Description

Technical Field

[0001] This invention belongs to the field of atomization device technology, specifically relating to an atomization device for agricultural drones used in citrus cultivation. Background Technology

[0002] The atomizing device of an agricultural drone is a key component of its spraying system. It is used to evenly disperse liquid pesticides and fertilizers into tiny particles for more effective coverage of the crop surface and improved pest control. Based on different needs and technical implementation methods, agricultural drone atomizing devices can be mainly divided into pressure atomizing devices, centrifugal atomizing devices, and airflow-assisted atomizing devices. In citrus cultivation, agricultural drones are typically used for spraying pesticides and fertilizers, thus requiring the use of centrifugal atomizing devices. However, existing agricultural drone atomizing devices suffer from the following problems:

[0003] 1. When spraying pesticides and fertilizers on citrus trees, because the branches and leaves of citrus trees are relatively dense, the penetration of the atomized pesticide solution is poor when using traditional atomizing devices. Usually, the pesticide solution can only cover the branches and leaves at the top of the citrus tree and is difficult to pass through the gaps to fall on the lower leaves.

[0004] 2. When spraying pesticides, the atomizing device of agricultural drones usually uses a motor to drive the centrifugal disc to rotate and achieve centrifugal atomization. The motor usually needs to work under high load, and the motor usually uses external heat dissipation fins for heat dissipation, which has poor heat dissipation effect, thus affecting the normal operation of the motor and making it difficult to support the long-term operation of the equipment. Summary of the Invention

The secondary atomizing component is disposed below the primary atomizing component. The primary atomizing component includes a rotating cover that is rotatably sleeved on the bottom of the base shell.

Combined with the centrifugal atomization of the atomizing mechanism, pressurized atomization and centrifugal atomization are achieved, improving the atomization effect.

[0021] 2. Unlike existing technologies, this technology utilizes air pressurization to increase the initial velocity of the water jet from the nozzle, effectively reducing the probability of nozzle clogging. Furthermore, it employs a first-stage dividing fin to initially divide the water flow, a cutting column for secondary division, and a second-stage dividing fin for tertiary division, achieving multi-stage water flow segmentation and further enhancing the water atomization effect. In addition, the downward-facing rotating shroud enhances the downward penetration force of the atomized water flow.

[0022] 3. Unlike existing technologies, the first-stage atomizing component and the second-stage atomizing component can be rotated in opposite directions on the same axis using a single servo motor. This eliminates the need for two drive sources, resulting in lower costs and better atomization performance from the opposing rotation of the first-stage and second-stage atomizing components.

Detailed Implementation

[0034] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] Example: Please refer to Figure 1 and Figure 2 Atomizing device for agricultural drones used in citrus cultivation includes a top mounting base 1 and a connecting arm 2. The top mounting base 1 has two symmetrical through holes 22 at its lower part. The connecting arm 2 has a first fixing hole 15 at its top. A second connecting rod 21 slides through the first fixing hole 15 and the two through holes 22. The rear end of the second connecting rod 21 is threaded with a nut 23. The second connecting rod 21 is rotatably connected to the connecting arm 2. A top cover 6 is fixedly connected to the bottom of the connecting arm 2. The top cover 6 has a heat dissipation mechanism 8 inside for heat dissipation. The bottom of the top cover 6 has a suction mechanism 3 for air extraction for heat dissipation and pressurized atomization. The bottom of the suction mechanism 3 has a bottom shell 4. The bottom of the bottom shell 4 has an atomizing mechanism 5 for two-stage atomization.

[0036] In use, the top mounting base 1 is connected to the agricultural drone with screws. The second connecting rod 21 is rotatably connected to the connecting arm 2, which makes it easy to fold and store the connecting arm 2. The suction mechanism 3 is used to draw in outside air. The heat dissipation mechanism 8 dissipates heat from the components inside the atomizing device. The atomizing mechanism 5 is used to achieve two-stage atomization, which improves the water atomization spraying effect.

[0037] Please see Figure 1 , Figure 2 and Figure 3 The top cover 6 has four symmetrically arranged triangular grooves on its top, and each triangular groove has a countersunk threaded hole 11 at its bottom. A suction channel 84 is formed between two symmetrical triangular grooves. The bottom center of the top cover 6 has an installation groove 85, which is connected to the suction channel 84 through a connecting hole 86. Several heat dissipation fins 82 are evenly fixedly installed on the inner wall of the installation groove 85. Plugs 16 are slidably inserted into both ends of the suction channel 84 to seal the suction channel 84 and prevent impurities from entering and causing blockage. A sealing sleeve 83 is fixedly installed between the multiple heat dissipation fins 82. A servo motor 14 is fixedly installed inside the sealing sleeve 83. A bottom sealing plate 81 is fixedly connected to the bottom of the sealing sleeve 83. The output end of the servo motor 14 rotates through the bottom of the bottom sealing plate 81 and is fixedly connected to a connecting shaft 13. A limit strip is fixedly connected to the outside of the connecting shaft 13. There is a gap between the top of the sealing sleeve 83 and the inner wall of the installation groove 85 to facilitate the entry of cold air into the installation groove 85.

[0038] In use, the suction mechanism 3 is used to suction, and the outside cold air enters the connection hole 86 through the suction channel 84. Then the outside cold air enters the mounting slot 85. The heat generated by the servo motor 14 is conducted to the heat dissipation fins 82. The outside cold air carries away the heat on the heat dissipation fins 82, thus realizing rapid heat dissipation of the servo motor 14.

[0039] Please see Figure 2 , Figure 4 and Figure 5 The suction mechanism 3 includes a drive assembly 31 and a fixed base 32. The drive assembly 31 is mounted on the fixed base 32. The fixed base 32 has several first-order connecting holes 12 and a central groove 33 at the top center of the fixed base 32. The drive assembly 31 includes a fixed ring 312 fixedly mounted on the top of the fixed base 32. The fixed ring 312 has several second-order connecting holes 314 that correspond one-to-one with the first-order connecting holes 12. Several first-order connecting rods 313 are uniformly fixedly connected to the inner wall of the fixed ring 312. A central turntable 311 is fixedly connected to the multiple first-order connecting rods 313.

[0040] Please see Figure 2 , Figure 4 and Figure 5The connecting shaft 13 is sealed and rotates through the center turntable 311 and the center of the fixed seat 32. A first driving gear 318 is fixedly sleeved on the upper part of the connecting shaft 13. Several rotating shafts 315 are evenly installed at the bottom of the fixed ring 312. Several driven gears 316 that mesh with the first driving gear 318 are fixedly sleeved in the middle of the multiple rotating shafts 315. Suction fan blades 317 are fixedly sleeved at the bottom of the rotating shafts 315. Several air inlets 319 are evenly opened at the bottom of the fixed seat 32. A one-way valve 34 is fixedly installed inside the air inlet 319. The air inlet 319 is located below the suction fan blades 317, which facilitates the use of the suction fan blades 317 to transport airflow from the center groove 33 to the bottom shell 4. The one-way valve 34 ensures that outside air enters the bottom shell 4 from the center groove 33 in one direction.

[0041] When suction is required, the servo motor 14 is started. The output of the servo motor 14 drives the connecting shaft 13 and the limit strip on it to rotate, which in turn drives the first driving gear 318 to rotate. At the same time, it drives the driven gear 316 and the rotating shaft 315 on it to rotate. The gear ratio of the first driving gear 318 to the driven gear 316 is five to one, which realizes the rapid rotation of the rotating shaft 315 and the rapid rotation of the suction fan blade 317. This draws outside air from the suction channel 84 and the connecting hole 86 into the mounting groove 85. Then, the air enters the central groove 33 through the gap between the central turntable 311 and the fixing ring 312, and then enters the bottom shell 4 through the air inlet 319, realizing suction and heat dissipation. At the same time, the air drawn into the bottom shell 4 pressurizes the inner wall of the bottom shell 4.

[0042] Please see Figure 2 , Figure 3 , Figure 6 , Figure 9 and Figure 10 The top mounting base 1 is detachably installed on the bottom of the agricultural drone. A connecting wire 20 is installed inside the connecting arm 2. One end of the connecting wire 20 is connected to the servo motor 14, and the other end is electrically connected to the power supply terminal of the agricultural drone. Several threaded blocks 10, corresponding one-to-one with the positions of the first connecting hole 12, are evenly fixedly installed on the inner wall of the top of the bottom shell 4. The fixing bolt 17 passes through the countersunk threaded hole 11, the second connecting hole 314, and the first connecting hole 12, and is threaded into the inside of the threaded block 10. The top right side of the bottom shell 4... A connector 9 is fixedly installed, with its bottom connected to the inside of the bottom shell 4. A connecting hose 18 is fixedly sleeved on the top of the connector 9, and a connector water pipe 19 is fixedly sleeved on the top of the connecting hose 18. The connector water pipe 19 is connected to the water pump inside the water tank of the agricultural drone through a connecting pipe. The lower part of the connecting shaft 13 is sealed and rotates through the center of the bottom of the bottom shell 4. Several nozzles 24 are evenly fixedly installed on the outer circumference of the bottom of the bottom shell 4. A straight nozzle is opened on the nozzle 24. Several No. 1 segmented fins 25 are evenly fixedly connected to the bottom of the inner wall of the bottom shell 4.

[0043] In use, the connector 9 and the connector water pipe 19 are connected by the connecting hose 18. Then, the top of the connector water pipe 19 is connected to the water pump output connector at the water tank of the plant protection drone. When spraying is needed, the water pump is started to deliver the liquid fertilizer and liquid pesticide in the water tank to the connector water pipe 19 and the connecting hose 18. Then, it enters the bottom shell 4 through the connector 9. The liquid fertilizer and liquid pesticide are initially atomized by the first dividing fin 25. The atomized liquid fertilizer and liquid pesticide are sprayed out from the nozzle 24. The air drawn into the bottom shell 4 from the outside pressurizes the bottom shell 4, which increases the pressure and initial velocity of the liquid fertilizer and liquid pesticide sprayed from the nozzle 24, while reducing the probability of the nozzle 24 being blocked.

[0044] Please see Figure 3 , Figure 6 and Figure 7 The atomizing mechanism 5 includes a primary atomizing component 51 and a secondary atomizing component 52. The secondary atomizing component 52 is located below the primary atomizing component 51. The primary atomizing component 51 includes a rotating cover 511 rotatably sleeved on the bottom of the bottom shell 4. Several secondary segmented fins 512 are uniformly fixedly installed on the inner wall of the bottom of the rotating cover 511. A secondary gear ring 516 is fixedly installed on the bottom of the rotating cover 511. A fixing block 517 is fixedly installed on the outside of the bottom shell 4. A fixing shaft 514 is rotatably installed on the fixing block 517. A secondary drive gear 513 that meshes with the secondary gear ring 516 is fixedly sleeved at the end of the fixing shaft 514 away from the fixing block 517.

[0045] Please see Figure 6 and Figure 8 The second atomizing component 52 includes a top rotating ring 521 rotatably fitted onto the bottom of the base shell 4. A first gear ring 515, meshing with the second drive gear 513, is fixedly mounted on the top of the top rotating ring 521. A connecting ring 525 is fixedly mounted on the bottom of the top rotating ring 521. Several second fixing holes 526, corresponding one-to-one with the positions of the nozzles 24, are evenly opened on the connecting ring 525. A bottom rotating plate 522 is fixedly mounted on the bottom of the connecting ring 525. Several cutting water flow devices are evenly fixedly mounted on the top of the bottom rotating plate 522. A cutting column 524, a number of connecting plates 523 are fixedly installed between the bottom edge of the top rotating ring 521 and the top edge of the bottom rotating plate 522. The bottom seal of the connecting shaft 13 passes through the bottom center of the bottom of the bottom rotating plate 522. A limiting groove that matches the limiting strip is opened at the connection between the bottom rotating plate 522 and the connecting shaft 13. A conical block is installed at the bottom of the bottom rotating plate 522, and a threaded hole is opened at the bottom center of the connecting shaft 13. A tightening bolt 7 is threaded inside the threaded hole, and the top of the tightening bolt 7 fits against the bottom center of the conical block.

[0046] In use, the rotation of the connecting shaft 13 drives the tightening bolt 7 to rotate, which in turn drives the conical block and its bottom rotating plate 522 to rotate, and simultaneously drives the cutting column 524 to rotate. The cutting column 524 has a multi-layer design, gradually becoming denser from the center of the bottom rotating plate 522 to the edge, achieving multi-layer cutting of water flow and medicine. The first gear ring 515 rotates, which in turn drives the second drive gear 513 and its fixed shaft 514 to rotate, and simultaneously drives the second gear ring 516 and its rotating cover 511 to rotate in the opposite direction, simultaneously achieving the opposite rotation of the second dividing fins 512. Thus, the first-stage atomizing component 51 and the second atomizing component are realized using a single servo motor 14. Component 52 rotates in opposite directions. After the pesticide and water are sprayed out, the water enters from the second fixing hole 526 between the top rotating ring 521 and the bottom rotating plate 522. The liquid fertilizer and liquid pesticide are atomized in two stages using the cutting column 524. After atomization, the liquid fertilizer and liquid pesticide are sprayed onto the rotating cover 511. The second dividing fin 512 performs tertiary atomization. The rotating cover 511 is designed with an opening facing downwards. The liquid fertilizer and liquid pesticide after multi-stage atomization are sprayed downwards, which improves the penetration and downward pressure of the atomized liquid fertilizer and liquid pesticide, resulting in good atomization effect. Furthermore, the first-stage atomization component 51 and the second-stage atomization component 52 rotate in opposite directions, further improving the atomization effect.

[0047] It should be noted that the atomizing device of this agricultural drone used for citrus cultivation, when in use, such as... Figure 10As shown, firstly, the top mounting bracket 1 is installed onto the agricultural drone using screws. Then, the top of the connector water pipe 19 is connected to the water pump output connector at the water tank of the agricultural drone. Next, the connecting wire 20 is connected to the power supply terminal of the agricultural drone. At this time, the servo motor 14 is started. The output of the servo motor 14 drives the connecting shaft 13, which in turn drives the first drive gear 318 to rotate. Simultaneously, it drives the driven gear 316 and its rotating shaft 315 to rotate, which in turn drives the suction fan blade 317 to rotate rapidly. This draws outside air into the mounting groove 85 through the suction channel 84 and the connecting hole 86. Then, the air enters the central groove 33 through the gap between the central turntable 311 and the fixing ring 312, and then enters the bottom shell 4 through the air inlet 319, thus pressurizing the inside of the bottom shell 4. At this time, the water pump is started to pump the liquid... Fertilizer and liquid pesticide are delivered to the connector water pipe 19 and the connecting hose 18, and then enter the bottom shell 4 through the connector 9. The liquid fertilizer and liquid pesticide are initially atomized by the first dividing fin 25. The atomized liquid fertilizer and liquid pesticide are sprayed out from the nozzle 24. The air drawn into the bottom shell 4 from the outside pressurizes the bottom shell 4, which increases the pressure and initial velocity of the liquid fertilizer and liquid pesticide sprayed from the nozzle 24, and at the same time reduces the probability of nozzle 24 clogging. At the same time, the connecting shaft 13 drives the first-stage atomizing component 51 and the second-stage atomizing component 52 to rotate in opposite directions. The second-stage atomizing component 52 is used for second-stage atomization, and the first-stage atomizing component 51 is used for third-stage atomization. This achieves multi-stage atomization of liquid fertilizer and liquid pesticide, and the combination of air pressure atomization and rotary centrifugal atomization improves the atomization effect.

[0048] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
