[0008] By adopting the above technical solution, the motor seat drives the collection box and the grinding wheel to approach the ground. When the grinding wheel grinds the raised part, the length direction of the scraper is parallel to the plane where the opening of the collection box is located. The scraper is driven to slide in the direction away from the collection box through the sliding mechanism, so that the scraper extends out of the collection box and disengages from the opening of the collection box until the scraper is close to the side wall of the collection box and abuts against the corresponding rotating rod. Then the rotating rod is driven by the rotating member to drive the scraper to rotate in the direction close to the opening of the collection box. As the machine body moves forward, the scraper scrapes the ground debris into the collection box, thereby realizing synchronous cleaning of the debris without the need for subsequent manual operation, which helps to reduce labor intensity.

[0012] By adopting the above technical solution, when the scraper rotates to abut against the opening of the collection box, the second gear is adjusted by the adjusting component to move toward the rack on the corresponding scraper, so that the second gear is meshed with the rack close to one side, and then the second motor is used to drive the second gear to rotate, and the second gear drives the rack and the scraper to slide in the direction away from the collection box. When the scraper is close to the collection box and is moved to the rotating rod, the gear seat is adjusted by the adjusting component to drive the second gear away from the rack, so that the second gear is disengaged from the rack. At this time, under the action of the corresponding magnet and iron sheet, the scraper continues to move toward the side away from the collection box, so that the scraper is close to the collection box. The side of the collection box is abutted against the rotating rod, and then the fan gear continues to drive the rotating rod and the scraper to rotate in the direction close to the opening of the collection box, which helps to continuously clean up the debris on the ground. It is simple and convenient, and saves manpower to a certain extent.

At this time, the first pushing member pushes the abutment rod to slide out of the collection box in the direction close to the scraper, so that the connecting rope pulls the gear seat to drive the second gear to slide in the direction away from the scraper, and the second gear is disengaged from the rack, which facilitates the adsorption between the magnet and the iron sheet, and helps the rotating rod to continue to drive the scraper to rotate, providing convenience for cleaning debris on the ground, and helping to reduce the labor intensity of workers.

[0019] Preferably, the length of the scraper is greater than half the length of the collection box, and when the scraper on one side abuts against the opening of the collection box, the scraper on the other side is separated from the collection box.

[0020] By adopting the above technical solution, the length of the scraper is greater than half the length of the collection box, and the scraper rotates crosswise, which helps to expand the cleaning range.

[0028] Step 4: Then the rotating member drives the rotating rod and the scraper to rotate intermittently in the direction close to the collection box. When the machine body moves forward, the scraper scrapes the debris on the ground into the collection box until the scraper abuts against the collection box and is parallel to the plane where the opening of the collection box is located. The rotating rod stops rotating and drives the scraper to slide in the direction away from the collection box through the sliding mechanism, so that the scraper is separated from the collection box.

[0029] Step 5: The rotating member then continues to drive the rotating rod to drive the scraper to rotate toward the direction close to the collection box, and the debris on the ground is continuously cleaned in this reciprocating manner.

[0030] In summary, this application includes the following beneficial technical effects:

[0031] The motor seat drives the collection box and the grinding wheel towards the ground. When the grinding wheel grinds the raised part, the length direction of the scraper is parallel to the plane where the opening of the collection box is located. The scraper is driven to slide in the direction away from the collection box through the sliding mechanism, so that the scraper extends out of the collection box and disengages from the opening of the collection box until the scraper is close to the side wall of the collection box and abuts against the corresponding rotating rod.

The fixing rods 19 are located in the middle of the collection box 3. The collection box 3 is located on the side away from the advancing direction of the grinding wheel. The opening of the collection box 3 is arranged toward the grinding wheel. The lower surface of the collection box 3 is flush with the lower surface of the grinding wheel. A first support plate 11 is relatively fixed on the side wall of the collection box 3 close to the grinding wheel. The first support plate 11 extends in the direction close to the grinding wheel. A rotating rod 4 is rotatably penetrated on the first support plate 11. The rotation axis of the rotating rod 4 is perpendicular to the plane where the grinding wheel is located. A scraper 5 is slidably sleeved on the rotating rod 4. The length of the scraper 5 is greater than half the length of the collection box 3. The height of the scraper 5 is greater than the thickness of the collection box 3. The scraper 5 is used to scrape the debris on the ground into the collection box 3. The sliding direction of the scraper 5 is perpendicular to the rotation axis of the rotating rod 4. A rotating member 6 for driving the rotating rod 4 to rotate intermittently is arranged on the collection box 3. In other embodiments, bristles are arranged on the bottom wall of the scraper 5 as needed.

[0042] Reference Figure 2 and Figure 3In order to facilitate the intermittent rotation of the rotating rod 4, the rotating rod 4 extends above the scraper 5, and the top wall of the collecting box 3 is relatively fixed with a second support plate 12. The rotating member 6 includes a first gear 61 fixedly mounted on the rotating rod 4, a fan-shaped gear 62 rotatably arranged on the second support plate 12, and a first motor 63 fixedly mounted on the top wall of the collecting box 3.

The second motor 76 drives the second gear 73 to rotate, and the second gear 73 drives the rack 71 and the scraper 5 to slide in the direction away from the collecting box 3, and then the scraper 5 gradually disengages from the corresponding abutment rod 771, and the first spring 7731 pushes the abutment rod 771 to extend in the direction away from the collecting box 3, and the gear seat 72 is pulled by the connecting rope 772 to disengage the second gear 73 from the rack 71, and the infrared The external receiver 21 is misaligned with the infrared transmitter 20, and the corresponding second motor 76 stops working. At this time, the scraper 5 continues to slide in the direction away from the collection box 3 through the adsorption between the magnet 74 and the iron sheet 75, until the side of the scraper 5 close to the collection box 3 abuts against the side of the rotating rod 4 close to the collection box 3. At this time, the sector gear 62 rotates to the position of the first gear 61 and gradually meshes with the first gear 61, so that the rotating rod 4 continues to drive the scraper 5 to rotate and reset, and in this way, the continuous cleaning of the ground on the other side is achieved during the continuous advancement of the machine body 1, without the need for subsequent manual operation, which helps to save manpower.

The fan gear 62 on the side where the scraper 5 is separated from the collecting box 3 drives the first gear 61, the rotating rod 4 and the scraper 5 to rotate 180° in the direction close to the collecting box 3. Then the scraper 5 gradually abuts against the abutment rod 771 on the corresponding side, pushing the corresponding abutment rod 771 to slide in the direction close to the collecting box 3. The tension of the connecting rope 772 on the gear seat 72 is reduced, and the second spring 7741 pushes the gear seat 72 to drive the second gear 73 close to the scraper 5 until the scraper 5 rotates to abut against the opening of the collecting box 3, and the rack 7 1 meshes with the second gear 73, and the debris is pushed into the collection box 3; (2) the initial state is that the fan-shaped gear 62 on the side where the scraper 5 abuts against the collection box 3 continues to disengage from the first gear 61 during rotation, the infrared receiver 21 is aligned with the infrared transmitter 20, and the control system drives the second motor 76 to drive the second gear 73 to rotate, and the second gear 73 drives the rack 71 and the scraper 5 away from the collection box 3 until the scraper 5 is disengaged from the abutment rod 771, and the connecting rope 772 pulls the gear seat 72 to disengage the second gear 73 and the rack 71, and under the adsorption of the magnet 74 and the corresponding side iron sheet 75, the scraper 5 close to the collection box 3 abuts against the side of the rotating rod 4 close to the collection box 3, and the scraper 5 is disengaged from the collection box 3;

[0062] Step 5: Then the sector gear 62 continues to drive the rotating rod 4 to drive the scraper 5 to rotate towards the direction close to the collection box 3, and the debris on the ground is continuously cleaned in this reciprocating manner.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
