Description

Technical Field

[0001] The present invention belongs to the field of pavement paving devices, and in particular to a solid waste material paving device, a paving method and an application thereof in a permeable asphalt pavement. Background Art

[0002] With the rapid development of industrialization and urbanization across the country, the amount of solid waste generated has been increasing year by year, bringing tremendous pressure to the environment. At the same time, the demand for high-quality materials in transportation infrastructure construction is also growing. In this case, after the prepared asphalt mixture containing solid waste materials is transported to the construction site, it is then laid on the road base to form an asphalt pavement, realizing the effective utilization of solid waste materials.

[0003] The Chinese patent application number CN202210785172.9 discloses a road solid waste paving control device for asphalt pavement, including a screening mechanism for screening solid waste by size, the screening mechanism including symmetrically arranged mounting plates, a plurality of screening columns arranged between the symmetrically arranged mounting plates, and the gap between adjacent screening columns gradually increases from the feed end to the discharge end. The solid waste paving device cannot adapt to the paving of asphalt pavements of different widths and has poor applicability.

[0004] After the asphalt mixture containing solid waste materials is transported to the pavement base by the transportation mechanism, the spiral agitator disperses the asphalt mixture over the entire paving width, which can easily lead to a relatively dense asphalt mixture in the middle area of ​​the pavement width, while the asphalt mixture on both sides is relatively sparse. This uneven distribution will directly affect the flatness of the asphalt pavement.

[0005] In addition, when the asphalt mixture is released from the transport mechanism and falls to the pavement base, due to the large falling height, aggregates of different particle sizes are subject to different air resistance. Coarse aggregates are less affected by air resistance and will fall to the pavement base before fine aggregates. Fine aggregates are lighter and more affected by air resistance, so they will fall later, causing coarse aggregates to be mainly distributed in the lower layer, while fine aggregates are mainly distributed in the upper layer. This stratification phenomenon will weaken the structural uniformity of the asphalt mixture, thereby affecting the bearing capacity of the pavement.

[0006] When the surface of the road base is uneven, the demand for asphalt mixture in different areas will vary. However, the paving device in the existing technology lacks the ability to adaptively adjust the feeding rate of the asphalt mixture, resulting in the supply of the mixture during the paving process being unable to match the actual demand of the base surface, further reducing the flatness and bearing capacity of the asphalt pavement. Summary of the invention

[0007] In view of the above problems, the present invention provides a solid waste material paving device, a paving method and an application in a permeable asphalt pavement to solve the problems raised in the above background technology.

The extending end of the feeding mechanism is located in the material passage hole and close to the supporting assembly.

[0011] Preferably, hinged seats are provided on both sides of the frame assembly, the two hinged seats are fixedly connected to the input ends of the hydraulic push rods, the output ends of the hydraulic push rods are connected to fixed seats, and ironing plates are connected between the fixed seats.

[0012] Preferably, an electric push rod is provided at the bottom of the base plate, and the bottom of the electric push rod is fixedly connected to the L-shaped support plate. A connecting hole is opened on the side of the base plate close to the box body, and a rotating shaft is rotatably connected inside the connecting hole. Fixed plates are fixedly connected on both sides of the rotating shaft, and the bottom of the fixed plate is fixedly connected to the L-shaped support plate.

[0013] Preferably, vertical plates are fixedly connected to the tops of the bottom plates on both sides, and the space enclosed between the vertical plates and the bottom plates forms a material storage bin.

[0014] Preferably, a connecting rod is provided inside the spiral agitator, both ends of the connecting rod are connected to connecting plates, and the side of the connecting plate away from the connecting rod is fixedly connected to the side wall of the ironing plate.

[0015] The present invention also discloses a paving method of a solid waste material paving device, comprising the following steps: S1. According to the width of the asphalt pavement to be paved, the central control module controls the electric push rods of the support components on both sides of the paving device to start, driving the bottom plate to rotate around the rotation axis, causing the limit plate to approach or move away from the U-shaped rod, thereby controlling the discharge range of the solid waste asphalt mixture of the adjustment component; S2, control the hydraulic push rod to start, the output end of the hydraulic push rod extends, driving the ironing plate and the mixing assembly to approach the adjustment assembly, and at the same time control the hydraulic push rod to rotate around the hinge seat, so that the bottom height of the ironing plate is flush with the paving height of the asphalt road surface; S3, controlling the output ends of each group of electric push rods to shorten simultaneously, so that the bottom of the bottom plate is close to the road base, and the height of the bottom plate from the road base reaches a preset height value; S4, the solid waste asphalt mixture is released from the feeding mechanism into the storage bin and transferred and stored in the storage bin, and the solid waste asphalt mixture falls from the gap between the limit plate and the blocking plate onto the road base; S5. The mixing assembly is started, and the spiral agitator starts to operate, driving two sets of spiral mixing blades in opposite directions to rotate synchronously, thereby driving the solid waste asphalt mixture to move from the middle area of ​​the mixing assembly to both sides. As the paving device moves, the screed plate spreads the solid waste asphalt mixture; S6. According to the rotation of the bottom plate, the concave and convex conditions on the road surface base are determined at a fixed point, and the bottom of the bottom plate is set to contact the road surface base. When the paving device moves to the concave area of ​​the road surface base, the bottom plate moves along the surface path of the concave area, driving the gap between the limit plate and the blocking plate to increase, and at the same time increasing the stirring rate of the spiral stirrer; When the paving device moves to the raised area of ​​the road base, the bottom plate moves along the surface path of the raised area, which reduces the gap between the limit plate and the blocking plate and reduces the stirring rate of the spiral agitator.

[0016] An application of the solid waste material paving device in a permeable asphalt pavement.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present application sets up the mutual cooperation of the supporting components, adjusting components and stirring components. When the paving device moves to the concave area or the convex area of ​​the road base, the bottom plate is always in contact with different areas of the road base, which solves the problem that the solid waste asphalt mixture is easy to be stratified and segregated when it falls. The size of the gap between the limit plate and the blocking plate is adjusted accordingly, so that the paving device has the ability of adaptive feeding. At the same time, the change of the stirring component speed is controlled to ensure that the solid waste asphalt mixture in different areas of the road base is evenly dispersed. In addition, the blocking plate continuously shears the solid waste asphalt mixture, which further improves the paving uniformity of the solid waste mixture.

[0018] 2. The present application sets up the mutual cooperation of components such as the electric push rod, the base plate and the adjustment assembly. When the electric push rod is started, it drives the base plate to rotate around the rotation axis. The rotation of the base plate drives the limit plate to move closer to or away from the U-shaped rod, causing the gap between the limit plate and the blocking plate to open or close, thereby controlling the discharge range of the solid waste asphalt mixture on the adjustment assembly, ensuring that the paving device can adapt to the paving needs of asphalt pavements of different widths.

[0019] 3. The present application sets up the coordination of components such as the adjusting assembly and the stirring assembly. When the solid waste asphalt mixture falls onto the pavement base, the stirring assembly at the corresponding position is started, so that the solid waste asphalt mixture can be evenly dispersed within the stirring range covered by each group of stirring assemblies, thereby ensuring the uniform distribution of the solid waste asphalt mixture within the paving width of the entire pavement base, and effectively ensuring the flatness and bearing capacity of the asphalt pavement.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0023] Embodiment 1: like Figure 1-2 As shown, a solid waste material paving device includes a frame assembly 1, to which a support assembly 2 is connected. The support assembly 2 is used for transferring and storing asphalt mixture containing solid waste materials (hereinafter referred to as solid waste asphalt mixture). The support assembly 2 is connected with an adjusting assembly 3. The frame assembly 1 transports the solid waste asphalt mixture to the support assembly 2, and the solid waste asphalt mixture in the support assembly 2 falls onto the pavement base through the adjusting assembly 3. A stirring assembly 4 is provided on the side of the adjusting assembly 3 away from the support assembly 2. The stirring assembly 4 is connected to the frame assembly 1, and the stirring assembly 4 uniformly stirs the solid waste asphalt mixture on the pavement base to uniformly disperse the asphalt mixture.

[0024] When the solid waste asphalt mixture falls from the paving device to the road base, the coarse aggregate and the fine aggregate are easily separated due to the high falling height. The falling height of the solid waste asphalt mixture can be reduced by setting the support assembly 2, such as Figure 2As shown, the frame assembly 1 includes a central control module 102, which is connected to the box 101. The central control module 102 can detect and control various electrical components inside the frame assembly 1. The frame assembly 1 includes a box 101. The box 101 is provided with a material through hole 103. The setting of the material through hole 103 facilitates the transportation of the solid waste asphalt mixture to the support assembly 2. A feeding mechanism 106 is provided on the end of the frame assembly 1 away from the support assembly 2. The feeding mechanism 106 rotates and drives the transportation of the solid waste asphalt mixture. Both sides of the feeding mechanism 106 are connected with gathering plates 107. The setting of the gathering plates 107 prevents the solid waste asphalt mixture from overflowing from both sides. The extended end of the feeding mechanism 106 is located in the material through hole 103 and close to the support assembly 2. Figure 3-6 As shown, the support assembly 2 includes a plurality of bottom plates 201, adjacent bottom plates 201 are in contact with each other, the bottom plates 201 are tilted, and their bottoms are close to the road base. The solid waste asphalt mixture flows through the bottom plates 201 and is discharged onto the road base, effectively reducing the falling height of the solid waste asphalt mixture. The tops of the bottom plates 201 on both sides of the paving device are fixedly connected with vertical plates 206. The space enclosed between the vertical plates 206 and the bottom plates 201 forms a storage bin 207. The solid waste asphalt mixture enters the storage bin 207 and is piled up to complete the transfer storage. Figure 7-8 As shown, the adjustment component 3 includes a U-shaped rod 303, and a plurality of blocking plates 302 are evenly arranged on the U-shaped rod 303. The setting of the U-shaped rod 303 ensures that the heights of the plurality of blocking plates 302 are always consistent. The two sides of the blocking plates 302 are sealed and slidably connected with the limiting plates 301. The two limiting plates 301 between adjacent blocking plates 302 are in conflict with each other. The end of the limiting plate 301 away from the U-shaped rod 303 is fixedly connected to the bottom plate 201. When the bottom plate 201 rotates, it can drive the limiting plates 301 to rotate synchronously. When in use, the solid waste asphalt mixture in the storage bin 207 can fall onto the road base through the gap between the limiting plate 301 and the blocking plate 302. The falling height of the solid waste asphalt mixture is small, which can effectively solve the problem of easy stratification and segregation of coarse aggregate and fine aggregate in the solid waste asphalt mixture.

[0025] It should be noted that after the solid waste asphalt mixture enters the storage bin 207, the material level of the solid waste asphalt mixture is maintained below the height of the vertical plate 206 and the limit plate 301, that is, the supply rate of the solid waste asphalt mixture will not exceed the transfer storage limit of the storage bin 207, ensuring the high efficiency and stability of the solid waste asphalt mixture processing.

[0026] In actual use, the paving device cannot adapt to different widths of road surfaces. When encountering road surfaces with varying widths, the paving device needs to be replaced frequently, which greatly reduces the construction efficiency. Figure 3-8As shown, an L-shaped support plate 104 is fixedly connected to the bottom of the box 101, and the L-shaped support plate 104 mainly provides stable physical support for the support component 2 and the adjustment component 3. A column 105 is fixedly connected to the L-shaped support plate 104, and the side of the column 105 away from the box 101 is fixedly connected to the U-shaped rod 303. The fixed connection between the U-shaped rod 303 and the column 105 improves the stability of the adjustment component 3. An electric push rod 202 is provided at the bottom of the bottom plate 201, and the bottom of the electric push rod 202 is fixedly connected to the L-shaped support plate 104 A connecting hole 203 is provided on one side of the bottom plate 201 close to the box body 101, and a rotating shaft 204 is rotatably connected inside the connecting hole 203. Fixed plates 205 are fixedly connected on both sides of the rotating shaft 204. The electric push rod 202 is started and the output end drives the bottom plate 201 to rotate around the rotating shaft 204 and realizes the adjustment and control of the height of the bottom plate 201. The bottom of the fixed plate 205 is fixedly connected to the L-shaped support plate 104, and the fixed plate 205 is fixedly connected to the L-shaped support plate 104, which further improves the structural stability of the support assembly 2. When the width of the paved road surface changes, the central control module 102 controls the electric push rods 202 on both sides of the paving device support component 2 to start, driving the bottom plates 201 on both sides to rotate around the rotating shaft 204. The rotation of the bottom plate 201 drives the limit plate 301 to approach or move away from the U-shaped rod 303, causing the gap between the limit plate 301 and the blocking plate 302 to open or close, thereby controlling the discharge range of the solid waste asphalt mixture on the adjustment component 3, ensuring that the paving device can adapt to the paving needs of asphalt roads of different widths.

[0027] It should be noted that, since the adjacent bottom plates 201 are in close contact with each other and the bottom plate 201 itself has a certain thickness, during the rotation of the bottom plate 201 around the rotation axis 204, its upper end surface will never be lower than the lower end surface of the adjacent bottom plate 201, and its lower end surface will never be higher than the upper end surface of the adjacent bottom plate 201. Therefore, the solid waste asphalt mixture will not leak out from the gap between the adjacent bottom plates 201.

[0028] After the solid waste asphalt mixture falls onto the road base, the existing technology cannot evenly disperse the solid waste asphalt mixture over the entire paving width, thereby affecting the flatness of the asphalt road surface. By setting multiple groups of stirring components 4 to interfere with each other, the uniformity of the solid waste asphalt mixture is increased, thereby Figure 2 , Fig. 9As shown, hinge seats 108 are provided on both sides of the frame assembly 1, and the two hinge seats 108 are fixedly connected to the input end of the hydraulic push rod 109, and the output end of the hydraulic push rod 109 is connected to a fixed seat 110, and an ironing plate 111 for leveling and compacting the solid waste asphalt mixture on the road base is connected between the fixed seats 110. The central control module 102 controls the hydraulic push rod 109 to start and extend the output end, driving the ironing plate 111 and the stirring assembly 4 to approach the adjustment assembly 3, and then controls the hydraulic push rod 109 to rotate around the hinge seat 108, so as to achieve that the bottom height of the ironing plate 111 is flush with the paving height of the asphalt road surface, ensuring the smoothness and accuracy of the paving process; a plurality of stirring assemblies 4 are provided on the side of the adjustment assembly 3 away from the support assembly 2, and the adjacent stirring assemblies 4 conflict with each other, and the plurality of stirring assemblies 4 are connected to the frame assembly 1. The stirring assembly 4 includes a spiral stirrer 403, a connecting rod 402 is arranged inside the spiral stirrer 403, and connecting plates 401 are connected to both ends of the connecting rod 402. The side of the connecting plate 401 away from the connecting rod 402 is fixedly connected to the side wall of the ironing plate 111. The positions of the multiple groups of stirring assemblies 4 and the ironing plate 111 are relatively fixed, which improves the stability of the stirring assembly 4 when working. In addition, the spiral stirrer 403 is equipped with two groups of spiral stirring blades in opposite directions. After the solid waste asphalt mixture falls onto the road base, the central control module 102 controls the stirring assembly 4 at the corresponding position of the solid waste asphalt mixture to work, so that the solid waste asphalt mixture can be evenly dispersed within the stirring range covered by each group of stirring assemblies 4, thereby ensuring that the solid waste asphalt mixture within the paving width of the entire road base is evenly distributed, and effectively ensuring the flatness of the asphalt road surface.

[0029] The working principle of the present invention is as follows: first, the staff controls the cooperation between the supporting assembly 2 and the adjusting assembly 3 according to the width of the asphalt pavement to be paved, thereby ensuring that the feeding range of the solid waste asphalt mixture is consistent with the width of the asphalt pavement. Specifically, when the width of the pavement to be paved is small, the central control module 102 controls the electric push rods 202 of the supporting assemblies 2 on both sides of the paving device to start, and the output ends of the electric push rods 202 extend, thereby driving the bottom plate 201 to rotate away from the L-shaped supporting plate 104, and the bottom plate 201 drives the limiting plate 301 to move upward and gradually approach the U-shaped rod 303, causing the top of the limiting plate 301 to conflict with the U-shaped rod 303, thereby achieving complete closure of the gap between the limiting plates 301 and the blocking plates 302 on both sides, and the solid waste asphalt mixture. The liquid is discharged from the gap between the limit plate 301 and the blocking plate 302 in the middle part of the adjustment component 3, ensuring that the paving device can adapt to the paving requirements of asphalt pavements of different widths, thereby improving the accuracy and work efficiency of paving; similarly, when the width of the road to be paved is large, the central control module 102 controls the electric push rods 202 of the support components 2 on both sides of the paving device to start, and the output ends of the electric push rods 202 are shortened, thereby driving the bottom plate 201 to rotate in the direction close to the L-shaped support plate 104, and the bottom plate 201 drives the limit plate 301 to move downward and gradually away from the U-shaped rod 303, thereby realizing the opening of the gap between the limit plate 301 and the blocking plate 302 on both sides, further ensuring that the paving device can adapt to the paving requirements of asphalt pavements of different widths, thereby improving the accuracy and work efficiency of paving.

[0030] Secondly, the central control module 102 controls the hydraulic push rod 109 to start, and the output end of the hydraulic push rod 109 extends, driving the ironing plate 111 and the mixing component 4 to approach the adjustment component 3, and at the same time controls the hydraulic push rod 109 to rotate around the hinge seat 108, so that the bottom height of the ironing plate 111 is flush with the paving height of the asphalt road surface, thereby facilitating the subsequent mixing and leveling of the solid waste asphalt mixture. The transport vehicle loaded with the solid waste asphalt mixture slowly unloads the solid waste asphalt mixture onto the feeding mechanism 106. Under the transportation action of the feeding mechanism 106, the solid waste asphalt mixture continues to pass through the material hole 103 and is transported to the support component 2.

[0031] Then, the central control module 102 controls the output end of each group of electric push rods 202 to shorten at the same time, so that the bottom of the bottom plate 201 is close to the road base, and the height of the bottom plate 201 from the road base reaches a preset height value, and at the same time, the transportation speed of the feeding mechanism 106 is set so that the feeding speed of the solid waste asphalt mixture meets the construction requirements. The preset height value ensures that the solid waste asphalt mixture falls at a low height. The solid waste asphalt mixture is released from the feeding mechanism 106 into the storage bin 207 and transferred and stored in the storage bin 207. Then, the solid waste asphalt mixture falls from the gap between the limit plate 301 and the blocking plate 302 to the road base, thereby solving the problem of easy stratification and segregation of coarse aggregate and fine aggregate in the solid waste asphalt mixture.

[0032] Finally, after the solid waste asphalt mixture falls onto the pavement base, the solid waste asphalt mixture will gradually accumulate in the middle area of ​​each group of mixing components 4. At this time, the central control module 102 controls the mixing component 4 at the corresponding position to start, and the spiral agitator 403 starts to operate, driving the two groups of spiral mixing blades in opposite directions to rotate synchronously, thereby driving the solid waste asphalt mixture to move from the middle area of ​​the mixing component 4 to both sides, so that the solid waste asphalt mixture can be evenly dispersed to the width covered by each group of mixing components 4, thereby ensuring the uniform distribution of the solid waste asphalt mixture within the paving width of the entire pavement base, which can effectively ensure the flatness and bearing capacity of the asphalt pavement. As the paving device moves, the ironing plate 111 spreads the solid waste asphalt mixture, thereby completing the paving of the solid waste asphalt mixture.

[0033] Embodiment 2: Based on the technical solution of the above-mentioned embodiment 1, since the asphalt pavement base usually adopts inorganic binder stabilized materials and graded crushed stone materials, the surface of such materials is often prone to a lot of uneven conditions after the paving operation is completed. Therefore, when the surface of the pavement base is uneven, the demand for solid waste asphalt mixture in different areas of the pavement base is also different. The demand for solid waste asphalt mixture in the raised area of ​​the pavement base is relatively small, and the demand for solid waste asphalt mixture in the recessed area of ​​the pavement base is relatively large. However, the existing technology lacks the ability to adaptively adjust the feeding rate of solid waste asphalt mixture, resulting in the inconsistency between the supply of asphalt mixture in different areas of the pavement base and the actual demand, which reduces the flatness and bearing capacity of the asphalt pavement. In order to solve the above-mentioned problem, embodiment 2 is proposed.

[0034] During actual use, the paving device can determine the unevenness of the road surface base according to the rotation of the bottom plate 201, and adjust the feeding rate of the asphalt mixture adaptively to ensure that the solid waste asphalt mixture in different areas of the road surface base is evenly laid, specifically: First, the central control module 102 controls the output ends of each group of electric push rods 202 to shorten at the same time, driving the bottom of the bottom plate 201 to contact the road base, and the bottom plate 201 drives the limit plate 301 to rotate close to the road base, causing the gap between the limit plate 301 and the blocking plate 302 to be greater than the preset height value. The discharge speed of the solid waste asphalt mixture is faster, and the transportation speed of the feeding mechanism 106 can be reduced to meet the construction requirements. At the same time, the stirring rate of the spiral agitator 403 is set to reach the preset rate value, so that the solid waste asphalt mixture can be evenly dispersed in the stirring range covered by each group of stirring components.

[0035] Then, after the bottom of the bottom plate 201 touches the road surface base, the output end of each group of electric push rods 202 is controlled to continue to shorten, and at this time, the bottom plate 201 has a tendency to rotate downward. As the paving device moves slowly, when the paving device moves to the concave area of ​​the road surface base, the bottom plate 201 on the concave area is under the dual effects of the gravity of the solid waste asphalt mixture on the top and the electric push rod 202. The bottom plate 201 gradually descends to the lowest point along the surface path of the concave area, driving the limit plate 301 to rotate away from the U-shaped rod 303. The gap between the limit plate 301 and the blocking plate 302 gradually increases, and the volume of the solid waste asphalt mixture flowing through the gap per unit time gradually increases, effectively filling the concave area of ​​the road surface base, and at the same time gradually increasing the stirring rate of the spiral agitator 403, so that the spiral stirring blades can evenly mix the increased solid waste asphalt mixture. Disperse to avoid the situation that there is more solid waste asphalt mixture in the middle area of ​​the stirring component 4 and less solid waste asphalt mixture in the two side areas; when the bottom plate 201 rises from the lowest point to the height of the flat area of ​​the road base along the surface path of the concave area, it drives the limit plate 301 to rotate in the direction close to the U-shaped rod 303 until the bottom plate 201 contacts the flat area of ​​the road base again, and the gap between the limit plate 301 and the blocking plate 302 gradually decreases, and at the same time, the stirring rate of the spiral stirrer 403 is gradually reduced to reach the preset rate value, to prevent the stirring component 4 from over-stirring, to avoid the situation that there is less solid waste asphalt mixture in the middle area of ​​the stirring component 4 and more solid waste asphalt mixture in the two side areas. At the same time, when the paving device passes through the concave area of ​​the road base, the solid waste asphalt mixture falls from the support component 2 to the concave area. The drop height increases, which will cause the solid waste asphalt mixture to be stratified and segregated, but because the bottom plate 201 always contacts the surface path of the concave area, the drop height of the solid waste asphalt mixture is reduced, solving the problem of stratification and segregation of the solid waste asphalt mixture in the concave area.

[0036] Finally, similarly, when the paving device moves to the raised area of ​​the road base, the bottom plate 201 on the raised area is subject to the dual effects of the gravity of the solid waste asphalt mixture on the top and the electric push rod 202, and this dual effect cannot flatten the raised area. Therefore, the bottom plate 201 gradually rises to the highest point along the surface path of the raised area, driving the limit plate 301 to rotate in the direction close to the U-shaped rod 303, and the gap between the limit plate 301 and the blocking plate 302 gradually decreases, and the volume of the solid waste asphalt mixture flowing through the gap per unit time gradually decreases, thereby reducing the discharge of the solid waste asphalt mixture in the raised area of ​​the road base, ensuring the uniformity of the paving of the solid waste asphalt mixture, and at the same time, due to the gradual reduction of the solid waste asphalt mixture in the raised area , controlling the stirring rate of the spiral stirrer 403 to gradually decrease, preventing the stirring component 4 from over-stirring, resulting in less solid waste asphalt mixture in the middle area of ​​the stirring component 4 and more solid waste asphalt mixture in the two side areas; when the bottom plate 201 descends from the highest point along the surface path of the raised area to the height of the flat area of ​​the road base, it drives the limit plate 301 to rotate in the direction away from the U-shaped rod 303 until the bottom plate 201 hits the flat area of ​​the road base again, and the gap between the limit plate 301 and the blocking plate 302 gradually increases, and at the same time, the stirring rate of the spiral stirrer 403 is gradually increased to reach the preset rate value, avoiding the situation where there is more solid waste asphalt mixture in the middle area of ​​the stirring component 4 and less solid waste asphalt mixture in the two side areas.

[0037] In addition, the paving temperature of the solid waste asphalt mixture is generally not less than 135°C. At this time, the solid waste asphalt mixture has good fluidity. However, due to the low ambient temperature, the working temperature of the solid waste asphalt mixture will quickly dissipate into the paving device and the air, resulting in poor fluidity of the solid waste asphalt mixture. The spiral agitator 403 cannot evenly distribute the solid waste asphalt mixture to both sides, affecting the flatness of the road surface. However, during the slow movement of the paving device of this embodiment, the bottom plate 201 will always conflict with the surface path of the flat area, the concave area and the convex area. The bottom plate 201 drives the limiting plate 301 away from or close to the U-shaped rod 303, so that the gap between the limiting plate 301 and the blocking plate 302 continues to change, thereby realizing the blocking plate 302 to continuously shear the solid waste asphalt mixture, increasing the fluidity of the solid waste asphalt mixture, compensating for the problem of poor fluidity caused by the lower working temperature, so that the spiral agitator 403 can evenly distribute the solid waste asphalt mixture to both sides, further improving the paving uniformity of the solid waste mixture.

[0038] The solid waste material spreading device can determine the positions of depressions and protrusions on the road base in real time. When the spreading device moves to the depression area or the protrusion area of ​​the road base, it causes the bottom plate 201 to always contact different areas of the road base, solving the problem of easy stratification and segregation of the solid waste asphalt mixture when it falls. The size of the gap between the limit plate 301 and the blocking plate 302 is adjusted accordingly, so that the spreading device has the ability to self-adaptively discharge materials. At the same time, the speed change of the stirring component 4 is controlled to ensure that the solid waste asphalt mixture in different areas of the road base is evenly dispersed. In addition, the blocking plate 302 continuously shears the solid waste asphalt mixture, further improving the paving uniformity of the solid waste mixture.

[0039] The solid waste material paving device can be used in permeable asphalt pavement to improve the smoothness and bearing capacity of the permeable asphalt pavement.

[0040] Embodiment three: This embodiment discloses a paving method of a solid waste material paving device, comprising the following steps: S1. According to the width of the asphalt pavement to be paved, the central control module 102 controls the electric push rods 202 of the support components 2 on both sides of the paving device to start, driving the bottom plate 201 to rotate around the rotation axis 204, causing the limit plate 301 to approach or move away from the U-shaped rod 303, thereby controlling the discharge range of the solid waste asphalt mixture of the adjustment component 3; S2, control the hydraulic push rod 109 to start, the output end of the hydraulic push rod 109 extends, driving the ironing plate 111 and the stirring assembly 4 to approach the adjustment assembly 3, and at the same time control the hydraulic push rod 109 to rotate around the hinge seat 108, so that the bottom height of the ironing plate 111 is flush with the paving height of the asphalt road surface; S3, controlling the output ends of each group of electric push rods 202 to shorten simultaneously, so that the bottom of the bottom plate 201 is close to the road base, and the height of the bottom plate 201 from the road base reaches a preset height value; S4, the solid waste asphalt mixture is released from the feeding mechanism 106 into the storage bin 207, and is transferred and stored in the storage bin 207, and the solid waste asphalt mixture falls from the gap between the limiting plate 301 and the blocking plate 302 onto the road base; S5, the stirring assembly 4 is started, the spiral stirrer 403 starts to operate, driving two sets of spiral stirring blades in opposite directions to rotate synchronously, thereby driving the solid waste asphalt mixture to move from the middle area of ​​the stirring assembly 4 to both sides, and as the paving device moves, the screed plate 111 paves the solid waste asphalt mixture; S6. According to the rotation of the bottom plate 201, the concave and convex conditions on the road surface base are determined at a fixed point, and the bottom of the bottom plate 201 is set to contact the road surface base. When the paving device moves to the concave area of ​​the road surface base, the bottom plate 201 moves along the surface path of the concave area, driving the gap between the limit plate 301 and the blocking plate 302 to increase, and at the same time increasing the stirring rate of the spiral stirrer 403; When the paving device moves to the raised area of ​​the road base, the bottom plate 201 moves along the surface path of the raised area, driving the gap between the limit plate 301 and the blocking plate 302 to decrease, while reducing the stirring rate of the spiral stirrer 403.
