摘要： A power sieve has a generally planar and longitudinally extending frame having upstream and downstream ends and a pair of laterally spaced side members extending longitudinally between the ends, a generally planar screen spanned longitudinally within the frame, and a plurality of longitudinally spaced and substantially parallel beater beams underneath the screen and having beam ends juxtaposed with the frame side members. Respective horizontally extending leaf springs each have one end secured to the respective side member and another end secured to the respective beam end. Thus the beams can move generally vertically on the springs. Respective beater arms extending generally parallel to the screen from the beater beams have outer ends engageable with the underside of the screen. In addition, respective actuation arms extending radially from the beater beams have outer ends connected to a rigid longitudinally extending link connected in turn to a linear drive on the frame connected to the link for horizontally reciprocating the link and thereby simultaneously and synchronously pivotally oscillating the beater beams with the respective beater arms to hammer the outer ends of the beater arms against the screen. In this manner when the screen is inclined down from the one end and particulate material is loaded onto the screen at this end the particulate material migrates down along the screen to the other end with the smaller fractions falling through the screen.

摘要： A vertical set of sieves receives the particulate material from a vibrating trough conveyor above the set and is vibrated by an agitator on the machine frame. The sieves are spread apart and then tilted to dump the collected particles into respective funnels. The set can then be swung back and contracted for the the next stage. The funnels are connected to collectors which are automatically weighted.
