Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular to working bodies for the extraction of root crops. The goal is to increase work efficiency and reduce energy consumption. The device contains a packer containing a drive disk mounted at an angle to each other and a passive disk 3. The disks have cycloidal needles 5 and S-shaped sections of the rim between them. The spokes of the passive disk 3 have a concave surface in the direction of the working movement of the device, and each portion of the S-shaped rim is concave toward the center of the disk is located in front of the rim interface section, which is convex from the center of the disk. 2 Il.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to working bodies for extracting root crops.

The goal is to increase work efficiency and reduce energy consumption.

Fig 1 shows the root-extracting device front view in Fig 2 the same, view A in Fig 1 (passive disk)

The root-extracting device contains hoppers 1 including drive 2 and passive 3 disks installed at an angle to each other. Drive disk 2 is rotated by means of gear 4 Disks 2 and 3 have cycloidal spokes 5 and S-shaped sections of the working edge of the rims 6 between them. The spokes of the drive disk 2 have a concavity in the course of its rotation, and the front part of the S-shaped

the rim section — the protuberance of the Spoke 5 of the passive disk 3 along its rotation is convex, and the front part of each S-shaped rim section 6 is concave

Root extracting device works as follows

When the kopac 1 moves forward, the drive-digging drive 2 and passive 3 disks, rotating in the direction of movement of the kopach with different angular speeds (a), are buried to the working depth and undermine the root layer of the soil. In this case, the disk 2 is forcibly rotated by the gearbox 4, and the disk 3 is self-rotated by capturing the undermining layer with soil. The bulge of the spokes 5 of the passive disk 3 along its rotation (which turns in the digging area from the concavity in the direction of translational movement of the copacot v) increases

exciting drive ability. This increases the angular velocity of rotation of the passive disk, the effectiveness of its effect on the treated formation and increases the root-removing force of the copacach. In addition, the S-shaped sections 6 of the rim of the passive disk work as soil pickers, which also increases the angular velocity of its rotation. At the same time, the bulge of the spokes 5 of the passive disk increases the activity of its effect on the root crop through the soil layer, contributing to its intensive release in the digging zone from the reservoir being worked out. At the same time, in the zone of transfer of the root to the separating organs, there is an intense descent from the disc of trapped soil and plant mass. This helps to reduce the energy intensity of digging root crops by improving the self-cleaning conditions of the passive disk.
