RESONANT VIBRATION MACHINE FOR UNLOADING LOOSE CARGOES FROM GONDOLA CARS Russian patent published in 2000 - IPC

FIELD: materials handling facilities. SUBSTANCE: invention relates to mechanization and intensification of unloading of frozen or caked materials from vehicles. Proposed machine has bearing frame 1 for transmitting vibrations in continuous mode through upper binding to opposite walls of body supply platforms 2. Vibration exciters 4 are fixed on each platform symmetrically relative to common center of mass. At least two spring- loaded inertia masses 6 are installed on support platforms from both sides of vibration exciters to form two-mass centered system. Inertia masses are furnished with strikers 7 for interaction with anvils 8 installed symmetrically relative to vibration exciters on above-indicated support platforms. Anvils are installed for resilient displacement along vertical axes passing through centers of mass. Summary rigidity of resilient elements is chosen to provide resonant vibration of inertia masses. EFFECT: reduced energy consumption without increasing mass of machine. 2 dwg
