Abstract
A dirt sifting device for placement over a wheelbarrow, comprising a frame and a filter screen disposed over the frame. In an embodiment of the present invention, the dirt sifting device comprises a first frame connected by a hinge to a second frame. The hinge allows the first frame to rotate relative to the second frame and is adapted to maintain the frames at any of a variety of angles. A filter screen is disposed over each of the first and second frames. The frames define the perimeter of the filter screens. The frames may be rotated towards one another such that the frames overlap in a closed configuration convenient for storage. Alternatively, the frames may be rotated away from one another and the device can then be placed over a wheelbarrow for dirt sifting. Overall, the device serves as a means for separating dirt from unwanted materials.
