FIELD: agriculture. SUBSTANCE: grain storage has grain charging, grain discharge and grain storage devices including electrovacuum pump with branch pipe and adsorber mounted on branch pipe. Grain charging device has vacuum hood mounted on spring suspensions and provided with air-tight sealing members and latches, and spherical transfer vacuum spout communicated with hood through corrugated vacuum pipeline. Pipeline corrugations are formed by coiling and fastening cord to pipeline. Absorber is made from air-permeable tight fabric. Dust catcher is mounted on branch pipe of electrovacuum pump. EFFECT: increased efficiency by improved grain discharge equipment and prolonged storage time. 4 dwg
