摘要：The object of research is vibrational feeders with vibro-impact adaptive drive, the characteristic feature of which is the multifrequency excitation and self-adjusting of the oscillations parameters, including the frequency spectrum, to change the mass of the technological load. The basis of the problem solution is the excitation of vibro-impact oscillations of the working body (tray) of the feeder, at which in its vibration drive the resonant frequency oscillations are realized, the intensity and frequency spectrum of which increase with increasing the technological load on the feeder tray, which distinguishes such vibrators from those used in typical feeders. Vibro-impact systems with such vibro-excitement with parameters and dynamic loading, identical with analogues, have, depending on their purpose, from 3 to 8 times less power consumption, and from 3 to 5 times increase in the intensity of oscillations. At the same time, due to polyfrequency excitation, the mobility of the technological medium that is being processed is improved, which is especially important for the control of freezing and adhesion of materials in the bunkers, or in the pillar of the reflacted rock mass during its output by the vibrating feeders from the chambers of the wining blocks at the underground mining of minerals.
