FACILITY FOR LOOSENING FIRM SOILS Russian patent published in 2014 - IPC E02F5/30 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used for loosening layer by layer of firm soils, as well as for removing ice and packed snow on the roads and sidewalks. A facility comprises a frame on which a shaft with teeth fixed on it is mounted in rotation supports, a shaft rotation drive, a bracket rigidly attached to the shaft with axles, on which in the rotation supports gear wheels with eccentric weights are mounted, engaging with a gear wheel mounted on the drive shaft in the rotation supports, and a gear wheel drive. The shaft rotation drive includes a gear pair, the drive wheel of which is connected to the drive shaft through the safety clutch, and the driven gear wheel is connected to the shaft with teeth fixed to it by means of an overrunning friction clutch. Engagement of the overrunning friction clutch is carried out by transmitting torsion torque from the shaft rotation drive.

EFFECT: invention provides increased efficiency of the device operation, reduction of energy intensity of the loosening process of the developed medium and improvement of reliability and life time of the drive components.
