Abstract
A weed remover for removing weeds comprising a tube comprising a main portion and a bottom portion at a distal end which is insertable into soil to capture a core sample thereof. The tube is formed of a static portion and of a moving portion which complements the static portion to form the tube, wherein the tube comprises an inner diameter smaller at the distal end than in the main portion. At the distal end, the moving portion extends over an angular range from about 90° to about 150° and the static portion extends over a complementary angular range to form a contour. The bottom portion is formed of a succession of projections and recesses around the contour to form a cutting edge.
Claims17
A weed remover for removing weeds from a ground, the weed remover comprising:
- a tube comprising a distal end which is insertable into soil to capture a core sample thereof, the tube being formed of a static portion and of a moving portion which complements the static portion to form the tube, wherein the distal end of the tube extends inwardly to make an inner diameter of the tube smallest at the distal end of the tube, wherein at the distal end, the moving portion extends over an angular range from about 90° to about 150° and the static portion extends over an angular range which is complementary to the angular range of the moving portion to form a 360° contour of the tube at the distal end, and
- a mechanism to move the moving portion distally from the static portion to release the core sample of soil captured in the tube.
