Abstract

The invention discloses an equipotential head suspension micropressure drip irrigation equipment, comprising a main tube, a branch tube, a hair canal, a suspension micro path emitter, a water tank and a main tube water pressure regulating mechanism. The main tube water pressure regulating mechanism comprises a water regulating tank and a constant water level tank. A one-way inlet valve is arranged between the water regulating tank and the constant water level tank. A water supply tank is arranged in the water regulating tank. The water tank is set at the upper end of the water regulating tank and connected with the water regulating tank by a water supply switch to make the water level of the constant water level tank constant. The water outlet of the constant water level tank is connected with the water inlet of the main tube. The water inlet of the hair canal is connected with the water outlet of the branch tube. The hair canal is hung with hoses with different length in the perpendicular direction. The micro path emitter is arranged on the hose. Compared with the prior art, the device has simple structure, low cost, energy-saving, convenient application and maintenance, constant outflow of the micro path emitters, good irrigation effect and is suitable for applying in wide countryside.

Description

technical field [0001] The present invention aims at the low irrigation uniformity and poor irrigation effect of current micro-pressure drip irrigation irrigators, and designs a micro-pressure drip irrigation device with equal water head suspension. The device of the present invention can implement automatic and uniform irrigation. It belongs to the technical field of agricultural water-saving irrigation. Background technique [0002] Existing micro-pressure drip irrigation technology mainly consists of three parts: namely water supply, pipeline and sprinkler. In the design of water supply power, it mainly relies on the water pump to provide continuous and stable pressure. In the design of pipeline network, the pipeline design of circular pipe network, tree pipe network and ring tree is generally adopted. Drip irrigation is implemented under micro-pressure, and the head loss caused by the movement of water flow directly affects the uniformity of irrigation and determines t...
