POTATO DIGGING PLOW Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, equipment for basic soil tillage and digging out of potato.

SUBSTANCE: apparatus has plow body 1 with shortened moldboard, rotor provided with three tiers of working tools and mounted behind plow body 1. Working tools are made in the form of lifting spades 12 and rods 14, 19 fitted with faceplates 16, 20. Working tools of second and third tiers are attached to bearing sleeve 11 of rotor through threaded connection and are fixed by lock nuts 15. In case inclination angle of plates 16,20 must be changed, bearing rods may be turned in mounting opening to loosen lock nuts 15. Faceplates 20 of third tier may be moved relative to their bearing rods along arched path and in direction transverse to said path through the use of slots 22 formed in bearing rods and plates in mutually perpendicular directions. Fastening bolts 21 with nuts are inserted into slots 22. Working tools of second tier are arranged along descending helical lines, when used in plowing mode, and along ascending helical lines, when used in potato digging out mode by turning bearing rods through some angle around their longitudinal axes. Working tools of third tier arranged above moldboard are mainly adapted for forming of potato strip on field surface and for ejecting part of soil from layer.

EFFECT: increased efficiency and enhanced reliability in operation.
