FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, devices for digging up seedlings.

A device for digging up seedlings is known, which includes a plowshare with hinged planks and a vibrator 1.

However, this device is characterized by insufficient destruction of the strata by slats and damage to the root system of the seedlings.

Closest to the invention, the technical essence is a device for digging up seedlings, comprising a digging U-shaped clevis with a share, a shank and fingers, and a vibration drive 2.

A disadvantage of the known device is low productivity when digging up seedlings of fruit crops with a widely branched root system. In addition, when the device deviates from the longitudinal axis of the row of seedlings, the intensity of loosening the soil layer with the root system decreases, and the roots may be damaged by the device’s passive fingers.

The purpose of the invention is to increase the intensification of loosening the soil layer and reduce the damage to the plant root system.

The goal is achieved by the fact that in a device for digging up seedlings, containing a digging U-shaped clevis with a ploughshare, a shank and fingers, and a vibrodrive, the shank is pivotally connected to the clevis and made of pivotally interconnecting loosening and separating parts, the upper surface of each of which has undulating elements, while the fingers are pivotally connected to the plowshare and are connected to the separating part of the shank with the help of a pull.

The ratio of the length of the separating part of the shank to the length of its loosening part is 2: 3

The length of the separating part of the shank to the point of attachment to the length of the separating part of the shank located behind the thrust is referred to as 4: 1.

The wavelike elements of the front loose part of the shank are made with increasing pitch and decreasing height in the course of the technological process, and its separating part is from the point of attachment of thrust in both directions.

The step of the undulating element of the loose part of the shank is made by a large step of its separating part.

Moreover, the ha is fixed vertically, and its length is less than the length of the finger.

FIG. 1 shows a diagram of the proposed device for loosening the soil layer and separation of the root system of plants, side view; in fig. 2 - the same, top view.

The device for loosening the soil layer and separating the plant system includes a fixed ploughshare 1 with an extension 2, attached to the U-shaped bracket 3. At the rear end of the extension 2, with the help of hinges 4, a shank is fixed

from loosening 5 and separating 6 parts, interconnected by means of a hinge 7, to which a connecting rod 8 is fastened to a crankshaft vibrating rod 9. On the back side of the plowshare 1 by means of the hinges 10 are attached the front ends

fingers 11. The rear ends of the fingers 11 through the hinges 12 and 13 and the elastic rod 14 are connected to the back of the separating part 6 of the shank.

On the upper side of the loosening 5 and separating 6 parts of the shank, wavy rubberized working elements 15 are fastened.

A device for loosening soil formation and separation of the root system of plants works as follows.

When the device moves along a row of plants to be dug, the share of ploughshare 1 is buried in the soil to a certain depth and, together with the shackle 3, cut out a rectangular layer of soil with the root system of plants.

As a result, the formation moves up the shank 2 and begins to partially collapse. Further, the formation is exposed to the loosening part 5 of the shank, where further loosening and crushing of the soil layer occurs. At the same time, a smaller amount of soil lumps passes through the loosening part 5 of the shank and falls to the bottom of the furrow, and most of it goes to the separating part 6 of the shank, where further loosening of the reservoir occurs and the root system of the plants is separated. At the same time, the soil lumps are sifted through the separating part 6 of the shank, and the root system of the plants is pushed by rubberized working elements 15 onto the surface of the floor. During operation, the crank crank vibrator 9, the separating part 6 of the shank interacts with the bottom of the furrow through the elastic rods 14 and fingers 11. Due to the different degree of elasticity of the gasket 14 and fingers 11, which in the gasket 14 is larger than that of the fingers 11, the separating part 6 of the shank is approximately the same, regardless of the depth of excavation or physical and mechanical properties of the reservoir. The device for loosening the soil layer and separating the plant root system allows intensively destroying the soil layer with the plant root system without damaging it.
