A second motor 21 is fixedly connected to the front side of the right telescopic plate 14, and the output end of the second motor 21 penetrates the telescopic plate 14 and is fixedly connected to the right driving roller 20. A fixed cylinder 22 is fixedly connected to the bottom of the connecting seat 11. The fixed cylinder 22 is arranged on the left side of the first motor 19. An electric push rod 23 is fixedly connected in the fixed cylinder 22. The telescopic frame 24 can be driven to telescopically move in the fixed cylinder 22 through the electric push rod 23. The output end of the electric push rod 23 is fixedly connected to the telescopic frame 24. An auxiliary roller 25 is rotatably connected in the telescopic frame 24, which plays a transmission effect. Belts 26 are arranged on the outsides of the driving rollers 20 and the auxiliary rollers 25, which can convey materials.

[0034] Referring to Figure 2 , the lifting component includes support plates 2. The bottoms of the two support plates 2 are both fixedly connected to the moving seat 1. A bidirectional threaded rod 3 is penetrated and rotatably connected between the two support plates 2. Moving blocks 5 are threadedly connected to the outer sides of both sides of the bidirectional threaded rod 3. Movable frames 6 are rotatably connected to the opposite sides of the two moving blocks 5. A lifting plate 7 is arranged above the bidirectional threaded rod 3. A connecting frame 8 is fixedly connected to the bottom of the lifting plate 7. The outside of the connecting frame 8 is rotatably connected to the movable frame 6. The top of the lifting plate 7 is fixedly connected to the lifting frame 10.

[0036] Working principle: During operation, the device as a whole is moved to the required position through the universal wheels at the bottom of the moving seat 1. The concrete material is placed on the belt 26. The second motor 21 is started to drive the driving roller 20 to rotate, which cooperates with the auxiliary roller 25 to drive the belt 26 to move and convey the material. When it is necessary to adjust the length of the belt 26, the first motor 19 is started to drive the gear 18 to rotate. Through the meshing connection, the two rack plates 16 are driven to move away from each other, so that the two telescopic plates 14 are driven by the rack plates 16 to extend from both sides of the connecting seat 11. At the same time, the electric push rod 23 is started to drive the telescopic frame 24 to contract and retract into the fixed cylinder 22 to adjust the conveying length of the belt 26 and keep the belt 26 always in a taut state.
