Abstract

This invention discloses a pusher mechanism, a garbage compactor, and a garbage compression method. The pusher mechanism includes a pusher capable of lateral pushing motion. The pusher has a fixed pushing part and a movable pushing part. The fixed pushing part has a receiving cavity with an opening at its bottom. The movable pushing part is movably mounted on the fixed pushing part. During its stroke, the movable pushing part can move from the opening to at least partially concealed within the receiving cavity, allowing only the fixed pushing part to perform the pushing motion. The movable pushing part can also move to at least partially outside the receiving cavity from the opening and below the fixed pushing part, allowing both the fixed and movable pushing parts to perform the pushing motion together. In this invention, by changing the pusher area, a clearance space is created at the rear of the garbage transfer container, allowing uncompacted garbage to fall without affecting the gate's closure, thereby improving the garbage entrainment problem at the rear of the garbage transfer container.

Description

Technical Field

[0001] This invention relates to the field of waste compression technology, and in particular to a pusher mechanism, a waste compressor, and a waste compression method. Background Technology

[0002] The problem of waste getting stuck in the gate has always been an inherent pain point in horizontal waste compression processes. This is because the process requires a small door, also known as a gate, to be installed at the back of the container. When waste needs to be compressed into the container, the gate is raised, and when the container is full, the gate is lowered. However, during the process of the gate falling after the container is full, the compressed waste in front of the container will rebound or roll down under the influence of gravity. When the waste rolls down to the bottom of the gate, it gets stuck between the gate and the container when the gate falls.

[0003] The problem of garbage being carried away not only increases the workload of transfer station operators, but also leads to penalties from management departments for the operating units due to garbage spillage and sewage leakage during transit.

[0004] The existing technology for solving the problem of waste trapping in gates employs a switching gate technology. This switching gate can be combined with a waste compressor pusher to form a composite pusher. After an empty waste transfer container is connected to the waste compressor, the compressor pusher initially extends when empty (without waste), engaging with the switching gate at the rear of the container to form the composite pusher. This composite pusher then compresses the waste into the container. Once the container is full, the pusher disengages from the switching gate, remaining at the rear of the container. However, this method involves modifying the existing waste transfer container, resulting in significant operational costs. Summary of the Invention

[0005] The main objective of this invention is to provide a pusher mechanism, a waste compressor, and a waste compression method, which aims to solve the problem of waste entrainment at the gate of a waste transfer container.

[0006] To achieve the above objectives, the present invention proposes a pusher mechanism for a garbage compactor. The pusher mechanism includes a pusher capable of lateral pushing motion. The pusher has a fixed pushing portion and a movable pushing portion. The fixed pushing portion has a receiving cavity with an opening at its bottom. The movable pushing portion is movably mounted on the fixed pushing portion. During the stroke of the movable pushing portion:

[0007] The movable pushing part can move from the opening to be at least partially concealed within the receiving cavity, so that only the fixed pushing part performs the pushing activity;

[0008] The movable pushing part can also be moved to be at least partially outside the receiving cavity from the opening and located below the fixed pushing part, so that the fixed pushing part and the movable pushing part can perform pushing activities together.

[0009] Optionally, when the movable pushing part is at least partially concealed within the receiving cavity, the movable pushing part closes the opening, and the pushing surface of the movable pushing part is flush with the lower end surface of the fixed pushing part.

[0010] Optionally, the movable pushing part is rotatably mounted on the fixed pushing part.

[0011] Optionally, the movable pushing part includes a fan-shaped pushing body, the fan-shaped pushing body having a large end and a small end, the small end being hinged to the fixed pushing part;

[0012] The pusher mechanism further includes a first linear drive device, which has a first loading part with a first linear travel stroke, and the first loading part drives the side end connected to the fan-shaped pusher body.

[0013] Optionally, the first linear drive device includes a hydraulic cylinder, the hydraulic cylinder includes a cylinder barrel and a push rod, the first loading part includes the push rod, the cylinder barrel and the inner wall of the receiving cavity of the fixed pressing part are hinged, the push rod and the side end of the fan-shaped pressing body are hinged, and the hydraulic cylinder is used to drive the fan-shaped pressing body to move from the opening to at least partially concealed in the receiving cavity.

[0014] Optionally, the pusher mechanism further includes a second linear drive device, the second linear drive device having a second loading part with a second linear travel, the second loading part being driven to connect to the fixed pusher.

[0015] Optionally, the pusher mechanism further includes a scraping structure, the scraping structure comprising:

[0016] The scraper body is arranged around the opening, and the scraper body abuts against the movable pushing part.

[0017] The present invention also proposes a garbage compressor for connection to a garbage transfer container, comprising:

[0018] A pusher mechanism includes a pusher capable of pushing laterally. The pusher has a fixed pushing part and a movable pushing part. The fixed pushing part has a receiving cavity with an opening at its bottom. The movable pushing part is movably mounted on the fixed pushing part. During the stroke of the movable pushing part:

[0019] The movable pushing part can move from the opening to be at least partially concealed within the receiving cavity, so that only the fixed pushing part performs the pushing activity;

[0020] The movable pushing part can also be moved to at least partially outside the receiving cavity from the opening and located below the fixed pushing part, so that the fixed pushing part and the movable pushing part can perform a pushing action together; and,

[0021] The compressor body has a cavity with multiple opening channels, one of which is used to communicate with the waste transfer container. The pusher mechanism is movably disposed in the cavity along the lateral direction.

[0022] The present invention also proposes a waste compression method, which is applied to the above-mentioned waste compressor. The waste compressor is used to connect with a waste transfer container. The waste transfer container includes a gate. The pusher mechanism further includes a first linear drive device and a second linear drive device. The pusher has an initial avoidance position, a material pushing and compression position, and a compaction position in its active stroke.

[0023] The waste compression method includes the following steps:

[0024] After the garbage transfer container is docked with the garbage compressor and a start command is received, the second linear drive device is controlled to extend and retract, so that the pusher head moves back and forth between the initial avoidance position and the material pushing and compression position.

[0025] When the waste transfer container is fully loaded, and when the fixed pressing part moves to the material compression position, the first linear drive device is controlled to extend, so that the movable pressing part extends out of the receiving cavity from the opening.

[0026] The second linear drive device is controlled to extend and retract again, so that the pusher head reciprocates between the pushing compression position and the compaction position;

[0027] After the number of motions counted meets the preset number, the second linear drive device is controlled to retract, so that the pusher head returns to the material compression position, and the first linear drive device is controlled to retract, so that the movable pushing part is partially hidden in the receiving cavity.

[0028] The second linear drive device is controlled to retract again, so that the pusher head moves from the material compression position to the initial avoidance position.

[0029] Optionally, before the step of controlling the first linear drive device to extend so that the movable pushing part extends out of the receiving cavity from the opening, the method further includes:

[0030] Obtain the current weight of the waste transfer container; when the current weight of the waste transfer container exceeds a preset weight, determine that the waste transfer container is fully loaded; and / or,

[0031] The current pressure value of the pusher head of the garbage compressor is obtained. When the current pressure value of the pusher head exceeds the preset pressure value, the garbage transfer box is determined to be in a full-load state.

[0032] In the technical solution of this invention, the pusher in the pusher mechanism can reciprocate laterally to push and solidify the waste into the waste transfer container. The pusher includes a fixed pushing part and a movable pushing part. The fixed pushing part has a receiving cavity, and the movable pushing part is movably installed within the receiving cavity. When the fixed pushing part moves to push the waste into the waste transfer container, the movable pushing part acts as a buffer, partially concealed within the receiving cavity from the opening, thus not affecting the pushing effect of the fixed pushing part. When the waste transfer container is full of waste, the pusher then pushes and solidifies the waste. The waste inside the transfer container solidifies. At this point, the movable pushing part extends from the opening of the receiving cavity and is located below the fixed pushing part. The movable pushing part and the fixed pushing part combine to form a pusher with a variable cross-sectional area, which pushes and solidifies the waste at the bottom of the rear of the waste transfer container, forming a clearance space with the stroke length of the movable pushing part. On the one hand, after the waste is squeezed and compacted, it will not immediately expand and fall, thus preventing the gate from trapping it. On the other hand, because of the clearance space, even if the waste above rebounds or rolls down, it will only fall into the clearance space and not directly below the gate, ultimately avoiding the problem of waste trapping the gate of the waste transfer container. In addition, the technical solution of this invention does not involve the modification of existing waste transfer vehicles, so the improvement cost is small and easier to implement in practical applications.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0046] The problem of waste getting stuck in the gate has always been an inherent pain point in horizontal waste compression processes. This is because the process requires a small door, also known as a gate, to be installed at the back of the container. When waste needs to be compressed into the container, the gate is raised, and when the container is full, the gate is lowered. However, during the process of the gate falling after the container is full, the compressed waste in front of the container will rebound or roll down under the influence of gravity. When the waste rolls down to the bottom of the gate, it gets stuck between the gate and the container when the gate falls.

[0047] The problem of garbage being carried away not only increases the workload of transfer station operators, but also leads to penalties from management departments for the operating units due to garbage spillage and sewage leakage during transit.

[0048] The existing technology for solving the problem of waste trapping in gates involves "switching gate" technology. The switching gate can be combined with the garbage compactor pusher to form a composite pusher. After the empty garbage transfer container is connected to the garbage compactor, the compactor pusher initially extends when empty (without garbage) and connects with the switching gate at the rear of the container to form the composite pusher. The composite pusher then compresses the garbage into the container. Once the container is full, the pusher disconnects from the switching gate and remains at the rear of the container. However, this method involves modifying the existing garbage transfer container, resulting in significant operational costs.

[0049] To address the aforementioned problems, the main objective of this invention is to provide a pusher mechanism, a waste compressor, and a waste compression method, aiming to provide a pusher mechanism, a waste compressor, and a waste compression method that can solve the problem of waste entrainment at the gate of a waste transfer container. Figures 1 to 2 This is a schematic diagram of one embodiment of the pusher mechanism in this invention. Figures 3 to 6 This is a schematic diagram of one embodiment of the garbage compressor provided in this invention.

[0050] Please refer to Figures 1 to 2 This invention proposes a pusher mechanism 100 for a garbage compactor 1000. The pusher mechanism 100 includes a pusher 1 capable of lateral pushing motion. The pusher 1 has a fixed pushing part 11 and a movable pushing part 12. The fixed pushing part 11 has a receiving cavity with an opening at its bottom. The movable pushing part 12 is movably mounted on the fixed pushing part 11. During its travel, the movable pushing part 12 can move from the opening to at least partially concealed within the receiving cavity, allowing only the fixed pushing part 11 to perform the pushing motion. The movable pushing part 12 can also move to at least partially outside the receiving cavity from the opening and below the fixed pushing part 11, allowing both the fixed pushing part 11 and the movable pushing part 12 to perform the pushing motion together.

[0051] It is understood that in the technical solution of the present invention, the pusher 1 in the pusher mechanism 100 can reciprocate laterally to push and solidify the garbage into the garbage transfer container. Since the pusher 1 includes a fixed pushing part 11 and a movable pushing part 12, the fixed pushing part 11 has a receiving cavity, and the movable pushing part 12 can be movably installed within the receiving cavity. When the fixed pushing part 11 moves to push the garbage into the garbage transfer container, the movable pushing part 12 has an avoidance effect, partially concealed within the receiving cavity from the opening of the receiving cavity, thus not affecting the pushing effect of the fixed pushing part 11. When the garbage in the garbage transfer container is sufficient, the pusher 1 is then used to... The waste inside the waste transfer container is pushed and solidified. At this time, the movable pushing part 12 extends from the opening of the receiving cavity and is located below the fixed pushing part 11. The movable pushing part 12 and the fixed pushing part 11 combine to form a pusher head 1 with a variable cross-sectional area, which pushes and solidifies the waste at the bottom of the tail of the waste transfer container, and forms a clearance space with the stroke length of the movable pushing part 12. On the one hand, after the waste is squeezed and compacted, it will not immediately expand and fall, thus preventing the gate from trapping it. On the other hand, because a clearance space is formed, even if the waste above rebounds or rolls down, it will only fall into the clearance space and will not fall directly below the gate, ultimately avoiding the problem of waste trapping the gate of the waste transfer container. In addition, the technical solution of the present invention does not involve the modification of existing waste transfer vehicles, so the improvement cost is small and easier to implement in practical applications.

[0052] Furthermore, when the pusher 1 is used to push the garbage in the garbage compressor 1000 to the garbage transfer box, the pusher 1 exerts a squeezing and pushing action. The lower end face of the fixed pushing part 11 is fitted with the bottom surface of the garbage compressor 1000, while the movable pushing part 12 is located at least partially hidden in the receiving cavity. The movable pushing part 12 closes the opening to prevent garbage from getting stuck in the receiving cavity under the reciprocating motion of the pusher 1, thus hindering the movement of the movable pushing part 12. Moreover, the pushing surface of the movable pushing part 12 is flush with the lower end face of the fixed pushing part 11, which can further prevent the garbage that has not been pushed from being carried back when the pusher reciprocates.

[0053] In addition, please refer to Figure 1 and Figure 2The movable pushing part 12 is rotatably mounted on the fixed pushing part 11. In some other embodiments, the movable pushing part 12 can be mounted on the fixed pushing part 11 via a slide rail, and can change the cross-section of the push head 1 by moving it up and down, which can to a certain extent push out the avoidance space. In the embodiment of this application, the effect of the movable pushing part 12 and the fixed pushing part 11 being rotatably connected is that when the movable pushing part 12 rotates from the opening, it can push and sweep the garbage that was originally concentrated below the interactive pushing part, pushing it into the depth of the garbage transfer box, rather than simply pressing down on the garbage. This avoids simply pressing down on the garbage and then causing the subsequent garbage to rebound and shrink the avoidance space. Therefore, the setting of this embodiment can better maintain the avoidance space to accommodate the garbage and avoid the phenomenon of being trapped to a greater extent.

[0054] In some embodiments, the movable pushing part 12 includes a fan-shaped pushing body with a large end and a small end. The small end is hinged to the fixed pushing part 11. The large end is an arc surface. When the movable pushing part 12 is outside the receiving cavity, the large end is used to contact the bottom surface of the waste transfer box. The side end of the fan-shaped pushing body is used to push and apply pressure. The arc surface of the large end can avoid interference with other components during rotation, allowing the movable pushing part 12 to rotate smoothly. In addition, the pushing head mechanism 100 also includes a first linear drive device 2. The first linear drive device 2 has a first loading part with a first linear stroke. The first loading part drives the side end connected to the fan-shaped pushing body. The first loading part can drive the fan-shaped pushing body to reciprocate between the opening and the lower side of the fixed pushing part 11 to realize operations such as pushing and compacting waste.

[0055] It is understood that the first linear drive device 2 includes a hydraulic cylinder. In other embodiments of the present invention, the first linear drive device 2 also includes a cylinder, a hydraulic motor, and a linkage mechanism, etc., which can be used to drive the movable pushing part 12. This application does not impose any limitations here. In this embodiment, the hydraulic cylinder includes a cylinder barrel and a push rod. The first loading part includes the push rod. The cylinder barrel and the inner wall of the receiving cavity of the fixed pushing part 11 are hinged. The push rod and the side end of the fan-shaped pushing body are hinged. The hydraulic cylinder drives the fan-shaped pushing body to reciprocate from the lower end of the fixed pushing part 11 to at least partially concealed in the receiving cavity through the telescopic push rod. In this embodiment, the purpose of using a hydraulic cylinder is that hydraulic transmission can output a large thrust or a large torque, which can realize low-speed, high-tonnage movement. Applied to this application, it can achieve a large thrust in the process of pushing and solidifying waste, resulting in a better solidification and pushing effect on the waste, and avoiding the rebound of the movable pushing part 12.

[0056] In addition, please refer to Figure 4 The pusher mechanism 100 further includes a second linear drive device 3. The second linear drive device 3 has a second loading part with a second linear stroke, and the second loading part drives and connects to the fixed pushing part 11. The second linear drive device 3 can be used to push the pusher 1 in a lateral reciprocating motion, which can realize both the transfer of waste and the solidification and compression of waste. The linear drive device includes a hydraulic cylinder, a pneumatic cylinder, a motor, or a linkage mechanism. This application does not impose any restrictions, as long as it can achieve the telescopic pushing effect.

[0057] Please refer to Figure 2 To further prevent waste from being carried back into the waste compressor 1000 during the reciprocating motion of the pusher head 1, the pusher head mechanism 100 also includes a scraping structure 4. The scraping structure 4 includes a scraper plate body 41, which surrounds the opening and is used to contact the movable pushing part 12, preventing the movable pushing part 12 from carrying waste into the opening during its reciprocating motion, making it difficult to clean. It is understood that in embodiments of the present invention, when the movable pushing part 12 is configured as a fan-shaped pushing body, the large end face and two fan-shaped side faces of the fan-shaped pushing body can contact the scraper plate body 41. When the fan-shaped pushing body rotates, the waste on the large end face and two fan-shaped side faces can be scraped by the scraper plate body 41, preventing the fan-shaped pushing body from carrying waste into the cavity. Specifically, the scraper body 41 includes an iron plate, a special nylon slider, and a bolt connection structure for fixing the special nylon slider. The iron plate forms the frame structure of the scraper body 41 and fixes the special nylon slider. The special nylon slider abuts against the movable pushing part 12 and increases the friction between it and the movable pushing part 12, thereby better preventing garbage from adhering. The bolt connection structure connects the iron plate and the special nylon slider.

[0058] The present invention also proposes a garbage compressor 1000 for connection with a garbage transfer container, including the pusher mechanism 100. The garbage compressor 1000 adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] In addition, please refer to Figures 3 to 6The garbage compressor 1000 also includes a compressor body 200, which has a cavity. The cavity has multiple opening channels, one of which is used to communicate with the garbage transfer box. The pusher mechanism 100 is movably disposed in the cavity. More specifically, the pusher mechanism 100 moves along one end of the opening channel to the other end of the opening channel and extends out of the opening channel to solidify and push the garbage. The other opening channel of the cavity is located at the upper end, which is used to allow the garbage to fall into the cavity from top to bottom. The pusher mechanism 100 then pushes the garbage that falls into the cavity into the garbage transfer box.

[0060] The present invention also proposes a garbage compression method, which is applied to the garbage compressor 1000 described above. It is understood that the garbage compression method adopts all the technical solutions of all the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0061] In addition, the garbage compressor 1000 is used to connect with the garbage transfer container, the garbage transfer container includes a gate, the pusher mechanism 100 also includes a first linear drive device 2 and a second linear drive device 3, and the pusher 1 has an initial avoidance position, a material pushing and compression position and a compaction position in its active stroke.

[0062] The waste compression method includes the following steps:

[0063] After the garbage transfer container is docked with the garbage compressor 1000 and a start command is received, the second linear drive device 3 is controlled to extend and retract, so that the pusher 1 moves back and forth between the initial avoidance position and the material pushing and compression position.

[0064] When the garbage transfer container is fully loaded, and when the fixed pressing part 11 moves to the material compression position, the first linear drive device 2 is controlled to extend, so that the movable pressing part 12 extends out of the receiving cavity from the opening.

[0065] The second linear drive device 3 is controlled to extend and retract again, so that the pusher head 1 reciprocates between the material pushing and compression position and the compaction position;

[0066] After the number of motions counted meets the preset number, the second linear drive device 3 is controlled to retract so that the pusher head 1 returns to the material compression position, and the first linear drive device 2 is controlled to retract so that the movable pushing part 12 is partially hidden in the receiving cavity.

[0067] The second linear drive device 3 is controlled to retract again, so that the pusher head 1 moves from the material compression position to the initial avoidance position.

[0068] It is understood that the initial avoidance position refers to the position of the pusher head 1 located in the cavity of the garbage compressor 1000 away from the garbage transfer box, the material pushing and compression position refers to the position where the pusher head 1 extends a certain distance out of the garbage compressor 1000, and the compaction position is the position that is deeper into the garbage compressor 1000 than the material pushing and compression position.

[0069] Therefore, in the above steps, when the pusher 1 is in the initial avoidance position, for the garbage compressor 1000, this is the garbage accumulation step, and the garbage needs to be transported from the opening channel into the cavity. For the garbage transfer box, it is necessary to unload the box first, remove the empty garbage transfer box from the garbage truck, and connect the garbage transfer box and the garbage compressor 1000, and then open the gate. After the waste transfer container is docked with the waste compressor 1000, a start command is obtained, controlling the second linear drive device 3 to drive the pusher head 1. The pusher head 1 reciprocates between the initial avoidance position and the material compression position, pushing the waste into the waste transfer container until the waste transfer container is full. At this time, when the fixed pushing part 11 moves to the material compression position, the first linear drive device 2 is controlled to extend, driving the movable pushing part 12 to extend out of the receiving cavity from the opening, thereby increasing the cross-sectional area of ​​the pusher head 1 and enabling it to contact and abut against the bottom of the waste transfer container to achieve a better pushing effect. Then, the second linear drive device 3 is controlled to extend... The pusher head 1 reciprocates between the material pushing and compression position and the compaction position, applying strong pressure to the waste several times. This compacts and solidifies the waste near the gate, creating a clearance space during the pushing process, allowing the waste to bounce and fall without landing directly below the gate. Once the number of compressions reaches a preset number (this application does not limit this, as long as compression and solidification are achieved), the second linear drive device 3 is then controlled to retract, returning the pusher head 1 to the material pushing and compression position. The first linear drive device 2 is then controlled to retract, partially concealing the movable pushing part 12 within the receiving cavity. This retraction of the movable pushing part 12 allows the pusher head 1 to return to its initial clearance position, thus completing the compression effect.

[0070] In addition, it is necessary to control the gate to descend, separate the garbage transfer container and the garbage compressor 1000, and then transfer the garbage transfer container by moving it with a hook-lift truck to finally realize the compression process, thus avoiding the phenomenon of gate jamming.

[0071] Furthermore, prior to the step of controlling the first linear drive device 2 to extend so that the movable pushing part 12 extends out of the receiving cavity from the opening, the method further includes:

[0072] Obtain the current weight of the waste transfer container; when the current weight of the waste transfer container exceeds a preset weight, determine that the waste transfer container is fully loaded; and / or,

[0073] The current pressure value of the pusher head 1 of the garbage compressor 1000 is obtained. When the current pressure value of the pusher head 1 exceeds the preset pressure value, the garbage transfer box is determined to be in a full-load state.

[0074] On the one hand, by measuring the weight of the waste transfer container, the full load status of the container can be determined, preventing underloading that wastes transport capacity and overloading that hinders the compression effect. On the other hand, a pressure sensor can be installed on the pusher head 1 to measure the pressure it experiences. When the pressure reaches a preset value, it indicates that the resistance from the waste has reached a certain limit. Further pushing will only increase the resistance, indicating that there is insufficient space in the waste transfer container to hold more waste.

[0075] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the present invention specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.

A garbage compressor for connection to a garbage transfer container, characterized in that, include: The pusher mechanism as described in any one of claims 1 to 7; as well as, The compressor body (200) has a cavity with multiple opening channels, one of which is used to communicate with the garbage transfer container. The pusher mechanism is movably disposed in the cavity along the lateral direction.

9. A waste compression method, applied in a waste compressor as described in claim 8, wherein the waste compressor is connected to a waste transfer container, the waste transfer container including a gate, characterized in that, The pusher mechanism further includes a first linear drive device (2) and a second linear drive device (3). The pusher (1) has an initial avoidance position, a material pushing and compression position and a compaction position on its active stroke. The waste compression method includes the following steps: After the garbage transfer container is docked with the garbage compressor and a start command is received, the second linear drive device (3) is controlled to extend and retract so that the pusher (1) moves back and forth between the initial avoidance position and the material pushing and compression position. When the garbage transfer box is fully loaded, and when the fixed pressing part (11) moves to the material compression position, the first linear drive device (2) is controlled to extend, so that the movable pressing part (12) extends out of the receiving cavity from the opening; Control the extension and retraction of the second linear drive device (3) again so that the pusher (1) reciprocates between the material pushing and compression position and the compaction position; After the number of motions counted meets the preset number, the second linear drive device (3) is controlled to retract so that the pusher (1) returns to the material compression position, and the first linear drive device (2) is controlled to retract so that the movable pushing part (12) is partially hidden in the receiving cavity. The second linear drive device (3) is controlled to retract again, so that the pusher (1) moves from the material compression position to the initial avoidance position.

10. The waste compression method as described in claim 9, characterized in that, Before the step of controlling the first linear drive device (2) to extend so that the movable push part (12) extends out of the receiving cavity from the opening, the method further includes: Obtain the current weight of the waste transfer container; when the current weight of the waste transfer container exceeds a preset weight, determine that the waste transfer container is fully loaded; and / or, The current pressure value of the pusher (1) of the garbage compressor is obtained. When the current pressure value of the pusher (1) exceeds the preset pressure value, the garbage transfer box is determined to be in a full-load state.
