[0056] The automatic garbage dumping assembly 5 also includes a lifting drive mechanism 56 , which is drivingly connected to the movable garbage bucket 3 .

[0057] The lifting drive mechanism 56 of the present invention may adopt the following structural design. Specifically, the lifting drive mechanism 56 includes a lower end rotating shaft 561 which is installed at the rear end of the frame 1 through a bearing seat and extends horizontally in the left-right direction;

[0058] A left shaft mounting portion 512 is disposed at the upper end of the left guide rail 51, and a right shaft mounting portion 522 is disposed at the upper end of the right guide rail 52. An upper shaft 562 is mounted between the left shaft mounting portion 512 and the right shaft mounting portion 522. The upper shaft 562 is located directly above the lower shaft 561 and extends horizontally in the left-right direction. The left end and the right end of the upper shaft 562 are respectively mounted on the left shaft mounting portion 512 and the right shaft mounting portion 522 on the corresponding side through bearings.

[0059] A lower sprocket 563 is clamped on the outer periphery of the lower rotating shaft 561, an upper sprocket 564 is clamped on the outer periphery of the upper rotating shaft 562, a transmission chain 565 is looped between the upper sprocket 564 and the lower sprocket 563, and the movable garbage bucket 3 is connected to the transmission chain 565;

[0060] The frame 1 is provided with a lifting drive motor 566 corresponding to the lower end rotating shaft 561, and the power output shaft of the lifting drive motor 566 is drivingly connected to the lower end rotating shaft 561. Preferably, the power output shaft of the lifting drive motor 566 is drivingly connected to the lower end rotating shaft 561 through a chain transmission mechanism.

[0061] It should be explained that the roller sweeping drive motor 24, the fan 42, the horizontal drive linear module 44, the vertical drive linear module 46, and the lifting drive motor 566 of the present invention are respectively electrically connected to the controller of the unmanned sweeper; when working, the controller controls the actions of the roller sweeping drive motor 24, the fan 42, the horizontal drive linear module 44, the vertical drive linear module 46, and the lifting drive motor 566 respectively.

[0062] like Figure 2 and Figure 4As shown, during the cleaning operation of the present invention, the front surface of the movable garbage hopper 3 is in sealing contact with the rear surface of the sweep cover 21, and the sweep cover garbage outlet 212 of the sweep cover 21 is aligned and connected with the garbage inlet 32 ​​of the movable garbage hopper 3; the lower surface of the movable exhaust hood 41 is in sealing contact with the upper surface of the movable garbage hopper 3, and the exhaust hood air inlet 412 of the movable exhaust hood 41 is aligned and connected with the garbage outlet of the movable garbage hopper 3. When the unmanned sweeper is moving and performing cleaning operations, the controller controls the roller sweeping drive motor 24 and the fan 42 to start, the roller sweeping drive motor 24 drives the roller sweeping shaft 22 to rotate, and the rotating roller sweeping shaft 22 drives the roller sweeping brush 23 to rotate synchronously, and the bristles of the roller sweeping brush 23 contact the ground and lift up the garbage on the ground; at the same time, the fan 42 draws air outward and generates a suction force, and the garbage lifted by the roller sweeping brush 23 under the action of the suction force enters the garbage storage chamber 31 through the roller sweeping cover garbage outlet 212 and the garbage hopper garbage inlet 32, and the airflow generated by the suction force passes through the garbage storage chamber 31, the garbage hopper garbage outlet 33, the exhaust hood air inlet 412, the exhaust chamber 411 and the exhaust hood air outlet 413 in sequence and is discharged; wherein, the filter 43 in the exhaust chamber 411 filters the above-mentioned airflow.

[0063] The movable garbage hopper 3 of the present invention is driven by the automatic garbage dumping component 5. When the garbage storage chamber 31 of the movable garbage hopper 3 is full of garbage and the garbage in the garbage storage chamber 31 needs to be dumped into the garbage bin, the unmanned sweeper moves to the garbage bin position, and the controller first controls the horizontal driving linear module 44 and the vertical driving linear module 46 to move, and the vertical driving module drives the vertical movable frame 47 and the movable exhaust hood 41 to move up and make the movable exhaust hood 41 separate from the movable garbage hopper 3, and then the horizontal driving linear module 44 drives the water pump 46 to move upward. The horizontal movable frame 45, the vertical drive linear module 46, the vertical movable frame 47, and the movable exhaust hood 41 move forward so that the movable exhaust hood 41 leaves the upper part of the movable garbage bucket 3; after the movable exhaust hood 41 moves away from the upper part of the movable garbage bucket 3, the controller controls the lifting drive motor 566 to start, and the lifting drive motor 566 drives the lower end rotating shaft 561 to rotate, and the rotating lower end rotating shaft 561 drives the upper end rotating shaft 561 through the chain transmission mechanism composed of the lower end sprocket 563, the upper end sprocket 564 and the transmission chain 565. The end rotating shaft 562 rotates synchronously, and in this process, the transmission chain 565 pulls the movable garbage bucket 3 to move upward; when the movable garbage bucket 3 is driven to rise by the lifting drive mechanism 56, the left rear end roller 542 moves along the left lifting guide groove 511 of the left guide rail 51, the right rear end roller 552 moves along the right lifting guide groove 521 of the right guide rail 52, the left front end roller 541 rolls upward along the front surface of the left guide rail 51, and the right front end roller 551 rolls along the front surface of the right guide rail 52 When the left front roller 541 and the left rear roller 542 enter the position of the guide rail arc 532 of the left guide rail 51 and the right front roller 551 and the right rear roller 552 enter the position of the guide rail arc 532 of the right guide rail 52, the movable garbage hopper 3 starts to flip, and the garbage hopper garbage outlet 33 of the movable garbage hopper 3 gradually flips downward. After the movable garbage hopper 3 flips into place, the garbage in the garbage storage chamber 31 is introduced into the garbage bin through the garbage hopper garbage outlet 33. After the garbage in the garbage storage chamber 31 is poured out, the lifting drive motor 566 rotates in the opposite direction, and the lifting drive mechanism 56 drives the movable garbage hopper 3 to move down and reset to the garbage collection position.

[0064] After the movable garbage bucket 3 pours out the garbage in the garbage storage chamber 31, the movable garbage bucket 3 and the movable exhaust hood 41 are reset, and the movable garbage bucket 3 is first moved down to the cleaning position under the driving action of the automatic garbage dumping component 5. In this process, the movable garbage bucket 3 is pressed down from above and the front surface of the movable garbage bucket 3 presses down the rear surface of the exhaust hood. Since the rear surface of the rolling sweep hood 21 is an inclined surface with the normal direction facing the upper rear and the front surface of the movable garbage bucket 3 is an inclined surface with the normal direction facing the lower front, the above-mentioned inclined surface design can ensure that the rear surface of the rolling sweep hood 21 is in contact and sealed with the front surface of the movable garbage bucket 3 when the movable garbage bucket 3 is pressed down, After the movable garbage hopper 3 moves down to the right position, the sweep cover garbage outlet 212 of the sweep cover 21 is aligned and connected with the garbage inlet 32 ​​of the movable garbage hopper 3; after the movable garbage hopper 3 moves down to the right position, the horizontal driving linear module 44 first drives the movable sweep cover 21 to move back to the top of the movable garbage hopper 3, and then the vertical driving linear module 46 drives the movable exhaust cover 41 to move down, and the movable exhaust cover 41 that moves down presses down the movable garbage hopper 3, that is, the lower surface of the movable exhaust cover 41 and the upper surface of the movable garbage hopper 3 are pressed and sealed, and at this time, the exhaust cover air inlet 412 of the movable exhaust cover 41 is aligned and connected with the garbage outlet 33 of the movable garbage hopper 3. The above structure enables the sweep cover 21, the movable garbage hopper 3, and the movable exhaust cover 41 to cooperate with each other and form a smooth sealing system.

[0065] In summary, it can be seen that through the above structural design, the present invention has the advantages of novel structural design and high degree of automation, and can achieve automatic sealing and automatic garbage disposal, that is, it can effectively improve the utilization rate of the unmanned sweeper.

[0066] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
