[0034] A magnetic impurity adsorption and cleaning mechanism, which is fixedly arranged on the top of the power mechanism and is used to clean magnetic impurities on the road surface;

[0035] A garbage cleaning mechanism, which is fixedly arranged on the top of the power mechanism and is used to clean up garbage on the road surface;

[0036] A negative pressure dust suction mechanism, which is fixedly arranged on the top of the power mechanism and is used to clean the dust on the road surface;

[0037] A spraying mechanism, which is fixedly arranged on the top of the power mechanism and is used for spraying water on the road surface for maintenance;

[0038] The magnetic impurity adsorption and cleaning mechanism, the garbage cleaning mechanism, the negative pressure dust suction mechanism and the spraying mechanism are arranged in sequence along the length direction of the power mechanism.

[0039] A further optimized solution is provided, wherein the magnetic impurity adsorption and cleaning mechanism comprises a first collection box 4, the bottom end of the first collection box 4 is fixedly connected to the top end of the power mechanism, the top end of the first collection box 4 is rotatably connected to a first collection cover 5, the top end of the inner wall of the first collection box 4 is fixedly connected to a second motor 18, the output shaft of the second motor 18 is fixedly connected to one end of a horizontally arranged lead screw 19, the other end of the lead screw 19 is rotatably connected to the inner wall of the first collection box 4, the outer wall of the lead screw 19 is threadedly connected to one end of a horizontally arranged sliding beam 20, the sliding beam 20 is perpendicular to the lead screw 19, and the sliding beam 20 is also threadedly connected to the outer wall of the lead screw 19. One end is slidably connected to a guide rod 21, and both ends of the guide rod 21 are fixedly connected to the inner wall of the first collecting box 4, the guide rod 21 is parallel to the screw 19 and is horizontally arranged, and the two ends of the bottom of the sliding beam 20 are fixedly connected to the top of the vertically arranged second telescopic rod 22, and the bottom ends of the two second telescopic rods 22 are commonly fixedly connected to the first electromagnet 24, and the first collecting plate 23 is fixedly connected to the bottom of the inner wall of the first collecting box 4, the first collecting plate 23 and the inner wall of the first collecting box 4 form a first collecting space, and a magnetic impurity adsorption part is correspondingly arranged below the first electromagnet 24.

[0040] A further optimized solution is that the magnetic impurity adsorption part includes a third motor 25, which is fixedly embedded in the power mechanism, and the output end of the third motor 25 is fixedly connected to one end of a horizontally arranged rotating shaft 26, and the other end of the rotating shaft 26 is rotatably connected to the power mechanism, and the top and bottom ends of the rotating shaft 26 are respectively fixedly connected to one end of a plurality of equally spaced connecting rods 27, and the other ends of the plurality of connecting rods 27 located at the bottom end of the rotating shaft 26 are commonly fixedly connected to a second electromagnet 28, and the other ends of the plurality of connecting rods 27 located at the top end of the rotating shaft 26 are commonly fixedly connected to another second electromagnet 28, and the side of the second electromagnet 28 away from the connecting rod 27 is a concave surface, and the second electromagnet 28 is located below the first electromagnet 24.

[0041] When the road surface is maintained, as the device continues to move forward, one of the two second electromagnets 28 located at the bottom is energized to make it magnetic. As the device continues to move forward, the second electromagnet 28 with magnetism can adsorb magnetic objects on the road surface. After it adsorbs a certain number of magnetic objects, the third motor 25 drives the rotating shaft 26 to rotate, so that the second electromagnet 28 adsorbing the magnetic objects rotates from directly below to directly above. After rotating in place, it is powered off to make it lose its magnetism. Due to the concave shape of the side of the second electromagnet 28, after it loses its magnetism, the magnetic objects will not fall from its sides. The first electromagnet 24 is powered on to generate magnetism, which attracts the magnetic object. The second telescopic rod 22 is shortened to drive the first electromagnet 24 and the magnetic object to rise to the highest end. The second motor 18 drives the lead screw 19 to rotate and move the first electromagnet 24 and the magnetic object horizontally to the top of the first collecting space. The first electromagnet 24 is powered off, and the magnetic object falls into the first collecting space. The first electromagnet 24 is reset, and when the second electromagnet 28 with the magnetic object adsorbed rotates to the top, the other second electromagnet 28 without the magnetic object adsorbed rotates to the bottom and is powered on to generate magnetism to start adsorbing the magnetic object.

[0042] A further optimized solution is that the garbage cleaning mechanism includes a second collecting box 6, the bottom end of the second collecting box 6 is fixedly connected to the top of the power mechanism, the top of the second collecting box 6 is rotatably connected to a second collecting cover 7, the top of the outer wall of the second collecting box 6 is fixedly connected to a first motor 8, the output shaft of the first motor 8 is fixedly connected to one end of a horizontally arranged active roller 30, the active roller 30 is rotatably arranged inside the second collecting box 6, the other end of the active roller 30 is rotatably connected to the inner wall of the second collecting box 6, a driven roller 31 is arranged below the side of the active roller 30, the driven roller 31 is horizontally arranged and the two ends are respectively rotatably connected to the inner wall of the second collecting box 6, the outer side of the active roller 30 A conveyor belt 32 is wound around the outer side of the driven roller 31, and a plurality of baffles 33 arranged at equal intervals are fixedly connected to the outer wall of the conveyor belt 32. A special-shaped plate 35 is arranged on one side below the driven roller 31, and the top of the special-shaped plate 35 is fixedly connected to the power mechanism. A straight plate 36 is arranged on the other side below the driven roller 31, and the top of the straight plate 36 is fixedly connected to the power mechanism. A garbage cleaning part is arranged below the side of the straight plate 36 away from the special-shaped plate 35, and the garbage cleaning part corresponds to the bottom of the special-shaped plate 35. A second collecting plate 34 is fixedly connected to the bottom of the inner wall of the second collecting box 6, and the second collecting plate 34 and the inner wall of the second collecting box 6 form a second collecting space.

[0043] A further optimized solution is that the garbage cleaning unit includes a fifth motor 37, which is fixedly connected to the bottom end of the power mechanism, and the output shaft of the fifth motor 37 is fixedly connected to a driving gear 38. The bottom end of the power mechanism is fixedly connected to the top ends of two vertically arranged connecting blocks 42, and the two connecting blocks 42 are arranged at intervals. A rotating roller 40 is rotatably connected between the two connecting blocks 42, and a plurality of cleaning plates 41 are fixedly connected to the outer side wall of the rotating roller 40, and the plurality of cleaning plates 41 are equidistantly arranged along the circumferential direction of the outer side wall of the rotating roller 40. The end of the rotating roller 40 close to the fifth motor 37 is fixedly connected to a driven gear 39, and the driven gear 39 is in transmission meshing engagement with the driving gear 38.

[0044] As the device moves forward, the fifth motor 37 works to drive the rotating roller 40 and the cleaning plate 41 to rotate continuously. The rotation direction of the two is opposite to the forward direction of the device. During the rotation, the garbage on the road surface is pushed between the special-shaped plate 35 and the straight plate 36. As the garbage is continuously pushed in, the garbage eventually rises to the position of the driven roller 31. The active roller 30 and the driven roller 31 drive the conveyor belt 32 to rotate continuously. During the rotation, the garbage is transported to the position of the active roller 30 through the baffle 33, and then falls into the second collection space.

[0045] A further optimized solution is that the negative pressure dust suction mechanism includes a third collecting box 9, the bottom end of the third collecting box 9 is fixedly connected to the top of the power mechanism, the top of the third collecting box 9 is rotatably connected to a third collecting cover 10, the top of the third collecting cover 10 is fixedly connected to a negative pressure pump 11, the air inlet end of the negative pressure pump 11 is fixedly connected to the inside of the third collecting box 9, and a dust suction box 45 is correspondingly arranged below the third collecting box 9, the large mouth of the dust suction box 45 faces downward, and the top of the dust suction box 45 is fixedly connected to one end of a plurality of equally spaced connecting bends 46, and the other end of the connecting bends 46 faces the inner bottom wall of the third collecting box 9, and the top of the inner wall of the third collecting box 9 is detachably connected to a filter part.

[0047] As the device continues to move forward, after the magnetic objects and garbage on the road surface are cleaned up, the negative pressure pump 11 works to form a negative pressure in the third collecting box 9 and the dust box 45. The negative pressure sucks the dust on the road surface into the dust box 45 and enters the third collecting box 9 through the connecting elbow 46. The curved design of the connecting elbow 46 can reduce the amount of dust inside the third collecting box 9. The filter net 44 can further block the dust to prevent the dust from entering the negative pressure pump 11 and causing operational failures.

[0048] A further optimized solution is that the spraying mechanism includes a water tank 12, the bottom end of the water tank 12 is fixedly connected to the top of the power mechanism, the top wall of the water tank 12 is fixedly connected to the bottom end of a vertically arranged water injection pipe 13, a water pump is arranged on the bottom wall of the water tank 12, and the water outlet end of the water pump is fixedly connected to a telescopic sprinkler part, the telescopic sprinkler part is located on the side of the water tank 12 away from the negative pressure dust suction mechanism, and the two ends of the telescopic sprinkler part are fixedly connected to the two opposite outer walls of the water tank 12.

[0050] After the garbage and dust on the road surface are cleaned, the water pump works to pump the water in the water tank 12 into the water outlet pipe 15, and further sprays it out through the nozzle 16 to water the road surface for maintenance. After the watering is completed, the telescopic end of the first telescopic rod 14 retracts, driving the water outlet pipe 15 and the nozzle 16 to be recovered into the power mechanism, which plays a certain protective function for the water outlet pipe 15 and the nozzle 16.

[0051] A further optimized solution is that the power mechanism includes a vehicle body 1, a magnetic impurity adsorption and cleaning mechanism, a garbage cleaning mechanism, a negative pressure dust suction mechanism, and a spraying mechanism are fixedly connected to the top of the vehicle body 1 and are arranged along the length direction of the vehicle body 1, a vehicle head 2 is fixedly connected to the top of the vehicle body 1, and the vehicle head 2 is located on the side of the magnetic impurity adsorption and cleaning mechanism away from the garbage cleaning mechanism, and wheels 3 are respectively arranged at both ends of the bottom of the vehicle body 1.
