AI Technical Summary

Technical Problem

Scraper conveyors generate a large amount of dust when conveying dry, fragile raw coal. The dust adheres to the surface of the partitions and chain plates, causing it to accumulate inside the equipment and affecting its continuous operation efficiency and service life.

Method used

The system employs an air jet cleaning assembly and a guiding collection structure. The air jets blow air onto the conveyor belt and partitions to clean away residues, while the guiding collection structure directs the residues to a predetermined area. Combined with a lubrication assembly and a dust suppression assembly, it achieves automated cleaning and dust suppression.

Benefits of technology

It effectively prevents dust from accumulating inside the equipment, improves cleaning efficiency, reduces wear, extends equipment lifespan, and ensures the continuity and stability of material conveying.

Abstract

This invention relates to the field of scraper conveyor technology in coal mines, and discloses a scraper conveyor including a fixed base with an internal accommodating space; a transmission mechanism disposed in the accommodating space, including a transmission wheel set, a conveyor belt driven by the transmission wheel set, and multiple partitions spaced apart on the outer periphery of the conveyor belt; an air jet cleaning assembly including an air source, an air jet plate with an air jet nozzle, and an air supply pipe connecting the air jet plate and the air source; the air jet plate is disposed in the accommodating space, with at least one air jet plate respectively disposed on opposite sides of the conveyor belt along its width direction, the air jet nozzle facing the conveyor belt, for blowing air onto the passing conveyor belt and partitions to clean residues; and a guide collection structure disposed in the accommodating space, wherein the bottom of the partitions passing the air jet plate can slide over the top of the guide collection structure, scraping off the residues on the bottom surface of the partitions, which are then guided and collected by the guide collection structure to a predetermined area.
