[0002] A drone is an unmanned aircraft controlled by a radio remote control and its own programmable controller, or operated completely or intermittently autonomously by an onboard computer. With economic development, smart agriculture has emerged, and drones are being used for spraying pesticides on crops.

[0003] At present, in order to improve the flight stability of agricultural drones, most of them install multiple vertical and horizontal plates in the water tank of the agricultural drone to divide the water tank into multiple small spaces and reduce the shaking range of the liquid medicine in the water tank, thereby reducing the inertia generated by the shaking of the liquid medicine and making the flight of the agricultural drone more stable. However, since the vertical and horizontal plates are located inside the water tank, it is more troublesome to clean the inside of the water tank. At the same time, since the water tank and the drone are fixedly connected, the inertia generated by the shaking of the liquid medicine will still directly act on the agricultural drone, making the agricultural drone more difficult to control.

[0032] like Figures 1 to 6As shown, a high-stability agricultural drone includes a drone body 1, a buffer bracket 2 is fixedly installed on the bottom of the drone body 1, an open liquid medicine tank 3 is fixedly installed on the bottom of the buffer bracket 2, a spraying mechanism 4 is fixedly installed on the bottom of the open liquid medicine tank 3, a horizontal plate 5 is fitted on the inner wall of the open liquid medicine tank 3, a plurality of first grooves 6 are provided on the left and right sides of the horizontal plate 5, a right side plate 7 is fixedly installed on the right side of the horizontal plate 5, a first hollow cylinder 8 is fixedly installed on the left side of the right side plate 7, the inner wall of the first hollow cylinder 8 is fitted with the surface of the open liquid medicine tank 3, and vertical plates 9 are fitted on the upper and lower sides of the horizontal plate 5 and the inner wall of the open liquid medicine tank 3, and a plurality of second grooves 6 are provided on the bottom of the vertical plate 9. Groove 10, a left side plate 11 is fixedly installed on the left side of the vertical plate 9, and a second hollow cylinder 12 is fixedly installed on the right side of the left side plate 11. Through the cooperation of the horizontal plate 5 and the vertical plate 9, the interior of the open medicine liquid tank 3 is divided into multiple small spaces. The medicine before and after the vertical plate 9 can flow through the second groove 10, and the medicine above the horizontal plate 5 can flow downward through the first groove 6. When the horizontal plate 5 is inserted into the open medicine liquid tank 3, the horizontal plate 5 is positioned by the first hollow cylinder 8. When the vertical plate 9 is inserted into the open medicine liquid tank 3, the vertical plate 9 is positioned by the second hollow cylinder 12. The inner wall of the second hollow cylinder 12 fits with the surface of the open medicine liquid tank 3, and the left and right sides of the open medicine liquid tank 3 are both openings.

[0033] The left and right sides of the open medicine liquid tank 3, the left side of the right side plate 7, the inner wall of the first hollow cylinder 8, the right side of the left side plate 11 and the inner wall of the second hollow cylinder 12 are all fitted with sealing rings 15. The contact surface between the open medicine liquid tank 3 and the first hollow cylinder 8 can be sealed by the sealing ring 15 between the right side plate 7 and the open medicine liquid tank 3, and the contact surface between the open medicine liquid tank 3 and the second hollow cylinder 12 can be sealed by the sealing ring 15 between the left side plate 11 and the open medicine liquid tank 3. The right side of the right side plate 7 and the left side of the left side plate 11 are fixedly installed with trapezoidal blocks 13, and the front and rear sides of the open medicine liquid tank 3 are fixedly installed with locking mechanisms 14. The inner wall of the locking mechanism 14 fits with the side of the trapezoidal block 13. The front of the open medicine liquid tank 3 is fixedly connected to a liquid adding pipe 16, and the end of the liquid adding pipe 16 away from the open medicine liquid tank 3 is fixedly connected to a valve 17. Liquid can be added to the open medicine liquid tank 3 through the liquid adding pipe 16, and the switch of the liquid adding pipe 16 is controlled by the valve 17.

[0034] Among them, the buffer bracket 2 includes an upper connecting column 201, a support plate 202, a circular hole 203, a steel ball 204, a lower connecting column 205, a baffle 206, a U-shaped plate 207 and an industrial buffer 208. The upper and lower ends of the upper connecting column 201 are fixedly connected to the bottom of the drone body 1 and the upper surface of the support plate 202 respectively. The circular hole 203 is opened in the support plate 202, and the inner wall of the circular hole 203 fits the surface of the steel ball 204. The upper and lower ends of the lower connecting column 205 are respectively fixedly connected to the bottom of the drone body 1 and the upper surface of the support plate 202. The industrial buffer 208 is fixedly connected to the bottom of the steel ball 204 and the upper surface of the open medicine tank 3. The center of the steel ball 204 is on the same vertical line as the axis of the lower connecting column 205. The inner diameter of the circular hole 203 is smaller than the diameter of the steel ball 204. The upper surface of the steel ball 204 fits with the bottom of the baffle 206. The upper surface of the baffle 206 is fixedly connected to the inner wall of the U-shaped plate 207. The upper and lower sides of the industrial buffer 208 are fixedly connected to the inner wall of the support plate 202 and the inner wall of the U-shaped plate 207 respectively.

[0035] It should be noted that when the liquid in the open liquid medicine tank 3 shakes horizontally, the steel ball pushes the baffle 206 upward through the cooperation of the steel ball and the round hole 203, and the industrial buffer 208 is deformed by the upward moving baffle 206. At this time, the deformed industrial buffer 208 offsets the force generated by the liquid medicine during shaking, thereby reducing the influence of the force generated by the liquid medicine during shaking on the drone body 1, thereby making the flight of the agricultural drone more stable.

[0036] like Figures 1 to 7 As shown, the spraying mechanism 4 includes a water pump 401, a solenoid valve 402, a liquid inlet pipe 403, a liquid outlet pipe 404 and a nozzle 405. The upper surface of the water pump 401 is fixedly connected to the bottom of the open liquid tank 3, the liquid inlet end of the water pump 401 is fixedly connected to the liquid outlet end of the solenoid valve 402, the two ends of the liquid inlet pipe 403 are respectively fixedly connected to the bottom of the open liquid tank 3 and the liquid inlet end of the solenoid valve 402, and the two ends of the liquid outlet pipe 404 are respectively fixedly connected to the liquid outlet end of the water pump 401 and the liquid inlet end of the nozzle 405.

[0037] It should be noted that when the water pump 401 and the electromagnetic valve 402 are turned on, the liquid medicine in the open liquid medicine tank 3 is sprayed out through the nozzle 405 by the water pump 401 .

[0038] like Figures 1 to 12 As shown, the locking mechanism 14 includes a connecting block 1401, a hydraulic telescopic rod 1402, a hollow block 1403 and a rectangular ring 1404. The upper and lower ends of the hydraulic telescopic rod 1402 are fixedly connected to the surface of the connecting block 1401 and the surface of the hollow block 1403 respectively. The front and rear sides of the open medicine liquid tank 3 are fixedly connected to the surface of the connecting block 1401. The inner wall of the hollow block 1403 is fixedly connected to the surface of the rectangular ring 1404. The side surface of the trapezoidal block 13 is in contact with the inner wall of the rectangular ring 1404.

[0039] It should be noted that the rectangular ring 1404 can be controlled to move up and down by the hydraulic telescopic rod 1402. At the same time, when the inner wall of the rectangular ring 1404 contacts the side of the trapezoidal block 13, the left side plate 11 and the right side plate 7 can be fixed on the open medicine liquid tank 3 through the cooperation of the rectangular ring 1404 and the trapezoidal block 13, and the vertical plate 9 and the horizontal plate 5 can be fixed in the open medicine liquid tank 3. When the rectangular ring 1404 is separated from the trapezoidal block 13, the vertical plate 9 and the horizontal plate 5 can be directly taken out of the open medicine liquid tank 3.

[0040] The working principle of the present invention is as follows: first, the valve 17 is opened and the medicine liquid is added into the open medicine liquid tank 3 through the liquid adding pipe 16, and the shaking range of the medicine liquid in the open medicine liquid tank 3 is reduced by the cooperation of the vertical plate 9 and the horizontal plate 5 in the open medicine liquid tank 3. When the medicine adding is completed, the valve 17 is closed, and the UAV body 1 is remotely controlled to make the UAV body 1 fly. At the same time, by turning on the water pump 401 and the solenoid valve 402, the medicine liquid in the open medicine liquid tank 3 is sprayed out through the nozzle 405.

[0041] At the same time, when the drone is flying, the support plate 202, the circular hole 203, the steel ball 204, the baffle 206, the U-shaped plate 207 and the industrial buffer 208 cooperate to offset the force generated by the shaking of the liquid medicine in the open liquid medicine tank 3 through the industrial buffer 208.

[0042] When the user needs to clean the inside of the open medicine liquid tank 3, he first separates the rectangular ring 1404 from the trapezoidal block 13 through the hydraulic telescopic rod 1402, and then takes out the vertical plate 9 and the horizontal plate 5 from the open medicine liquid tank 3 respectively. At this time, the open medicine liquid tank 3, the horizontal plate 5 and the vertical plate 9 can be cleaned.

[0043] After cleaning is completed, first insert the horizontal plate 5 into the open medicine liquid tank 3, and put the first hollow cylinder 8 on the open medicine liquid tank 3, then insert the vertical plate 9 into the open medicine liquid tank 3, and put the second hollow cylinder 12 on the open medicine liquid tank 3, and then, use the hydraulic telescopic rod 1402 to reduce the distance between the rectangular ring 1404 and the connecting block 1401, and press the rectangular ring 1404 on the side of the trapezoidal block 13. At this time, through the cooperation of the rectangular ring 1404 and the trapezoidal block 13, the left side plate 11 and the right side plate 7 can be fixed on the open medicine liquid tank 3, and the vertical plate 9 and the horizontal plate 5 can be fixed in the open medicine liquid tank 3.

[0044] The above is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
