Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to asphalt surface layer paving and leveling construction equipment. Background Art

[0002] During long-term use of a road, defects such as dents and cracks may appear on its surface, requiring the road to be repaired. In the prior art, the damaged surface layer is generally removed, and then the asphalt surface layer is paved and leveled.

[0003] Road maintenance usually involves partial repairs of the road surface, with a relatively short length. Using large-scale pavers will increase costs and be inconvenient during construction.

[0004] Therefore, the paving and leveling of local asphalt surface layers mostly rely on manual operations, that is, transferring the asphalt to the road surface with a shovel and leveling it with a scraper. This operation method has the disadvantages of low efficiency and high labor intensity.

[0005] The prior art discloses an asphalt paving device (authorization announcement number: CN222043800U), in which asphalt is discharged to the construction area through a feed pipe and a discharge pipe, and the asphalt is scraped flat by a scraper plate. However, the device has the following problems:

[0006] First, when repairing the road surface, the width of the asphalt surface layer that needs to be spread may be different, and the above patent cannot adjust the width of the asphalt discharge.

[0007] Secondly, the asphalt is discharged through the feed pipe and the discharge pipe, causing most of the asphalt to be discharged near the feed pipe, making the asphalt unevenly distributed on the ground when it is discharged, making subsequent leveling difficult. Summary of the invention

One end of the conveying cylinder 43 is fixedly connected to the installation box 42. The upper part of the other end of the conveying cylinder 43 is rotatably connected to the bottom of the feeding pipe 44. The bottom of the conveying cylinder 43 is evenly provided with a first discharge port 46 along its length direction. A conveying shaft 47 is rotatably connected in the conveying cylinder 43. A spiral conveying blade 48 is fixedly connected to the conveying shaft 47.

[0071] A stirring mechanism, which is arranged in the scraper frame 24;

[0072] The driving mechanism is used to drive the conveying shaft 47 to rotate, drive the running wheel 21 to rotate, and drive the stirring mechanism to work.

[0073] Furthermore, the adjustment mechanism includes a double-headed screw 31 and a first motor 32. The double-headed screw 31 is rotatably connected between the front and rear side plates of the frame 11. A track rod 33 is fixedly connected to the frame 11 on the left side of the double-headed screw 31. A first ear seat 34 and a second ear seat 35 are fixedly connected to the positioning plate 2. The first ear seat 34 is slidably connected to the track rod 33. The second ear seats 35 on the front and rear sides are respectively engaged with the thread grooves on the front and rear sides of the double-headed screw 31 with opposite rotation directions. The first motor 32 is fixedly connected to the outer wall of the front side plate of the frame 11. The first motor 32 is used to drive the double-headed screw 31 to rotate.

[0074] Furthermore, a blanking shaft 17 is provided at the center of the blanking tube 13 , a spiral blanking blade 18 is fixedly connected to the blanking shaft 17 , a second motor 19 is fixedly connected to the top of the barrel 12 , and an output shaft of the second motor 19 is connected to the top of the blanking shaft 17 .

[0075] Furthermore, a seat plate 25 is fixedly connected to the left side of the scraper frame 24, and a suspension rod 26 is evenly slidably connected to the seat plate 25 along its length direction. A suspension seat 27 is fixedly connected to the top of the suspension rod 26, and a roller frame 28 is fixedly connected to the bottom of the suspension rod 26. A first spring 29 is sleeved on the suspension rod 26 between the roller frame 28 and the seat plate 25, and a pressure roller 210 is rotatably connected to the roller frame 28. A groove 211 is opened on the inner wall of the positioning plate 2, and the bottom of the groove 211 is inclined. The heads of the roller frame 28 and the pressure roller 210 extend into the groove 211.

[0076] In this embodiment, the device can be powered by a battery, gasoline or diesel generator, which will not be described in detail here.

[0077] like Figure 1 As shown, molten asphalt is added from the hopper 14 to the barrel 12. In the initial state, the two conveying barrels 43 are in an aligned state, and then the first motor 32 is started. The first motor 32 is a servo motor and drives the double-headed screw 31 to rotate. By controlling the direction of the first motor 32, the two positioning plates 2 can be brought close to each other. At the beginning, the sliding rod 16 can be slightly pushed to the left, so that the barrel 12 moves a little distance to the left, and then when the positioning plates 2 are close to each other, the barrel 12 can automatically move to the left.

[0078] like Figure 8-Figure 10 As shown, when the positioning plates 2 approach each other, the barrel 12 and the hanger 41 move to the left, the mounting box 42 rotates around its rotational connection position with the positioning plate 2, and the end of the conveying barrel 43 away from the mounting box 42 rotates around the feeding pipe 44, so that the conveying barrel 43 tilts to adapt to the distance between the positioning plates 2.

[0079] Then the second motor 19 drives the blanking shaft 17 and the blanking blade 18 to rotate, and the asphalt enters the conveying cylinder 43 through the blanking pipe 13 and the feeding pipe 44.

[0080] When the driving mechanism is working, it drives the walking wheel 21 to rotate, so that the device moves from left to right. The moving direction of the device can be adjusted by the steering wheel 23.

[0081] The driving mechanism also drives the conveying shaft 47 to rotate, and the conveying blades 48 rotate with the conveying shaft 47 to convey the asphalt in the conveying cylinder 43 toward the direction close to the positioning plate 2. In this application, the two conveying shafts 47 have the same direction of rotation, while the two conveying blades 48 have opposite rotation directions, and the asphalt falls from the first discharge port 46.

[0082] The positioning plate 2 can control the paving width of the asphalt. The scraper frame 24 scrapes the asphalt flat. The stirring mechanism is driven by the driving mechanism to stir the scraped asphalt to discharge the bubbles inside the asphalt. After the stirring is completed, Figure 19-20 As shown, the first spring 29 presses the pressure roller 210 toward the asphalt surface layer to flatten the stirred asphalt.

[0083] A groove 211 is provided so that there is an overlapping area between the pressure roller 210 and the positioning plate 2 to prevent the asphalt near the positioning plate 2 from being unable to be flattened. When the positioning plate 2 moves, its inner wall scrapes the two sides of the asphalt surface layer flat.

[0084] Example 2

[0085] The driving mechanism includes:

[0086] The drive box 61 has a movable groove 611 in the right side plate of the frame 11, the drive box 61 is slidably connected in the movable groove 611, and the drive box 61 is fixedly connected to the right end of the positioning plate 2, and a drive sleeve 612 is rotatably connected between the front and rear side plates of the drive box 61;

[0087] The driving motor 62 has a driving shaft 621 rotatably connected in the movable groove 611. The driving shaft 621 is slidably connected in the driving sleeve 612. The outer wall of the driving shaft 621 is fixedly connected with a driving rib 622. The inner wall of the driving sleeve 612 is provided with a driving groove 623.

[0088] The first rotating shaft 63 has a first cavity 631 formed above the through slot 45. The first rotating shaft 63 is rotatably connected to the positioning plate 2 and the left side plate of the driving box 61. The right end of the first rotating shaft 63 is linked to the driving sleeve 612 through the first bevel gear pair 632. The left end of the first rotating shaft 63 extends into the first cavity 631.

[0089] The second rotating shaft 64 is rotatably connected in the through slot 45. The top of the second rotating shaft 64 is linked to the left end of the first rotating shaft 63 through the second bevel gear pair 641. The top plate and the bottom plate of the installation box 42 are rotatably connected to the second rotating shaft 64. The second rotating shaft 64 is linked to the conveying shaft 47 through the third bevel gear pair 642.

[0090] Furthermore, a connecting rod 49 is hinged between the right side of the hanger 41 and the top of the positioning plate 2, the connecting rod 49 and the corresponding conveying cylinder 43 are parallel to each other, the hinge center of the connecting rod 49 and the positioning plate 2 is longitudinally flush with the center of the corresponding second rotating shaft 64, and the hinge center of the connecting rod 49 and the hanger 41 is longitudinally flush with the center of the corresponding feeding pipe 44.

[0091] This embodiment is different from Embodiment 1 in that this embodiment discloses the technical features of the driving mechanism.

[0092] like Figure 5-Figure 6 As shown, when the positioning plate 2 moves, it drives the driving box 61 to move. During the movement of the driving box 61, under the action of the driving groove 623 and the driving rib 622, the driving sleeve 612 always rotates with the driving shaft 621, the driving motor 62 drives the driving shaft 621 to rotate, the driving shaft 621 drives the driving sleeve 612 to rotate, and the driving sleeve 612 drives the first rotating shaft 63 to rotate through the first bevel gear pair 632.

[0093] like Figure 7-Figure 8 As shown, when the positioning plate 2 moves, the installation box 42 rotates around the second rotation axis 64.

[0094] The first rotating shaft 63 drives the second rotating shaft 64 to rotate through the second bevel gear pair 641 , and the second rotating shaft 64 drives the conveying shaft 47 and the conveying blade 48 to rotate through the third bevel gear pair 642 .

[0095] like Figure 5 As shown, the two third rotating shafts have the same direction of rotation, such as Figure 8 As shown, the two conveying shafts 47 have the same rotation direction, and the two conveying blades 48 have opposite rotation directions. The rotation direction of the driving motor 62 is set. When the conveying blades 48 rotate, the asphalt in the conveying cylinder 43 is conveyed toward the installation box 42.

[0096] like Figure 1 and Figure 3 As shown, when the positioning plate 2 moves, the positioning plate 2 can also pull the hanger 41 and the barrel 12 to move through the connecting rod 49, thereby improving the stability of the barrel 12 when moving.

A closing groove 733 is provided on the opening and closing roller 73 near the installation box 42, and a slot 734 is provided on the opening and closing roller 73 away from the installation box 42. The closing groove 733 is connected to one end of the slot 734 through a release groove 735, and the closing groove 733 is connected to the other end of the slot 734 through a push groove 736.

[0102] Furthermore, a fixing ring 81 is fixedly connected to the outer wall of the blanking tube 13, a connecting rod 82 is slidably connected to the fixing ring 81, a conical seat 83 is integrally fixedly connected to the bottom of the connecting rod 82, a hanging ring 84 is integrally fixedly connected to the top of the connecting rod 82, the hanging ring 84 is made of magnetic material, and an electromagnet 85 is fixedly connected to the outer wall of the blanking tube 13 above the hanging ring 84;

[0105] This embodiment is different from Embodiment 2 in that, on the one hand, this embodiment discloses the technical features of the opening and closing mechanism, on the other hand, discloses the unloading mechanism at the bottom of the unloading tube 13 , and also discloses the driving structure of the walking wheel 21 .

[0106] like Figure 8-Figure 10 ,as well as Figure 13-16 As shown, when the conveying shaft 47 rotates, the third rotating shaft 731 and the opening and closing roller 73 are driven to rotate through the first spur gear pair 732. In the initial state, the pin shaft 714 is located in the groove 733, and the second spring 724 is in a compressed state. At this time, the second discharge port 715 and the first discharge port 46 are staggered, and the semi-cylinder 71 closes the first discharge port 46. At this time, when the conveying blade 48 rotates, the asphalt is transported in the conveying cylinder 43 toward the mounting cylinder, and ensures that the conveying cylinder 43 is filled with asphalt.

[0107] When the pin shaft 714 moves to the position where the engagement groove 733 and the release groove 735 intersect, the second spring 724 is released, pushing the pin shaft 714 to move in the release groove 735 in the direction away from the installation box 42, and the pin shaft 714 drives the semi-cylinder 71 and the semi-circular sleeve 711 to move. When the pin shaft 714 reaches the intersection of the release groove 735 and the slot 734, the second discharge port 715 is aligned with the first discharge port 46, and the asphalt falls from the position of each first discharge port 46, and the opening and closing rollers 73 rotate. When the pin 714 moves in the slot 734, the first discharge port 46 is kept open. When the pin 714 moves to the intersection of the slot 734 and the push groove 736, the opening and closing roller 73 continues to rotate, and the pin 714 moves in the push groove 736, and the pin 714 box is moved closer to the installation box 42. The second spring 724 is compressed and the semi-cylinder 71 moves, and the second discharge port 715 is staggered with the first discharge port 46. Such a cycle can achieve intermittent and uniform material discharge.

[0108] like Figure 3-Figure 4 ,as well as Fig.18 As shown, when the first rotating shaft 63 rotates, the fourth rotating shaft 65 is driven to rotate through the worm gear pair 652, and the fourth rotating shaft 65 drives the axle 653 and the walking wheel 21 to rotate through the first transmission wheel 654 and the first belt 655, so as to realize the self-propelled device.

[0109] like Figure 10-12 ,as well as Fig.17 As shown, when the pin shaft 714 is located in the groove 733, the slide seat 721 contacts the two metal plates 87, the electromagnet 85 is energized to suck up the lifting ring 84, and the conical seat 83 closes the bottom of the drop tube 13. Conversely, when the pin shaft 714 slides out of the groove 733, the electromagnet 85 is de-energized, the conical seat 83 drops due to gravity, and the asphalt falls from the bottom of the drop tube 13, thereby solving the problem of no asphalt falling in the middle position of the two positioning plates 2.

[0110] The entire process of asphalt paving is: first, the first discharge port 46 is closed, and the asphalt falls in the drop tube 13. When the depth of the asphalt in the drop tube 13 reaches the intersection of the feed pipe 44 and the drop tube 13, the asphalt enters the conveying cylinder 43 through the feed pipe 44 and fills the conveying cylinder 43 under the action of the conveying blades 48. Then the first discharge port 46 is opened, and the bottom of the drop tube 13 is opened synchronously. The asphalt falls from the first discharge port 46 on the one hand, and falls from the bottom of the drop tube 13 on the other hand.

[0117] This embodiment is different from Embodiment 3 in that this embodiment discloses the technical features of a stirring mechanism to stir the asphalt so that the aggregate and binder in the asphalt are more tightly combined.

[0118] like Figure 3-Figure 4 , 19 and Figure 21-22 As shown, the axle 653 drives the synchronous shaft 52 to rotate through the second transmission wheel 662 and the second belt 663. Under the action of the second spur gear pair 66, the reciprocating shaft 53 rotates, and the reciprocating shaft 53 drives the transmission box 51 to move forward and backward through the reciprocating thread groove 531 thereon. During this process, the synchronous shaft 52 drives the synchronous sleeve 513 to rotate through the cooperation of the synchronous ribs 521 and the synchronous grooves 522. The synchronous sleeve 513 drives the installation shaft 514, the turntable 516 and the stirring shaft 517 to rotate through the fourth bevel gear pair 515. The stirring shaft 517 rotates on the one hand and moves back and forth on the other hand to stir the asphalt evenly.
