Technical Field

[0001] The utility model relates to the technical field of coal conveying equipment for thermal power generation, in particular to a coal plow for thermal power generation. Background Art

[0002] Coal conveyor plow, generally known as plow type discharger, such as the electric plow type discharger of model SZC1400, which is applicable to a belt width of 1400mm. When working, relying on the thrust of the electric push rod, the triangular "plow head" leans down to the surface of the conveyor belt to divert the coal to the coal drop hoppers on both sides.

[0003] When the above-mentioned coal plow is working, the coal on the surface of the conveyor belt is often not scraped clean, and the coal is accumulated under the plow head. The reason is that the hard plow head does not fully contact the surface of the conveyor belt or the contact is uneven. Therefore, a new coal plow for thermal power generation is proposed to solve the above problem. Utility Model Content
