WORKING EQUIPMENT OF HYDRAULIC EXCAVATOR Russian patent published in 2014 - IPC E02F3/28 

FIELD: construction.

SUBSTANCE: ripper tip is made with a U-shaped stand and a bracket at the rear side, and also by hydraulic fixators in the bracket and in the U-shaped stand. The ripper tip is fixed to the handle by one hinged joint together with the bracket and as capable of disconnection with a crank with the help of a hydraulic fixator in the U-shaped stand. Also with the possibility of connection in non-working condition to a hinged joint on the handle with the help of a hydraulic fixator in the ripper tip bracket. In working position, i.e. during tillage, the ripper tip is connected to the crankshaft by the hydraulic fixator in the U-shaped stand. Hydraulic fixators in the bracket and in the U-shaped stand of the ripper tip installed in the transverse plane of the ripper tip comprise hydraulic cylinders of double-sided action. Stems of hydraulic cylinders are connected to sliding fixators capable of entering the hinged joints on the handle and in the crankshaft.

EFFECT: reduced costs for manufacturing, reduced energy losses for process of excavation and tillage, simplified assembly and disassembly of tillage equipment.
