A drainage and irrigation device suitable for crop water resource utilization

Abstract

The invention discloses a drainage and irrigation device suitable for water resource utilization of crops, which comprises a nozzle and a network structure hidden pipe, both of which are buried in the soil layer. The water inlet, the first sliding chamber, the second sliding chamber and the soil protection groove, the water inlet pipe is connected with the water supply pipe, and the inner pipe is arranged in the outer casing, and the inner pipe is the diversion chamber, the lifting pipe and the soil protection plate from bottom to top, and the guide The upper part of the flow cavity is contracted, and the contracted part of the upper end of the flow guide cavity is covered with a spring, and the inner side of the flow guide cavity is provided with turbine blades, and the middle part of the side of the lift tube is provided with a second water outlet, and the side of the lift tube is evenly distributed near the side of the soil plate There is a third water outlet; the invention adjusts the impact of the water flow on the turbine blades by controlling the pressure of the water flow, so as to realize the lifting of the inner pipe, and realize the two modes of infiltration irrigation and spraying of the green land through the lifting of the inner pipe.

Description

technical field [0001] The invention relates to the technical field of water irrigation, in particular to a drainage irrigation device suitable for utilizing water resources of crops. Background technique [0002] Irrigation technology has developed rapidly in production and life, and its sprinkler irrigation technology is the most widely used, especially on urban green land. Sprinkler irrigation uses nozzles to spray water directly onto the green land. In hot summer, due to the high temperature, When spraying water, it can have a cooling effect, especially suitable for high temperature periods such as noon, but the water sprayed on the green ground will be evaporated quickly, which is not conducive to the absorption of water by green ground water plants, resulting in a waste of water resources. The nozzles for sprinkler irrigation are set above the ground, which seriously affects the pruning of green plants, especially the sprinklers set on both sides of the road. Because o...

[0002] Irrigation technology has developed rapidly in production and life, and its sprinkler irrigation technology is the most widely used, especially on urban green land. Sprinkler irrigation uses nozzles to spray water directly onto the green land. In hot summer, due to the high temperature, When spraying water, it can have a cooling effect, especially suitable for high temperature periods such as noon, but the water sprayed on the green ground will be evaporated quickly, which is not conducive to the absorption of water by green ground water plants, resulting in a waste of water resources. The nozzles for sprinkler irrigation are set above the ground, which seriously affects the pruning of green plants, especially the sprinklers set on both sides of the road. Because of the protrusion and the bottom surface, they often trip pedestrians and cause pedestrians to be injured. In addition, in order to make green plants It is necessary to fully absorb water and reduce the waste of water resources. It is necessary to bury the irrigation water pipes in the ground and use the infiltration of water in the soil to irrigate directly below the surface. Therefore, the present invention provides a spray pipe that can simultaneously A sprinkler head capable of subterranean infiltration irrigation, which solves the above-mentioned technical problems
