SBS modified asphalt can significantly improve the high-temperature stability, low-temperature crack resistance, and fatigue resistance of asphalt pavements, thereby extending the service life of the pavement. And the paving quality of SBS modified asphalt depends to a large extent on the performance of the paving device. At present, the common SBS modified asphalt paving devices on the market have certain limitations when facing roads with different widths.

[0028] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] As Figures 1 to 10 shown, a paving device for SBS modified asphalt of the present invention includes a locomotive 10. An installation box 20 is connected to the locomotive 10. A first rotating shaft 21 is rotatably connected to one side of the installation box 20. A first spiral distributor 22 is connected to the first rotating shaft 21. Both ends of the first rotating shaft 21 are connected with first rotating blocks 23. A first connecting card slot 231 is formed on one side of each first rotating block 23. A storage rack 30 is installed inside the installation box 20. A plurality of extended spiral distributor structures 31 are arranged inside the storage rack 30. The extended spiral distributor structures 31 can be connected to the first rotating shaft 21, and each extended spiral distributor structure 31 can be connected to each other. The extended spiral distributor structures 31 are used to increase the length of the cloth. A screed 40 is installed on the side of the installation box 20 away from the locomotive 10. Two extension frames 50 are arranged on the side of the installation box 20 away from the locomotive 10. A plurality of extended screed structures are connected to each extension frame 50. The extended screed structures are used to increase the range of leveling asphalt. An extension frame fixing structure is arranged between the installation box 20 and the extension frame 50. The extension frame fixing structure is used to adjust the position of the extension frame 50. A baffle 51 and a clamping and positioning plate 52 are connected to the end of each extension frame 50. A clamping fixing piece is connected to each clamping and positioning plate 52. The clamping fixing piece is used to connect the extended spiral distributor structure 31 and the first rotating block 23.

[0030] In the process of paving SBS modified asphalt, if the width of the road surface to be paved is greater than the length of the spiral distributor 22, a suitable number of extended spiral distributor structures 31 are selected according to the width of the road surface. First, one extended spiral distributor structure 31 is connected to the rotating block 23, and then the extended spiral distributor structures 31 are connected to each other. The position of the clamping positioning plate 52 is adjusted by adjusting the position of the extension frame 50, so that the clamping fixing part is connected to the extended spiral distributor structure 31 at the end. When the position of the extension frame 50 is adjusted, the extended vibrating ruler structure moves accordingly. Finally, the extension frame 50 is fixed by the extension frame fixing structure, thereby fixing the clamping positioning plate 52 and then fixing the extended spiral distributor structure 31. The connecting operation between multiple extended spiral distributor structures 31 and the connecting operation between an extended spiral distributor structure 31 and a rotating block 23 is formed. At this time, the extended vibrating ruler structure is fixed in a suitable position, and then the extended spiral distributor structure 31 and the spiral distributor 22 can be used together to carry out the spreading operation, and the vibrating ruler 40 and the extended vibrating ruler structure can be used to level the SBS modified asphalt after spreading. In this process, the baffle 51 is used to avoid blocking the SBS modified asphalt transported by the extended spiral distributor structure 31, so that the SBS modified asphalt is limited to the area formed by the two baffles 51, so that a longer SBS modified asphalt can be paved according to the road width, thereby reducing the number of round trips for paving and improving the efficiency of paving the SBS modified asphalt.

[0031] like Figure 3 , Figure 5 , Figure 9 and Figure 10 The extended spiral distributor structure 31 includes a rotating shaft 2 32, one end of the rotating shaft 2 32 is fixedly connected to a connecting block 1 33, the other end of the rotating shaft 2 32 is fixedly connected to a mounting block 34, a side of the mounting block 34 away from the rotating shaft 2 32 is provided with a connecting slot 2 341, the rotating shaft 2 32 is connected to a spiral distributor 2 35, the connecting block 1 33, the connecting slot 2 341 and the connecting slot 1 231 are all in the shape of a cross, the connecting slot 2 341 and the connecting slot 1 231 are both adapted to the size of the connecting block 1 33, and the positions of the connecting block 1 33 and the connecting slot 2 341 correspond.

[0032] When connecting an extended spiral distributor structure 31 to the first rotating block 23, insert the first connecting block 33 into the inside of the first connecting slot 231. When connecting two extended spiral distributor structures 31, insert the first connecting block 33 on one extended spiral distributor structure 31 into the inside of the second connecting slot 341 on the other extended spiral distributor structure 31. Then, connect the clamping and fixing member to the extended spiral distributor structure 31 at the end. After fixing the extension frame through the extension frame fixing structure, complete the operation of connecting the extended spiral distributor structure 31 and the first rotating block 23.

[0033] It should be noted that multiple second spiral distributors 35 have two opposite helix directions, and the first spiral distributor 22 also has two opposite helix directions. Through the second spiral distributor 35 and the first spiral distributor 22, the SBS modified asphalt can be better spread to both sides of the road.

[0034] Such as Figure 6 and Figure 7 , the clamping and fixing member includes a rotating seat 53 rotatably connected to the clamping and positioning plate 52. A second connecting block 54 is fixedly connected to the side of the rotating seat 53 away from the clamping and positioning plate 52. The shape of the second connecting block 54 is cross-shaped, and the size of the second connecting block 54 is adapted to the second connecting slot 341.

[0035] After connecting multiple extended spiral distributor structures 31, drive the second connecting block 54 to move by the clamping and positioning plate 52, and insert the second connecting block 54 into the inside of the second connecting slot 341 on the extended spiral distributor structure 31 at the end, and make the rotating seat 53 fit with the first rotating block 23. After fixing the extension frame through the extension frame fixing structure, the second connecting block 54 is stably inserted into the inside of the second connecting slot 341, connecting the rotating seat 53 and the first rotating block 23. At this time, as the extended spiral distributor structure 31 rotates, the rotating seat 53 and the second connecting block 54 rotate accordingly.

[0036] Such as Figure 3 and Figure 7 , a guiding and supporting component is arranged between the installation box 20 and the extension frame 50. The guiding and supporting component is used to make the extension frame 50 move along the length direction of the installation box 20. The guiding and supporting component includes a supporting guide rail 24 connected to the installation box 20 and a guiding sliding groove 501 opened on the extension frame 50. The supporting guide rail 24 is located inside the guiding sliding groove 501, and the extension frame 50 is slidably connected to the supporting guide rail 24 through the guiding sliding groove 501. The shapes of the supporting guide rail 24 and the guiding sliding groove 501 are both T-shaped.

[0037] When adjusting the position of the extension frame 50, the extension frame 50 can only move along the length direction of the installation box 20 through the support guide rail 24 and the guide chute 501, and the situation that the extension frame 50 is separated from the installation box 20 can be avoided during the movement.

[0038] As Figure 3 , Figure 6 and Figure 7 , the extension frame fixing structure includes a fixing plate 25 connected to the installation box 20 and a plurality of fixing jacks 502 opened on the top side of the extension frame 50. A plurality of fixing threaded holes 251 are opened on one side of the fixing plate 25. A fixing bolt 26 is threadedly connected to the inner wall of the fixing threaded hole 251, and the fixing bolt 26 is inserted into the interior of the fixing jack 502.

[0039] After moving the extension frame 50 to a suitable position, the positions of the fixing jack 502 and the fixing threaded hole 251 are made to correspond, and then the fixing bolt 26 is threadedly connected to the fixing threaded hole 251 and the fixing bolt 26 is inserted into the interior of the fixing jack 502, thereby fixing the extension frame 50 and making the position of the extension frame 50 no longer move.

[0040] It should be noted that the distance between two adjacent fixing jacks 502 and two adjacent fixing threaded holes 251 is the same, and the number of fixing bolts 26 is selected according to the requirements during use.

[0041] As Figure 1 , Figure 6 , Figure 7 and Figure 8 , the extension vibrating screed structure includes a mounting seat 60 connected to the extension frame 50. A pressing spring 61 is fixedly connected to one side of the mounting seat 60. The bottom end of the pressing spring 61 is fixedly connected to an extension vibrating screed 62. The top end of the extension vibrating screed 62 is fixedly connected to a guide rod 63 having a T-shaped cross-section. The guide rod 63 passes through the mounting seat 60 and is slidably connected to the mounting seat 60. A connection transmission component is arranged on the extension vibrating screed 62, and the connection transmission component is used for transmitting vibration between a plurality of extension vibrating screeds 62.

[0042] The connection transmission component includes a connection slot one 621 and a receiving slot 622 opened on the top side of the extension vibrating screed 62. A limiting rod 64 and a connection spring 65 are fixedly connected to the inner wall of the receiving slot 622. A connection plug 66 connected to the connection spring 65 is slidably connected to the outer surface of the limiting rod 64. The connection plug 66 is located inside the receiving slot 622 and is slidably connected to the receiving slot 622. The connection plug 66 is adapted to the size of the connection slot one 621, and the connection plug 66 corresponds to the position of the connection slot one 621.

[0043] In the normal state, the extended screed 62 is in contact with the top side of the screed 40, and the compression spring 61 is in a compressed state. The connecting plug 66 on one extended screed structure is inserted into the inner part of the connecting slot 621 on another extended screed 62. When adjusting the position of the extension frame 50, the mounting seat 60 drives the extended screed 62 to move. When the end of the extended screed 62 is about to move to a position separated from the screed 40, the connecting plug 66 is pulled to retract it into the receiving groove 622, and then the extension frame 50 is continued to be moved. After the extended screed 62 is separated from the screed 40, the extended screed 62 moves downward under the action of the compression spring 61. When the position of the extended screed 62 is stable, the bottom side of the extended screed 62 and the bottom side of the screed 40 are on the same horizontal plane. At this time, the SBS modified asphalt can be vibrated and leveled by the extended screed 62 and the screed 40 together, so as to lay the SBS modified asphalt flat, enabling the paving device to adjust the paving length.

[0044] It should be noted that when connecting an extended spiral feeder structure 31, one extended screed 62 is separated from the screed 40, and the remaining extended screeds 62 are still in contact with the screed 40.

[0045] Such as Figure 6 , two connecting slots 401 are provided on the top side of the screed 40. The position of the connecting plug 66 corresponds to that of the connecting slot 401, and the size of the connecting plug 66 is adapted to that of the connecting slot 401.

[0046] After pulling the connecting plug 66 to retract it into the receiving groove 622, the connecting spring 65 is in a compressed state. After the extended screed 62 is separated from the screed 40, the position of the connecting plug 66 corresponds to that of the connecting slot 401. At this time, the connecting plug 66 can be released, and the connecting plug 66 is inserted into the inner part of the connecting slot 401 under the reaction force of the connecting spring 65. A connection relationship is formed between the screed 40 and the extended screed 62 through the connecting plug 66, enabling the vibration on the screed 40 to be better transmitted to the extended screed 62. And when two or more extended screeds 62 are separated from the screed 40, a connection relationship is formed between adjacent two extended screeds 62 through the connecting plug 66 and the connecting slot 621, enabling the vibration to be better transmitted between adjacent two extended screeds 62, and further making the paving effect of the SBS modified asphalt better.

[0047] Such as Figure 3 And Figure 4, a driving component is provided on the installation box 20. The driving component is used to drive the rotation of the first rotating shaft 21. The driving component includes a driving motor 27 installed on the installation box 20. The output end of the driving motor 27 is connected with a first pulley 28. The first pulley 28 is connected with a second pulley 29 through belt transmission. The second pulley 29 is connected with the first rotating shaft 21.

[0048] When performing the fabricating operation on the SBS modified asphalt, start the driving motor 27. Under the driving action of the first pulley 28, the belt and the second pulley 29, the first rotating shaft 21 rotates, so that the first spiral fabricator 22 rotates. If an extended spiral fabricator structure 31 is connected to the first rotating block 23, at this time, the first rotating block 23 drives the extended spiral fabricator structure 31 to rotate, and the fabricating operation is jointly performed by the first spiral fabricator 22 and the extended spiral fabricator structure 31.

[0049] A vibration motor 41 is installed in the middle on one side of the screed 40. The vibration motor 41 is used to make the screed 40 vibrate, so that the screed 40 and the extended screed 62 can perform the screeding operation on the SBS modified asphalt.
