Abstract

The utility model discloses a variable-pressure water supply device for underground drip irrigation. The water supply device comprises pressure tanks, a water pump, pipe dripping heads, a water discharging pipe and a water feeding pipe, wherein dripping holes on each pipe dripping head are upwards arranged under the ground at the root part of a crop, the top part of a first pressure tank is provided with a pressure gauge with electric contacts, the water discharging pipe and the water feeding pipe of the pressure gauge with the electric contacts are respectively provided with an electromagnetic valve, a controller is arranged at one side of each pressure tank, and the controller is connected with a water pump pressure gauge and the two electromagnetic valves respectively through signal cables. In the variable-pressure water supply device for the underground drip irrigation, the dripping pressure is regulated, thereby meeting the water demand of the crop in different growing period; moreover, the utility model has the advantages that the water supply device has a simple structure and is convenient to control without affecting the field operation, etc.

Description

Underground drip irrigation pressure swing type water supply installation
Technical field:
The utility model relates to and watering, and particularly a kind of multitube road that uses is installed in underground underground drip irrigation pressure swing type water supply installation.
Background technology:
The water-saving irrigation technique of underground infiltrating irrigation, at present at home and abroad the water-deficient area use, have broad application prospects.But Kun Rao problem is how many depth of buryings of pipeline be good with always.If buried depth is when plow layer is following, seedling stage, face of land water was not being met, and pipeline buries and hinders farm work when shallow again.The preferred plan that does not also address this problem at present.
Summary of the invention:
The purpose of this utility model provides a kind of needs that can satisfy face of land water in seedling stage, does not hinder the underground drip irrigation pressure swing type water supply installation of farm work again.The technical solution of the utility model is finished as follows, it includes pressurized tank, water pump, pipeline water dropper and downcomer and filler pipe, it is characterized in that: the weeper on each pipeline water dropper upwards is installed in the subsurface of crop root, and an electro connecting pressure gauge is installed at the top of first pressurized tank, on manometric downcomer and filler pipe, be separately installed with a magnetic valve, be provided with a controller that is connected with signal cable with water-aspirator pressure table and two magnetic valves respectively in a side of pressurized tank.This device satisfies the water requirement of crop different growing stages by the regulation and control pressure that drips, have simple in structure, control is convenient, can not influence the advantage of farm work.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail, the utility model is improvements over the prior art.It mainly is the subsurface that weeper on each pipeline water dropper 3 upwards is installed in crop root, and at electro connecting pressure gauge 7 of the top of first pressurized tank 1 installation, on pressurized tank downcomer and filler pipe, be separately installed with a magnetic valve 4 and 6, be provided with a controller 2 that is connected with signal cable 8 with water pump 5 manometers and two magnetic valves respectively in a side of pressurized tank in addition.If when water consumption is bigger, can be in pressurized tank intensified pressure, flow is increased, shorten irrigation period; After crop root forms, supply water by normal pressure and flow, do not need to change the buried degree of depth of pipeline water dropper.Simple in structure, easy to use.
