GRAIN STORAGE SILO Russian patent published in 2025 - IPC E04H7/30 A01F25/16 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to silos intended for long-term storage of grain. Task is to create a reliable, strong and simple structure of a grain storage silo. Grain storage silo comprises a cylindrical frame made of corrugated sheets, reinforced by vertical posts arranged along the perimeter, a conical roof with a rafter system resting on the frame. Frame is a multi-tier structure, where each tier is formed by a horizontal row of corrugated sheets fixed in a ring, and the first tier of the frame corresponds to the row on which the rafter system of the conical roof of the silo rests. Vertical post is a row of base stringers 8, where on first base stringer 8 the rafter system of the conical roof of the silo rests, and starting from the second tier, the thickness of the frame increases provided that on the fifth, ninth, thirteenth, sixteenth tier, the thickness of the corrugated sheets is increased compared to the previous tier, and the remaining tiers are made of the same thickness compared to the previous tier, or provided that on the fifth, ninth, thirteenth, seventeenth, twentieth tier of the frame, the thickness of the corrugated sheets is increased compared to the previous tier, and the remaining tiers are made of the same thickness compared to the previous tier; thickness of fourth, sixth base stringer 8 is made increased compared to previous base stringer 8, and remaining base stringers 8 are made of the same thickness compared to previous base stringer 8, on last basic stringers 8, the vertical post contains embedded insert stringer 10 or a row of insert stringers, other basic stringers 8 are connected to each other by means of connecting elements. Vertical post on last basic stringer 8 contains support 13 consisting of a vertical part and a transverse plate. Basic stringer 8, insert stringer 10, the connecting element and the vertical part of the support have the same profile.

EFFECT: optimization of metal consumption of silo carcass.
