The invention relates to a water-saving
irrigation device with a
water collection function for agricultural production. The water-saving
irrigation device comprises a base, a water pump, a
water pumping pipe, a water conveying
pipe, a platform, an
irrigation mechanism, a water collecting mechanism, a processor and a plurality of supporting columns; the water collecting mechanism comprises a watertank, a draining
pipe and four water collecting assemblies, a fixing plate is arranged in the water tank, and a water collecting hole and a sealing set are arranged at the center of the fixing plate;the irrigation mechanism comprises a connecting pipe, a rotating
assembly and a plurality of irrigation assemblies, and each irrigation
assembly comprises a
sprayer and a spray pipe. According to thewater-saving irrigation device with a
water collection function for agricultural production, rainwater can be automatically collected on rainy days through the water collecting mechanism to be used for irrigation at ordinary times, and thus the
water supply pressure of a
water supply system is reduced; besides, in the irrigation mechanism, the spray pipes and the sprayers can be driven to rotate through the rotating
assembly, the rotation speed of the sprayers can be adjusted, and therefore the position of sprayed water falling on the ground can be changed and the irrigation range can be expanded; uniform irrigation is realized by rotation, and the practicability of the device is improved.
