Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering technology and equipment, and particularly relates to an anti-clogging asphalt mixing device. Background Art

[0002] The water-stabilized asphalt mixing plant is primarily used in various road, bridge, and tunnel construction projects. It is an essential piece of equipment for these infrastructure projects. Specifically, it provides high-quality, high-strength concrete materials for these projects, ensuring the stability and safety of roads, bridges, and tunnels. The water-stabilized asphalt mixing plant boasts broad application prospects and technological advantages. In future infrastructure construction, it will continue to play a vital role, providing high-quality, high-strength concrete materials for various projects and promoting the smooth progress of construction.

[0003] In the existing technology, the conventional water-stabilized asphalt construction mixing device directly outputs the stirred asphalt to the storage hopper after stirring. The storage hopper moves to transport the asphalt to the insulation room. During the movement of the storage hopper, the discharge port of the mixing device is closed and the asphalt accumulates at the discharge port. If it is not discharged in time, the asphalt gradually adheres to the inner wall of the discharge port and eventually blocks the discharge port.

[0004] After searching, the utility model with publication number CN220900079U provides a stirring device for an asphalt mixture mixer, which relates to the field of asphalt mixture technology, including an overall structure and a sealing structure, and the sealing structure is located at the top of the overall structure; the overall structure includes a bracket and a first frame, and a connecting piece is fixedly connected to the top center of the bracket, and a volume barrel is fixedly connected to the top center of the connecting piece, and a rotating shaft is rotatably connected to the center of the inner surface of one side of the volume barrel, and a rotating disc is rotatably connected to the center of the inner surface of the other side of the volume barrel. However, after the mixing is completed, a storage hopper is still required to cooperate with the discharge, and the asphalt that is not discharged in time is still accumulated at the discharge port under the action of gravity, which is very prone to blockage. Summary of the Invention

[0005] The purpose of the present utility model is to solve the problem in the prior art that when the asphalt mixture accumulates at the discharge port of the mixing device after mixing, the asphalt accumulation causes part of the asphalt to adhere to the inner wall of the discharge port, resulting in blockage of the discharge port; the prior art mostly adopts the method of manual timed cleaning to remove the asphalt adhered to the inner wall, which does not solve the problem of asphalt accumulation well. In order to solve the above problem, the present utility model proposes an anti-blocking asphalt mixing device.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0035] Example 2

[0036] like Figure 1-4As shown; the anti-clogging asphalt mixing device described in the present invention needs to be used in conjunction with an additional heating device and a processing device.
