Description

one

The invention relates to the field of agricultural machinery, in particular, to devices for separating botany from root crops, used in machines for harvesting carrots, beets and fodder roots,

The purpose of the invention is to simplify the design and improve the quality of the device.

Fig. 1 schematically shows a device for separating the tops of vegetables from the roots at the root, side view; in fig. 2 - the same, pid from above; in fig. 3 - the same, front view.

The device for separating the tops from the roots at the root comprises a base 2 fixed on the vertical shaft 1, connected by means of a ynpvroro hollow cylinder 3 with two elastic scourges 4, made in the form of rectangular plates that are installed perpendicular to each other I horizontal plane. Elastic whips A are interconnected by means of a fastening element in the form of a bolted joint 5, located in their middle part and inside a hollow elastic cylinder 3, with a loose face, the ends of the scourges 4 protruding from the cylinder 3 are equipped with metal cutting elements 6, with a sharp blade. In the proposed construction, cylinder 3 is provided with two holes made in its wall with holes for fixing one of the scourges in them

4 and can be made, for example, of rubber, fluoroplastic, Teflon.

The device works in the following way.

During the rotation and translational movement of the cylinder 3, the blades of the cutting elements 6, having encountered a bunch of tops, cut it off at a minimum height. The height of the cutting plane depends on the thickness of the elastic scourges 4. Leaving the scapes, interacting with the wide rough bottom surface of the scourges and the semi-circular supporting surface of the cylinder 3, under the action of friction forces are separated from the head of the root crop. The free ends of the scourge 4 easily replicate the soil microrelief and slide along the heads of the roots protruding from the soil, at the same time clearing the leaves of the tops. The copying of the irregularities contributes to the deformation of the elastic walls of the cylinder 3. In known devices, pests are fastened to a disk rotating in a horizontal or vertical plane located at a considerable height from the soil surface. In the proposed device, the scourge placement plane is transferred to the soil surface, which provides the best cut of the tops, since the change of the trajectory of the scourges under the action of centrifugal forces is eliminated, the cut is possible with a single action of the scourge, provided with a sharp blade. Pests are less deformed and less worn.
