Electrostatic spraying device and method thereof

Abstract

The invention provides an electrostatic spraying device and a method thereof, and belongs to the field of agriculture assembly. According to the method, water and original liquid pesticide are stored in a separated mode, the flow of the liquid pesticide is changed through a frequency conversion motor so as to achieve needed concentration of the liquid pesticide, meanwhile, before mixing, the water is charged so as to mix the water and the original liquid pesticide more evenly to achieve electrostatic spraying at the same time, and the evenness of sprayed drips is improved. The method is convenient and reliable to implement, and the electrostatic spraying device is easy to overhaul, suitable for fieldwork and capable of improving the prevention and treatment effect.

Description

technical field [0001] The invention belongs to the field of agricultural equipment, in particular to an electrostatic spraying device and a method thereof. Background technique [0002] Plant protection is a very important link in agricultural production, which affects the healthy growth of crops. Plant protection methods include chemical control, physical control and biological control. Because chemical control has the characteristics of high work efficiency and timely control, it can control sudden and large-scale outbreaks of diseases and insect pests in time, so it is still the most widely used field plant protection method at present. The realization of chemical control requires plant protection spray system, usually The field plant protection spray system consists of a medicine box, pump, valve, pressure gauge, spray rod, nozzle and hose. When performing field operations, it is necessary to prepare a certain concentration of liquid medicine in proportion in advance, ...

Because chemical control has the characteristics of high work efficiency and timely control, it can control sudden and large-scale outbreaks of diseases and insect pests in time, so it is still the most widely used field plant protection method at present. The realization of chemical control requires plant protection spray system, usually The field plant protection spray system consists of a medicine box, pump, valve, pressure gauge, spray rod, nozzle and hose. When performing field operations, it is necessary to prepare a certain concentration of liquid medicine in proportion in advance, and then transport it to the field for spraying operations. Because The sprayer filled with chemical solution travels on rough roads for a long time, its life is greatly reduced, and it takes a lot of time to add chemical solution back and forth, because it seriously reduces the efficiency of plant protection operations and increases the work intensity of operators and sprayers

[0003] At present, there are some devices that realize on-line drug mixing. Chinese patent CN200810027898 discloses a drug mixing device. This device considers that the spray concentration can be changed in real time, and one or more drugs are sprayed separately or at the same time. The method of medicine has great damage to the equipment, and the uniformity of the mixed medicine is not considered; Chinese patent CN201310194432 discloses a variable spray device for automatic medicine mixing, which uses an automatic medicine suction mixer very well, but this kind of medicine mixing In practical application, the water inlet pressure vacuum is not enough, the water inlet pressure is greatly affected by the return water volume, and the drug absorption ratio is unstable; Chinese patent CN201410210118.7 discloses a real-time mixed drug type variable spray device and method. The jet stirring and mixing module and the ultrasonic fruit tree profiling module are added. In practice, the jet stirring and mixing module also has insufficient water pressure and vacuum, and the drug absorption ratio is unstable, and the device and method are highly targeted. Not suitable for field work
