COMBINED CULTIVATOR FOR cultural care of forest plantations

摘要

The invention relates to forestry engineering, in particular to the instruments of cultural care of forest plantations. Technical result is achieved by the proposed combined cultivator for agrotechnical care forest crops planted in rows, comprising a frame, symmetrically placed thereon relative to the axis of symmetry of the frame, and rotating working Tine bodies. For a good penetration into the soil rotational working bodies in front of them, on the front bar of the frame secured two sided ploskorezhuschie paws, the cutting portion being located at an obtuse angle to the axis of symmetry of the frame of the cultivator, at a distance from each other equal to: L = 2 _(k + R k ), where k - deviation from the axis of the row plants, occurs when planting crops; R _k - the radius of the plant's root system. Consistently sided ploskorezhuschimi paws on the middle of the frame tool bar installed rotary working bodies, and for them to handle parts of the neighboring row spacing, tool bar at the rear of the frame, two rows are fixed arched feet. In general, the proposed combined cultivator for agrotechnical drifts in forest crops, due to a combination therein various working elements (rotary rippers, and ploskorezhuschih lancet paw) significantly reduces the energy and material costs for growing forest plantations.
