DEVICE FOR DEBRANCHING LIVING TREES Russian patent published in 2018 - IPC A01G23/95 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for debranching living trees. Device can move up and down the tree autonomously and has an upper cutting unit comprising three blades and below it a lower cutting unit comprising two blades. Total of five blades are arranged so that they cover the full girth of the tree. Two blades in the lower cutting unit are horizontally offset so that their end portions can overlap. To move the device along the tree trunk there are two belt drives which press against the tree and are both driven by a single hydraulic motor. Upper cutting unit with its three blades can move horizontally as a whole, so that when the device is moved and encounters thicker or slightly bent parts of the tree trunk it can give way in order to prevent the bark from being damaged by the blades.

EFFECT: preventing the bark from being damaged by the blades.
