[0019] Overall, the present application provides a rubber tree disease and pest control drug spraying device, comprising a unmanned aerial vehicle body 1, a mounting seat 2 fixedly arranged at the bottom of the unmanned aerial vehicle body 1, a storage cavity 3 fixedly arranged at the bottom of the mounting seat 2, a fixed frame 4 fixedly arranged on the side wall of the storage cavity 3 in a door shape, and a spraying assembly symmetrically arranged on the two opposite sides of the fixed frame 4; The spraying assembly comprises a connecting frame 9 fixedly arranged on the fixed frame 4, a first mounting rod 5 and a second mounting rod 7 arranged on the connecting frame 9, and an arc-shaped adjusting piece 6 hingedly arranged at the end of the inner side of the first mounting rod 5 and the second mounting rod 7 close to each other, a liquid spraying pipe 601 conforming to the contour thereof fixedly arranged on the opposite side of the two adjusting pieces 6, a plurality of first nozzles 602 uniformly arranged on each liquid spraying pipe 601, and a connecting pipe 605 communicating between the two liquid spraying pipes 601 on the same side, and a liquid supply pipe 12 communicatingly arranged at the bottom of the storage cavity 3, the liquid supply pipe 12 extending to the inner side of the fixed frame 4, and the liquid spraying pipes 601 on the two sides communicating with the liquid supply pipe 12 through the extension pipe 11. Further, the first mounting rod 5 and the second mounting rod 7 are provided with elastic members between the first mounting rod 5 and the second mounting rod 7 and the adjusting piece 6, the first mounting rod 5 and the second mounting rod 7 are provided with a slot 501 on the side wall, the adjusting piece 6 is provided with a pull rope 604, one end of the pull rope 604 is fixedly connected with the adjusting piece 6, and the other end of the pull rope 604 passes through the slot 501 and is connected with the power assembly arranged on the fixed frame 4.

[0020] In the present embodiment, the spraying assembly can be moved up and down along the height direction of the rubber tree by the unmanned aerial vehicle body 1 to spray the drug more comprehensively, in the spraying assembly, the adjusting pieces 6 on the two sides of the connecting frame 9 can surround the trunk of the rubber tree, so that the first nozzles 602 spray the drug around the trunk, improve the precision of drug spraying, prevent the waste of drug, increase the prevention and control effect, and reduce the labor intensity.

[0021] In addition, the power assembly drives the pull rope 604 to enable the adjusting piece 6 to rotate at the hinge point, and the opening size of the two adjusting pieces 6 is adjusted by adjusting the rotation angle, so that the distance between the liquid spraying pipe 601 and the vertical rod is controlled, and different diameters of the tree trunks are adapted, and the adaptability of the device is increased based on the design.

[0022] In specific implementation, after the unmanned aerial vehicle body 1 flies to the specified position, the power assembly drives the two adjusting pieces 6 to rotate outward, the opening is adjusted to the maximum, then the unmanned aerial vehicle moves forward, the tree trunk is placed between the two adjusting pieces 6, the water pump in the storage cavity 3 is started, the medicine is pumped into the liquid spraying pipe 601 through the liquid supply pipe 12 along the extension pipe 11, and finally sprayed out by the first spray head 602, and finally the unmanned aerial vehicle moves up and down to adjust different spraying heights, so that the tree trunks of rubber trees are completely sprayed with medicine.

[0023] It should be noted that the elastic member can provide a restoring force for the adjusting piece 6, so that the adjusting piece 6 can rotate inward to the initial position. As a preferred embodiment, the elastic member is a spring 603, one end of the spring 603 is fixedly connected with the adjusting piece 6, and the other end is fixedly connected with the first mounting rod 5 or the second mounting rod 7. Of course, other components can also be selected to meet the requirements of the adjusting piece 6, and will not be further limited here.

[0024] In detail, compared with the traditional manual backpack spraying medicine, the device can save manpower and material resources, improve the spraying effect and spraying precision, and can adapt to the centralized prevention and control needs of large-scale plantations.

[0025] The power assembly includes a first fixed piece 801 and a second fixed piece 802 fixedly arranged on one side of the fixed frame 4, both ends of the connecting frame 9 are fixedly connected with the first fixed piece 801 and the second fixed piece 802, a rotating shaft 8 is rotatably connected between the first fixed piece 801 and the second fixed piece 802, the pull rope 604 is wound around the rotating shaft 8, the second fixed piece 802 has a first motor 803 fixedly arranged on the side wall, and an output shaft of the first motor 803 is fixedly connected with the rotating shaft 8.

[0026] In specific implementation, the first motor 803 drives the rotating shaft 8 to rotate in opposite directions, so that the pull rope 604 wound around the rotating shaft 8 is tightened and loosened, and the adjusting piece 6 adjusts the opening angle of the opening, so that different diameters of the tree trunks are adapted, In order to further adapt to different diameters of the tree trunks, in the embodiment, a first connecting sleeve 901 is fixedly arranged on the connecting frame 9, the connecting frame 9 is slidably provided with a second connecting sleeve 902, and the two adjusting pieces 6 are fixedly connected with the bottoms of the first connecting sleeve 901 and the second connecting sleeve 902, respectively.

[0027] It should be noted that by driving the second connecting sleeve 902 to slide on the connecting frame 9, the distance between the first connecting sleeve 901 is adjusted, thereby driving the two sides of the adjusting piece 6 to adjust the distance therebetween, further increasing the adaptability to different thickness of the tree trunk.

[0028] It should be further noted that in order to cooperate with the adjustment of the distance between the two sides of the adjusting piece 6, the connecting pipe 605 is a corrugated hose, which has a certain flexibility and bending property. Specifically, when the second connecting sleeve 902 drives the adjusting piece 6 to slide, it will not affect the communication between the two sides of the liquid spraying pipe 601.

[0029] Based on the above setting, in order to facilitate the adjustment of the distance between the second connecting sleeve 902 and the first connecting sleeve 901, in the embodiment, the rear side of the first connecting sleeve 901 is fixedly provided with a second motor 10, the side wall of the connecting frame 9 is fixedly provided with an abutting plate 1003, and the second connecting sleeve 902 is fixedly provided with a fixed block 1002. The output shaft of the second motor 10 is fixedly connected with the end of a screw rod 1001, the other end of the screw rod 1001 is rotationally connected with the abutting plate 1003, and the fixed block 1002 is threadedly connected with the screw rod 1001.

[0030] By controlling the screw rod 1001 to rotate forward and backward through the forward and reverse rotation of the motor, the fixed block 1002 can be driven to move, thereby driving the second connecting sleeve 902 to slide on the connecting frame 9. In addition, the screw rod 1001 has a self-locking property. When the motor stops rotating, the fixed block 1002 will be automatically locked in the current position due to the friction between the threads, and will not move due to external force, thereby ensuring the stability and reliability during work.

[0031] As a preferred structure of the embodiment, in order to be able to meet the spraying of drugs to the high position of rubber trees or the position of tree crowns, as shown in Figure 1 、 Figure 2 and Figure 5 , a vertical pipe 13 is vertically connected to the liquid supply pipe 12, the top end of the vertical pipe 13 is connected with a housing 1301, the top of the housing 1301 is provided with a recess, the recess is fixedly provided with a fan 1303, and a plurality of second nozzles 1302 are spaced apart around the fan 1303 at the top of the housing 1301.

[0032] It should be noted that with the assistance of the airflow of the fan 1303, the drug liquid sprayed by the second nozzle 1302 obtains additional rising kinetic energy, reducing the waste of drug liquid in non-target areas, and ensuring that the drug liquid can be accurately delivered to the area where the pests and diseases need to be prevented and controlled.

[0033] In the specific implementation, the medicine liquid is pumped into the liquid supply pipe 12, and then guided upward by the vertical pipe 13 to enter the inside of the top shell 1301. The medicine liquid entering the shell 1301 is distributed to the multiple second nozzles 1302 around the fan 1303. The second nozzles 1302 are opened, and the medicine liquid is sprayed upward and around the top of the shell 1301 under the pressure, forming an umbrella-shaped medicine mist area. Then the fan 1303 is started, which generates an upward axial airflow in the same direction as the vertical pipe 13 axis, giving the medicine a guiding force upward, so that the medicine is sprayed higher and farther, increasing the height and range of spraying. In addition, the airflow of the fan 1303 not only transports the medicine mist, but also slightly disturbs the branches and leaves, so that the medicine mist has the opportunity to contact the leaf surface at more angles, increasing the pest control effect.

[0034] In the spraying of medicine, the medicine liquid diffuses. In order to reduce the splashing of medicine spraying, the two sides of the mounting seat 2 are fixedly connected with the shielding assembly, which includes the connecting column 14 and the shielding plate 1401. One end of the connecting column 14 is fixedly connected with the mounting seat 2, and the other end is fixedly connected with the shielding plate 1401. The shielding plate 1401 is perpendicular to the connecting column 14, and the fixed frame 4 is located between the two shielding plates 1401.

[0035] The two shielding plates 1401 hold the spraying assembly in the middle, reducing the range of influence during medicine spraying. In addition, it can also prevent external factors from interfering with the medicine spraying of the spraying assembly, increasing the stability of medicine spraying.

[0036] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
