Abstract

The present invention provides a water driven quantitative fertilizing device which realizes quantitative fertilization by using irrigation water as a dynamic force under the condition of no additional dynamic force. The present invention is especially suitable for quantitative control of micro irrigation and quantitative control of spray irrigation fertilization. The water driven quantitative fertilizing device is composed of a liquid fertilizer storing tank, a fertilizer transmitting pipeline and a valve, wherein the liquid fertilizer storing tank is installed on an irrigation pipeline. The present invention is characterized in that a group of coaxial hydrodynamic impellers are arranged in front of a junction point between a water transmitting pipeline and the fertilizer transmitting pipeline, and a big impeller is pushed by irrigation water to drive a small impeller to rotate and to pump out the liquid fertilizer. The present invention also designs a pressure compensation type liquid fertilizer storing tank having the functions that the pressure compensation type liquid fertilizer storing tank balances system pressure and ensures that the irrigation water can not flow back to the fertilizing device. The present invention can effectively ensure the balanced output and the quantitative control of the liquid fertilizer, and thereby, the present invention is of great actual significance for realizing precise agricultural metering control; simultaneously, since the present invention does not need an additional dynamic force, both the manufacturing cost and the use cost of the water driven quantitative fertilizing device of the present invention are low, and thereby, the present invention is favorable for popularization and application in rural areas.

Description

Water driven quantitative fertilizer spreader
Technical field
The present invention relates to a kind of quantitative fertilization device that is used to irrigate, is the matching component of slight irrigation, sprinkling irrigation, belongs to agricultural water-saving irrigation mechanized equipment technical field.
Background technology
Along with the popularization and application of water-saving irrigation technique, utilize irrigating facility fertilising or supporting with it fertilizer apparatus also to appear at more and more in the agricultural equipment, routine does not add outer power irrigation has two kinds with fertilizer apparatus, and a kind of is differential, and a kind of is venturi type.Though this dual mode can be injected into solution in the irrigation water in the irrigation process effectively, 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.The venturi type fertilizer apparatus is difficult to hold in the flow velocity and the relation between the solution soakage of irrigation advance during through Venturi throat, can not realize quantitative control.
Summary of the invention
The object of the present invention is to provide a kind of water driven quantitative fertilizer spreader, under the situation of additionaling power not, is that power is realized quantitative fertilization with the irrigation water, is particularly useful for the quantitative control of slight irrigation, sprinkler irrigation fertilization.
Technical scheme of the present invention is achieved in that this water driven quantitative fertilizer spreader, its basic structure is to be made of the liquid fertilizer basin, fertilizer delivering pipe road, the valve that are installed on the irrigation pipeline, and main feature is that described water driven quantitative fertilizer spreader also comprises one group of coaxial hydrodynamic(al) impeller before being arranged at hydraulic pipeline and fertilizer delivering pipe road crosses.
The liquid fertilizer basin of described water driven quantitative fertilizer spreader is communicated with irrigation pipeline, in be provided with the storage fertile elastic internal bladder, fertilizer delivering pipe extend to the storage fertile inner bag the bottom.
The coaxial hydrodynamic(al) impeller of described water driven quantitative fertilizer spreader is placed in two casings, and the upper box import is communicated with the fertilizer delivering pipe road, the lower box import is communicated with irrigation pipeline, and last lower box outlet crosses.
The impeller shaft of described water driven quantitative fertilizer spreader places between the lower box.
The liquid fertilizer basin of described water driven quantitative fertilizer spreader also is provided with dewatering outlet and Draw off valve.
Described water driven quantitative fertilizer spreader and irrigation pipeline adopt and are arranged in parallel, and turnover is all controlled by valve.
The present invention is the liquid fertilizer export technique scheme of power and the pressure balanced design of liquid fertilizer interlayer basin with water owing to having adopted, can guarantee the balanced output of liquid fertilizer effectively, quantitatively control, to realizing that the precision agriculture measure control has big realistic meaning, simultaneously owing to do not need additionaling power, the manufacturing cost and use cost of fertilizer apparatus of the present invention is all lower, helps in the rural area popularization and application.
Description of drawings
Fig. 1 is a fundamental diagram of the present invention
Fig. 2 is that the K of Fig. 1 is to (part) view
Among the figure: 1, pressure compensation jar 2, the fertile inner bag 3 of storage, filling opening 4, fertilizer delivering pipe 5, defeated fertile impeller 6, connecting axle 7, bearing 8, hydrodynamic force impeller 9, liquid manure mixed liquor 10, solution outlet 11, liquid manure mixture export 12, discharging valve 13, dewatering outlet 14, irrigation water 15, irrigation valve 16, irrigation water inlet
Embodiment
The main innovate point of water driven quantitative fertilizer spreader shown in Figure 1 is to be promoted 8 rotations of hydrodynamic force impeller by irrigation water, defeated fertile impeller 5 and the 8 coaxial rotations synchronously that link to each other of hydrodynamic force impeller, big impeller 8 promotes rotation by irrigation water and drives small impeller 5 rotations liquid fertilizer 2 is pumped, and is injected into through liquid fertilizer outlet 10 to form the liquid manure mixed liquor in the irrigation water and be used for irrigating.Liquid fertilizer basin 1 just need not overhead setting or increases complicated control flow apparatus like this.
In order to reach the purpose of quantitative fertilization, the present invention has also designed pressure-compensated liquid fertilizer basin 1, the inner bag 2 of splendid attire liquid fertilizer has been set in basin, basin is communicated with irrigation pipeline, the pressure that inner bag 2 is subjected to is with the change in pressure of irrigation water and equal with it, effect is a balance sysmte pressure, guarantees that irrigation water can not pour in down a chimney to fertilizer apparatus.
Fertilizer apparatus of the present invention can be arranged in parallel on irrigation pipeline, imports and exports by-pass valve control is set, and also is provided with dewatering outlet 13 and valve 12 on the liquid fertilizer basin 1, before inner bag liquid feeding fertilizer with jar in water emit.
