FIELD: agriculture. ^ SUBSTANCE: apparatus of grain outlet includes a row of funnels with transverse and longitudinal walls. Under funnels there is a chute provided, having side walls and shelves. Each shelf is fixed under according shelf and is separated from its adjacent shelf for passage of grain discharged from under funnel. Between funnels and shelves there is a shifting working element, in particular chain with scrapers. On the side of grain discharge by working element from under funnels, in lower parts of their transverse walls there are shields provided - detachable or arranged with the possibility of diversion. On the sides, opposite to shields, there might be screens provided to eliminate grain addition from under funnels, and shields are arranged with the possibility to vary height of their lower edges above shelves. Invention makes it possible to improve repairability of apparatus funnels, to protect it against breakdown in case pieces of asphalt, crushed stone, bolts, nuts and similar bulk pieces get into grain, and it required - to expand limit of apparatus efficiency variation without increase of shifting working element speed control range. ^ EFFECT: improved operational indices of discharge apparatus. ^ 6 cl, 4 dwg |
