Description

Technical Field

[0001] The utility model relates to the field of asphalt mixing and paving equipment, and more specifically, to a cold mix permeable asphalt paving device. Background Art

[0002] Cold mix colored permeable asphalt permeable pavement is a two-component synthetic resin adhesive, which can be combined with various aggregates to form a ground. It is made by mixing and modifying a variety of petrochemical products and polymer material modifiers. After curing, it has excellent adhesion and good toughness, and can resist the fine cracks that appear in the base material. The ground has relatively excellent properties of impact resistance, water resistance, and resistance to various chemicals, and has the characteristics of stable performance, bright color, and good road performance. When paving, cold mix colored permeable asphalt requires a corresponding device for cold mixing and paving.

[0003] The utility model with the authorization announcement number CN218643119U discloses a cold mix permeable asphalt paving device, including a first assembly, a paver, a compactor, a limiter, a toolbox, and a leveling device. By starting the motor, this utility model drives the mounting plate and the slider to rise or fall synchronously under the drive of the lead screw, and then drives the screed to rise or fall, so as to adjust its height to adapt to the required thickness of asphalt paving in different situations and meet the needs of road thickness. By opening the hydraulic cylinder, it pushes the mounting part to swing up and down around the fixed shaft, driving the claw rake and the connecting rake to adjust the angle synchronously to adapt to the actual leveling angle needs, improving the leveling efficiency, improving the thickness uniformity of the asphalt road paving, and further improving the consistency of the road compaction degree.

[0004] When the above scheme is used, the mixed permeable asphalt material is loaded into the paver. Subsequently, the permeable asphalt enters the paver and is cold mixed by the built-in stirrer, and then is discharged and paved through the bottom of the paver; although the cold mix asphalt in the paver will not coagulate due to stirring, when the asphalt is discharged from the paver, since the asphalt in the discharge port of the paver is left for a long time and coagulates, the asphalt in the paver cannot be discharged, and manual assistance is required for dredging. The operation is cumbersome, delaying the paving time and resulting in low paving efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the defects of the above-mentioned prior art, and provide a cold mix permeable asphalt paving device, which is used to solve the technical problems that the asphalt in the discharge port of the paver coagulates after being left for a long time, resulting in the inability to discharge the asphalt in the paver, requiring manual assistance for dredging, with cumbersome operation, delaying the paving time, and resulting in low paving efficiency.

[0006] The technical solution adopted by the utility model is a cold-mix permeable asphalt paving device, comprising a movable seat, a stirring mechanism and a paving mechanism installed on the movable seat; the stirring mechanism comprises a containing barrel and an agitator, the containing barrel is installed on the movable seat, the agitator is rotatably installed in the containing barrel, a discharge port is provided at the bottom of the containing barrel, a stirring grid wheel is rotatably connected in the discharge port, and the stirring grid wheel is driven to rotate when the agitator rotates.

[0007] The agitator can stir the permeable asphalt in the container to prevent it from coagulating. When the agitator rotates to stir the permeable asphalt in the container, it drives the stirring grid wheel to rotate at the same time. The stirring grid wheel rotates to stir the permeable asphalt in the discharge port, thereby preventing the permeable asphalt in the discharge port from coagulating. When discharging again, there is no need for manual assistance to dredge the discharge port, which saves a lot of manual dredging time and can effectively improve the paving efficiency.

[0008] Furthermore, the stirrer includes a rotating shaft and a stirring rod, the rotating shaft is rotatably connected to the container, the stirring rods are arranged in a circular array on the outer peripheral surface of the rotating shaft, and multiple layers are arranged along the axial direction of the rotating shaft, and the stirring rods in the bottom layer drive the stirring grid wheel to rotate when rotating. The arranged multiple layers of stirring rods can fully stir the water-permeable asphalt in the container, and can effectively prevent the water-permeable asphalt in the container from condensing. The stirring grid wheel is driven to rotate by the stirring rods, and there is no need to set a power drive for the stirring grid wheel, nor is there a need to connect the rotating shaft and the stirring grid wheel through a transmission mechanism, which can effectively save costs.

[0009] Furthermore, the stirring rod is L-shaped, and has a long rod end and a short rod end. The long rod end of the stirring rod is fixedly connected to the rotating shaft, and the short rod end of the stirring rod at the bottom layer on the rotating shaft is used to drive the stirring grid wheel to rotate. The stirring rod with the L-shaped structure can fully stir the permeable asphalt in the container, and the short rod end thereof protruding from the long rod end is more convenient for driving the stirring grid wheel to rotate.

[0010] Furthermore, a truncated platform is provided in the middle of the bottom of the container, and an annular groove is formed between the truncated platform and the inner wall of the container, and the short rod end of the stirring rod at the bottom layer on the rotating shaft runs in the annular groove, and the discharge port is provided at the bottom of the annular groove. When there is less water-permeable asphalt in the container, it will enter the annular groove due to gravity and stirring of the stirring rod, and finally all will be discharged through the discharge port in the annular groove, so that the water-permeable asphalt in the container can be discharged more thoroughly.

[0011] Furthermore, the outer circumference of the truncated cone is an inclined surface that gradually moves away from the rotation axis from top to bottom. The outer circumference of the truncated cone is set as an inclined surface, which can play a good guiding role. When the permeable asphalt is discharged to the end, the less permeable asphalt in the container can enter the annular groove more smoothly so as to be discharged from the discharge port.

[0012] Further, the stirring grid wheel includes a wheel shaft and grid plates. The wheel shaft is rotatably connected inside the discharge port. There are at least three grid plates evenly arranged on the outer peripheral surface of the wheel shaft. The distance from the center of the wheel shaft to the inner bottom surface of the containing barrel is less than half of the distance from the center of the wheel shaft to the outer end of the grid plate. When there are two grid plates, the angle between the two grid plates is 180 degrees. In this case, the grid plates may be parallel to the inner bottom surface of the containing barrel and hidden inside the discharge port, resulting in the situation where the stirring rod cannot act on it and drive it to rotate. When there are three grid plates, the included angle between the grid plates is 120 degrees, and the distance from the center of the wheel shaft to the inner bottom surface of the containing barrel is less than half of the distance from the center of the wheel shaft to the outer end of the grid plate, ensuring that at least one outer end of the grid plate or the outer end parts of two grid plates are higher than the inner bottom surface of the containing barrel during rotation. Thus, the stirring rod can always act on the grid plates to drive the stirring grid wheel to rotate, and the situation of unable to interact with each other will not occur.

[0013] Further, the stirring mechanism further includes a first driving component installed on the containing barrel, and the first driving component is used to drive the stirrer to rotate. The first driving component mainly plays the role of providing power to drive the rotating shaft to rotate, and motors in the prior art can be selected.

[0014] Further, the paving mechanism includes a paving assembly and a compaction assembly. The paving assembly is arranged on the front side of the moving seat and below the discharge port, and the compaction assembly is arranged on the rear side of the moving seat. The permeable asphalt discharged from the discharge port will first be leveled on the ground by the paving assembly. As the moving seat moves forward, the compaction assembly at the rear will flatten the leveled permeable asphalt, thus completing the paving.

[0015] Further, the paving assembly includes a rotating shaft, paving plates and a second driving component. The rotating shaft is rotatably installed below the moving seat. The paving plates are fixed on the rotating shaft and below the outlet end of the discharge port. The second driving component is installed on the moving seat and is used to drive the paving plates to rotate. The second driving component mainly plays the role of driving the paving plates to rotate, and the material discharged from the discharge port is scattered by the rotation of the paving plates, so that the permeable asphalt discharged from the discharge port is evenly spread and leveled.

[0016] Further, the second driving component is an electric telescopic rod. The electric telescopic rod is movably installed below the moving seat, and the telescopic end of the electric telescopic rod is fixedly connected to the paving plates through a connecting spring. The connecting spring can play a good steering role, enabling the telescopic end of the electric telescopic rod to be flexibly connected to the paving plates, which is convenient for driving the paving plates to rotate.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows: The stirrer can stir the permeable asphalt in the holding barrel to prevent it from coagulating. When the stirrer rotates to stir the permeable asphalt in the holding barrel, it simultaneously drives the stirring grid wheel to rotate. The rotation of the stirring grid wheel stirs the permeable asphalt in the discharge port, thereby preventing the permeable asphalt in the discharge port from coagulating. When discharging again, there is no need for manual assistance to dredge the discharge port, saving a large amount of manual dredging time and effectively improving the paving efficiency.

[0024] The drawings of the present utility model are only for illustrative purposes and should not be construed as a limitation to the present utility model. For better illustrating the following embodiments, some components in the drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0025] As Figure 1 shown, this solution discloses a cold mix permeable asphalt paving device, including a moving seat 1, a stirring mechanism 2 and a paving mechanism 3 installed on the moving seat 1.

[0026] As Figure 3 and 4As shown in the figure, the stirring mechanism 2 includes a holding barrel 4 and a stirrer 5. The holding barrel 4 is installed on the moving seat 1, and the stirrer 5 is rotatably installed in the holding barrel 4. A discharge port 6 is provided at the bottom of the holding barrel 4. A stirring grid wheel 7 is rotatably connected in the discharge port 6. When the stirrer 5 rotates, it drives the stirring grid wheel 7 to rotate. The stirrer 5 can stir the permeable asphalt in the holding barrel 4 to prevent it from coagulating. When the stirrer 5 rotates to stir the permeable asphalt in the holding barrel 4, it simultaneously drives the stirring grid wheel 7 to rotate. The rotation of the stirring grid wheel 7 stirs the permeable asphalt in the discharge port 6, thereby preventing the permeable asphalt in the discharge port 6 from coagulating. When discharging again, there is no need for manual assistance to dredge the discharge port, saving a large amount of manual dredging time and effectively improving the paving efficiency. The moving seat 1 can be a moving trolley in the prior art.

[0027] The stirrer 5 includes a rotating shaft 8 and stirring rods 9. The rotating shaft 8 is rotatably connected in the holding barrel 4. The stirring rods 9 are circularly arranged on the outer peripheral surface of the rotating shaft 8 and are provided with multiple layers along the axial direction of the rotating shaft 8. When the lowermost layer of the stirring rods 9 rotates, it drives the stirring grid wheel 7 to rotate. The multiple layers of stirring rods 9 provided can fully stir the permeable asphalt in the holding barrel 4, effectively preventing the permeable asphalt in the holding barrel 4 from coagulating. By driving the stirring grid wheel 7 to rotate through the stirring rods 9, there is no need to additionally provide a power driving member for the stirring grid wheel 7, nor is it necessary to connect the rotating shaft 8 and the stirring grid wheel 7 through a transmission mechanism, effectively saving costs.

[0028] The stirring rod 9 has an L-shaped structure. The stirring rod 9 has a long rod end and a short rod end. The long rod end of the stirring rod 9 is fixedly connected to the rotating shaft 8. The short rod end of the lowermost layer of the stirring rods 9 on the rotating shaft 8 is used to drive the stirring grid wheel 7 to rotate. The L-shaped stirring rod 9 can fully stir the permeable asphalt in the holding barrel 4, and at the same time, its short rod end extends out of the long rod end, making it more convenient to drive the stirring grid wheel 7 to rotate.

[0029] A frustum 10 is provided in the middle of the inner bottom of the holding barrel 4. An annular groove 11 is formed between the frustum 10 and the inner wall of the holding barrel 4. The short rod end of the lowermost layer of the stirring rods 9 on the rotating shaft 8 runs in the annular groove 11. The discharge port 6 is provided at the bottom of the annular groove 11. When the amount of permeable asphalt in the holding barrel 4 is small, it will enter the annular groove 11 under the action of gravity and the stirring of the stirring rods 9, and finally all be discharged through the discharge port 6 in the annular groove 11, enabling the permeable asphalt in the holding barrel 4 to be discharged more thoroughly.

[0030] The outer peripheral surface of the frustum 10 is an inclined surface that gradually moves away from the rotating shaft 8 from top to bottom. The outer peripheral surface of the frustum 10 being set as an inclined surface can play a good guiding role. When the permeable asphalt is discharged to the end, it can make the less permeable asphalt in the holding barrel 4 enter the annular groove 11 more smoothly for discharge through the discharge port 6.

[0031] As Figure 4 and 5As shown, the stirring grid wheel 7 includes a wheel shaft 12 and a grid plate 13. The wheel shaft 12 is rotatably connected to the discharge port 6. No less than three grid plates 13 are evenly arranged on the outer peripheral surface of the wheel shaft 12. The distance from the center of the wheel shaft 12 to the inner bottom surface of the container 4 is less than half of the distance from the center of the wheel shaft 12 to the outer end of the grid plate 13. When there are two grid plates 13, the angle between the two grid plates 13 is 180 degrees. At this time, the grid plates 13 are parallel to the inner bottom surface of the container 4 and hidden in the discharge port 6, so that the stirring rod 9 cannot interact with it and cannot drive it to rotate. When there are three grid plates 13, as shown in FIG. Figure 5 As shown, the angle between the grid plates 13 is one hundred and twenty degrees, and when the distance from the center of the axle 12 to the inner bottom surface of the containing barrel 4 (i.e., a in the figure) is less than half the distance from the center of the axle 12 to the outer end of the grid plate 13 (i.e., half of b shown in the figure), during the rotation, at least one outer end of the grid plate 13 or the outer end parts of two grid plates 13 are higher than the inner bottom surface of the containing barrel 4, so that the stirring rod 9 can always act with the grid plate 13 to drive the stirring grid wheel 7 to rotate, and the situation of being unable to drive the rotation will not occur.

[0032] like Figure 3 As shown, the stirring mechanism 2 also includes a driving component 14 installed on the container 4, and the driving component 14 is used to drive the stirrer 5 to rotate. The driving component 14 mainly provides power to drive the rotating shaft 8 to rotate, and a motor in the prior art can be selected.

[0033] like Figure 1 and 2 As shown, the paving mechanism 3 includes a paving assembly 15 and a compacting assembly 16. The paving assembly 15 is arranged at the front side of the moving seat 1 and below the discharge port 6, and the compacting assembly 16 is arranged at the rear side of the moving seat 1. After the permeable asphalt discharged from the discharge port 6 falls, it will be paved on the ground by the paving assembly 15. As the moving seat 1 moves forward, the compacting assembly 16 at the rear side will flatten the paved permeable asphalt, thereby completing the paving.

[0034] like Figure 2 and 3 As shown, the paving assembly 15 includes a rotating shaft 17, a paving plate 18 and a second driving component 19. The rotating shaft 17 is rotatably mounted below the moving seat 1. The paving plate 18 is fixed on the rotating shaft 17 and is located below the outlet end of the discharge port 6. The second driving component 19 is mounted on the moving seat 1 to drive the paving plate 18 to rotate. The second driving component 19 mainly drives the paving plate 18 to rotate. The paving plate 18 rotates to spread the material discharged from the discharge port 6, so that the permeable asphalt discharged from the discharge port 6 is evenly spread and paved.

[0035] The driving component two 19 is an electric telescopic rod, which is movably installed below the moving seat 1. The telescopic end of the electric telescopic rod is fixedly connected to the paving plate 18 through a connecting spring 20. The connecting spring 20 can play a good steering role, enabling the telescopic end of the electric telescopic rod to be flexibly connected to the paving plate 18, facilitating the rotation of the paving plate 18.

[0036] Usage instructions: First, add permeable asphalt into the storage barrel 4, and drive the agitator 5 to rotate through the driving component one 14 to stir the permeable asphalt to prevent it from coagulating; when the agitator 5 rotates, the short rod end of the stirring rod 9 drives the stirring grid wheel 7 to rotate through the grid plate 13, and the stirring grid wheel 7 stirs the permeable asphalt in the discharge port 6 to prevent it from coagulating; during paving, open the discharge port 6, the agitator 5 rotates to drive the stirring grid wheel 7 to rotate, so that the permeable asphalt inside the storage barrel 4 is discharged and falls from the discharge port 6. At the same time, the driving component two 19 drives the paving plate 18 to rotate reciprocally through the connecting spring 20, thereby dispersing and paving the falling permeable asphalt on the road surface. As the moving seat 1 moves, the rear compaction component 16 compacts and levels the paved permeable asphalt; when there is less permeable asphalt in the storage barrel, due to the stirring of the agitator 5 and the gravity factor, all the permeable asphalt will be collected in the annular groove 11 and discharged completely through the discharge port 6.

[0037] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the technical solutions of the present invention, rather than limitations on the specific implementation manners of the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the claims of the present invention shall be included within the protection scope of the claims of the present invention.
