Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to reduce damage to root crops. A device for extracting root crops from the soil comprises a housing 1 carrying counter rotating rollers 5 and 6, on which root cones are fixed with their bases 9. Each of the cones is made of a metal base 9, a metal tip 11 connected by a stepped metal cable 10 with a decreasing cross section in the direction to the tip 11. The outer part of the cone in its middle part is made of an elastic material. On the body 1, the undermining paw 13 is rigidly fixed, located along the longitudinal axis of the device. In the process of operation, the paw 13 digs up the roots, and the cones, loosen the soil with tips 11, with their middle parts extract these roots from the soil. 2 Il.

The invention relates to agricultural machinery, in particular to devices for extracting root crops from the Soil used in root-harvesting machines.

The purpose of the invention is to reduce damage to root vegetables.

FIG. 1 shows a schematic of a device — oystobo for extracting root crops from the soil, top view; in fig. 2 is a section A-A in FIG. one.

A device for extracting root crops contains a reducer, which consists of a core 1, a cover 2 with a seal 3, two pairs of bearings 4, on which

The harvesting unit focuses on the rows of harvested root crops in such a way that the longitudinal axis of the device approximately coincides with the conventional axis of the harvested row. Undermining paw 13 is completely buried, the drive of active cones is activated and the harvesting unit starts moving along the rows to be harvested. Root crops cleared of tops are burrowed by paw 13 and due to translational

10, the movement of the harvesting unit is agitated, ayut-s along its upper surface, described by a radius R and smoothly rising to the surface of the soil. The initial part of the cones, the flexible end playing the role of loosening the upper layer of the soil, contribute to the exit

the driving shaft 5 and the driven shaft 6 - gear-,

Sh. To transfer the torque from the root to its surface, {the shaft is driven onto the driven shaft 5, a bevel gear 7 is located inside the gearbox housing 1, and a semi-: coupling 8 is mounted on the shaft end 5 s

the root of the cones).

with elastic surface

The root crop located between the cones in the middle part of the device rises to the surface not only by paw, but also

: outside gearbox. The counter-JQ rotating in opposite directions is a false end of the shaft 5 by means of thread-cones (provided that the connection is over the top of the joint, it is attached to a cone, which consists of a metal base: neither 9 nor the metal cable 10, made in the form of a stepped rod and fixedly connected to the base 9, a metal tip 11, fixedly connected to the cable 10, an outer working surface 12 made of an elastic material, for example rubber, vulcanised onto the base 9 and the cable 10, when., .., .., ,

the latter, made in the form of a step-30 of this, on the body is rigidly fixed to the clamped rod, fixedly connected to the main paw, located along

The longitudinal axis of the device, characterized in that, in order to reduce damage to root crops, the top and bottom of the cone are made of metal and are connected to each other by means of a metal stepped cable along the axis of the cone, with a decreasing cross-section in the direction to the top of the cone, while The part of the latter, in its environment. The device for extracting root crops from its 40 part, between the top and bottom, works as follows. It is made of elastic material.

Invention Formula A device for extracting root crops from the soil, comprising a body carrying two oppositely rotating shafts, on each of which a cone is fixed by its base. : by its large base 9, and the thin end of the cable is fixedly connected to: the tip 11. In the lower part of the gearbox housing 1 there is a fixedly passive undermining paw 13, made of metal. The upper surface of the paw is described by radius R, and the lower one, the paw has no sharp edges. 35 The harvesting unit focuses on the rows of harvested root crops in such a way that the longitudinal axis of the device approximately coincides with the conventional axis of the harvested row. Undermining paw 13 is completely buried, the drive of active cones is activated, and the harvesting unit starts moving along the harvested rows. Root crops cleared of tops are burrowed by paw 13 and due to translational the movements of the harvesting unit are agitated, ayut-s along its upper surface, described by a radius R and smoothly rising to the surface of the soil. The initial part of the cones, the flexible end playing the role of loosening the upper layer of the soil, contribute to the exit  , root vegetables on its surface, the root of the cones). with elastic surface  ., .. .. ,,  In this case, a podkapapayuschaya paw rigidly fixed, located along the Invention Formula A device for extracting root crops from the soil, comprising a body carrying two oppositely rotating shafts, on each of which a cone is fixed by its base.
