ROLLER OF IMPACT ACTION 3 Russian patent published in 2011 - IPC E02D3/46 E01C19/41 

FIELD: machine building.

SUBSTANCE: roller of impact action 3 includes dynamic rotor consisting of interconnected rolling hollow tubes with working element secured on ends. A hammer is installed inside each pipe. The hollow tube proper and the hammer installed in it are designed for temporary attachment of the hammer for its rise at rotation of the roller, for release of the hammer in an upper position and its transfer inside the pipe downward. When the hammer drops, it strikes a back side of the working element. The dynamic rotor is installed inside a steel cylinder casing and rolls along internal surface of the casing in the direction perpendicular to geometric axis of the cylinder casing. The cylinder casing can be made solid, thru and equipped with lugs in roller of impact action 3. At progressive motion of a tractive unit the dynamic rotor rolls along internal surface of the cylinder casing and transfers the latter. Thus there are made periodic impacts against internal surface of the steel casing.

EFFECT: steel cylinder casing performs assigned operation under effect of impact.
