Abstract
A soil sifter, e.g. a soil sifting device, has a body (figure 1) which is an inclined mesh
drum (A), with open end upper most which is loaded with garden material to be
sifted. The bottom of the drum is closed except for a helical labyrinth (figure 2).
On rotating the drum in one direction the material is agitated and separated
through the mesh rolling up and over the step shown in the helical back plate (B)
(figure 4). Sifted soil then falls to a barrow or container below the drum (A). Larger
debris is expelled from the bottom of (A) when the rotation is reversed. Debris
falls through the labyrinth formed by the helical back plate (B)(figure 1,2,3,4).
The inclined drum (A) is supported by a portable frame (D), to which is attached the
motor housing or crank handle (C).
