[0026] The adjustment mechanism 2 includes a first mounting frame 21 and a second mounting frame 22. The first mounting frame 21 has a hole in the middle section and a nut seat 211 is embedded and installed. The second mounting frame 22 has a hole in the middle section and a bearing seat 221 is embedded and installed. The upper end surfaces of the first mounting frame 21 and the second mounting frame 22 are fixedly connected to the bottom of the first frame 11 and the second frame 12 respectively.

[0027] A screw rod 23 is rotatably installed in the bearing seat 221 , and a rear end of the screw rod 23 is threadedly connected to the nut seat 211 . The rear end of the screw rod 23 passes through the nut seat 211 and is fixedly installed with a hand wheel 231 .

[0028] Specifically, the adjustment mechanism 2 is the core component of the loader and allows the length of the vehicle body 1 to be adjusted to accommodate the loading of building materials of varying sizes. The adjustment mechanism 2 includes a first mounting bracket 21 and a second mounting bracket 22, which are fixedly connected to the first and second frames 11, 12, respectively. A nut seat 211 and a bearing seat 221 are embedded in the first and second mounting brackets 21, 22, respectively, providing fixed connection points for the screw rod 23. The design of the nut seat 211 and the bearing seat 221 allows the screw rod 23 to rotate freely within them, thereby adjusting the length of the vehicle body 1. The screw rod 23 is a key transmission component, with its rear end passing through the nut seat 211 and affixed to a handwheel 231. By rotating the hand wheel 231, the screw rod 23 can be conveniently driven to rotate in the nut seat 211, thereby changing the distance between the second frame 12 and the first frame 11 on the opposite side. The hand wheel 231 is the part directly operated by the operator. By rotating the hand wheel 231, the rotation and rotation direction of the screw rod 23 can be conveniently controlled, thereby adjusting the length of the vehicle body 1. The design of the hand wheel 231 makes the operation more labor-saving and convenient.

[0029] The extension frame 121 is mounted on the outer rear end of the second frame 12, with its inner wall contacting the outer front end of the first frame 11. This design allows the second frame 12 to be adjusted in length via the extension frame 121 without being fixedly connected to it, to accommodate building materials of varying lengths. The rigidity of the extension frame 121 also enhances the service life of the vehicle body 1. This design allows this building material loader to accommodate a wide variety of building material sizes and materials, reducing restrictions on material type. Furthermore, the length of the vehicle body 1 can be adjusted by operating the screw 23 via the handwheel 231, making operation more convenient and safer, reducing operational difficulty and safety risks.

[0030] Example 2

[0031] In order to facilitate the movement of the vehicle body, Figure 2 and Figure 3 As shown, in this embodiment, a pusher frame 111 is fixedly mounted at the rear end of the first frame 11, and the lower end surface of the first frame 11 is flush with the lower end surface of the second frame 12. In this design, the pusher frame 111 is fixedly mounted at the rear end of the first frame 11.

This design ensures that the loader remains stable even on uneven ground. The 135-degree angle between the front end and the bottom of the second frame 12 helps improve the loader's maneuverability, allowing it to more easily cross obstacles, while also providing better maneuverability during pushing and facilitating unloading operations.

[0033] Example 3

[0034] In order to improve the stability of the vehicle body when adjusting the size, such as Figure 1 and Figure 4 As shown, in this embodiment, the first mounting frame 21 has grooves on both sides of its upper end surface, into which limit frames 212 are embedded. The tops of the two limit frames 212 are welded to the bottom of the first frame 11, and a slide bar 2121 is fixedly mounted within each limit frame 212. The design of the first mounting frame 21 with grooves on both sides of its upper end surface, into which the limit frames 212 are embedded, provides a stable mounting position for the slide bar 2121. The tops of the limit frames 212 are welded to the bottom of the first frame 11, ensuring structural stability. The fixed installation of the slide bar 2121 increases the strength and durability of the adjustment mechanism 2, enabling it to withstand heavier loads.

[0035] Furthermore, the second mounting frame 22 has slots on both sides of its upper end surface, into which movable frames 222 are embedded. The tops of the two movable frames 222 are welded to the bottom of the second frame 12, and the two slide bars 2121 pass through the two movable frames 222. In this design, the second mounting frame 22 has slots on both sides of its upper end surface, into which the movable frames 222 are embedded. This design allows the slide bars 2121 to slide freely within the movable frames 222, thereby adjusting the length of the vehicle body 1. The tops of the movable frames 222 are welded to the bottom of the second frame 12, providing a stable sliding platform and smoothing the movement of the slide bars 2121.

[0036] Furthermore, both slide rods 2121 are parallel to the screw rod 23 and do not contact the bottom of the vehicle body 1. The front ends of both slide rods 2121 pass through the movable frame 222 and are fixedly mounted with a stop block 21211. This design, in which the slide rods 2121 are parallel to the screw rod 23 and do not contact the bottom of the vehicle body 1, reduces friction during sliding and improves the efficiency of the adjustment mechanism 2. The front ends of the slide rods 2121 pass through the movable frame 222 and are fixedly mounted with a stop block 21211. This design ensures the stability of the slide rods 2121 during adjustment and prevents them from deflecting under heavy loads.

[0037] Furthermore, a grip 2311 is rotatably mounted on the end of the handwheel 231 facing away from the screw 23. This design provides a more user-friendly grip. The grip 2311 reduces operator effort when turning the handwheel 231, especially when making fine adjustments or requiring high torque. The grip 2311 provides an additional grip point, making operation more comfortable and accurate.

[0038] When the present invention is in use, ensure that the loader is in a stable state, there are no obstacles around, and the materials to be loaded are ready, rotate the handwheel 231 to drive the adjusting screw 23 to rotate, rotate the handwheel 231 clockwise, and the screw 23 will pull the second frame 12, thereby reducing the distance between the first frame 11 and the second frame 12, and rotate the handwheel 231 counterclockwise, and the screw 23 will push the second frame 12 to move, thereby increasing the distance between the first frame 11 and the second frame 12. After adjusting to the desired position, check whether all adjustment mechanisms 2 are firmly fixed to ensure that the adjusted size of the vehicle body 1 is suitable for loading the predetermined materials, and can be tested after loading a small amount of materials to ensure the stability of the loader and the reliability of the adjustment mechanism 2. After confirming that the size adjustment is completed, the construction materials can be placed on the loader. After loading the materials, perform a final safety check to ensure that all materials are safely placed on the loader, do not exceed the edge of the loader, and will not slip during transportation. Use the push frame 111 and wheels 122 to push or pull the loader.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
