Apparatus for separation of beets and stones by dry means
摘要:
An apparatus for separation of beets and stones by dry means, which comprises an endless continuously moving separation band including a conveyor run. The conveyor run runs substantially in horizontal direction and is equipped with cam-or fingerlike driver elements disposed about perpendicularly to the surface of the conveyor run and elastically bendable merely by specific heavy stones. A feeding device is disposed at one end of the separation band and two striper brushes are disposed one behind the other above the conveyor run and driven in the same direction of rotation as the separation band. The striper brushes have bristles including points of the latter, and knob points of the fingerlike driver elements have a distance from the bristle points smaller than the thickness of the beets. The feeding device comprises means for feeding intermittently the goods to be conveyed directly to one end of the separation band. The separation band and the striper brushes are obliquely inclined crosswise to the direction of movement and, the rotary axes of the brushes converge with the lower disposed edge of the conveyor run in the direction of movement of the latter and in at least one plane about parallel to the conveyor run.
