Abstract

A drop irrigation device consists of a water storage tank, a water inlet pipe, a float valve, a throttle valve and a water outlet pipe. The water inlet pipe and the throttle valve are communicated with the water storage tank, and the water outlet pipe is communicated with the throttle valve. The throttle valve is provided with maze type capillary pore whose one end opening is communicated with the water storage tank, while the other end opening is communicated with the water outlet pipe. The utility model can gradually drip water to the root of the plant at interval and in quantities; thus the weed is restricted from growing in the drought area; the labor intensity is greatly lessened, the irrigation semi-automation is realized and the water source is greatly saved. Meanwhile, the water will not spray on the pistil of the plant to affect the crop.

Description

Dripping irrigation device

The utility model belongs to farm machinery, relates in particular to a kind of Dripping irrigation device.

The irrigation method that traditional farming is commonly used mainly contains flood irrigation, pouring, sprinkling irrigation.Flood irrigation is the formula orchard, land for growing field crops that utilizes irrigation canals and ditches that the water guiding need be watered, and easily forms underground leakage, surface evaporation, and the availability of water resource is low, and waste is big.Pouring is to utilize manpower to carry on the shoulder and in one's hands water is spilt to crop, and labour intensity is big, time-consuming consumption power, and production efficiency is low.Sprinkling irrigation is to utilize high-pressure spray and guide vane rotary nozzle, and jet is spilt on the crop in the certain radius scope, can realize mechanized operation, thereby greatly improve working condition, has improved production efficiency, than preceding two kinds of methods very big progress has been arranged; Because single shower nozzle can only cover the garden area in the certain radius, on the land for growing field crops, then need overlapping covering, it is inhomogeneous to water, and its surface evaporation loss is inevitable.And some crop full-bloom stages needs water and on the bud that do not allow to spray water.

The purpose of this utility model is exactly in order to address the above problem, and a kind of Dripping irrigation device is provided.

A kind of Dripping irrigation device is characterized in that being made up of storage tank, water inlet pipe, float-controlled valve, choke valve and outlet pipe, and water inlet pipe, choke valve communicate with storage tank, and outlet pipe communicates with choke valve.

The capillary that labyrinth-like is arranged on the choke valve, an end opening capillaceous communicates with storage tank, and other end opening capillaceous communicates with outlet pipe.

The water inlet of water inlet pipe is equipped with filter.

The delivery port of outlet pipe is connected in series mutually with some choke valves, and the capillary of labyrinth-like is arranged on the choke valve, and an end opening capillaceous communicates with outlet pipe, the direct water outlet of other end opening capillaceous.

The utility model can directly splash into water the root of crop at regular time and quantity at leisure according to the needs of crop different growing stages, also can suppress the growth of weeds indirectly in the arid area.Avoided unnecessary underground leakage and surface evaporation waste fully; People only fibrous root according to needs in time switch water supply main valve get final product, be well suited for the scale management management, greatly subtracted labour intensity, realize the semi-automation of irrigation, greatly saved water resource, make limited water resource give play to bigger economic benefit: because of its required head is equally low with flood irrigation, thereby to save the required supercharging equipment of spraying, saved electric energy.Simultaneously can not influence harvest because of water is spread across on the pistil of crop yet.

Fig. 2 is the B of Fig. 1---the B cutaway view:

Fig. 3 is the A of Fig. 2---A revolved section enlarged drawing;

Fig. 4 is the sectional view that the utility model choke valve is connected in series mutually;

Describe in detail below in conjunction with accompanying drawing.The 1st, storage tank, the 2nd, water inlet pipe, the 3rd, draining valve, the 4th, float-controlled valve, the 5th, choke valve, the 6th, outlet pipe, the 7th, filter, the 8th, the capillary of labyrinth-like.

The capillary that labyrinth-like is arranged on the choke valve, an end opening capillaceous communicates with storage tank, and other end opening capillaceous communicates with outlet pipe.Damping and the conducting to the current that utilize capillary to have are used for controlling water velocity, and under certain liquid level, the tube gap degree that changes caliber capillaceous or material is the flow of controlled choke valve then.Make material capillaceous and comprise that braid, nonwoven, sintered fiber etc. have capillary material and have chemosmotic film class (as reverse osmosis membrane).

As shown in Figure 4, the delivery port of outlet pipe is connected in series mutually with some choke valves, and the capillary of labyrinth-like is arranged on the choke valve, and an end opening capillaceous communicates with outlet pipe, the direct water outlet of other end opening capillaceous.

The water inlet of water inlet pipe is equipped with filter.Filter should be able to filtering than capilar bore in the choke valve through big impurity, avoid stopping up capillary.

Float-controlled valve is the water level that is used for adjusting and control in the storage tank, thus the speed of control outlet pipe water outlet (or claiming flow).

In order to use the utility model in the north, on storage tank, also draining valve can be installed, avoid producing icing spalling.

Also can increase the chemical fertilizer dissolver as required, be crop fertilization.
