Abstract
Abstract An inclined belt is shaped on the upper run by side rollers to form a slight trough. By-products resulting from initial seed cleaning are dropped from a hopper onto the belt just above the lower end. Heavy round seeds such as rape-seeds bounce and pass over the lower end while light seeds and flat seeds and other contaminants pass over the upper or head end. The fraction that passes over the lower or tail end drops onto a further inclined belt underneath the first belt and at a slightly flatter angle and the process is repeated but giving a basic separation of heavy rape-seed over the lower end and light rape-seed and mustard seed over the upper end both of which fractions can be used commercially.

A seed reclaiming device for recovering rape seed and the like from the by-products resulting from initial seed cleaning operations comprising in combination a supporting structure, a primary endless belt, rollers mounting in said supporting structure supporting said belt for rotation, the upper run of said belt inclining upwardly at an angle from the horizontal, a feed hopper supported in said supporting structure above said upper run and towards the lower end thereof, a secondary endless belt, rollers mounted in said supporting structure for supporting said belt for rotation, the upper run of said belt underlying said primary endless belt, the lower end of said secondary endless belt being forwardly of the lower end of said primary endless belt whereby the seed fraction passing over said lower end of said primary endless belt is deposited onto the upper run of said secondary endless belt towards the lower end thereof, means to adjust the angles of inclination of said belts independently, and a source of power for driving said belts whereby the upper runs thereof move upwardly from the lower ends towards the upper ends thereof, said primary belt inclining at a greater angle from the horizontal than said secondary belt, and means along the side edges of said upper run of said belts to raise said side edges whereby said upper runs form a shallow trough, said means including a plurality of spaced roller engaging the underside edges of said upper run, and brackets supporting said rollers, said brackets being adjustable in height, said feed hopper including a discharge extending across said upper run, said discharge being spaced above said upper run whereby material is deposited from said discharge upon said upper run after a free drop from said discharge.
