[0002] Infrastructure construction is the foundation of economic development. In road and bridge construction, loaders will be used whenever large amounts of construction materials are involved in transportation and loading and unloading.

[0003] The existing utility model with authorization announcement number CN221295012U discloses a road and bridge construction loading machine, in which a two-layer conveyor belt with adjustable angle is set at the front end of the conveyor belt to facilitate the adjustment of the matching relationship between the conveyor belt and the transport vehicle, so that the raw materials can enter the transport vehicle at a more appropriate angle. Although the above technical solution can enable the raw materials to enter the transport vehicle at a more appropriate angle, the width of the discharge position space is fixed, and the feed opening sizes of different loading structures are different. There is a lack of an adjustment structure that can adjust the discharge width, resulting in poor adaptability and limiting its application scenarios. To this end, we propose a road and bridge construction loading machine to solve the above problems. Utility Model Content

[0020] A loading machine for road and bridge construction includes a pallet truck 1. A conveying mechanism 2 is provided above the pallet truck 1. A fixed block 3 and a button controller 11 are fixedly connected to the upper surface of the pallet truck 1. The inner wall of the fixed block 3 is rotatably connected to the inner wall of the conveying mechanism 2. A hydraulic rod 14 is movably hinged on the upper surface of the pallet truck 1. The telescopic end of the hydraulic rod 14 is fixedly connected to a movable block 15. Both ends of the movable block 15 are rotatably connected to the bottom of the conveying mechanism 2. By setting the hydraulic rod 14, it can be telescoped to control the height of the movable block 15, thereby controlling the inclination angle of the conveying mechanism 2.

[0021] The bottom surface of the conveying mechanism 2 is fixedly connected to the expansion frame 4, and the inner wall of the expansion frame 4 is fixedly connected to the dual-axis motor 5. The conveying mechanism 2, the dual-axis motor 5 and the hydraulic rod 14 are all electrically connected to the button controller 11 through wires. The back of the pallet trolley 1 is fixedly connected to two connecting rods 12, and each connecting rod 12 is fixedly connected to a pull ring 13 at one end away from the pallet trolley 1. By setting the connecting rod 12, the pull ring 13 and the pallet trolley 1 can be connected, and then the external dragging mechanism can pull the pull ring 13 through a rope to pull the entire loader.

[0022] The two output ends of the dual-axis motor 5 are fixedly connected to the threaded rod 6, the outer surface of each threaded rod 6 is threadedly connected to the movable plate 7, the inner wall of each movable plate 7 is threadedly connected to the outer surface of the threaded rod 6, and the outer surfaces of the two output ends of the dual-axis motor 5 are fixedly connected to the coupling 16, and the output end of each coupling 16 is fixedly connected to the outer surface of the threaded rod 6. By setting the coupling 16, the connection between the output end of the dual-axis motor 5 and the threaded rod 6 can be strengthened, thereby increasing the rotational stability of the threaded rod 6.

[0023] The upper surface of each movable plate 7 is fixedly connected to an extension plate 8, and the upper surface of each extension plate 8 is fixedly connected to a connecting plate 9. The inner wall of the expansion frame 4 is fixedly connected to two auxiliary bearings 17, and the inner ring of each auxiliary bearing 17 is fixedly connected to the outer surface of the threaded rod 6. By setting the auxiliary bearings 17, the expansion frame 4 and the threaded rod 6 can be connected, thereby increasing the smoothness of the rotation of the threaded rod 6.

[0024] The upper surface of each connecting plate 9 is fixedly connected to an adjustment limit plate 10, the bottom surface of each adjustment limit plate 10 is in contact with the upper surface of the conveying mechanism 2, and the bottom surface of each movable plate 7 is fixedly connected to a limit slider 18. The outer surface of each limit slider 18 is slidably connected to the interior of the expansion rack 4. By setting the limit slider 18, it can slide inside the expansion rack 4, thereby increasing the stability of the two movable plates 7 when they approach or move away from each other.

[0025] When in use, the entire loader can be dragged and moved by wrapping the two pull rings 13 with a rope structure such as a chain of an external towing mechanism. When the inclination angle of the conveying mechanism 2 needs to be adjusted, the operation button controller 11 controls the hydraulic rod 14 to be energized and extended, and then the pitch angle of the conveying mechanism 2 will change under the movable hinge between the hydraulic rod 14 and the pallet truck 1, the movable block 15 and the conveying mechanism 2, and the fixed block 3 and the conveying mechanism 2. When the conveying mechanism 2 needs to be used for loading, the operation controls the conveying mechanism 2 to convey the materials required for road and bridge construction from low to high. When the discharge width at the top of the conveying mechanism 2 needs to be adjusted, the operation button controller 11 controls the dual-axis motor 5 to be energized to drive the two threaded rods 6 to rotate, and then the two movable plates 7 approach or move away from each other. At the same time, under the connection of the extension plate 8 and the connecting plate 9, the two adjustment limit plates 10 approach or move away from each other, thereby adjusting the discharge width at the top discharge port position of the conveying mechanism 2, so as to adapt to charging structures with different feed opening sizes. The invention effectively solves the problem that the device is inconvenient to cope with different sizes of feed openings of different charging structures due to the lack of an adjustment structure capable of adjusting the discharge width.
