(designing liquid manure ratio for different crops and fertilizer science).While tank body a adds water, by quantitative fertilizer adding device to
Add an appropriate number of fertilizer (in units of tank body b) in tank body a, plus fertile work should complete before tank body a topped up with water, tank body a
After filling liquid manure, start to carry out drip irrigation to crops.
The operation principle of wherein tank body a drip irrigation is: during use, first tank body a is arranged on a support, and will enter
Water pipe is connected with water system, then is hinged with many arms on shunting disk, and is equipped with multiple water droppers on every arm as quilt
By the crops irrigated, then start water system pressurization water inlet, water with pressure enters Inlet and outlet water combination valve a makes it close, simultaneously
Added water into tank body by water injection pipe a simultaneously plus fertile, the steam vent from top for the air in tank body naturally drains；When in tank body
Liquid manure, close to when filling, closes the water inlet that ball-cock assembly closes water injection pipe a, and makes water system stop supplying water.The then water of water inlet pipe
Pressure disappears, and in the presence of back-moving spring, piston retreats, and radial direction water outlet c opens and outwards supplies liquid manure, starts drip irrigation, tank body a's
After liquid manure sky, then start to intake into fertilizer, so repeatedly, at regular time and quantity accurate drip irrigation can be carried out to crops.
The operation principle of wherein quantitative fertilizer adding device is: during use, fertile pipe will be entered first and be connected with fertilizer system, Ran Houqi
Dynamic fertilizer system enters fertilizer into tank body b, and rich water pressure first passes through sealing barrier film and pushes away check valve core and travel forward, thus closing radially
Water outlet b stops outwards supplying water, simultaneously pressurization rich water pass through radial direction inlet channel b push open water feeding one-way valve and pass through water injection pipe b from
Centre bore enters tank body b, and the steam vent b from top for the air in tank body b naturally drains；Fill when the liquid manure in tank body b is close
When, close float and rise the center inlet opening closing water injection pipe b, fertilizer system will be automatically stopped and supply rich water, then rich water pressure disappears
Lose, under compression spring effect, check valve core retreats, and so that radial direction water outlet b is opened and pours into rich water into tank body a；Until tank body b
Interior rich water is finished, then enters rich water, then fills, and so repeatedly, adds fertile stopping according to setting tank number.
The present invention adopts special quantitative fertilizer adding device to constitute water-fertilizer integral structure with the cooperation of special drip irrigation appliance.This
Invention device itself Non-energy-consumption (only need to control water supply, fertilizer system).Automatically add fertile, drip irrigation, operating cost is low, and structure is tight
Gather, low cost, quantitative plus fertilizer is accurately it is easy to control.Wherein drip irrigation part employs piston sealing structure, has prevented to pass in and out completely
The string water problems of water, good seal performance, stable and reliable in work, service life extends, and piston stroke is big, and water supply fertilizer amount is big, constant voltage
Drip irrigation.Simultaneously because employing floating ball valve structure, tank body a is made to be not subject to water system pressure, low cost of manufacture.Therein fixed
Amount fertilizer adding device, then employ sealing membrane configuration, prevented string water problems, and good seal performance is stable and reliable in work, using the longevity
Life length, equally employs closing Floater Structure, makes tank body b be not subject to fertilizer system pressure, low cost of manufacture.
