Description

Technical Field

[0001] The present application relates to the technical field of asphalt pavement construction, and in particular to asphalt pavement construction equipment and methods. Background Art

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt with mineral materials. The asphalt pavement construction process mainly includes: cleaning the road surface, asphalt paving, compaction, and water spray curing.

[0003] Currently, asphalt pavement construction equipment primarily consists of a paver. A mounting plate is located at the rear of the paver, and multiple nozzles for spraying asphalt are positioned along the length of the plate. These nozzles are arranged parallel to the width of the pavement. Asphalt within the paver is sprayed onto the construction surface through the nozzles, forming an asphalt layer.

[0004] Regarding the above-mentioned asphalt pavement construction equipment, when there is a lawn or flowers and trees next to the construction road surface, the asphalt sprayed by the nozzle at the end of the mounting plate is likely to splash onto the grass and trees next to the construction road surface, causing damage to the surrounding environment. Summary of the Invention

[0005] In order to facilitate shielding of splashing asphalt and prevent the asphalt from splashing onto the grass and trees next to the construction road surface, the present application provides asphalt pavement construction equipment and methods.

[0006] In the first aspect, the asphalt pavement construction equipment provided by this application adopts the following technical solutions:

[0007] Asphalt pavement construction equipment includes a paver body and a mounting plate arranged on the paver body, the mounting plate is used to install a nozzle for spraying asphalt, and baffles for shielding asphalt splashing are provided at both ends of the mounting plate in the length direction, a cavity is provided on the side of the baffle close to the road surface, an air bag for abutting the road surface is provided on the side of the baffle close to the road surface, the air bag is connected to the cavity, a piston block is slidably arranged in the cavity, the piston block slides toward or away from the air bag, an adjustment component is provided in the baffle, and the adjustment component is used to adjust the piston block to slide toward or away from the air bag.

[0008] By adopting the above technical solution, since there is a certain amount of air between the piston block and the air bag, when the adjustment component adjusts the piston block to slide toward the air bag, the air is pushed into the air bag, so that the air bag expands and contacts the road surface, blocking the gap between the baffle and the road surface. When asphalt is sprayed from the nozzle, the baffle and the inflated air bag block the splashing asphalt, so that the asphalt sprayed from the nozzles at both ends is not easy to splash onto the lawn or grass next to the road surface, thereby reducing damage to the surrounding environment to a certain extent.

[0009] Preferably, the adjustment assembly includes a spring arranged in the baffle and a pulling member arranged on the baffle, the spring is used to push the piston block to slide toward the direction close to the air bag, one end of the spring is arranged in the baffle, and the other end is arranged on the piston block, and the pulling member is used to pull the piston block to slide toward the direction away from the air bag.

[0010] By adopting the above technical solution, the spring pushes the piston block to slide toward the direction close to the air bag, pushing air into the air bag, causing the air bag to expand and abut against the road surface, thereby sealing the gap between the baffle and the road surface, effectively blocking the asphalt splashed out by the nozzle at the end, so that the asphalt is not easily splashed onto the grass and trees next to the construction road surface; the pulling member pulls the piston block to slide in the direction away from the air bag, at this time the air in the air bag is extracted, causing the air bag to be concave toward the direction close to the piston block, and the air bag is separated from the road surface, which is convenient for storage when not in use.

[0011] Preferably, the pulling member includes a pull rope that is slidably passed through the baffle, one end of the pull rope extends into the cavity and is connected to the piston block, and the other end extends outside the baffle. A hook is provided on the baffle, and a hanging ring is provided at one end of the pull rope located outside the baffle, and the hook is used to engage with the hanging ring.

[0012] By adopting the above technical solution, the drawstring is pulled, and the drawstring drives the piston block to slide in the direction away from the air bag, and the hanging ring on the drawstring is hung on the hook, thereby maintaining the position of the piston block. The piston block draws out the air in the air bag, causing the air bag to deflate in the direction close to the piston block, which helps to separate the air bag from the road and facilitates storage when not in use.

[0013] Preferably, the sliding direction of the piston block is set in the vertical direction, and a partition is rotatably provided on the side of the baffle close to the forward direction of the paver body. The partition is used to separate the construction area of ​​grass and trees from the road surface. The rotation axis of the partition is parallel to the sliding direction of the piston block. The piston block is provided with a first transmission part for driving the partition to rotate when the piston block slides. When the piston block slides toward the direction close to the air bag, the partition rotates toward the direction close to the paver body.

[0014] By adopting the above technical solution, when the piston block slides toward the direction close to the air bag, the first transmission member drives the partition to rotate a certain angle toward the direction close to the paver body. Since the partition is located on the side of the forward direction of the baffle, the paver body drives the partition forward, and the grass and trees beside the construction road surface are separated from the construction road surface. At the same time, the partition is tilted, and the side of the partition away from the baffle is located on the side of the grass and trees roots close to the paver body, which helps to push the grass and trees beside the construction road surface in the direction away from the paver body, so as to facilitate the transition of the roadside grass and trees to the side of the baffle away from the mounting plate, so as to reduce the possibility of the baffle directly penetrating into the grass and trees, and further make it difficult for the sprayed asphalt to splash onto the grass and trees beside the construction road surface, while effectively reducing the damage to the grass and trees when the baffle moves.

[0015] Preferably, a rotating shaft is provided on the partition, and the rotating shaft rotates on the baffle. The first transmission member includes a mounting rod provided on the piston block, a transmission rod hinged on the mounting rod, and a transmission plate sleeved on the rotating shaft. One end of the mounting rod extends outside the baffle, and a strip hole is provided on the baffle for the mounting rod to slide through. The piston block is located below the strip hole, and one end of the transmission rod is hinged to a side of the mounting rod outside the baffle, and the other end is hinged to an edge of the transmission plate away from the paver body.

[0016] By adopting the above technical solution, when the piston block slides toward the direction close to the air bag, the mounting rod drives one end of the transmission rod to move downward. At this time, the transmission rod pushes the transmission plate to rotate toward the direction close to the paver body, so that the rotating shaft drives the partition to rotate toward the direction close to the paver body, thereby helping to tilt the partition so that the partition can separate the grass and trees beside the construction road surface from the construction road surface, and in the process of the partition moving forward, it pushes the grass and trees beside the road surface to tilt in the direction away from the paver body, so that the grass and trees can transition through the partition to the side of the baffle away from the mounting plate, effectively shielding the grass and trees beside the construction road surface, so that asphalt is not easily splashed onto the grass and trees.

[0017] Preferably, the height of the partition decreases in a direction away from the rotation axis.

[0018] By adopting the above technical solution, the height of the partition decreases in the direction away from the rotation axis, which helps the partition to push the grass and trees from the root and separate them from the road surface, and at the same time helps to reduce the lateral damage of the partition to the grass and trees.

[0019] Preferably, a receiving plate is rotatably provided on one side of the partition close to the paver body, and the receiving plate rotates on the top wall of the partition. The receiving plate is used to receive fallen grass and leaves, and the receiving plate rotates toward or away from the partition. A second transmission member is provided on the baffle for driving the receiving plate to rotate when the partition rotates. When the partition rotates toward the direction close to the paver body, the receiving plate rotates toward the direction close to the partition.

[0020] By adopting the above technical solution, when the partition rotates toward the direction close to the paver body, the second transmission member drives the receiving plate to rotate toward the partition at a certain angle, so that the receiving plate and the top of the partition are at a certain angle, which helps to receive the grass and leaves that fall through the partition, so as to reduce the possibility of the grass and leaves scraped off by the partition falling onto the construction road surface, and is less likely to cause adverse effects on the construction.

[0021] Preferably, a rotating rod is provided on the supporting plate, and the rotating rod rotates on the partition. The second transmission member includes a torsion spring sleeved on the rotating rod, a first abutment block provided on the rotating rod, and a second abutment block provided on the baffle. The torsion spring is used to drive the supporting plate to rotate in a direction away from the partition. One end of the torsion spring is provided on the supporting plate, and the other end is provided on the partition. The second abutment block is located on the side of the partition close to the mounting plate. The second abutment block is used to push the first abutment block to drive the supporting plate to rotate in a direction close to the partition.

[0022] By adopting the above technical solution, when the partition rotates toward the direction close to the paver body, it drives the receiving plate and the rotating rod to rotate along the rotating shaft, so that the second abutment block and the first abutment block abut against each other, and the second abutment block pushes the first abutment block to drive the receiving plate to rotate a certain angle toward the direction close to the partition, which helps the receiving plate to receive the grass and leaves fallen from the partition and is not easy to affect the construction of the road surface; when the partition rotates toward the direction away from the paver body, the partition drives the first abutment block and the second abutment block on the rotating rod to disengage, and at this time the torsion spring drives the receiving plate to rotate toward the direction away from the partition to reset, so as to pour out the fallen grass and leaves from the side of the partition away from the paver body, which is simple and convenient.

[0023] Preferably, a wear-resistant protective cloth is detachably provided on the baffle, the wear-resistant protective cloth is located on a side of the air bag away from the piston block, and the wear-resistant protective cloth cover is provided outside the air bag.

[0024] By adopting the above technical solution, the wear-resistant protective cloth has a certain protective effect on the airbag, making the airbag less likely to be worn; the wear-resistant protective cloth and the baffle are detachable, which helps to clean or replace the wear-resistant protective cloth.

[0025] In the second aspect, the asphalt pavement construction method provided by this application adopts the following technical solutions:

[0026] The asphalt pavement construction method uses the asphalt pavement construction equipment and further includes the following steps:

[0027] Step 1: Clean the road surface: clean up the debris on the construction road surface and level the road surface;

[0028] Step 2: Asphalt paving: Move the paver to the desired location, and adjust the piston block through the adjustment assembly to slide toward the air bag, allowing air to enter the air bag, causing the air bag to expand and seal the gap between the baffle and the road surface. The asphalt in the paver is sprayed out through the nozzle on the mounting plate, and the baffle and air bag block the splashing asphalt.

[0029] Step 3: Compacting: Use a roller to compact the asphalt pavement;

[0030] Step 4: Water spraying: spray water on the asphalt layer for maintenance.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. Because there is a certain amount of air between the piston block and the air bag, when the piston block is adjusted to slide toward the air bag through the adjustment component, air is pushed into the air bag, causing the air bag to expand and contact the road surface, blocking the gap between the baffle and the road surface. When asphalt is sprayed from the nozzle, the baffle and the inflated air bag block the splashing asphalt, making it less likely for the asphalt sprayed from the nozzles at both ends to splash onto the grass or plants next to the road surface, thereby reducing damage to the surrounding environment to a certain extent;

[0033] 2. When the piston block slides toward the direction close to the air bag, the partition is driven by the first transmission member to rotate a certain angle toward the direction close to the paver body, so that the paver body drives the partition forward, and the grass and trees beside the construction road surface are separated from the construction road surface. At the same time, the partition is tilted, and the side of the partition away from the baffle is located on the side of the grass and trees roots close to the paver body, which helps to push the grass and trees beside the construction road surface in the direction away from the paver body, so as to facilitate the transition of the roadside grass and trees to the side of the baffle away from the mounting plate, so as to reduce the possibility of the baffle directly penetrating into the grass and trees.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1-6 This application is described in further detail.

[0042] The embodiment of the present application discloses an asphalt pavement construction equipment. Figure 1 and Figure 2 The asphalt pavement construction equipment includes a paver body 1 and a mounting plate 2 arranged on the paver, the length direction of the mounting plate 2 is perpendicular to the length direction of the paver body 1, and a plurality of nozzles for spraying asphalt are installed on the mounting plate 2 along the length direction. Baffles 3 for blocking asphalt splashing are fixedly connected at both ends of the mounting plate 2 along the length direction. The length direction of the mounting plate 2 is perpendicular to the plane where the baffles 3 are located. A cavity 4 is opened on the side of the baffle 3 close to the road surface, and an air bag 5 for abutting against the road surface is fixedly connected to the side of the baffle 3 close to the road surface. The air bag 5 is connected to the cavity 4, and the edge of the air bag 5 is fixedly bonded to the inner wall of the cavity 4. The air bag 5 closes the opening of the cavity 4, and a piston block 6 is slidingly arranged in the cavity 4. The sliding direction of the piston block 6 is arranged in the vertical direction, and the outer wall of the piston block 6 is tightly abutted against the inner wall of the cavity 4 to form a sealed space between the piston block 6 and the air bag 5. An adjusting component 7 for adjusting the piston block 6 to slide toward or away from the air bag 5 is provided in the baffle 3.

[0043] Reference Figure 2In order to facilitate the adjustment of the piston block 6 to slide in the direction close to or away from the air bag 5, the adjustment assembly 7 includes a spring 71 fixedly arranged on the bottom wall of the cavity 4 and a pulling member 72 arranged on the baffle 3. The spring 71 is used to push the piston block 6 to slide in the direction close to the air bag 5. One end of the spring 71 is fixedly connected to the bottom wall of the cavity 4, and the other end is fixedly connected to the side of the piston block 6 away from the air bag 5. The extension direction of the spring 71 is parallel to the sliding direction of the piston block 6. In this embodiment, three springs 71 are provided. The arrangement direction of the three springs 71 is perpendicular to the length direction of the mounting plate 2. The spring 71 adopts a high-strength spring, which helps to improve the pushing effect of the piston block 6; a telescopic rod 18 is fixed between the bottom wall of the cavity 4 and the piston block 6. The telescopic rod 18 and the spring 71 correspond one to one. The telescopic direction of the telescopic rod 18 is parallel to the extension direction of the spring 71. The spring 71 is movably sleeved on the corresponding telescopic rod 18. The provision of the telescopic rod 18 helps to guide the sliding of the piston block 6, and the pulling member 72 is used to pull the piston block 6 to slide in the direction away from the air bag 5.

[0044] Reference Figure 2 The pulling member 72 includes a pull rope 721 that is slidably inserted into the top wall of the baffle 3. One end of the pull rope 721 extends into the cavity 4 and is fixedly connected to the side of the piston block 6 away from the air bag 5, and the other end extends to the outside of the baffle 3. A hook 8 is fixedly provided on the side of the baffle 3 away from the mounting plate 2. The end of the pull rope 721 located outside the baffle 3 is fixedly connected to a hanging ring 9. The hanging ring 9 is used to engage with the hook 8. When the hanging ring 9 and the hook 8 are engaged, the air bag 5 is concave toward the direction close to the piston block 6.

[0045] During operation, the paver body 1 is moved to the required position of the construction road surface, so that the baffle 3 is located between the construction road surface and the grass and trees, and the hanging ring 9 is removed from the hook 8. At this time, the spring 71 pushes the piston block 6 to slide toward the direction close to the air bag 5. Since the piston block 6 and the air bag 5 are sealed and the amount of air is constant, the air is pushed into the air bag 5, causing the air bag 5 to swell and abut against the road surface, thereby blocking the gap between the bottom of the baffle 3 and the road surface. When the asphalt in the paver body 1 is sprayed out from the nozzle on the mounting plate 2, the baffle 3 and the air bag 5 block the splashing asphalt, so that the asphalt is not easily splashed onto the grass and trees next to the construction road surface; the form of the air bag 5 abutting against the road surface helps the air bag 5 adapt to the unevenness of the road surface.

[0046] When the asphalt is paved, the pull rope 721 is pulled to hook the hanging ring 9 on the pull rope 721 onto the hook 8. At this time, the pull rope 721 pulls the piston block 6 to slide away from the air bag 5. The air moves upward, causing the air bag 5 to concave toward the piston block 6, thereby separating the air bag 5 from the road surface, making it less likely for the air bag 5 to rupture quickly due to long-term wear, and facilitating the storage of the air bag 5.

[0047] Reference Figure 2A removable wear-resistant protective cloth 17 is provided on the side of the baffle 3 closest to the road surface. The wear-resistant protective cloth 17 is located on the side of the air bag 5 away from the piston block 6 and is covered by the wear-resistant protective cloth 17 outside the air bag 5. In this embodiment, the wear-resistant protective cloth 17 is made of nylon cloth and is fixed to the baffle 3 by screws. A Velcro strip (not shown) is provided between the wear-resistant protective cloth 17 and the air bag 5 to facilitate the fit of the wear-resistant protective cloth 17 and the air bag 5. In other embodiments, the wear-resistant protective cloth 17 can be fixed to the baffle 3 by bolts, thumbtacks, or the like. The provision of the wear-resistant protective cloth 17 protects the air bag 5, making it less susceptible to wear and adhesion to asphalt, thereby extending the service life of the air bag 5. At the same time, the removable connection between the wear-resistant protective cloth 17 and the baffle 3 facilitates cleaning or replacement of the wear-resistant protective cloth 17.

[0048] Reference Figure 2 and Figure 3 , the baffle 3 is close to the paver body 1 (refer to Figure 1 ) A partition 10 is provided on one side of the forward direction, and a rotating shaft 12 is coaxially passed through the partition 10. The rotating shaft 12 rotates on the baffle 3, and the rotating axis of the rotating shaft 12 is parallel to the sliding direction of the piston block 6. The partition 10 is used to separate the grass and trees and the construction area of ​​the road. The height of the partition 10 decreases in the direction away from the rotating shaft 12. The top wall of the partition 10 is set as an arc surface, and the arc surface bulges outward in the direction away from the road, which helps to reduce the lateral damage to the grass and trees on the roadside; a first transmission member 11 is provided on the piston block 6 for driving the partition 10 to rotate, and the first transmission member 11 includes a mounting rod 111 provided on the side of the piston block 6 away from the air bag 5, a transmission rod 112 hinged on the mounting rod 111 and a transmission disc 113 fixedly sleeved on the top of the rotating shaft 12, and the mounting rod 111 includes a first rod body 1111 fixed on the side of the piston block 6 away from the air bag 5 and a first rod body 1111 fixedly connected to the first rod body 1111 away from the air bag 5 The second rod body 1112 is away from one end of the piston block 6, the length direction of the first rod body 1111 is parallel to the sliding direction of the piston block 6, the length direction of the second rod body 1112 is perpendicular to the length direction of the first rod body 1111, the second rod body 1112 passes through the side of the baffle 3 away from the mounting plate 2 and extends to the outside of the cavity 4, and the side of the baffle 3 away from the mounting plate 2 is provided with a strip hole 13 for the second rod body 1112 to slide up and down through, and the strip hole 13 is located above the piston block 6 to ensure the sealing between the piston block 6 and the air bag 5; one end of the transmission rod 112 is hinged to the side of the second rod body 1112 outside the baffle 3, and the other end is hinged to the edge of the transmission plate 113 away from the side of the paver body 1, and the hinge axis of the transmission rod 112 is perpendicular to the rotation axis of the rotating shaft 12. When the piston block 6 slides toward the direction close to the air bag 5, the partition 10 rotates toward the direction close to the mounting plate 2.

[0049] Reference Figure 2A dividing rod 19 is fixed on the side of the partition 10 away from the baffle 3. The angle between the dividing rod 19 and the side of the partition 10 away from the mounting plate 2 is 155°-165°, which helps to make the plane of the dividing rod 19 and the baffle 3 parallel after the partition 10 is rotated a certain angle toward the direction close to the paver body 1.

[0050] When the piston block 6 slides in the direction close to the air bag 5, the first rod body 1111 drives the second rod body 1112 to move downward, so that the transmission rod 112 moves downward close to one end of the second rod body 1112, thereby causing the transmission rod 112 to push the transmission plate 113 to rotate in the direction close to the paver body 1, thereby causing the rotating shaft 12 to drive the partition 10 to rotate a certain angle in the direction close to the paver body 1, until the dividing rod 19 rotates to be parallel to the plane where the baffle 3 is located, and the paver body 1 is moved to the desired position, so that the dividing rod 19 is located on the side of the root of the grass close to the paver body 1. Since the baffle 10 is inclined, during the process of the paver body 1 moving forward, the dividing rod 19 first separates the roots of the grass from the road surface, and then pushes the grass in the direction away from the paver body 1 during the movement of the baffle 10, so that the grass can smoothly transition to the side of the baffle 3 away from the mounting plate 2, making it difficult for the baffle 3 to penetrate the grass and making part of the grass located in the construction road surface area, which is simple and convenient.

[0051] Reference Figure 5 and Figure 6 , the partition 10 is close to the paver body 1 (refer to Figure 1 ) is rotatably provided with a receiving plate 14 on one side, the receiving plate 14 rotates on the top wall of the partition 10, the receiving plate 14 is used to receive the grass and leaves that fall on the partition 10, the receiving plate 14 rotates in the direction close to or away from the partition 10, the rotation axis of the receiving plate 14 is parallel to the length direction of the edge of the top wall of the partition 10, the receiving plate 14 is coaxially fixed with a rotating rod 16, the rotating rod 16 rotates on the partition 10, the receiving plate 14 is fixedly connected to the side of the baffle 3 away from the side of the baffle 3 with a side plate 20, the side plate 20 is located above the partition rod 19, and the baffle 3 is provided with a second transmission member 15 for driving the receiving plate 14 to rotate when the partition 10 rotates, the second transmission member 15 includes a torsion spring 151 sleeved on the rotating rod 16, A first abutment block 152 is fixedly mounted on the rotating rod 16, and a second abutment block 153 is fixedly arranged on the side of the baffle 3 close to the partition 10. One end of the torsion spring 151 is fixed on the partition 10, and the other end is fixed on the receiving plate 14. The torsion spring 151 is used to drive the receiving plate 14 to rotate in the direction away from the partition 10. The longitudinal section of the first abutment block 152 is a triangle, and the side of the second abutment block 153 close to the partition 10 is an arc surface. The second abutment block 153 is used to abut against the bottom end of the first abutment block 152 to push the receiving plate 14 to rotate in the direction close to the partition 10. When the first abutment block 152 and the second abutment block 153 are disengaged, the torsion spring 151 drives the receiving plate 14 to be parallel to the partition 10.

[0052] When the partition 10 rotates toward the direction close to the paver body 1, the partition 10 drives the first abutment block 152 on the rotating rod 16 to rotate with the rotating shaft 12 as the axis, so that the first abutment block 152 and the second abutment block 153 on the baffle 3 abut, and the second abutment block 153 pushes the first abutment block 152 to drive the receiving plate 14 to rotate toward the direction close to the partition 10 by a certain angle, so that the end of the first abutment block 152 abuts against the partition 10. At this time, the rotation of the receiving plate 14 is limited, which is helpful to The partition 10 receives the fallen leaves and grass, and the setting of the side plate 20 reduces the falling of the fallen leaves and grass along the receiving plate 14, reducing the impact on the asphalt paving; when the partition 10 rotates in the direction away from the paver body 1, the first abutment block 152 and the second abutment block 153 gradually separate. At this time, the torsion spring 151 drives the receiving plate 14 to rotate in the direction away from the partition 10, so as to facilitate the pouring of the leaves and grass on the receiving plate 14 from the side of the partition 10 away from the paver body 1, which is simple and convenient.

[0053] Reference Figure 2 and Figure 4 , a connecting rod 21 is fixed to one end of the second rod body 1112 outside the baffle 3, and the connecting rod 21 is tilted. A slider 22 is fixed to the end of the connecting rod 21 away from the second rod body 1112. The slider 22 slides on the side of the baffle 3 away from the mounting plate 2. The sliding direction of the slider 22 is parallel to the sliding direction of the piston block 6. A sliding groove 23 is provided on the side of the baffle 3 away from the mounting plate 2 to slide with the slider 22. A connecting plate 24 is fixed to the slider 22. A shovel plate 25 is fixed to the side of the connecting plate 24 away from the slider 22. The shovel plate 25 is located on the baffle 3 close to the paver body 1 (refer to Figure 1 ) On the side of the forward direction, the shovel plate 25 is located below the partition 10, and the shovel plate 25 is used to abut against the road surface.

[0054] When the piston block 6 slides toward the direction approaching the air bag 5, the first rod body 1111 and the second rod body 1112 drive the connecting rod 21 and the slider 22 to slide downward, so that the connecting plate 24 drives the shovel plate 25 to move downward and abut against the road surface, so as to flatten the raised particles on the road surface and reduce the wear of the wear-resistant protective cloth 17; when the piston block 6 slides toward the direction away from the air bag 5, the first rod body 1111, the second rod body 1112 and the connecting rod 21 drive the slider 22 to move the shovel plate 25 upward and separate from the road surface, which helps to move the paver body 1.

[0055] The implementation principle of the embodiment of the present application is as follows: when working, the paver body 1 is moved to the construction road surface, and the hanging ring 9 is removed from the hook 8. At this time, the spring 71 pushes the piston block 6 to slide in the direction close to the air bag 5. Since the amount of air between the piston block 6 and the air bag 5 is constant, the air is pushed into the air bag 5, causing the air bag 5 to swell and abut against the road surface; when the piston block 6 slides in the direction close to the air bag 5, the first rod body 1111 drives the second rod body 1112 to move downward, so that the transmission rod 112 drives the transmission plate 113 to rotate, and the connecting rod 21 drives the slider 22 to move downward, so that the rotating shaft 12 drives the partition 10 to rotate a certain angle in the direction close to the paver body 1, and the dividing rod 19 is rotated to be parallel to the plane where the baffle 3 is located. At this time, the second abutting block 153 pushes the first abutting block 152, so that the receiving plate 14 moves towards the partition 10. The shovel 25 moves downwards and flattens the raised particles on the road surface. The dividing rod 19 first separates the roots of the grass and trees from the road surface. Then, the grass and trees are pushed away from the paver body 1 during the movement of the partition 10, so that the grass and trees can smoothly transition to the side of the baffle 3 away from the mounting plate 2, making it difficult for the baffle 3 to penetrate the grass and trees. During the movement, the grass leaves that fall from the partition 10 fall onto the receiving plate 14. The asphalt in the paver body 1 is sprayed out from the nozzle on the mounting plate 2, and the baffle 3 and the air bag 5 block the asphalt splashed out from the end nozzle, thereby reducing the asphalt splashing onto the grass and trees next to the construction road surface.

[0056] When the asphalt is paved, the pull rope 721 is pulled to make the hanging ring 9 on the pull rope 721 hang on the hook 8. At this time, the pull rope 721 pulls the piston block 6 to slide in the direction away from the air bag 5, causing the air bag 5 to be concave in the direction close to the piston block 6, and the air bag 5 is separated from the road surface; when the piston block 6 moves up, the partition 10 is driven by the first transmission member 11 to rotate in the direction away from the paver body 1, so that the second abutment block 153 and the first abutment block 152 are separated, and the torsion spring 151 drives the receiving plate 14 to rotate in the direction away from the partition 10, and the grass and leaves on the receiving plate 14 are poured out from the side of the partition 10 away from the paver body 1. At the same time, the second rod body 1112 drives the slider 22 and the shovel plate 25 to move upward through the connecting rod 21, so that the shovel plate 25 is separated from the road surface, which facilitates the movement of the paver body 1 when not paving asphalt.

[0057] The present application also discloses an asphalt pavement construction method. The asphalt pavement construction method uses the above-mentioned asphalt pavement construction equipment and further includes the following steps:

[0058] Step 1: Clean the road surface: clean up the debris on the construction road surface and level the road surface;

[0059] Step 2: Asphalt paving: Move the paver body 1 to the desired location, remove the hanging ring 9 from the hook 8, and the spring 71 pushes the piston block 6 to slide toward the direction close to the air bag 5, allowing air to enter the air bag 5. The air bag 5 expands and blocks the gap between the baffle 3 and the road surface. When the piston block 6 moves downward, the first transmission member 11 drives the partition 10 to rotate a certain angle toward the direction close to the paver body 1. At the same time, the second transmission member 15 drives the receiving plate 14 to rotate the required angle toward the direction close to the partition 10. When the paver body 1 moves forward, the asphalt in the paver body 1 is sprayed out through the nozzle on the mounting plate 2. The baffle 3 and the air bag 5 block the splashing asphalt. The partition 10 separates the grass and trees next to the construction road surface from the construction area.

[0060] Step 3: Compacting: Use a roller to compact the asphalt pavement;

[0061] Step 4: Water spraying: spray water on the asphalt layer for maintenance.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
