Fig. 1 is the automatic fertilizer supplementing device structural representation
Among the figure: 1, base 2, solution 3, solution storage tank 4, solution delivery outlet 5, supplementary fertilizer input pipe 6, supplementary fertilizer mouth 7, supplementary fertilizer valve 8, solution control chamber 9, water inlet 10, water inlet control valve 11, water inlet pipe 12, fertilizer spreading tank 13, flexible material inner bag 14, draining valve 15, fertilizer feeding port 16, solution carrier pipe 17, air bleeding valve 18, irrigation conduit
Embodiment:
Fig. 1 is an embodiment of automatic fertilizer supplementing device of irrigation system of the present invention, comprise a solution storage tank 3 that is provided with in the field, solution storage tank 3 is communicated with a fertilizer spreading tank 12 that is provided with on aqueduct 11, fertilizer spreading tank is provided with supplementary fertilizer mouth 6, water inlet 9, fertilizer feeding port 15, water inlet 9 is provided with in the bottom of fertilizer spreading tank, supplementary fertilizer mouth 6 and fertilizer feeding port 13 are provided with on the top of fertilizer spreading tank, the solution delivery outlet 4 that supplementary fertilizer mouth 6 is provided with supplementary fertilizer input pipe 5 liquid fertilizer storage tanks 3 is connected, supplementary fertilizer input pipe end is provided with supplementary fertilizer valve 7 (selection float-controlled valve), and fertilizer feeding port 15 connects fertilizer carrier pipe 16 and irrigation conduit 18, is provided with into water control valve 10 between water inlet pipe 11 and fertilizer spreading tank water inlet 9.The inner suit one flexible material inner bag 13 of fertilizer spreading tank, supplementary fertilizer mouth 6 and fertilizer feeding port 15 extend in the inner bag, form solution control chamber 8 between fertilizer spreading tank and the inner bag by inlet valve 10 controls, fertilizer spreading tank top also is provided with draining valve 14 and communicates with the solution control chamber, also is provided with air bleeding valve 15 on the fertilizer carrier pipe 16.
The fertilizer feeding port 15 of fertilizer spreading tank setting in the described automatic fertilizer supplementing device of irrigation system is higher than supplementary fertilizer mouth 6.
The concrete application practice of automatic fertilizer supplementing device is: when flexible material inner bag 13 internal pressures reduced, solution was opened float-controlled valve 7 automatically and is realized supplementary fertilizer under action of gravity; When solution adds certain liquid level to, under buoyancy, close automatically and stop supplementary fertilizer.Described float-controlled valve 7 can be other valves with similar effect.And fertilizer spreading tank 12 is regulated by external water inlet pipe 11 and water inlet control valve 10 with the pressure of the middle solution control chamber 8 that forms of flexible material inner bag.
When using first, at first dissolved fertilizer or fertilizer solution are injected in the solution storage tank 3 by charge door; If use solid fertilizer, preferably the dissolving back is poured the solution memory into by filter screen.Under action of gravity, solution 2 is by solution delivery outlet 4, flow to the flexible material inner bag 13 of fertilizer spreading tank 12 through supplementary fertilizer input pipe 5, gas in the solution control chamber 8 is discharged via draining valve 14, when solution is supplemented to the height of supplementary fertilizer mouth 6 in the flexible material inner bag 13, supplementary fertilizer float-controlled valve 7 cuts out automatically, and this moment, flexible material inner bag 13 interior pressure with solution control chamber 8 kept balance.
After the water adding system operate as normal 30 minutes, open into that water control valve 10 makes the water of water inlet pipe 11 enter solution control chamber 8, solution control chamber 8 internal pressures increase gradually, and under pressure, draining valve 14 cuts out automatically.At this moment, flexible material inner bag 13 produces pressure differential with solution control chamber 8, and solution injects irrigation conduit 18 via fertilizer feeding port 15 by solution carrier pipe 16 in the flexible material inner bag 13, realizes fertigation.When flexible material inner bag 13 internal pressures reduced, solution was opened float-controlled valve 7 automatically and is realized a small amount of supplementary fertilizer under action of gravity.In the fertilising process, can also be by water inlet control valve 10, the generation pressure differential of regulating flexible material inner bag 13 and solution control chamber 8 forms suitable fertilising speed.
When each fertilising finishes, close into water control valve 10, pressure in solution carrier pipe 16 and the solution control chamber 8 reduces rapidly, at this moment, the air inlet and exhaust valve 17 that is provided with on the solution carrier pipe 16 effectively prevents siphon, draining valve 14 is designed to the device of valve spring and similar functions, when solution control chamber 8 internal pressures reduce less than valve elastic force apparatus pressure, realizes opening automatically.When the solution volume increased, water was subjected to 13 extruding of flexible material inner bag in the solution control chamber 8, and water level rises, and water is discharged via draining valve 14; When solution was supplemented to the height of supplementary fertilizer mouth 6 in the flexible material inner bag 13, float 7 cut out automatically, and supplementary fertilizer finishes.
Foregoing description only proposes as a kind of enforceable technical scheme of automatic fertilizer supplementing device of the present invention, not as the single restrictive condition to its structure itself.
