摘要:
Paddle drill for grubbing relates to a drilling tool and can be applied mainly for grubbing overgrown thorns, cherries and plums, but they can be uprooted and growth of other species of trees and weeds with a solid stem or root. The purpose of the utility model is to increase the productivity and reducing the diameter of the borehole at uprooting. This object is achieved except borer and the direction of the drill stem along overgrown via holes located at the spot picker. The diameter of the hole will thus slightly larger than the diameter shoots. For kochevki seedlings, for example, a diameter of 17 mm is sufficient drill diameter of 80 mm. Application vane grubbing enables the drill to increase productivity and reduce the damage to the roots of fruit trees at about uprooting them compared with the well-known blade stump drill or a spade. FIG. 1 shows an auger vane for grubbing with the blade in the form of one turn of the auger. Vane for grubbing drill includes: a drill body - 1, the blade - 2, a guide hole - 3, the exit hole of the land of the drill body - 4. FIG. 2 shows a blade for grubbing auger during uprooting a tree shoots, where the drill body - 1, the blade - 2, shoots barrel - 5, the root - 6. The proposed utility model borer absent and in its place there is a guide hole - 3. No borer It makes it much easier to change the direction of drilling while grubbing, and the guide hole - 3 at the same time, working with its member stem shoots - 5, directs the drill stem along the overgrown tree to its very roots. When uprooting of FIG. 2 in the first guide hole - 3 is inserted into the cut at a small height from the ground trunk overgrown - 5, then the well is being drilled when the drill rotates. During drilling, drill, guided by the guide hole - 3 moving along the bends and deviations in the vertical trunk overgrown - 5, reaches the root - 6, which is a growth and exposes root - 6. Boer retrieved from the well. Long bit root - 6 pererubaet near wellbore at two
