Description

Technical Field

[0001] This utility model relates to the field of waste compression and packaging equipment, specifically to a multi-station plastic compression and packaging equipment and a waste compression station equipped with the equipment. Background Technology

[0002] After kitchen waste is screened, some organic matter is separated and used for anaerobic fermentation to produce biogas, while the inorganic matter (mostly plastic) is screened and then transported for processing. When processing the screened inorganic plastics, due to their large volume and light weight, they need to be compressed and packed. Currently, the main method for transporting plastic waste is to install a horizontal compressor at the inlet of the waste transport container. The compressor moves horizontally within the container, compressing the waste. However, this compression method occupies some container space, preventing the container from being fully filled. Furthermore, this unidirectional compression method results in insufficient compaction and wasted space. Additionally, after compression, the waste is mainly transported using a baler and flatbed trucks. This method has the following problems: firstly, it requires consumables such as baling wire during operation; secondly, it requires dedicated personnel to use forklifts for transport, stacking, and loading after baling, consuming manpower and resources, resulting in high operating costs. Secondly, the sorted impurities contain moisture, which can cause some wastewater to overflow during packaging and transportation, resulting in secondary pollution. Furthermore, the odor is difficult to control centrally, leading to significant odor pollution within the factory. Thirdly, unpacking the stacked packages requires cumbersome procedures.

[0003] To avoid this problem, Chinese Patent Application No. 2024107701222 discloses a vertical split-type two-way garbage compactor, including a frame. The lower end of the frame has a mounting structure for mounting on one side of the garbage bin's garbage disposal opening. A horizontal compressor is mounted on the frame, and a vertical movement control mechanism for the compressor is located between the horizontal compressor and the frame. This mechanism drives the horizontal compressor downwards and extends into the garbage bin from the garbage disposal opening. A pressure head is located on the upper outer side of the horizontal compressor on the frame, and a vertical movement control mechanism for the pressure head is located between the pressure head and the frame. In application, this garbage compactor can only compress at a fixed position. When the garbage bin is full, it needs to be stopped, the current garbage bin moved, and another garbage bin transported to the compressor before it can be restarted for compression. This results in low compression efficiency. Furthermore, the existing pusher cannot crush or shear the garbage during compression, leading to incomplete compression. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a multi-station plastic compression and packing equipment and a garbage compression station with the equipment, so as to solve the problems that the existing garbage compression device can only compress at the current station, and can only compress again after the machine is stopped and the garbage is transferred to another garbage box. The compression efficiency is low, and the garbage cannot be sheared during the compression process, resulting in incomplete compression.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A multi-station plastic compression and packing device includes a frame and a waste compression mechanism mounted on the frame. The waste compression mechanism includes a feeding hopper located above the waste bin inlet, with both ends of the feeding hopper being open. A pusher is installed at the lower end of the feeding hopper, and the pusher can reciprocate horizontally under the drive of a telescopic mechanism. Two transverse guide rails are spaced apart in the middle of the frame and can be raised and lowered along the height of the frame for positioning. At least two compression stations are located below the transverse guide rails. The feeding hopper is located at one of the compression stations, and its upper end is suspended between the two transverse guide rails, allowing it to reciprocate along the height of the frame with the transverse guide rails. This allows the pusher to longitudinally compress the waste in the waste bin or move it downwards to a set height, placing it in the waste bin and positioning it. A transverse drive mechanism connected to the feeding hopper is installed on the transverse guide rails, allowing the feeding hopper to move and position itself along the length of the transverse guide rails under the drive of the transverse drive mechanism, thus moving from the current compression station to the next compression station. The front end of the pusher is serrated.

[0006] With the aforementioned compression device, when compressing the waste in the garbage bin, the transverse guide rail is first controlled to move downwards until the feed hopper enters the bin and is positioned. Then, the inorganic plastic waste is transported to the top of the feed hopper via an external conveyor belt and enters the garbage bin. After the waste enters, the telescopic mechanism is activated to drive the pusher head to move back and forth, compressing the inorganic plastic waste during this reciprocating motion. During the compression process, the serrated front end of the pusher head shears the inorganic plastic during compression, making it easier and more thorough. Simultaneously, inorganic plastics have a smoother surface compared to other waste during compression, allowing them to be continuously pushed and flow within the bin after compression. Therefore, even with the pusher head positioned only at the top of the garbage bin, the bin can be filled during compression. After the garbage bin is compacted, the transverse guide rail is controlled to move up and down, causing the pusher head to move up and down as well. The lower end of the pusher head then longitudinally compresses the waste at the feed inlet, achieving bidirectional compression of the waste. After the current station's compression is completed, simply activate the transverse drive mechanism. The transverse drive mechanism will then move the feed hopper along the transverse guide rail, allowing it to move to the next station and align with the waste bin at another station. This setup eliminates the need to wait for the compressed waste bin to be transferred, enabling the hopper to reach the next station without stopping the machine. This multi-station operation effectively improves work efficiency.

[0007] Furthermore, the frame includes a left upright and a right upright, and a telescopic hydraulic cylinder and a slider are provided on both the left and right uprights. The telescopic hydraulic cylinder is vertically arranged, and its lower end is mounted on the left or right upright via a hinge seat. The piston rod end of the telescopic hydraulic cylinder is hinged to the slider. The transverse guide rail is fixedly installed between the two sliders.

[0008] The left and right uprights, along with the transverse guide rail, form a stable mechanism. The transverse guide rail is connected to the left and right uprights via sliders, which are supported by the piston rod of a telescopic hydraulic cylinder. With this structure, when the piston rod of the telescopic hydraulic cylinder extends or retracts, it drives the two sliders to move up and down along the left and right uprights and to their positions, thus raising and lowering the transverse guide rail. The overall operation is smooth, and the structure is compact.

[0009] Furthermore, the left and right uprights are symmetrically arranged, with their lower ends fixed to the ground by fasteners, forming multiple compression stations between the left and right uprights; each of the left and right uprights includes two rectangular tubes and multiple crossbeams connected between the two rectangular tubes; a through hole for the piston rod to pass through is provided on the crossbeam located in the middle, and the hinge seat is installed in the middle of the lower crossbeam, with the telescopic hydraulic cylinder passing through the through hole in the middle and connecting to the lower end of the slider.

[0010] The left and right uprights are symmetrically arranged for easy layout. The rectangular tubes and crossbeams on the left and right uprights, when connected, form a stable frame structure, providing a stable mounting structure for the telescopic hydraulic cylinder and hinged seat. The through hole on the middle crossbeam allows the piston rod to pass through and guides it, ensuring stable piston rod operation.

[0011] Furthermore, a horizontally arranged support plate is fixedly installed on both the left and right sides of the upper end of the feed hopper, with the two ends of the support plate respectively placed inside the corresponding transverse guide rail; multiple bearing seats are provided on both support plates, and a rotating shaft is sleeved inside the support seat, with a guide roller clamped on the transverse guide rail at both ends of each rotating shaft; the transverse drive mechanism is connected to one of the rotating shafts, including a drive motor and a reducer, with the input end of the reducer connected to the drive motor and the output end fixedly connected to the corresponding rotating shaft.

[0012] With the above structure, when it is necessary to move the feed hopper to the next compression station, the drive motor can be started. After the drive motor is turned on, it drives the gear in the connected tachometer to rotate, which in turn drives the shaft connected to the reducer to rotate. After the shaft rotates, the guide rollers at both ends of the shaft can rotate and move along the length of the transverse guide rail during rotation, thus moving the feed hopper. In this structure, the guide rollers on the two shafts are rectangularly distributed, forming four-point support, which makes the sliding more stable. The feed hopper is mounted and suspended on the transverse guide rail by a support plate, which is convenient for installation. At the same time, the support plate also provides support and installation space for the support base and the shaft.

[0013] Furthermore, the feed hopper includes a left side plate, a right side plate, a front baffle, and a rear guide plate arranged vertically. The front baffle and the rear guide plate are both fixed between the left side plate and the right side plate, and the upper end of the rear guide plate is inclined. The longitudinal height of the front baffle is less than the height of the left side plate and the right side plate. Multiple blocks are spaced apart at the lower end of the front baffle, and the side of the blocks facing the inclined guide plate is inclined.

[0014] The feed hopper is mainly composed of four connected plates, forming a feeding space in the middle. The rear guide plate corresponds to the end of the conveyor belt that transports waste. After the waste enters, it first falls downwards along the inclined surface of the rear guide plate before entering the waste bin. This way, the waste is not directly fed in, but guided by the inclined surface before falling vertically, slowing down the initial descent speed. Simultaneously, the lower end of the inclined surface corresponds to the installation position of the pusher extension mechanism, providing sufficient installation space for the mechanism. The front baffle is the direction for the pusher to extend forward. Setting the height of the front baffle lower than the left and right side plates avoids interference between the front baffle and the pusher during forward movement, allowing for proper pusher movement. Multiple stops on the front baffle prevent waste from being carried back to the feed inlet when the pusher returns to its original position.

[0015] Furthermore, two guide pillars are provided on the inner sides of the left and right side plates and below the front baffle, with the two guide pillars forming a push head guide groove; the telescopic mechanism includes two cross-arranged push cylinders, the front end of which is rotatably connected to the rear end of the push head, and the rear end is rotatably installed on the inner side of the left or right side plate.

[0016] After the telescopic cylinder is activated, it drives the cylinder rod to extend and retract, while the pusher head moves back and forth along the guide groove, providing guidance for the pusher head and making its extension and retraction more stable. The telescopic mechanism consists of two pusher cylinders, which are arranged in a cross pattern, making the installation space more compact. Furthermore, the pusher head moves more smoothly during the reciprocating motion of the two pusher cylinders during extension and retraction.

[0017] A waste compression station with a multi-station plastic compression and packing device includes the multi-station plastic compression and packing device as described above. At each compression station, a waste bin is placed. The inlets of each waste bin are on the same side, and the inlet of one of the waste bins corresponds to the feed hopper of the waste compression mechanism. A discharge gate is provided on the side of each waste bin away from the inlet, and a sewage pipe connected to an external sewage treatment pipeline is provided near the discharge gate.

[0018] With multiple garbage bins arranged side-by-side in the garbage compression station, each bin corresponds to a compression station, enabling multi-station compression and avoiding efficiency reduction caused by downtime after the garbage in one bin has been compressed. When compressing inorganic plastics, because the inorganic plastic waste still contains a certain amount of moisture after the initial screening, the compressed wastewater flows to the bottom of the garbage bin and is eventually discharged through the sewage pipe, making the interior of the compressed waste drier.

[0019] Furthermore, each compression station is equipped with a ground rail for the garbage bins to slide on, and the ground rail extends in front of and behind the compression station. Multiple garbage bins are arranged in rows on the ground rail. Each garbage bin is equipped with at least two casters at its lower end, and the casters are placed inside the ground rail.

[0020] The trash cans can be placed in rows or columns. When moving them, the locking mechanism of the casters is released, the hooks are engaged with the hooks on the trash cans, and the trash cans are pulled along the rails. This method allows for rapid transfer of trash cans. After compression is completed at the front of the current column of trash cans, the next trash can is moved while the previous trash can is being compressed. During this process, the trash can that has been compressed at the previous station is pulled out, and the empty trash cans in the same column are pushed to the compression station. This achieves rapid trash can repositioning, making the operation quick and convenient.

[0021] Furthermore, each garbage bin has a cover plate at its inlet to seal the inlet. One side of the cover plate is rotatably connected to the garbage bin body, and a hydraulic cylinder rod is located at the lower end of the cover plate, with its end rotatably connected to it. This design allows the cover plate to rotate by extending and retracting the hydraulic cylinder rod, thereby opening or closing the cover plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. The waste compression mechanism can move up and down reciprocally under the drive of the lifting mechanism to achieve longitudinal compression of waste. At the same time, the waste compression mechanism has a built-in pusher that can move horizontally reciprocally under the drive of the telescopic mechanism to achieve horizontal compression of waste. This dual compression method can compress waste more thoroughly. The waste being compressed is inorganic plastic waste, which has a relatively smooth surface and can flow during the compression process. Placing the pusher at the top of the waste bin before compression effectively increases the compression space.

[0023] 2. The garbage compression mechanism can also move along the transverse guide rail in the frame, from one compression station to another, and between multiple compression stations to meet the needs of multi-station compression. This avoids the time wasted by stopping the machine to transfer garbage bins after single-station compression, and can effectively improve compression efficiency.

[0024] 3. The garbage compression station is equipped with multiple rows of garbage bins and sliding rails for easy transport of the bins. Simultaneously, wastewater pipes inside each bin drain the wastewater squeezed out during compression, keeping the inside of the bins dry. Attached Figure Description

[0028] Example 1 Kitchen waste mainly consists of organic matter and inorganic plastics. After screening the kitchen waste, the inorganic plastics need to be compressed and then packed for recycling. However, existing garbage compactors can only compress at a fixed station. When garbage bin 7 is full, the machine needs to be stopped, the current garbage bin 7 needs to be moved, and then another garbage bin 7 needs to be transported to the compressor before it can be started again for compression. This results in low compression efficiency. At the same time, the existing pusher 3 cannot crush or shear the garbage during the compression process, resulting in incomplete compression.

[0029] like Figures 1-4 As shown, this embodiment provides a multi-station plastic compression and packing equipment, including a frame 1 and a waste compression mechanism mounted on the frame 1. The waste compression mechanism includes a feeding hopper 2 located above the inlet of the waste bin 7. The feeding hopper 2 is open at both its upper and lower ends. A pusher 3 is installed at the lower end of the feeding hopper 2. The pusher 3 can reciprocate horizontally under the drive of a telescopic mechanism 4. Two transverse guide rails 14 are spaced apart in the middle of the frame 1 and can be raised and lowered and positioned along the height of the frame 1. Two compression stations are provided below the transverse guide rails 14 (in specific implementations, more than two stations can be set). The feeding hopper 2 is located at one of the compression stations, and the upper end of the feeding hopper 2 is suspended from the two transverse guide rails 14. Between the guide rails 14, the pusher head 3 can reciprocate with the transverse guide rails 14 in the height direction of the frame 1, driving the pusher head 3 to longitudinally squeeze the garbage in the garbage bin 7 or move it downward to a set height (the set height is the height from the initial height of the feed hopper 2 to the top of the garbage bin 7, where the pusher head 3 is placed in the garbage bin 7), and then place it in the garbage bin 7 and position it; a transverse drive mechanism 5 connected to the feed hopper 2 is installed on the transverse guide rails 14, and the feed hopper 2 can move and be positioned along the length direction of the transverse guide rails 14 under the drive of the transverse drive mechanism 5, so as to move from the current compression station to the next compression station; the extension path of the pusher head 3 is perpendicular to the transverse guide rails 14, and the front end of the pusher head 3 is serrated.

[0030] When using the compression device in this embodiment, to compress the waste in the garbage bin 7, the transverse guide rail 14 is first controlled to move downwards until the feed hopper 2 enters the garbage bin 7 and is positioned. Then, the inorganic plastic waste is transported to the upper end of the feed hopper 2 via an external conveyor belt and enters the garbage bin 7 through the feed hopper 2. After the waste enters, the telescopic mechanism 4 is activated to drive the pusher head 3 to move back and forth. During the reciprocating movement, the inorganic plastic waste is squeezed. During the squeezing process, because the front end of the pusher head 3 is serrated with multiple sharp corners, it can shear the inorganic plastic while squeezing it, making it easier and more thorough to squeeze. At the same time, the inorganic plastic has a smoother surface than other waste during the squeezing process, and can be continuously pushed and flow in the bin after squeezing. Thus, even though the pusher head 3 is only located at the upper end of the garbage bin 7, it can still fill the garbage bin 7 during the squeezing process. After the garbage bin 7 is compressed and compacted, the horizontal guide rail 14 is controlled to move up and down, thereby driving the pusher head 3 to move up and down as well. The lower end of the pusher head 3 longitudinally compresses the garbage at the feed inlet, thus achieving bidirectional compression of the garbage. After the compression at the current station is completed, the horizontal drive mechanism 5 is activated. The horizontal drive mechanism 5 drives the feed hopper 2 to move along the horizontal guide rail 14, and then it can move to the next station, so that the feed hopper 2 corresponds to the garbage bin 7 at another station. This setting does not require waiting for the compressed garbage bin 7 to be transferred. It can reach the next station without stopping the machine, realizing multi-station operation and effectively improving work efficiency.

[0031] like Figure 1 , Figure 2 As shown, the frame 1 includes a left upright and a right upright. A telescopic hydraulic cylinder 6 and a slider 13 are mounted on both the left and right uprights. The telescopic hydraulic cylinder 6 is vertically positioned, with its lower end mounted on the left or right upright via a hinged seat. The piston rod of the telescopic hydraulic cylinder 6 is hinged to the slider 13. The transverse guide rail 14 is fixedly installed between the two sliders 13. Specifically, in this embodiment, the slider 13 is hollow in the middle, and a vertical through hole is provided on both the left and right sides of the slider 13 to cooperate with the left or right upright. Because the slider 13 is hollow in the middle, it is lighter, thereby reducing the overall weight of the transverse guide rail 14 and the feed hopper 2. In this embodiment, the transverse guide rail 14 is made of I-beams and is welded to the slider 13 or detachably connected via connectors.

[0032] The left and right uprights, along with the transverse guide rail 14, form a stable mechanism. The transverse guide rail 14 is connected to the left and right uprights via sliders 13, which are supported by the piston rod of the telescopic hydraulic cylinder 6. With this structure, when the piston rod of the telescopic hydraulic cylinder 6 extends or retracts, it drives the two sliders 13 to move up and down along the left and right uprights and to their positions, thus raising and lowering the transverse guide rail 14. The overall operation is smooth, and the structure is compact.

[0033] Furthermore, the left and right uprights are symmetrically arranged, with their lower ends fixed to the ground by fasteners, forming multiple compression stations between the left and right uprights; each of the left and right uprights includes two rectangular tubes 11 and three crossbeams 12 connected between the two rectangular tubes 11; a through hole is provided on the crossbeam 12 located in the middle for the piston rod of the telescopic hydraulic cylinder 6 to pass through, and the hinge seat is installed in the middle of the lower crossbeam 12, after the telescopic hydraulic cylinder 6 passes through the through hole in the middle, it is connected to the lower end of the slider 13.

[0034] The left and right uprights are symmetrically arranged for easy layout. The rectangular tubes 11 and crossbeams 12 on the left and right uprights are connected to form a stable frame structure, providing a stable mounting structure for the telescopic hydraulic cylinder 6 and the hinge seat. The through holes on the middle crossbeam 12 allow the piston rod to pass through and guide it, ensuring stable piston rod operation.

[0035] like Figure 2 As shown, a horizontally arranged support plate 26 is fixedly installed on both the left and right sides of the upper end of the feed hopper 2. The two ends of the support plate 26 are respectively placed inside the corresponding transverse guide rail 14. Multiple bearing seats are provided on both support plates 26, and a rotating shaft 53 is sleeved inside the support seat. Each rotating shaft 53 has a guide roller 54 at both ends that is locked on the transverse guide rail 14. The transverse drive mechanism 5 is connected to one of the rotating shafts 53 and includes a drive motor 51 and a reducer 52. The input end of the reducer 52 is connected to the drive motor 51, and the output end is fixedly connected to the corresponding rotating shaft 53. To protect the bearing seats and the rotating shaft 53, a protective cover is also installed on the two support plates 26 to cover the rotating shaft 53 and the bearing seats. In this embodiment, the rotating shaft 53 is sleeved on the output gear of the reducer 52 and is keyed to the output gear. The reducer 52 is located outside the transverse guide rail 14.

[0036] With the above structure, when it is necessary to move the feed hopper 2 to the next compression station, the drive motor 51 can be started. After the drive motor 51 is started, it drives the gear in the tachometer connected to it to rotate, and finally drives the rotating shaft 53 connected to the reducer 52 to rotate. After the rotating shaft 53 rotates, the guide rollers 54 at both ends of the rotating shaft 53 can rotate and move along the length of the transverse guide rail 14 during the rotation, thus moving the feed hopper 2. In this structure, the guide rollers 54 on the two rotating shafts 53 are rectangularly distributed, forming four-point support, which makes the sliding more stable. The feed hopper 2 is installed and suspended on the transverse guide rail 14 by the support plate 26, which is convenient for installation. At the same time, the support plate 26 can also provide support and installation space for the support base and the rotating shaft 53.

[0037] like Figure 3As shown, the feed hopper 2 includes a left side plate 21, a right side plate 22, a front baffle 23, and a rear guide plate 25 arranged vertically. The front baffle 23 and the rear guide plate 25 are both fixed between the left side plate 21 and the right side plate 22. The upper end of the rear guide plate 25 is inclined. The longitudinal height of the front baffle 23 is less than the height of the left side plate 21 and the right side plate 22. Multiple blocks 24 are spaced apart at the lower end of the front baffle 23. The side of the block 24 facing the inclined guide plate is inclined.

[0038] The feed hopper 2 is mainly composed of four connected plates, forming a feeding space in the middle. The rear guide plate 25 corresponds to the end of the conveyor belt that transports waste. After the waste enters, it first falls downwards along the inclined surface of the rear guide plate 25 before entering the waste bin 7. This way, the waste is not directly fed in, but guided by the inclined surface before falling vertically, slowing down the initial descent speed. Simultaneously, the lower end of the inclined surface corresponds to the installation position of the pusher head 3 telescopic mechanism 4, providing sufficient installation space for the telescopic mechanism 4. The front baffle 23 is the direction for the pusher head 3 to extend forward. By setting the height of the front baffle 23 to be less than that of the left side plate 21 and the right side plate 22, interference between the front baffle 23 and the pusher head 3 can be avoided when the pusher head 3 moves forward, allowing for proper movement. Multiple stops 24 on the front baffle 23 can block the waste when the pusher head 3 returns to its original position, preventing the waste from being carried back to the feed inlet.

[0039] Furthermore, two guide posts 211 are provided on the inner side of the left side plate 21 and the right side plate 22, and below the front baffle 23, with the two guide posts 211 forming a push head guide groove; the telescopic mechanism 4 includes two cross-arranged push cylinders, the front end of which is rotatably connected to the rear end of the push head 3, and the rear end is rotatably installed on the inner side of the left side plate 21 or the right side plate 22.

[0040] After the telescopic cylinder is activated, during the extension and retraction of the cylinder rod, the pusher 3 reciprocates along the guide groove, providing guidance for the pusher 3 and making its extension and retraction more stable. The telescopic mechanism 4 consists of two push cylinders, which are arranged in a cross pattern, making the installation space more compact. Furthermore, when the two push cylinders extend and retract, the pusher 3 moves more smoothly during reciprocating motion.

[0041] Example 2 like Figure 4As shown, this embodiment provides a waste compression station with a multi-station plastic compression and packing equipment, including the multi-station plastic compression and packing equipment as described above. A waste bin 7 is placed at each compression station, and the inlet 71 of each waste bin 7 is on the same side. The inlet of one of the waste bins 7 corresponds to the feed hopper 2 of the waste compression mechanism. A discharge door 72 is provided on the side of each waste bin 7 away from the inlet. A sewage pipe (not shown in the figure) connected to an external sewage treatment pipeline is provided near the discharge door 72. A hook is provided on the outer wall of the waste bin on the side corresponding to the discharge door 72 (when it is necessary to pull the waste bin, the hook can be engaged with the hook on the walking equipment, and the waste bin 7 can be moved by the walking equipment).

[0042] After multiple garbage bins 7 are arranged side by side in the garbage compression station, each garbage bin 7 corresponds to one compression station, which can meet the needs of multi-station compression and avoid the efficiency reduction caused by downtime when the garbage in one garbage bin 7 is completed. When compressing inorganic plastics, since the inorganic plastic waste still contains a certain amount of moisture after the initial screening, the wastewater generated after compression will flow to the bottom of the garbage bin 7 and eventually be discharged through the sewage pipe, making the inside of the compressed garbage drier.

[0043] like Figure 5 As shown, each compression station is provided with a ground rail 8 for the garbage bin 7 to slide on. The ground rail 8 extends in front of and behind the compression station, and multiple garbage bins 7 are arranged in rows on the ground rail 8. Each garbage bin 7 is provided with four rectangular casters 73 at its lower end, and the casters 73 are placed inside the ground rail 8.

[0044] The trash cans 7 are arranged in rows with two compression stations. Each compression station has one row of trash cans 7, allowing them to be placed in rows and columns. During transport, the locking mechanism of the casters 73 is released, the hooks are engaged with the hooks on the trash cans 7, and the trash cans 7 are pulled along the rails. This method allows for rapid transfer of the trash cans 7. After compression is completed at the front of the current row of trash cans 7, the trash cans 7 that have been compressed at the previous station are pulled out, and the empty trash cans 7 in the same row are pushed to the compression station. This achieves rapid repositioning of the trash cans 7, making the operation quick and convenient.

[0045] Each garbage bin 7 has a cover plate at its inlet to seal the inlet. One side of the cover plate is rotatably connected to the garbage bin body, and a hydraulic cylinder rod is located at the lower end of the cover plate, with its end rotatably connected to the cylinder rod. This arrangement allows the cover plate to rotate by extending or retracting the hydraulic cylinder rod, thereby opening or closing the cover plate.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
