Description

Technical Field

[0001] The utility model relates to the technical field of coal mine transfer machines, in particular to a middle trough structure of a coal mine transfer machine. Background Art

[0002] Coal mine transfer machine, whose full name is scraper transfer machine for chute, is a bridge-type scraper conveyor installed in the section transport level tunnel at the exit below the working face of the mine. When it is working, one end is overlapped with the conveyor on the working face, and the other end is connected to the tail of the belt conveyor, which plays the effect of conveying materials. A middle trough is provided on the coal mine transfer machine, so that the material can be transported forward in the middle trough as the scraper moves.

[0003] There are many types of coal mine transfer machines on the market, but the middle trough is generally only used in conjunction with a scraper for conveying operations. Due to the limited height of the scraper, this type of middle trough lacks components that can crush larger materials. When larger materials enter the middle trough, it will cause idling between the scraper and the larger materials, further causing the larger materials to pass over the scraper. The scraper cannot convey the larger materials forward, affecting the conveying effect and causing inconvenience to the user. In view of this, we propose a middle trough structure for a coal mine transfer machine. Utility Model Content
