[0041] Further, cleaning device 2 includes bottom plate 201, first mounting shell 202 is arranged on bottom plate 201, adjusting part is fixedly connected in first mounting shell 202, and the end of adjusting part is rotatably connected with cleaning rod 205;Protection device 3 includes second mounting shell 301, pusher and protection part are fixedly connected in second mounting shell 301;When metal object on the surface of tire 5 is removed by cleaning rod 205, pusher pushes protection part out from second mounting shell 301, so that protection part is hooked on the surface of tire 5 and protects tire 5. Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 And Figure 6The adjusting member is a motor or a first motor 203, and in this embodiment, the first motor 203 is preferably used. The first motor 203 is fixedly connected with the cleaning rod 205 and used to adjust the working angle of the cleaning rod 205. When the metal detector detects that there is metal attachment on the surface of the tire 5, the cleaning rod 205 is driven to rotate, so that the end of the cleaning rod 205 faces the surface of the tire 5. (It is worth noting that the angle at which the first motor 203 drives the cleaning rod 205 to rotate can be obtained through limited tests and preset in the controller in advance, which is a prior art and will not be described in detail in this embodiment.) In order to avoid damage to the first motor 203 during the cleaning of the metal object, a connecting rod 204 is fixedly connected to the end of the first motor 203. The connecting rod 204 is rotatably connected with the first through hole 2051 of the cleaning rod 205. During the operation of the cleaning rod 205, the rotatable connection between the connecting rod 204 and the cleaning rod 205 does not affect the normal operation. The end of the cleaning rod 205 is fixedly connected with a protective plate 2053, and the cross section of the protective plate 2053 is arc-shaped. The protective plate 2053 is used to block the cleaned metal object. The end of the protective plate 2053 is welded with a cleaning plate 2054.

Under the action of the rotating force of the tire 5, the cleaning plate 2054 removes the metal object from the surface of the tire 5. After the cleaning is completed, the protective member is ready to be put into place. Since the protective member is made of metal and has a certain deformation ability, the protective member is wound and placed in the second installation shell 301. Under the action of the top of the second installation shell 301, the protective member is tightly pressed in the second installation shell 301. However, since there are speed reduction belts arranged at intervals on the road, in order to avoid the protective member from being shaken off when the car passes through the speed reduction belt, a third motor 306 is fixedly connected to the bottom of the second installation shell 301. The driving end of the third motor 306 is fixedly connected with a blocking plate. The blocking plate is used to intercept the protective member. After the metal object on the surface of the tire 5 is removed, the second motor 304 drives the blocking plate to rotate to a parallel angle with the second installation shell 301, and the pushing member slowly pushes the protective member outward.

[0042] The bottom of the second installation shell 301 is fixedly connected with a second motor 304. The driving end of the second motor 304 is fixedly connected with an intercepting plate. The intercepting plate is used to intercept the protective member. After the metal object on the surface of the tire 5 is removed, the second motor 304 drives the intercepting plate to rotate to a parallel angle with the second installation shell 301, and the pushing member slowly pushes the protective member outward. In order to avoid the protective member from falling off the surface of the tire 5, a third motor 306 is fixedly connected to the bottom of the second installation shell 301. The driving end of the third motor 306 is fixedly connected with a blocking plate. The blocking plate is used to intercept the protective member. After the metal object on the surface of the tire 5 is removed, the second motor 304 drives the blocking plate to rotate to a parallel angle with the second installation shell 301, and the pushing member slowly pushes the protective member outward. Figure 7 and Figure 8As shown, the guard is a guard net 303, the guard net 303 comprises a net body 3031, both ends of the net body 3031 are provided with hooks 3032, and the guard device 3 further comprises a short rod, the short rod is welded on opposite sides of the tire 5 before driving the automobile, after the pushing member pushes the guard net 303 by a certain distance, the hook 3032 at one end of the net body 3031 is hooked and connected with the short rod along with the rotation of the tire 5, and the other end of the net body 3031 is also hooked and connected with the short rod due to the influence of the rotation of the tire 5, so that the guard net 303 protects the surface of the tire 5, and the end of the short rod is fixedly connected with a baffle, the baffle can prevent the hooks 3032 on the guard net 303 from falling off.

[0043] Further, the pushing member is a micro air cylinder 302, the micro air cylinder 302 makes the hooks 3032 on the guard net 303 coincide with the rotation track of the short rod along with the rotation of the tire 5 in the process of pushing the guard net 303, as shown in the figure, Figure 1 The pushing distance of the pushing member can also be obtained through a limited number of tests, and the embodiment will not be described in detail.

[0044] When the driver drives the automobile to the safe area (service area), the driver gets off the automobile immediately, rotates and folds the removing rod 205, and fixes and connects the connecting rod through hole 2041 and the second through hole 2052 by a screw, as shown in the figure, Figure 5 When the driver drives the automobile to the safe area (service area), the driver gets off the automobile immediately, rotates and folds the removing rod 205, and fixes and connects the connecting rod through hole 2041 and the second through hole 2052 by a screw, as shown in the figure,

[0045] The above is only the preferred embodiment of the present application and is not used to limit the present application, for those skilled in the art, the present application can have various changes and variations.
