Description

Technical Field

[0001] The invention relates to the technical field of construction engineering equipment, in particular to a pouring device for a highway roadbed and a use method thereof. Background Art

[0002] The roadbed is the foundation of the track or road surface. It is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track and locomotive vehicles or road surface and traffic loads, while transferring and diffusing the loads deep into the foundation. In the longitudinal section, the roadbed must ensure the required elevation of the line; in the plane, the roadbed is connected with bridges and tunnels to form a complete through line. In civil engineering, the roadbed occupies an important position in terms of construction quantity, land area and investment.

[0003] When pouring the roadbed, concrete is often poured in part of the roadbed and then leveled by leveling equipment. However, since the concrete is poured in part of the roadbed, the pouring height may be uneven. During the leveling process, depressions may appear in some areas, and the depressions that appear during the leveling process need to be filled a second time, thus affecting the construction efficiency. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a pouring device for a highway roadbed, including a leveling mechanism, the leveling mechanism also includes a pouring vehicle, the front and back of the pouring vehicle are fixedly connected to a connecting frame 1, the inner walls of the two connecting frames 1 are rotatably connected to a pressing wheel, and also includes: The cleaning mechanism includes a fixed block 2 fixedly connected to the bottom of the connecting frame 1, a connecting block fixedly connected to the front of the front connecting frame 1, a rotating brush is arranged at the side wall of the casting vehicle, and the outer wall of the rotating brush is rotatably connected to the inner wall of the fixed block 2; The jet mechanism comprises a fixed frame fixedly connected to a side wall of the connecting frame, an oil pipeline is connected through the top of the fixed frame, a piston rod is slidably connected to the inner wall of the oil pipeline, and hydraulic oil is arranged on the inner wall of the oil pipeline.

[0005] Preferably, the leveling mechanism further comprises a roadbed frame arranged at the bottom of the pouring vehicle, an inclined rotating rod is fixedly connected to the outer wall of the pressure wheel, a fixed block is fixedly connected to the bottom of the two connecting frames, and a sliding rod is slidably connected to the inner wall of the two fixed blocks; Among them, an extension frame is fixedly connected to the front of the front connecting frame, the outer wall of the sliding rod is slidably connected to the inner wall of the extension frame, and a return spring is fixedly connected to the side wall of the sliding rod, and one side wall of the return spring is fixedly connected to the side wall of the extension frame. The staff drives the casting vehicle to the constructed roadbed frame, and the casting vehicle drives on the roadbed frame to cast the concrete in the casting vehicle on the roadbed frame through the discharge pipe. The movement of the casting vehicle will also drive the connecting frame to move, so that the pressure wheel moves to flatten the concrete. When the pressure wheel contacts the concrete, it is affected by the friction force and can rotate by itself, driving the inclined rotating rod to rotate. The inclined rotating rod will contact the sliding rod during the rotation process.

[0006] Preferably, the leveling mechanism further comprises a fixing ring fixedly connected to the outer wall of the sliding rod 1, a sliding frame 1 is arranged on the side wall of the pressure wheel, the inner wall of the sliding frame 1 is slidably connected to the outer wall of the sliding rod 1, and the top of the connecting frame 1 is slidably connected to the connecting frame 2; Among them, a sliding plate is provided on the top of the sliding frame one. Since the contact surfaces of the inclined rotating rod and the sliding rod one are both inclined surfaces, the sliding rod one will be squeezed and move away from the inclined rotating rod, driving the sliding frame one to move through the fixed ring, and at the same time squeezing the return spring one to allow the return spring one to accumulate rebound force. When the sliding rod one is separated from the inclined rotating rod, the rebound force of the return spring one will be released, driving the sliding frame one to return to its original position. As the inclined rotating rod continues to rotate, the sliding frame one can flatten the concrete poured by the pouring vehicle.

[0007] Preferably, the leveling mechanism further comprises two spring return rods fixedly connected to the top of the sliding frame 1, the outer walls of the two spring return rods are slidably connected to the inner wall of the sliding plate, the front and back sides of the sliding plate are fixedly connected to the sliding rod 2, and the inner wall of the connecting frame 2 is slidably connected to the outer wall of the sliding rod 2; When the sliding plate is lifted up, the sliding plate is lifted up and the spring on the spring reset rod is pulled to accumulate rebound force. When the sliding plate is lifted up, the sliding plate is lifted up and the rebound force of the spring reset rod is released to make the sliding plate shake and drive the sliding plate to shake in the concrete. The sliding plate can be flattened by the lateral movement of the sliding plate to make the concrete height uniform. Then, the concrete can be moved in a small range in conjunction with the shaking of the sliding plate to fill the irregular depressions on the concrete surface. Finally, the concrete can be flattened by the pressing wheel to avoid the possibility of depressions in the roadbed in some areas during the leveling process, thereby ensuring the flatness of the roadbed surface, reducing the time for secondary adjustment and speeding up the construction efficiency.

[0008] Preferably, the cleaning mechanism also includes a spring block fixedly connected to the side wall of the rotating brush, a connecting plate fixedly connected to the side wall of the sliding rod 1, a fixed frame fixedly connected to the front of the front connecting frame 1, and a rotating frame rotatably connected to the outer wall of the fixed frame.

[0009] The cleaning mechanism also includes a sliding frame 2 slidably connected to the inner wall of the rotating frame, the top of the sliding frame 2 is fixedly connected to a limiting block, the outer wall of the limiting block is slidably connected to the inner wall of the fixed frame, and the side wall of the connecting plate is slidably connected to the inner wall of the rotating frame. The force of the movement of the sliding rod 1 will also drive the connecting plate to move when the sliding rod 1 is away from the inclined rotating rod, so that the connecting plate slides in the rotating frame, pushing the rotating frame to rotate, thereby pushing the sliding frame 2 to move. When the sliding frame 2 moves to contact the spring block, it will push the spring block to rotate, drive the rotating brush to rotate, and allow the spring block to accumulate rebound force. When the sliding rod 1 is separated from the inclined rotating rod, the connecting plate will return to its position, drive the rotating frame to return to its position, and allow the sliding frame 2 to return and separate from the spring block. At this time, the rebound force of the spring block will be released, causing the spring block to swing back and forth.

[0010] Preferably, the jet mechanism further comprises a piston rod 2 slidably connected to the inner wall of the oil delivery pipe, a spring plate slidably connected to the inner wall of the fixed frame, a guide plate fixedly connected to the bottom of the fixed frame, and a spring rotating plate rotatably connected to the inner wall of the fixed frame; Among them, a pushing block is fixedly connected to the bottom of the spring plate, and a pushing rod is fixedly connected to the top of the spring plate. The force of the movement of the sliding frame 2 will also drive the limit block to move when the sliding frame 2 moves, thereby pushing the piston rod 2 to move. Since there is hydraulic oil inside the oil pipeline, the hydraulic oil inside the oil pipeline will be squeezed when the piston rod 2 moves, and the squeezed hydraulic oil will push the piston rod 1 to move, thereby pushing the spring plate down. The movement of the spring plate will squeeze the gas inside the fixed frame. At this time, the squeezed gas will be blocked by the spring rotating plate, allowing the gas to generate high pressure.

[0011] Preferably, the jet mechanism further comprises a concave-convex plate fixedly connected to the outer wall of the push rod, the side walls of the two connecting frames 1 are fixedly connected to the fixed blocks 3, the side wall of the sliding frame 1 is provided with an extrusion plate, and the outer wall of the extrusion plate is rotatably connected to the inner wall of the fixed block 3; Among them, a push plate is fixedly connected to the outer wall of the extrusion plate, and a reset spring is fixedly connected to the side wall of the push plate. The side wall of the push plate is slidably connected to the side wall of the concave-convex plate. When the spring plate descends, it will also drive the push rod to descend. When the push rod descends, it will contact the extrusion plate, push the extrusion plate to rotate, and let the left side of the extrusion plate contact the pressure wheel, such as: Fig. 9 As shown, the bottom of the extrusion plate will also contact the rotating brush. At the same time, the descent of the push rod will also drive the concave-convex plate to descend. When the concave-convex plate moves, the convex position of the concave-convex plate will push the push plate to move toward the inclined rotating rod.

[0012] A method for using a pouring device for a highway roadbed comprises the following steps: S1: leveling the poured concrete; S2: moderate shaking in concrete; S3: Flatten the concrete.

[0013] The present invention has the following beneficial effects: (1) When the present invention is used, a worker drives a pouring vehicle to the constructed roadbed frame, and the pouring vehicle drives on the roadbed frame to pour the concrete in the pouring vehicle onto the roadbed frame through the discharge pipe. The movement of the pouring vehicle will also drive the connecting frame 1 to move, so that the pressing wheel moves to flatten the concrete. When the pressing wheel contacts the concrete, it is affected by the friction force and can rotate by itself, driving the inclined rotating rod to rotate. The inclined rotating rod will contact the sliding rod 1 during the rotation process. Since the contact surfaces of the inclined rotating rod and the sliding rod 1 are both inclined surfaces, the sliding rod 1 will be squeezed and move away from the inclined rotating rod, driving the sliding frame 1 to move through the fixed ring, and at the same time squeezing the return spring 1, allowing the return spring 1 to accumulate rebound force. When the sliding rod 1 is separated from the inclined rotating rod, the rebound force of the return spring 1 will be released, driving the sliding frame 1 to return to its original position. As the inclined rotating rod continues to rotate, the sliding frame 1 can be The concrete poured by the pouring vehicle is flattened. At the same time, after the inclined rotating rod is separated from the sliding rod one, the inclined rotating rod will contact the connecting frame two, lift up the connecting frame two, pull the sliding rod two to rise, drive the sliding plate to rise, pull the spring on the spring reset rod, and let the spring accumulate rebound force. When the inclined rotating rod is separated from the connecting frame two, the sliding plate will fall quickly, and the rebound force of the spring reset rod will be released, causing the sliding plate to vibrate, driving the sliding frame one to vibrate in the concrete. Through the lateral movement of the sliding frame one, concrete with inconsistent heights can be flattened to make the concrete height uniform, and then the sliding frame one is vibrated to make the concrete move in a small range to fill the irregular depressions on the concrete surface, and finally the concrete is flattened by the pressing wheel to avoid the possibility of depressions in some areas of the roadbed during the leveling process, thereby ensuring the flatness of the roadbed surface, reducing the time for secondary adjustment, and speeding up construction efficiency.

[0014] When the sliding rod 1 is separated from the inclined rotating rod, the connecting plate will return to its original position, driving the rotating frame to return to its original position, so that the sliding frame 2 will return to its original position and separate from the spring block. At this time, the spring block's rebound force will be released, causing the spring block to swing back and forth, driving the rotating brush to swing back and forth, and at the same time, the sliding frame 1 will also shake up and down, so that the swinging rotating brush cooperates with the shaking sliding frame 1 to remove the concrete attached to the surface of the sliding frame 1, preventing excessive concrete from being attached to the surface of the sliding frame 1, resulting in the surface of the sliding frame 1 being not smooth, which may cause the concrete leveling surface to appear wavy or uneven, affecting the leveling effect, and ensuring the stability of the sliding frame 1 during long-term operation.

[0015] (3) The present invention utilizes the force of the movement of the sliding frame 2. When the sliding frame 2 moves, it will also drive the limit block to move, pushing the piston rod 2 to move. Since there is hydraulic oil inside the oil pipeline, the piston rod 2 will squeeze the hydraulic oil inside the oil pipeline when it moves. The squeezed hydraulic oil will push the piston rod 1 to move, pushing the spring plate down. The movement of the spring plate will squeeze the gas inside the fixed frame. At this time, the squeezed gas will be blocked by the spring rotating plate, causing the gas to generate high pressure. As the spring plate continues to move, it will drive the push block to contact the spring rotating plate, pushing the spring rotating plate to rotate, allowing the squeezed gas to be guided by the guide plate and sprayed toward the rotating brush, preventing too much concrete from adhering to the surface of the rotating brush, which may cause the concrete to adhere to the sliding frame 1 again, affecting the cleaning effect of the rotating brush.

[0016] (4) The present invention utilizes the force of the spring plate to move. When the spring plate descends, it also drives the push rod to descend. When the push rod descends, it contacts the extrusion plate, pushing the extrusion plate to rotate, so that the left side of the extrusion plate contacts the pressure wheel, such as: Fig. 9 As shown, the bottom of the extrusion plate will also contact the rotating brush. At the same time, the descent of the push rod will also drive the concave-convex plate to descend. When the concave-convex plate moves, the convex position of the concave-convex plate will push the push plate to move in the direction of the inclined rotating rod, drive the extrusion plate to move, pull the second reset spring to move, and allow the second reset spring to accumulate rebound force. When the extrusion plate moves, the concrete attached to the surface of the pressing wheel can be quickly cleaned in coordination with the rotation of the pressing wheel to prevent excessive concrete from being attached to the surface of the pressing wheel, which affects the smoothness of the concrete surface after flattening. In addition, when the extrusion plate moves, since the bottom of the extrusion plate has a groove, the rotating brush will fluctuate, scattering the concrete attached to the rotating brush. In coordination with the ejected gas, the rotating brush can be cleaned more thoroughly, thereby enhancing the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] For example, see Figure 1 - Figure 6 The present invention is a pouring device for a highway roadbed, comprising a leveling mechanism 1, the leveling mechanism 1 also comprising a pouring vehicle 101, the front and back of the pouring vehicle 101 are fixedly connected with a connecting frame 102, the inner walls of the two connecting frames 102 are rotatably connected with a pressing wheel 103, and further comprising: The cleaning mechanism 2 includes a fixed block 201 fixedly connected to the bottom of the connecting frame 102, a connecting block 202 is fixedly connected to the front of the front connecting frame 102, a rotating brush 203 is arranged at the side wall of the casting vehicle 101, and the outer wall of the rotating brush 203 is rotatably connected to the inner wall of the fixed block 201; The jet mechanism 3 includes a fixed frame 301 fixedly connected to the side wall of the connecting frame 102, an oil pipeline 302 is connected to the top of the fixed frame 301, a piston rod 303 is slidably connected to the inner wall of the oil pipeline 302, and hydraulic oil is provided on the inner wall of the oil pipeline 302.

[0022] The leveling mechanism 1 also includes a roadbed frame 104 arranged at the bottom of the pouring vehicle 101, a bevel rotating rod 105 is fixedly connected to the outer wall of the pressure wheel 103, a fixed block 106 is fixedly connected to the bottom of the two connecting frames 102, and a sliding rod 107 is slidably connected to the inner wall of the two fixed blocks 106; Among them, the front side of the front connecting frame 102 is fixedly connected with an extension frame 108, the outer wall of the sliding rod 107 is slidably connected with the inner wall of the extension frame 108, the side wall of the sliding rod 107 is fixedly connected with a return spring 109, and the side wall of the return spring 109 is fixedly connected with the side wall of the extension frame 108. The staff drives the pouring vehicle 101 to the constructed roadbed frame 104, and the pouring vehicle 101 travels on the roadbed frame 104 to pour the concrete in the pouring vehicle 101 on the roadbed frame 104 through the discharge pipe. The movement of the pouring vehicle 101 will also drive the connecting frame 102 to move, so that the pressure wheel 103 moves to flatten the concrete. When the pressure wheel 103 contacts the concrete, it is affected by the friction force and the pressure wheel 103 can rotate by itself, driving the inclined rotating rod 105 to rotate. The inclined rotating rod 105 will contact the sliding rod 107 during the rotation process.

[0023] The leveling mechanism 1 further includes a fixing ring 110 fixedly connected to the outer wall of the sliding rod 107, a sliding frame 111 is provided on the side wall of the pressure wheel 103, the inner wall of the sliding frame 111 is slidably connected to the outer wall of the sliding rod 107, and a connecting frame 2 112 is slidably connected to the top of the connecting frame 102; Among them, a sliding plate 113 is arranged on the top of the sliding frame 111. Since the contact surfaces of the inclined rotating rod 105 and the sliding rod 107 are both inclined surfaces, the sliding rod 107 will be squeezed and away from the inclined rotating rod 105, and the sliding frame 111 will be driven to move through the fixing ring 110, and at the same time, the reset spring 109 will be squeezed to allow the reset spring 109 to accumulate resilience. When the sliding rod 107 is separated from the inclined rotating rod 105, the resilience of the reset spring 109 will be released, driving the sliding frame 111 to return to its original position. With the continuous rotation of the inclined rotating rod 105, the sliding frame 111 can flatten the concrete poured by the pouring vehicle 101.

[0024] The leveling mechanism 1 also includes two spring return rods 114 fixedly connected to the top of the sliding frame 111, the outer walls of the two spring return rods 114 are slidably connected to the inner wall of the sliding plate 113, the front and back of the sliding plate 113 are fixedly connected to the second sliding rod 115, and the inner wall of the connecting frame 112 is slidably connected to the outer wall of the second sliding rod 115; The inner walls of the two connecting frames 102 are provided with sliding grooves 116, and the outer walls of the two sliding rods 115 are slidably connected with the inner walls of the sliding grooves 116.

When the inclined rotating rod 105 is separated from the connecting frame 2 112, the sliding plate 113 will fall quickly. The spring return rod 114 will release its resilience, causing the sliding plate 113 to vibrate, driving the sliding frame 111 to vibrate in the concrete. The sliding frame 111 can move laterally to level the concrete with inconsistent heights, making the concrete height uniform. The sliding frame 111 can then vibrate to move the concrete in a small range, filling up irregular depressions on the concrete surface. Finally, the pressing wheel 103 can flatten the concrete, avoiding depressions in some areas of the roadbed during the leveling process, thereby ensuring the flatness of the roadbed surface, reducing the time for secondary adjustment, and speeding up construction efficiency.

[0025] For example 2, please refer to Figure 7 - Fig.14 The present invention is a pouring device for a highway roadbed. On the basis of the first embodiment, the cleaning mechanism 2 also includes a spring block 204 fixedly connected to the side wall of the rotating brush 203, a connecting plate 205 fixedly connected to the side wall of the sliding rod 107, a fixed frame 206 fixedly connected to the front of the front connecting frame 102, and a rotating frame 207 rotatably connected to the outer wall of the fixed frame 206.

The outer wall of the limit block 209 is slidably connected to the inner wall of the fixed frame 206, and the side wall of the connecting plate 205 is slidably connected to the inner wall of the rotating frame 207. The force of the sliding rod 107 moving will also drive the connecting plate 205 to move when the sliding rod 107 moves away from the inclined rotating rod 105, so that the connecting plate 205 slides in the rotating frame 207, pushing The rotating frame 207 rotates, thereby pushing the second sliding frame 208 to move. When the second sliding frame 208 moves to contact the spring block 204, it will push the spring block 204 to rotate, driving the rotating brush 203 to rotate, allowing the spring block 204 to accumulate resilience. When the sliding rod 107 is separated from the inclined rotating rod 105, the connecting plate 205 will return to its position, driving the rotating frame 207 to return to its position, allowing the second sliding frame 208 to return to its position and separate from the spring block 204. At this time, the resilience of the spring block 204 will be released, causing the spring block 204 to swing back and forth.

[0027] The jet mechanism 3 also includes a piston rod 304 slidably connected to the inner wall of the oil delivery pipe 302, a spring plate 305 slidably connected to the inner wall of the fixed frame 301, a guide plate 307 fixedly connected to the bottom of the fixed frame 301, and a spring rotating plate 306 rotatably connected to the inner wall of the fixed frame 301; Among them, the bottom of the spring plate 305 is fixedly connected with a pushing block 308, and the top of the spring plate 305 is fixedly connected with a pushing rod 309. By utilizing the force of the movement of the sliding frame 208, when the sliding frame 208 moves, it will also drive the limit block 209 to move, pushing the piston rod 2 304 to move. Since there is hydraulic oil inside the oil pipeline 302, the hydraulic oil inside the oil pipeline 302 will be squeezed when the piston rod 2 304 moves. The squeezed hydraulic oil will push the piston rod 1 303 to move, pushing the spring plate 305 to descend. The movement of the spring plate 305 will squeeze the gas inside the fixed frame 301. At this time, the squeezed gas will be blocked by the spring rotating plate 306, allowing the gas to generate high pressure.

The side wall of the push plate 313 is slidably connected with the side wall of the concave-convex plate 310. By utilizing the force of the movement of the spring plate 305, when the spring plate 305 descends, it will also drive the push rod 309 to descend. When the push rod 309 descends, it will contact the extrusion plate 312, push the extrusion plate 312 to rotate, and let the left side of the extrusion plate 312 contact the pressure wheel 103, such as: Fig. 9 As shown, the bottom of the squeezing plate 312 will also contact the rotating brush 203. At the same time, the descent of the push rod 309 will also drive the concave-convex plate 310 to descend. When the concave-convex plate 310 moves, the convex position of the concave-convex plate 310 will push the push plate 313 to move toward the inclined rotating rod 105.

[0029] The method for using the pouring device for highway roadbed comprises the following steps: S1: leveling the poured concrete; S2: moderate shaking in concrete; S3: Flatten the concrete.

[0030] A specific application of this embodiment is: when the present invention is used, the staff drives the pouring vehicle 101 to the constructed roadbed frame 104, and the pouring vehicle 101 drives on the roadbed frame 104 to pour the concrete in the pouring vehicle 101 on the roadbed frame 104 through the discharge pipe. The movement of the pouring vehicle 101 will also drive the connecting frame 102 to move, so that the pressing wheel 103 moves to flatten the concrete. When the pressing wheel 103 contacts the concrete, it is affected by the friction force and can rotate by itself, driving the inclined rotating rod When the inclined rotating rod 105 rotates, the inclined rotating rod 105 will contact the sliding rod 107 during the rotation process. Since the contact surfaces of the inclined rotating rod 105 and the sliding rod 107 are both inclined surfaces, the sliding rod 107 will be squeezed and move away from the inclined rotating rod 105, and the sliding frame 111 will be driven to move through the fixing ring 110, and the reset spring 109 will be squeezed at the same time, so that the reset spring 109 accumulates the resilience. When the sliding rod 107 is separated from the inclined rotating rod 105, the resilience of the reset spring 109 will be released, driving the sliding frame 111 When the inclined rotating rod 105 is separated from the sliding rod 107, the inclined rotating rod 105 will contact the second connecting frame 112, lift the second connecting frame 112, pull the second sliding rod 115 up, drive the sliding plate 113 up, pull the spring on the spring return rod 114, let the spring accumulate the rebound force, when the inclined rotating rod 105 is separated from the second connecting frame 112, the sliding plate 113 will It will fall down quickly, and the resilience of the spring return rod 114 will be released, causing the sliding plate 113 to shake, driving the sliding frame 111 to shake in the concrete. The lateral movement of the sliding frame 111 can flatten the concrete with inconsistent heights to make the concrete height uniform. Then, the shaking of the sliding frame 111 can make the concrete move in a small range to fill the irregular depressions on the concrete surface. Finally, the concrete is flattened by the pressing wheel 103 to avoid depressions in some areas of the roadbed during the leveling process, thereby ensuring the flatness of the roadbed surface. Secondly, when the sliding rod 107 is away from the inclined rotating rod 105, the connecting plate 205 will be driven to move, so that the connecting plate 205 slides in the rotating frame 207, pushing the rotating frame 207 to rotate, thereby pushing the sliding frame 208 to move. When the sliding frame 208 moves to contact the spring block 204, it will push the spring block 204 to rotate, driving the rotating brush 203 to rotate, allowing the spring block 204 to accumulate resilience. When the sliding rod 107 is separated from the inclined rotating rod 105, the connecting plate 205 will return to its original position, driving the rotating frame 207 to return to its original position, allowing the sliding frame 208 to return to its original position and contact the spring block 20 4, at which time the resilience of the spring block 204 is released, causing the spring block 204 to swing back and forth, driving the rotating brush 203 to swing back and forth, and at the same time the sliding frame 111 will also shake up and down, so that the swinging rotating brush 203 cooperates with the shaking sliding frame 111 to remove the concrete attached to the surface of the sliding frame 111, preventing excessive concrete from adhering to the surface of the sliding frame 111, resulting in the surface of the sliding frame 111 being not smooth, which may cause the concrete leveling surface to appear wavy or uneven, affecting the leveling effect, and ensuring the stability of the sliding frame 111 during long-term operation; Secondly, when the sliding frame 208 moves, it will also drive the limit block 209 to move, pushing the piston rod 204 to move. Since there is hydraulic oil inside the oil pipe 302, the piston rod 204 will squeeze the hydraulic oil inside the oil pipe 302 when it moves. The squeezed hydraulic oil will push the piston rod 1 303 to move, pushing the spring plate 305 to descend. The movement of the spring plate 305 will squeeze the gas inside the fixed frame 301. At this time, the squeezed gas will be blocked by the spring rotating plate 306, allowing the gas to generate high pressure. As the spring plate 305 continues to move, it will drive the pushing block 308 to contact the spring rotating plate 306, pushing the spring rotating plate 306 to rotate, allowing the squeezed gas to be guided by the guide plate 307 and sprayed toward the rotating brush 203, preventing too much concrete from adhering to the surface of the rotating brush 203, which may cause the concrete to adhere to the sliding frame 111 again, affecting the cleaning effect of the rotating brush 203; Secondly, when the spring plate 305 descends, it will also drive the push rod 309 to descend. When the push rod 309 descends, it will contact the extrusion plate 312, pushing the extrusion plate 312 to rotate, so that the left side of the extrusion plate 312 contacts the pressure wheel 103, such as: Fig. 9As shown, the bottom of the extrusion plate 312 will also contact the rotating brush 203. At the same time, the descent of the push rod 309 will also drive the concave-convex plate 310 to descend. When the concave-convex plate 310 moves, the convex position of the concave-convex plate 310 will push the push plate 313 to move toward the inclined rotating rod 105, drive the extrusion plate 312 to move, pull the return spring 214 to move, and let the return spring 214 accumulate resilience. When the extrusion plate 312 moves, in conjunction with the rotation of the pressing wheel 103, the concrete attached to the surface of the pressing wheel 103 can be quickly cleaned to prevent excessive concrete from being attached to the surface of the pressing wheel 103, affecting the smoothness of the concrete surface after flattening; in addition: when the extrusion plate 312 moves, due to the groove at the bottom of the extrusion plate 312, the rotating brush 203 will fluctuate, scatter the concrete attached to the rotating brush 203, and in conjunction with the ejected gas, the rotating brush 203 can be cleaned more cleanly, thereby enhancing the cleaning effect.
