Specifically, as Figure 22 As shown, the sealing part 18 is bent multiple times to form a maze structure, in which a debris collection space 19 is formed. The above arrangement can not only apply a downward obstruction force to the sealing strip 1001, increasing the difficulty for the roller shutter door 10 and the sealing strip 1001 to move away from the unloading channel 406, but also increase the difficulty for garbage or odor to overflow during unloading. Even if some garbage debris enters the debris collection space 19 of the sealing part 18 due to excessive airflow, when the roller shutter door 10 rises, the garbage debris in the debris collection space 19 can fall back into the unloading channel 406 and then into the garbage bin 1.

[0145] In one embodiment of the present invention, such as Figure 19-21 As shown, the waste compression station also includes a bollard 20 located on the side of the unloading platform 12 near the clearance opening 405, and the hopper 4 also includes a cover plate 21 located on the side of the feeding section 401 near the clearance opening 405 and capable of covering the top of the bollard 20. Specifically, the bollard 20 effectively prevents the unloading vehicle from colliding with the hopper 4, thus protecting the hopper 4; when the hopper 4 is in operation, the cover plate 21 rests on the top surface of the bollard 20, preventing a gap between the hopper 4 and the bollard 20, thereby preventing waste debris from falling into the gap and entering the waste container 1's holding space.

[0146] In one embodiment of the present invention, the stop block 20 is provided with a first inclined surface 2001 and a second inclined surface 2002 from top to bottom on the side near the unloading platform 12. The inclination angle λ of the second inclined surface 2002 is greater than the inclination angle β of the first inclined surface, and the vertical height of the second inclined surface 2002 is greater than the vertical height of the first inclined surface 2001. Specifically, the first inclined surface 2001 is connected to the top surface of the stop block 20 (the top surface of the stop block 20 is a horizontal surface), and the second inclined surface 2002 is connected to the bottom surface of the stop block 20 (the bottom surface of the stop block 20 is a horizontal surface). When the hopper 4 is in the working state, the cover plate 21 is placed on the top surface of the stop block 20 and part of the first inclined surface 2001. The above arrangement can effectively prevent the unloading vehicle from accidentally colliding with the cover plate 21 when reversing, thus protecting the cover plate 21.

[0147] In one embodiment of the present invention, a garbage cleaning channel 22 for connecting the unloading platform 12 and the unloading channel 406 is formed on the stop 20 and the cover plate 21. If garbage accidentally falls onto the unloading platform 12 during unloading, the staff can sweep the garbage on the unloading platform 12 into the unloading channel 406 through the garbage cleaning channel 22, which improves the convenience of cleaning the garbage on the unloading platform 12.

[0148] In one embodiment of the present invention, such as Figure 23 As shown, a sealing ring 23 is provided on the top wall of the garbage bin 1. The sealing ring 23 is arranged in a ring shape. The hopper 4 also includes a sealing plate 24 that surrounds the outer peripheral wall of the discharge section 402 and can press against the top of the sealing ring 23. Specifically, the inlet of the garbage bin 1 is larger than the outlet of the hopper 4. When the garbage bin 1 and the hopper 4 are in working condition, the hopper 4 is located above the garbage bin 1. There may be a gap between the garbage bin 1 and the hopper 4 in the circumferential direction. When garbage falls into the garbage bin 1, it may overflow outward through the gap. In this embodiment, the sealing ring 23 and the sealing strip 1001 are provided to seal the gap, enhance the tightness of the connection between the garbage bin 1 and the hopper 4, and prevent garbage from overflowing between the two. Furthermore, the sealing ring 23 and the sealing plate 24 are both made of elastic rubber, so that the sealing ring 23 and the sealing plate 24 can deform adaptively with force, further enhancing the reliability and effectiveness of the seal between the garbage bin 1 and the hopper 4.

[0149] In one embodiment of the present invention, both the first and second waste compression units further include rubber plate assemblies that are inclinedly disposed on the frame 9 and used to make close contact with the left and right sides of the enclosure 403. Specifically, the left and right sides of the frame 9 are respectively provided with a first rubber plate mounting seat and a second rubber plate mounting seat. The first and second rubber plate mounting seats are located inside the partitions on the left and right sides of the first and second waste compression units, respectively. The rubber plate assembly includes a first rubber plate for inclined installation on the first rubber plate mounting seat and a second rubber plate for inclined installation on the second rubber plate mounting seat. When the hopper 4 is tilted downward into place, the left and right sides of the enclosure 403 will contact the first and second rubber plates and apply pressure to them. The first and second rubber plates will adaptably deform to fit more tightly with the left and right sides of the enclosure 403, thereby enhancing the connection tightness between the hopper 4 and the frame 9 or the partition and preventing waste debris from spilling out from the left and right sides of the enclosure 403 during unloading.
