Definitions

  • the invention relates to a soil sifting device.
  • the action of breaking these clods down allows the soil to be permeable to both air and water for healthy growth.
  • the gardener may use a garden riddle to remove stones and weeds.
  • This riddle is a hand held tray made of wood and a perforated material that is shaken back and forth, this has the effect of loosening the soil, so the rocks and weeds are left in the tray. This is a back-breaking and labour intensive job.
  • the 'soil sifta' can process soil dug directly from the garden, separating the stones and vegetable matter as quickly as a man can feed the device with material.
  • the present invention comprises a fabricated mesh drum, a frame holding the drum at an inclined angle, an electric / petrol motor or hand crank, with a means of releasing sifted-out material and a mechanism to deliver sifted soil and debris separately to a barrow or other container.
  • the inclined drum with open end uppermost is loaded with garden material to be sifted.
  • the bottom end of the drum is closed except for a labyrinth formed by way of a helical (thread like) surface whose ends overlap by a quarter turn.
  • the gap is a result of the pitch of the helix (150-300mm).
  • the helical back plate By reversing the direction of rotation of the drum the helical back plate actively draws the debris out of the bottom end of the tube, delivering it directly into a barrow or similar container.
  • the 'soil sifta' comprises: A. Rotating mesh drum. B. Helical Back plate. C. Motor or Crank Handle. D. Frame. E. Wheels.
  • Figure 4 illustrates the helical back plate B and how its contra-rotation expels the unwanted retained debris.
