Abstract

The invention relates to the field of agricultural engineering, in particular to a device for digging up root crops. The purpose of the invention is to increase work efficiency by providing after-treatment of the heads of root crops during the extraction process from the soil. Disk kopach contains disks 2 and 3 installed at an angle to each other. Disk 2 is made passive, and disk 3 is driven. On the inner surface of the spokes of the drive disk 3 is placed an elastic element 7 in the form of a corrugated tape. The elastic element 7 is mounted on the spokes with the possibility of moving along them with subsequent fixation. When the harvester moves, the disk cops cuts the pile of the root crop and, pinching it between the working surfaces, lifts the layer and squeezes it from the sides without destroying due to the narrowing of the bed between disks 2 and 3. Due to the forced drive of one of the two disks of the copacial there is a slight difference circumferential speeds of paired disks 2 and 3. Bending tape 7, mounted on the drive disk 3, interacts with the surface of the head of the root crop, located between the disks, which compress the layer. This interaction leads to the additional purification of the heads of the root crops in the process of extraction from the soil with a disk hob. 1 hp ff, 3 ill.

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

The purpose of the invention is to improve the efficiency of operation by providing post-dressing of the heads of root crops during the extraction process from the soil.

FIG. 1 shows a disk copach, front view; in fig. 2 is a view A of FIG. one; in fig. 3 - a sweep of the spokes of the rim of the drive disc and a variant of the method of securing the elastic cleaning elements on them.

The disk chuck is made in the form of a stand t, on which two digging disks 2 and 3 are mounted at an angle to each other. Disk 2, which is freely set on its axis of rotation, is made non-driven. The disk 3 is active and driven. Both disks 2 and 3 are made in the form of a rim 4 with a hub 5 interconnected by the spokes 6. Between the spokes 6 on the disks 2 and 3 there are openings for the separation of impurities. On the inner surface of the spokes 6 of the drive disc 3, elastic cleaning elements 7, formed by an elastic tape, are fixed. The elastic element 7 is mounted on the spokes 6 with the possibility of movement along the spokes and subsequent fixation, depending on the height of the position of the heads of the root crops above the soil level. Disk kopach works as follows.

When the harvester is moving, a disk-mounted copy machine cuts a wedge with a rodent and, pinching it between the workers

The two discs of the Kopach there is a slight difference in the circumferential speeds of the paired disks 2 and 3. The bending tape 7 mounted on the drive disk 3 interacts with the surface of the head of the root crop located between the disks compressing the formation. This interaction leads to additional clean-up of the heads of the root crops in the process of extraction from the soil with a disk-shaped digger. 1 h. n. f-ly, 3 ill.

surface, raises the layer and squeezes it from the sides without destroying due to the narrowing of the channel between disks 2 and 3. Due to the forced drive of one of the two Kopach disks, there is a slight difference in peripheral speeds of paired disks 2 and 3. Elastic tape 7 installed on the drive disk 3 due to different peripheral speeds of paired disks 2 and 3 interacts with the surface of the head of the root, located between the disks that compress the layer. This interaction leads to the additional purification of the heads of the root crops in the process of extraction from the soil with a disk hob.
