[0026] A collection box 6 is fixedly installed at the bottom of vehicle body 1, and the box opening of the collection box 6 faces the two cleaning rollers 4 in the horizontal direction, for collecting foreign matter.

[0027] The collecting box 6 is fixedly arranged with two horizontal support rods on the end part facing the sweeping roller 4, and the box opening is between the two support rods, which are symmetrical relative to the box opening.

[0028] An inclined movable plate 10 is arranged between the two support rods, which is inclined to the runway and faces the box opening. The end part of the movable plate 10 close to the box opening extends into the box opening, and the end part of the movable plate 10 is the high end. The end part of the movable plate 10 away from the box opening is the low end.

[0029] Two mounting grooves are arranged on the opposite end faces of the two support rods in the inclined direction of the movable plate 10, and the groove openings of the two mounting grooves are opposite. A long strip-shaped sliding block is slidingly arranged in each of the two mounting grooves, and the movable plate 10 is located between the two sliding blocks and is fixedly connected with the two sliding blocks.

[0030] The movable plate 10 is drivingly connected with the two rotating shafts 8 through a transmission member, and the transmission member is used to drive the movable plate 10 to slide in the inclined direction to approach or move away from the runway.

[0031] Specifically, the transmission member includes a connecting rod 5. The end parts of the two rotating shafts 8 close to each other are fixedly arranged with two transmission plates 7 in the radial direction, and the end parts of the two transmission plates 7 away from the rotating shafts 8 are connected through a connecting shaft parallel to the rotating shafts 8. The connecting shaft is fixedly connected with the two transmission plates 7, one end of the connecting rod 5 is rotatably connected with the connecting shaft, and the connecting shaft penetrates the end part of the connecting rod 5. The other end of the connecting rod 5 is hingedly connected with the movable plate 10.

[0032] A shovel plate 11 is arranged on the end part of the movable plate 10 away from the box opening, and the shovel plate 11 is arranged in the inclined direction of the movable plate 10. A sliding groove 9 is arranged in the end part of the shovel plate 11 close to the box opening in the inclined direction of the movable plate 10, and the end part of the movable plate 10 away from the box opening is inserted into the sliding groove 9 and is limitingly and slidingly connected with the movable plate 10.

[0033] In this embodiment, the cross section of the end part of the movable plate 10 away from the box opening is T-shaped, and the sliding groove 9 is matched with the end part of the movable plate 10 away from the box opening, so as to prevent the shovel plate 11 from being separated from the movable plate 10.

[0034] The shovel plate 11 and the movable plate 10 are drivingly connected through an elastic connecting member.

[0035] Specifically, the elastic connecting member includes a spring 12. The sliding groove 9 is arranged in the shovel plate 11, and the end part of the movable plate 10 away from the box opening is inserted into the sliding groove 9 and is limitingly and slidingly connected with the shovel plate 11. The spring 12 is arranged in the sliding groove 9 in the sliding direction of the shovel plate 11. One end of the spring 12 is fixedly connected with the shovel plate 11, and the other end is fixedly connected with the movable plate 10.

[0036] A guide rod 13 is arranged in the sliding groove 9 in the sliding direction of the shovel plate 11, the guide rod 13 is fixedly connected with the shovel plate 11, the guide rod 13 is inserted into the movable plate 10 and is slidingly connected with the movable plate 10.

[0037] In the embodiment, the camera for detecting foreign matters is located in front of the two cleaning rollers 4, and the two cleaning rollers 4 are located in front of the collecting box 6.

[0038] Working principle: when the detection mechanism is used to detect foreign matters on the runway, the controller controls the wheels to move along the runway. At the same time, the controller controls the camera to detect the runway below the vehicle body 1. If foreign matters are detected, the controller starts the two motors 2. The above technologies are prior art, and will not be described in detail here.

[0039] The output shafts of the two motors 2 drive the corresponding rotating shafts 8 to rotate, and the rotating shafts 8 drive the corresponding cleaning rollers 4 to clean the runway. When cleaning, the cleaning rollers 4 push the foreign matters onto the shovel plate 11 and then slide to the collecting box 6 through the shovel plate 11 and the movable plate 10 under the action of inertia.

[0040] When the two rotating shafts 8 rotate, the corresponding transmission plates 7 are driven to rotate, and the two transmission plates 7 drive the connecting shaft to revolve around the central axis of the two rotating shafts 8. The connecting shaft drives the connecting rod 5 to move reciprocally.

[0041] During the reciprocating movement of the connecting rod 5, the movable plate 10 is driven to slide reciprocally. At this time, the movable plate 10 slides reciprocally along the inclined direction to approach and move away from the runway. At the same time, the movable plate 10 drives the shovel plate 11 to reciprocally contact and move away from the runway through the spring 12. In the embodiment, the gap formed between the shovel plate 11 and the runway when the shovel plate 11 moves away from the runway is much smaller than the size of the foreign matters, and at the same time, the frequency of the reciprocating movement of the shovel plate 11 is much greater than the speed of the foreign matters moving from the cleaning roller 4 to the shovel plate 11, so as to ensure that the foreign matters will not slip away from the gap between the shovel plate 11 and the runway.

[0042] When the tire material adhering to the runway is cleaned, the shovel plate 11 cooperates with the movement of the vehicle body 1 to shovel the tire material at a high frequency, so as to ensure that the tire material is cleaned completely.

[0043] Finally, it should be pointed out that the above description is only the preferred embodiment of the present application and is not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
