specific Embodiment approach

[0042] Close the valve two 18-1, open the sealing cover 11-1 and valve one 7-2, fill up the negative pressure water tank 11 with water, cover the sealing cover 11-1, and tighten the valve -7-2, under the capillary force in the soil, absorb water from the water seepage device 14 to the soil, so that negative pressure is generated in the system, under the action of negative pressure, the water in the float water tank 1 moves along the connecting pipe -6 Enter the pressure regulating pipe 7 to realize continuous water supply.

[0043] When the pressure in the negative pressure irrigation system is balanced, the negative pressure in the pressure regulating pipe 7 is constant (related to the height of the connecting pipe 6), and the system can be adjusted by adjusting the water level in the pressure regulating pipe 7. When the internal pressure is balanced, the soil suction required for the seepage at the water infiltrator is used to adjust the soil moisture content. Raise the wat...

Abstract

The invention relates to a negative pressure irrigation system. The system comprises a floater water tank, a pressure adjusting pipe, a negative pressure water tank, a water seepage pipe and a water seepage device arranged on the water seepage pipe, the floater water tank is connected with the upper portion of the pressure adjusting pipe through a first connection pipe, and the lower portion of the pressure adjusting pipe is connected with the upper portion of the negative pressure water tank through a second connection pipe; the bottom of the negative pressure water tank is connected with thewater seepage pipe horizontally laid through a water conveying pipe, and a pigging device is arranged on the water seepage pipe; an air suction device is arranged at the top of the pressure adjustingpipe, a first valve is arranged on the air suction pipe, and a sponge with the inner diameter matched with that of the pressure adjusting pipe is arranged in the pressure adjusting pipe; a water addition port is formed in the top of the negative pressure water tank, and a sealing cover is arranged at the water addition port; a throttle valve is arranged on the first connection pipe, and a first one-way valve is arrange on the second connection pipe. The provided negative pressure irrigation system is flexible in negative pressure adjustment, can avoid the situation that the water seepage pipeis blocked, and generation of air bubbles in the system is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of crop irrigation, in particular to a negative pressure irrigation system. Background technique [0002] At present, advanced agricultural water-saving irrigation technologies include sprinkler irrigation and micro-irrigation. The use of sprinkler irrigation is affected by meteorological conditions. In the arid and semi-arid areas of northern my country where the wind is strong, the evaporation and drift loss of water during the sprinkler irrigation process greatly reduces the water-saving effect of sprinkler irrigation. In addition, sprinkler irrigation requires greater pressure. High requirements, difficult to implement in some areas. The micro-irrigation system uses special equipment to turn the pressurized water flow into small water flow or water droplets, moistens the soil near the root layer of the crop, and has an ideal water-saving effect. And dripper and other parts, the equipment input price is ...
