[0076] A garbage can cleaning system provided by an embodiment of the present invention can realize efficient transmission cleaning of multiple garbage cans 7 through transmission by a circulating garbage can 7, washing and spraying under and on the sides of the inverted garbage can 7, and rolling brushing on the sides and inner cavity of the garbage can 7, thereby effectively solving the problems of low cleaning efficiency and incomplete cleaning of the garbage can cleaning system in the prior art.

[0077] Specifically, by setting the circulating transmission mechanism 1, the circulating transmission of the hanger 101 on the circulating track 102 can be effectively realized; by setting the hanger 101, the trash can 7 can be lifted upside down, so that water is not easy to accumulate in the trash can 7 and dirt is easy to fall off; by setting the transmission mechanism 2, the trash can 7 can be supported during brushing and can maintain synchronous operation with the trash can 7; at the same time, at least two parallel belts are set in the transmission mechanism 2, and there is a first gap 204 between the two belts, so that the first spraying mechanism 3 can be set below the belt and can spray into the inner cavity of the trash can 7;

[0078] By setting the first roller brush mechanism 4, the outer wall of the trash can 7 can be roller brushed; at the same time, by setting the second spray mechanism 5, the roller brush part can be rinsed, so that the outer wall of the trash can 7 is cleaned more thoroughly;

[0079] By setting the second roller brush mechanism 6, the inner cavity of the trash can 7 can be roller brushed. At the same time, by setting the lifting mechanism 602, the second roller brush wheel 601 can make up and down reciprocating motion in the first gap 204, that is, when a trash can 7 is directly above the second roller brush mechanism 6, the second roller brush wheel 601 moves upward under the drive of the lifting mechanism 602, and enters the inner cavity of the trash can 7 to roller brush; when the roller brushing is finished, it shrinks to the bottom of the conveying mechanism 2, thereby allowing the trash can 7 to continue to pass.

[0080] According to the garbage can cleaning system provided by the embodiment of the present invention, Figure 4 As shown, a plurality of wedge-shaped clamping blocks 202 are sequentially arranged on the surface of the conveyor belt 201 along the length direction.

[0081] In this embodiment, the conveyor belt 201 can be a rubber belt, and its surface is raised with multiple wedge-shaped clamping blocks 202 arranged along the length direction. The wedge-shaped clamping blocks 202 can also be made of rubber. Their function is to position and limit the trash can 7 pressed against the surface of the conveyor belt 201, and the vertical surfaces of the wedge-shaped clamping blocks 202 are all facing the direction of movement of the conveyor belt 201, that is, the inclined surfaces are all away from the movement direction of the conveyor belt 201; when the trash can 7 is pressed down to the surface of the conveyor belt 201, its opening edge is just stuck between two adjacent wedge-shaped clamping blocks 202; and the vertical surface of the wedge-shaped clamping blocks 202 gives a thrust to the inner wall of the trash can 7.

[0082] According to the garbage can cleaning system provided by the embodiment of the present invention, Figure 4 As shown, the conveyor belt 201 is provided with a plurality of through holes 203 in sequence along the length direction.

[0083] In this embodiment, the conveyor belt 201 is provided with a plurality of long strip through holes 203 in sequence along the length direction, and its main function is to drain the water falling on the surface of the conveyor belt 201, while reducing the weight of the conveyor belt 201 itself, making it more resilient.

[0084] According to the garbage can cleaning system provided by the embodiment of the present invention, Figures 6 to 8 As shown, the circulating track 102 includes: a track body 1021, a chain plate 1022, a driving sprocket 1024 and a passive sprocket 1025, wherein the track body 1021 is provided with a track groove, and the track body 1021 has at least two parallel arranged; the chain plate 1022 has a plurality of chains, which are respectively arranged in the track groove; the driving sprocket 1024 is rotatably arranged in the track groove; the passive sprocket 1025 is rotatably arranged in the track groove; wherein the chain plate 1022 is respectively engaged with the driving sprocket 1024 and the passive sprocket 1025; the hanger 101 is fixed to the upper surface of the chain plate 1022.

[0085] In this embodiment, the track body 1021 is provided with two parallel tracks, and the track body 1021 is provided in a closed loop, so that the multiple hangers 101 can be moved in a loop. The operator only needs to install the trash can 7 at one end of the track and remove the trash can 7 at the other end of the track, thereby improving the work efficiency.

[0086] The driving sprocket 1024 and the passive sprocket 1025 are both rotatably installed in the track groove, and three sets of passive sprockets 1025 are equidistantly installed between two adjacent sets of driving sprockets 1024. The driving sprocket 1024 is externally connected to a sprocket motor 1023, which is a reduction servo motor and can be synchronously rotated and controlled by a PLC;

[0087] Accordingly, the chain plate 1022 is composed of a plurality of chain plate 1022 units installed, with gaps between them, and can be elastically deformed so as to adapt to the arc structure of the circulating track 102; each chain plate 1022 unit is provided with four sprocket engaging holes, which can be engaged with the driving sprocket 1024 and the passive sprocket 1025, so that the chain plate 1022 moves when the driving sprocket 1024 rotates. The support leg 1014 of the hanger 101 is rotatably fixed on a chain plate 1022 unit to adapt to the arc bending.

[0088] According to the garbage can cleaning system provided by the embodiment of the present invention, Fig. 9 As shown, the hanger 101 includes: a crossbeam 1011, an electric telescopic rod 1012 and a suction cup 1013, wherein support feet 1014 are respectively provided at both ends of the crossbeam 1011, the crossbeam 1011 spans multiple track bodies 1021, and the support feet 1014 are fixedly connected to the chain plate 1022; one end of the electric telescopic rod 1012 is fixedly connected to the crossbeam 1011 and is arranged downwardly perpendicular to the crossbeam 1011; the suction cup 1013 is fixedly connected to the other end of the electric telescopic rod 1012.

[0089] In this embodiment, the crossbeam 1011 of the hanger 101 spans across the two track bodies 1021 and is fixed on the chain plate 1022 by the support foot 1014; when the chain plate 1022 moves, the hanger 101 moves accordingly, and the distances between multiple hangers 101 are equal; the electric telescopic rod 1012 is a thrust-sensing electric push rod, which has a stress sensor integrated inside. When the stress sensor senses that the thrust reaches a preset value, the controller controls the electric telescopic rod 1012 to stop pushing. This is to ensure that the trash can 7 has a certain downward pressure when it is pressed against the conveyor belt 201, but at the same time, the downward pressure is not too large, which causes the conveyor belt 201 to deform. It can also ensure the stability of the trash can 7 during the cleaning process and prevent it from shaking.

[0090] The suction cup 1013 can be an electric suction cup 1013 or a rubber suction cup 1013, which can be flexibly selected during manufacturing.

[0091] According to the garbage can cleaning system provided by the embodiment of the present invention, Fig.10 and Fig.11 As shown, the first spray mechanism 3 also includes: a washing tank 301, a first pipe 302 and a first liquid pump 303, wherein the washing tank 301 is arranged below the first gap 204; one end of the first pipe 302 is connected to the washing tank 301, and the other end is connected to the first nozzle; the first liquid pump 303 is arranged in the first pipe 302, and is used to pump the washing liquid in the washing tank 301 to the first nozzle.

[0092] In this embodiment, the washing pool 301 is arranged below the first spray mechanism 3, and is also arranged below the entire garbage can cleaning system, that is, a trench is dug underground; one end of the first pipe 302 is connected to the washing pool 301, and the other end is connected to the first nozzle; in this way, the washing liquid can be recovered, because the garbage can 7 is inverted, and the water stains flushed inside the garbage can 7 will pass through the filter net above the washing pool 301, and after blocking large pieces of residual garbage, the washing liquid flows into the washing pool 301;

[0093] like Fig.11 As shown, another ground trough is opened at a position adjacent to the washing tank 301, serving as the cleaning tank 304, so a second pipe 305 is connected to the cleaning tank 304, a second liquid pump 306 is installed on the second pipe 305, and a plurality of first nozzles are also provided at the other end of the second pipe 305 for spraying and cleaning the washed garbage can 7; similarly, the cleaned liquid passes through the filter net into the cleaning tank 304; in this way, the garbage can 7 can be thoroughly cleaned.

[0094] According to the garbage can cleaning system provided by the embodiment of the present invention, Fig.12 As shown, the first roller brush mechanism 4 also includes: a roller brush frame 402 and a first driving mechanism, wherein the roller brush frame 402 is arranged on both sides of the conveying mechanism 2, and the first roller brush wheel 401 is rotatably arranged on the roller brush frame 402; the first driving mechanism is connected to the first roller brush wheel 401, and is used to drive the first roller brush wheel 401 to rotate.

[0095] In this embodiment, the roller brush frame 402 is preferably a hollow wall structure, which is respectively installed on both sides of the conveying mechanism 2, and has a window thereon, and the first roller brush wheel 401 is rotatably installed in the window. There is a gap between the two first roller brush wheels 401 arranged opposite to each other, which can allow the trash can 7 to pass through, but the gap is smaller than the diameter of the trash can 7, so the bristles of the first roller brush wheel 401 are flexible;

[0096] The first driving mechanism may be a combination of a first motor and a first gear transmission mechanism; the output end of the first gear transmission mechanism is connected to the first roller brush wheel 401; and the two first roller brush wheels 401 arranged opposite to each other rotate synchronously in opposite directions.

[0097] In this way, the physical cleaning of the outer wall of the trash can 7 can be achieved.

[0098] Since the distance between the two hangers 101 is constant and both are fixed to the chain plate 1022, when the trash can 7 moves between the two first roller brush wheels 401, the PLC controls the chain plate 1022 to stop running. At this time, the previous trash can 7 is just above the second roller brush mechanism 6. Then the second roller brush mechanism 6 is started and the second roller brush wheel 601 is extended into the inner cavity of the trash can 7 through the lifting mechanism 602. When the roller brushing is finished, the lifting mechanism 602 descends and retracts the second roller brush wheel 601 to the bottom of the conveying mechanism 2. At this time, the PLC controls the chain plate 1022 to continue running.

[0099] According to the garbage can cleaning system provided by the embodiment of the present invention, Fig.12 As shown, the second spray mechanism 5 also includes: a main pipeline 501 and a branch pipeline, wherein one end of the main pipeline 501 is connected to the first pipeline 302; there are multiple branch pipelines, one end of which is connected to the other end of the main pipeline 501, and the other end of the branch pipeline is connected to the second nozzle 502.

[0100] In this embodiment, one end of the main pipeline 501 is connected to the first pipeline 302, and the other end is branched into multiple branch pipelines, and a second nozzle 502 is installed on the end of each branch pipeline; the nozzles of the second nozzle 502 are all directed toward the contact surface between the first roller brush wheel 401 and the trash can 7, that is, brushing and flushing are achieved.
