The invention has reasonable structure, the technical characteristics thereof are superior to the technical characteristics of the like products at home and abroad, the medicine-mixing concentration uniformity coefficient of variation CV is no more than 10 percent, the fog quantity uniformity coefficient of variation CV is no more than 12 percent, and the target crop deposition rate is above 80 percent.
Description
Technical field:
The present invention relates to a kind of sprayer.
Background technology:
Problems such as the spraying of existing sprayer ubiquity is inhomogeneous, and atomizing effect is undesirable also can't realize cooperating of the flow of spraying and the facility speed of travel, can not avoid the spraying non-uniform phenomenon because of ground out-of-flatness or spray boom vibration generation.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructurely, can effectively realize spraying evenly, the light high-efficiency intelligentized spray rod spraying machine of good working effect.
Technical solution of the present invention is:
A kind of light high-efficiency intelligentized spray rod spraying machine, it is characterized in that: comprise the walking facility, adorn water tank, medicine-chest on the walking facility, water tank, medicine-chest are connected with medicament-mixing device by pipeline, medicament-mixing device is connected with spray boom by pipeline, adorn atomizer on the spray boom, the PWM controller of control medicament-mixing device rate of discharge is set between medicament-mixing device and nozzle, the PWM controller is connected with microcontroller, microcontroller is connected with A/D converter, and A/D converter is connected with the sensor of sensor that obtains facility travel speed signal and acquisition medicine mixer outlet mist flow signal; Spray boom is connected with the piston rod of hydraulic jack, and the level meter that detects the spray boom level is set on spray boom, and level meter is connected with the hydraulic jack controller of control hydraulic jack work.
Described medicine mixer comprises the medicament-mixing device main body, the jet blower that communicates with medicine-chest is set in the main body, the jet blower periphery is a suction chamber, suction chamber is provided with the suction inlet that communicates with water tank, communicate with mixing tube behind the suction chamber, the mixing tube rear end communicates with horn-like anemostat, and the anemostat rear end communicates with spiral organ; Described spiral organ comprises shell, and the spiral unit that mixed liquor is evenly flowed out is set in the shell.
The present invention is rational in infrastructure, have characteristics such as smart quantification, automation, light-duty, efficient, safety, environmental protection, its technical performance is better than similar products at home and abroad, mixes concentration uniformity coefficient of variation CV≤10%, mist amount uniformity coefficient of variation CV≤12%, target crop deposition is more than 85%.
Medicine mixer of the present invention is the quiet mixed form of two-stage self-priming jet.The first order is a self-priming jet level form, the principle of negative pressure of the current that utilize to flow, and in mixed medicine interruption-forming local decompression district, self-priming is from the agricultural chemicals of medicine-chest, thereby plays the effect of current and the preliminary mixing of medicine stream; The second level is static mixer structure, utilizes guide vane that medicine and water are fully mixed, and reaches medicine when going out head piece and water mixes.
The present invention obtains facility travel speed signal by measuring facility driving wheel rotating speed; Obtain medicine mixer outlet mist flow signal by flowmeter.The output signal of facility travel speed signal and mist flow meter links to each other with microcontroller by analog-digital converter (A/D), draws the actual mist amount that arrives on the object.Again actual mist amount is relatively drawn error signal with specifying the mist amount.By the coupling of error signal drives PWM controller realization medicine mixer rate of discharge and facility speed, the present invention need not the GPS assist location, and technology realizes that cost has only 1/20 of external variable farm chemical applying technology; The present invention can guarantee to mix and realize the regulation and control of mist amount under the concentration uniformity prerequisite, and all advantages of medicine mixer are achieved under the condition of mist amount regulation and control.
