BRUSHWOOD CUTTING APPARATUS Russian patent published in 2008 - IPC A01G23/06 

FIELD: forestry.

SUBSTANCE: apparatus has boom pivotally fixed for performing pendulum motion on attached frame, working tool formed as disk saw, drive for working tool, and system designed for feeding of arboricide mixture and equipped with arboricide mixture feeding valves. Working tool is driven by hydraulic motor through reducer. Hydraulic motor with reducer is positioned within boom cavity, and working tool is fixed on output shaft of reducer. Vertical column is positioned on top the boom and axially aligned with output shaft of reducer. Mechanism for bending of brushwood trunks during cutting thereof is positioned in upper part of vertical column. Said mechanism comprises supporting disk rigidly fixed on vertical column. Cylindrical sleeve mounted with its base on supporting disk is designed for moving in horizontal plane and equipped with circular recess in its base. Cylindrical sleeve is spring-loaded by means of safety springs on every side relative to vertical column. Mechanism for bending of brushwood trunks is connected to system for feeding of arboricide mixture through hollow pushing ring on which mixture feeding valves are positioned and which is fixed on outer wall of cylindrical sleeve. System for feeding of arboricide mixture is formed as cylindrical reservoir rigidly fixed on upper free end of vertical column. Cavity of cylindrical reservoir is connected through flexible pipeline to hollow pushing ring. Said valves are joined through flexible pipelines with flexible pipes curved opposite to direction of rotation of disk saw and fixed on disk positioned in base of vertical column. Protective housing fixed on outer vertical wall of cylindrical reservoir is formed as truncated cone with its base directed downward.

EFFECT: increased efficiency by eliminating the possibility of jamming disk saw to thereby improve cutting conditions, effective utilization and saving consumption of arboricide mixture.
