[0017] The present invention provides a sweeper with an adjustable sweeping disc, which has the following beneficial effects:

[0018] 1. The present invention is provided with an adjustment mechanism. When performing cleaning work, if the road surface is damaged and potholes appear, the connecting ball at the bottom will contact and resist the obstacle protruding in front, and transmit it upward to the turntable A and the fixed plate A through the vertical bars and the block. The fixed plate A then pushes the turning ball B to the telescopic rod A for extension and retraction. Through the extension and retraction of the three telescopic rods A between the fixed plate A and the connecting plate and the tilting of the angle, the adaptive angle adjustment of the turntable A and the fixed plate A is realized. When encountering potholes, the lifting and pressing angles of the front of the turntable A are changed. After the angle is changed, the cleaning strip at the bottom of the turntable A will adapt to the pothole surface, so that it can rotate and sweep the pothole for cleaning, thereby realizing the cleaning work that adapts to various potholes and uneven road conditions, and also reducing the problem of bumps.

[0019] 2. The present invention is provided with an adjustment mechanism, and the surface of the connecting ball below is spherical, so that it can easily slide over various potholes on the road without affecting its driving. When the cleaning bar rotates, it will contact and move with the shifting bar, so that the cleaning bar can self-clean with elastic rebound, thereby completing the self-cleaning of the cleaning bar.

[0020] 3. The present invention sets an adjustment mechanism, and the connecting ball slides in the inner walls of the turntable A and the fixed disk A through the vertical bars and the card blocks, and the turntable A and the fixed disk A are connected by the circular plates extending from the upper and lower ends of the card blocks. At the same time, the card blocks can slide freely on the turntable A and the fixed disk A, so that when the connecting ball collides with an obstacle, the three cleaning bars will adaptively adjust the corresponding positions according to the resistance, so as to slide back and forth on the fixed disk A, and the three card blocks are interconnected through the annular bars, so that the three card blocks are evenly divided in the gap between the fixed disk A and the fixed disk B, thereby making the connection ball smoother when colliding with the obstacle and reducing obstruction.

[0021] 4. The present invention is provided with a pothole cleaning mechanism. During the working process in which the telescopic rod A is continuously stretched and shortened, the air inside the telescopic rod A is continuously replenished through the one-way air hole B, and then pushed into the telescopic rod B through the one-way air hole A, so that the telescopic rod B is continuously expanded, stretched and lengthened. After the telescopic rod B is elongated, the spring B is deformed, and the lowered lifting plate synchronously pushes the bristles to descend, and the rotating turntable B drives the telescopic rod B to rotate synchronously. The rotation of the telescopic rod B controls the rotation of the bristles through the lifting plate, so that when there are continuous potholes on the road section, the rotating lifting plate and the bristles are automatically pushed down to contact the potholes inside the pothole road surface, so that a large amount of stone particle residues originally mixed in the pothole road surface are completely cleaned out, and the dust and stains that are difficult to clean in the pothole road surface are correspondingly strengthened and cleaned. When it is not necessary, there is no need to lower the bristles, thereby reducing friction and loss. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a sweeper with an adjustable sweeping disc, comprising a sweeper 1, a connecting block 5 is provided on the outer wall of the sweeper 1, one end of the connecting block 5 is fixedly connected to a connecting disc 2, and an adjustment mechanism 3 is provided at the bottom of the connecting disc 2;

[0039] The adjustment mechanism 3 comprises:

[0040] The rotating ball A301 is a spherical structure. The outer wall of the rotating ball A301 is rotatably connected to the bottom of the connecting plate 2. A telescopic rod A302 is fixedly connected to the lower end of the rotating ball A301. A rotating ball B303 is fixedly connected to the lower end of the telescopic rod A302. The outer wall of the rotating ball B303 is rotatably connected to a fixed plate A304. The fixed plate A304 is an annular plate structure. The rotating ball A301 is used to control the opening, closing, rotation and lifting of the telescopic rod A302.

[0041] The turntable B308 is a circular plate-shaped structure. The top of the turntable B308 is fixedly connected to the motor 6. The outer wall of the motor 6 is fixedly connected to the connecting rod 313. One end of the connecting rod 313 is fixedly connected to the fixed disk B312. The top of the fixed disk A304 is fixedly connected to the spring A305. One end of the spring A305 is fixedly connected to the bottom of the connecting disk 2. The turntable B308 is used to be driven to rotate by the motor 6;

[0042] When in use, when the sweeper 1 is driving, the connecting block 5 pushes the connecting plate 2 to move the adjusting mechanism 3 at the bottom, and at the same time starts the motor 6 to drive the turntable B308 at the bottom to rotate. The turntable B308 controls the turntable A306 to rotate synchronously through the magnetic attraction between the magnetic slots A309 and the magnetic slots B310. When the turntable A306 rotates, it drives the cleaning strip 307 at the bottom to rotate, thereby cleaning the dust at the bottom.

[0043] Example 2: Please refer to Figure 1-11On the basis of the first embodiment, the present invention provides a technical solution: a magnetic groove A309 is provided on the outer wall of the turntable B308, a turntable A306 is rotatably connected to the bottom of the fixed disk A304, and a magnetic groove B310 is provided on the inner wall of the turntable A306.

[0044] The magnetic slot A309 and the magnetic slot B310 are magnetic, and the magnetism of the magnetic slot A309 and the magnetic slot B310 on the opposite side is that opposite poles attract each other. A cleaning bar 307 is fixedly connected to the bottom of the turntable A306.

[0045] A block 315 is slidably connected between the top of the fixed disk B312 and the bottom of the rotating disk B308. The outer wall of the block 315 is fixedly connected to a ring bar 314. The bottom of the block 315 is fixedly connected to a vertical bar 316. The bottom of the vertical bar 316 is fixedly connected to a connecting ball 317.

[0046] The bottom of the connecting ball 317 is fixedly connected with a pull bar 318, the outer wall of the pull bar 318 contacts the outer wall of the cleaning bar 307, and the outer wall of the telescopic rod A302 is provided with a pothole cleaning mechanism 4;

[0047] Since the fixed disk A304 is restricted by the rotating ball A301, the telescopic rod A302 and the rotating ball B303, the telescopic length of the telescopic rod A302 is limited, and the fixed disk A304 cannot rotate. The fixed disk A304 is connected to the fixed disk B312 through the connecting bent bar 311, and the fixed disk B312 is connected to the motor 6 through the connecting rod 313, so that the motor 6 is limited at this time, so that the motor 6 remains in a stationary state, thereby controlling the rotating disk B308 and the rotating disk A306 and the cleaning strip 307 at the bottom to perform rotating cleaning work;

[0048] When cleaning, if the road surface is damaged and there are potholes, the connecting ball 317 at the bottom will contact and resist the raised obstacle in front, and transmit it upward to the turntable A306 and the fixed plate A304 through the vertical bar 316 and the block 315. The fixed plate A304 then pushes the turning ball B303 to the telescopic rod A302 for extension and retraction. Through the extension and tilt of the three telescopic rods A302 between the fixed plate A304 and the connecting plate 2, the adaptive angle adjustment of the turntable A306 and the fixed plate A304 is achieved. When encountering potholes, the lifting and pressing angles of the front of the turntable A306 are changed. After the angle is changed, the cleaning strip 307 at the bottom of the turntable A306 will adapt to the pothole surface, so that it can rotate and sweep the potholes to clean, thereby achieving the cleaning work that adapts to various potholes and uneven road conditions, and also reduces the problem of bumps.

[0049] The surface of the lower connecting ball 317 is spherical, so it can easily slide over various potholes on the road without affecting its driving. When the cleaning strip 307 rotates, it will contact and move with the dial bar 318, so that the cleaning strip 307 can self-clean with elastic rebound, thus completing the self-cleaning of the cleaning strip 307.

[0050] At the same time, the connecting ball 317 slides in the inner wall of the rotating disk A306 and the fixed disk A304 through the vertical bar 316 and the block 315, and the rotating disk A306 and the fixed disk A304 are connected by the circular plates extending from the upper and lower ends of the block 315. At the same time, the block 315 can slide freely on the rotating disk A306 and the fixed disk A304, so that when the connecting ball 317 collides with an obstacle, the three cleaning bars 307 can adaptively adjust the corresponding positions according to the resistance, so as to slide back and forth on the fixed disk A304, and the three blocks 315 are connected to each other through the annular bar 314, so that the three blocks 315 are evenly divided in the gap between the fixed disk A304 and the fixed disk B312, thereby more effectively making the collision of the connecting ball 317 with the obstacle smoother and reducing obstacles;

[0051] Example 3: Please refer to Figure 1-15 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the pothole cleaning mechanism 4 includes an air pipe 401, one end of the air pipe 401 is fixedly connected to the outer wall of the telescopic rod A302, and the other end of the air pipe 401 is fixedly connected to the top of the fixed plate B312.

[0052] An annular air groove 402 is provided at the top of the turntable B308, the top of the annular air groove 402 is connected to the interior of the fixed disk B312, the interior of the fixed disk B312 is connected to the interior of the air pipe 401, the interior of the annular air groove 402 is connected to the interior of the one-way air hole A403, and a telescopic rod B404 is fixedly connected to the bottom of the turntable B308.

[0053] One end of the telescopic rod B404 is fixedly connected to a lifting plate 405, the bottom of the lifting plate 405 is fixedly connected to bristles 407, the top of the lifting plate 405 is fixedly connected to a spring B406, one end of the spring B406 is fixedly connected to the bottom of the turntable B308, an air vent 408 is provided on the outer wall of the telescopic rod B404, the inner wall of the air vent 408 is connected to the inside of the telescopic rod B404, and the inside of the telescopic rod B404 is connected to the inside of the one-way air hole A403;

[0054] When encountering a bumpy and continuous pothole section, the telescopic rod A302 will frequently stretch and retract back and forth. Because when the telescopic rod A302 is squeezed and shortened, the air on the inner wall of the telescopic rod A302 will be squeezed into the air pipe 401, enter the fixed plate B312 through the air pipe 401, enter the annular air groove 402 through the bottom of the fixed plate B312, enter the one-way air hole A403 through the annular air groove 402, and then directly enter the telescopic rod B404 at the bottom. , air enters the telescopic rod B404 to expand and retract, pushing the lifting plate 405 down, and when the telescopic rod A302 is stretched, air will not be replenished through the telescopic rod B404, because the one-way air hole A403 has one-way air intake, so air can only be replenished through the one-way air hole B409, and the one-way air hole B409 also has one-way air intake, so when the telescopic rods A302 are squeezed against each other, air will not escape through the one-way air hole B409, so when the telescopic rods A302 are not During the continuous stretching and shortening working process, the air inside the telescopic rod A302 is continuously replenished through the one-way air hole B409, and then pushed into the telescopic rod B404 through the one-way air hole A403, so that the telescopic rod B404 is continuously expanded and stretched to become longer. After the telescopic rod B404 is stretched, the spring B406 is deformed, and the lowered lifting plate 405 synchronously pushes the bristles 407 to descend, and the rotating turntable B308 drives the telescopic rod B404 to rotate synchronously. The rotation of the telescopic rod B404 controls the rotation of the bristles 407 through the lifting plate 405, so that when there are continuous potholes on the road section, the rotating lifting plate 405 and the bristles 407 will be automatically pushed down to contact the potholes inside the pothole road surface, and a large amount of stone particles and residues originally mixed in the pothole road surface will be completely cleaned out, and the dust and stains that are difficult to clean in the pothole road surface will be correspondingly strengthened. When it is not necessary, there is no need to lower the bristles 407, thereby reducing friction and loss.

[0055] In the case of fewer potholes on the road, the air squeezed into the telescopic rod B404 will pull the lifting plate 405 with the elastic force of the spring B406, and the air in the telescopic rod B404 will be squeezed out through the vent 408 on the outer wall. Only when the air added to the telescopic rod B404 is greater than the air discharged from the vent 408, the telescopic rod B404 will continue to extend. Therefore, only on the road with continuous potholes and bumps can the bristles 407 be pushed down for cleaning. On the road with few bumps and no continuous potholes, there is no need to lower the bristles 407 for detailed cleaning. Otherwise, the friction force will be greatly increased, the sweeper 1 will encounter resistance when traveling, and a large number of bristles 407 will cause unnecessary excessive wear.

[0056] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
