METHOD OF EXCITING MECHANICAL VIBRATIONS OF POWER FACTORS WITH CONTROLLED PARAMETERS Russian patent published in 2018 - IPC B06B1/16 

FIELD: machine building.

SUBSTANCE: invention relates to vibration technology, in particular to the technology of the agro-industrial complex, and can be used at grain processing enterprises in technological and transport equipment, as well as in other industries related to the processing of bulk materials. According to the invention, in a four-balanced vibration exciter, which excites oscillations of force factors according to an asymmetric law, the change in the direction of the largest force factor in absolute value by the opposite is achieved by changing the initial position of slow-moving unbalances.

EFFECT: technical result is a variation in the speed of transportation and higher efficiency of separation of grain mixtures.
