MINING MACHINE FOR TRANSPORTATION OF STEMMING MATERIAL AND MECHANIZED STEMMING OF BLAST HOLES Russian patent published in 2024 - IPC B60P1/36 F42D1/12 

FIELD: mining transport equipment.

SUBSTANCE: truck for transportation of bottom-hole material and its supply to blasting wells contains a body, a transport-loading bin for bottom-hole material and a delivery system for supply of bottom-hole material from the hopper to the blast hole. Above delivery system includes a hopper conveyor and a folding conveyor turning relative to the body, supplying the bottom-hole material to the blast hole. Said hopper and folding rotary conveyors interact directly with each other and have a scraper-type structure. Hopper conveyor is a feeding conveyor, located in the bottom part of the transport-loading hopper and is made with possibility of movement of the stemming material, moving forward, by means of the sliding means equipped with scrapers, to the folding and unloading rotary conveyor, which has a folding structural stand, turns relative to its axis, and is also installed in the working position on the support-rotary device for the possibility of directing the bottomhole material into the blast hole.

EFFECT: high reliability of transportation, as well as high accuracy and speed of stemming of vertical and inclined blast holes at open development of minerals.
