Portable powered sifter

A portable, powered sifter comprising:

• a sifter frame defining a frame opening and comprising:
• a first U-shaped sub-frame;
• and
• a second U-shaped sub-frame, the second U-shaped sub-frame slidably engaging the first U-shaped sub-frame for adjusting a size of the frame opening;
• wherein the first U-shaped sub-frame and the second U-shaped sub-frame define 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 the frame opening;
• a wire mesh extending across the frame opening;
• a support leg attached to and extending from the middle portion of at least three of the plurality of side members;
• a means for driveshaft rotation attached to the sifter frame;
• a driveshaft extending along a longitudinal axis and coupled to the means for driveshaft rotation;
• and
• an offset weight connected to the driveshaft;
• wherein 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;
• and
• wherein the portable, powered sifter is sized and constructed to be portable by a single individual capable of lifting 75 pounds.

In combination, a wheelbarrow and a portable, powered sifter comprising:

• a wheelbarrow comprising:
• a wheelbarrow frame including a first handle and a second handle and at least two leg supports;
• a wheelbarrow tray mounted on the wheelbarrow frame and having a bottom, a perimeter rim, a first side wall portion, a second side wall portion opposite the first side wall portion, a rear side wall portion, and a front wall portion opposite the rear side wall portion;
• and
• one or more wheels connected to the wheelbarrow frame;
• wherein the wheelbarrow is configured to be supported on the ground by the at least two leg supports and the one or more wheels;
• and
• a portable, powered sifter sized to be removably supported by the wheelbarrow tray and comprising:
• 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 extending across the frame opening;
• a support leg attached to and extending from the middle portion of at least three of the plurality of side members;
• a means for driveshaft rotation attached to the sifter frame;
• a driveshaft extending along a longitudinal axis and coupled to the means for driveshaft rotation;
• and
• an offset weight connected to the driveshaft;
• wherein 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;
• and
• wherein the portable, powered sifter is sized and constructed to be portable by a single individual.
