Description

Technical Field

[0001] This utility model relates to the field of agricultural drone technology, specifically to a pesticide spraying device for agricultural drones. Background Technology

[0002] With the acceleration of agricultural modernization, agricultural drones have been widely used in pest and disease control in farmland, orchards, and other crops due to their advantages such as high operational efficiency, wide coverage, and reduced manual labor intensity. As the core actuator of agricultural drones, the performance of the pesticide spraying device directly affects the uniformity of pesticide application, operational endurance, and ease of equipment maintenance, and is crucial to ensuring the effectiveness of pest and disease control.

[0003] Traditional agricultural drones often use a method of premixing pesticide solution on the ground and then injecting it into the storage tank. During flight operations, the pesticide solution is prone to stratification or sedimentation due to factors such as aircraft vibration and static placement, resulting in uneven concentration of the sprayed solution and thus affecting the control of pests and diseases. After the application of pesticides, pesticide residue is easily left at the nozzles of the spray head, especially for pesticides containing powder or thickeners. After natural air drying, the residue will solidify and clump, causing the nozzles to become blocked, affecting the uniformity of subsequent spraying, or even causing the spray head to fail.

[0004] Therefore, this utility model proposes a plant protection drone spraying device. Utility Model Content

The support base 403 is fixedly installed on the bottom of the UAV 1, providing a stable installation support point for the liquid storage tank 404. The insert plate 405, in conjunction with the support base 405, enables the positioning and installation of the liquid storage tank 404. The insert plate 405 is fixedly installed on the top of the liquid storage tank 404. The liquid storage tank 404 is used to store the pesticide solution to be sprayed, providing a pesticide reserve space for application and ensuring operational continuity. The insert plate 405 is inserted into the support base 403 from one end and fixed by bolts, enabling quick installation and removal of the liquid storage tank 404 for easy equipment maintenance. A pesticide replenishment port is also provided at one end of the liquid storage tank 404. A water pump 402 and a spray head 401 are installed at the end of the arm 2 near the propeller 3. The water pump 402 is connected to the spray head 401 and the liquid storage tank 404 via water pipes. One end of the water pump 402's water pipe is inserted into the liquid storage tank 404 for easy disconnection. The system provides power for the delivery of the pesticide solution, pressurizes the pesticide solution in the storage tank 404 and delivers it to the spray head 401. The spray head 401 receives the pesticide solution delivered by the water pump 402 and atomizes or sprays the solution to evenly cover the target crop area and complete the pesticide application.

[0019] like Figure 2 and Figure 4As shown, the drive assembly 5 includes a first support plate 501, a connecting shaft 502, a second support plate 503, and connecting grooves 510. One end of the first support plate 501 is fixedly installed on one side of the UAV 1, providing a support base for the connecting shaft 502. The other end of the first support plate 501 is rotatably connected to the top of the connecting shaft 502. The top of the connecting shaft 502 is rotatably engaged with the first support plate 501, and the bottom is connected to the second support plate 503. The horizontal position and angle of the second support plate 503 can be adjusted by rotation to adapt to different operational needs. Connecting grooves 510 are evenly distributed on the top of the connecting shaft 502. Four connecting grooves 510 are evenly distributed circumferentially on the top of the connecting shaft 502, and the included angle between adjacent connecting grooves 510 is 90 degrees. The bolts on the top of the first support plate 501 are threaded into the connecting groove 510. A second support plate 503 is installed at the bottom of the connecting shaft 502. The second support plate 503 provides stable mounting support for the motor 504 and the connecting seat 505, and transmits the positioning angle of the connecting shaft 502. A motor 504 is installed at the bottom of the other end of the second support plate 503. The motor 504 is powered by the UAV 1 battery. The connecting seat 505 is rotatably mounted on the top of the second support plate. The output end of the motor 504 is connected to the connecting seat 505, providing output power for the rotation of the connecting seat 505. A hexagonal slot is provided at the center of the top of the connecting seat 505. The slot of the connector 505 is used to connect with the plug 602. The top of the connector 505 is also provided with a slot 506. The side wall of the connector 505 is hinged to a support piece 507. One side of the support piece 507 is provided with a brush 508. The other side of the support piece 507 is fixedly installed with a clip 509. After the support piece 507 is flipped, it can fit over the top of the connector 505 with the side with the brush 508 facing upward. The clip 509 is inserted into the slot 506 to limit the support piece 507. The rotating connector 505 drives the support piece 507 and the brush 508 to rotate. The rotating brush 508 can be used to clean the bottom of the spray head 401.

[0020] like Figures 5-6 As shown, the mixing assembly 6 includes a mixing rod 604, which is rotatably and sealed inside the storage tank 404. The mixing rod 604 has stirring blades. When the mixing rod 604 rotates, it stirs the liquid in the tank, breaking up the stratification and sedimentation of the liquid, and ensuring that the liquid is mixed evenly. A hexagonal socket 601 is installed at the bottom of the mixing rod 604. The socket 601 is connected to the plug 602 and receives the rotational power transmitted by the plug 602 to drive the mixing rod 604 to rotate. A guide groove 603 is provided on the side wall of the socket 601. A hexagonal plug 602 is slidably installed at the bottom of the socket 601. The protrusion on the side wall of the plug 602 is slidably set in the guide groove 603 for lifting the plug 602 upward. The plug 602 is inserted into the connecting seat 505 below and connected by bolts, so that the plug 602 can be rotated through the connecting seat 505.

[0021] The working principle of this utility model is as follows: the insert plate 405 is inserted into one end of the support base 403 and then fixed with bolts to complete the positioning and installation of the liquid storage tank 404; then the liquid to be sprayed is injected through the liquid replenishment port at one end of the liquid storage tank 404. The liquid storage tank 404 provides liquid storage space for the application operation and ensures the continuity of the operation. Pull the plug 602 down and insert it into the hexagonal slot at the top of the lower connector 505, connecting it with bolts. Start the motor 504 at the bottom of the other end of the second support plate 503. The motor 504 drives the connector 505 to rotate, and the connector 505 rotates synchronously, driving the plug 602 to rotate as well. The plug 602 connects with the socket 601, transmitting the rotational power to the mixing rod 604, causing the mixing rod 604 to rotate in a sealed manner inside the storage tank 404, stirring the liquid inside and breaking up the stratification and sedimentation of the liquid. To ensure uniform mixing of the pesticide solution, the water pump 402 is connected to the storage tank 404 and the spray head 401 via water pipes. One end of the water pipe of the water pump 402 is tightly inserted into the side wall of the storage tank 404 for easy disconnection. The water pump 402 provides power for the pesticide solution transmission, pressurizing the uniformly mixed pesticide solution in the storage tank 404 and then delivering it to the spray head 401 through the water pipes. After receiving the pesticide solution delivered by the water pump 402, the spray head 401 atomizes or sprays the pesticide solution, so that the pesticide solution evenly covers the target crop area, completing the pesticide application operation. After the application of pesticides, loosen the bolts on the connector 505, and pull the plug 602 upwards using the protrusion on the side wall of the plug 602 to disengage it from the connector 505. Then, rotate the connecting shaft 502 to adjust the horizontal position angle of the second support plate 503, flip the support plate 507 hinged to the side wall of the connector 505 so that the brush 508 on one side of the support plate 507 faces upwards. At the same time, engage the clip 509 fixedly installed on the other side of the support plate 507 into the slot 506 at the top of the connector 505 to limit the position of the support plate 507. Continue to rotate the connecting shaft 502 to move the brush 508 below the spray head 401, so that it is aligned with the spray head 401. The bottom contacts the first support plate 501 and connects it to the corresponding connecting groove 510 via bolts on the top of the first support plate 501, thus fixing the angle of the second support plate 503. The motor 504 is started again, and the motor 504 drives the connecting seat 505 to rotate, which in turn drives the support plate 507 and the brush 508 to rotate synchronously. The rotating brush 508 cleans the bottom of the spray head 401, brushing off the pesticide stuck to the spray head and preventing the spray head from being blocked.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
