SAMPLER WORKING UNIT LIFTING AND FORCED SINKING MECHANISM Russian patent published in 1994 - IPC

FIELD: mining. SUBSTANCE: during winch 3 drum counter clockwise rotation rope branch 5 is being uncoiled and sampler 6 is going down. Simultaneous the other rope branch 8 of the drum is coiling up round the drum of the winch 3 and pulls down sampler 6. During this process working unit of sampler 6 is sinking into stuff under action of weight of sampler 6 and pulling strength of rope branch 8. During winch 6 drum clockwise rotation rope branch 5 is being coiled up round the drum of winch 3 and rope branch 8 is being uncoiled from the drum. A system of blocks 2 and 9 orientates position of branches 5 and 8 in space accordingly. EFFECT: mechanism is effective in mechanized sampling of loose stuff. 2 cl, 2 dwg
