LOADING HOPPER FOR RECEPTION, ACCUMULATION AND TRANSFER OF ROCK MASS TO BELT CONVEYOR Russian patent published in 2025 - IPC B65G47/20 E21F13/08 

FIELD: transportation.

SUBSTANCE: loading hopper (1) for reception, accumulation and transfer of rock mass to belt conveyor is equipped with control system and is installed on running and running end rails (18), which are hinged to each other. Loading hopper (1) is rigidly connected with control hydraulic cylinder (22) for repulsion from mine walls. Loading hopper (1) is made in the form of a tank-body with a built-in scraper conveyor and is equipped with drive section (2), which includes drive drum (3) containing hydraulic motors-reducers (4) for driving traction chain (5) of the scraper conveyor in chute (6). Drive drum (3) is made with possibility of adjustment of position by hydraulic cylinders of tension. Drive section (2) includes four guides for traction chain (5) of scraper conveyor. Loading hopper (1) additionally includes receiving hopper (7) forming middle and end parts of scraper conveyor and containing tension section (8). Chute (6) is connected to drive section (2) and receiving hopper (7) (extension (10) of the frame), preferably by bolted connections to beam (13) of hopper (7), kinematically connected to gate (14) by means of hydraulic cylinder (15) lifting. Loading hopper (1) also includes lifting hydraulic cylinder (19) fixed on support (21) rigidly connected to chute (6) and movement hydraulic cylinder (20) pivotally connected to chute (6) and running rail (18). Support (21) of lifting hydraulic cylinder (19) is made with possibility of lifting rail (18) of running gear and use of running rail (18) as support point when lifting hopper (1) of loading. Loading hopper (1) additionally includes ladder (17) for self-propelled car, connected by axles with tension section (8) of receiving hopper (7).

EFFECT: improved manufacturability of the hopper.
