Description

Technical Field

[0001] This invention relates to the field of waste collection and transfer technology, and more specifically, to a self-cleaning garbage bin and a garbage truck. Background Technology

[0002] Compactor garbage trucks are the main vehicle equipment for collecting and transporting municipal solid waste in urban areas. They consist of a garbage bin and a pusher that slides inside the bin. The pusher pushes the compressed garbage outward from the bin to achieve the garbage transfer function. However, during garbage collection and transfer, some garbage moves from the gap between the pusher and the bin to the front of the bin under the compression force. This garbage cannot be pushed out by the pusher and must be manually cleaned inside the bin, which is time-consuming, labor-intensive, has low cleaning efficiency, poor cleaning effect, and produces a strong odor inside the bin, making the working environment extremely harsh and affecting the health of workers.

[0003] In view of this, it is particularly important to design and manufacture a self-cleaning garbage bin and garbage truck with high cleaning efficiency, good cleaning effect and high safety, especially in garbage collection and transportation. Summary of the Invention

[0004] The purpose of this invention is to provide a self-cleaning trash can that can self-clean the trash at the front of the can without requiring manual entry into the can. It has a high degree of mechanization, saves time and labor, has high cleaning efficiency, good cleaning effect, and high safety.

[0005] Another objective of this invention is to provide a garbage truck that can achieve self-cleaning of garbage at the front of the container without requiring manual entry into the container. It has a high degree of mechanization, saves time and labor, has high cleaning efficiency, good cleaning effect, and high safety.

[0006] The present invention is achieved by the following technical solution.

[0007] A self-cleaning trash can includes a can body, a first driving component, a pusher, and a cleaning mechanism. The first driving component is installed inside the can body and connected to the pusher. The pusher is slidably disposed inside the can body. The cleaning mechanism is installed inside the can body. The can body has a tail opening. The first driving component is used to drive the pusher to slide towards the tail opening to push the trash inside the can body out of the tail opening. The first driving component is also used to drive the pusher to extend out of the tail opening so that the pusher is spaced apart from the bottom wall of the tail opening and forms a flow gap. The cleaning mechanism is used to clean the inside of the can body so that residual trash and cleaning liquid are discharged from the flow gap.

[0008] Optionally, the box body is provided with a limiting structure, which is located inside the tail opening. The pusher is provided with a matching structure. The limiting structure is used to cooperate with the matching structure when the pusher extends out of the tail opening to limit the pusher.

[0009] Optionally, the limiting structure is one of a hook and a latch, and the mating structure is the other of a hook and a latch. The mating structure is used to engage with the limiting structure when the pusher extends out of the tail opening, so that the pusher can rotate relative to the limiting structure. One end of the first driving component is rotatably connected to the housing, and the other end is rotatably connected to the pusher. The first driving component is used to drive the pusher to extend out of the tail opening and rotate relative to the limiting structure.

[0010] Optionally, there are two limiting structures and two mating structures. The two limiting structures are arranged opposite each other on both sides of the housing, and each limiting structure is connected to a mating structure.

The second drive component is installed on the pusher body and connected to the guide slide structure. A slide is provided inside the housing, and the guide slide structure is slidably engaged with the slide. The second drive component is used to drive the guide slide structure to move when the pusher extends out of its tail end, so as to release the engagement state between the guide slide structure and the slide.

[0012] Optionally, the guide structure includes a guide top plate, a connecting plate, and a guide bottom plate. The guide top plate and the guide bottom plate are disposed opposite to each other on both sides of the connecting plate. The slide is slidably disposed between the guide top plate and the guide bottom plate. The pusher body is fixedly connected to the connecting plate through the guide top plate. The connecting plate is rotatably connected to the guide bottom plate. One end of the second driving member is rotatably connected to the pusher body, and the other end is rotatably connected to the guide bottom plate. The second driving member is used to drive the guide bottom plate to rotate relative to the connecting plate, so as to separate the guide bottom plate from the slide.

[0013] Optionally, there are two second drive components, two guide structures, and two slides. The two slides are arranged opposite each other on both sides of the housing. Each second drive component is connected to a guide structure, and each slide is slidably engaged with a guide structure. The first drive component is located in the middle between the two slides.

[0014] Optionally, the cleaning mechanism includes a storage tank, a water pump, and a water pipe. The water pump is installed in the storage tank and connected to the water pipe. The water pipe is equipped with a nozzle. The water pump is used to draw the cleaning liquid from the storage tank into the water pipe, and the nozzle is used to spray the cleaning liquid into the tank.

[0015] Optionally, the self-cleaning trash can also include a controller, a position sensor, and a vision sensor. The controller is electrically connected to the position sensor, the vision sensor, and the water pump. The position sensor is used to detect the movement position of the pusher, the vision sensor is used to detect the amount of residual trash inside the can, and the controller is used to control the water pump to start when a flow gap is formed between the pusher and the bottom wall of the tail opening and the amount of residual trash reaches a preset threshold, so as to clean the inside of the can.

[0016] A garbage truck includes a frame and the aforementioned self-cleaning garbage bin. The self-cleaning garbage bin includes a bin body, a first drive unit, a pusher, and a cleaning mechanism. The bin body is mounted on the frame. The first drive unit is mounted inside the bin body and connected to the pusher. The pusher is slidably disposed inside the bin body. The cleaning mechanism is installed inside the bin body. The bin body has a tail opening. The first drive unit is used to drive the pusher to slide towards the tail opening to push the garbage inside the bin body out of the tail opening. The first drive unit is also used to drive the pusher to extend out of the tail opening so that the pusher is spaced apart from the bottom wall of the tail opening and forms a flow gap. The cleaning mechanism is used to clean the inside of the bin body so that residual garbage and cleaning fluid are discharged from the flow gap.

[0017] The self-cleaning garbage bin and garbage truck provided by this invention have the following beneficial effects: The self-cleaning trash can provided by this invention has a first driving component installed inside the can and connected to a pusher. The pusher is slidably disposed inside the can. A cleaning mechanism is also installed inside the can. The can has a tail opening. The first driving component drives the pusher to slide towards the tail opening, pushing the trash inside the can out of the tail opening. The first driving component also drives the pusher to extend beyond the tail opening, so that the pusher is spaced apart from the bottom wall of the tail opening, forming a flow gap. The cleaning mechanism cleans the inside of the can, allowing residual trash and cleaning fluid to drain through the flow gap. Compared with the prior art, the self-cleaning trash can provided by this invention, due to the use of a first driving component connected to the pusher and a cleaning mechanism installed inside the can, can achieve self-cleaning of trash at the front of the can, eliminating the need for manual entry into the can. It has a high degree of mechanization, saves time and labor, has high cleaning efficiency, good cleaning effect, and high safety.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, features in the following embodiments can be combined with each other.

[0028] Please refer to the reference. Figures 1 to 10 This invention provides a garbage truck 10 for collecting and transporting garbage. It is capable of self-cleaning the garbage at the front of the container 110 without requiring manual entry into the container 110. It has a high degree of mechanization, saves time and labor, has high cleaning efficiency, good cleaning effect, and high safety.

[0029] It should be noted that the garbage truck 10 includes a frame 300 and a self-cleaning garbage container 100. The self-cleaning garbage container 100 is mounted on the frame 300 and is used to collect and unload garbage. The frame 300 is used to drive the self-cleaning garbage container 100 to move, thereby realizing the garbage transfer function.

[0030] The self-cleaning trash can 100 includes a body 110, a first drive component 120, a pusher 130, and a cleaning mechanism 140. The body 110 is mounted on a frame 300, which limits and secures the body 110. The first drive component 120 is installed inside the body 110 and connected to the pusher 130, which is slidably disposed within the body 110. The first drive component 120 drives the pusher 130 to slide relative to the body 110, and the body 110 limits the movement of the pusher 130. Specifically, the cleaning mechanism 140 is installed inside the housing 110, which has a tail opening 111. The first driving member 120 is used to drive the pusher 130 to slide towards the tail opening 111, so as to push the garbage in the housing 110 out of the tail opening 111, thereby realizing the unloading function of most of the garbage. The first driving member 120 is also used to drive the pusher 130 to extend out of the tail opening 111, so that the pusher 130 is spaced apart from the bottom wall of the tail opening 111 and forms a flow gap 150. The cleaning mechanism 140 is used to clean the inside of the housing 110, so that the residual garbage and cleaning liquid are discharged from the flow gap 150, thereby realizing the unloading function of the remaining small part of the garbage and the cleaning function of the housing 110.

[0031] Understandably, when the self-cleaning trash can 100 collects trash, the pusher 130 is initially positioned at the front end of the can body 110 (the end furthest from the tail opening 111). At this time, most of the trash is compressed and piled up on the side of the pusher 130 near the tail opening 111. However, a small portion of the trash will move from the gap between the pusher 130 and the can body 110 to the side of the pusher 130 furthest from the tail opening 111 under the squeezing action. For ease of description, this portion of trash is referred to as the trash at the front end of the can body 110. When the self-cleaning trash can 100 unloads trash, the first drive member 120 drives the pusher 130 to slide towards the tail opening 111, so as to push most of the trash out of the tail opening 111. However, since the trash at the front end of the can body 110 is located on the side of the pusher 130 furthest from the tail opening 111, the pusher 130 cannot push it out. Furthermore, the pusher 130 located inside the can body 110 will also block the trash at the front end of the can body 110, preventing it from leaving the can body 110 from the tail opening 111.

[0032] In this regard, in the self-cleaning trash can 100 of the present invention, after the first driving member 120 pushes the pusher 130 to the position of the tail opening 111 to push out most of the trash from the tail opening 111, the first driving member 120 can also drive the pusher 130 to continue to move and extend out of the tail opening 111, so that the pusher 130 and the bottom wall of the tail opening 111 are spaced apart and a flow gap 150 is formed. At this time, the pusher 130 no longer stops the trash at the front of the can body 110, and the trash at the front of the can body 110 can leave the can body 110 from the tail opening 111. Furthermore, after the first driving component 120 drives the pusher 130 to extend out of the tail opening 111, the cleaning mechanism 140 installed inside the container 110 cleans the inside of the container 110. On the one hand, it flushes out the garbage at the front of the container 110, realizing the unloading function of the garbage at the front of the container 110. On the other hand, it cleans the inside of the container 110 to prevent sewage and dirt in the garbage from corroding the container 110 and to ensure the service life of the container 110. In this way, the self-cleaning garbage container 100 can achieve self-cleaning of the garbage at the front of the container 110 without the need for manual entry into the container 110. It has a high degree of mechanization, saves time and labor, has high cleaning efficiency, good cleaning effect, and high safety.

[0033] Optionally, the housing 110 is provided with a limiting structure 112, which is located inside the tail opening 111. The pusher 130 is provided with a cooperating structure 131. The limiting structure 112 is used to cooperate with the cooperating structure 131 when the pusher 130 extends out of the tail opening 111 to limit the pusher 130, prevent the pusher 130 from falling downward under the action of gravity after extending out of the tail opening 111, and thus prevent damage to the first driving member 120, thereby improving the stability of the pusher 130 during the process of extending or retracting out of the tail opening 111.

[0034] Optionally, the limiting structure 112 is either a hook or a buckle, and the mating structure 131 is either a hook or a buckle. The mating structure 131 is used to engage with the limiting structure 112 when the pusher 130 extends out of the tail opening 111, so that the pusher 130 can rotate relative to the limiting structure 112, thereby forming a flow gap 150 between the pusher 130 and the bottom wall of the tail opening 111. Specifically, one end of the first driving member 120 is rotatably connected to the housing 110, and the other end is rotatably connected to the pusher 130. The first driving member 120 is used to drive the pusher 130 to slide within the housing 110. The first driving member 120 is also used to drive the pusher 130 to extend out of the tail opening 111 and rotate relative to the limiting structure 112.

[0035] Furthermore, during the unloading process of the self-cleaning garbage bin 100, the first driving member 120 first drives the pusher 130 to slide within the bin body 110 towards the tail opening 111. At this time, since the bin body 110 can limit the pusher 130, the pusher 130 can only slide in a straight line, while the first driving member 120 extends along the sliding direction of the pusher 130 and will not rotate relative to the bin body 110 and the pusher 130; when the pusher 130 slides to the position of the tail opening 111, the cooperating structure 131... When connected to the limiting structure 112, the housing 110 can limit the pusher 130 through the engagement of the mating structure 131 and the limiting structure 112; then the first driving member 120 drives the pusher 130 to extend out of the tail opening 111, so that the pusher 130 rotates upward around the limiting structure 112. At this time, since the pusher 130 has a height change in the vertical direction, the first driving member 120 will rotate relative to the housing 110 and the pusher 130 at the same time, that is, the first driving member 120 will be inclined to the bottom wall of the housing 110.

[0036] Optionally, there are two limiting structures 112 and two mating structures 131. The two limiting structures 112 are arranged opposite each other on both sides of the housing 110, and the two mating structures 131 are arranged opposite each other on both sides of the pusher 130. Each limiting structure 112 is engaged with one mating structure 131. Specifically, the two limiting structures 112 and the two mating structures 131 work together to ensure the stability and balance of the pusher 130 as it rotates upward relative to the limiting structures 112, preventing the pusher 130 from detaching from the housing 110 and improving safety.

[0037] Optionally, the mating structure 131 is disposed on the top of the pusher 130 to facilitate the mating of the limiting structure 112 and the mating structure 131, thereby enabling the pusher 130 to rotate upward relative to the limiting structure 112 after extending out of the tail opening 111; the first driving member 120 is connected to the bottom of the pusher 130 to apply a stable thrust to the pusher 130 and improve the stability of the pusher 130 sliding.

[0038] In this embodiment, the limiting structure 112 and the cooperating structure 131 are engaged to enable the pusher 130 to rotate relative to the box 110 after extending out of the tail opening 111. However, this is not the only embodiment. In other embodiments, the limiting structure 112 and the cooperating structure 131 can also be engaged, and the pusher 130 can continue to move in a straight line without rotating after extending out of the tail opening 111. The specific limitations are not imposed on the cooperating method of the limiting structure 112 and the cooperating structure 131 or the movement method of the pusher 130 after extending out of the tail opening 111.

[0039] Optionally, the pusher 130 includes a pusher body 132, a second drive member 133, and a guide slide structure 134. The second drive member 133 is installed on the pusher body 132 and connected to the guide slide structure 134. A slide table 113 is provided inside the housing 110. The guide slide structure 134 is slidably engaged with the slide table 113. The second drive member 133 is used to drive the guide slide structure 134 to move when the pusher 130 extends out of the tail opening 111, so as to release the engagement state between the guide slide structure 134 and the slide table 113. Specifically, during the process of the first driving member 120 driving the pusher 130 to slide within the housing 110, the housing 110 can limit the pusher 130 through the cooperation of the slide table 113 and the guide structure 134, so as to ensure that the pusher 130 can only slide along the length direction of the housing 110, thereby improving the stability of the pusher 130 sliding within the housing 110 driven by the first driving member 120. During this process, the second driving member 133 is not activated, and the guide structure 134 and the slide table 113 maintain a sliding cooperation state. When the pusher 130 slides to the position of the tail opening 111, the second driving member 133 drives the guide structure 134 to move, thereby releasing the cooperation state between the guide structure 134 and the slide table 113, thus preventing the slide table 113 from interfering with the guide structure 134 when the pusher 130 rotates upward relative to the housing 110, and ensuring the reliability of the rotation of the pusher 130 relative to the housing 110.

[0040] The guide slide structure 134 includes a guide slide top plate 1341, a connecting plate 1342, and a guide slide bottom plate 1343. The guide slide top plate 1341 and the guide slide bottom plate 1343 are disposed opposite each other on both sides of the connecting plate 1342, and the guide slide top plate 1341, the connecting plate 1342, and the guide slide bottom plate 1343 together form a U-shape. The slide table 113 is slidably disposed between the guide slide top plate 1341 and the guide slide bottom plate 1343, and the slide table 113 can simultaneously guide and limit the guide slide top plate 1341, the connecting plate 1342, and the guide slide bottom plate 1343. Specifically, the pusher body 132 is fixedly connected to the connecting plate 1342 via the guide sliding top plate 1341, and the connecting plate 1342 is rotatably connected to the guide sliding bottom plate 1343. One end of the second driving member 133 is rotatably connected to the pusher body 132, and the other end is rotatably connected to the guide sliding bottom plate 1343. The second driving member 133 is used to drive the guide sliding bottom plate 1343 to rotate relative to the connecting plate 1342, so that the guide sliding bottom plate 1343 is separated from the slide table 113, thereby releasing the cooperation state between the guide sliding structure 134 and the slide table 113, so that the pusher 130 can smoothly rotate relative to the box 110 and extend out of the tail opening 111.

[0041] It should be noted that the top guide plate 1341 and the bottom guide plate 1343 are arranged parallel to each other and are both perpendicular to the connecting plate 1342. The second driving member 133 is used to drive the bottom guide plate 1343 to rotate until it is parallel to the connecting plate 1342. Specifically, when the guide structure 134 is in sliding engagement with the slide table 113, the top guide plate 1341 is located above the slide table 113, the connecting plate 1342 is located on the side of the slide table 113, and the bottom guide plate 1343 is located below the slide table 113. At this time, if the pusher 130 wants to rotate upward relative to the box 110, the slide table 113 will block the bottom guide plate 1343, thereby interfering with the rotation of the pusher 130. Therefore, in the self-cleaning trash can 100 of the present invention, before the pusher 130 rotates upward relative to the can body 110, the second driving member 133 drives the guide sliding bottom plate 1343 to rotate away from the guide sliding top plate 1341 until the guide sliding bottom plate 1343 is parallel to the connecting plate 1342. At this time, the guide sliding bottom plate 1343 is no longer located below the slide table 113, and the slide table 113 will not block the guide sliding bottom plate 1343, so that the first driving member 120 can drive the pusher 130 to rotate upward relative to the can body 110.

[0042] Optionally, there are two second driving members 133, two guide structures 134, and two sliding tables 113. The two sliding tables 113 are arranged opposite each other on both sides of the housing 110. Each second driving member 133 is connected to one guide structure 134, and each sliding table 113 is slidably engaged with one guide structure 134. The first driving member 120 is located in the middle between the two sliding tables 113. Specifically, the two guide structures 134 and the two sliding tables 113 work together to ensure the stability and safety of the pusher 130 sliding relative to the housing 110 under the drive of the first driving member 120.

[0043] The cleaning mechanism 140 includes a liquid storage tank 141, a water pump 142, and a water pipe 143. The water pump 142 is installed in the liquid storage tank 141 and connected to the water pipe 143. The water pipe 143 is equipped with a nozzle 144. The water pump 142 is used to draw cleaning liquid from the liquid storage tank 141 to the water pipe 143, and the nozzle 144 is used to spray the cleaning liquid into the tank body 110 to achieve the rinsing function of the tank body 110, which facilitates the flushing out of the front of the tank body 110 and improves the cleaning effect of the tank body 110.

[0044] In this embodiment, there are three storage tanks 141 and three water pumps 142. Each water pump 142 is installed in one storage tank 141. The first storage tank 141 is used to store clean water, the second storage tank 141 is used to store environmentally friendly biodegradable cleaning agent, and the third storage tank 141 is used to store disinfectant (such as diluted hypochlorous acid). By controlling the on / off state and flow rate of the three water pumps 142, the clean water, cleaning agent and disinfectant can be supplied in sequence, and the mixing ratio of clean water, cleaning agent and disinfectant can be quickly adjusted.

[0045] Optionally, the self-cleaning trash can 100 also includes a controller 160, a position sensor 170, and a vision sensor 180. The controller 160 is electrically connected to the position sensor 170, the vision sensor 180, and the water pump 142. The position sensor 170 is used to detect the movement position of the pusher 130, the vision sensor 180 is used to detect the amount of residual trash in the can body 110, and the controller 160 is used to control the water pump 142 to start when a flow gap 150 is formed between the pusher 130 and the bottom wall of the tail opening 111 and the amount of residual trash reaches a preset threshold, so as to clean the inside of the can body 110.

[0046] Furthermore, during the cleaning process of the cleaning mechanism 140 on the container 110, a pre-rinse is first performed, using clean water to perform a high-pressure rinse inside the container 110; then, a detergent is added, and a mixture of clean water and detergent is used to chemically clean the inside of the container 110; next, the system switches back to pure clean water to rinse the inside of the container 110; finally, a disinfectant is added, and a mixture of clean water and disinfectant is used to spray disinfectant inside the container 110, completing the cleaning process. Specifically, the controller 160 can determine the degree of dirtiness inside the container 110 based on the amount of residual waste detected by the vision sensor 180, thereby automatically adjusting the duration of the four steps: pre-rinse, chemical cleaning, rinsing, and disinfection. It also automatically adjusts the mixing ratio of clean water and detergent during the chemical cleaning process and the mixing ratio of clean water and disinfectant during the disinfection process, resulting in a high degree of automation and excellent cleaning effect.

[0047] It is worth noting that the self-cleaning trash can 100 has two modes: a trash collection mode and a self-cleaning mode. When the self-cleaning trash can 100 is in the trash collection mode, the first drive component 120 will only drive the pusher 130 to slide back and forth inside the can body 110, and will not drive the pusher 130 to extend out of the tail opening 111. The second drive component 133 will not be activated, and the cleaning mechanism 140 will not be activated. When the self-cleaning trash can 100 is in self-cleaning mode, the first drive component 120 will drive the pusher 130 to slide in the can body 110 towards the tail opening 111. The first drive component 120 will also drive the pusher 130 to extend out of the tail opening 111 and form a flow gap 150 with the bottom wall of the tail opening 111. The second drive component 133 will drive the guide sliding base plate 1343 to rotate, so as to release the cooperation between the guide sliding structure 134 and the slide table 113. The cleaning mechanism 140 will rinse the inside of the can body 110 so that the garbage and cleaning liquid at the front of the can body 110 can be discharged from the flow gap 150.

[0048] Optionally, the self-cleaning trash can 100 also includes a third drive unit 190 and a filler 200. The third drive unit 190 is installed on the can body 110 and connected to the filler 200, which is rotatably connected to the can body 110. The third drive unit 190 is used to drive the filler 200 to rotate relative to the can body 110 to open or close the tail opening 111. Specifically, during the process of the self-cleaning trash can 100 collecting trash, the filler 200 closes the tail opening 111. At this time, the filler 200 is used to put trash into the can body 110 and compress it to improve the trash collection efficiency. During the unloading process of the self-cleaning trash can 100, the third drive unit 190 drives the filler 200 to rotate to open the tail opening 111, so that the pusher 130 can push the trash in the can body 110 out of the tail opening 111.

[0049] Optionally, a front sealing plate 114 is provided on the side of the container 110 away from the tail opening 111. The front sealing plate 114 has a vent (not shown) for air passage when the pusher 130 slides relative to the container 110, so as to prevent the container 110 from deforming under air pressure when compressing or pushing out garbage.

[0050] In this embodiment, the first driving member 120, the second driving member 133, and the third driving member 190 are all hydraulic cylinders, but they are not limited to this. In other embodiments, the first driving member 120, the second driving member 133, and the third driving member 190 may also be electric cylinders or pneumatic cylinders.

[0051] The self-cleaning trash can 100 provided in this embodiment of the invention has a first driving member 120 installed inside the can body 110 and connected to a pusher 130. The pusher 130 is slidably disposed inside the can body 110. A cleaning mechanism 140 is installed inside the can body 110. The can body 110 has a tail opening 111. The first driving member 120 is used to drive the pusher 130 to slide towards the tail opening 111 so as to push the trash inside the can body 110 out of the tail opening 111. The first driving member 120 is also used to drive the pusher 130 to extend out of the tail opening 111 so that the pusher 130 is spaced apart from the bottom wall of the tail opening 111 and forms a flow gap 150. The cleaning mechanism 140 is used to clean the inside of the can body 110 so that residual trash and cleaning liquid are discharged from the flow gap 150. Compared with existing technologies, the self-cleaning garbage bin 100 provided by this invention, due to the adoption of a first driving component 120 connected to the pusher 130 and a cleaning mechanism 140 installed inside the bin body 110, can achieve self-cleaning of garbage at the front of the bin body 110 without the need for manual entry into the bin body 110. It has a high degree of mechanization, saves time and labor, has high cleaning efficiency, good cleaning effect, and high safety. This makes the garbage truck 10 easier to clean and achieves good cleaning results.
