MOBILE GOLD MINING COMPLEX Russian patent published in 2022 - IPC B03B7/00 E21C41/30 E21C47/10 

FIELD: mining industry.

SUBSTANCE: invention relates to the mining industry, in particular to devices for the extraction and enrichment of alluvial gold. Mobile gold mining complex contains mounted on two caterpillar carts and pivotally connected mechanism for supplying sands and their disintegration in the form of an excavator installation installed on the first caterpillar cart, and a mechanism for screening and jigging the heavy fraction, its accumulation for subsequent extraction for the purpose of finishing, made in the form of a scrubber -butary, connected to the dump conveyor and installed on the frame of the second caterpillar bogie, made with the possibility of adjusting the lifting angle of the scrubber-butary by means of hydraulic cylinders. The excavator installation contains a body, a receiving table located in the lower front part of the body, a working body for supplying sands mounted on the body above the receiving table and made of a rotary type, with a rotation angle of 180°, for capturing and moving sands to the one installed on the said body with the possibility lifting by means of a lifting hydraulic cylinder to a chevron belt conveyor for further supply of sands to the receiving hopper of the scrubber-butary, a cabin for accommodating two operators and one technical worker, in which the monitoring and control system of the mentioned mechanisms is located, and a diesel oil station. On the frame of the second caterpillar truck, a vibrating sieve with a receiver for separation into two fractions is installed on inflatable wheels. In the tail part of the scrubber-butares, flat square-shaped perforated sieves with cut holes in the shape of a trapezoid and located at an angle of 45° relative to the horizontal axis of the scrubber-butares are installed in series in two rows. The receiving table, the receiving hopper and the vibrating sieve, having main heat exchange cavities, are made with the possibility of heating from a diesel oil station using a double-circuit heat exchange system.

EFFECT: reduction of useful product losses during placer gold mining.
