Claims

1. Device for cutting tree-shrub and stem vegetation, comprising a supporting element with means for connecting to the equipment of the traction transport machine mounted on said element, at least one vertically oriented shaft connected to the drive, on which a disk with cutting elements is mounted on the side its lateral surface, which are located with a step-angular displacement relative to each other, characterized in that the said disk is provided on the side of its end surface, opposite bearing the location of the bearing element and the shaft of rotation, cutting and grinding knives, these knives are offset relative to each other in radial-angular directions and have cutting edges oriented to the axis of rotation of the shaft at an angle α = 90 ^° or α <90 ^° , while the diameters described by the end sections of the cutting edges of these knives are located in at least one plane parallel to and displaced in a level below the corresponding plane in which the diameter of the circumference described by the end sections of the cutting edges is located s placed on the side of the side surface of the disk, with the ratio of diameters
D ₂ / D ₁ ≤ 1,
where D ₂ is the diameter described by the end sections of the cutting edges of the cutting-grinding knives, extreme from the side of the mentioned end surface of the disk with respect to its side surface;
D ₁ - the diameter described by the end sections of the cutting edges of the cutting elements from the side of the side surface of the disk,
moreover, the vertices of the mentioned angles at α <90 ^° are turned towards the supporting element with a rotation shaft mounted on it or to the said side and in the opposite direction to the area of the planes of the lower level corresponding to the location of the described diameters of the end sections of the cutting edges of the cutting-grinding knives.

2. The device according to p. 1, characterized in that the cutting elements from the side of the side surface of the disk are made in the form of plate knives or teeth forming a sawtooth edge.

3. The device according to claims 1 and 2, characterized in that the cutting and grinding knives are located in the corner zones of the end surface of the disk located between the corner zones corresponding to the displacement of the cutting elements of the disk from the side of its side surface when the latter are made in the form of plate knives.

4. The device according to claim 1, characterized in that the supporting element is formed by a box casing, the front side of which is open from the side of the protruding part of the disk with cutting elements and cutting and grinding knives, the opposite surface is formed by elastomeric shields, while on the side of one of sidewall of the casing, its upper surface is provided with a protruding trapezoidal visor, paired with the indicated surface with a large base.

5. The device according to p. 1, characterized in that the cutting and grinding knives have a predominantly V-shaped contour, the open part of which faces the opposite side from the end surface of the disk to the plane of the lower tiers corresponding to the location of the described diameters of the end sections of the cutting edges data knives.
