[0002] A drone, or unmanned aerial vehicle, is an aircraft capable of autonomous flight without direct pilot control. It relies on pre-programmed flight control systems and remote monitoring from ground stations to perform its missions. It is widely used in military reconnaissance, target strikes, logistics and transportation, agricultural plant protection, geographic mapping, environmental monitoring, and other fields. The plant protection pesticide spraying drone is an intelligent agricultural device that integrates modern aviation technology, information technology, and precision spraying technology. Designed specifically for farmland pest control, fertilization, and field management, it uses an advanced flight control system to achieve autonomous flight and precisely spray pesticides, fertilizers, and other plant protection chemicals over farmland. This significantly improves agricultural production efficiency, reduces labor costs, and minimizes chemical usage and environmental impact through precision spraying technology.

The left screw 7 and the right screw 7 have opposite thread rotation directions. The other ends of the screws 7 are connected to the bottom of the body 1 through bearings, and the surfaces of the screws 7 are connected to clamping rods 8 through threads.

[0024] The above solution is adopted: by providing a double-headed motor 6, the positions of the clamping rod 8 and the support plate 10 can be automatically adjusted, so that adaptive adjustments can be made according to containers of different sizes, thereby enhancing the flexibility and applicability of the equipment.

[0025] refer to Figure 2 The four corners of the bottom of the body 1 are provided with connection holes 9, and the inside of the connection holes 9 are connected with card rods 8 by sliding. The front and rear sides of the bottom of the card rod 8 are fixedly connected with support plates 10. The support plates 10 on both sides cooperate with each other. The top of the support plate 10 is placed on the water tank 11, and the shape of the top of the support plate 10 corresponds to the shape of the bottom of the water tank 11.

[0026] The above solution is adopted: by providing the support plate 10, it is convenient for users to install and maintain the water tank 11. Such a design also allows users to replace different containers according to actual needs, thereby increasing the versatility and flexibility of the equipment.

[0027] refer to Figure 3 The top of the front support plate 10 is provided with a slide groove 12, and the inside of the slide groove 12 is connected to the limit plate 13 through sliding. A number of accommodating grooves 14 are provided at the bottom of the slide groove 12, and a number of pushing grooves 15 are provided on the top of the limit plate 13. The pushing grooves 15 are equidistantly distributed on the top of the limit plate 13.

[0028] The above solution is adopted: by setting a limit plate 13, the gear rod 17 can be blocked by sliding the limit plate 13, thereby limiting the gear rod 17 from extending out of the accommodating groove 14, thereby preventing the gear rod 17 from extending out to block the water tank 11 when the water tank 11 is installed on the support plate 10.

[0029] refer to Figure 4 A spring 16 is placed inside the accommodating groove 14, and a shift rod 17 is placed inside the spring 16. The surface of the shift rod 17 is connected to the inside of the spring 16 by sleeve arrangement. The top of the shift rod 17 passes through and extends out of the top of the slide groove 12, and the bottom of the shift rod 17 passes through the bottom of the support plate 10.

[0030] With the above solution, by providing the shift lever 17 and the spring 16 , the position of the water tank 11 can be restricted through the coordinated use of the shift lever 17 and the spring 16 , thereby preventing the water tank 11 from being shifted during use.

[0031] refer to Figure 3 The bottom of each gear lever 17 is fixedly connected with a pulling handle 18 , and every two gear levers 17 share the same pulling handle 18 .

[0033] refer to Figure 3 A number of anti-slip grooves 19 are provided on the top of the support plate 10 , and the anti-slip grooves 19 are evenly distributed on the top of the support plate 10 .

[0034] The above solution is adopted: by providing the anti-slip grooves 19, the friction coefficient of the contact surface can be increased, effectively preventing the water tank 11 from sliding due to vibration or external force during the operation of the equipment, thereby ensuring the safety and reliability of the equipment operation.

[0035] The working principle of this utility model:

[0036] When in use, first place the device on the ground, then pull the handle 18 downward to retract the gear rod 17 to the bottom of the chute 12, then push the limit plate 13 along the chute 12 to the top of the gear rod 17 to limit the extension of the gear rod 17, then place the water tank 11 on the top of the support plate 10, the top of the support plate 10 is provided with anti-slip grooves 19, which increase the friction and prevent the water tank 11 from sliding, then start the double-headed motor 6, because the screw 7 connected to the output ends of the double-headed motor 6 has opposite threads, The clamping rods 8 and the support plates 10 on both sides move in opposite directions to clamp the left and right sides of the water tank 11. After the water tank 11 is fixed, the limit plate 13 is pushed open. At this time, the spring 16 resets to move the gear lever 17 upward, thereby limiting the position of the front side of the water tank 11. Then start the water pump 2, extract the liquid through the two water suction ports 4 at the bottom of the water pump 2, and transport it to the nozzles 3 fixed around the bottom of the body 1 to achieve uniform spraying, and then start the body 1 to spray the target with medicine.

It usually requires a series of complex steps to complete disassembly and installation. The operation is cumbersome and time-consuming, which increases labor intensity and reduces work efficiency. In addition, due to the insufficient fixing method, the water tank may be displaced or vibrated during the operation of the equipment, affecting the stability and accuracy of the spraying operation.
