SELF-PROPELLED LOADING MACHINES FOR MINING OPERATIONS Russian patent published in 2007 - IPC E21F13/00 E21D9/12 

FIELD: mining industry, possible use for mechanization of operations in underground mines, in particular for cleaning ore fines and backfill material out of inter-rail space and side zones of railways, and also for other cleaning operations at haulage ways.

SUBSTANCE: self-propelled loading machine for mining operations contains bearing frame with rail type propulsion devices, and following devices, held on the frame: operator booth, transporter with loader, equipped with toothed bucket, interacting with rods of hydro-cylinders of its engine. Transporter in loading zone is positioned asymmetrically relatively to longitudinal axis of the machine, while operator booth is displaced in opposite direction relatively to transporter. Bearing frame is provided with bent frame capable of rotation in horizontal plane, fastened to which are bodies of hydro-cylinders of loader bucket, and bucket is provided with beams, one support of which is connected to body of corresponding hydro-cylinder, and another support - to its rod. Bucket is additionally equipped with traction bars, which are jointly connected to bucket by one end, and by other end are connected to rotary bent frame, while bottom of bucket is made with side shelves of angled shape, while unloading zone of bucket is provided with lengthening piece, and transporter is equipped with collapsible inclined drops, projecting beyond its dimensions in horizontal plane. Operation booth is located in zone of connection with inclined collapsible drops.

EFFECT: increased compactness, maneuverability and universality of machine, improved quality of cleaning of inter-rail and rail-adjacent space.
