Description

Technical Field

[0001] This utility model belongs to the field of coal mine conveying technology, and in particular relates to a wear-resistant and impact-resistant curved coal chuting pipe liner structure. Background Technology

[0002] Curved coal chutes are key components in coal conveying systems (such as belt conveyor transfer, storage, loading and unloading, etc.) that connect different equipment and guide coal flow. Their curved design has unique advantages over traditional straight coal chutes.

[0003] Curved coal chutes extend the coal's descent time through an arc-shaped path, gradually consuming kinetic energy by utilizing the guiding effect of the pipe's inner wall, thus reducing the impact on downstream equipment. However, when coal blocks are transported into the inner cavity of the curved coal chutes, the coal blocks in a high-speed transmission state exert a strong impact force on the stationary liner. To address this, a wear-resistant and impact-resistant curved coal chutes liner structure was designed. This structure uses a rotatable movable liner, combined with an auxiliary support structure. By employing the damper principle, the impact force exerted by the coal blocks on the movable liner is absorbed and consumed by the auxiliary support structure, thereby extending the service life of the liner. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant and impact-resistant curved coal chute liner structure, which allows the impact force exerted by coal blocks on the movable liner to be absorbed and consumed by the auxiliary support structure, thereby extending the service life of the liner and solving the aforementioned technical problems.

[0006] Preferably, the auxiliary support structure includes two first fixed corners welded to the rear side of the movable liner, and two second fixed corners welded to the right side of the inner cavity of the curved coal drop pipe.

[0007] Preferably, the surfaces of the first fixed angle and the second fixed angle are rotatably connected to adapters, and hollow round tubes are welded to the opposite sides of the two adapters.
