At the same time, by arranging the rotating mechanism 22, the U-turn operation of the floor scrubber can be realized, which is convenient for repeated testing of the floor scrubber.

[0019] The reciprocating mechanism 6 includes a first gear 9 and a second gear 10, which are rotatably mounted in the middle of the central cavity 4, and the first gear 9 and the second gear 10 are meshed. When the first gear 9 rotates, the second gear 10 also rotates, and the first gear 9 and the second gear 10 rotate in opposite directions. A first sector rack 11 is fixedly arranged above the first gear 9, and a second sector rack 12 is fixedly arranged above the second gear 10. The first sector rack 11 and the second sector rack 12 are in opposite directions, and the interior of the central cavity 4 slides symmetrically. The movable table 13 is provided with two movable tables 13, and the movable table 13 includes a first movable table 33 and a second movable table 34. The first movable table 33 and the second movable table 34 are respectively arranged on both sides of the first gear 9 and the second gear 10. The first movable table 33 and the second movable table 34 are both arranged in a T shape, and the end surfaces of the tops of the first movable table 33 and the second movable table 34 are both provided with matching racks 14, and the matching racks 14 are meshed with the first sector rack 11 and the second sector rack 12.

When the first gear 9 and the second gear 10 rotate, the first sector rack 11 and the second sector rack 12 at the top thereof will also rotate, so that the first sector rack 11 and the second sector rack 12 can control the first platform 33 and the second platform 34 in turn. When the first gear 9 rotates clockwise and the second gear 10 rotates counterclockwise, the first sector rack 11 drives the first platform 33 to move forward, and the second sector rack 12 drives the first platform 33 to move forward. The second moving platform 34 is driven to move forward, and the first moving platform 33 and the second moving platform 34 can move toward the front of the central cavity 4 at the same time. After rotating a certain angle, the directions of the first sector rack 11 and the second sector rack 12 are swapped. At this time, the first sector rack 11 drives the second moving platform 34 to move backward, and the second sector rack 12 drives the first moving platform 33 to move backward.

When the first movable table 33 and the second movable table 34 move toward the front of the central cavity 4 at the same time, the second movable table 34 pushes the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves upward. At the same time, the first movable table 33 pulls the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves downward. At this time, the lifting block 17 at the front end of the workbench 3 protrudes from the workbench 3, and the workbench 3 The lifting block 17 at the tail end of the platform 3 shrinks into the central cavity 4. When the first movable platform 33 and the second movable platform 34 can move toward the rear of the central cavity 4 at the same time, the first movable platform 33 pushes the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves upward. At the same time, the second movable platform 34 pulls the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves downward. At this time, the lifting block 17 at the front end of the workbench 3 shrinks into the central cavity 4, and the lifting block 17 at the tail end of the workbench 3 protrudes from the workbench 3. The two modes of the obstacle mechanism 8 can be alternately reflected on the surface of the workbench 3, and obstacles can be set within the range of the floor scrubber.

[0021] The driving mechanism 7 includes a stepper motor 19 and a third gear 20. The output end of the stepper motor 19 is connected to the first gear 9.

When the third gear 20 rotates, the first push rack 21 can move inside the bottom cavity 5. When the third gear 20 rotates counterclockwise, the first push rack 21 will move toward the front of the bottom cavity 5. At this time, the first push rack 21 can push the extension rod 25 toward the inside of the reversing table 2. At this time, the second push rack 24 on the inner wall of the frame-type push rack 23 can drive the fourth gear 26 to rotate. When the floor scrubber is at the top of the turntable 28, the frame-type push rack 23 drives the fourth gear 26 to rotate 180 degrees, thereby realizing the U-turn operation of the floor scrubber, which is convenient for repeated testing of the floor scrubber.

[0023] The top of the turntable 28 is level with the top of the reversing platform 2, ensuring that the scrubber can smoothly move from the workbench 3 to the reversing platform 2 and the surface of the turntable 28. A limit frame 30 is provided on the top of the reversing platform 2. The limit frame 30 is located on the side of the turntable 28 and can block the outer side of the turntable 28 to play a limiting role. A limit ring 29 is provided on the outer surface of the turntable 28. The limit ring 29 is movably connected to the reversing platform 2 to ensure the stability of the turntable 28 when rotating.

[0024] An inclined plate 31 is provided on one side of the main platform 1 away from the reversing platform 2 . Both ends of the inclined plate 31 are connected with protruding blocks 32 through a rotating shaft. The other ends of the two protruding blocks 32 are fixedly connected to the workbench 3 . The floor scrubber can be moved to the surface of the workbench 3 through the inclined plate 31 .

[0025] Support frames are fixedly installed at the four end corners of the top of the main platform 1, and the top of the support frame is fixedly connected to the workbench 3 to enhance the stability of the connection between the main platform 1 and the workbench 3. A railing is installed on the side of the workbench 3 to protect the floor scrubber and prevent the floor scrubber from tipping over and falling.

[0026] Working principle: First, the scrubber can be moved to the surface of the workbench 3 through the inclined plate 31, and then the stepper motor 19 drives the first gear 9 to rotate. Since the first gear 9 is meshed with the second gear 10, when the first gear 9 rotates, the second gear 10 will also rotate, and the first gear 9 and the second gear 10 rotate in opposite directions. When the first gear 9 and the second gear 10 rotate, the first sector rack 11 and the second sector rack 12 at the top thereof will also rotate, so that the first sector rack 11 and the second sector rack 12 can control the first moving platform 33 and the second moving platform 34 in turn. When the first gear 9 rotates clockwise and the second gear 10 rotates counterclockwise, the first gear 9 rotates clockwise and the second gear 10 rotates counterclockwise. The sector rack 11 drives the first moving platform 33 to move forward, and the second sector rack 12 drives the second moving platform 34 to move forward. The first moving platform 33 and the second moving platform 34 can move toward the front of the central cavity 4 at the same time, and the second moving platform 34 pushes the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves upward. At the same time, the first moving platform 33 pulls the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves downward. At this time, the lifting block 17 at the front end of the workbench 3 protrudes from the workbench 3, and the lifting block 17 at the tail end of the workbench 3 shrinks into the central cavity 4. Then, after rotating a certain angle, the directions of the first sector rack 11 and the second sector rack 12 are swapped. At this time, the first sector rack 11 is rotated at a fixed angle. The fan-shaped rack 11 drives the second moving platform 34 to move backward, and the second fan-shaped rack 12 drives the first moving platform 33 to move backward. The first moving platform 33 and the second moving platform 34 can move toward the rear of the central cavity 4 at the same time, and the first moving platform 33 pushes the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves upward, and at the same time, the second moving platform 34 pulls the lifting block 17 under the action of the connecting rod 16, so that the lifting block 17 moves downward. At this time, the lifting block 17 at the front end of the workbench 3 is retracted into the central cavity 4, and the lifting block 17 at the rear end of the workbench 3 protrudes from the workbench 3, that is, when the first gear 9 rotates, the first moving platform 33 and the second moving platform 34 can do reciprocating motion inside the central cavity 4, and the obstacle mechanism The two modes of 8 can be alternately embodied on the surface of the workbench 3, and obstacles can be set within the range of the floor scrubber. Finally, after the floor scrubber moves from the workbench 3 to the surface of the turntable 28, when the stepper motor 19 drives the third gear 20 to rotate counterclockwise, the first push rack 21 will move toward the front of the bottom cavity 5. At this time, the first push rack 21 can push the extension rod 25 toward the inside of the reversing table 2. At this time, the second push rack 24 on the inner wall of the frame-type push rack 23 can drive the fourth gear 26 to rotate. When the floor scrubber is at the top of the turntable 28, the frame-type push rack 23 drives the fourth gear 26 to rotate 180 degrees, thereby realizing the U-turn operation of the floor scrubber, which is convenient for repeated testing of the floor scrubber.
