FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to the after-treatment of root crops from foliage on the root, used in harvesting machines, for example, sugar beet.

The purpose of the invention is to improve the quality of post-treatment of root crops from tops, an increase in the service life and a reduction in the consumption of material hit.

: FIG. 1 shows schematically a pre-cleaner of root crops from foliage on the vine, 10 front view; in fig. 2 - the same, side view.

The after-cleaner of root crops from a foliage on the root consists of a horizontal shaft 1, to which the flexible elements 2 are perpendicular to the radius with one end, their longitudinal axis located in: the plane of rotation. At the other end of the flexible elements 2, with the aid of the bent brackets 3, the billes 4 are attached, which have a longitudinal groove 5. The material's stiffness hit significantly more than 20 the rigidity of the material of the flexible elements. Each bracket 3 is provided with an additional load 6.

The post-cleaner job is as follows.

the weight 6 mounted on the bracket 3. Under the action of centrifugal forces from the side of the flexible element 2 and the load 6, the first tends to bend forward in the direction of rotation of the shaft 1, thereby retaining its original shape. This allows the flexible element 2 to serve for a sufficiently long time and reliably, especially since it does not experience direct impacts from the roots. Due to the high stiffness of the blow 4, they are slightly bent during operation, which does not cause permanent deformation in them. However, under the action of the frictional forces, the blows 4 wear out and shorten. The restoration of the normal length of the billet at the expense of the available stock is carried out by loosening its attachment to the bracket 3 and its movement in the groove 5.

Claims (6)

1. An after-cleaner of root crops from a foliage on the root, including a horizontal shaft connected to billes located along it, the longitudinal axes of which are located in the plane of their rotation, while thirty When the movement of the agricultural 25 free working ends hit forward in the course of rotation of the shaft, characterized in that, in order to improve the quality of tertiary treatment of root crops from tops, increase service life and reduce material consumption, beat, bond with the shaft is made in the form of flexible elements with which the aftercleaner is provided mounted on a shaft, and the other connected to the non-working end of the bill by means of a bracket. 2. A cleaner according to claim 1, characterized in that the bead is made of a material having a stiffness greater than that of the material of the flexible member carrying this bil. 3. A cleaner according to claim 1, the shaft 1 that distinguishes the unit is rotated against its movement, and the billes 4 wrap the tops of the tops of the root crops, and also effectively pick the tops and its remnants located near and on the soil surface. This happens because the billes 4, facing their free working end forward along the movement of the unit, not only move the tops in this direction, but also simultaneously lift it. When interacting with the head of the root crop bily 4, it and mainly flexible element 2 are bent. At the same time, the speed of the free working end of the bilie 4 falls, and with it the efficiency of cleaning ki head of the root of the tops. However, 40 with the fact that the flexible element is mounted on due to the force of the load 6, the gesture-shaft is sufficiently perpendicular to its radius, bile This bile 4 is said to have additional force, leading to a stronger impact on the root crop, not only at the moment of impact, but also during the post-impact period, and as a result, to the best post-treatment of root crops from foliage. At the end of the interaction, bile 4 with a root crop, it takes up its initial position relative to the shaft, which is aided by 4. A cleaner according to claim I, characterized in that the longitudinal axis of the flexible element is located in the plane of its angle. 5. A cleaner according to claim 1, characterized in that the beater has a straight shape, and its attachment bracket is curved in the plane of rotation. 6. A cleaner according to claim 1, distinguishes the attachment of the flexible element 2 perpendicularly to the fact that the blade is provided longitudinally with the radius of the shaft 1 with the longitudinal axis of symmetry of the flexible element 2 in the plane of its rotation, and with such a groove for fixing it on the bracket with an adjustable offset relative to the latter. 0 0 five the weight 6 mounted on the bracket 3. Under the action of centrifugal forces from the side of the flexible element 2 and the load 6, the first tends to bend forward in the direction of rotation of the shaft 1, thereby retaining its original shape. This allows the flexible element 2 to serve for a sufficiently long time and reliably, especially since it does not experience direct impacts from the roots. Due to the high stiffness of the blow 4, they are slightly bent during operation, which does not cause permanent deformation in them. However, under the action of the frictional forces, the blows 4 wear out and shorten. The restoration of the normal length of the billet at the expense of the available stock is carried out by loosening its attachment to the bracket 3 and its movement in the groove 5. Invention Formula 1. An after-cleaner of root crops from a foliage on the root, including a horizontal shaft connected to billes located along it, the longitudinal axes of which are located in the plane of their rotation, while 5 free working tips hit facing with the fact that the flexible element is mounted on the shaft perpendicular to its radius, 4. A cleaner according to claim I, characterized in that the longitudinal axis of the flexible element is located in the plane of its angle. 5. A cleaner according to claim 1, characterized in that the beater has a straight shape, and its attachment bracket is curved in the plane of rotation. 6. A cleaner according to claim 1, characterized in that the beater is provided with a lengthwise nick groove for fixing it on the bracket with adjustable overhang relative to the latter. Phage.1
