The traditional leveling device lacks intelligent adjustment function and cannot automatically adjust the concrete discharge volume according to the actual situation of the road surface. In the depressions of the road surface, if the concrete discharge volume is insufficient, the depressions cannot be effectively filled, resulting in the road surface flatness not meeting the standards; and in the raised parts of the road surface, if the concrete discharge volume is too much, it will cause excessive accumulation of concrete, which will also affect the flatness of the road surface.

[0013] The present invention also discloses a leveling method for permeable concrete pavement, which specifically comprises the following steps:

[0014] Step 1: Put concrete into the box, and the concrete in the box is transported to the guide rack through the pipeline. The servo motor is turned on to drive the drive shaft and the guide blade to rotate synchronously, so that the guide blade pushes the concrete to move during the rotation, drives the concrete to move to each discharge channel, and enters the collecting hopper;

[0015] Step 2: The concrete in the aggregate hopper is discharged through the discharge chute and transported to the discharge hopper through the conveying pipe, and then the concrete is laid on the road surface by the discharge hopper;

[0016] Step three, the moving wheels move on the road surface as the vehicle body moves, that is, on a smooth road section, the guide wheels are located in the middle position of the inclined end of the control plate, that is, half of the discharge trough is located in the aggregate hopper. When the road surface is concave or convex, the moving wheels drive the vertical rod, the control plate and the fixed frame to move upward or downward. When the road surface is concave, the moving wheels drive the vertical rod, the control plate and the fixed frame to move downward, so that the control plate cooperates with the guide wheels to push the sealing plate to the side away from the fixed frame, that is, the discharge trough is located in the aggregate hopper and is enlarged, so that the concrete discharge volume is increased to fill the concave part of the road surface. When the road surface is convex, the moving wheels drive the vertical rod, the control plate and the fixed frame to move upward, so that the control plate cooperates with the guide wheels to push the sealing plate to the side of the fixed frame, that is, the discharge trough is located in the aggregate hopper and is reduced, so that the concrete discharge volume is reduced.

[0017] Compared with the prior art, it has the following beneficial effects:

[0018] The adjustment parts set can automatically adjust the size of the discharge chute in the aggregate hopper according to the actual situation of the road surface, so as to accurately control the discharge volume of concrete. In the depressions of the road surface, the discharge chute is enlarged to increase the concrete discharge volume and fill the depressions; in the convex parts of the road surface, the discharge chute is reduced to reduce the concrete discharge volume and avoid excessive accumulation. This intelligent adjustment ensures the flatness of concrete laying and improves the construction quality; the servo motor drives the drive shaft and the guide blades to rotate synchronously, effectively pushing the concrete forward and guiding it into each discharge channel and finally into the aggregate hopper. This design enables the concrete to be laid efficiently and evenly on the dirt road, improves the laying efficiency of permeable concrete, and enhances the permeability and bearing capacity of the dirt road.

[0019] The movable wheels can move flexibly under different road conditions as the vehicle body moves. The design of structures such as vertical rods, control panels and fixed frames enables the leveling device to adapt to changes in different road surfaces. Whether it is depression or convexity, it can be dealt with through automatic adjustment, which enhances the applicability and flexibility of the device. The design of structures such as fixed seats, movable rods, and the first damping spring ensures the stability and balance of the sealing plate, so that the discharge trough can always be kept in the proper position. At the same time, the fixed installation of the cross bar enhances the stability of the overall structure and improves the safety and reliability of the device. The design of intelligent adjustment of discharge volume and efficient laying of permeable concrete helps to improve the overall quality of the road. The evenly laid concrete enhances the bearing capacity and durability of the road and reduces maintenance costs. At the same time, the application of permeable concrete helps to improve the drainage performance of the road, reduce water accumulation, and improve driving safety.

[0020] The cam is driven to rotate by the rotating rod, which in turn pushes the L-shaped frame and the knocking rod to knock on the outer wall of the aggregate hopper. This design effectively solves the problem of concrete adhering to the inner wall of the aggregate hopper and ensures the smooth discharge of concrete. This knocking action can prevent concrete blockage and improve discharge efficiency, thereby ensuring the continuity and efficiency of construction; the reciprocating knocking action of the knocking rod not only helps to discharge concrete, but also promotes the uniform distribution of concrete to a certain extent, reduces bubbles and voids, and improves the density and uniformity of concrete, which helps to improve the overall quality of concrete paving and ensure the strength and durability of the road surface; the drive shaft drives the rotating rod to rotate through the synchronous belt transmission, and then drives the eccentric wheel, mounting wheel, connecting frame and sliding rod to move back and forth up and down. This movement mode enables the lower pressure plate to continuously and evenly compact and level the laid concrete road surface. The reciprocating movement of the lower pressure plate enhances the compaction effect of the road surface and ensures the flatness and quality of the road surface. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: Combination Figure 1-Figure 9 As shown, the present invention provides a technical solution: a leveling device for permeable concrete pavement, comprising a vehicle body 1, a box body 2 is fixedly installed on the top of the vehicle body 1, the box body 2 is a large storage and transportation device, a loading box 3 is fixedly installed on the upper end of its inner cavity, the loading box 3 is a container for loading and storing concrete, and its bottom is connected to a leveling component 4 through a pipeline, the leveling component 4 is a device for paving permeable concrete on a dirt road, and it comprises a guide rack 41 fixedly installed inside the box body 2, the guide rack 41 is connected to the loading box 3 through a pipeline, so that the concrete in the box body 2 can be discharged into the guide rack 41 through the pipeline;

[0033] A row of discharge channels 45 are provided at the bottom of the guide frame 41, and a collecting hopper 46 is provided through the discharge channels 45. The collecting hopper 46 is a device for collecting and distributing concrete, and a sealing plate 411 is slidably connected thereon in a transverse direction. A discharge trough 412 for discharging concrete is provided on the surface of the sealing plate 411 to ensure that the concrete can be discharged smoothly. A guide wheel 414 is installed on one side of the sealing plate 411, and an adjusting member for controlling the size of the discharge trough 412 in the collecting hopper 46 is provided on one side of the guide wheel 414. The size of the discharge trough 412 in the collecting hopper 46 is controlled to control the discharge amount of concrete, thereby ensuring the laying quality of the concrete.

[0034] A conveying pipe 47 is provided at the bottom of the collecting hopper 46, and a discharging hopper 48 is provided at the bottom of the discharging pipe 47. The discharging hopper 48 is a device for conveying concrete from the collecting hopper 46 to the ground, so as to ensure that the concrete can be evenly laid on the dirt road;

[0035] A circular groove is provided in the inner cavity of the guide frame 41, and a driving shaft 43 is rotatably connected in the circular groove. Both ends of the driving shaft 43 pass through the guide frame 41 and extend to the outside, and a servo motor 42 fixedly mounted on the outer wall of the box body 2 is provided at one end. The servo motor 42 is a device for controlling the rotation of the driving shaft 43, which can accurately control the speed and direction of the driving shaft 43. A guide blade 44 fixedly mounted on the driving shaft 43 is provided in the circular groove. The guide blade 44 is a device for pushing concrete to move. The driving shaft 43 and the guide blade 44 are driven to rotate synchronously by turning on the servo motor 42. During the rotation process, the guide blade 44 pushes the concrete to move, drives the concrete to move into each discharge channel 45, and enters the collecting hopper 46 for subsequent concrete laying. In this way, the leveling component 4 can efficiently and evenly lay permeable concrete, thereby improving the permeability and bearing capacity of the dirt road.

[0036] Fixed seats 49 are fixedly installed on both sides of the surface of the collecting hopper 46, and moving rods 410 are slidably connected to these fixed seats 49. The two ends of the moving rod 410 are fixedly connected to the two ends of the sealing plate 411, ensuring the stability of the sealing plate 411. In addition, a first damping spring 413 is provided between the fixed seat 49 and the sealing plate 411. The first damping spring 413 provided on both sides enables the sealing plate 411 to be located in the center of the collecting hopper 46. This design ensures that half of the discharge trough 412 is located inside the collecting hopper 46, and the other half is located outside the collecting hopper 46, thereby achieving a balanced discharge effect.

[0037] The design of the adjustment member is also ingenious, including a vertical rod 415 slidably mounted on the box body 2 in the vertical direction, a moving wheel 417 is arranged at the bottom of the vertical rod 415, so as to flexibly move under different road conditions, a control board 416 is fixedly connected to the top of the vertical rod 415, one side of the control board 416 slides in close contact with the guide wheel 414, ensuring the flexible adjustment of the control board 416, and a fixed frame 418 is fixedly connected to the other side, and a tilted end is arranged on the side of the control board 416 close to the guide wheel 414 to adapt to different road conditions, a cross bar 419 is slidably connected to the fixed frame 418, and the cross bar 419 is fixedly mounted on the box body 2, ensuring the stability of the overall structure, and the moving wheel 417 moves on the road surface as the vehicle body 1 moves, so that the entire device can adapt to different road conditions;

[0038] When on a smooth road section, the guide wheel 414 is located in the middle of the inclined end of the control plate 416. At this time, half of the discharge trough 412 is located in the collecting hopper 46, and the other half is located outside the collecting hopper 46, so that the uniform discharge of concrete is maintained. When the road surface is concave or convex, the moving wheel 417 drives the vertical rod 415, the control plate 416 and the fixed frame 418 to move upward or downward to adapt to the changes in the road surface. When the road surface is concave, the moving wheel 417 drives the vertical rod 415, the control plate 416 and the fixed frame 418 to move downward, so that the control plate 416 cooperates with the guide wheel 414 to push the sealing plate 411 to move away from the fixed frame 418, so that the discharge trough 412 is located in the collecting hopper 46. As the volume inside the hopper 46 increases, the amount of concrete discharged increases accordingly, which is used to fill the depressions in the road surface and ensure the flatness of the concrete paving. On the contrary, when a bulge appears on the road surface, the moving wheel 417 drives the vertical rod 415, the control board 416, and the fixed frame 418 to move upward, so that the control board 416 cooperates with the guide wheel 414 to push the sealing plate 411 to move toward the side of the fixed frame 418, that is, the discharge trough 412 located in the collecting hopper 46 is reduced, and the amount of concrete discharged is reduced accordingly, thereby avoiding excessive accumulation of concrete at the bulges of the road surface. In this way, the leveling device can automatically adjust the discharge volume according to the actual situation of the road surface to ensure the flatness of the concrete paving, thereby improving the construction quality and efficiency.

[0039] In the embodiment of the present invention, the servo motor 42 is started to drive the driving shaft 43 to rotate, which drives the guide blades 44 to rotate synchronously. During the rotation of the guide blades 44, they will effectively push the concrete forward, thereby guiding the concrete into each discharge channel 45. These discharge channels 45 transport the concrete to the collecting hopper 46 to prepare for the subsequent concrete paving work. At the same time, the moving wheel 417 moves on the road surface as the vehicle body 1 moves. When driving on a smooth road section, the guide wheel 414 is located in the middle position of the inclined end of the control board 416 to ensure that half of the discharge trough 412 is located in the collecting hopper 46. However, when the road surface is concave or convex, the moving wheel 417 will drive the vertical rod 415, the control board 416 and the fixed frame 418 to move upward or downward accordingly.

[0040] Specifically, when a depression appears on the road surface, the moving wheel 417 drives the vertical rod 415, the control plate 416 and the fixed frame 418 to move downward. At this time, the control plate 416 cooperates with the guide wheel 414 to push the sealing plate 411 to move to the side away from the fixed frame 418, so that the portion of the discharge trough 412 in the collecting hopper 46 increases. In this way, the discharge amount of concrete will increase accordingly, thereby effectively filling the depressions on the road surface. On the contrary, when a bulge appears on the road surface, the moving wheel 417 drives the vertical rod 415, the control plate 416 and the fixed frame 418 to move upward. In this case, the control plate 416 cooperates with the guide wheel 414 to push the sealing plate 411 to move to one side of the fixed frame 418, resulting in a decrease in the portion of the discharge trough 412 in the collecting hopper 46, thereby reducing the discharge amount of concrete. This design avoids excessive accumulation of concrete at the bulges of the road surface.

[0041] In this way, the leveling device can automatically adjust the discharge volume according to the actual situation of the road surface to ensure the flatness of the concrete paving. By automatically adjusting the size of the discharge trough 412, the device can accurately control the discharge volume of concrete according to the actual road surface conditions. In the depressions of the road surface, the concrete discharge volume is increased to fill the depressions; in the convex parts of the road surface, the concrete discharge volume is reduced to avoid excessive accumulation. This intelligent adjustment ensures the flatness of the concrete paving and improves the quality of road construction, allowing the device to cope with various complex road conditions. Whether it is depression or convexity, it can be adapted by automatically adjusting the size of the discharge trough 412. This strong adaptability enables the system to be widely used in different types of road construction, thereby significantly improving the efficiency and quality of road construction.

[0042] Embodiment 2: Combination Figure 3 , Figure 8 As shown, on the basis of the first embodiment, a rotating rod 420 is specially designed and installed on one side of the control board 416. The rotating rod 420 is cleverly installed at the corresponding position of the box body 2. Two eccentric wheels 427 are fixedly connected at both ends of the rotating rod 420. The two eccentric wheels 427 are closely connected to the drive shaft 43 through a synchronous belt transmission member 421, ensuring efficient and stable transmission. In order to further enhance the stability of the system, a support plate 428 fixedly installed on the inner wall of the box body 2 is specially provided on one side of the eccentric wheel 427. A sliding rod 429 is slidably connected to the support plate 428. The bottom of the sliding rod 429 is fixedly connected to a connecting frame 430. The connecting frame 430 is designed to be slidably installed on the box body 2, and a lower pressing plate 433 is also fixedly connected to its bottom to ensure the compaction and leveling effect.

[0043] The inner side of the eccentric wheel 427 is specially provided with a sliding groove for the sliding setting of the mounting wheel 431. The mounting wheel 431 is mounted on the connecting frame 430 to ensure its close cooperation with the connecting frame 430. In order to further optimize the smoothness of the movement, a third damping spring 432 sleeved on the sliding rod 429 is also provided between the connecting frame 430 and the supporting plate 428. When the driving shaft 43 rotates, the rotating rod 420 is driven to rotate synchronously through the synchronous belt transmission member 421, thereby driving the eccentric wheel 427 to rotate. During the rotation process, the eccentric wheel 427 can effectively drive the mounting wheel 431, the connecting frame 430, and the sliding rod 429 to move up and down reciprocatingly under the elastic force of the third damping spring 432, thereby driving the lower pressing plate 433 to move up and down reciprocatingly. This reciprocating motion enables the lower pressing plate 433 to effectively compact and level the road surface on which the concrete is paved, thereby ensuring the flatness and quality of the road surface.

[0044] In addition, a row of cams 422 are fixedly installed on the outer wall of the rotating rod 420, and an L-shaped frame 423 is set on one side of the cam 422. A knocking rod 425 is fixedly connected to the side of the L-shaped frame 423 close to the collecting hopper 46. A fixed plate 424 is slidably connected to the knocking rod 425, and the fixed plate 424 is fixedly installed on the box body 2. In order to ensure that the movement of the knocking rod 425 is smoother and more stable, a second damping spring 426 sleeved on the knocking rod 425 is also set between the L-shaped frame 423 and the fixed plate 424. When the rotating rod 420 rotates, it will drive the cam 422 to rotate synchronously, and the cam 422 will push the The L-shaped frame 423 and the knocking rod 425 are moved toward one side of the aggregate hopper 46, and the second damping spring 426 is compressed. This compression effect enables the knocking rod 425 to effectively knock the outer wall of the aggregate hopper 46, so that the concrete in the aggregate hopper 46 can be discharged smoothly and avoid sticking to the inner wall of the aggregate hopper 46. As the cam 422 continues to rotate, the elastic force of the second damping spring 426 pushes the L-shaped frame 423 and the knocking rod 425 to move away from the aggregate hopper 46. This reciprocating motion ensures that the knocking rod 425 can continuously knock the aggregate hopper 46 to discharge the material, thereby improving the discharge efficiency and quality of the concrete.

[0045] In the embodiment of the present invention, the rotating rod 420 will drive the cam 422 to rotate synchronously during the rotation process. As the cam 422 rotates, it will apply force to push the L-shaped frame 423 and the knocking rod 425 to move toward one side of the aggregate hopper 46. This movement process will cause the second damping spring 426 to be compressed. When the second damping spring 426 is compressed, the knocking rod 425 will forcefully knock the outer wall of the aggregate hopper 46. This knocking action helps to ensure that the concrete in the aggregate hopper 46 can be discharged smoothly, thereby preventing the concrete from adhering to the inner wall of the aggregate hopper 46. As the cam 422 continues to rotate, under the elastic restoring force of the second damping spring 426, the L-shaped frame 423 and the knocking rod 425 will be pushed to move to the side away from the aggregate hopper 46. This reciprocating motion enables the knocking rod 425 to continuously knock the aggregate hopper 46 for material discharge, thereby maintaining smooth discharge of concrete.

[0046] At the same time, when the driving shaft 43 rotates, it will drive the rotating rod 420 to rotate synchronously through the synchronous belt transmission part 421. During the rotation process, the rotating rod 420 will further drive the eccentric wheel 427 to rotate. When the eccentric wheel 427 rotates, it will combine with the elastic force of the third damping spring 432, thereby driving the mounting wheel 431, the connecting frame 430 and the sliding rod 429 to move up and down reciprocatingly. This reciprocating up and down movement will further drive the lower pressure plate 433 to move up and down reciprocatingly. When the lower pressure plate 433 contacts the concrete pavement during the movement, it will compact and level the pavement. In this way, the lower pressure plate 433 can effectively compact and level the concrete pavement to ensure the flatness and quality of the pavement.

[0047] The present invention also discloses a leveling method for permeable concrete pavement, which specifically comprises the following steps:

[0048] Step 1: Load concrete into the box 2. The concrete in the box 2 is transported to the guide rack 41 through the pipeline. The servo motor 42 is turned on to drive the drive shaft 43 and the guide blade 44 to rotate synchronously, so that the guide blade 44 pushes the concrete to move during the rotation, drives the concrete to move to each discharge channel 45, and enters the collecting hopper 46;

[0049] Step 2: The concrete in the collecting hopper 46 is discharged through the discharging chute 412 and transported to the discharging hopper 48 through the conveying pipe 47, and then the discharging hopper 48 is used to lay the concrete on the road surface;

[0050] Step 3, the moving wheel 417 moves on the road surface as the vehicle body 1 moves, that is, when on a stable road section, the guide wheel 414 is located in the middle of the inclined end of the control plate 416, that is, half of the discharge trough 412 is located in the collecting hopper 46. When the road surface is concave or convex, the moving wheel 417 drives the vertical rod 415, the control plate 416 and the fixed frame 418 to move upward or downward. When the road surface is concave, the moving wheel 417 drives the vertical rod 415, the control plate 416 and the fixed frame 418 to move downward, so that the control plate 416 cooperates with the guide wheel 414 to push the sealing plate 411 to move away from the fixed frame 418, that is, the discharge trough 412 is half located in the collecting hopper 46. The trough 412 is located in the aggregate hopper 46 and is enlarged, so that the concrete discharge volume is increased, which is used to fill the depressions in the road surface. When a bulge appears on the road surface, the moving wheel 417 drives the vertical rod 415, the control board 416, and the fixed frame 418 to move upward, so that the control board 416 cooperates with the guide wheel 414 to push the sealing plate 411 to move toward the side of the fixed frame 418, that is, the discharge trough 412 is located in the aggregate hopper 46 and is reduced, so that the concrete discharge volume is reduced, thereby avoiding excessive accumulation of concrete at the bulges of the road surface. In this way, the leveling device can automatically adjust the discharge volume according to the actual situation of the road surface to ensure the flatness of the concrete paving.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
