Распределительное устройство сыпучего материала в пневмотранспортной системе се лки

摘要

FIELD: agricultural engineering. SUBSTANCE: distributing device has case composed of first and second chambers. Feeding pipeline is connected to first chamber and discharge pipelines are connected to second chamber. Turbulizers are fixed on inner surfaces of first chamber. Drop-shaped adjusting gates are fixed in second chamber perpendicular to surface equipped with turbulizers, said adjusting gates being pivotally connected to case. Uniform distribution of bulk material concentration is provided owing to rounded shape of turbulizers having section formed as step defined by concave line at side of feeding pipeline and by vertical straight line at opposite side. Distributing device of such construction may be used in pneumatic conveyance systems for drill and fertilizer spreaders. EFFECT: increased efficiency owing to uniform distribution of bulk material. 3 cl, 4 dwg
