Specific embodiment
Below in conjunction with Fig. 1, the present invention will be described in detail, and illustrative examples of the invention and explanation are used to explain herein The present invention, but it is not as a limitation of the invention.
A kind of bypass type fertilizer applicator of the adjustable self-adapting pipe flow of EC, PH, including in parallel with main pipeline 18 is irrigated Water inlet line 5 and outlet conduit 17 are parallel with the fertile devices of several suctions between the inlet and outlet pipes, further include fertilizer applicator Controller 9 and the flow sensor 1 on irrigation main pipeline, the fertilising machine controller 9 are felt by receiving flow sensor 1 The main pipeline flow signal and then regulation that should arrive inhale the operating status of fertile device;Irrigation water flows to water inlet pipe through irrigating main pipeline 18 It is inhaled and flows to outlet conduit 17 after fertile device forms rich water mixed liquor, then flowed out through irrigating main pipeline 18 in road 5.It is any one described Inhaling fertile device includes the liquid storing barrel 16 that venturi is inhaled fertilizer 8 and is connected to the venturi fat absorption device, several texts after parallel connection 8 water inlet of fat absorption device is connected to water inlet line 5 in mound, and the water outlet of the venturi fat absorption device is connected to outlet conduit 17, the text The suction fertilizer mouth of fat absorption device is connected to liquid storing barrel 16 in mound.Any one fertile device of the suction further includes being set to the venturi fat absorption device 8 The fertile motor-driven valve 15 of pulse flowmeter 14, control and hand-operated valve 7 between liquid storing barrel 16, the venturi fat absorption device, pulse flow Meter is controlled fertile motor-driven valve, hand-operated valve, liquid storing barrel and is sequentially connected, and the liquid storing barrel can be correspondingly arranged multiple, can be divided into acid solution liquid storage Bucket, aqueous slkali liquid storing barrel etc., the fertile motor-driven valve 15 of the control are controlled by fertilising machine controller 9.It further, further include being set to water outlet Note fertilizer pump on pipeline and the frequency converter with the note fertilizer pump connection, the fertilising machine controller receiving stream quantity sensor sense Place irrigate main pipeline at flow signal, and then by frequency converter regulate and control it is described note fertilizer pump flow and lift.The present invention The flow and lift that note fertilizer pump 11 is adjusted by frequency converter 10 make the fertilizer-injecting flow rate of outlet conduit 17 and irrigate the water of main pipeline 18 Flow is adapted, and guarantees accurately fertilising precision.
It further, further include the pH on-line computing model 12 and/or EC on-line computing model 13 being installed on outlet conduit, institute It states pH on-line computing model and/or EC on-line computing model and passes through the pH value and/or EC of rich water mixed liquor at the outlet conduit of monitoring place Value signal is simultaneously transferred to fertilising machine controller, the pH value that will monitor of fertilising machine controller and/or EC value signal with Default pH value and/or EC value compare, to regulate and control the aperture for inhaling fertile device, make rich water mixed liquor pH value and/or conductance Rate reaches default pH value and/or EC value.The EC on-line computing model 13 and pH on-line computing model 12 that the present invention is arranged, can supervise in real time Survey EC, the pH value of rich water mixed liquor;Flowmeter is installed inhaling fertile device and irrigating on main pipeline, rich water can be set according to demand Then mixed liquid concentration or EC, pH value are controlled by the aperture that flow value signal adjusts the fertile motor-driven valve 15 of control on the fertile device of suction Solution flow value makes rich water mixed liquid concentration or EC, pH value reach required numerical value, easy to operate, easy to use;Moreover, this Invent the EC on-line computing model 13 and pH on-line computing model 12 of setting;Since the concentration of rich water mixed liquor can be monitored at any time, thus The aperture of fertile motor-driven valve is inhaled by fertilising machine controller adjustment, thus to the solution acid alkalinity in liquid storing barrel 16 without particular requirement.
The fertilizer applicator further includes the main motor-driven valve 6 set on water inlet line water inlet, and the main motor-driven valve is by fertilizer applicator Controller 9 controls.When farmland needs fertilizer applicator fertilising, the fertilising machine controller controls main motor-driven valve and keeps centainly Aperture irrigates the irrigation advance of main pipeline to water inlet line, and when not needing fertilizer applicator fertilising, the fertilising machine controller is controlled Main motor-driven valve remains turned-off, and the irrigation water for irrigating main pipeline, which flows directly into, irrigates main pipeline water outlet.The fertilizer applicator can be more Purposes not only can usually play the role of irrigation, moreover, can play the role of fertilising when needing to apply fertilizer.
The fertilizer applicator further includes the one-way cock 4 set on outlet conduit water outlet.The setting of the one-way cock makes The water of outlet conduit can only single flow direction irrigate main pipeline on.
The irrigation main pipeline is additionally provided with the filter 2 that the rich water mixed liquor for flowing out outlet conduit is filtered. The filter can avoid undissolved solid fertilizer and other impurities enter irrigate main pipeline after cause the blocking of irrigation equipment. The irrigation main pipeline is additionally provided with for that will carry out secondary mixed complex fertilizer device through the filtered rich water mixed liquor of the filter 3.The setting of the complex fertilizer device can make rich water mixed liquor mix more evenly.
In implementation process, when needing to apply fertilizer, the main motor-driven valve 6 on water inlet line 5 is opened, and is irrigated in main pipeline 18 Irrigation water enters venturi fat absorption device 8, and the fertilizer in liquid storing barrel 16 is sucked outlet conduit 17, fertilizer applicator by venturi fat absorption device 8 Controller 9 receives the flow signal for irrigating flow sensor 1 on main pipeline 18, is controlled according to the changes in flow rate for irrigating main pipeline 18 The working frequency of frequency converter 10, frequency converter 10 adjust the flow and lift of note fertilizer pump 11, make the solution flow of outlet conduit 17 with The water flow for irrigating main pipeline 18 is adapted, and ensure that accurately fertilising precision, liquid manure mixed liquor is after filter 2 removes impurity It is mixed into the further Quick uniform of complex fertilizer device 3, improves the uniformity of fertilising.
When needing to adjust EC value or pH value, flow sensor 1, pulse flowmeter 14, EC on-line computing model 13, PH are online Monitor 12 transmits information back to fertilising machine controller 9, and the machine controller 9 that applies fertilizer constantly regulate main motor-driven valve 6 according to the data passed back With the aperture for controlling fertile motor-driven valve 15, when the numerical value that EC on-line computing model 13, PH on-line computing model 12 are passed back reaches required numerical value, Main motor-driven valve 6 and the aperture for controlling fertile motor-driven valve 15 remain unchanged, and fertilizer applicator is carried out according to the concentration or ratio with fertilizer always.
