LOOSE MATERIAL GRINDER AND ELECTRIC CORD FASTENER Russian patent published in 2011 - IPC B02C18/06 B02C9/00 

FIELD: process engineering.

SUBSTANCE: invention relates to loose material grinders and may be used for grinding grain and animal feed, or in household conditions. Proposed device comprises base with motor secured thereon and proved with power cord connected with motor protective housing, working chamber arranged above said base and made up of deflector and detachable screen coupled therewith and consisting of lower screen coupled with said base and lateral screen arranged above said lower screen, and grinding element arranged on motor shaft and made up of knife. Knife extreme working edge rotates above inlet opening. Deflector has opposed grooves. Lowe screen incorporates L-like brackets welded on opposite sides with their bent parts directed in opposite directions to be fixed in deflector grooves. One of said groove represents a rectangular opening accommodating the end of said-bracket bent toward the side opposite the base, while second groove represents rectangular cutout on deflector bottom side to lock second bracket. Said knife has holes arranged symmetrically, nearby knife striking edges. Power cord attachment assy in motor protective housing comprises flexible elastic sleeve with support element and tailing end. Said attachment assy is provided with metal spring made up of L-like clip and thrust arranged on tailing end lower surface. Said L-like clip has rectangular cutout on longer arm with its width matching that of tailing end grooved, while end parts of said arm are bent opposite the shorter arm. Thrust is made up of L-like plate secured inside housing right below the hole with width smaller than spring cutout width. Housing hole s rectangular to match the shape of flexible elastic sleeve tailing end passing through said hole.

EFFECT: higher efficiency and reliability of grinding, easier manufacture and servicing.
