  • Publication number: 20160184865
    Abstract: A portable, powered sifter is sized and constructed to be portable by a single individual. The sifter includes a plurality of side members each having end portions and a middle portion between the end portions, the plurality of side members being connected together at the end portions to define a sifter frame enclosing a frame opening. A wire mesh extends across the frame opening. A support leg is attached to and extending from the middle portion of at least three of the plurality of side members. A means for driveshaft rotation is attached to the sifter frame and a driveshaft extending along a longitudinal axis is coupled to the means for driveshaft rotation. An offset weight is connected to the driveshaft, where operating the means for driveshaft rotation rotates the driveshaft about the longitudinal axis, thereby rotating the offset weight and causing the sifter frame to vibrate.
