Coal bin dredging device

Abstract

The invention discloses a coal bin dredging device. The device is used for dredging a coal bin, is arranged on the lower part of the coal bin, and comprises a water spray gun freely extending into the coal bin and a power device which is connected with the water spray gun to drive the water spray gun to move freely in the coal bin. The coal bin is dredged by using the water spray gun; blocked coal in the coal bin is cut by using a water column sprayed out by the gun; the spray angle of the gun in the coal bin can be randomly adjusted to swing the sprayed water column back and forth and left and right to cut the piled coal from multiple angles and multiple surfaces, so a coal shed structure can be efficiently damaged, the coal is smoothly crushed into small pieces, and the cut coal passes through a narrow part of the coal bin smoothly; water is used as a medium for cutting and breaking the coal and can be conveniently obtained in actual working environments, water cutting is safe and other factors which cause dangerous conditions in the coal bin are not introduced, and dangerous direct operation is not required to be performed manually in the cutting process, so the safety of coal bin dredging is greatly improved.

Description

technical field [0001] The invention relates to the technical field of coal machinery equipment, and more specifically, relates to a coal bunker dredging device. Background technique [0002] Coal bunker refers to the container for placing the required coal materials in the production work, and it is also used for the transportation of coal materials. It has certain stability and also has a certain coal storage buffer function. It is often in the connection point connecting the upper and lower coal transportation processes, which directly affects the continuous production of coal. [0003] In common production situations, due to the limited diameter of the coal bunker, its long height and narrow outlet, the passage of coal will be restricted to a certain extent, which causes the coal to be trapped in the coal bunker under the action of its own weight. A natural arch is formed, resulting in shed coal, that is, coal with high humidity. During the transportation process, agglo...
