Embodiment Construction

[0014] Embodiment 1 of the present invention, such as Figure 1-3 Shown: the anti-running coal device of the belt conveyor, including the door frame support 1, the coal retaining plate 2 for blocking coal blocks is suspended on the door frame support 1, and the door frame support 1 and the coal retaining plate 2 are connected together by a chain 3 , the coal retaining plate 2 has an inner concave arc surface 4 for reducing the speed of the coal block with an opening facing the coal block, a buffer layer is fixed on the inner concave arc surface 4, and the buffer layer includes an adhesive tape strip 5 extending in the up and down direction, The adhesive tape strips 5 are evenly distributed along the circumference of the concave arc surface, the height of the lowermost end of the adhesive tape strips 5 is lower than that of the coal retaining plate, and the lower part of the buffer layer is an arched structure.

[0015] Except for the above-mentioned embodiment 1, other embodim...

Abstract

The invention relates to the technical field of coal mine equipment, particularly to a coal leakage preventive device of a belt conveyor. The coal leakage preventive device comprises a coal stop board arranged above a belt and used for stopping coal briquettes, and the coal stop board is provided with a concave camber surface with the opening facing the direction of the coal briquettes and used for reducing the speed of the coal briquettes. Compared with the prior art, the opening of the concave camber surface of the coal stop board faces the direction of the coal briquettes, when the coal briquettes bump against the concave camber surface, not only speeds of the coal briquettes are reduced, but also stressed areas of the coal briquettes are reduced, the possibility that the coal briquettes are crashed is reduced, and therefore the lump coal rate of the coal briquettes can be improved.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a coal running prevention device for a belt conveyor. Background technique [0002] In the coal flow system of the coal mine, especially at the coal drop point of the coal flow system of the inclined roadway, due to the drop in the coal flow system at the reloading point, after the coal falls into the lower coal flow system, it will slide down the inclined roadway or even go down When the roadway quickly rolls down to the outside of the belt, the phenomenon of coal running occurs. The phenomenon of coal running is more harmful in the coal flow system. If the coal block is larger and the rolling speed is faster, it will threaten the safety of people and equipment in the roadway, endanger personal safety and damage equipment. In order to ensure the safety of people and equipment in the inclined coal flow system, anti-running coal devices are usually used to prevent the...
