Two threaded holes are provided on the movable plate 7, and two screw rods 6 pass through adjacent threaded holes. A lower scraper plate 8 is fixedly connected to the right side of the lower movable plate 7, and the right side of the lower scraper plate 8 fits with the outer surface of the rolling wheel 4. An upper scraper plate 9 is fixedly connected to the right side of the upper movable plate 7, and the right side of the upper scraper plate 9 and the right side of the lower scraper plate 8 are located on the same vertical line. A motor 10 is arranged on the top surface of the inner wall of the connecting frame 3 near the left side, and the upper end surface of the front screw rod 6 is fixedly connected to the shaft of the motor 10, and a cleaning mechanism is arranged in the inner cavity of the connecting frame 3.

[0019] In order to facilitate the cleaning of dirt adhered to the bottom surfaces of the upper scraper 9 and the lower scraper 8, the cleaning mechanism includes a first fixed plate 11, the top surface and the bottom surface of the first fixed plate 11 are respectively fixedly connected to the facing surfaces of the two movable plates 7, the bottom surface of the lower movable plate 7 is fixedly connected to the second fixed plate 12, the right side of the first fixed plate 11 near the top and the right side of the second fixed plate 12 near the bottom are fixedly connected to a cylinder 13, the right sides of the two cylinders 13 are commonly fixedly connected to a connecting plate 14, the right side of the connecting plate 14 is fixedly connected to a cleaning plate 15 near the top and the bottom, and the top surfaces of the two cleaning plates 15 are respectively slidably connected to the bottom surfaces of the lower scraper 8 and the upper scraper 9.

[0020] In order to enable the two screw rods 6 to rotate simultaneously, pulleys 16 are fixedly sleeved on the upper ends of the surfaces of the two screw rods 6 , and a transmission belt 17 is sleeved on the two pulleys 16 . The two pulleys 16 are connected through the transmission belt 17 .

[0021] In order to limit the movable plate 7 and prevent the movable plate 7 from moving up and down more stably, a slide groove 18 is opened on the left side of the inner wall of the connecting frame 3, and a slider 19 is fixedly connected to the left side of the two movable plates 7, and the left side of the slider 19 is slidably connected in the slide groove 18.

[0022] In order to allow the connecting plate 14 to pass through the lower scraper 8 and prevent the lower scraper 8 from affecting the left and right movement of the connecting plate 14 , a movable opening 20 is opened on the connecting plate 14 , and the movable opening 20 is adapted to the lower scraper 8 .

[0023] In order to facilitate the insertion of the cleaning tool into the inner side of the connecting frame 3 to clean the cleaning plate 15, a cleaning opening 21 is opened on the front and rear sides of the connecting frame 3, and a baffle 22 is inserted into the cleaning opening 21. The two baffles 22 are bolted to the front and rear sides of the connecting frame 3.

[0024] Working principle: When the utility model is used, the device moves on the ground, and the rolling wheel 4 can be rotated inside the connecting frame 3, and the rolling wheel 4 rolls the ground. Dirt will adhere to the outer surface of the rolling wheel 4 when rolling the ground. Since the right side of the lower scraper 8 is in contact with the outer surface of the rolling wheel 4, the lower scraper 8 will scrape off the dirt adhered to the outer surface of the rolling wheel 4 when the rolling wheel 4 rotates, thereby cleaning the rolling wheel 4. When the lower scraper 8 scrapes off the dirt, some of the dirt will adhere to the lower scraper 8 and accumulate more and more, affecting the cleaning effect of the rolling wheel 4. At this time, the motor 10 is started, and the motor 10 drives the front screw rod 6 to rotate. The front screw rod 6 drives the rear screw rod 6 to rotate synchronously through the cooperation of the pulley 16 and the transmission belt 17. The rotation of the screw rod 6 will cause the two movable plates 7 to descend, and the lower movable plate 7 drives the lower scraper 8 to descend. , so that the right side of the lower scraper 8 no longer fits the outer surface of the rolling wheel 4, and at the same time, the movable plate 7 on the upper side drives the upper scraper 9 to descend, so that the right side of the upper scraper 9 fits the outer surface of the rolling wheel 4. When the right sides of the lower scraper 8 and the upper scraper 9 are not in contact with the rolling wheel 4, the cylinder 13 is started, and the cylinder 13 pushes the connecting plate 14 to move right, and the connecting plate 14 drives the cleaning plate 15 to move right. The two cleaning plates 15 move right to scrape the bottom surfaces of the lower scraper 8 and the upper scraper 9 respectively, and scrape off the dirt adhered to the bottom surfaces of the lower scraper 8 and the upper scraper 9, so that the lower scraper 8 and the upper scraper 9 can be repeatedly switched to clean the rolling wheel 4, ensuring the cleaning effect of the rolling wheel 4, twisting the bolt to remove the baffle 22 from the connecting frame 3, and then the cleaning tool can be extended into the interior of the connecting frame 3 through the two cleaning openings 21 on the front and rear sides, so as to facilitate the cleaning of the cleaning plate 15.

[0025] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
