DETAILED DESCRIPTION

[0026] The technical scheme of the utility model will be described below in connection with the embodiments, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0027] Referring to Figure 1-Figure 5 , the utility model provides a technical scheme:

[0028] As Figure 1-Figure 5 shown, a road surface gravel scattering device, including material box 1, base 2, scattering box 3 and adjusting assembly 4, the material box 1 is fixed on the base 2, the adjusting assembly 4 is located on the side of the base 2 close to the tail, two scattering box 3 about the center symmetry arrangement of adjusting assembly 4, the top of scattering box 3 with the base 2 between being equipped with guide rail 31 and sliding block 32, the adjusting assembly 4 includes driving motor 41 and gear 42, the guide rail 31 close to the side of gear 42 is equipped with the rack 43 of cooperation, two scattering box 3 through the synchronous motion of adjusting assembly 4;

[0029] The top of scattering box 3 is communicated with the bottom plate of material box 1 through hose 6, the bottom of scattering box 3 is hollow mesh structure, and the bottom of scattering box 3 is provided with shielding assembly 5.

[0030] Through the above technical scheme, the gravel, stone chips and the like are loaded into the material box 1, are supplied into the cuboid-shaped scattering box 3 through the hose 6, and the two groups of scattering boxes 3 can be driven to move towards each other or opposite by the adjusting assembly 4, and then the corresponding adjustment can be carried out according to the width of the required scattering.

[0031] Since the bottom of the scattering box 3 is a hollow mesh structure, the gravel falls from the mesh and completes the scattering as the whole scattering device moves. The leaked mesh can be shielded by the shielding assembly 5, and then the area of scattering is adjusted, so when the two scattering boxes 3 are opened to the two sides, if there is an overlapping part in the middle, the middle overlapping part of one of the scattering boxes 3 can be blocked by the shielding assembly 5 to avoid uneven scattering.

[0032] At the same time, when the adjusting assembly 4 is not started, the spreading areas of the two spreading boxes 3 overlap, and the two spreading boxes 3 can spread simultaneously to spread double-layer sand gravel, which is suitable for the case where a relatively thick layer needs to be spread.

[0033] At the same time, when the adjusting assembly 4 is started, the two spreading boxes 3 move to the two sides, can spread to the two sides of the base 2, and can effectively spread the road edge to ensure the spreading effect of the road.

[0034] Further, the motor base of the driving motor 41 is fixed on the top of the base 2, the motor shaft of the driving motor 41 penetrates through the base 2 and is connected with the gear 42. The length of the rack 43 is matched with the length of the spreading box 3, and the length of the guide rail 31 is longer than the length of the spreading box 3.

Since the rack 43 is fixed on one side of the sliding block 32 and is engaged with the gear 42, when the driving motor 41 drives the gear 42 to rotate, the gear 42 drives the engaged rack 43 to move, and then drives the two spreading boxes 3 on the two sides to move synchronously.

[0036] Further, the connection between the guide rail 31 and the sliding block 32 is in a dovetail structure.

[0037] Through the above technical scheme, the sliding block 32 and the guide rail 31 are in a dovetail structure, so that the sliding block 32 cannot fall off the guide rail 31 in the vertical direction, and the spreading box 3 is supported.

[0038] Further, the base 2 is provided with a slot 21 at a position corresponding to the hose 6 connection port of the spreading box 3, the direction of the slot 21 is consistent with the moving direction of the spreading box 3, and the hose 6 penetrates through the slot 21 and is connected with the spreading box 3.

[0039] Through the above technical scheme, the spreading box 3 is connected with the material box 1 through the hose 6. Since the spreading box 3 moves back and forth during work, the hose 6 is avoided from being interfered. The slot 21 is arranged on the base 2 to facilitate the movement of the hose 6 along with the spreading box 3. Meanwhile, a fan can be arranged at the bottom of the material box 1 to blow the material in the material box 1 into the spreading box 3 through the hose 6, so that there is enough sand gravel in the spreading box 3, and the sand gravel is evenly spread.
