Description

Technical Field

[0001] This utility model belongs to the field of road paving devices, specifically, it relates to a highway asphalt pavement paving device. Background Technology

[0002] When laying asphalt pavement, a paving device is required to lay the pavement.

[0003] Patent application CN212000511U discloses a highway asphalt pavement paving device. Paragraph 0019 of the specification discloses that when asphalt falls onto the ground base, asphalt exceeding the thickness will move up along the surface of the shovel-shaped uniform material plate 812, preventing excess asphalt from moving from the top of the slope to the bottom of the slope, thus avoiding uneven asphalt thickness on the road surface before the roller compaction and ensuring the uniformity of the road surface paving.

[0004] In actual use, when adjusting the discharge size of the discharge pipe through the equalization plate, the extension of the equalization plate to one end of the discharge pipe will increase the movement range of the paving machine body. Therefore, when constructing in cracks with limited construction space, it is necessary to repeatedly adjust the position of the equalization plate to allow the asphalt in the discharge pipe to enter the crack, thus affecting the crack filling efficiency.

[0005] To address these shortcomings, a highway asphalt pavement paving device is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a highway asphalt pavement paving device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A highway asphalt pavement paving device includes a base, a receiving box is mounted on the base, a discharge port is opened on the first side of the receiving box away from the base, and two L-shaped plates are fixed on the first side of the receiving box, with L-shaped grooves opened on the opposite sides of the two L-shaped plates.

[0009] An adjusting plate is installed inside the discharge port. A connecting plate is fixed on the upper side of the adjusting plate. A first guide block is fixed on both sides of the connecting plate along the length of the discharge port. The end of the first guide block away from the connecting plate is located in the L-shaped groove. A blocking plate is fixed on the side of the adjusting plate close to the discharge port.

[0010] A threaded rod that fits into the adjusting plate.

[0011] Optionally, the first side of the adjusting plate away from the receiving box has a threaded hole that mates with the threaded rod, and a rotating cylinder is rotatably fitted on the first side of the adjusting plate, with the rotating cylinder sleeved on the threaded rod.

[0012] Optionally, a gear is fixed to the outer wall of the rotating cylinder, and two toothed plates mesh on the gear. The two toothed plates are symmetrically distributed along the radial direction of the gear and are located on both sides of the gear. A clamping plate is fixed to the end of the toothed plate away from the gear. Two second guide blocks are fixed to the first side of the adjusting plate. Guide grooves that slide with the clamping plate are opened on the opposite sides of the two second guide blocks.

[0013] Optionally, the first side of the receiving box is fixed with two locking blocks located below the L-shaped plate. The two locking blocks have slots on opposite sides, and the locking plate is set in correspondence with the slots. The two locking blocks are located on both sides of the receiving box, and the adjusting plate is located between the two locking blocks.

[0014] Optionally, a mixing tank is installed on the upper side of the base, and a discharge pipe is connected to the outer wall of the mixing tank. The end of the discharge pipe away from the mixing tank is located directly above the opening of the receiving box, and the discharge port is set in the length direction of the receiving box.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] The receiving box is used to hold paving materials such as asphalt, providing raw material storage space for paving operations. The L-shaped plate on the first side of the receiving box provides a supporting base for adjusting the adjusting plate. The discharge port is the channel for the material to flow out of the receiving box. The discharge port works with the adjusting plate. By changing its position at the discharge port, the adjusting plate directly adjusts the actual discharge speed of the discharge port, thereby controlling the amount of asphalt flowing out and adapting to the paving needs of different road surface cracks. The threaded rod works with the threaded adjusting plate to realize the positioning of the adjusting plate, which is convenient to adapt to different paving needs.

[0017] The fit between the limiting rod and the limiting groove restricts the rotation trajectory of the rotating cylinder, reducing deviation or wobbling during rotation. The through hole on the limiting rod matches the threaded rod, ensuring that the rotation of the rotating cylinder does not interfere with the threaded fit between the threaded rod and the adjusting plate, making the position adjustment and positioning processes of the adjusting plate independent of each other.

[0018] The guide slot of the second guide block slides into the clamping plate, limiting the movement trajectory of the clamping plate and reducing its deviation or tilting during movement, ensuring that the conical head at one end of the clamping plate can accurately slide into the clamping slot. The gear meshes with the symmetrically distributed toothed plates on both sides. When the gear is rotated, it can drive the two toothed plates and the clamping plate to move synchronously in opposite directions, making the clamping plate's fixing force on the adjusting plate uniform and consistent.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this embodiment provides a highway asphalt pavement paving device, including a base 1, a receiving box 4 is installed on the base 1, a discharge port 6 is opened on the first side of the receiving box 4 away from the base 1, and two L-shaped plates 7 are fixed on the first side of the receiving box 4, and L-shaped grooves 8 are opened on the opposite sides of the two L-shaped plates 7.

[0030] An adjusting plate 11 is installed in the discharge port 6. A connecting plate 17 is fixed on the upper side of the adjusting plate 11. A first guide block 18 is fixed on both sides of the connecting plate 17 along the length direction of the discharge port 6. The end of the first guide block 18 away from the connecting plate 17 is located in the L-shaped groove 8. A blocking plate is fixed on the side of the adjusting plate 11 close to the discharge port 6.

[0031] The threaded rod 13 is threaded within the adjusting plate 11.

[0032] Preliminary preparation: Place base 1 stably and fix material receiving box 4 on base 1;

[0033] Adjusting the size of the discharge port 6: According to the paving requirements, the worker moves the connecting plate 17, which slides away from the receiving box 4. The first guide blocks 18 on both sides of the connecting plate 17 will slide along the horizontal section of the L-shaped groove 8 on the L-shaped plate 7. The connecting plate 17 drives the blocking plate to slide out of the discharge port 6 through the adjusting plate 11. Then the connecting plate 17 slides upward, and the connecting plate 17 drives the first guide blocks 18 to slide from the horizontal section of the L-shaped groove 8 into the vertical section of the L-shaped groove 8. At this time, the distance between the blocking plate and the receiving box 4 is 0-1mm. According to the size of the crack, adjust the position of the first guide block 18 in the vertical section of the L-shaped groove 8 to adjust the position of the adjusting plate 11. Then, the adjusting plate 11 drives the blocking plate to adjust the opening size of the discharge port 6. Then, rotate the threaded rod 13. Since the threaded rod 13 is threadedly engaged with the adjusting plate 11, the height of the adjusting plate 11 relative to the discharge port 6 can be adjusted. One end of the threaded rod 13 abuts against one side of the receiving box 4, thereby completing the positioning of the adjusting plate 11 and maintaining the opening size of the discharge port 6. Then, push the base 1 above the crack. The paving material (such as asphalt) in the receiving box 4 will flow from the adjusted discharge port 6 to the crack, completing the paving operation at the road crack.

[0034] The receiving box 4 is used to hold paving materials such as asphalt, providing raw material storage space for paving operations. The L-shaped plate 7 on the first side of the receiving box 4 provides a supporting base for the adjustment plate 11. The discharge port 6 is the channel for the material to flow out of the receiving box 4. The discharge port 6 cooperates with the blocking plate. The adjustment plate 11 directly adjusts the actual discharge speed of the discharge port 6 by changing its position at the discharge port 6, thereby controlling the amount of asphalt flowing out and adapting to the paving needs of different road surface cracks. The threaded rod 13 is threadedly engaged with the adjustment plate 11 to realize the positioning of the adjustment plate 11, which is convenient to adapt to different paving needs.

[0035] In this embodiment, the first side of the adjusting plate 11 away from the receiving box 4 has a threaded hole 12 that engages with the threaded rod 13. A rotating cylinder 14 is rotatably fitted onto the first side of the adjusting plate 11, and the rotating cylinder 14 is sleeved on the threaded rod 13. A limiting groove is formed on the first side of the adjusting plate 11. A limiting rod is fixed at one end of the rotating cylinder 14 near the adjusting plate 11, and the other end of the limiting rod away from the rotating cylinder 14 is rotatably fitted into the limiting groove. A through hole adapted to the threaded rod 13 is formed on the limiting rod. When the operator rotates the rotating cylinder 14, the limiting rod at the end of the rotating cylinder 14 near the adjusting plate 11 rotates along the limiting groove on the first side of the adjusting plate 11, and the limiting rod rotates on the threaded rod 13 through the through hole. The engagement of the limiting rod and the limiting groove restricts the rotation trajectory of the rotating cylinder 14, reducing the deviation or shaking of the rotating cylinder 14 during rotation. The through hole on the limit rod is adapted to the threaded rod 13, so that the rotation of the rotating cylinder 14 does not interfere with the threaded engagement between the threaded rod 13 and the adjusting plate 11, and the position adjustment and positioning processes of the adjusting plate 11 are independent of each other.

[0036] In this embodiment, a gear 15 is fixed to the outer wall of the rotating cylinder 14. Two toothed plates 19 mesh on the gear 15. The two toothed plates 19 are symmetrically distributed along the radial direction of the gear 15 and are located on both sides of the gear 15. A clamping plate 16 is fixed to the end of the toothed plate 19 away from the gear 15. Two second guide blocks 20 are fixed to the first side of the adjusting plate 11. Guide grooves 21 that slide with the clamping plate 16 are opened on the opposite sides of the two second guide blocks 20. Two clamping blocks 9 located below the L-shaped plate 7 are fixed to the first side of the receiving box 4. A clamping groove 10 is opened on the opposite side of the two clamping blocks 9. A conical head is provided at the end of the clamping plate 16 near the clamping groove 10. The clamping plate 16 and the clamping groove 10 are correspondingly arranged. When the adjusting plate 11 needs to be moved, the operator rotates the rotating cylinder 14, and the gear 15 on the outer wall of the rotating cylinder 14 rotates synchronously. Since the gear 15 meshes with two toothed plates 19 symmetrically distributed along its radial direction, the rotation of the gear 15 will drive the toothed plates 19 on both sides to move, and the two toothed plates 19 will slide closer to each other. The retaining plate 16 at the end of the toothed plate 19 away from the gear 15 slides in the guide groove 21 of the second guide block 20, and one end of the retaining plate 16 slides into the retaining slot 10 of the retaining block 9 on the receiving box 4. With the threaded rod 13 and the threaded engagement of the adjusting plate 11, the adjusting plate 11 is positioned. The guide groove 21 of the second guide block 20 and the retaining plate 16 slide into each other, limiting the movement trajectory of the retaining plate 16, reducing the offset or tilting of the retaining plate 16 during movement, and allowing the conical head at one end of the retaining plate 16 to slide accurately into the retaining slot 10. Gear 15 meshes with toothed plates 19 symmetrically distributed on both sides. When gear 15 is rotated, it can drive the two toothed plates 19 and the clamping plate 16 to move synchronously in opposite directions, so that the clamping plate 16 has a uniform fixing force on the adjusting plate 11.

[0037] In this embodiment, a mixing tank 2 is installed on the upper side of the base 1. A discharge pipe 3 is connected to the outer wall of the mixing tank 2, with the end of the discharge pipe 3 furthest from the mixing tank 2 located directly above the opening of the receiving box 4. Before asphalt pavement paving, the material to be paved (such as asphalt) is placed in the mixing tank 2 on the upper side of the base 1. The mixing tank 2 mixes the material to reduce asphalt solidification. During operation, the material in the mixing tank 2 flows out through the discharge pipe 3 connected to its outer wall. Since the end of the discharge pipe 3 furthest from the mixing tank 2 is directly above the opening of the receiving box 4, the material falls into the receiving box 4. After collecting the material, the receiving box 4 completes the pavement paving operation through its discharge port 6. The mixing tank 2 can mix the material (such as asphalt) to reduce solidification or stratification during static storage, thus stabilizing the material. The discharge pipe 3 transports the mixed material from the mixing tank 2 to the receiving box 4. The outlet of the discharge pipe 3 is located directly above the opening of the receiving box 4, which allows the material to fall into the receiving box 4 and reduces the chance of the material spilling outside the receiving box 4.

[0038] In this embodiment, the discharge port 6 is located along the length of the receiving box 4, and two locking blocks 9 are located on both sides of the receiving box 4, with the adjusting plate 11 located between the two locking blocks 9. During paving operations, the paving material (such as asphalt) in the receiving box 4 flows out from the discharge port 6 located along its length to meet the paving requirements along the road length. When the paving operation is completed, the material in the discharge port 6 is first cleaned manually to reduce the accumulation of material and impurities in the discharge port 6. Since the adjusting plate 11 is located between the two locking blocks 9, and the two locking blocks 9 are fixed on both sides of the receiving box 4, when the operator rotates the rotating cylinder 14 to drive the gear 15 and the toothed plate 19, the locking plate 16 at the end of the toothed plate 19 can move from both sides of the adjusting plate 11 to the locking blocks 9 on both sides of the receiving box 4, and finally lock into the locking groove 10 of the locking block 9, thus completing the positioning of the adjusting plate 11. The position of the adjusting plate 11 between the two locking blocks 9 is limited. The blocking plate, together with its adjustment of the size of the discharge port 6, ensures that the size of the discharge port 6 does not change during operation, reducing the problem of uneven discharge caused by the shaking of the adjusting plate 11.

[0039] Working principle:

[0040] Step 1: Preliminary preparation: Place the base 1 stably. The base 1 can be a trolley. Ensure that the receiving box 4 is firmly fixed on the base 1.

[0041] Step 2, Material Preparation and Supply: Place the material to be paved (such as asphalt) into the mixing drum 2 on the upper side of the base 1. The mixing drum 2 will mix the material (such as reducing asphalt hardening). During operation, the material in the mixing drum 2 will flow out through the discharge pipe 3 connected to its outer wall. Since the end of the discharge pipe 3 away from the mixing drum 2 is located directly above the opening of the receiving box 4, the material will fall into the receiving box 4.

[0042] Step 3: Adjust the size of the discharge port 6: According to the paving requirements, rotate the rotating cylinder 14. The gear 15 on the outer wall of the rotating cylinder 14 rotates, and the gear 15 drives the meshing toothed plates 19 on both sides to slide closer to each other. The clamping plate 16 at the end of the toothed plate 19 slides in the guide groove 21 of the second guide block 20. One end of the clamping plate 16 slides out of the clamping groove 10 of the clamping block 9, releasing the positioning of the adjusting plate 11. The worker moves the connecting plate 17, causing the connecting plate 17 to slide away from the receiving box 4. The first guide blocks 18 on both sides of the connecting plate 17 slide along the transverse section of the L-shaped groove 8 on the L-shaped plate 7. The connecting plate 17 drives the blocking plate to slide out of the discharge port 6 through the adjusting plate 11. The worker then slides the connecting plate 17 upwards. The connecting plate 17 drives the first guide block 18 to slide from the transverse section of the L-shaped groove 8 into the vertical section. By adjusting the position of the first guide block 18 in the vertical section, the position of the adjusting plate 11 and the blocking plate are adjusted, thereby adjusting the opening size of the discharge port 6.

[0043] Step 4, Positioning Adjustment Plate 11: The operator rotates the threaded rod 13. Because the threaded rod 13 is threadedly engaged with the adjustment plate 11, the height of the adjustment plate 11 relative to the discharge port 6 is adjusted so that one end of the threaded rod 13 abuts against one side of the receiving box 4, thus completing the positioning of the adjustment plate 11.

[0044] Step 5, paving operation: Push the base 1 to the road crack, and the paving material in the receiving box 4 flows out from the adjusted discharge port 6 to complete the paving operation at the road crack.

[0045] Step 6, Post-operation cleanup: After the paving operation is completed, if the residue in the discharge port 6 affects the fit between the blocking plate and the discharge port 6, the residual material in the discharge port 6 can be cleaned.

[0046] When encountering multiple cracks in the same area, when filling smaller cracks, refer to step three above to adjust the opening of the discharge port 6 to a smaller size, and then refer to steps four and five to complete the paving operation at the crack. After the operation is completed, refer to step six to clean the residual material in the discharge port 6, and then move the blocking plate into the discharge port 6 to close the discharge port 6.

[0047] When filling larger cracks, similarly, refer to step three above to adjust the opening of the discharge port 6 to a larger size, and then refer to steps four and five to complete the paving operation at the crack; after the operation is completed, refer to step six to clean the residual material in the discharge port 6, and then move the blocking plate into the discharge port 6 to close the discharge port 6.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
