Abstract
A shaker assembly for use on chain conveyors on harvesters is bolted to the side frame of the conveyors. The shaker assembly includes two spaced roller assemblies which carry rods of the chain conveyor. The distance between the roller assemblies may be varied such that the degree of shaking imparted to the rods as they pass over the shaker assembly may be adjusted.
Claims5
A shaker assembly for use on driven endless rod chain conveyors of the type having a plurality of substantially parallel, spaced rod members on which root crops may be conveyed, said shaker assembly comprising:
- (a) a body securable to a frame of a chain conveyor, said body including a first opening and a second opening spaced from said first opening;
- (b) means for securing said body to a frame of a chain conveyor;
- (c) a first roller assembly mounted to said body through said first opening;
- and
- (d) a second roller assembly mounted to said body through said second opening;
- said second roller assembly being spaced from the first roller assembly by the spacing between said first and second openings, at least one of said openings being elongated in a direction toward the other opening such that the distance between said roller assemblies may be adjusted by moving a roller assembly along the elongated opening.
In a harvester for root crops comprising a driven endless chain conveyor comprising a plurality of substantially parallel, spaced rod members on which root crops may be conveyed said rods being linked together by hooks or belts, said conveyor further including a frame extending between drive and roller assemblies which support said belts or hooks, the improvement comprising:
- shaker assembly means securable to said conveyor frame for imparting a wave-like vibration to said rods;
- said shaker assembly means including a body securable to said frame, said body including a first elongated openings and a second opening spaced from said first opening,
- a first roller assembly secured to said body through said first opening;
- and
- a second roller assembly secured to said body through said second opening and being spaced from said first roller by the spacing between said first and second openings, said shaker assembly means body being securable to said conveyor frame such that said rod members may contact the outer surfaces of said first and second rollers, wherein said first opening is a slot elongated in the direction toward said second opening such that said first roller assembly may be moved toward or away from said second roller assembly, said roller spacing being adjustable by moving said first roller assembly within said first opening toward or away from said second roller assembly, said roller assemblies having a diameter relative to the spacing of rods in the conveyor such that the angle between a first rod, roller assembly and second rod when said first and second rods contact said roller assembly is between about 85 and about 110 degrees.
