Description

Technical Field

[0002] The atomizer of a plant protection drone is a key component in its spraying system. It is used to evenly disperse liquid pesticides and fertilizers into tiny particles to more effectively cover the crop surface and improve the control effect. According to different needs and technical implementation methods, the atomizer of a plant protection drone can be mainly divided into pressure atomizers, centrifugal atomizers, and airflow-assisted atomizers. In citrus cultivation, plant protection drones are usually needed for spraying pesticides and fertilizing, which requires the use of centrifugal atomizers. Existing plant protection drone atomizers have the following problems when used: 1. When spraying pesticides and fertilizers on citrus trees, due to the dense branches and leaves of citrus trees, when using traditional atomizing devices for spraying pesticides, the atomized liquid has poor penetration power. Usually, the liquid can only cover the branches and leaves at the top of the citrus trees, and it is difficult to pass through the gaps and fall on the leaves below.

[0003] 2. When spraying pesticides, the atomization device of a plant protection drone usually uses a motor to drive the centrifugal disk to rotate to achieve centrifugal rotating atomization. The motor usually needs to work under high load, and the motor usually uses external heat dissipation fins for heat dissipation.

Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: See Figure 1 and Figure 2 The atomization device of the plant protection drone for citrus planting includes a top mounting seat 1 and a connecting arm 2. Two through holes 22 are symmetrically opened at the lower part of the top mounting seat 1. A No. 1 fixing hole 15 is opened on the top of the connecting arm 2. A No. 2 connecting rod 21 slides through the No. 1 fixing hole 15 and the two through holes 22. A nut 23 is threadedly connected to the rear end of the No. 2 connecting rod 21.

A number of heat dissipation fins 82 are evenly fixedly installed on the inner wall of the mounting groove 85, and plugs 16 are slidably inserted at the front and rear ends of the suction channel 84. The plug 16 is used to seal the suction channel 84 to prevent impurities from entering the suction channel 84 and causing blockage. A sealing sleeve 83 is commonly fixedly installed between multiple heat dissipation fins 82, and a servo motor 14 is fixedly installed inside the sealing sleeve 83. The bottom of the sealing sleeve 83 is fixedly connected to the bottom of the bottom sealing plate 81. The output end of the servo motor 14 rotates and passes through the bottom of the bottom sealing plate 81 and is fixedly connected to the connecting shaft 13. The connecting shaft 13 is fixedly connected to the limiting strip on the outside. There is a gap between the top of the sealing sleeve 83 and the inner wall of the mounting groove 85, which facilitates the entry of external cold air into the mounting groove 85.

[0024] During use, the suction mechanism 3 is used for suction, and the outside cold air enters the connecting hole 86 through the suction channel 84, and then the outside cold air enters the mounting groove 85. The heat generated by the servo motor 14 is conducted to the heat dissipating fins 82, and the outside cold air takes away the heat on the heat dissipating fins 82, thereby realizing rapid heat dissipation of the servo motor 14.

The bottom of the rotating shaft 315 is fixedly sleeved with a suction fan blade 317. A number of air inlet holes 319 are evenly opened at the bottom of the fixed seat 32. A one-way valve 34 is fixedly installed inside the air inlet hole 319. The air inlet hole 319 is located below the suction fan blade 317, which is convenient for using the suction fan blade 317 to transport the airflow from the central groove 33 to the bottom shell 4. The one-way valve 34 ensures that the outside air enters the bottom shell 4 from the central groove 33 in one direction.

[0027] When suction is required, the servo motor 14 is started, and the output end of the servo motor 14 drives the connecting shaft 13 and the limit bar thereon to rotate, and synchronously drives the No. 1 driving gear 318 to rotate, and at the same time drives the driven gear 316 and the rotating shaft 315 thereon to rotate. The gear ratio of the No. 1 driving gear 318 to the driven gear 316 is five to one, thereby realizing the rapid rotation of the rotating shaft 315 and the rapid rotation of the suction fan blade 317, thereby drawing the outside air from the suction channel 84 and the connecting hole 86 into the mounting groove 85, and then the air enters the center groove 33 from the gap between the center turntable 311 and the fixing ring 312, and then enters the bottom shell 4 through the air inlet hole 319, realizing suction and heat dissipation, and at the same time, the outside air sucked into the bottom shell 4 pressurizes the inner wall of the bottom shell 4.

[0028] See also Figure 2 、 Figure 3 、 Figure 6 、 Figure 9 and Figure 10 The top mounting seat 1 is detachably mounted on the bottom of the plant protection drone. A connecting wire 20 is provided inside the connecting arm 2. One end of the connecting wire 20 is connected to the servo motor 14.

A straight-line nozzle is provided on the nozzle 24, and a number of No. 1 split fins 25 are evenly fixedly connected to the bottom of the inner wall of the bottom shell 4.

[0029] During use, the connecting hose 18 is used to connect the connecting head 9 and the connecting water pipe 19, and then the top of the connecting water pipe 19 is connected to the water pump output end connector at the water tank of the plant protection drone. When spraying is required, the water pump is started to transport the liquid fertilizer and liquid pesticide in the water tank to the connecting water pipe 19 and the connecting hose 18, and then enter the bottom shell 4 through the connecting head 9. The liquid fertilizer and liquid pesticide are initially divided and atomized by the No. 1 dividing fin 25. The divided liquid fertilizer and liquid pesticide are sprayed out from the nozzle 24, and the air sucked into the bottom shell 4 from the outside world pressurizes the bottom shell 4, thereby increasing the pressure and initial velocity of the liquid fertilizer and liquid pesticide sprayed from the nozzle 24, and reducing the probability of nozzle 24 being blocked.

[0030] See also Figure 3 、 Figure 6 and Figure 7 The atomization mechanism 5 includes a first-level atomization assembly 51 and a second-level atomization assembly 52. ​​The second-level atomization assembly 52 is arranged below the first-level atomization assembly 51. The first-level atomization assembly 51 includes a rotating cover 511 rotatably sleeved on the bottom of the bottom shell 4.

A tightening bolt 7 is threadedly connected inside the threaded hole, and the top of the tightening bolt 7 fits with the bottom center of the conical block.

[0032] When in use, the rotation of the connecting shaft 13 drives the tightening bolt 7 to rotate, synchronously drives the conical block and the bottom rotating plate 522 thereon to rotate, and at the same time drives the cutting column 524 to rotate. The cutting column 524 is a multi-layer design, which gradually becomes denser from the center to the edge of the bottom rotating plate 522, thereby realizing multi-layer cutting of water flow and medicine.

Component 52 rotates in the opposite direction. After the medicine and water are sprayed out, the water enters between the top rotating ring 521 and the bottom rotating plate 522 from the No. 2 fixed hole 526, and the cutting column 524 is used to perform two-stage segmentation and atomization on the liquid fertilizer and liquid pesticide. After segmentation and atomization, they are sprayed onto the rotating cover 511, and the No. 2 segmentation fin 512 is used to perform three-stage segmentation and atomization.

At this time, start the water pump to pump the liquid Fertilizers and liquid pesticides are transported to the connecting water pipe 19 and the connecting hose 18, and then enter the bottom shell 4 through the connecting head 9.
