Description

Technical Field

[0001] This application relates to the technical field of drone spraying booms, and more particularly to an agricultural drone spraying boom. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated completely or intermittently autonomously by onboard computers. When used in agriculture, agricultural UAVs can carry out pesticide spraying operations on agricultural crops by carrying accessories such as pesticide tanks and spraying booms.

[0003] A search revealed Chinese Patent Publication No. CN221228557U, which discloses a spraying rod for agricultural drones. The rod includes a spraying rod body, a connector, and a nozzle. The connector is installed at the short end of the spraying rod body, and the nozzle is installed at the long end. The rod also includes a rotating ring A, a rotating ring B, a sealing cylinder, a connecting pipe, a cap, a core rod, a stop plate, a sealing ring, and a scraping disc. The long end of the spraying rod body is fixed with rotating ring A and rotating ring B respectively. By improving the spraying rod body for agricultural drones, water-permeable openings are provided at both ends of the long end of the spraying rod body. These openings are connected to the externally sealed connecting pipe and sealing cylinder. After the connecting pipe is detached from rotating ring B of the spraying rod body, the core rod connected to the cap, along with the scraping disc, can reciprocate to scrape the inner cavity of the spraying rod body. Water can also be flushed into the spraying rod body from rotating ring A for rinsing, ensuring that the spraying rod body can be cleaned easily and cleanly after use.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The above-mentioned solution improves the spray bar body used in agricultural drones by providing water-permeable openings at both ends of the long rod body. These openings are connected to an externally sealed connecting pipe and a sealing sleeve. After the connecting pipe is detached from the rotating ring B of the spray bar body, the core rod connected to the sealing cap, carrying a scraping disc, can repeatedly scrape the inner cavity of the spray bar body. Water can also be flushed into the spray bar body from the rotating ring A for rinsing, ensuring the spray bar body can be cleaned relatively easily after use. However, this device cannot quickly install the rod body and connecting frame. The length of the spray bar needs to be adjusted according to the spraying range. While the length of the spray bar can be adjusted by setting up easily detachable rod bodies and connecting frames, the inability to quickly detach the rod body and connecting frame results in a smaller spraying range. Changing to different spray bars according to usage needs also leads to inconvenience. Utility Model Content

[0005] In order to enable quick assembly and disassembly of the pole and the connecting frame, this application provides an agricultural drone spraying pole.

[0006] This application provides an agricultural drone spraying boom, which adopts the following technical solution: it includes several booms and several connecting frames. Each boom has an elastic plate fixedly connected to its outer surface. The outer surface of each elastic plate engages with a corresponding connecting frame. Each boom has a slot on its outer surface. Each connecting frame has a pressure plate rotatably connected to its outer surface. A second spring is fixedly connected to the inner wall of each pressure plate. A push rod is fixedly connected to the other end of each second spring. The outer surface of each push rod is slidably connected to a corresponding pressure plate. The outer surface of each push rod is inserted into a corresponding connecting frame. A fixing post is fixedly connected to the outer surface of each connecting frame. An insert rod is slidably connected to the inner wall of each fixing post. The outer surface of each insert rod is inserted into a corresponding slot.

[0007] Optionally, a first spring is fitted onto the outer surface of each of the insertion rods, with the top end of each first spring fixedly connected to the corresponding insertion rod and the other end fixedly connected to the corresponding fixing post.

[0008] Optionally, two locking blocks are fixedly connected to the outer surface of each rod, and the outer surface of each locking block is engaged with a corresponding fixing post. A connecting pipe is fixedly connected to the inner wall of one of the rods, and a connector is fixedly connected to the end of the connecting pipe away from the corresponding rod. A spraying pipe is fixedly connected to the outer surface of each rod.

[0009] Optionally, the outer surface of each rod is inserted into a corresponding connecting frame, and the inner wall of each connecting frame has two placement slots, and the inner wall of each placement slot is fitted with a second waterproof gasket.

[0010] Optionally, each of the two rods has a fixed cap threaded to the end away from the connecting tube, and a first waterproof gasket is snapped into the inner wall of each fixed cap.

[0011] Optionally, a fixing frame is fixedly connected to the outer surface of each connecting frame, a bidirectional screw is rotatably connected to the inner wall of each fixing frame, and a rotating wheel is fixedly connected to one end of each bidirectional screw.

[0012] Optionally, each of the bidirectional screws has two clamping plates threadedly connected to its outer surface, and the outer surface of each clamping plate is slidably connected to the corresponding fixing frame.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model comprises components such as a rod, connecting frame, insert rod, second spring, elastic retaining plate, push rod, pressure plate, and fixing column. By inserting the rod into the corresponding connecting frame, the elastic retaining plate engages with the corresponding connecting frame. Then, rotating the pressure plate and pushing the push rod compresses the corresponding second spring until the pressure plate completely covers the corresponding elastic retaining plate. At this point, releasing the push rod allows the second spring to re-enter the corresponding connecting frame under its restoring force. The insertion of the insert rod into the corresponding slot reinforces the connection between the rod and the connecting frame, thus achieving the effect of quick assembly and disassembly of the rod and connecting frame through the cooperation of the elastic retaining plate and the insert rod.

[0015] 2. This utility model incorporates components such as a bidirectional screw, a rotating wheel, clamping plates, and a fixing frame. By rotating the rotating wheel, the bidirectional screw is driven to rotate. The rotation of the bidirectional screw causes the two corresponding clamping plates to move simultaneously along the bidirectional screw in opposite directions. This allows the clamping plates to clamp the drone, thus achieving the effect of quickly clamping and fixing drones of different sizes by adjusting the clamping plates. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0022] This application discloses an agricultural drone spraying boom. For example... Figure 1 , Figure 2 , Figure 3As shown, the device includes several rods 1 and several connecting frames 7. Each rod 1 has two locking blocks 22 fixedly connected to its outer surface. The outer surface of each locking block 22 is engaged with a corresponding fixed post 13. A connecting pipe 2 is fixedly connected to the inner wall of one of the rods 1. A connector 3 is fixedly connected to the end of the connecting pipe 2 away from the corresponding rod 1. A spraying pipe 8 is fixedly connected to the outer surface of each rod 1. The spraying rod can be extended by inserting the rod 1 into the adjacent connecting frame 7, and different numbers of rods 1 can be connected as needed. When the connecting frame 7 is connected to the rod 1, the locking block 22 will engage with the corresponding fixed post 13. At this time, the fixed post 13 will be fixed to the rod 1. The connecting pipe 2 and the connector 3 allow the connector 3 to be connected to the water inlet pipe, and the sprayed medicine can be delivered into the rod 1 through the connecting pipe 2.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Each rod 1 has an elastic plate 4 fixedly connected to its outer surface. The outer surface of each elastic plate 4 is engaged with the corresponding connecting frame 7. The outer surface of each connecting frame 7 is fixedly connected with a fixing frame 9. During the process of connecting the rod 1 and the connecting frame 7, the elastic plate 4 will engage with the corresponding connecting frame 7. Therefore, the rod 1 and the connecting frame 7 can be quickly fixed by the elastic plate 4.

[0024] Please see Figure 3 , Figure 4 Each mounting bracket 9 has a bidirectional screw 20 rotatably connected to its inner wall. A rotating wheel 19 is fixedly connected to one end of each bidirectional screw 20. Two clamping plates 21 are threadedly connected to the outer surface of each bidirectional screw 20. The outer surface of each clamping plate 21 is slidably connected to the corresponding mounting bracket 9. Rotating the rotating wheel 19 causes the corresponding bidirectional screw 20 to rotate. The rotation of the bidirectional screw 20 causes the two clamping plates 21 to move simultaneously along the bidirectional screw 20 in opposite directions. This movement of the clamping plates 21 clamps the drone, facilitating the installation of the spray boom on drones of different sizes.

[0025] Please see Figure 4Each rod 1 has a slot 12 on its outer surface, and each connecting frame 7 has a pressure plate 16 rotatably connected to its outer surface. Each pressure plate 16 has a second spring 17 fixedly connected to its inner wall, and each second spring 17 has a push rod 18 fixedly connected to its other end. The outer surface of each push rod 18 is slidably connected to the corresponding pressure plate 16, and the outer surface of each push rod 18 is inserted into the corresponding connecting frame 7. When the elastic plate 4 is snapped onto the corresponding connecting frame 7, the pressure plate 16 is rotated, and the pressure plate 16 will rotate around the corresponding connecting frame 7 until the pressure plate 16 presses onto the corresponding elastic plate 4. During this process, the push rod 18 is pushed to slide along the corresponding pressure plate 16 until the pressure plate 16 is completely pressed onto the corresponding elastic plate 4. At this time, the push rod 18 is released, and the second spring 17 will push the corresponding push rod 18 to reset and insert into the corresponding connecting frame 7 under its rebound force, thereby preventing the elastic plate 4 from dislodging.

[0026] Please see Figure 3 Each connecting frame 7 has a fixed post 13 fixedly connected to its outer surface. Each fixed post 13 has a sliding rod 14 slidably connected to its inner wall. Each rod 14 has a first spring 15 sleeved on its outer surface. The top end of each first spring 15 is fixedly connected to the corresponding rod 14, and the other end is fixedly connected to the corresponding fixed post 13. Each rod 14 is inserted into the corresponding slot 12. By pulling the rod 14 to make it slide vertically along the corresponding fixed post 13, the first spring 15 will be compressed until the rod 14 and the corresponding slot 12 are on the same central axis. At this time, the rod 14 is released, and the first spring 15 will push the corresponding rod 14 into the corresponding slot 12 under its rebound force, thereby enhancing the connection between the rod 1 and the connecting frame 7.

[0027] Please see Figure 2 Each rod 1 has its outer surface inserted into a corresponding connecting frame 7. Each connecting frame 7 has two placement slots 11 on its inner wall. Each placement slot 11 has a second waterproof gasket 10 snapped into its inner wall. The ends of the two rods 1 away from the connecting pipe 2 are threaded with a fixing cap 5. Each fixing cap 5 has a first waterproof gasket 6 snapped into its inner wall. Specifically, by placing the second waterproof gasket 10 in the corresponding placement slot 11, the gap between the rod 1 and the corresponding connecting frame 7 can be waterproofed. Then, by placing the first waterproof gasket 6 in the corresponding fixing cap 5, and then installing the fixing cap 5 and the corresponding rod 1, the rod 1 can be sealed.

[0028] The implementation principle of an agricultural drone spraying boom according to this application embodiment is as follows: First, select different numbers of booms 1 and connecting frames 7 as needed. Then, insert booms 1 into the corresponding connecting frames 7. During this process, the insertion rod 14 needs to be pulled so that it slides vertically along the corresponding fixed post 13. The first spring 15 will be compressed. Then, when the boom 1 is fully inserted into the corresponding connecting frame 7, the elastic plate 4 will engage with the corresponding connecting frame 7. At this time, the insertion rod 14 will be on the same central axis as the corresponding slot 12. Then, release the insertion rod 14. The first spring 15 will push the corresponding insertion rod 14 into the corresponding slot 12 under its rebound force. Then, rotate the pressure plate 16 to press it onto the corresponding elastic plate 4. During this process... In the process, push rod 18 needs to be pushed to compress the second spring 17 until the pressure plate 16 is completely pressed on the corresponding elastic plate 4. Then, release the second spring 17. Under its rebound force, the second spring 17 will push the corresponding push rod 18 to reset and insert into the corresponding connecting frame 7, thereby reinforcing the elastic plate 4. Finally, place the first waterproof gasket 6 into the corresponding fixing cover 5, and then install and seal the rod body 1 with the fixing cover 5. Then, rotate the rotating wheel 19 to drive the corresponding bidirectional screw 20 to rotate. The rotation of the bidirectional screw 20 will drive the corresponding clamping plate 21 to clamp the drone. Finally, by connecting the connector 3 to the water pipe, the liquid medicine can be delivered into the spraying rod and sprayed out through the spraying pipe 8.

[0029] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
