Vertically retractable transfer machine head baffle

Abstract

This utility model relates to the technical field of scraper conveyors in coal mine underground fully mechanized mining faces, specifically a vertically retractable conveyor head baffle. This utility model designs the conveyor head baffle as two parts: a fixed frame and a movable frame. The fixed frame is bolted to the head frame on its side. The movable frame is connected to the fixed frame at both ends by a hydraulic cylinder, and fixing pin holes are provided on both the fixed and movable frames. The movable frame is equipped with guide blocks that allow it to slide within the fixed frame's slide rail. The movable frame's extension and retraction are controlled by the hydraulic cylinder. When it reaches the appropriate position, a positioning pin is inserted to position and connect the fixed and movable frames. This solves the problem of interference and belt tearing between the conveyor head baffle and the conveyor belt at the tail end caused by changes in the slope of the roadway. This utility model has a simple design principle, is easy to implement, and has good economic adaptability.
