CRUSHING BUCKET Russian patent published in 2024 - IPC E02F3/40 B02C1/00 B02C19/22 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to a crushing bucket and is designed as a reverse bucket designed for crushing stones and other materials. The crushing bucket, on both sides of which there are lateral reinforcing plates, contains rotating shafts on which cutters and hydraulic motors are installed, connected to the rotating shafts through chains by means of double chain gears. In the side reinforcing plates, thrust end bushings are installed, into which rotating shafts with thrust ball sliding mechanisms are inserted, installed in spherical end grooves made in the rotating shafts with a depth equal to 1/3 of the diameter of the thrust ball of the sliding mechanism. The rotating shafts are made with cutters equipped with teeth, and in the rear part of the bucket there is an ejection hole in which sharpened knives are installed.

EFFECT: reduction in the coefficient of friction on parts operating under load, as well as improved grinding of the ejected material.
