[0002] Rock and soil blasting is the blasting of rock and soil. Its main purpose is to remove obstacles by blasting. It is widely used in projects such as road construction. After the blasting is completed, there are usually many rock and soil fragments at the blasting location. In order to facilitate cleaning, conveyor belts are usually used to transport the fragments to the designated location and then transported away by means of transportation.

[0003] At present, most conveyor belts used for rock and soil transportation directly place the rock and soil on the surface of the conveyor belt for transportation. However, when transporting larger fragments, if the fragments are located off the center, they are easy to fall off the conveyor belt due to the shaking of the conveyor belt during transportation, so that subsequent staff need to clean up the fallen larger fragments, which is time-consuming and laborious.

By setting the jacks 16, the jacks 16 can push the connecting columns 12 to rise, thereby changing the angle of the conveyor belt 1, and the jacks 16 are fixed by setting the fixing rods 15.

[0023] like Figure 3 As shown, a square through hole 18 is formed at the top of the fixing frame 2 and near one side, and a mounting plate 19 is rotatably connected to the bottom of the fixing frame 2 and located at the position of the square through hole 18. A scraper 20 is fixedly connected inside the mounting plate 19, and the top of the scraper 20 is in close contact with the outer surface of the conveyor belt 1. By setting the scraper 20, the surface of the conveyor belt 1 can be cleaned, and by setting the fixing frame 2, the scraper 20 can be fixed.

[0024] like Figure 3 As shown, an adjustment plate 21 is fixedly connected to the bottom end of the fixing frame 2, a screw rod 22 is internally threadedly connected to the adjusting plate 21, one end of the screw rod 22 is rotatably connected to a pull rope 23, both ends of the pull rope 23 are fixedly connected to one side of the mounting plate 19, and by setting the screw rod 22, the rotation angle of the fixing frame 2 can be adjusted so that the scraper 20 can be in closer contact with the surface of the conveyor belt 1.

[0025] like Figure 1 and Figure 2 As shown, a plurality of mounting grooves 10 are provided on one side of the two centering plates 6, and rollers 11 are rotatably connected inside the plurality of mounting grooves 10.
