This invention relates to machines for processing and sorting of root and tuber crops.

The purpose of the invention is to increase productivity and quality.

FIG. 1 is a schematic illustration of a device for sorting of root and tubers, top view in FIG. 2 - wo the same on the side; in fig. -3 - view A in FIG. 2

The device for harvesting of root and tuber crops consists of flexible infinite elements 1, which form a separation of gaps 2, a pair of upper main 3 and lower additional.4 rotating pulleys.

In the place of formation of the separation gap, parts of the branches 5 and 6 are located one below the other with a minimum clearance of about.

Part of branch 5 rests on the upper pair of rotating pulleys 3 on the inner side, and part of branch 6 on the lower pair of pulleys A on the outer side of the endless element

Each lower rotating pulley 4 is located under the lower branches of the elements 1 between the main pulley II 3.

The actuator 7 is designed to transmit rotation to the drive shaft 8.

The branches of the flexible elements in the place of the separation gaps move in opposite directions.

The device works as follows.

The root crops to be sorted are fed to the sorting surface (not shown. Under the action of speed v, the roots are pulled apart over the sorting surface and oriented relative to the separation clearances. Since they are sorted

root crops have a rounded forn, their ends or parts of the surface are located inside the separation gaps exposed to

each x parts of elastic elements having the opposite velocity V. At this time, there is a movement of the roots inside the separation gap, namely the rotation

relative to the longitudinal axis with simultaneous movement along the direction-. the speed of v. Roots, with transverse dimensions, smaller than the separation gaps, pass through them, and with larger transverse dimensions move to the edge of the surface and are dropped by the uppermost rotating pulleys.

Thus, the sorted root crops are subjected to the additional impact of moving

in the opposite direction of the branches of the elements, which increases the intensity of the separation process.

As a basic model, a sorting machine of the PSK-6 root crops sorting station can be accepted.

The technical and economic effect from the use of the proposed device is created due to the more active influence of the parts of the branches of the endless elements on

the sorted mass when it is on the sorting surface, which eliminates various shaking, receiving and guiding devices, shortens the length

infinite elements, and the tensioning device can be made common to all rotating supports, in addition, it is possible to self-clean the infinite contour from the inside and simplify the design as a whole.
