HOPPER FOR LOOSE MATERIAL Russian patent published in 1996 - IPC

FIELD: storage and dispensing of difficult-to-flow materials. SUBSTANCE: hopper for loose materials has bridge breaker with disks 3 secured with tilting on cylindrical support sleeve 4 enclosing shaft 2. Bridge breaker has vibration exciter with central helical gear 5 and unbalanced planet pinions 8 coming into meshing with gear 5. Planet pinion shafts 10 are connected with vibration exciter housing 11 through overrunning mechanism 6. Resilient members 12 and 13 are installed between vibration exciter housing 11 and central helical gear 5. Disks 3 execute complex motion: reciprocating-rotary motion and reciprocating axial motion are superimposed on rotary motion. Geometrical characteristics of trajectory of motion, dynamic range and direction of power action of disks 3 on material contribute to effective bridge breaking. EFFECT: enlarged operating capabilities. 1 dwg
