Description

A kind of differential fertigation device
Technical field
The utility model relates to a kind of differential fertigation device, is used for the fertigation of farmland water-saving irrigation system, is particularly useful for the preposition pressure regulation of drip irrigation or little spray and filters fertilising, belongs to the agricultural water-saving irrigation equipment technical field.
Background technology
Popularization and application along with water-saving irrigation technique, utilize irrigating facility fertilising or supporting with it fertilizer apparatus also to appear in the agricultural equipment more and more, conventional do not add outer power irrigate with the fertilizer apparatus application maximum be differential fertilizer spreading tank, partly form by fluid reservoir, water inlet pipe, water-supply-pipe and pressure regulator valve etc., and connection is installed on the aqueduct, its operation principle is that 2 on aqueduct form pressure differential, and utilizes this pressure differential with fertilizer, medicament injected system pipeline.The advantage of differential fertilizer spreading tank is that processing and manufacturing is simple, and cost is lower, does not need additionaling power equipment, and the loss of flood peak is little.But also have fertilising concentration and the unmanageable defective of fertilizing amount: differential fertilizer apparatus injects irrigation water when the fertilising process begins fertilizer solution concentration is the highest, carrying out along with the process of irrigation, part irrigation water enters into the liquid fertilizer basin and a jar interior fertilizer solution concentration is reduced, and therefore the concentration of differential fertilizer apparatus solution in whole fertilising process is a variable.Be difficult for to control the flow by fertilizer spreading tank, if pressure reduction is big, then flow of inlet water is big, has easily dashed undissolved fertilizer and causes the obstruction of irrigate band, and little as if pressure reduction, then flow of inlet water is little, can't fully dissolve fertilizer.
Summary of the invention
The utility model provides a kind of improved differential fertigation device, observes flow by fertilizer spreading tank intuitively by spinner flowmeter, thus can by valve accurately control enter the discharge of fertilizer spreading tank and the concentration of fertilizer.
The technical solution of the utility model is achieved in that this differential fertigation device, comprise and connect the fertilizer spreading tank that is arranged on the aqueduct, fertilizer spreading tank is provided with fertilizer injeciton opening, water inlet, fertilizer feeding port, it is characterized in that: described water inlet and fertilizer feeding port are provided with on the top of fertilizer spreading tank, water inlet one end is provided with the aqueduct that extends to the fertilizer spreading tank bottom, the other end connects water inlet pipe and aqueduct, the fertilizer feeding port connection supplies fertile pipe and aqueduct, manages between the pipeline that is connected with water inlet pipe with for fertilizer at aqueduct and is provided with pressure regulating valve.
Described differential fertigation device, described water inlet pipe and and aqueduct between the spinner flowmeter of contacting.
Described differential fertigation device, the bottom of described fertilizer spreading tank is provided with the draining bottom plug.
Described differential fertigation device is provided with the end cap of fertilizer spreading tank on the described fertilizer injeciton opening.
Described differential fertigation device, described water inlet pipe and the water inlet control valve is set and for fertile control valve respectively for the junction of fertile pipe and aqueduct.
The utility model is owing to adopted in water inlet pipe straight cutting fertilizer spreading tank bottom and the technical scheme that spinner flowmeter is installed before water inlet, the water inlet control valve is set and for fertile control valve respectively at water inlet pipe with for the junction of fertile pipe and aqueduct, can intuitively observe flow by fertilizer spreading tank, and then by control valve adjusting flow, the control fertilizer concentration, suitable flow is stablized in formation, has improved the practicality of differential fertilizer spreading tank greatly; Spinner flowmeter is installed on the water inlet pipe, avoided being installed in for fertile pipe and gone up the growth of the algae that the mixed liquor owing to fertilizer and water forms and the covering of color, guaranteed the visible and accurate of spinner flowmeter reading, can guarantee the balanced output of liquid fertilizer effectively, to realizing that the precision agriculture measure control has big realistic meaning, owing to do not need additionaling power, manufacturing cost and use cost of the present utility model is all lower, helps in the rural area popularization and application simultaneously.
Description of drawings:
Fig. 1 is the structural representation of differential fertigation device
Among the figure: 1, fertilizer spreading tank 2, spinner flowmeter 3, water inlet pipe 4, for fertile pipe 5, draining bottom plug 6, water inlet control valve 7, for fertile control valve 8, aqueduct 9, pressure regulating valve 10 aqueducts 11, fertilizer feeding port 12, fertilizer injeciton opening 13, fertilizer feeding port 14, solution
Embodiment:
Fig. 1 is an embodiment of the differential fertigation device of the utility model, comprise and connect the fertilizer spreading tank 1 that is arranged on the auxilliary waterpipe 8, fertilizer spreading tank is provided with fertilizer injeciton opening 12, water inlet 11, fertilizer feeding port 13, water inlet 11 and fertilizer feeding port 13 are provided with on the top of fertilizer spreading tank, main design philosophy is that water inlet 11 1 ends at fertilizer spreading tank are provided with the aqueduct 10 that extends to the fertilizer spreading tank bottom among the figure, the other end connects water inlet pipe 3 and aqueduct 8, fertilizer feeding port 13 connections supply fertile pipe 4 and aqueduct 8, manage between the pipeline that is connected with water inlet pipe with for fertilizer at aqueduct 8 and are provided with pressure regulating valve 9; The upright glass rotameter 2 of installing can be made support and place flowmeter between water inlet pipe 3 and the aqueduct (8).
Fig. 1 has also illustrated water inlet pipe 3 and for the installation site of fertile pipe 4 on the fertilizer spreading tank tank body, and fertilizer injeciton opening 12 is provided with the position of the end cap of fertilizer spreading tank, and the bottom of fertilizer spreading tank is provided with draining bottom plug 5.Water inlet pipe 3 and water inlet control valve 6 is set and for fertile control valve 7 respectively for the junction of fertile pipe 4 and aqueduct 8.
When using the utility model fertilising, at first dissolved fertilizer or fertilizer solution are injected in the fertilizer spreading tank 1 the sealing cover by charge door; If use solid fertilizer, preferably the dissolving back is poured fertilizer spreading tank into by filter screen.After the water adding system operate as normal 30 minutes, open control valve 7 and make for fertile pipe 4 connections, open control valve 6 again and connect water inlet pipes 3, at this moment, the pressure of fertilizer spreading tank and aqueduct keeps balance.Then, turn down pressure regulator valve 9, produce pressure reduction in the aqueduct before and after the valve, water enters fertilizer spreading tank by water inlet pipe 3, the spinner flowmeter of installing on the water inlet pipe 2 shows the flow that passes through, regulate by water inlet pipe 3 with for the control valve 6,7 on the fertile pipe 4 again, forms suitable stable flow, enter behind the aqueduct 8 and to enter soil with irrigation water and be made for thing and absorb by fertilizer spreading tank 1.After fertilising finishes, continue to irrigate more than 20 minutes with flushing pipe.
The advantage of embodiment of the present utility model is simple in structure, and manufacturing cost reduces significantly, is suitable for applying at the rural area green house.
Foregoing description only proposes as a kind of enforceable technical scheme of the differential fertigation device of the utility model, not as the single restrictive condition to its structure itself.
