The water inlet is provided with a limiting part capable of blocking the ball body, and the limiting part is a net arranged on the lower end face and used for preventing the ball body from being separated from the fertilizer dissolving barrel into which the water inlet enters.

The fertilizer outlet is provided with a microporous filter, and fertilizers which are not dissolved in the fertilizer dissolving barrel can be left in the fertilizer dissolving barrel.

Through the utility model discloses a gaseous fertile integrative device of fertilization that dissolves of venturi type can be irrigated for crops with air and water and fertilizer dissolve together to provide necessary air and nutrient of growth for crops.

Detailed Description

In order to explain the technical solution more clearly, the following embodiments are used to further explain the present invention:

the utility model discloses a venturi type gas dissolves fertile fertilization integrated device, include water storage tank 1, force (forcing) pump 2, venturi 3 and dissolve fertile bucket 4 that communicate in proper order through the conduit, force (forcing) pump 2 is used for adjusting the liquid pressure in the pipeline, venturi 3 includes inflow 31, throat 33, outflow 32, is provided with an inlet tube 34 in the throat; the fertilizer dissolving barrel comprises a water inlet 8, a fertilizer inlet 7 and a fertilizer outlet 6.

Adopt above-mentioned structure, the utility model discloses a force (forcing) pump 2 is connected with venturi 3 and provides stable pressure to venturi 3, uses liquid to enter into throat 33 through inflow portion 31 when, because the pipe diameter reduces and leads to the velocity of liquid flow grow throat 33 is owing to be provided with introducing tube 34, and the velocity of liquid flow of throat 33 leads to the pressure in the introducing tube to be less than atmospheric pressure greatly, produces the pressure differential, and outside gas can enter into throat 33 and liquid through introducing tube 34 and dissolve and enter into and dissolve fertile bucket 4 in the liquid flow process, and dissolve the fertilizer in fertile bucket 4 and merge, carry mixed solution in to drip irrigation system through play fertile mouthful 6, through the utility model discloses a gaseous integrative device of fertilizer application that dissolves of venturi realizes the process that liquid, gas and fertilizer merge.
