DETAILED DESCRIPTION

[0018] Embodiment 1

[0019] like Figure 1-Figure 3 As shown, a waste cleaning device proposed in this embodiment includes a cleaning frame 1 and a separation mechanism. The cleaning frame 1 is sequentially provided with two crushing rollers 7 rotating side by side, a guide plate 8, and a plurality of spray heads 6 evenly arranged on the inner side of the cleaning frame 1. The cleaning frame 1 is also sequentially connected with a water inlet pipe 5 and a mounting plate 4, and the water inlet pipe 5 is connected with the plurality of spray heads 6. The cleaning frame 1 is provided with wheels 3 and a slidably arranged handle 2, and the upper and lower sides of the handle 2 are in sliding contact with the cleaning frame 1.

[0020] The separation mechanism is arranged on the cleaning frame 1 and is located between the guide plate 8 and the plurality of spray heads 6. The separation mechanism includes a classification ring 9 arranged at the bottom of the guide plate 8, a screen cylinder 10 coaxially arranged at each end of the classification ring 9, a driving assembly drivingly connected to the two screen cylinders 10, and a conveying assembly connected to the two screen cylinders 10 in a one-to-one correspondence. The guide plate 8 gradually tilts downward from the four edges at the top to the center of the guide plate 8. The classification ring 9 has a guide block portion, and the guide block portion tilts from the center point of the guide block portion along the axis of the classification ring 9 to the bottom of the screen cylinder 10 on both sides. The diameter of the screen cylinder 10 gradually increases from one end surface that is in sliding contact with the classification ring 9 to the other end surface.

[0021] When this embodiment is used, the worker pulls out the handle 2 from the cleaning frame 1, moves the device to the vicinity of the waste that needs to be cleaned through the handle 2, connects the water pipe to the mounting plate 4, and the water flows along the water inlet pipe 5 to the multiple spray heads 6. Under the action of the multiple holes on the spray head 6, the water flow is diverted into multiple densely distributed small water flows, and the waste is poured from the top of the cleaning frame 1. The two crushing rollers 7 rotate relative to each other to crush the waste, and the guide plate 8 sends the waste to the classification ring 9. The classification ring 9 sends the waste to the two sieve drums 10. The driving component drives the two sieve drums 10 to rotate, and smaller fragments gradually fall to the bottom of the cleaning frame 1 in the sieve drum 10. Multiple small water flows are sprayed on the dust in the air, making the dust heavier and falling to the ground, thereby reducing the impact of dust on human health. The larger fragments will be sent to the conveying component by the sieve drum 10, and the conveying component will send the waste to the two crushing rollers 7 again to repeat the previous operation, thereby increasing the density of the waste.

[0022] Embodiment 2

[0023] like Figure 1-Figure 3 As shown, a waste cleaning device proposed in this embodiment, compared with embodiment one, in this embodiment, the screen drum 10 includes a screen drum main body 101 and a bevel gear portion 102, the bevel gear portion 102 is coaxially arranged on the outer peripheral surface of the screen drum main body 101, and the driving assembly includes a motor a11 arranged on the cleaning frame 1, a driving rod connected to the output end of the motor a11, and a bevel gear 12 coaxially arranged on the driving rod, and the bevel gear 12 is meshingly connected with the two bevel gear portions 102.

[0024] In this embodiment, when screening waste, the motor a11 drives the driving rod to rotate, the driving rod drives the bevel gear 12 to rotate, and the bevel gear 12 drives the two bevel gear parts 102 to rotate, thereby preventing the fragments from getting stuck with each other in the screen drum 10 and accumulating in the screen drum 10, and allowing larger fragments to always remain in motion and move to the conveying component, thereby improving the screening effect of the device.

[0025] Embodiment 3

[0027] In this embodiment, after the waste falls from the screen drum 10 onto the conveying blades in the conveying frame 13, the conveying blades will cause multiple wastes to squeeze each other during rotation, allowing the fragments to move one by one to the top of the conveying frame 13, and fall from the output channel 131 to the guide groove. The waste moves to between the two crushing rollers 7 on the guide groove under the action of its own gravity for secondary crushing, thereby increasing the density of the crushed waste, reducing the number of times workers carry the crushed waste away, and reducing the workers' work intensity.

[0028] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
