Abstract
A digging and planting machine is provided having a tubular digging and planting tool, and at least two surface-detecting and signalling means for sensing the surface of the ground adjacent the digging tip of the tool, preferably on opposed sides of the digging tip, thus gauging the lay of the surface, so as to ensure that the digging tip provides and a plant is fed to a planting hole of the desired depth.
Claims17
A digging and planting machine comprising, in combination, a vehicle, and, carried on the vehicle, a digging and planting tool including a tubular member movable between a lower position partially embedded in the ground and an upper position above the ground, and having an open digging and planting tip end, for digging a hole and conveying a plant to the hole;
- means for moving the tubular member between its lower and upper positions;
- at least two surface-detecting and signalling means arranged on two opposed sides of and adjacent to the tubular member, for sensing the surface of the ground on said opposed sides adjacent to the digging tip end of the tubular member and signalling a control means;
- said control means operatively connected to each surface-detecting means and said means for moving said tubular member, said means for moving said tubular member continuing digging movement of the tubular member until at least said two surface-detecting means have contacted the ground surface, thereby gauging the lay of the surface of the ground on opposed sides of the tubular member between the surface-detecting means to provide a hole of the desired depth according to the lay of the ground.
