Description

Technical Field

[0001] The utility model relates to the field of mining equipment, in particular to an intelligent floating coal cleaner for a coal mining working face. Background Art

[0002] With the implementation of mechanized replacement of workers and intelligent reduction of manpower in coal mines, more and more intelligent coal mining faces are being built in coal mines. The memory cutting production of intelligent coal mining faces encounters floating coal on the working face that is difficult to clean, resulting in coal accumulation in front of the hydraulic support of the working face and old coal left in the old mountain. Manual intervention is required to operate and clean up the floating coal, which increases the labor intensity of employees and reduces the production efficiency of the coal mining face.

[0003] The utility model patent with application number CN202321006537.X discloses a floating coal cleaning device for an ultra-thin coal seam coal mining machine, including a collecting mechanism and a coal cleaning mechanism. The collecting mechanism includes a rocker arm and a coal mining machine drum. A coal cleaning mechanism is hung on the rocker arm. The coal cleaning mechanism includes a bucket and a lifting assembly. The upper end of the lifting assembly is connected to the rocker arm, and the lower end of the lifting assembly is connected to the bucket. When the collecting mechanism rotates, the lifting assembly can keep the vertical height of the bucket constant. When the rocker arm controls the coal mining machine drum to swing up and down, the lifting assembly can adaptively extend and retract according to the moving state of the rocker arm, thereby keeping the bucket always on the coal mining machine path, and the floating coal removal effect is good.

[0004] However, the bucket of the above floating coal cleaning device can only remove floating coal as the coal mining machine moves, and the bucket cannot remove floating coal autonomously when the coal mining machine stops moving. The flexibility of the bucket is poor, and the floating coal removal effect is relatively general, which needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide an intelligent floating coal cleaner for a coal mining working face, wherein a scraper can remove floating coal more flexibly, so as to solve the defects mentioned in the above-mentioned background technology.
