The invention relates to the related field of
water irrigation. The invention discloses a windproof and soil-
humidity-controllable
spray irrigation device. The device comprises a main box, a syntheticfiber cavity with a downward opening is arranged in the main box; the upper end wall of the
synthetic fiber cavity communicates with a screw rod push plate cavity; a
humidity bevel gear cavity is arranged on the left side of the lead screw push plate cavity; a belt
pulley cavity is arranged on the upper side of the
humidity bevel gear cavity; and the right end wall of the belt
pulley cavity communicates with a tensioning block cavity. The right side of the belt
pulley cavity is provided with a speed regulation gear cavity located on the upper side of the tensioning block cavity. Through a humidity rotary knob and the monitoring of the
soil humidity by synthetic fibers, the quantitative adjustment and control of the soil
irrigation humidity are realized, the
irrigation amount can be randomly adjusted under the different conditions,
irrigation is more reasonable, green plants are protected, and
water resources are further saved. Meanwhile, the size of the
water pressure of an irrigationspray
nozzle is changed through vertical movement of a wind wheel and a friction wheel in the device, so that the influence of wind on
plant irrigation is reduced, and the green plants can still be irrigated smoothly in windy weather.
