The invention relates to machines for the development of agricultural use of areas covered with shrubs and low forests, littered with stones, and can be used in the forest industry.

Known grubber, including self-propelled shchasi, on the frame of which is strengthened the working body with undercutting knives, made in the form of a system of separating keys, and cleaning rotors 1.

The disadvantage of this upraiser is incomplete cutting of the roots, jamming of the shrub mass and low productivity.

Also known is a grubber that includes a self-propelled driver, on the frame of which a working body is fixed with undercutting knives, made in the form of a system of separating keys, in front of which there is a flat blade with ejector pivotally mounted on it and cleaning rotors 2.

The disadvantage of this lifter is jamming with stones and other strong objects of the front part of the keys relative to the fixed blade of the flat cutter.

The purpose of the invention is to increase reliability by preventing seizure of stones and other solid objects between the toes of the separator key.

The goal is achieved by the fact that elastic plates are installed between the flat-cutting knife and the toes of the separating key, some of which are attached to the pushers, while others are cantilevered attached to the flat-cutting knife and the free end is supported on the separating keys.

FIG. 1 shows a rooting device, a general view; in fig. 2 is a view B in FIG. one; in fig. 3 shows section A-A in FIG. 2; in fig. 4 — node 1 in FIG. 3

The lifter consists of a frame 1, a flat-cutting knife 2, separating keys 3, On a flat-cutting knife 2 elastic plates (rubber) 4 are cantilevered by means of an axis 5, resting their free ends on the separating keys. Elastic plates 7 are attached to the ejector 6. The elastic plates 4 and 7 are preferably mounted on a common axis 5.

Flat cutting knife 2 cuts a layer of soil. Then, by means of a rigid articulated ejector 6, the ousted mass enters the separating keys 3. Elastic plates overlap areas where any jamming is possible when the separating keys work or during stopping and thus prevent stones from entering between the cutting knife and the separating keys.

The use of this device allows you to significantly increase the reliability of the unit and reduce the complexity of servicing it in the process of work, i.e., to ease the working conditions of the staff.
