HYDRAULIC FEEDER FOR SPRINKLING MACHINE Russian patent published in 1999 - IPC

FIELD: agricultural engineering, in particular, equipment for preparing mineral fertilizer solution and supplying mother liquor to water pipelines of sprinkling machine. SUBSTANCE: hydraulic feeder has pull-type fertilizer hopper, conveyor driven from carrier wheel, dosing shutter, mixing chamber positioned at rod conveyor outlet end, water main pipeline and pipeline for supplying working fluid upon mixing with mother liquor, which are connected to suction and pressure systems of sprinkling machine pump. Hydraulic feeder is coupled to sprinkling machine through mechanism for displacement of pull-type fertilizer hopper. Mixing chamber is provided with fertilizer, mother liquor and working fluid flow dividers. Mother liquor and working fluid flow divider is formed as conical feeding funnel with mother liquor activator positioned under funnel. Mother liquor activator has rigidly fixed blades, each formed as thin disk and positioned in slots of upper and lower flat rings. Upper ring is joined with conical feeding funnel. Disks are fixed in rings by thrusts. Blades are biased from radial position to opposite side relative to nozzle for supplying water streams into cavity between mixing chamber and conical feeding funnel. Nozzle is hydraulically communicated via T-piece to inclined water supplying main pipeline and mother liquor mixer valve. Mother liquor mixer is mounted in inclined position on mixing chamber bottom. EFFECT: increased efficiency by uniform distribution of mineral fertilizers, increased crop yield by intensified mineral fertilizer solving process and removal of slime from mixing chamber. 25 cl, 9 dwg
