The first conveying mechanism is located above the second conveying mechanism. The asphalt raw material conveying device further includes a frame. The first conveying mechanism includes a first conveying roller and a first conveyor belt. The first conveying roller is rotatably connected to the frame; there are two first conveying rollers, and the two first conveying rollers are distributed along the conveying direction of the first conveying mechanism; a support member is vertically provided above the second conveying mechanism. The support member is located at the end of the first conveying mechanism, and the two support members are distributed on both sides of the conveying direction of the second conveying mechanism; a rotating roller is rotatably connected between the two support members, and the height of the rotating roller is located between the first conveying roller and the second conveying mechanism; the first conveyor belt is sleeved outside the rotating roller and the two first conveying rollers.

Detailed implementation manners

[0034] The following further Figures 1-6 describes the present application in detail with reference to the attached drawings.

[0035] Embodiment 1 of the present application discloses an asphalt raw material transportation device. Referring to Figure 1 and Figure 2 , the asphalt raw material transportation device includes a body 1. A rotating roller 11 is provided at each end of the body 1. One of the rotating rollers 11 is rotatably connected to the body 1, and moving blocks 12 are rotatably connected to both ends of the other rotating roller 11. The moving blocks 12 are slidably engaged with the body 1. A conveyor belt 13 is sleeved between the two rotating rollers 11.

[0036] Referring to Figure 2 , a tensioning component 2 is provided on the body 1. The tensioning component 2 includes a nut seat 21 and a tensioning screw 22. The nut seat 21 is fixedly connected to the moving block 12. The tensioning screw 22 is rotatably connected to the body 1. One end of the tensioning screw 22 passes through the nut seat 21 and is threadedly engaged with the nut seat 21. The other end of the tensioning screw 22 is threadedly engaged with a mounting head 221. The end of the mounting head 221 is hexagonal. A mounting pin 222 is inserted into the tensioning screw 22. The mounting pin 222 passes through the mounting head 221 and is in interference fit with the mounting head 221.

[0037] When tensioning the conveyor belt 13, the staff uses a tool to rotate the mounting head 221 to rotate the tensioning screw 22, and the nut seat 21 moves, driving the moving block 12 to move, so as to adjust the position of the rotating roller 11, achieving the effect of tensioning the conveyor belt 13.

[0038] Referring to Figure 1 and Figure 4, a rotating seat 3 is hinged on the body 1, and an adjusting assembly 4 is arranged between the rotating seat 3 and the body 1. The adjusting assembly 4 includes an adjusting motor 41, an adjusting seat 42, a connecting rod 43 and a swing plate 44. Both the adjusting motor 41 and the adjusting seat 42 are installed on the rotating seat 3. A rotating shaft is rotatably connected to the adjusting seat 42, and the adjusting motor 41 is coaxially connected to the rotating shaft. One end of the swing plate 44 is fixedly connected to the rotating shaft, and a driving groove 441 is formed on the swing plate 44. The connecting rod 43 is fixedly connected to the body 1, and one end of the connecting rod 43 is connected with a moving seat 431 through a bearing. The moving seat 431 is slidably fitted in the driving groove 441. The cooperation between the moving seat 431 and the bearing makes the movement of the connecting rod 43 smoother and more stable.

[0039] When adjusting the angle of the body 1, the operator starts the adjusting motor 41 to rotate the rotating shaft, driving the swing plate 44 to rotate, so as to push the connecting rod 43 and make the body 1 rotate, achieving the effect of adjusting the angle of the body 1.

[0040] Refer to Figure 4 , in order to facilitate the movement of the body 1 by a crane, anti-collision pipes 14 are welded on both sides of the body 1. The anti-collision pipes 14 are hollow pipes. On the one hand, the anti-collision pipes 14 facilitate the sleeving of the lifting ropes, and on the other hand, they can reduce the impact on the body 1 through their stress deformation.

[0041] The implementation principle of the asphalt raw material transportation device in Embodiment 1 of this application is: when adjusting the angle of the body 1, the operator starts the adjusting motor 41 to rotate the rotating shaft, driving the swing plate 44 to rotate, so as to push the moving seat 431 and make the connecting rod 43 move, achieving the effect of adjusting the angle of the body 1.

[0042] When tensioning the conveyor belt 13, the operator uses a tool to rotate the mounting head 221 to make the tensioning screw 22 rotate, and the nut seat 21 moves, driving the moving block 12 to move, so that the rotating roller 11 presses on the conveyor belt 13, achieving the effect of tensioning the conveyor belt 13.

[0043] The operator adjusts the angle of the body 1 by using the adjusting assembly 4. The transportation device can adapt to the transportation requirements of different equipment heights, and there is no need to carry out a stabilizing operation on the body 1. Compared with the prior art, the operation steps of the transportation device are reduced, and the applicability of the transportation device is improved.

[0044] Embodiment 2: The difference between this embodiment and Embodiment 1 lies in the different structures of the tensioning assembly 2 and the conveyor belt 13.

[0045] Refer to Figure 5, the tensioning assembly 2 includes a sliding seat 23, a sliding rod 24, and a first pressing spring 25. The sliding rod 24 is connected to the machine body 1 and is parallel to the moving direction of the moving block 12. The sliding seat 23 is fixedly connected to the moving block 12. The sliding rod 24 passes through the sliding seat 23 and is slidably engaged with the sliding seat 23. The first pressing spring 25 is sleeved on the sliding rod 24 and is located between the two rotating rollers 11.

[0046] Referring to Figure 5 and Figure 6 , a reverse resistance assembly 5 is provided between the sliding seat 23 and the machine body 1. The reverse resistance assembly 5 includes a moving rod 51, a fixed toothed ring 52, and a second pressing spring 53. A fixed plate is fixedly connected to the machine body 1. The moving rod 51 is slidably engaged with the fixed plate. A connecting plate 511 is fixedly connected to the moving rod 51. The second pressing spring 53 is sleeved on the moving rod 51 and is located between the connecting plate 511 and the fixed plate. A contact inclined surface is provided at one end of the moving rod 51 close to the sliding seat 23. A plurality of fixed toothed rings 52 are fixedly connected to the sliding seat 23. The cross-section of the fixed toothed ring 52 is arranged in a right-angled triangle, and the plane of the fixed ring faces the first pressing spring 25. The contact inclined surface contacts the arc inclined surface of the fixed toothed ring 52.

[0047] When tensioning the conveyor belt 13, the staff uses the first pressing spring 25 to press the sliding seat 23 to keep the rotating roller 11 in a pressing state against the tensioning roller, and the conveyor belt 13 always maintains a certain tension; when preventing the rotating roller 11 from moving in the reverse direction, the side wall of the moving rod 51 fits the plane of the fixed toothed ring 52; when the rotating roller 11 is pressed and moves, the fixed toothed ring 52 presses the contact inclined surface to move the moving rod 51 to avoid the fixed toothed ring 52, and the second pressing spring 53 is compressed. After the moving rod 51 passes the fixed toothed ring 52, the moving rod 51 moves in the reverse direction under the action of the second pressing spring 53 and resets to maintain the state of fitting the plane of the fixed toothed ring 52.

[0048] Referring to Figure 5 , in order to improve the conveying efficiency of the conveyor belt 13, a plurality of material blocking rods 131 are fixedly connected to the surface of the conveyor belt 13. The material blocking rods 131 are uniformly distributed along the circumferential direction of the conveyor belt 13. The material blocking rods 131 are used to block the movement of the asphalt material.

[0049] The above are all the preferred embodiments of this application. The protection scope of this application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
