Patent ID: 10154629

Abstract:
The present disclosure belongs to the technical field of farm irrigation, and particularly relates to a novel pressureless irrigation device. The novel pressureless irrigation device of the present disclosure uniformly conveys irrigation water to crop plant root systems on the basis of a “connector” principle; and the size of a flow cross-section necessarily satisfies the extremely-low flowing speed requirement of “lossless conveyance” for the “connector” in a static pressure dominant operating state, thereby eliminating a problem of irrigator blockage which accompanies energy dissipation. Water enters the atmosphere via transpiration of crop plants, and a water supply water level control pool at a head portion is triggered to replenish the water. The water consumption and water replenishment are adaptive, and human intervention and additional energy are not required, thereby realizing low-cost and “fool-proof” automatic irrigation and true sense of uniform irrigation.
