SKIP DUMPER Russian patent published in 2005 - IPC

FIELD: materials handling facilities.

SUBSTANCE: invention relates to skip dumpers for hoists. Proposed device contains body, skips. Front wall of skip consists of articulated trays installed one over the other. Side walls of skip are interconnected by fixed wall and bottom and in front part, by posts-braces. Trays are provided with sides carrying levers furnished with rollers on cantilever part. Bottoms of trays in middle part are connected from outside to posts-braces, the latter being secured in side walls of skip through it their both ends. In initial position, trays are installed horizontally to prevent spilling of coal from skip body. To discharge coal from skip, skip is lifted to position in which rollers run onto discharge ski-making trays turn from horizontal position to position of angle of repose of material to be unloaded. This provides twisting of post-brace made in form of torsion bar and unloading of material from skip. Skip completely unloaded, it is lowered down, rollers move off discharge ski, and trays return in initial position under action of resilient forces of posts-brace, thus preparing skip for loading.

EFFECT: increased discharge capacity of skip and possibility of starting discharge of coal from top.
