[0081] Embodiment 2:

[0082] Those skilled in the art may understand this embodiment as a more specific description of Embodiment 1.

[0083] like Figures 1 to 7 As shown, this embodiment provides a garbage cleaning device integrating collection and discharge, including: a collection box 1, a door lock mechanism 2, a conveyor belt conveying mechanism 3, a conveying protection mechanism 4 and a conveying drive mechanism 5.

[0084] The collection box 1 is mainly formed by welding steel plates, including a box front cover 11, a box side bottom plate 12, a box top plate 13, a box rear frame 14 and a discharge door 17. The box side bottom plate 12 is a V-shaped folding plate structure, and the folding plate side plate angle is up to 45°, which can meet the self-dumping angle of urban garbage. A U-shaped guide groove 15 is provided at the lower part of the box side bottom plate 12 for inserting and installing the conveying mechanism.

[0085] The door lock mechanism 2 includes an installation hinge 21, a flip electric push rod 22, a locking electric push rod 23, a locking hook pawl 24 and a locking seat 25. The door lock mechanism 2 is located at the rear of the collection box 1 and is connected to the collection box 1 through the upper hinge 21. The flipping action of opening and closing the discharge door 17 is performed by the flipping electric push rod 22. A locking hook pawl 24 is arranged at the front of the locking electric push rod 23. When the discharge door 17 is closed, the locking electric push rod 23 drives the locking hook pawl 24 to hook the locking seat 25 on the discharge door 17, so that the discharge door 17 is tightly combined with the sealing strip 26 at the rear of the collection box 1 to ensure the sealing of the box.

[0086] The conveyor belt conveying mechanism 3 is located at the bottom of the collection box 1, and includes a conveying frame 31, a driving shaft 32, a driven shaft 33, a roller 34, a frame connecting rib 35, and a conveying belt 36. The conveying frame 31 is a special frame, with a bevel block 37 at the front end for inserting and limiting the conveying mechanism, a tension adjustment hole 38 at the side, which can adjust the tightness of the conveying belt 36, and a disassembly and lifting hole 39 at the rear end for quick disassembly and maintenance of the conveying mechanism. The cone angles on both sides of the central cylinder of the driving shaft 32 and the driven shaft 33 are set to prevent the conveying belt 36 from sliding sideways during rolling.

[0087] The conveying protection structure 4 includes a protective rubber 41, a limit block 42, a fixed seat 43 and a rotating shaft protective rubber pad 6. The protective rubber 41 plays a role in guiding garbage and improving the neatness of garbage cleaning. The limit block 42 cooperates with the inclined stopper 37 at the front of the conveyor belt conveying mechanism 3, and the fixed seat 43 cooperates with the disassembly and assembly lifting hole 39 to limit the front and rear positions of the conveyor belt and provide protection. The rotating shaft protective rubber pad 6 can prevent small garbage from entering the rotating area of ​​the conveyor belt and improve its service life.

[0088] The conveying drive mechanism 5 includes a driving cover 51, a driving motor 52, a cover shield 53, an isolation cover 54, a first magnetic coupling and a second magnetic coupling 55. The driving cover 51 provides a fixed installation position for the driving motor 52, and at the same time forms an independent isolation space with the cover shield 53 to protect the first magnetic coupling and the second magnetic coupling 55, preventing the coupling surface from contacting the garbage inside the box, adsorbing iron filings, etc. The isolation cover 54 uses its own thickness to isolate the first magnetic coupling and the second magnetic coupling 55 to prevent direct contact. There are two magnetic couplings, one of which is fixed to the output shaft end of the driving motor 52, that is, the first magnetic coupling, and the other is fixed to one end of the driving shaft 32, that is, the first magnetic coupling 55, to achieve power transmission without fixed contact. When the conveyor belt conveying mechanism 3 needs to be dismantled and maintained, manpower can easily stagger the connection state of the first magnetic coupling and the second magnetic coupling 55 in the horizontal direction.

[0089] The installation method of the conveyor belt conveying mechanism 3 is as follows: the second magnetic coupling 55 is first installed at the input end of the driving shaft 32, and then the conveyor belt conveying mechanism 3 is inserted from the rear of the collection box 1. The front of the conveyor belt conveying mechanism 3 needs to be inserted into the protective rubber 41, and the input end of the driving shaft 32 at the rear is inserted from the U-shaped guide groove 15, and the second magnetic coupling 55 enters the inside of the driving cover 51. Adjust the installation position so that the inclined surface block 37 at the front of the conveyor belt conveying mechanism 3 is in close contact with the limit block 42, so that the axis of the first magnetic coupling and the second magnetic coupling 55 coincide. Finally, squeeze the conveying frame 31 through the fixing seat 43 and fasten it to the inside of the collection box 1 with a bolt group.

[0090] Quick disassembly and maintenance method of the conveyor belt conveying mechanism 3: According to the installation and fixing method of the conveyor belt conveying mechanism 3, it is only necessary to remove the fixing seat 43 at the tail, and use the disassembly hook to hook the disassembly and assembly lifting hole 39 set at the tail of the conveying frame 31, and then the entire conveying mechanism can be pulled out horizontally.

[0091] Garbage collection and discharge process: The feed port 18 of the collection box 1 is located at the front of the box, and the discharge port 16 is located at the rear of the box. In the initial state, the discharge door 17 is closed and locked, and the conveyor belt conveying mechanism 3 is in a shutdown state. Garbage enters the collection box 1 from the feed port 18. During the feeding period, the conveyor belt conveying mechanism 3 can be opened to transport and stack the garbage to the discharge door 17, making full use of the internal space of the box to fill the garbage. When the garbage bin is dumping, the locking electric push rod 23 drives the locking hook 24 to unlock the discharge door 17, and the discharge door 17 is opened and flipped to the highest position by flipping the electric push rod 22. Once the conveyor belt conveying mechanism 3 is started, the garbage in the box can be transported and discharged.

[0092] The utility model provides a conveyor belt conveying mechanism at the bottom of the collection box body to send out the garbage, which has the advantages of not being easily stuck and being highly efficient in unloading. At the same time, a conveying protection mechanism is provided to play a good protective role on the conveyor belt conveying mechanism.
