[0043] Please see Figures 1 to 4 One embodiment of the air-driven oscillating sprayer is mainly used for spraying pesticides in orchards to prevent orchard diseases and pests. The air-driven oscillating sprayer includes a tractor unit 10 and a spraying device 20. The spraying device 20 includes a vehicle body 100, a spraying assembly 200, an air supply assembly 300, and an oscillating assembly 400. The tractor unit 10 is detachably connected to the vehicle body 100 and is used to drive the vehicle body 100 to move. Driving the vehicle body through the tractor unit improves the efficiency of pesticide spraying.

[0044] In this embodiment, the spraying assembly 200 is installed on the vehicle body 100 and is used to atomize and spray the drug to facilitate drug diffusion. The air supply assembly 300 is installed on the vehicle body 100 and is used to blow air onto the atomized drug to facilitate the diffusion of the drug to a preset area, thereby realizing the spraying of fruit trees. The swaying assembly 400 is installed on the vehicle body 100 and is connected to the spraying assembly 200 in a transmission connection so as to drive the spraying end of the spraying assembly 200 to sway, thereby increasing the diffusion area of ​​the drug.

[0045] With this setup, as the tractor unit 10 pulls the spraying device 20, the spraying component 200 first atomizes the pesticide, and the air supply component 300 then blows the atomized pesticide toward the preset area, which facilitates efficient spraying of pesticides in the orchard. Since the swaying component 400 can also drive the spraying end of the spraying component 200 to sway, it can also increase the spraying range of the pesticide and further improve the spraying efficiency.

[0048] In one embodiment, please refer to Figures 1 to 4 The air supply assembly 300 includes a ventilation duct 310 and a blower 320. The ventilation duct 310 includes an air inlet end 311 and an air outlet end 313, as well as a flexible hose body 312 connecting the air inlet end 311 and the air outlet end 313. The blower 320 is installed at the air inlet end 311 and is used to blow air onto the air inlet end 311 so that air can pass through the flexible hose body 312 and be blown out from the air outlet end 313. The atomizing nozzle 240 is installed at the air outlet end 313 and is used to blow air onto the atomized medicine after atomization by the atomizing nozzle 240. The blower 320 provides airflow and the ventilation duct 310 restricts the airflow direction. Specifically, the ventilation duct 310 is a flexible hose.

[0049] In one embodiment, please refer to Figures 1 to 4 Two sets of air supply components 300 are provided and symmetrically arranged on both sides of the vehicle body 100. Two atomizing nozzles 240 are provided and are respectively arranged on the blowing end 313 of each air supply component 300, so as to facilitate the spraying of medicine from both sides of the wind-driven swing sprayer and improve the efficiency of medicine spraying.

[0050] In one embodiment, please refer to Figures 1 to 4 The first transmission assembly also drives the output shaft 11 and each blower 320, and drives each blower 320 to blow air onto each air inlet 311. By setting the first transmission assembly, the same power source can not only drive the drug delivery pump 230 to deliver drugs, but also drive the blower 320 to blow air, saving the use of the power source and saving costs.

[0051] Specifically, the first transmission assembly includes a first transmission member 510, a second transmission member 520, a third transmission member 530, a fourth transmission member 540, a first transmission belt 550, a second transmission belt 560, and a third transmission belt 570; the first transmission member 510 and the second transmission member 520 are both rotatably connected to the vehicle body 100, the third transmission member 530 is connected to the power shaft of the medicine delivery pump 230, and there are two fourth transmission members 540, which are respectively connected to the power shafts of each blower 320; the first transmission member 510 is provided with a first tooth 511, the second transmission member 520 is provided with a second tooth 521, a third tooth 522, and a fourth tooth 523 coaxially connected, the third transmission member 530 is provided with a fifth tooth 531, and the fourth transmission member 540 is provided with a sixth tooth 541.

[0052] Figure 3 This is a structural diagram of the spraying device 20 near the side of the tractor head 10. Figure 4 This is a schematic diagram of the spraying device 20 on the side opposite to the tractor head 10.

[0053] In this embodiment, the first transmission belt 550 is wound between the first toothed portion 511 and the second toothed portion 521, thereby transmitting rotational motion from the first transmission member 510 to the second transmission member 520. The second transmission belt 560 is wound between the third toothed portion 522 and the fifth toothed portion 531, thereby transmitting rotational motion from the second transmission member 520 to the third transmission member 530. The rotation of the third transmission member 530 can drive the drug delivery pump 230 to work. By configuring the tooth diameters of the first toothed portion 511, the second toothed portion 521, the third toothed portion 522 and the fifth toothed portion 531, the transmission ratio from the first transmission member 510 to the third transmission member 530 can be configured, so that the rotational speed of the third transmission member 530 meets the working requirements of the drug delivery pump 230.

[0054] Furthermore, the third transmission belt 570 is wound between the fourth tooth portion 523 and the sixth tooth portion 541 of each of the fourth transmission members 540, thereby transmitting rotational motion from the second transmission member 520 to the fourth transmission member 540. The rotation of the fourth transmission member 540 can drive the blower 320 to work. By configuring the tooth diameters of the first tooth portion 511, the second tooth portion 521, the fourth tooth portion 523, and the sixth tooth portion 541, the transmission ratio from the first transmission member 510 to the fourth transmission member 540 can be configured, so that the rotational speed of the fourth transmission member 540 meets the working requirements of the blower 320. Specifically, the first transmission belt 550, the second transmission belt 560, and the third transmission belt 570 are all provided with tooth profiles corresponding to each tooth portion.

[0055] Of course, in other embodiments, the teeth of each transmission component in the first transmission assembly can be replaced with pulleys, and each transmission belt in the first transmission assembly can be replaced with a belt; or, the pneumatic swing sprayer can also be provided with a first drive device, which is connected to the blower 320 and drives the blower 320 to work with an independent power source.

[0056] In one embodiment, please refer to Figures 1 to 4 The spraying device 20 also includes a second transmission assembly, which is connected to the third transmission component 530 and the oscillating assembly 400. This allows the oscillating assembly 400 to drive each atomizing nozzle 240 to oscillate. By providing the second transmission assembly, the same power source can not only drive the drug delivery pump 230 to deliver drugs and the blower 320 to blow air, but also drive the oscillating assembly 400 to oscillate each atomizing nozzle 240, saving on the use of a power source and reducing costs. Specifically, the blowing end 313 of each air supply assembly 300 is rotatably connected to the vehicle body 100, allowing the blowing end 313 to oscillate to change the direction of the spraying end.

[0057] Specifically, the atomizing nozzle 240 includes an annular tube and several nozzles evenly distributed around the circumference of the ambient tube, thereby ensuring the uniformity and reliability of atomization.

[0058] In this embodiment, the swing assembly 400 includes a swing rod 410 and a linkage rod 420. The second transmission assembly is connected to the swing rod 410 and is used to drive the swing rod 410 to swing the blowing end 313 of one of the two air supply assemblies 300. The two ends of the linkage rod 420 are respectively rotatably connected to the blowing ends 313 of the two air supply assemblies 300, so that the swinging motion of the blowing end 313 of one of the two air supply assemblies 300 can drive the blowing end 313 of the other air supply assembly 300 to swing. Thus, through the linkage relationship of the linkage rod 420, the blowing ends 313 of the two air supply assemblies 300 can be driven to swing alternately at the same time.

[0059] Specifically, the second transmission assembly includes a fifth transmission member 610, a sixth transmission member 620, a gearbox 630, a seventh transmission member 640, an eccentric transmission member 650, a fourth transmission belt 660, and a fifth transmission belt 670. The fifth transmission member 610 is provided with a seventh tooth 611, the sixth transmission member 620 is provided with an eighth tooth 621, the seventh transmission member 640 is provided with a ninth tooth 641, the seventh transmission member 640 is provided with a tenth tooth 651, and an eccentric shaft 652 is eccentrically disposed relative to the tenth tooth 651.

[0060] In this embodiment, the fifth transmission member 610 is connected to the power shaft of the drug delivery pump 230, and the fourth transmission belt 660 is wound around the seventh tooth portion 611 and the eighth tooth portion 621, thereby enabling the rotational motion to be transmitted from the fifth transmission member 610 to the sixth transmission member 620. The sixth transmission member 620 and the seventh transmission member 640 are respectively connected to the input side shaft and the output side shaft of the gearbox 630, thereby enabling the rotational motion to be transmitted from the sixth transmission member 620 to the seventh transmission member 640. The fifth transmission belt 670 is wound around the ninth tooth portion 611. 41 and the tenth tooth 651, thereby enabling the rotational motion to be transmitted from the seventh transmission member 640 to the eccentric transmission member 650, which is rotatably connected to the vehicle body 100. One end of the rocker arm 410 is rotatably connected to the eccentric shaft 652, and the other end is rotatably connected to the blowing end 313 of one of the two air supply assemblies 300. Thus, the rotation of the eccentric transmission member 650 can drive the rocker arm 410 to pull the blowing end 313 of one of the two air supply assemblies 300 to rock.

[0061] By configuring the tooth diameters of the seventh tooth section 611, the eighth tooth section 621, the ninth tooth section 641, and the tenth tooth section 651, as well as the transmission ratio of the gearbox 630, the transmission ratio from the first transmission member 510 to the eccentric transmission member 650 can be configured, thereby ensuring that the rotational speed of the eccentric transmission member 650 meets the operational requirements of the rocking assembly 400. Specifically, the fourth transmission belt 660 and the fifth transmission belt 670 are both provided with tooth profiles corresponding to each tooth section.

[0062] Understandably, since the frequency of the oscillating motion of the oscillating component 400 should not be too high, the gearbox 630 is a reduction gearbox to configure the oscillating frequency of the oscillating component 400. Specifically, the drug delivery pump 230 can be selected as a high-pressure spraying pump, which facilitates the atomizing nozzle 240 to atomize and spray the drug. Simultaneously, to match the rotational speed requirements of the drug delivery pump 230 and the blower 320, the spraying component 200 may also include a pump gearbox, and the air delivery component 300 may also include a blower gearbox. The pump gearbox is driven between the fourth transmission component 540 and the power shaft of the blower 320, and is used to meet the rotational speed requirements of the blower 320. The blower gearbox is driven between the third transmission component 530 and the power shaft of the drug delivery pump 230, and is used to meet the rotational speed requirements of the drug delivery pump 230.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
