[0036] The second concave rod 6 has a positioning function for the front end of the first dustproof cloth 3. After the sliding end of the first dustproof cloth 3 slides toward the rear side of the vehicle, it ensures that the first dustproof cloth 3 can be unfolded and covered on the dump truck compartment.

[0037] The first concave rod 5 on the rear side of any of the above-mentioned guide rails 2 is connected to a traction mechanism that drives it to slide.

[0038] In the utility model, after the dump truck cargo compartment 1 is loaded with materials, the traction mechanism drives the first concave rod 5 connected thereto to move toward the rear side of the vehicle, and multiple first concave rods 5 are distributed at intervals on the guide slide rail 2, so that the first dustproof cloth 3 connected by the multiple first concave rods 5 forms a cover for the dump truck cargo compartment 1, preventing the dust of the materials from floating away, and protecting the environment.

[0039] When the traction mechanism drives the first concave rods 5 connected thereto to move toward the front side of the vehicle, the plurality of first concave rods 5 all slide to the front side of the guide rail 2 , thereby folding and storing the first dustproof cloth 3 .

[0040] In some embodiments of the utility model, the traction mechanism includes an annular traction rope 15 connected to the first concave rod 5, a fixed pulley 18 is rotatably provided on the inner annular surface of one end of the annular traction rope 15, and a driving structure is provided on the other end of the annular traction rope 15.

[0046] In the above embodiment, the upper side of the guide rail 2 has a slide groove, the pulley 14 and the slide groove are slidably matched, and the slide groove 16 penetrates into the slide groove. Under the pulling action of the annular traction rope 15, the transmission shaft 17 slides in the slide groove 16, thereby driving the pulley 14 to move in the slide groove.

[0047] The sliding fit between the pulley 14 and the guide rail 2 has the advantage of low friction.

[0048] In some embodiments of the present invention, the two first concave rods 5 on the rear side of the two guide rails 2 are commonly connected to a concave adjustment rod 11, and any vertical portion of the concave adjustment rod 11 is rotationally connected to the first concave rod 5 through a torsion spring, and the torsion spring rotates the concave adjustment rod 11 toward the front side of the dump truck cargo compartment 1;

[0049] A second dustproof cloth 4 is arranged between the concave adjustment rod 11 and the first dustproof cloth 3;

[0050] Limiting posts 10 are provided on both sides of the rear portion of the cargo compartment 1 of the dump truck, and the limiting posts 10 are used to abut and cooperate with the lower portion of the concave adjusting rod 11 .

[0051] In the above embodiment, the vertical portion of the concave adjustment rod 11 is rotatably connected to the first concave rod 5, and the vertical portion of the concave adjustment rod 11 is located outside the first concave rod 5; when the first concave rod 5 drives and the lower portion of the concave adjustment rod 11 abuts against the limit column 10, the concave adjustment rod 11 flips toward the rear side of the vehicle, so that the second dustproof cloth 4 covers the opening at the rear end of the first dustproof cloth 3.
