SHAKER MACHINE Russian patent published in 2012 - IPC E21B21/10 

FIELD: mining equipment.

SUBSTANCE: The invention relates to mining equipment, in particular, to shaker machines which create oscillations in liquid during direct and indirect flushing of mining equipment and well bottom, during bed stimulation and discharge of producing energy. The device comprises a frame where a rotatable crankshaft is installed on the axis. Furthermore, valves are fixed with pins at both ends of the crankshaft. The installation of valves at upper and lower part of the crankshaft allows to oscillate the liquid in both directions during direct and indirect flushing. The lower valve creates a hydraulic resistance to the liquid flow, reduces oscillation frequency for the upper valve, thus increasing the oscillation amplitude of the liquid.

EFFECT: production of the said device.
