Technical field
The present invention relates to agricultural machinery plant protection equipment technical fields, and in particular to a kind of centrifugal electrostatic atomization nozzle.
Background technology
In modern agriculture plant protection spraying machine tool, plant protection drone static water-spraying system is the main way developed at present,
Static nozzle is plant protection drone static water-spraying system key components and parts.How nozzle and target agriculture that nozzle band on charge be is made
Induction field is formed between crop, it is critical issue to allow the droplet of electrification to be moved to objective crop under the action of electric field force.
In existing plant protection electrostatic spray, make on droplet band there are three types of the major ways of charge：（1）Inductive charging,（2）Corona-type
Charging,（3）Contact charges.Current main static nozzle is hydraulic type circular cone static nozzle, and charging modes are induction types
Charging, this induction type static nozzle spray area is limited, and dosage is extremely difficult to greatly desired control effect very much.Contact
Charging is that the direct liquid with required charging is in direct contact, therefore voltage request is not very high, but security requirement is larger.From
The advantage and spray area of the had ultra low volume spray of core type nozzle are larger, but very high to the requirement of the condition of spraying operation, such as
Fruit wind speed is big, then drift value is very serious.In order to improve the adsorption capacity of centrifugal sprinkler spraying condition, centrifugal electrostatic is developed
Nozzle so that reduce drift value under the action of electrostatic field, adapt to the development of modern Aviation spray technique, to improve agricultural plant protection
The control effect in field plays significant role.
Invention content
To solve the deficiencies in the prior art, the purpose of the present invention is to provide a kind of centrifugal electrostatic atomization nozzles, not only
The ultra low volume spray advantage for meeting centrifugal energy nozzle also enhances the adsorption capacity of centrifugal energy nozzle droplet, and it is quiet to improve plant protection drone
The performance requirement of electrospray system, to make up the deficiencies in the prior art.
The invention is realized in this way：
A kind of centrifugal electrostatic atomization nozzle includes the motor housing of motor and package motor, during the motor housing lower end is
The disc structure of portion's through-hole, motor are installed in the motor housing and are fixed by the lower end of fastening bolt and motor housing, motor
Motor shaft stretched out by through-hole external, the centrifugal atomizing disk of inverted cone-shaped structure is arranged in the underface of motor and the centrifugal atomizing
Disk is sleeved on motor shaft and fixes, and iron ring is arranged on the inner surface of centrifugal atomizing disk, the disk knot in motor housing lower end
3 threaded holes are set on structure, and symmetrically arranged electrode stake is extend by threaded hole in the inner cavity of centrifugal atomizing disk, in two electrodes
Copper ring is welded between stake lower end and copper ring is corresponding with iron ring position, and binding post is set in the upper end of two electrode stakes, is connect equipped with water pipe
The water pipe of head is extend on centrifugal atomizing disk by another threaded hole to realize that liquid is flowed into centrifugal atomizing disk.
Preferably, it is threaded structure in the lower end end of motor shaft, spiro cap realizes centrifugal atomizing disk in motor shaft
Fixes sleeve is arranged to complete the upper and lower position limit to centrifugal atomizing disk in limit on the motor shaft above centrifugal atomizing disk
Position.
By adopting the above-described technical solution, compared with prior art, the present invention leads to metal iron ring and PVC plastic material
The mode for crossing injection molding is joined together to form the centrifugal atomizing disk that can be charged.When water is sent to centrifugal atomizing by water pipe joint
The bottom of disk, the bottom by centrifugal atomizing disk is the iron ring that do not charge, therefore the water of bottom is in centrifugal atomizing disk high-speed rotation
Under when can form water membrane by metal iron ring, can by the electric field between the iron ring on high pressure copper ring and centrifugal atomizing disk
Induction charging, the droplet sprayed in this way have just taken charge, can attract each other with objective crop under the action of electrostatic field.
Generally speaking, charging electrode structure of the invention is simple, reasonable and practical, and cost is not high, is plant protection drone static water-spraying system
A kind of new equipment for plant protection spray pattern is provided in plant protection prevention.
