Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine transportation, and particularly relates to an anti-blocking curved coal drop pipe structure. Background Art

[0002] Coal mine transportation mainly involves the main coal flow transportation system of coal mines, among which belt conveyors are key transportation equipment, which are responsible for realizing continuous transportation of coal mines. In coal mine production, coal drop pipes, as key components in the coal mine transportation system, often have blockage problems at the bends of the pipes, which not only affects production efficiency, but also increases equipment maintenance costs and safety risks.

[0003] According to the utility model with authorization announcement number CN213737341U, a blocking-proof curved coal dropping structure is disclosed, including a guide hood and a roller connected to the top open end of the guide hood, an upper conveyor belt is wrapped around the outer diameter of the roller, and the conveying direction of the upper conveyor belt is toward the inner cavity of the guide hood, and a guide hood baffle is provided in the inner cavity of the guide hood. The guide hood baffle is an arc-shaped structure, one end of the guide hood baffle is connected to the top surface of the guide hood, the other end of the guide hood baffle is connected to the bottom open end of the guide hood and the other end of the guide hood baffle is perpendicular to the lower conveyor belt, and the bottom open end of the guide hood baffle is also connected to a curved coal dropping pipe.

[0004] While the above technical solution reduces impact and increases the contact area between the coal flow and the pipe wall, converting the sudden kinetic energy loss caused by impact into a slow kinetic energy loss due to friction, thus reducing the dust generated by impact and the adhesion of wet coal to the pipe wall caused by impact, the above technical solution fails to effectively remove the dust adhering to the pipe wall during use, and a large amount of dust still adheres to the inner wall of the pipe during use.
