An aggregate transfer mechanism for an anti-drift chain

technical field

The invention relates to the technical field of cleaning and transferring of bulk materials accumulated on the ground of coal mine roadways, in particular, to an automatic collection and transfer equipment used for bulk materials accumulated on the ground of coal mine roadways.

Background technique

In the process of coal seam drilling and hydraulic punching, a large amount of coal chips are discharged from the drilling and accumulate on the ground of the roadway, which brings great inconvenience to the operation of drilling equipment and workers in the roadway drilling site, and seriously affects the standardization of the mine. However, the narrow roadway space cannot use loading equipment such as bucket loaders, so the coal mine has to arrange special cleaning personnel to regularly clean the coal chips accumulated in the roadway manually, and use the shovel to load the coal chips into the mine car or conveyor. , The cleaning work is labor-intensive, the working environment is harsh, and the labor cost of coal mine production is high.

SUMMARY OF THE INVENTION

Aiming at the above-mentioned problem of coal dust accumulation on roadway ground caused by coal seam drilling and slag discharge when coal enterprises prevent and control gas, the present invention provides an aggregate transfer mechanism for anti-drift chains. The mechanism is installed on the fuselage of the traveling device, which can quickly reach the cleaning operation site, and under the action of the propulsion of the traveling device, the accumulated coal chips are automatically reclaimed and transferred through the aggregate transfer mechanism, and the coal chips are removed. It is reloaded and loaded into the mine car or conveyor at the rear. During the coal transfer process, the anti-drift scraper of the anti-drift scraper chain is used to scrape, clean and transport the coal chips adhered to the bottom plate of the tank body, effectively preventing the The phenomenon of chain drift and chain drop occurs in the process of chip transfer, which ensures the normal operation of the equipment and improves the efficiency of coal chip cleaning.

The plate has a scraping effect on the coal chips adhered to the bottom of the tank. At the same time, under the resistance of the coal chips, the anti-drift scraper is pressed towards the bottom of the tank, which further enhances the adhesion of the anti-drift scraper to the bottom of the tank. The scraping, cleaning and transporting of the coal chips on the bottom plate of the tank body, and the increased tension of the anti-drift scraper chain, effectively prevents the occurrence of the floating chain phenomenon and avoids the occurrence of chain drop accidents; when the anti-drift scraper is worn, the By adjusting the position of the bolts in the long and narrow adjustment holes of the countersunk head, the anti-drift scraper is kept in contact with the bottom plate of the tank body, so as to maintain the scraping, cleaning and conveying effect of the anti-drift scraper on the bonded coal chips on the bottom plate of the tank body, and the anti-drift scraper is improved. The service life of the board improves the cleaning efficiency of the coal chips.

The invention is compact in structure and convenient to use, and the anti-drift scraper is used to scrape, clean and transport the coal chips adhered to the bottom plate of the tank body during the coal chip transfer process, so as to prevent the occurrence of the floating chain phenomenon and improve the coal chip cleaning. Work efficiency; the aggregate transfer mechanism can move flexibly in the narrow tunnel underground through the walking device, and can actively advance to realize the automatic collection, cleaning and transfer of coal chips, instead of relying on manpower to remove coal chips with shovels. The number of coal dust cleaning staff is reduced, the labor intensity of workers is reduced, the work efficiency of coal dust cleaning is improved, the labor cost of the enterprise is reduced, and the purpose of reducing personnel and improving efficiency is achieved.
