The utility model relates to the field of fertilization, especially a circular distribution type fertilization pipeline device, comprising a
water supply assembly, the liquid outlet end of the
water supply assembly is fixedly connected with the liquid inlet end of a plurality of connecting pipes, the liquid outlet end of the connecting
pipe is connected with a bearing box, and the upper end of the bearing box is fixedly connected with a stirring drum, the utility model discloses a centrifugal wheel, a
rotating disc and bristles are arranged, when the mixture of
fertilizer and water flows in the water inlet
pipe, the
water flow drives the centrifugal wheel to rotate, the centrifugal wheel drives the first
bevel gear to rotate through the first rotating rod, the first
bevel gear is engaged with the second
bevel gear, the second rotating rod rotates, the third bevel gear at the other end of the second rotating rod is engaged with the fourth bevel gear, and then the third rotating rod rotates, the
rotating disc fixedly connected with the lower end of the third rotating rod rotates, and the bristles at the lower end of the
rotating disc continuously wipe the inner wall bottom surface of the spray head, the unsolved
fertilizer adhered to the inner wall bottom surface of the spray head is scraped off, the spray head is effectively prevented from being blocked, and the smooth operation of the fertilization process is ensured.
