Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a waste feeding machine with a double-layer pusher. Background Technology

[0002] The garbage pusher is a key piece of equipment in the garbage compression and transfer system. It is mainly used to push garbage from the unloading and collection point to subsequent processing equipment such as garbage compressors. It is widely used in various garbage transfer stations and treatment plants.

[0003] Currently, most common garbage pusher loader systems on the market are single-layer pusher structures. For small or medium-sized garbage storage silos, this type of equipment can meet basic usage requirements. However, when facing large silos requiring dual unloading stations or large storage volumes, existing technologies typically adopt a simple approach of enlarging the size of the individual equipment to meet loading capacity requirements. This involves significantly lengthening and heightening the single pusher and its associated hopper. The size (length and height) and weight of the single pusher increase dramatically with the increase in silo size, leading to a corresponding increase in the stroke and specifications of its drive cylinder. This not only increases the cost of equipment materials and manufacturing but also results in an excessively large installation area, placing excessive demands on site space. Furthermore, excessively deepening the hopper to increase storage volume exacerbates the density of garbage accumulation within the silo. In deeper silos, garbage particles are prone to compression and friction, forming a stable "arch" structure, or "bridging" phenomenon. This prevents garbage from falling smoothly into the pusher's action area, causing blockage at the unloading port and severely affecting the continuous and stable operation of the garbage transfer station.

[0004] Existing patent document CN200720138301.6 discloses a "double-push-head trolley feeding device", which adopts a scheme of arranging double push heads on both sides of the material discharge port. However, this structure does not change the singleness of the feeding plane and is complex. It has limited effectiveness in solving the problems of material blockage in large deep silos and the large size of equipment. For example, patent document CN201711217266.1 discloses a "compound pusher device", which adds a baffle to a single pusher to achieve secondary scraping. It is mainly used in garbage truck compartments. Its structure and working principle are fundamentally different from those of fixed large garbage loading machines and cannot solve the aforementioned fundamental problems.

[0005] Therefore, there is an urgent need in this field for a new type of waste feeding machine that can effectively overcome the technical defects of existing single-layer pusher feeders, such as large equipment size, high energy consumption, low efficiency and easy blockage, while ensuring a large storage capacity.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a garbage feeder with a double-layer pusher. By adopting a double-layer pusher structure with the main and auxiliary pushers working in coordination, the feeder's interior is divided into upper and lower pushing spaces, significantly shortening the stroke and size of a single pusher. This effectively reduces the overall size, weight, and manufacturing cost of the equipment while ensuring a large storage capacity, and also lowers the drive energy consumption of the hydraulic system. Its stepped feeding process greatly improves the pushing efficiency and continuity. At the same time, the reduced hopper depth, combined with the material level monitoring function, effectively prevents garbage blockage and "bridging" phenomena, ensuring stable and reliable operation.

[0025] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, a waste feeder with a double-layer pusher includes: a feeder body 1, a hopper 2, a main pusher assembly 8, a secondary pusher assembly 9, a main pusher shovel 6, and a secondary pusher shovel 7. The hopper 2 is disposed on the feeder body 1. The main pusher shovel 6 is slidably disposed on the bottom plate 103 inside the feeder body 1 via the main pusher assembly 8. A secondary pusher mounting plate 104 is horizontally disposed above the main pusher shovel 6. The secondary pusher mounting plate 104 divides the middle and rear space inside the feeder body 1 into upper and lower layers in the height direction. The secondary pusher shovel 7 is slidably disposed on the secondary pusher mounting plate 104 via the secondary pusher assembly 9. The main pusher assembly 8 and the secondary pusher assembly 9 can respectively control the main pusher shovel 6 and the secondary pusher shovel 7 to move back and forth towards the discharge port of the feeder body 1. A partition is horizontally disposed on the secondary pusher shovel 7. The partition can close the hollow area above the secondary pusher shovel 7 when the secondary pusher shovel 7 pushes material.

[0028] It should be noted that the feeding body 1, as the supporting and enclosing frame of the overall structure, provides a closed and stable working space for the storage, stratification, and pushing of waste; the hopper 2, located on the upper part of the body, serves as the initial receiving device for waste, and its inclined or vertical walls guide the material unloaded by the waste truck into the interior of the feeding body 1. The main pusher shovel 6, as the bottom pushing execution component, is driven by the main pusher assembly 8 (usually hydraulically driven) to slide back and forth against the surface of the bottom plate 103 inside the feeding body 1, thereby pushing the waste accumulated at the bottom layer forward; above the main pusher shovel 6, a secondary pusher mounting plate 104 is horizontally arranged, which rigidly divides the internal space of the body in the height direction, forming a clear upper and lower pushing channel; the secondary pusher shovel 7, as the upper pushing execution component, is driven by the independent secondary pusher assembly 9. Driven by the main pusher assembly 8, the main pusher shovel 6 and the auxiliary pusher shovel 7 reciprocate on the surface of the auxiliary pusher mounting plate 104, which is specifically responsible for pushing the garbage in the upper space. This allows the main pusher assembly 8 and the auxiliary pusher assembly 9 to control the main pusher shovel 6 and the auxiliary pusher shovel 7 to move back and forth in the direction of the discharge port of the upper material feeder body 1, realizing the decomposition and relay of the pushing operation. When the auxiliary pusher shovel 7 pushes the material in the direction of the discharge port, the baffle on the auxiliary pusher shovel 7 simultaneously closes the hollow area above the auxiliary pusher shovel 7, preventing garbage from scattering from the hollow area or falling into the rear of the pusher shovel, and ensuring the continuity and stability of the pushing process.

[0029] Furthermore, the feeding machine body 1 is enclosed by side plates 101 on all four sides, and one end of the upper part of the feeding machine body 1 is closed by the top plate 102 of the machine body, while the other end is provided with a hollow area; the hopper 2 is installed on the feeding machine body 1 by connecting with the hollow area of ​​the upper part of the feeding machine body 1; the lower part of the feeding machine body 1 is provided with a discharge port on one side corresponding to the garbage compressor 4, and a compression chamber docking hopper 105 is fixed at the discharge port. The compression chamber docking hopper 105 is sealed to the compression chamber of the garbage compressor 4 and has a trapezoidal structure with a cross-section that is narrow at the top and wide at the bottom.

[0030] It should be noted that the upper part of the feeding machine body 1 is enclosed by the top plate 102, which protects the pusher assembly in the rear area of ​​the machine body from external debris or internal garbage entering the pusher assembly. The hollow area at the other end provides an interface for the docking of the hopper 2 and the machine body, ensuring that the garbage received by the hopper 2 can smoothly enter the machine body. By docking with the upper hollow area, the hopper 2 can accurately guide the garbage unloaded by the garbage collection vehicle to the pusher operation area inside the machine body, avoiding garbage leakage during unloading. The discharge port at the lower part of the feeding machine body 1, corresponding to the garbage compressor 4, is the final outlet for the pusher to push the garbage, providing a channel for the garbage to be transported from the machine body to the compressor. The compression chamber docking hopper body 105 fixed at the discharge port is sealed to the compression chamber of the garbage compressor 4, which not only prevents the garbage from scattering from the docking part during the process of pushing to the compressor, but also guides the garbage to fall smoothly into the compression chamber through its own cross-sectional structure that is narrow at the top and wide at the bottom, ensuring a tight connection between the feeding and compression links and avoiding interruption of material transportation.

[0031] Furthermore, the main push assembly 8 includes a main push cylinder 81 and a main push mounting base 82. The main push mounting base 82 is fixed to the middle and rear part of the bottom plate 103 inside the feeding machine body 1. One end of the main push cylinder 81 is hinged to the side of the main push shovel 6 away from the discharge port, and the other end is hinged to the main push mounting base 82, and can drive the main push shovel 6 to slide axially along the bottom plate 103 of the feeding machine body 1. The auxiliary push assembly 9 includes an auxiliary push cylinder 91 and an auxiliary push mounting base 92. The auxiliary push mounting base 92 is fixed to the middle and rear part of the auxiliary push mounting plate 104. One end of the auxiliary push cylinder 91 is hinged to the side of the auxiliary push shovel 7 away from the discharge port, and the other end is hinged to the auxiliary push mounting base 92, and can drive the auxiliary push shovel 7 to slide axially along the auxiliary push mounting plate 104.

[0032] It should be noted that the main push mounting base 82 provides a stable mounting reference for the pusher cylinder, preventing displacement of the cylinder due to force during the driving process; the hinged connection can adapt to the angle changes during cylinder extension and retraction, preventing structural stress concentration caused by rigid connection. When the main pusher cylinder 81 extends and retracts, it can directly drive the main pusher shovel 6 to slide smoothly along the axial direction (towards or away from the discharge port) of the bottom plate 103 of the feeder body 1 through the extension and retraction of its own piston rod, realizing the pushing and resetting of the lower layer of garbage; similarly, the auxiliary pusher mounting base 92 provides a fixed support for the auxiliary pusher cylinder 91 that matches the installation height of the auxiliary pusher shovel 7, ensuring that the driving direction of the cylinder is consistent with the sliding direction of the auxiliary pusher shovel 7. It also adapts to the angle changes of cylinder extension and retraction through the hinged structure. When the auxiliary pusher cylinder 91 extends and retracts, it can drive the auxiliary pusher shovel 7 to slide along the axial direction of the auxiliary pusher mounting plate 104, completing the pushing and resetting of the upper layer of garbage, and working with the main pusher shovel 6 to realize the pushing of garbage in the double-layer space.

[0033] Furthermore, when the main push cylinder 81 is fully retracted, the front end of the main push shovel 6 stops at the middle position of the upper hollow area of ​​the feeding machine body 1; when the auxiliary push cylinder 91 is fully retracted, the front end of the auxiliary push shovel 7 stops at the edge line of the upper hollow area of ​​the feeding machine body 1 near the top plate 102; when the main push cylinder 81 is fully extended, the front end of the main push shovel 6 stops at the edge line of the lower bottom plate 103 of the feeding machine body 1; when the auxiliary push cylinder 91 is fully extended, the front end of the auxiliary push shovel 7 stops at the same position as the front end of the main push shovel 6 when the main push cylinder 81 is fully retracted.

[0034] It should be noted that when the main push cylinder 81 is fully retracted, the front end of the main push shovel 6 stops at the middle position of the upper hollow area of ​​the feeding machine body 1. This setting allows the main push shovel 6 to reserve a reasonable waste receiving area in the lower space, while freeing up sufficient working space for the upper auxiliary push shovel 7. This avoids the main push shovel 6 retracting too far back, resulting in insufficient lower layer receiving capacity, or extending too far forward, occupying the upper layer waste falling space, ensuring that both the upper and lower layers can stably receive waste falling from the hopper 2. When the auxiliary push cylinder 91 is fully retracted, the front end of the auxiliary push shovel 7 is flush with the edge line of the upper hollow area of ​​the feeding machine body 1 near the top plate 102 of the machine body. At this time, the auxiliary push shovel 7 retreats to the rearmost position in the upper space, maximizing the use of the upper space to receive waste and avoiding the upper layer receiving capacity being reduced due to the auxiliary push shovel 7 being positioned too far forward. The reduced volume ensures sufficient reception of upper-layer waste. When the main push cylinder 81 is fully extended, the front end of the main push shovel 6 is flush with the edge of the bottom plate 103 of the feeding machine body 1. This position allows the main push shovel 6 to completely push the waste in the lower space to the discharge port, avoiding waste residue in the lower layer due to the push shovel not extending to the edge of the bottom plate 103, and ensuring thorough material pushing in the lower layer. When the auxiliary push cylinder 91 is fully extended, the front end of the auxiliary push shovel 7 is flush with the front end of the main push shovel 6 when the main push cylinder 81 is fully retracted. This design allows the upper-layer waste pushed by the auxiliary push shovel 7 to connect with the lower-layer waste pushed by the main push shovel 6 in space, eliminating blind spots in material pushing between the upper and lower layers, and avoiding some waste not being pushed to the discharge port due to mismatch in the pushing range of the upper and lower push shovels, thus ensuring the integrity of the coordinated material pushing by the two-layer push shovels.

[0035] Furthermore, a material level sensor 12 is fixed on the upper part of the front side plate 101 of the feeding machine body 1. The detection end of the material level sensor 12 faces the inside of the feeding machine body 1 and can detect the accumulation height of the garbage inside the feeding machine body 1 in real time. A laser rangefinder sensor 11 is fixed on the inner side of the side plate 101 located directly behind the main push shovel 6 of the feeding machine body 1. The detection end of the laser rangefinder sensor 11 faces the main push shovel 6 and can detect the pushing length of the main push shovel 6 in real time.

[0036] It should be noted that the material level sensor 12 uses its own detection elements (such as infrared and ultrasonic sensors) to sense the accumulation of waste inside the machine in real time. When waste falls from the hopper 2 into the machine and gradually accumulates, the sensor can capture the change in the height of the waste accumulation, thereby determining whether the internal storage capacity of the machine has reached a reasonable level or whether unloading needs to be stopped to avoid excessive accumulation of waste and blockage. The laser rangefinder 11 emits a laser signal and receives the signal reflected from the surface of the main pusher shovel 6. It calculates the distance between the sensor and the main pusher shovel 6 based on the signal propagation time or phase difference. As the main pusher shovel 6 slides along the base plate 103 under the drive of the main pusher assembly 8, the change in distance can be directly converted into the extension length of the main pusher shovel 6, thereby accurately positioning the real-time position of the main pusher shovel 6 in the feeding machine body 1, ensuring that the pusher action meets the pushing requirements, and avoiding excessive extension or incomplete retraction of the pusher, which would affect the operation.

[0037] Furthermore, the side plates 101 on both sides of the feeding machine body 1 and the tail side plate 101 are provided with openable maintenance doors corresponding to the main push assembly 8 and the auxiliary push assembly 9. The maintenance doors 106 are hinged to the side plates 101 of the machine body via hinges.

[0038] It should be noted that when the main and auxiliary push components 9 need to be maintained (such as lubricating the oil cylinder, checking the roller wear) or repaired (such as replacing damaged parts), the key parts of the components can be directly accessed by opening the inspection door, without disassembling the overall structure of the feeding machine body 1, thus reducing the difficulty of operation.

[0039] Furthermore, the bottom plate 103 of the feeding machine body 1 is provided with several drainage holes, and a slag and water discharge outlet 107 is connected below the drainage holes. A slag and water filter bucket 10 is connected to the lower part of the slag and water discharge outlet 107. A filter plate with filter holes is provided at the bottom of the slag and water filter bucket 10, and an openable sealed slag cleaning port is provided on its side wall. A sewage discharge pipe is provided at the bottom.

[0040] It should be noted that wastewater containing slag is generated during the accumulation and pushing of waste inside the machine. The drain hole serves as a seepage channel for this slag-water mixture, preventing its accumulation on the surface of the bottom plate 103 and thus preventing obstruction of the pusher or corrosion of the bottom plate 103 due to water accumulation. The slag-water discharge outlet 107 connected below the drain hole can concentrate and guide the slag-water seeping from the drain hole to the slag-water filter hopper 10 below, preventing the slag-water mixture from scattering outside the machine during the guiding process and ensuring a concentrated slag-water collection path. The slag-water filter hopper 10 connected below the slag-water discharge outlet 107 is the core structure for achieving slag-water separation. The filter system features a perforated filter plate at the bottom that intercepts debris and impurities (such as small pieces and foreign objects) in the sludge and water, allowing wastewater to permeate downwards through the perforations and achieve initial separation of sludge and water. The side wall of the filter bucket has an openable, sealed cleaning port, which is normally sealed to prevent odor leakage and wastewater seepage. When a certain amount of residue accumulates on the filter plate, the cleaning port can be opened for easy removal of the trapped residue, ensuring continuous unobstructed flow. The wastewater discharge pipe at the bottom of the filter bucket guides the filtered wastewater to an external wastewater collection system for orderly discharge.

[0041] Furthermore, the main pusher 6 includes a pusher frame 601, pusher rollers 602, side guide sliders 604, roller cleaning plates 606, pusher scrapers 607, and scraper pressure plates 608. The pusher rollers 602 are symmetrically arranged at the bottom of the pusher frame 601, and the side guide sliders 604 are symmetrically arranged on both sides of the pusher frame 601, and can slide and cooperate with the inner sidewall of the feeding machine body 1 to guide the sliding direction of the main pusher 6. The roller cleaning plates 606 are correspondingly arranged on both sides of the pusher rollers 602, and the lower end of the roller cleaning plates 606 is in close contact with the surface of the bottom plate 103 of the feeding machine body 1, and can clean the slag and water on the path of the pusher rollers 602. The pusher scrapers 607 are arranged on both sides of the front pusher plate of the pusher frame 601 through the scraper pressure plates 608, and their outer sidewalls are in close contact with the inner sidewall of the feeding machine body 1 to form a flexible sealing cleaning and bonding surface.

[0042] It should be noted that the pusher frame provides an installation reference for various functional components (such as rollers and guide sliders) to ensure stable component layout; the length of the top plate is adapted to the pusher stroke, and when the pusher is pushed out, it can cover the space corresponding to the rear of the pusher in the upper hollow area of ​​the feeding machine body 1, preventing garbage from falling from above the pusher into the rear and affecting the operation; the front pusher plate directly contacts and pushes the garbage, converting the hydraulic cylinder driving force into pushing force; the bottom plate of the pusher moves in close contact with the bottom plate 103 of the feeding machine body 1, preventing garbage from returning to the rear from the bottom gap of the pusher, ensuring the integrity of the pushing; the pusher rollers 602 are symmetrically arranged at the bottom of the pusher frame 601, replacing the sliding friction between the bottom plate of the pusher and the bottom plate 103 of the machine body with rolling friction, reducing the resistance when the pusher slides, so that the main pusher 6 moves smoothly along the axial direction of the bottom plate 103 under the drive of the hydraulic cylinder, avoiding component wear or jamming caused by excessive sliding friction; the side guide slider 604 (can be made of nylon material) The pusher blades 602 and 606 are symmetrically arranged on both sides of the pusher frame 601 and slide against the inner wall of the feeding machine body 1. They limit the left and right deviation of the pusher blade during its extension and retraction, ensuring that the pusher blade always slides along the preset axis and preventing material deviation or component collision caused by pusher blade shaking. When the roller cleaning plate 606 slides synchronously with the pusher blade, it can scrape off the slag, water and small residues on the movement path of the pusher blade roller 602 in real time, preventing slag and water from seeping into the roller bearing or residue from jamming the roller, and ensuring that the roller continues to roll smoothly. The outer wall of the pusher blade scraper 607 (which can be made of polyurethane material) is close to the inner wall of the feeding machine body 1 to form a flexible and sealed cleaning surface. When the pusher blade pushes the material, it can prevent garbage from returning to the rear of the pusher blade from the gap between the pusher blade and the side plate 101 of the machine body, reducing the phenomenon of material return. The scraper blade pressure plate 608 ensures that the pusher blade scraper 607 is firmly connected to the front pusher plate through the fastening action, preventing the scraper blade from shifting or falling off when the material is pushed, and maintaining the sealing cleaning effect.

[0043] Furthermore, a roller adjusting pad 603 is provided between the pusher roller 602 and the pusher frame 601; a slider adjusting pad 605 is provided between the side guide slider 604 and the pusher frame 601.

[0044] It should be noted that the roller adjusting pad 603 can precisely control the installation height of the pusher roller 602 by adjusting its own thickness (or increasing or decreasing the number of pads), thereby finely adjusting the gap between the main pusher 6 frame base plate 103 and the feeder body 1 base plate 103. This ensures that when the main pusher 6 moves with the rollers, its frame can maintain a reasonable close distance with the base plate 103 to avoid a large amount of waste flowing back from the bottom, while also avoiding hard friction with the base plate 103 due to an excessively small gap. This achieves the best balance between low-resistance operation and effective sealing, and can compensate for manufacturing and assembly errors. By adjusting the thickness of the side guide slider 604, the lateral extension of the side guide slider 604 relative to the pusher frame 601 can be changed, thereby precisely controlling the fit clearance between the slider and the inner wall of the feeder body 1 side plate 101. This ensures that the main pusher shovel 6 can achieve effective lateral guidance through the slider during long-stroke reciprocating motion, preventing deviation, and also avoids sliding jamming due to too small a gap or shaking due to too large a gap, thus ensuring the smoothness and straightness of the pusher movement and extending the service life of the slider and side plate 101.

[0045] Furthermore, it also includes a support platform 3 and a maintenance platform 5. The feeding machine body 1 is fixed to the support platform 3 by its bottom support legs 108. The maintenance platform 5 is set on both sides of the hopper 2 and the tail of the feeding machine body 1, and is connected to the support platform 3 as a whole. The edge of the maintenance platform 5 is fixed with a protective railing. A ladder extending to the ground is also fixed on the maintenance platform 5 on one side of the feeding machine body 1.

[0046] It should be noted that the support platform 3, as the basic load-bearing structure of the equipment, provides stable support for the entire equipment, effectively resists the vibration and impact generated during operation, and ensures the stability of long-term operation; the maintenance platform 5 provides operators and maintenance personnel with a stable, continuous working plane that is higher than the ground, making it easy for them to access the hopper 2, the top and tail of the feeding machine 1 and other areas that need to be monitored or maintained.

[0047] The working principle and usage method of a garbage feeder with a double-layer pusher according to this embodiment:

[0048] This embodiment provides a garbage feeder with a double-layer pusher. The feeder body 1 provides an enclosed working space. The hopper 2 receives the garbage unloaded from the garbage collection vehicle and guides the garbage into the interior of the body. The auxiliary pusher mounting plate 104 divides the interior of the body into upper and lower layers to accommodate the double pusher operation. The auxiliary pusher assembly 9 drives the auxiliary pusher 7 to slide along the auxiliary pusher mounting plate 104, prioritizing the pushing of the upper layer of garbage to the discharge port. The partition on the auxiliary pusher 7 simultaneously seals the hollow area of ​​the body to prevent garbage from scattering. Subsequently, the main pusher assembly 8 drives the main pusher 6 to slide along the bottom plate 103 of the body, pushing the lower layer of garbage to the discharge port. The pushing ranges of the two are connected without blind spots, ensuring that the garbage is completely transported to the compression chamber docking hopper 105, which is sealed and connected to the discharge port, and finally enters the garbage compressor 4. Meanwhile, the material level sensor 12 monitors the height of the garbage accumulation inside the machine in real time, and the laser rangefinder 11 locates the position of the main push shovel 6, ensuring that the operation rhythm is controllable; the drainage hole of the machine bottom plate 103 works with the slag and water filter bucket 10 to achieve slag and water separation, avoiding sewage corrosion of equipment or obstruction of the push shovel sliding.

[0049] Before use, check whether the inspection doors on both sides and the tail end of the feeding machine body 1 are closed and sealed, whether the sealed slag cleaning port of the slag and water filter hopper 10 is locked, whether the filter plate is unobstructed, and whether the material level sensor 12 and the laser rangefinder sensor 11 are powered normally. Fix the feeding machine body 1 to the support platform 3 with the bottom support legs 108 to ensure that the machine body is level. You can climb the platform through the ladder on one side of the inspection platform 5 to check the docking status between the hopper 2 and the hollow area of ​​the machine body. Then the garbage collection truck dumps the garbage into the hopper 2. The garbage enters the feeding machine body 1 through the bottom of the hopper 2 and is naturally distributed in the upper and lower spaces of the auxiliary pusher plate 104. The material level sensor 12 installed on the side plate 101 of the machine body monitors the height of the internal garbage accumulation in real time. When the material level sensor 12 detects... When the garbage reaches the preset height, the control system automatically issues a command. The auxiliary pusher 7 cylinder moves first, driving the auxiliary pusher 7 to slide forward along the auxiliary pusher mounting plate 104, pushing the upper layer of garbage to the front of the machine body. Immediately afterwards, the main pusher 6 cylinder moves, driving the main pusher 6 to slide forward along the bottom plate 103 of the feeding machine body 1, pushing all the garbage gathered at the bottom layer forward as a whole. The laser range sensor 11 monitors the position of the main pusher 6 in real time to ensure that it is fully extended, pushing the garbage completely into the compression chamber docking hopper 105, and smoothly falling into the compression chamber of the garbage compressor 4. Finally, the main pusher 6 and the auxiliary pusher 7 retract to their respective initial positions in turn, ready to receive the next batch of garbage. Thus, a complete automated feeding cycle ends.
