A kind of water-fertilizer integral fertilizer applicator
Technical field
This utility model relates to a kind of agricultural production equipment, particularly a kind of fertilizer applicator.
Background technology
Water-fertilizer integral Precision Irrigation fertilizer practice is precision agriculture new technique fertilising combined with irrigation, it is by irrigation system, the solution dissolved by solid fertilizer or liquid fertilizer the most uniformly, is accurately input to crop root soil, effectively control duty and dose, improve liquid manure utilization ratio.Realizing water-fertilizer integral Precision Irrigation fertilizer practice and need corresponding water supply, fertilizer, the most precisely facility such as fertigation, irrigation pipe network, its key core device is automatic fertilizer applicator the most accurately.Fertilizer applicator can program at the scene or the controller of external weather station controls, and by monitoring EC(electrical conductivity in real time)/PH(acid-base value) value, fertilizer injector exactly fertilizer nutrient is injected and irrigate in supervisor's net, perform accurate fertigation.In the prior art, water-fertilizer integral fertilizer applicator is the amount using the high frequency mo (break-make) of high frequency battery valve to control to flow into fertilizer, the amount the most on the contrary sucking fertilizer is interrupted rather than constant, lasting, can cause in rear end complex fertilizer uneven, causes rich water control accuracy to be forbidden.It addition, when fertilizer dissolves not thorough, fertiliser granulates can block high-frequency electromagnetic valve, to such an extent as to high-frequency electromagnetic valve can not completely be closed, and causes the uncontrollable of fertilizer-sucting quantity.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of water-fertilizer integral fertilizer applicator, makes rich water mix evenly, it is achieved being precisely controlled of rich water supply.
In order to solve above-mentioned technical problem, a kind of water-fertilizer integral fertilizer applicator of the present utility model, including frame, primary input water pipe it is provided with in frame, the Heavenly Stems and Earthly Branches are had to input water pipe if described primary input water pipe connects, the outfan of this input water pipe is connected to Development of Venturi Fertilizer Applicator, the fertilizer input of described Development of Venturi Fertilizer Applicator is connected with peristaltic pump and first flow sensor in turn, this first flow sensor is connected with fertilizer source by fertilizer pipe, the outfan of described Development of Venturi Fertilizer Applicator is connected to main output water pipe, and this main output water pipe is provided with driving pump.
PH value sensor and EC value sensor it is separately installed with on described main output water pipe.
On described main output water pipe, second flow sensor is installed.
On described main output water pipe, filter is installed.
Described primary input water pipe top is provided with gas bleeder valve.
It is connected between fertilizer input and the peristaltic pump of described Development of Venturi Fertilizer Applicator and has the first ball valve.
It is connected between described first flow sensor and fertilizer pipe and has the second ball valve.
The beneficial effects of the utility model are: use peristaltic pump to control the supply of rich water mixed liquor in this water-fertilizer integral fertilizer applicator, the rotating speed of peristaltic pump is adjustable, can be according to setting flow supply fertilizer, contact pump line does not contact the pump housing, can prevent fertiliser granulates from resulting in blockage, and makes rich water mix evenly, being precisely controlled of rich water supply can be realized, and there is good suction capacity, idle running also prevents rich water mixed-liquor return, it is simple to safeguard.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is one of structural representation of the present utility model;
Fig. 2 is the two of structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, a kind of water-fertilizer integral fertilizer applicator of the present utility model, including frame 1, primary input water pipe 2 it is provided with in frame 1, the Heavenly Stems and Earthly Branches are had to input water pipe 3 if described primary input water pipe 2 connects, the outfan of this input water pipe 3 is connected to Development of Venturi Fertilizer Applicator 4, the fertilizer input 41 of described Development of Venturi Fertilizer Applicator 4 is connected with peristaltic pump 5 and first flow sensor 6 in turn, this first flow sensor 6 is connected with fertilizer source by fertilizer pipe 7, the outfan of described Development of Venturi Fertilizer Applicator 4 is connected to main output water pipe 8, driving pump 9 is installed on this main output water pipe 8.This water-fertilizer integral fertilizer applicator use peristaltic pump control the supply of rich water mixed liquor, the rotating speed of peristaltic pump is adjustable, can be according to setting flow supply fertilizer, contact pump line does not contact the pump housing, can prevent fertiliser granulates from resulting in blockage, and makes rich water mix evenly, being precisely controlled of rich water supply can be realized, and there is good suction capacity, idle running also prevents rich water mixed-liquor return, it is simple to safeguard.
Wherein, described main output water pipe 8 is separately installed with pH value sensor 10 and EC value sensor 11, can be to the pH value of rich water mixed liquor and the monitoring in real time of EC value.On described main output water pipe 8, second flow sensor 12 is installed, in order to be monitored controlling to the output of rich water mixed liquor.On described main output water pipe 8, filter 13 is installed, to filter large-particle fertilizer in rich water mixed liquor.
Described primary input water pipe 2 top is provided with gas bleeder valve 14, makes the gas in primary input water pipe to discharge in time.Being connected between the fertilizer input 41 of described Development of Venturi Fertilizer Applicator 4 and peristaltic pump 5 and have the first ball valve 15, be connected and have the second ball valve 16 between described first flow sensor 6 and fertilizer pipe 7, wait when needed and fertilizer can be inputted manual operation, the suitability is higher.
The foregoing is only preferred embodiments of the present utility model, as long as realizing within the technical scheme of this utility model purpose broadly falls into protection domain of the present utility model with essentially identical means.
