Abstract
The utility model relates to a novel non-pressure irrigation device. When a water outlet valve gate of a water supply tank is opened, irrigation water flows into a water level control pool. When the water level of the pool exceeds h1, an air inlet pipe is submerged and air inlet is changed into water inlet. Until the water level in the air inlet pipe is equal to that in the water supply tank, the irrigation water stops flowing in the water level control pool and the water level of the pool is stable at a level slightly higher than h1. The irrigation water flows from the bottom of a U-shaped groove of a irrigation machine and enters a filling area at the upper part of a U-shaped groove through a permeable cover plate and a sandstone inverted filter, and a soil saturation water layer which is equal to the water level control pool in terms of water level and lower than the upper edge of the U-shaped grove. Water of the saturation water layer rises to a crop root layer in a manner of capillary water. With the water consumption of crops, the water level in the water level control pool is lower than h1. The air inlet pipe appears outside of a water surface and air flows in in a manner of bubbles. The irrigation water flows in the water level control pool again, and the water level rises to submerge the air inlet pipe again. The utility model is advantageous in that the water consumption of crops causes the water supply process to repeat; the water supply amount increases and reduces with the water consumption amount; a self-adaptive irrigation is achieved; the operation is simple and the use is convenient.

Because supplying water, the present invention adopted law of connected vessels, the head unanimity, and according to Darcy's law, soil saturation water layer height is also consistent, and the water supply uniformity is very high.Even and common infiltrating irrigation has been installed flow regulating equipment additional and also can't have been reached so high water supply uniformity.
The underground plastic delivery hose of common infiltrating irrigation road suffers damaged by rats easily.And groundwater supply device of the present invention, there is the soil saturation water layer on top as barrier, and bottom and side are concrete, and mouse has no interest, and also gnaws motionless.
