CUTTING DEVICE Russian patent published in 2017 - IPC B02C18/18 

FIELD: machine engineering.

SUBSTANCE: group of inventions can be used for grinding wood and/or soil. The cutting device comprises at least one cutter holder having at least one groove for partial placement of base element and at least one longitudinal center line. The line consists of at least two sections oriented at angle to each other. In this case, the groove is defined by at least two partial areas of the cutter holder surface that are arranged at an angle from 75 to 105° to each other. The base element for the grinding rotor contains at least one supporting portion which is intended for connection with said cutting device and having at least one longitudinal center line. There are two sections in the middle line passing directly along at least one surface of the supporting portion and oriented at angle to each other. In addition, the surface of the supporting portion has at least two partial areas which are arranged at an angle of 75 to 105° to each other. The system comprises said base element and the cutting device attached thereto.

EFFECT: proper centring and holding of the cutting device that greatly reduces the operating costs.
