SU1207416A1 - Rotary working member for potato harvester - Google Patents

Description

The invention relates to potato harvester technology, namely to the arrangement of rotary separating tools intended for loosening the soil layer and separating shallow soil.

The aim of the invention is to ensure reliable operation by improving the self-cleaning of the shafts and reducing the damageability of tubers.

FIG. 1 shows a carto, fel- sweeper with a rotary working body, side view; FIG. 2 is the same, top view; in fig. 3 - blade disc, side view; in fig. 4 sleeve.

The rotary tool includes shafts 1 and 2, on which the blade disks 3 and the sleeves 4 are alternately mounted, the blades 5 curved in the direction opposite to the rotation of the disks.

The disks 3 and the sleeves 4 of each subsequent section are located respectively opposite the sleeves and disks of the previous one. The ribs of the sleeves 4 and the corresponding blades of each sec1207416.

tions are directed in the same direction, and the edges of the sleeves and blades of the subsequent sections are offset relative to the previous ones so that when the opposite edges and blades of the plane of the axes of the sections pass, the corresponding blades and edges of the sleeves of the adjacent section

10 relative to a friend.

Rotational working body works as follows.

The ploughshare breaks through the formation and transfers the mass to the rotary tool, 15 when the sharp edges of the sleeves 4 are combined, on which the vegetation is wound, with blades 5 of the disks 3, it breaks off. Thus, the rotary working body is designed

20 for loosening the potato bed of layers, separating the small soil, self-cleaning plant residues.

The curved blades against the direction of rotation eliminate the impact of the ends of the ends on the tubers, as a result of which their damage is reduced.
