The invention discloses a double-part support rotary micro-sprinkler. The double-part support rotary micro-sprinkler comprises a support, a rotary body and a
nozzle, wherein the support is a double-part support, a positioning hole is formed in the upper end of the support, and a sleeve is arranged at the lower end of the support; the rotary body comprises a water inlet hole, a
water diversion baffle, runners and a rotary shaft which are designed in sequence from bottom to top; and the runners include the first runner and the second runner, the elevation of the first runner is larger than that of the second runner, the first runner and the second runner each have an
deflection angle, and the
deflection angle of the first runner is smaller than that of the second runner. The double-part support rotary micro-sprinkler has the advantages that the sprinkling
radius is large, sprinkling is uniform, and the effect that in a certain
pressure range, support deformation caused by
high pressure does not occur, and rotation of the rotary body is not affected is achieved; the micro-sprinkler is convenient and fast to
mount and dismount; due to large sprinkling width, the number of sprinklers adopted per mu on average is small, and first-time
investment cost of micro-
irrigation projects is reduced; and sprinkling is uniform in the sprinkling width direction, so that
moisture and nutrients obtained by crops are uniform, the growing vigor is uniform, and high-yield and high-quality agricultural products can be easily achieved.
