The carrier plate 3 is arranged at the front end of the cart 1 and a connecting pipe 31 is arranged at the lower end thereof, the connecting pipe 31 runs through the body of the carrier plate 3, the air suction hood 5 is installed at the end of the connecting pipe 31, the output end of the vacuum cleaner 2 is connected to the connecting pipe 31 through the air duct 21, and the rotating disc 4 is rotatably connected to the outside of the connecting pipe 31. Specifically, an annular groove 311 is coaxially provided at the outer wall of the connecting pipe 31, and a through hole 41 is provided at the center of the rotating disc 4. The rotating disc 4 is rotatably connected to the annular groove 311 through the through hole 41, so as to realize the rotatable connection between the rotating disc 4 and the connecting pipe 31;

[0028] The lower end of the rotating disk 4 is provided with a plurality of cleaning members 6 distributed in an annular manner, and the plurality of cleaning members 6 are all twisted at a set angle, and the twisting angles and twisting directions of the plurality of broom heads 62 are the same (e.g. Figure 4), the suction hood 5 is located between a plurality of cleaning members 6; the carrier plate 3 is provided with a power drive mechanism 7 for driving the rotating disk 4 to rotate, and the trolley 1 is provided with a lifting mechanism 8 for driving the carrier plate 3 to rise and fall.

[0029] In this embodiment, the lifting mechanism 8 drives the carrier plate 3 to rise and fall, thereby realizing the height adjustment of the plurality of cleaning members 6, so that the cleaning members 6 can contact the ground, and then the power drive mechanism 7 drives the rotating disk 4 to rotate, so as to realize the rotation of the cleaning members 6, and cooperate with the set torsion angle of the cleaning members 6, so that the plurality of cleaning members 6 can gather the fallen leaves on the ground when rotating (that is, if the cleaning members 6 are twisted counterclockwise, the rotating disk 4 also rotates counterclockwise), and the fallen leaves are gathered in the middle of the plurality of cleaning members 6, that is, directly below the suction hood 5, so that it is convenient for the vacuum cleaner 2 to suck away the fallen leaves through the suction hood 5 and the air duct 21, and complete the collection of the fallen leaves; in the process of the staff pushing the cart 1 to move, the fallen leaves in different areas can be collected.

[0030] Specifically, the cleaning member 6 is configured as a first rod member 61 and a broom head 62 threadedly connected to the end of the first rod member 61, and the first rod member 61 is longitudinally installed on the rotating disk 4; the end of the first rod member 61 is provided with a thread, and the broom head 62 is provided with an internal threaded sleeve 621 that cooperates with the thread at the end of the first rod member 61, so as to realize the threaded connection between the broom head 62 and the first rod member 61. The broom head 62 can be easily disassembled and replaced after long-term use and wear.

[0031] In another embodiment, if Figure 2 and Figure 4 As shown, a plurality of second rods 42 are distributed in an annular manner at the lower end of the rotating disk 4, a plurality of first rods 61 and a plurality of second rods 42 are distributed crosswise, a bamboo rake 43 is threadedly connected to the lower end of each second rod 42, and the connection mode between the second rod 42 and the bamboo rake 43 is consistent with the connection mode between the broom head 62 and the first rod 61, and the torsion angle and torsion direction of the bamboo rake 43 are consistent with those of the broom head 62; a plurality of claws 431 on the bamboo rake 43 are all arranged in an "L" shape, and the overall angle of the claws 431 is inclined outward (such as Figure 7 ).

[0032] When collecting fallen leaves, the broom head 62 alone cannot effectively sweep away the fallen leaves, or after a rainy day, the fallen leaves are not completely dry and will stick to the ground, and the broom head 62 alone cannot effectively sweep them away. Therefore, in this embodiment, the bamboo claws 431 are arranged to be inclined outward, so that they have a certain toughness and elasticity to resist the ground. As the multiple bamboo rakes 43 rotate, the fallen leaves on the ground can be driven to move together, and then the broom head 62 can be used to gather the fallen leaves just below the suction hood 5, which is convenient for collecting the fallen leaves. It should be noted that when collecting the fallen leaves on the lawn, the bamboo rakes 43 cannot be prevented from damaging the lawn, and can be disassembled and replaced with the broom head 62.

The outer ring gear 71 is coaxially fixedly connected to the rotating disk 4, and the gear 72 is rotatably connected to the carrier plate 3 through the gear 72 shaft. The gear 72 is meshed with the outer ring gear 71, and the rotation drive source 73 is fixedly connected to the bottom of the carrier plate 3 through a bracket 75. The output shaft of the rotation drive source 73 is coaxially fixedly connected to the gear 72; the rotation of the rotation drive source 73 can drive the gear 72 to rotate, and the outer ring gear 71 can drive the rotating disk 4 to rotate on the connecting pipe 31, so that multiple broom heads 62 rotate to sweep and collect fallen leaves on the ground.

[0034] Specifically, the lifting mechanism 8 includes a hydraulic cylinder, a frame and a sliding plate. The frame is installed on the cart 1, the sliding plate is arranged horizontally and is slidably connected to the frame in the longitudinal direction, the hydraulic cylinder is longitudinally installed on the cart 1, and the output end of the hydraulic cylinder is fixedly connected to the sliding plate through a connecting plate; the height of the broom head 62 and the bamboo rake 43 can be controlled by the operation of the hydraulic cylinder to ensure that the broom head 62 or the bamboo rake 43 can effectively clean the fallen leaves on the ground.

[0035] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
