Description

Technical Field

[0001] This invention relates to the field of measuring equipment technology, and in particular to a flatness testing device and method for industrial plant floor construction. Background Technology

[0002] The floor is the part of the ground floor room that comes into contact with the soil layer. It bears the load of the ground floor room and is required to have a certain strength and rigidity, as well as moisture-proof, waterproof, heat-insulating and wear-resistant properties. After the floor construction is completed, the flatness of the floor needs to be tested in order to ensure the quality of the floor and meet the requirements of subsequent construction.

[0003] Existing technologies still have some shortcomings in the process of detecting floor flatness:

[0004] 1. When testing the ground, the flatness testing device usually uses the testing probe to directly contact the ground for testing. However, since there is a lot of dust and gravel on the ground at the construction site, it affects the accuracy of the test. In addition, the contact between the testing probe and the ground can easily cause wear on the testing probe.

[0005] 2. In addition, the measurement process only measures the lowest and highest points, making it difficult to draw a data curve of the ground elevation undulation.

[0006] To address the aforementioned problems, this invention proposes a flatness testing device and method for industrial plant floor construction. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies, such as the easy wear and tear of the detection probe when in contact with the ground, the impact of dust and gravel on the ground on the detection accuracy, and the difficulty in plotting the data curve of the unevenness of the floor. Therefore, this invention proposes a flatness detection device and method for industrial plant floor construction.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A flatness testing device for industrial plant floor construction includes a vehicle body, a rectangular hole inside the vehicle body, a gas storage box inside the rectangular hole, a rotating groove on one side of the vehicle body, and a rotating plate inside the rotating groove.

[0010] The detection structure, set inside a rectangular hole, is used to simultaneously control the rotation of the gas storage tank and the rotating plate to detect the data curve of the elevation undulation of the ground.

[0011] The cleaning structure is located on the top of the vehicle body and to the left of the detection structure. It is used to clean the ground to prevent dust and stones from affecting the detection accuracy.

[0012] Four sets of movable structures are installed in pairs on both sides of the vehicle body to ensure smooth movement of the vehicle.

[0013] In one possible design, the detection structure includes two first rotating shafts rotatably connected to the inner walls of a rectangular hole, which are far apart from each other. The ends of the two first rotating shafts, close to each other, are fixedly connected to a gas storage tank. A second rotating shaft is rotatably connected within the rotating groove, and a rotating plate is fixed to the outer wall of the second rotating shaft. A first synchronous pulley is fixed to the outer wall of the first rotating shaft, and a second synchronous pulley is fixed to the outer wall of the second rotating shaft. The second synchronous pulley and the first synchronous pulley are connected by a synchronous belt. A red laser emitter and a first distance sensor are bolted to one side of the rotating plate. A motor (not shown in the figure) drives the second rotating shaft to rotate, causing the rotating plate to rotate 180°, exposing the red laser emitter and the first distance sensor. The second rotating shaft, through the cooperation of the first synchronous pulley, the synchronous belt, and the second synchronous pulley, causes the gas storage tank to rotate 90°, resulting in a vertical position for the gas storage tank and the piston rod. The first distance sensor can then measure the distance the vehicle has moved in real time, while the second distance sensor can detect ground undulation data at that distance, thus obtaining a ground elevation undulation data curve.

[0014] In one possible design, the detection structure further includes a piston plate that is sealed and slidably connected within the gas storage tank. A piston rod is bolted to the bottom of the piston plate, and the bottom end of the piston rod slides through the bottom inner wall of the gas storage tank and is welded to a movable seat. A second distance sensor is bolted to the top inner wall of the movable seat. The gas storage tank is filled with helium. When the gas storage tank is in a vertical position, because it is filled with compressed helium, the piston plate, piston rod, and movable seat move downwards under the action of the helium, allowing the roller to contact the ground. This enables the second distance sensor to accurately detect the vehicle during its movement.

[0015] In one possible design, the cleaning structure includes a sliding groove on the top of the vehicle body, within which a push plate is slidably connected. The vehicle body has multiple arc-shaped sliding grooves, each containing an arc-shaped plate. The tops of the arc-shaped plates extend into the sliding grooves. Multiple sliding blocks are slidably connected to the side of the push plate near a rectangular hole, and these blocks are rotatably connected to the tops of the arc-shaped plates. Multiple springs are fixed to the side of the push plate near the rectangular hole, with the other ends of the springs fixedly connected to the inner wall of one side of the sliding groove. Air gun nozzles are bolted to the bottom ends of the arc-shaped plates. A pull rope is provided on the side of the push plate near the rectangular hole, with the other end of the pull rope connected to the gas... The top of the storage box is fixedly connected, and the top of the gas storage box is equipped with a guide wheel for guiding the pull rope. When the gas storage box rotates, the gas storage box pulls the push plate to the left through the pull rope. The push plate pushes the arc plate to move through the sliding block. The arc plate drives the air gun nozzle to move from the arc-shaped groove to the bottom of the vehicle body. The small air pump (not shown in the figure) is started. The small air pump injects gas into the air gun nozzle through the hose. Then, during the movement of the vehicle body, the air gun nozzle can blow away the dust and stones on the ground. The multiple air gun nozzles correspond to the positions of the rollers and the second distance sensor, which ensures that the moving seat moves smoothly under the action of the rollers during the subsequent detection process and ensures the detection accuracy of the second distance sensor.

[0016] In one possible design, the moving structure includes a sleeve and a sliding rod, with the sleeve welded to one side of the vehicle body. The sliding rod is slidably connected inside the sleeve, and a screw for positioning the sliding rod is threaded onto the top of the sleeve. A support plate is welded to the end of the sliding rod away from the vehicle body, and an electric wheel is provided at the bottom of the support plate. By pulling the sliding rod and the support plate out of the sleeve and then fixing the sliding rod with the screw, the distance between the electric wheel and the vehicle body can be controlled, thereby making the vehicle body more stable when moving and preventing the gas storage tank from shaking during the testing process.

[0017] In one possible design, a third rotating shaft is rotatably connected to both sides of the movable base. A roller is bolted to the end of the third rotating shaft furthest from the movable base. A fourth rotating shaft is rotatably connected to both sides of the movable base. A cleaning cylinder is bolted to the end of the fourth rotating shaft furthest from the movable base, and the cleaning cylinder is used to clean the roller. A first sprocket and a second sprocket are respectively fixed to the outer walls of the third and fourth rotating shafts. The second sprocket and the first sprocket are connected by a chain drive. Multiple air gun nozzles correspond to the positions of the second distance sensor and the two rollers. During the rotation of the rollers, the third rotating shaft drives the cleaning cylinder to rotate through the cooperation of the first sprocket, the second sprocket, and the chain. The cleaning cylinder cleans the outer wall of the rollers, preventing dirt from adhering to the outer wall and affecting the accuracy of the second distance sensor.

[0018] In one possible design, a display screen is provided on one side of the top of the vehicle body. The display screen is electrically connected to a second distance sensor, a red laser emitter, and a first distance sensor. The data detected by the first and second distance sensors can be displayed on the display screen, allowing the user to clearly observe the data curve of the ground elevation undulation.

[0019] In one possible design, the diameter of the first sprocket is larger than the diameter of the second sprocket, and the diameter of the first synchronizing wheel is larger than the diameter of the second synchronizing wheel; when the third rotating shaft and the roller rotate, the cleaning cylinder can rotate faster, which facilitates the cleaning cylinder to clean the outer wall of the roller; when the second rotating shaft rotates 180°, the first rotating shaft can rotate 90°.

[0020] In one possible design, an infrared receiver and a baffle are bolted to the inner wall of the rectangular hole near the sliding groove. An infrared transmitter that cooperates with the infrared receiver is bolted to one side of the gas storage box, and the baffle is used to limit the gas storage box. The gas storage box and the piston rod are in a vertical position. The infrared receiver receives the infrared rays emitted by the infrared transmitter, which can ensure that the gas storage box rotates 90° and avoid the gas storage box rotation angle being inaccurate.

[0021] This application discloses a method for using a flatness testing device for industrial plant floor construction, comprising the following steps:

[0022] S1. Place the vehicle body in the area to be tested, pull out the slide bar and the support plate from the sleeve, and then fix the slide bar with screws. This allows control over the distance between the electric wheel and the vehicle body, making the vehicle body more stable when it moves and preventing the gas storage tank from shaking during the test.

[0023] S2. The second rotating shaft is driven by a motor to rotate, which in turn drives the rotating plate to rotate 180°. The red laser emitter and the first distance sensor are exposed. The second rotating shaft drives the gas storage box to rotate 90° through the cooperation of the first synchronous pulley, the synchronous belt and the second synchronous pulley. The gas storage box and the piston rod are in a vertical state. The infrared receiver receives the infrared light emitted by the infrared emitter, which can ensure that the gas storage box rotates 90° and avoid the gas storage box rotation angle being inaccurate. Since the gas storage box is filled with compressed helium, the piston plate, piston rod and moving seat move downward under the action of helium, which can make the roller contact the ground.

[0024] S4. Additionally, when the gas storage tank rotates, the gas storage tank pulls the push plate to the left via a pull rope. The push plate then moves the arc-shaped plate via a sliding block. The arc-shaped plate moves the air gun nozzle from the arc-shaped groove to the bottom of the vehicle body. The small air pump is then activated, injecting gas into the air gun nozzle through a hose. As the vehicle body moves, the air gun nozzle can blow away dust and stones on the ground. Furthermore, multiple air gun nozzles correspond to the positions of the rollers and the second distance sensor, ensuring that the moving seat moves smoothly under the action of the rollers during the subsequent detection process, thus ensuring the accuracy of the second distance sensor detection.

[0025] S5. During the rotation of the roller, the third shaft drives the cleaning cylinder to rotate through the cooperation of the first sprocket, the second sprocket and the chain. The cleaning cylinder can clean the outer wall of the roller to prevent dirt from adhering to the outer wall of the roller and affecting the detection accuracy of the second distance sensor.

[0026] S6. When the vehicle moves, the first distance sensor can measure the distance the vehicle moves, and the second distance sensor can detect the undulation of the ground when the vehicle moves. The data detected by the first and second distance sensors can clearly observe the ground elevation curve. The red laser emitted by the red laser emitter can serve as a warning to prevent unauthorized personnel from obstructing the distance measurement of the first distance sensor.

[0027] In this invention, the two first rotating shafts are fixedly connected to a gas storage tank at their close ends. A second rotating shaft is rotatably connected within the rotating groove. A first synchronous pulley and a second synchronous pulley are fixed to the outer walls of the first and second rotating shafts, respectively, and the second synchronous pulley and the first synchronous pulley are connected by a synchronous belt drive. A red laser emitter and a first distance sensor are fixed to one side of the rotating plate by bolts. The second rotating shaft drives the rotating plate to rotate 180°, and the gas storage tank to rotate 90°. The gas storage tank and the piston rod are in a vertical position. Then, the distance traveled by the vehicle body can be measured in real time by the first distance sensor, while the second distance sensor can detect the ground undulation data at this distance, thereby obtaining the ground elevation undulation data curve.

[0028] In this invention, a push plate is slidably connected in the sliding groove, and an arc plate is slidably connected in each of the multiple arc-shaped sliding grooves. One side of the push plate is rotatably connected to the top of the arc plate through a sliding block, and an air gun nozzle is fixed at the bottom of each of the multiple arc plates. The gas storage tank pulls the push plate to the left by a pull rope. The push plate pushes the arc plate and the air gun nozzle to move under the vehicle body. During the movement of the vehicle body, the air gun nozzle can blow away the dust and stones on the ground. The multiple air gun nozzles correspond to the positions of the rollers and the second distance sensor, respectively, to ensure that the moving seat moves smoothly under the action of the rollers during the subsequent detection process, thus ensuring the accuracy of the detection by the second distance sensor.

[0029] In this invention, a third rotating shaft is rotatably connected to both sides of the movable base, and a roller is fixed to one end of the third rotating shaft. A fourth rotating shaft is rotatably connected to both sides of the movable base, and a cleaning cylinder is fixed to one end of the fourth rotating shaft. A first sprocket and a second sprocket are respectively fixed to the outer walls of the third and fourth rotating shafts, and the second sprocket and the first sprocket are connected by a chain drive. During the rotation of the roller, the third rotating shaft drives the cleaning cylinder to rotate through the cooperation of the first sprocket, the second sprocket and the chain. The cleaning cylinder can clean the outer wall of the roller, preventing dirt from adhering to the outer wall of the roller and affecting the detection accuracy of the second distance sensor.

[0030] In this invention, a piston plate is slidably connected inside the gas storage tank. A piston rod is fixed to the bottom of the piston plate by bolts. A movable seat is welded to the bottom end of the piston rod. A second distance sensor is fixed to the top inner wall of the movable seat by bolts. The gas storage tank is filled with helium. When the gas storage tank is in a vertical position, because the gas storage tank is filled with compressed helium, the piston plate, piston rod, and movable seat move downward under the action of the helium, which allows the roller to contact the ground. Thus, during the movement of the vehicle body, the second distance sensor can accurately detect the movement.

[0031] In this invention, when the vehicle moves, the second distance sensor works in conjunction with the first distance sensor to monitor the ground undulation data and the distance the vehicle moves in real time, thereby obtaining the ground elevation undulation data curve. In addition, when the vehicle moves, the ground and the outer wall of the rollers can be cleaned to ensure that the monitoring by the second distance sensor and the first distance sensor makes the vehicle move smoothly and ensures the accuracy of the monitoring data.

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1

[0044] Reference Figures 1-8 A flatness testing device for industrial plant floor construction, which is used in the field of measuring equipment, includes a vehicle body 1, a rectangular hole 2 inside the vehicle body 1, a gas storage box 4 inside the rectangular hole 2, a rotating groove 11 on one side of the vehicle body 1, and a rotating plate 6 inside the rotating groove 11.

[0045] Reference Figure 2 , Figure 4 , Figure 5 A display screen is provided on one side of the top of the vehicle body 1. The display screen is electrically connected to the second distance sensor 15, the red laser emitter 9 and the first distance sensor 10. The data detected by the first distance sensor 10 and the second distance sensor 15 can be displayed on the display screen, allowing the user to clearly observe the data curve of the ground elevation undulation.

[0046] Reference Figure 3 and Figure 4 The system also includes a detection structure set within the rectangular hole 2, used to simultaneously control the rotation of the gas storage tank 4 and the rotating plate 6 to detect the data curve of the ground elevation undulation. The detection structure includes two first rotating shafts 3 rotatably connected to the inner walls of the rectangular hole 2, which are far apart from each other. The ends of the two first rotating shafts 3 that are close to each other are fixedly connected to the gas storage tank 4. A second rotating shaft 5 is rotatably connected within the rotating groove 11, and the rotating plate 6 is fixed to the outer wall of the second rotating shaft 5. A first synchronous pulley 7 is fixed to the outer wall of the first rotating shaft 3, and a second synchronous pulley 41 is fixed to the outer wall of the second rotating shaft 5. The second synchronous pulley 41 and the first synchronous pulley 7 are connected by a synchronous belt 8. One side of the rotating plate 6... A red laser emitter 9 and a first distance sensor 10 are fixed by bolts. A second rotating shaft 5 is driven to rotate by a motor (not shown in the figure). The second rotating shaft 5 drives the rotating plate 6 to rotate 180°, exposing the red laser emitter 9 and the first distance sensor 10. The second rotating shaft 5 drives the gas storage tank 4 to rotate 90° through the cooperation of the first synchronous pulley 7, the synchronous belt 8, and the second synchronous pulley 41. The gas storage tank 4 and the piston rod 13 are in a vertical state. Then, the distance of the vehicle body 1 can be measured in real time by the first distance sensor 10, and the ground undulation data can be detected at this distance by the second distance sensor 15, so as to obtain the ground elevation undulation data curve.

[0047] Reference Figure 3 and Figure 4 The detection structure also includes a piston plate 12 that is slidably connected in a sealed manner within the gas storage tank 4. A piston rod 13 is bolted to the bottom of the piston plate 12. The bottom end of the piston rod 13 slides through the bottom inner wall of the gas storage tank 4 and is welded to a movable seat 14. A second distance sensor 15 is bolted to the top inner wall of the movable seat 14. The gas storage tank 4 is filled with helium. When the gas storage tank 4 is in a vertical position, because the gas storage tank 4 is filled with compressed helium, the piston plate 12, piston rod 13, and movable seat 14 move downward under the action of the helium, which allows the roller 17 to contact the ground. Thus, during the movement of the vehicle body 1, the second distance sensor 15 can accurately perform detection.

[0048] Reference Figure 5 and Figure 6 The movable base 14 is rotatably connected to two sides of a third rotating shaft 16. A roller 17 is fixed to the end of the third rotating shaft 16 away from the movable base 14 by bolts. The movable base 14 is also rotatably connected to two sides of a fourth rotating shaft 18. A cleaning cylinder 19 is fixed to the end of the fourth rotating shaft 18 away from the movable base 14 by bolts. The cleaning cylinder 19 is used to clean the roller 17. A first sprocket 20 and a second sprocket 21 are fixed to the outer walls of the third rotating shaft 16 and the fourth rotating shaft 18, respectively. The second sprocket 21 and the first sprocket 20 are connected by a chain 22. Multiple air gun nozzles 29 are respectively positioned opposite the second distance sensor 15 and the two rollers 17. During the rotation of the roller 17, the third rotating shaft 16 drives the cleaning cylinder 19 to rotate through the cooperation of the first sprocket 20, the second sprocket 21 and the chain 22. The cleaning cylinder 19 can clean the outer wall of the roller 17, preventing dirt from adhering to the outer wall of the roller 17 and affecting the detection accuracy of the second distance sensor 15.

[0049] Reference Figure 4 and Figure 6 The diameter of the first sprocket 20 is greater than the diameter of the second sprocket 21, and the diameter of the first synchronous pulley 7 is greater than the diameter of the second synchronous pulley 41. When the third rotating shaft 16 and the roller 17 rotate, the cleaning cylinder 19 can rotate faster, which facilitates the cleaning cylinder 19 to clean the outer wall of the roller 17. When the second rotating shaft 5 rotates 180°, the first rotating shaft 3 can rotate 90°.

[0050] Reference Figure 3 and Figure 7The system also includes a cleaning structure located on the top of the vehicle body 1, positioned to the left of the detection structure. This structure cleans the ground to prevent dust and pebbles from affecting detection accuracy. The cleaning structure includes a sliding groove 23 on the top of the vehicle body 1, with a push plate 24 slidably connected within it. Multiple arc-shaped grooves 27 are located inside the vehicle body 1, each containing an arc-shaped plate 28. The tops of the arc-shaped plates 28 extend into the sliding grooves 23. Multiple sliding blocks 30 are slidably connected to the side of the push plate 24 near the rectangular hole 2, and these blocks are rotatably connected to the tops of the arc-shaped plates 28. Multiple springs 25 are fixed to the side of the push plate 24 near the rectangular hole 2, with the other ends of the springs 25 fixed to the inner wall of one side of the sliding groove 23. Air gun nozzles 29 are bolted to the bottom ends of the multiple arc-shaped plates 28. A pull rope 26 is provided on one side of the hole 2, and the other end of the pull rope 26 is fixedly connected to the top of the gas storage box 4. The top of the gas storage box 4 is provided with a guide wheel 39 for guiding the pull rope 26. When the gas storage box 4 rotates, the gas storage box 4 pulls the push plate 24 to the left through the pull rope 26. The push plate 24 pushes the arc plate 28 to move through the sliding block 30. The arc plate 28 drives the air gun nozzle 29 to move from the arc groove 27 to the bottom of the vehicle body 1. The small air pump (not shown in the figure) is started. The small air pump injects gas into the air gun nozzle 29 through the hose. Then, during the movement of the vehicle body 1, the air gun nozzle 29 can blow away the dust and stones on the ground. The multiple air gun nozzles 29 correspond to the positions of the roller 17 and the second distance sensor 15, respectively, to ensure that the moving seat 14 moves smoothly under the action of the roller 17 during the later detection process, and to ensure the detection accuracy of the second distance sensor 15.

[0051] Reference Figure 2 and Figure 8 The system also includes four sets of movable structures 31 set on both sides of the vehicle body 1 to make the vehicle body 1 move smoothly. The movable structure 31 includes a sleeve 32 and a slide rod 33. The sleeve 32 is welded to one side of the vehicle body 1, and the slide rod 33 is slidably connected inside the sleeve 32. The top of the sleeve 32 is threaded with a screw 35 for positioning the slide rod 33. The end of the slide rod 33 away from the vehicle body 1 is welded with a bearing plate 34, and the bottom of the bearing plate 34 is provided with an electric wheel 36. The slide rod 33 and the bearing plate 34 are pulled out from the sleeve 32, and then the slide rod 33 is fixed by the screw 35. This allows the distance between the electric wheel 36 and the vehicle body 1 to be controlled, so that the vehicle body 1 can be more stable when it moves, and the gas storage tank 4 can be prevented from shaking during the detection process.

[0052] Example 2

[0053] refer to Figure 9An improvement based on embodiment 1 is made as follows: an infrared receiver 37 and a baffle 40 are fixed to the inner wall of the rectangular hole 2 near the sliding groove 23 by bolts; an infrared emitter 38 that cooperates with the infrared receiver 37 is fixed to one side of the gas storage box 4 by bolts, and the baffle 40 is used to limit the gas storage box 4; the gas storage box 4 and the piston rod 13 are in a vertical state, and the infrared receiver 37 receives the infrared rays emitted by the infrared emitter 38, which can ensure that the gas storage box 4 rotates 90° and avoid the gas storage box 4 rotating too inaccurately.

[0054] A method for using a flatness testing device for industrial plant floor construction includes the following steps:

[0055] S1. Place the vehicle body 1 in the area to be tested, pull out the slide bar 33 and the support plate 34 from the sleeve 32, and then fix the slide bar 33 with screws 35. This will control the distance between the electric wheel 36 and the vehicle body 1, so that the vehicle body 1 can be more stable when it moves, and avoid the gas storage box 4 from shaking during the test.

[0056] S2. The second rotating shaft 5 is driven to rotate by a motor (not shown in the figure). The second rotating shaft 5 drives the rotating plate 6 to rotate 180°. The red laser emitter 9 and the first distance sensor 10 are exposed. The second rotating shaft 5 drives the gas storage box 4 to rotate 90° through the cooperation of the first synchronous pulley 7, the synchronous belt 8 and the second synchronous pulley 41. The gas storage box 4 and the piston rod 13 are in a vertical state. The infrared receiver 37 receives the infrared rays emitted by the infrared emitter 38, which can ensure that the gas storage box 4 rotates 90° and avoid the gas storage box 4 rotating angle not being accurate enough. Since the gas storage box 4 is filled with compressed helium, the piston plate 12, the piston rod 13 and the moving seat 14 move downward under the action of helium, which can make the roller 17 contact the ground.

[0057] S4. Additionally, when the gas storage tank 4 rotates, the gas storage tank 4 pulls the push plate 24 to the left via the pull rope 26. The push plate 24 pushes the arc plate 28 to move via the sliding block 30. The arc plate 28 drives the air gun nozzle 29 to move from the arc-shaped slide 27 to the bottom of the vehicle body 1. The small air pump (not shown in the figure) is activated. The small air pump injects gas into the air gun nozzle 29 through the hose. As the vehicle body 1 moves, the air gun nozzle 29 can blow away the dust and stones on the ground. The multiple air gun nozzles 29 correspond to the positions of the roller 17 and the second distance sensor 15, respectively, to ensure that the moving seat 14 moves smoothly under the action of the roller 17 during the subsequent detection process, thus ensuring the accuracy of the detection by the second distance sensor 15.

[0058] S5. During the rotation of the roller 17, the third rotating shaft 16 drives the cleaning cylinder 19 to rotate through the cooperation of the first sprocket 20, the second sprocket 21 and the chain 22. The cleaning cylinder 19 can clean the outer wall of the roller 17 to prevent dirt from adhering to the outer wall of the roller 17 and affecting the detection accuracy of the second distance sensor 15.

[0059] S6. When the vehicle body 1 moves, the distance moved by the first distance sensor 10 can be measured, and the distance moved by the second distance sensor 15 can be detected by the undulation of the ground when the vehicle body 1 moves. Thus, the data detected by the first distance sensor 10 and the second distance sensor 15 can clearly observe the data curve of the ground elevation undulation. In addition, the red laser emitted by the red laser emitter 9 can serve as a warning to prevent unauthorized personnel from obstructing the distance measurement of the first distance sensor 10.

S4. During the rotation of the roller (17), the third shaft (16) drives the cleaning cylinder (19) to rotate through the cooperation of the first sprocket (20), the second sprocket (21) and the chain (22).
