Quick-release electrostatic centrifugal shower head

Abstract

The application belongs to the technical field of electrostatic spraying of plant protection aviation, and particularly relates to a quick-release electrostatic centrifugal nozzle. The quick-release centrifugal nozzle is powered by an integrated motor, and the motor power output end drives the quick-release centrifugal rotating disc to rotate. The integrated motor power output end and the quick-release centrifugal rotating disc are connected through a quick-release structure, and a spring is arranged between the concave hole and the convex block. When the quick-release centrifugal rotating disc needs to be replaced, the quick-release centrifugal rotating disc is pushed inward, and the spring is compressed. Since the convex block of the quick-release centrifugal rotating disc is an arc-shaped structure with a narrow front and a wide rear, the quick-release centrifugal rotating disc is rotated to an angle without the concave hole of the motor output end, and then the quick-release centrifugal rotating disc can be quickly pulled out. The convex block of the quick-release centrifugal rotating disc of another structure is inserted into the concave hole of the motor output end, and the replacement of the quick-release centrifugal rotating disc is completed.

Description

Technical Field

[0001] This invention belongs to the field of agricultural aviation electrostatic spraying technology, specifically a quick-release electrostatic centrifugal nozzle. Background Technology

[0002] Plant protection spraying is a primary method for preventing agricultural pests and diseases. Spraying effectiveness impacts pesticide utilization, crop yield, and environmental safety. In recent years, aerial centrifugal nozzles have become increasingly widely used in aerial spraying, such as in agricultural drone operations. However, significant droplet drift during aerial spraying leads to lower pesticide utilization. Electrostatic spraying is a highly effective method for improving spraying quality, significantly increasing pesticide droplet deposition. However, combining electrostatic spraying with aerial plant protection presents a challenge. Specifically, for centrifugal nozzles with high-speed rotating structures, connecting the rotating structure to a power source and ensuring effective droplet charging is a technical problem that needs to be solved. Furthermore, the optimal biocontrol particle size varies for different crops. In other words, different growth stages and crop types require different particle sizes to achieve better pesticide application results. Different particle sizes also affect droplet concentration. Centrifugal discs with different shapes and structures can produce particles of different sizes. How to quickly and easily change the disc structure affects the efficiency of plant protection spraying operations and the effect of pesticide spraying. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention proposes a quick-release electrostatic centrifugal nozzle; it combines electrostatic spraying technology with aerospace plant protection centrifugal nozzles, and enables rapid and convenient adjustment of particle size for different crops.

[0004] The present invention achieves the above-mentioned technical objectives through the following means.

[0005] A quick-release electrostatic centrifugal nozzle is characterized by comprising an integrated motor, an electrostatic sleeve, a quick-release centrifugal disc, and an inlet pipe.

[0006] The motor output end of the integrated motor has a recessed hole, which can be quickly plugged in and unplugged to cooperate with the protrusion on the quick-release centrifugal turntable. The connection between the protrusion and the recessed hole is reinforced with a spring for vibration reduction. The quick-release structure formed by the protrusion and the recessed hole can quickly replace centrifugal turntables with different structures to adapt to different particle size requirements.

[0007] The recessed hole at the output end of the integrated motor is rectangular, with a width of not less than 3mm and not more than 5mm.

[0008] The integrated motor has a wire hole inside, with a width of not less than 4mm and not more than 10mm. The distance between the outermost edge of the wire hole and the outer edge of the integrated motor depends on the material of the nozzle. For example, when the housing material of the integrated motor is polytetrafluoroethylene, the distance between the outermost edge of the wire hole and the outer edge of the integrated motor is 3-4mm; when the housing material of the integrated motor is iron, the distance between the outermost edge of the wire hole and the outer edge of the integrated motor is 1-2mm.

[0009] The quick-release centrifugal turntable has a ring-shaped confluence column around its protrusion structure to accelerate the flow of sprayed liquid toward the quick-release centrifugal turntable; quick-release centrifugal turntables with different shapes and structures will produce droplets of different sizes. The shape and structure features of quick-release centrifugal turntables include, but are not limited to, smooth circular plate, circular plate with corrugated edge, circular plate with guide groove, bowl-shaped plate, disc-shaped plate, etc.

[0010] The inlet pipe is L-shaped and passes through an integrated motor from top to bottom, delivering the sprayed liquid into the electrostatic sleeve.

[0011] The electrostatic sleeve is located between the integrated motor and the quick-release centrifugal turntable, and includes an upper electrode cover, an electrode, and a lower electrode cover. The upper electrode cover is fastened to the integrated motor by fastening bolts made of insulating material. The lower electrode cover is fixedly connected to the upper motor cover by threaded connection. The electrode is placed in the groove between the upper and lower electrode covers and fixed in the electrostatic sleeve. The wire connects the electrode to the high-voltage power supply through the wire hole. The position of the wire hole is consistent with the position of the wire hole on the upper electrode cover, and the width of the wire hole is not less than 4mm and not more than 10mm.

[0012] The inlet pipe outlet is longer at the top and shorter at the bottom, guiding the sprayed liquid downwards into the electrostatic sleeve and flowing towards the quick-release centrifugal nozzle.

[0013] The upper electrode cover has a protruding structure near the motor output end to prevent the sprayed liquid from contacting the motor output end.

[0014] The upper electrode cover has an arc-shaped structure inside, and the liquid sprayed from the inlet pipe flows quickly through the arc-shaped structure to the quick-release centrifugal turntable.

[0015] The upper electrode cover has a wire hole, the position of which is consistent with the position of the wire hole in the integrated motor, and the width of the wire hole is not less than 4mm and not more than 10mm.

[0016] The electrode thickness is not less than 1 mm and not more than 10 mm.

[0017] The rotation direction of the upper and lower electrode cover threads is opposite to the rotation direction of the motor.

[0018] Compared with the prior art, the quick-release electrostatic centrifugal nozzle of the present invention has the following advantages: 1. It applies electrostatic spraying technology to the aerospace plant protection centrifugal nozzle, realizing the combination of electrostatic spraying and aerospace centrifugal nozzle technology, improving the pesticide spraying effect and agricultural operation quality, and the electrodes are not exposed to the air, ensuring the safety of electrostatic use; 2. It realizes the quick replacement of the centrifugal disc of the centrifugal nozzle, and quickly and conveniently adjusts the particle size for different crops. Attached Figure Description

The structure has a ring-shaped confluence column 9 around its periphery to accelerate the flow of the sprayed liquid to the quick-release centrifugal turntable 10. The quick-release centrifugal turntable 10 has structural features including, but not limited to, a smooth circular plate, a circular plate with corrugated edges, a circular plate with guide grooves, a bowl-shaped plate, a disc-shaped plate, etc. The inlet pipe 2 is L-shaped, passing from top to bottom through the integrated motor 1, delivering the sprayed liquid into the electrostatic sleeve 3. The outlet of the inlet pipe 2 is longer at the top and shorter at the bottom, guiding the sprayed liquid downwards into the electrostatic sleeve 3, flowing towards the quick-release centrifugal nozzle 10, and preventing the sprayed liquid from contacting the motor output end. The electrostatic sleeve 3 is located within the integrated motor... Between the 1 and the quick-release centrifugal turntable 10, there is an upper electrode cover 12, an electrode 4, and a lower electrode cover 11. The upper electrode cover 12 is fastened to the integrated motor 1 by fastening bolts made of insulating material. The electrode is placed in the groove between the upper and lower electrode covers and is fixed in the electrostatic sleeve 3 by the upper electrode cover 12 and the lower electrode cover 11 being threaded together. The wire connects the electrode 4 to the high-voltage power supply through the wire hole 13. The position of the wire hole 13 is consistent with the position of the wire hole on the upper electrode cover, and the width of the wire hole 13 is not less than 4mm and not more than 10mm. The upper electrode cover 12 A protruding structure is provided at the upper part near the motor output end 14; the upper electrode cover 12 has an arc-shaped structure 5 inside, through which the sprayed liquid entering from the liquid inlet pipe 2 flows quickly to the quick-release centrifugal turntable 10; the upper electrode cover 12 has a wire hole 13, the position of which is consistent with the position of the wire hole 13 of the integrated motor 1, and the width of the wire hole 13 is not less than 4mm and not more than 10mm; the thickness of the electrode 4 is not less than 1mm and not more than 10mm; the thread rotation direction of the upper electrode cover 12 and the lower electrode cover 11 is opposite to the transmission direction of the motor output end 14.

When the quick-release centrifugal turntable 10 needs to be replaced, the quick-release centrifugal turntable 10 is pushed inward, and the spring 7 is compressed. Since the protrusion 8 of the quick-release centrifugal turntable is an arc shape that is narrow at the front and wide at the back, after pushing it inward, the quick-release centrifugal turntable 10 can be rotated until the motor output end 14 is no longer in the concave hole 6, and then it can be quickly pulled out.
