A double bank cleaner for granular material includes two spaced banks of cleaning decks mounted in a frame with a drive motor and rotatable eccentric positioned between the two banks so that the banks of decks can be gyrated in a flat, horizontal plane. An aspirator for the double bank cleaner is also disclosed, and which comprises a plurality of feeders each of which creates a curtain of granular material through which air is passed to remove dust and the like.

A double bank cleaning device for granular and like material comprising: an outer, open frame of rectangular configuration having spaced end frames interconnected by upper and lower cross beams; an inner frame suspended from said outer frame by universal joints thereby to allow said inner frame to move in a horizontal plane relative to said outer frame; two spaced banks of cleaning decks mounted in and secured to said inner frame, said decks having infeed ends and outlet ends extending beyond the confines of the outer frame and adapted to convey granular material throughout their length; and drive means mounted on said inner frame between said spaced banks of cleaning decks, said drive means comprising a box enclosure secured to the inner frame, a dead shaft vertically mounted in said box enclosure, an eccentric weight mounted for rotation in a horizontal plane on said dead shaft and motor means for rotating said weight thereby to impart a flat, rotary motion to said suspended inner frame and the double bank of cleaning decks secured therein; and including a multi-feed aspirator for feeding granular material into said cleaning device, said aspirator comprising a housing mounted above said outer frame; a plurality of horizontally disposed feed rolls mounted in said housing, one above and forward of the other, each roll feeding a curtain of granular material, by gravity, down through the housing and into said infeed ends of said decks, and a plurality of ducts directing air generally horizontally against said curtains of granular material to carry lighter-than-grain pieces into a drop out section. An aspirator for mounting on top of a grain cleaning machine comprising: a housing having an intake section and an exhaust section, said housing being adapted for connection to fan means for passing air through said housing from the intake to the exhaust sections; said intake section having an inlet in its upper end for receiving granular material therein, and an outlet in its lower end for dropping granular material into cleaning decks of said cleaning machine; baffle means dividing said intake section between its granular inlet and outlet and extending generally diagonally across said intake section; means in said baffle means for metering granular material therethrough in a plurality of downwardly flowing curtains extending across said intake section; and means for directing the air passing through the housing to impinge upon said downwardly flowing curtains thereby to carry material lighter than said granular material out of said intake section and into said exhaust section; said baffle means comprising a stepped panel extending generally diagonally from one end wall of the intake section to the top wall thereof, said stepped panel having a series of vertical sections separated by horizontal sections, said metering means being located in the horizontal sections and the air directing means being located in the vertical sections; said metering means comprises a plurality of feed rolls extending across said baffle means, each feed roll being located adjacent to and below said vertical and horizontal sections, and gate members in the horizontal sections in contact with the feed rolls for passing granular material through the baffle means, and drive means for rotating said feed rolls.
