When the main body walks on the inclined ground, the water in the two first through holes moves the sealing plates and makes the two sealing plates on the same horizontal plane. Then, through the support of the moving rod, the rotating plate rotates and becomes horizontal. At this time, the supporting column is vertical, and the fixed body is also vertical, so that the rotating plates on the two rotating bodies keep the wall vertical through the transmission mechanism during the rotating and smoothing process;

[0014] 2. By setting the first motor and the rigid wire, the first motor causes the pulley to drive the rigid wire to contract, pulls the second connecting rod, causes the second connecting rod to rotate, and the second connecting rod drives the fixed body to approach the support column. At this time, the height of the fixed body increases, and the high wall can be smoothed by the rotating plate. When the first motor stops, the fixed body automatically drops due to gravity, and the second connecting rod drives the fixed body away from the support column until the rotating plate touches the wall. At this time, the low wall can be smoothed by the rotating plate;

[0015] 3. By setting a fixed shaft, a protrusion and a V-shaped rotating plate, when the second motor drives the rotating plate to rotate counterclockwise, the smooth side of the rotating plate contacts the wall, and the wall can be finely ground. By rotating the fixed shaft connected to the rotating body, the rotating plate can be rotated so that the side of the rotating plate with the protrusion contacts the wall, and the second motor is rotated clockwise, so that the wall can be coarsely ground.

[0016] 4. By setting up an infrared rangefinder, a single-chip microcomputer and a steering mechanism, the infrared rangefinder can determine the distance between the main body and the wall. When the distance between the main body and the wall changes, the single-chip microcomputer receives a signal and makes the steering mechanism turn, so that the distance between the main body and the wall is always fixed, ensuring the stability of the rotating plate when working;

[0017] 5. By setting up a second motor, a pulley, a belt and a protective net, the second motor can drive the rotating shaft to rotate. The rotating shaft can drive the two second pulleys to rotate through the first pulley and the two belts. The two second pulleys drive the rotating shaft to rotate. The rotating shaft drives the rotating body to rotate, so that the rotating plate rotates to smooth the wall. The protective net can protect the second motor and facilitate the heat dissipation of the second motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

There is a rotating shaft 19, one end of which is welded with a rotating body 14, the outer wall of the rotating body 14 is rotatably connected with a fixed shaft 22, and one end of the fixed shaft 22 is provided with a rotating plate 13. The main body 1 can walk on the ground through rollers. Through the connection of the first connecting rod 7 and the second connecting rod 8, the support column 6 is parallel to the fixed body 11, and the water inside the water storage tank 2 enters the two first through holes. The water surfaces in the first through holes are in the same horizontal plane. When the main body 1 walks on the inclined ground, the water in the two first through holes moves the sealing plate 17 and makes the two sealing plates on the same horizontal plane. Then, through the support of the moving rod 16, the rotating plate 3 is rotated and becomes horizontal. At this time, the support column 6 is vertical, and the fixed body 11 is also vertical, so that the rotating plates 13 on the two rotating bodies 14 keep the wall vertical through the transmission mechanism during the rotating and smoothing process.

[0029] In the present invention, a rubber sealing pad is bonded to the bottom end of the sealing plate 17 to prevent the water in the water storage tank 2 from flowing out.

[0030] Among them, a fixing seat is welded on one side of the support column 6, and the top of the fixing seat is fixedly connected to the first motor 5 by bolts. A pulley is connected to the output shaft of the first motor 5 by a key, and a rigid wire 4 is bonded to the outside of the pulley. The other end of the rigid wire 4 is bonded to the second connecting rod 8. The first motor 5 can be started to make the pulley drive the rigid wire 4 to contract, and the second connecting rod 8 is pulled to rotate the second connecting rod 8. The second connecting rod 8 drives the fixed body 11 to approach the support column 6. At this time, the height of the fixed body 11 increases, and the high wall can be smoothed by the rotating plate 13. When the first motor 5 is turned, the fixed body 11 automatically drops due to gravity, and the second connecting rod 8 drives the fixed body 11 away from the support column 6 until the rotating plate 13 contacts the wall. At this time, the low wall can be smoothed by the rotating plate 13.

[0031] Wherein, the transmission mechanism includes a second motor 10, a first pulley 15, a second pulley 18, two belts 20 and a rotating shaft 21. A square through hole is opened in the middle of the fixed body 11. The second motor 10 is located inside the square through hole and is fixedly connected to the fixed body 11 by bolts.

The outside of the rotating shaft 21 and the rotating shaft 19 are respectively fixedly connected to the first pulley 15 and the second pulley 18 by keys. The two belts 20 are located outside the first pulley 15 and the second pulley 18. The rotation of the second motor 10 can drive the rotating shaft 21 to rotate. The rotating shaft 21 can drive the two second pulleys 18 to rotate through the first pulley 15 and the two belts 20. The two second pulleys 18 drive the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating body 14 to rotate, so that the rotating plate 13 rotates to smooth the wall.

[0032] Among them, a protective net 9 is fixedly connected to one side of the fixed body 11 by screws. The protective net 9 is located on one side of the second motor 10 . The protective net 9 can protect the second motor 10 and facilitate the heat dissipation of the second motor 10 .

[0033] Among them, the rotating plate 13 is V-shaped, a fixed plate 23 is welded to one end of the rotating plate 13, one side of the fixed plate 23 is welded to the fixed shaft 22, a plurality of protrusions 24 are provided on one side of the rotating plate 13, the protrusions 24 are hemispherical, and the other side of the rotating plate 13 is smooth. When the second motor 10 drives the rotating plate 13 to rotate counterclockwise, the smooth side of the rotating plate 13 contacts the wall, and the wall can be finely ground. Through the fixed shaft 22 rotatably connected to the rotating body 14, the rotating plate 13 can be rotated so that the side of the rotating plate 13 with the protrusion 24 contacts the wall, and the second motor 10 is rotated clockwise, so that the wall can be coarsely ground.

[0034] When in use, the main body 1 can walk on the ground through the rollers. Through the connection of the first connecting rod 7 and the second connecting rod 8, the support column 6 is parallel to the fixed body 11, and the water inside the water storage tank 2 enters the two first through holes. The water levels in the first through holes are at the same horizontal plane. When the main body 1 walks on the inclined ground, the water in the two first through holes moves the sealing plate 17 and makes the two sealing plates on the same horizontal plane. Then, through the support of the moving rod 16, the rotating plate 3 is rotated and horizontal. At this time, the support column 6 is vertical, and the fixed body 11 is also vertical, so that the rotating plates 13 on the two rotating bodies 14 can keep the wall vertical during the rotating and trowelling process through the transmission mechanism;

[0035] The rotation of the second motor 10 can drive the rotating shaft 21 to rotate, and the rotating shaft 21 can drive the two second pulleys 18 to rotate through the first pulley 15 and the two belts 20, and the two second pulleys 18 drive the rotating shaft 19 to rotate, and the rotating shaft 19 drives the rotating body 14 to rotate, so that the rotating plate 13 rotates to perform a smoothing operation on the wall;

[0036] The first motor 5 can be started to cause the pulley to drive the rigid wire 4 to contract, and the second connecting rod 8 can be pulled to rotate the second connecting rod 8, and the second connecting rod 8 can drive the fixed body 11 to approach the support column 6. At this time, the height of the fixed body 11 increases, and the high wall can be smoothed by the rotating plate 13. When the first motor 5 is turned on, the fixed body 11 automatically drops due to gravity, and the second connecting rod 8 drives the fixed body 11 away from the support column 6 until the rotating plate 13 contacts the wall. At this time, the low wall can be smoothed by the rotating plate 13;

[0037] When the second motor 10 drives the rotating plate 13 to rotate counterclockwise, the smooth side of the rotating plate 13 contacts the wall, so the wall can be finely ground. Through the fixed shaft 22 rotatably connected to the rotating body 14, the rotating plate 13 can be rotated so that the side of the rotating plate 13 with the protrusion 24 contacts the wall, and the second motor 10 is rotated clockwise, so the wall can be coarsely ground.

The single-chip computer 26 is electrically connected to the infrared rangefinder 25 and the steering mechanism. The infrared rangefinder 25 can determine the distance between the main body 1 and the wall. When the distance between the main body 1 and the wall changes, the single-chip computer 26 receives a signal and makes the steering mechanism turn, so that the distance between the main body 1 and the wall is always fixed, thereby ensuring the stability of the rotating plate 13 when working.

[0040] When in use, the main body 1 can walk on the ground through the rollers. Through the connection of the first connecting rod 7 and the second connecting rod 8, the support column 6 is parallel to the fixed body 11, and the water inside the water storage tank 2 enters the two first through holes. The water levels in the first through holes are at the same horizontal plane. When the main body 1 walks on the inclined ground, the water in the two first through holes moves the sealing plate 17 and makes the two sealing plates on the same horizontal plane. Then, through the support of the moving rod 16, the rotating plate 3 is rotated and horizontal. At this time, the support column 6 is vertical, and the fixed body 11 is also vertical, so that the rotating plates 13 on the two rotating bodies 14 can keep the wall vertical during the rotating and trowelling process through the transmission mechanism;

[0041] The rotation of the second motor 10 can drive the rotating shaft 21 to rotate, and the rotating shaft 21 can drive the two second pulleys 18 to rotate through the first pulley 15 and the two belts 20, and the two second pulleys 18 drive the rotating shaft 19 to rotate, and the rotating shaft 19 drives the rotating body 14 to rotate, so that the rotating plate 13 rotates to perform a smoothing operation on the wall;

When the first motor 5 is turned on, the fixed body 11 automatically drops due to gravity, and the second connecting rod 8 drives the fixed body 11 away from the support column 6 until the rotating plate 13 contacts the wall. At this time, the low wall can be smoothed by the rotating plate 13;

[0043] When the second motor 10 drives the rotating plate 13 to rotate counterclockwise, the smooth side of the rotating plate 13 contacts the wall, and the wall can be finely ground. The rotating plate 13 can be rotated by the fixed shaft 22 rotatably connected to the rotating body 14, so that the side of the rotating plate 13 with the protrusion 24 contacts the wall, and the second motor 10 is rotated clockwise, so that the wall can be roughly ground.

[0044] The infrared rangefinder 25 can determine the distance between the main body 1 and the wall.
