Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 This utility model provides a technical solution: a paving material device for road construction, including a material box 1, two pairs of support rods 2 at the bottom of the material box 1, a traveling wheel 3 at the bottom of the support rods 2, a feeding hopper 4 at the bottom of the material box 1, a rotating shaft 5 rotatably installed inside the feeding hopper 4, a motor 6 connected to one end of the rotating shaft 5 on the outer wall of the material box 1, a feeding assembly on the rotating shaft 5, a partition 7 inside the material box 1, a pair of slide rails 8 on both sides of the upper wall of the material box 1, a pair of sliders 9 on the pair of slide rails 8, the upper ends of the partition 7 are detachably connected to the pair of sliders 9 by snap-fit ​​assemblies, a positioning frame 10 on the side wall of the slider 9, a horizontally arranged positioning bolt 11 screwed onto the positioning frame 10, and a plurality of positioning seats 12 spaced apart on the side wall of the material box 1, with positioning holes for the positioning bolts 11 to be inserted into the positioning seats 12.

[0022] By adopting the above technical solution, the motor 6 drives the rotating shaft 5 to rotate, thereby driving the feeding component to operate, controlling the feeding speed and uniformity of the material, and the partition 7 can be adjusted or replaced as needed to meet different material feeding requirements.

[0023] In this embodiment, the buckle assembly includes a slot 13 located on the side wall of the slider 9. The side wall of the partition 7 is provided with a plug 14 that is inserted into the slot 13. The side wall of the plug 14 is provided with a sleeve 15. A limiting rod 16 is slidably provided inside the sleeve 15. One end of the limiting rod 16 is connected to the bottom of the sleeve 15 by a spring 17. The upper wall of the slider 9 is provided with a limiting seat 18. The limiting seat 18 is provided with a limiting hole through which the limiting rod 16 passes.

[0024] By adopting the above technical solution, the limiting rod 16 can be automatically inserted into the limiting hole through the action of the spring 17, so as to quickly fix the partition 7; when disassembling, simply press the limiting rod 16 to make it disengage from the limiting hole, thus realizing the quick disassembly and installation of the partition 7 and improving maintenance efficiency.

[0025] In this embodiment, the feeding assembly includes a roller 19 fixedly mounted on the rotating shaft 5. The outer wall of the roller 19 is provided with a plurality of baffles 20 along the circumferential direction. The end of the baffle 20 away from the roller 19 slides and fits against the inner cavity of the feeding hopper 4.

[0026] By adopting the above technical solution, the motor 6 drives the rotating shaft 5 to rotate, which in turn drives the drum 19 and the baffle plate 20 to rotate. During the rotation, the baffle plate 20 pushes the material out of the feeding hopper 4, thus achieving uniform feeding.

[0027] In this embodiment, the outer wall of the material box 1 is provided with a support for fixing the motor 6.

[0028] By adopting the above technical solution, the outer wall of the material box 1 is provided with a support for fixing the motor 6, so as to ensure that the motor 6 remains stable during operation.

[0029] In this embodiment, the bottom sides of the material box 1 are tilted towards the downward hopper 4.

[0030] By adopting the above technical solution, this design allows materials to flow smoothly from the hopper 1 into the discharge hopper 4, reducing the possibility of blockage.

[0031] In this embodiment, the partition 7 is further configured to have an arc-shaped groove at the center of its lower wall to prevent interference between the partition 7 and the baffle plate 20.

[0032] By adopting the above technical solution, this design ensures that the relative movement between the partition 7 and the baffle 20 is not obstructed, thus guaranteeing the normal operation of the equipment.

[0033] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0034] Example: In use, according to construction needs, the partition 7 is installed in different positions using the snap-fit ​​assembly. The partitions inside the material box 1 are adjusted, and the positioning bolts 11 are inserted into the positioning holes in the positioning seat 12 to fix the position of the partition 7, thereby adjusting the appropriate spreading width. Then, the spreading material is poured into the material box 1, the motor 6 is started, and the rotating shaft 5 is driven to rotate, which drives the roller 19 and the baffle plate 20 to rotate. The baffle plate 20 slides and fits against the inner cavity of the discharge hopper 4 to ensure that the material is discharged evenly and to avoid blockage or accumulation. At the same time, the workers push the device along the spreading path. After completing the work of one construction section, the motor 6 is turned off, all parts are cleaned, and preparations are made for the next stage of work.
