ABSTRACT:
The invention provides a drum shaker apparatus for use in seed or vine crop harvesters with improved effectiveness in removing seeds or fruit from the plant portion of the crop. The drum shaker includes a rotatable drum to which is mounted a counterweight mechanism having at least three rotatable counterweights, each counterweight having an axis of rotation spaced apart from its center of mass, and means for rotating the counterweights in a phased relationship. Usually, the drum is rotated at a constant angular speed, onto which is superimposed the oscillatory movement caused by rotation of the counterweights. The drum shaker further includes tines extending outward from its surface for engaging the crop. The present invention provides tines of varied stiffness arranged on the drum so as to create relative movement of adjacent tines, which tends to shear the seeds or fruit from the plants. The drum shaker of the present invention offers greater harvesting efficiency, compact size, reduced maintenance and longer life than known shaker-type harvesters.
