The invention relates to agriculture, mechanical engineering, in particular to devices for extracting plant roots from the soil, used, for example, in surveying vineyards for phylloxera infestation.

A device for extracting plant roots from soil is known, which contains a root-removing element fixed to the frame, in front of which, on its two sides, root-cutting knives are installed. The root-i extracting element is made in the form of two cheeks, between which moving lifting fingers l are mounted.

The specified device is unreliable in operation, since the working parts moving in the soil are subject to rapid wear.

Closest to the present invention is a device for extracting plant roots from the soil, which is fixed to the frame by means of its own rack: a non-removing element, in front of which, on its two sides, root-cutting knives are installed. The root element of the device is made in the form of a curved tooth 2.

The disadvantage of the known device is unreliable fixation, cutting off the roots on the root-removing element, which leads to incomplete extraction of the roots from the soil, and this in turn leads to an increase in the number of passes of the device along one treated area, i.e. to increase labor costs.

The purpose of the invention is to reduce labor costs for extracting plant roots by increasing the completeness of their selection.

The goal is achieved by the fact that the root-removing element is designed in the form of a fork with adjoining ones and located along an arc.

teeth and is provided with a bracket located above its arc, located on its stand, the free ends of which are directed toward the root-cutting knives.

The device is made in the form of a root-removing element fixed on the frame 1 by means of its stand 2. Root-cutting knives 3 are installed in front of it, on both sides. The root-removing element is designed as a fork with teeth 5 along the arc, and on the stand 2 is located bracket 6, the free ends of which are directed toward the root-cutting knives 3.

The device works as follows.

During the working forward movement of the device along rows, for example, grapes, the recessed knives 3 cut its roots, after which segments of the roots are removed by teeth 5 and move up to their brackets up along their surface. After a sufficient amount of them has been accumulated in the area between the bracket 6 and the ends of the teeth 5, the device is excavated from the soil and the segments of roots are removed to be examined for contamination, for example, with phylloxera.

Matching teeth 5 along the arc increases their rigidity and reduces the possibility of soil unloading in front of the root-removing element. The presence of the bracket 6 with cantilever ends directed towards the knives 3 increases the number of selected roots in one cycle of the device, while performing the root-removing element in the form of a fork, improves the fixation of the roots, their selection, i.e. reduction of losses, which ultimately leads to lower labor costs for extracting the roots of grapes.
