Description

TECHNICAL FIELD

[0001] The present application relates to the field of waste disposal, and more particularly, to a waste compactor. BACKGROUND

[0002] A waste compactor is a commonly used device for collecting and transporting waste. Waste compactors are generally classified into push plate unloading type waste compactors and lifting unloading type waste compactors according to their unloading methods. The push plate unloading type waste compactor uses a push plate provided in the housing thereof to push the waste and then push the waste out of the housing. Since the push plate can directly act on the waste, it can effectively deal with the situation that the waste is frozen in the housing in winter. However, since there is inevitably a gap between the push plate and the housing, waste is often left behind the push plate, which is very difficult to clean and can contaminate and interfere with the power device. Therefore, the existing push plate unloading type waste compactor often has problems such as unclean unloading and accumulation of waste residues behind the push plate. The lifting unloading type waste compactor uses a lifting mechanism provided outside the housing to lift the housing so as to tilt the housing and make the waste leave the housing under the action of its own gravity. Therefore, it can reduce the residue of waste (especially sewage). However, since the housing needs to move up and down, it has a high requirement for the strength of the housing. Moreover, since it cannot directly act on the waste, it cannot effectively deal with the situation that the waste is frozen in the housing in winter. Therefore, the existing lifting unloading type waste compactor often has a heavy housing due to the welding of multiple reinforcing beams in the housing, which leads to a large energy consumption for moving the housing and may not be able to effectively discharge waste in winter. In addition, it is worth mentioning that in the prior art, a specific housing needs to be produced according to the type of the waste compactor. Once the housing is produced, it can only be assembled into a waste compactor of a certain type, so it cannot mass-produce the same housing for waste compactors of various types, which leads to a high production cost and poor versatility of the housing of the existing waste compactor.

[0003] Therefore, there is an urgent need in the art for a waste compactor with high versatility and capable of effectively discharging waste to reduce waste residue. SUMMARY

[0004] To solve the above problems in the prior art, the present application provides a waste compactor, which comprises:

[0005] a housing defining a chamber inside, the chamber extending along a horizontal direction between a chamber front end and a chamber rear end; and

[0025] Further features and advantages of the application will become apparent from the following description, with reference to the drawings. In the drawings, exemplary embodiments of the application are shown, and the various drawings are not necessarily drawn to scale. However, the application can be embodied in many different forms and should not be construed as necessarily limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided merely for illustrative purposes and to convey the spirit and scope of the present application to those skilled in the art.

[0026] The present application aims to provide an improved garbage compressor that can collect and transport garbage. In particular, the garbage compressor can be assembled on a vehicle to form a mobile garbage collection vehicle that can travel to residential areas, commercial areas, industrial areas, etc. to collect residential garbage, kitchen garbage, industrial garbage, etc. The garbage compressor is provided with a garbage inlet at the top of the housing for receiving garbage and a garbage outlet at the front end of the housing for discharging garbage. In particular, the housing of the garbage compressor is provided with various engagement sites inside and outside, which can engage a pushing mechanism to form a pusher discharge type garbage compressor. In the pusher discharge type garbage compressor, the pushing mechanism can be activated during loading to push the garbage falling from the garbage inlet into the housing towards the garbage outlet to prevent the garbage from accumulating below the garbage inlet, and the pushing mechanism can also be activated during unloading to push the garbage out of the garbage outlet. In addition, the engagement sites can also engage a lifting cylinder and a scraper mechanism to form a lifting discharge type garbage compressor. In the lifting discharge type garbage compressor, the scraper mechanism can be activated during loading to swing back and forth below the garbage inlet to prevent the garbage from accumulating below the garbage inlet, and the lifting cylinder can be activated during unloading to lift the rear end of the housing and tilt the garbage outlet at the front end downward, so that the garbage falls out of the garbage outlet to the outside of the housing under the action of its own gravity. In addition, the engagement sites can also be used in combination, for example, both the pushing mechanism and the lifting cylinder are combined to the housing to form a hybrid type garbage compressor. In the hybrid type garbage compressor, both the pushing mechanism can be used to reliably move the garbage in the housing, and the lifting cylinder can be used to lift the housing to more effectively discharge the garbage in the housing. Therefore, the present garbage compressor can be formed into various types of garbage compressors by having a housing with a novel configuration, and can be converted between various types, which enables mass production of the same type of housing for various types of garbage compressors, and then various additional mechanisms are assembled on the housing according to the requirements of customers to form the desired type of garbage compressor. Therefore, compared with the existing housing that can only be assembled into a specific type of garbage compressor, the housing of the garbage compressor according to the present application has higher adaptability and flexibility, allowing mass production to reduce production costs, and can be assembled into various types of garbage compressors according to customer requirements, and even allows the type of garbage compressor to be converted.

[0027] Various embodiments of the garbage compressor according to the present application are described in detail below with reference to the accompanying drawings. In the various drawings, the vertical direction (may also be referred to as the height direction) is indicated by arrows VV', in which arrow V points upward, and arrow V' points downward; the horizontal direction (may also be referred to as the length direction) is indicated by arrows HH', in which arrow H points forward, and arrow H' points backward; and the transverse direction (may also be referred to as the width direction) is indicated by arrows TT', in which arrow T points to the left, and arrow T' points to the right. However, it should be noted that the above orientation terms are merely intended to more intuitively describe the relative orientations of the various components involved in the technical solutions defined by the present application in conjunction with the drawings, and not the absolute orientations of the various components, which should not be interpreted in any way as a limitation on the scope of protection of the present application.

[0028] Reference is made to Figure 1 , which shows a schematic perspective view of a housing of a garbage compressor according to the present application. As shown in Figure 1 , the garbage compressor comprises a housing 100, the inner surface of which defines a chamber 110 for accommodating garbage, a garbage inlet 120 for receiving garbage is provided at the top of the chamber 110, and a garbage outlet 130 for discharging garbage is provided at the front end of the chamber 110. In this configuration, during loading, a device for storing garbage such as a garbage bin can be lifted above the garbage compressor, and then the garbage therein can be poured into the chamber 110 through the garbage inlet 120; while during unloading, the garbage can be discharged from the chamber 110 through the garbage outlet 130. In particular, the housing 100 can further comprise a top cover provided at the top thereof for opening and closing the garbage inlet 120, and an end cover provided at the front end thereof for opening and closing the garbage outlet 130. In this configuration, the top cover can be opened only during loading, and the end cover can be opened only during unloading, whereby the chamber 110 can be closed when other operations (e.g., storage, transfer of garbage) are performed, so as to avoid the escape of garbage and its generated sewage, odor, etc. through the garbage inlet 120 and the garbage outlet 130, which helps to protect the environment from being polluted by garbage.

[0029] Reference is made to Figure 2 , which shows a schematic perspective view of Figure 1 the housing. As shown in Figure 1 and Figure 2As shown, one or more grooves 113 are formed in the bottom 112 of the chamber 110, which extend along the horizontal direction HH', in particular, from the rear end 111 of the chamber 110 to the garbage outlet 130. As shown, the chamber 110 extends along the horizontal direction HH' between the rear end 111 and a front end, and has a circumferential edge (referred to as the periphery, i.e., the inner surface of the housing 100) between the rear end 111 and the front end, which defines the cross-sectional shape of the chamber 110, and the top, bottom and sides of the chamber 110 are all part of the periphery. In particular, a porous filter plate 114 is covered on each groove 113, at this time, the porous filter plate 114 can be regarded as part of the bottom 112 of the chamber 110. In particular, the porous filter plate 114 is sized and shaped to be aligned (or flush) with the bottom 112 of the chamber 110. In this configuration, the porous filter plate 114 can allow sewage to enter the groove 113, but prevent solid garbage from entering the groove 113, so that the garbage in the chamber 110 is separated from the sewage, which helps to avoid the garbage from being smelly and breeding bacteria and viruses due to long-term soaking in sewage, and also helps to avoid the push plate, driving device, etc. from being prematurely aged and damaged due to long-term soaking in sewage. In addition, compared with the way of reinforcing the strength of the housing in the prior art by welding reinforcing beams on the bottom of the housing, the grooves 113 provided on the bottom of the chamber not only enhance the strength of the bottom of the housing, but also reduce the weight of the housing, so that the energy consumption required for moving the housing is greatly reduced. In particular, as shown in Figure 1 As shown, a groove 115 can also be provided in the bottom 112 of the chamber 110, which extends along the transverse direction TT' to communicate the grooves 113 with each other. In addition, a through hole communicating with the outside can be provided at the bottom of the groove 115 and a drain valve can be provided in the through hole. In this configuration, sewage in each groove 113 can be discharged by only opening the drain valve at the bottom of the groove 115, and thus the sewage in the chamber 110 can be discharged. This configuration is advantageous because the drain valve can be opened before the garbage outlet 130 is opened to discharge the garbage in the chamber 110, so as to discharge the sewage in the chamber 110 first, that is, this configuration allows the sewage and the garbage to be discharged and collected separately. In particular, the grooves 113 can be arranged to have an increasing depth as they approach the garbage outlet 130 or the groove 115 (if present), that is, the grooves 113 are provided to have a slope, which is beneficial for discharging the sewage in the grooves 113.

[0030] As shown in Figure 1 and Figure 2 In order to guide the push plate of the push mechanism described below, one or more guide rails 116 extending along the horizontal direction HH' are provided on the inner surface of the housing 100 (i.e., the side wall of the chamber 110). In particular, with reference to Figure 3, which shows a cross-sectional view of two guide rails 116 located on two opposite side walls 160 of the chamber 110, as shown in FIG. Figure 3 As shown, the housing 100 includes a pair of side walls 160 spaced apart along the transverse direction TT'. Each side wall 160 includes an upper side wall 161 and a lower side wall 162. The lower end of the upper side wall 161 is bent into a C-shaped cross-section with an opening facing outward, thereby forming the guide rail 116. The upper end of the lower side wall 162 is received in the opening of the C-shaped cross-section and is formed to conform to the lower end of the upper side wall 161, so that the upper end of the lower side wall 162 contacts (fits with, abuts) the lower end of the upper side wall 161 in the opening. In addition, the upper end of the lower side wall 162 and the lower end of the upper side wall 161 can be fixed together by welding, bonding, etc. It is worth mentioning that the shell of a garbage compactor is generally large in size, so its side walls often need to be spliced ​​together with multiple plates. In the prior art, two plates are generally spliced ​​and welded together to form the side wall, and then additional guide rails are welded on the inner surface of the side wall. However, welding the guide rails may cause the welded plates to deform or even leak at the joints. The above configuration solves this problem because after the upper side wall 161 and the lower side wall 162 are welded together, the guide rail 116 is already formed at the lower end of the upper side wall 161, and there is no need to weld additional guide rails. Figure 3 As shown, there is a large contact (welding) area between the upper side wall 161 and the lower side wall 162, which can effectively prevent leakage from occurring at the joint between the upper side wall 161 and the lower side wall 162. Moreover, since the ends of the upper side wall 161 and the lower side wall 162 can be regarded as being intertwined with each other, the strength of the side wall 160 is significantly increased. In particular, as shown in FIG. Figure 3 As shown, in the opening of the C-shaped cross-section, an L-shaped contact area a is formed between the lower end of the upper side wall 161 and the upper end of the lower side wall 162. Of course, the upper end of the lower side wall 162 can be further bent to form the contact area a into a C-shape. More specifically, an additional contact area b is formed between the lower end of the upper side wall 161 and the inner surface of the lower side wall 162. Although the above description describes that the lower end of the upper side wall 161 is formed to have a C-shaped cross-section and the upper end of the lower side wall 162 is formed to conform to the C-shaped cross-section, it will be understood by those skilled in the art that, alternatively, the upper end of the lower side wall 162 can also be formed to have a C-shaped cross-section, and the lower end of the upper side wall 161 can be formed to conform to the C-shaped cross-section, which is obviously also within the scope of protection of the present invention.

[0031] like Figures 1-5 As shown, the housing 100 may be provided with a plurality of joints, wherein each joint is used to join an additional mechanism so as to assemble the additional mechanism to the housing 100 , thereby producing various types of garbage compactors.

[0032] In particular, Figure 4 As shown, a schematic side view of a garbage compactor according to an embodiment of the present invention is shown, the shell 100 may be provided with a first joint at its rear end, and the first joint is provided with an external joint 140 for engaging a lifting mechanism (e.g., a hydraulic cylinder, a pneumatic cylinder, a screw, etc.), wherein one end of the lifting mechanism may be hinged to a fixed position (e.g., a base fixed on a vehicle), and the other end thereof may be hinged to the external joint 140, and therefore, the first joint may also be referred to as a lifting portion. After assembly is completed, the lifting mechanism may lift the rear end of the shell 100 and tilt the garbage outlet 130 at the front end of the shell 100 downward, so that the garbage will be discharged from the chamber 110 through the garbage outlet 130 under the action of its own gravity. This method of unloading by lifting the shell is generally referred to as lifting unloading. In particular, as Figure 4 As shown, the housing 100 may also be provided with a second joint portion 150 on its top for engaging the scraper mechanism 200. The second joint portion 150 may be provided with a plurality of mounting holes. The base 210 of the scraper mechanism 200 may be removably assembled to the second joint portion 150 by fixing members (e.g., screws, etc.) passing through these mounting holes. Therefore, the second joint portion 150 may also be referred to as a scraper portion. It will be appreciated by those skilled in the art that the base 210 of the scraper mechanism 200 may also be assembled to the second joint portion 150 by a non-removable method such as welding or bonding. In this case, the second joint portion 150 does not need to be provided with mounting holes. After assembly, the scraper 220 of the scraper mechanism 200, which is hinged to the base 210, can swing below the garbage inlet 120 (e.g., around an axis extending along the transverse direction TT') to prevent garbage from accumulating below the garbage inlet 120 and thereby blocking the garbage inlet 120, thereby helping to ensure smooth loading. In operation, during loading, the lifting mechanism can be deactivated and the scraper mechanism 300 can be activated to keep the housing 100 level and push the garbage away from under the garbage inlet 120; during unloading, the lifting mechanism can be activated and the scraper mechanism 300 can be deactivated to tilt the garbage outlet 130 downward to discharge the garbage.

[0033] In particular, Figure 5As shown in FIG. 1 1, in which a schematic perspective view of a trash compactor according to another embodiment of the present application is shown, the housing 100 can be provided with a third joint site at the rear end 1 1 1 of the chamber 1 10, which can be provided with an internal joint (not shown) to which one end of a driving device (e.g., a hydraulic cylinder, a pneumatic cylinder, a lead screw, etc.) of the pushing mechanism 300 can be articulated, while the other end of the driving device can be articulated to a pushing plate 310 of the pushing mechanism 300, thus the third joint site can also be referred to as a pushing site. In this configuration, as the driving device extends and retracts, the pushing plate 310 will reciprocate along a horizontal direction HH' (e.g., along the guide rail 1 16) between a first position PI that is close to the rear end 1 1 1 of the chamber 1 10 and a second position P2 that is away from the rear end 1 1 1 of the chamber 1 10, where the first position PI can be located behind the trash inlet 120, while the second position P2 can be located in front of the trash inlet 120, particularly, close to the trash outlet 130. Thus, the pushing plate 310 can push the trash that falls onto the bottom 1 12 of the chamber 1 10 from the trash inlet 120 towards the trash outlet 130, so as to prevent the trash from piling up below the trash inlet 120 when loading, and to push the trash out of the trash outlet 130 when unloading, this way of unloading by pushing the trash with a pushing plate is commonly referred to as pushing plate unloading. Particularly, the edge (i.e., the periphery) of the pushing plate 310 can be sized and shaped such that the entire edge of the pushing plate 310 is adjacent to the inner surface of the housing 100 (i.e., the periphery of the chamber 1 10), which helps to effectively push the trash towards the trash outlet 130, and prevents most of the trash, particularly the larger ones, from reaching the rear of the pushing plate 310 through the gap between the edge of the pushing plate 310 and the inner surface of the housing 100. This configuration is advantageous because the trash that reaches the rear of the pushing plate 310 will contaminate the driving device, or even interfere with the operation of the driving device, and is very difficult to clean. Particularly, the pushing mechanism 300 can further include a resilient plate (e.g., a rubber sheet) 320 arranged around the edge of the pushing plate 310, where the edge of the pushing plate 310 can be sized and shaped to be spaced apart from the inner surface of the housing 100, while the resilient plate 320 can be sized and shaped to abut against the inner surface of the housing 100, so as to close the gap between the edge of the pushing plate 310 and the inner surface of the housing 100, thus the trash can be pushed more effectively towards the trash outlet 130, while the wear of the two rigid structures, the pushing plate 310 and the housing 100, is reduced. Particularly, the resilient plate 320 can isolate the front and the rear of the pushing plate 310, thus more reliably avoiding the trash from reaching the rear of the pushing plate 310, especially when both the trash inlet 120 and the trash outlet 130 are closed, the front and the rear of the pushing plate 310 can be formed as two sealed environments that are isolated from each other by the resilient plate 320.In particular, the front surface 311 of the push plate 310 is arranged at an angle, and when the push plate 310 is located at the first position P1, the garbage inlet 120 is aligned with the front surface 311, so that the garbage entering the chamber 110 through the garbage inlet 120 will fall onto the front surface 311 and slide down to the front of the push plate 310 under its guidance, which helps to avoid splashing caused by the garbage falling directly onto the bottom 112 of the chamber 110. In operation, during loading, the garbage inlet 120 can be opened and the garbage outlet 130 can be closed, and then the garbage can be dumped into the garbage inlet 120. At this time, the push plate 310 can be placed in the first position P1. After stopping the dumping, the push plate 310 can be moved to the second position P2 to push the garbage toward the garbage outlet 130. Then, the push plate 310 can be moved back to the first position P1 and continue dumping the garbage. Repeat the above operation until the box is full; during unloading, the garbage inlet 120 can be closed and the garbage outlet 130 can be opened, and then the push plate 310 can be moved to the second position P2 to push the garbage out of the garbage outlet 130.

[0034] As mentioned above, the housing 100 can be combined with the lifting mechanism and the scraper mechanism 200 to form a Figure 4 The lifting and unloading garbage compactor shown in FIG. 3 can be combined with the pushing mechanism 300 to form a Figure 5 The illustrated push-plate unloading garbage compactor, wherein the lift-unloading garbage compactor can more thoroughly discharge the garbage, especially the sewage, within the housing, thereby reducing the residual garbage and sewage. However, since the housing needs to move up and down, the strength of the housing (especially the strength of the bottom of the housing) is required to be relatively high. As described above, the presence of the groove 113 both reduces the weight of the housing and increases the strength of the bottom of the housing. Therefore, the lift-unloading garbage compactor obtained according to the technical solution of the present invention has outstanding performance advantages compared with the prior art. Since the push plate directly acts on the garbage during unloading, the push-plate unloading garbage compactor can effectively deal with the situation where garbage freezes within the housing in winter. However, due to the inevitable gap between the push plate and the inner surface of the housing, the garbage (especially the sewage) may not be effectively discharged, and some small-sized garbage may pass through these gaps and reach behind the push plate. Once these small-sized garbage reach the rear of the push plate, they will be very difficult to clean up and may even interfere with the operation of the drive device. In addition, they may cause the rear of the push plate 310 to expand when the push plate 310 returns to the first position P1. However, as described below, the push plate unloading type garbage compactor obtained according to the technical solution of the present invention successfully solves this problem. Figure 2 、 Figure 5 and Figure 6 The advantages of the push plate unloading type garbage compactor obtained according to the technical solution of the present invention are described.

[0035] like Figure 2and Figure 5 As shown, the groove 113 has a rear end 117 and a front end 118 spaced apart along the horizontal direction HH', that is, the distance between the rear end 117 and the front end 118 of the groove 113 defines the length of the groove 113, however, the porous filter plate 114 does not cover the entire (or all) length of the groove 113, but leaves an uncovered open portion near the rear end 117 of the groove 113. In the case shown in the figure, the porous filter plate 114 extends from the front end 118 of the groove 113 to a terminal position spaced apart from the rear end 117 of the groove 113, so that the groove 113 is not covered by the porous filter plate 114 or has an open portion between the terminal position and the rear end 117. In particular, the first position PI of the push plate 310 closer to the chamber rear end 111 is positioned between the terminal position of the porous filter plate 114 and the front end 118 of the groove 113, that is, the push plate 310 cannot be moved towards the chamber rear end 111 to a position such that the open portion of the groove 113 appears in front of the push plate 310, in other words, the open portion of the groove 113 is always located behind the push plate 310, and the portion of the groove 113 in front of the push plate 310 is always covered by the porous filter plate 114. In this configuration, when the push plate 310 moves to the second position P2, the air pressure in front of the push plate 310 increases, and the air pressure behind the push plate 310 decreases, at this time, the sewage in front of the push plate 310 will be pressed into the rear of the push plate 310 through the groove 113, and due to the presence of the porous filter plate 114, the garbage in front of the push plate 310 cannot enter the groove 113, and the sewage entering the groove 113 will flow out from the portion of the groove 113 behind the push plate 310 (especially the open portion), and then the sewage flow will lift and mix with the garbage behind the push plate 310; when the push plate 310 returns to the first position PI, the air pressure in front of the push plate 310 decreases, and the air pressure behind the push plate 310 increases, at this time, the sewage behind the push plate 310 will be pressed into the front of the push plate 310 through the groove 113, and the sewage tends to flow into the open portion of the groove 113, and the open portion does not hinder the garbage from entering, therefore, the sewage flow will carry the garbage into the open portion and through the groove 113 to the front of the push plate 310. Therefore, the above configuration combined with the movement of the push plate 310 causes the sewage flow to circulate in front of and behind the push plate 310, and this circulation of the sewage flow can carry the garbage behind the push plate 310 to the front of the push plate 310, thereby effectively solving the problem of garbage not being easily cleaned behind the push plate 310. It is worth mentioning that as long as the garbage behind the push plate 310 is flushed into the groove 113, it is already beneficial to discharge the garbage behind the push plate 310. In addition, the higher the degree of closure of the garbage inlet 120 and the garbage outlet 130, the more completely the push plate 310 separates the front and rear thereof, the more beneficial it is to form the self-circulation of the sewage flow, and thus more effectively clean the garbage behind the push plate 310.

[0036] In particular, if Figure 6 As shown, a blocking structure can be provided in the groove 113. The front surface 119 of the blocking structure, facing forward, has a relatively large slope, while the rear surface, facing backward, has a relatively small slope, or even zero slope. In this configuration, the front surface 119 of the blocking structure can block the backward movement of trash in the sewage flow, while the rear surface does not block the forward movement of trash in the sewage flow. This further facilitates the removal of trash behind the push plate 310 and reduces the amount of trash that returns to the rear of the push plate 310. In particular, the front surface 119 can be provided by varying the depth or cross-sectional shape of the groove 113, or by providing a separate blocking block in the groove 113.
