VIBRATION TRANSPORTATION DEVICE Russian patent published in 2001 - IPC

FIELD: lift-and-transport engineering; vibration transportation of loose materials, construction and chemical materials. SUBSTANCE: proposed device has horizontal base coupled with low-frequency harmonic vibration exciter in transportation plane. It has also guide longitudinal round-section beam installed in direction of transportation on two vertical supports, and load-carrying member. Load-carrying member is made in form of bushing fitted on beam for free displacement lengthwise the beam and furnished with load-carrying container secured in middle part of bushing from outside. Rectangular recesses are made at both edges of bushing on its inner surface and in one diametric plane with load-carrying container. These recesses are arranged opposite to each other in pairs. Friction blocks in form of curvilinear plates are freely fitted in recesses. Radius of curvature of curvilinear plates corresponds to radius of cross-section of longitudinal beam. Friction block can displace radially relative to beam and can be fixed in required positions. EFFECT: reduced power losses. 2 dwg
