Description

Technical Field

[0001] This utility model belongs to the field of pesticide spraying technology, and in particular relates to a drone pesticide spraying device. Background Technology

[0002] In agricultural production, drone-based pesticide spraying devices have been widely used due to their high efficiency and convenience. However, existing drone-based pesticide spraying devices face some problems that urgently need to be addressed in practical applications.

[0003] On the one hand, in existing drone pesticide spraying devices, the water tank is mostly fixedly installed. This installation method makes disassembly cumbersome when the water tank malfunctions or requires cleaning and maintenance. Workers find it difficult to easily remove the tank from the device, hindering comprehensive inspection, repair, or cleaning of the tank's interior, thus affecting its normal use and leading to unstable performance of the entire spraying device. On the other hand, in existing devices, the diversion pipe is prone to shaking or displacement during drone flight and spraying. Due to the lack of a stable support structure, this shaking or displacement may cause loose pipe connections, leading to pesticide leakage and other problems, seriously affecting the stable operation of the spraying system.

[0004] To address these issues, we provide a drone-based pesticide spraying device. Utility Model Content

[0042] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7 This utility model is a pesticide spraying device for drones, including a drone body 1, with connecting frames 2 fixed at both ends of the drone body 1; an installation strip 3 is fixed at one end of the connecting frame 2, and an installation plate 4 is fixed on one side of the installation strip 3; installation grooves 5 are opened on both sides of the installation strip 3; a fixed shell 6 is slidably connected to the outside of the installation strip 3, and a bracket 7 is fixed between the two fixed shells 6, with a water storage tank 8 fixed in the center of the bracket 7; a connecting rod 9 is fixed at the bottom of the fixed shell 6, and a water pump 10 is fixed at one end of the connecting rod 9; the output end of the water pump 10 is connected to a connecting pipe 11 through a first water pipe, and a plurality of diversion pipes 12 are fixed at one end of the connecting pipe 11; a plurality of nozzles 13 are fixed at the bottom of the diversion pipes 12, and a reinforcing rod 14 is fixed between one side of the connecting pipe 11 and the fixed shell 6.

[0043] Specifically, the water storage tank 8 has a water inlet 15 at the top; the input end of the water pump 10 is fixedly connected to the water storage tank 8 through a second water pipe; limit strips 16 are fixed on both sides of the inner wall of the fixed shell 6, and the limit strips 16 are slidably connected to the inner wall of the mounting groove 5.

[0044] Furthermore, a fixing plate 17 is fixed to one end of the fixing shell 6, and both the fixing plate 17 and the mounting strip 3 have a first threaded hole 18 at one end.

[0045] The operation process of this embodiment is as follows: Before use, an appropriate amount of medicine is poured into the water tank 8 through the water inlet 15 at the top of the water tank 8. Then, the fixing shell 6 is slid along the outside of the mounting strip 3 so that the limiting strip 16 on the inner wall of the fixing shell 6 is aligned and engaged with the mounting grooves 5 on both sides of the mounting strip 3, ensuring that the fixing shell 6 can slide and adjust its position along the mounting strip 3. After sliding to a suitable position, the fixing shell 6 is fixed to the mounting strip 3 with screws through the first threaded hole 18 at one end of the fixing plate 17 and the mounting strip 3, thereby stably installing the water tank 8 below the drone body 1. The drone body 1 is started, and after it rises to a suitable height, the water pump 10 is turned on. The water pump 10 is circulated. The chemical solution is drawn from the water storage tank 8 through the second water pipe, transported to the connecting pipe 11 through the first water pipe, and then distributed through the diversion pipe 12. Finally, it is evenly sprayed onto the target area by the nozzle 13 at the bottom. During the spraying process, the reinforcing rod 14 can enhance the structural strength between the connecting pipe 11 and the fixed shell 6, ensuring the stable operation of the spraying system. By setting the fixed shell 6 and the mounting strip 3, when the water storage tank 8 malfunctions or needs cleaning and maintenance, this flexible disassembly and installation design allows the staff to easily remove it from the device, facilitating a comprehensive inspection, repair, or cleaning of the inside of the water storage tank 8, ensuring the normal use of the water storage tank 8, and thus ensuring the working performance of the entire spraying device.

[0046] For a specific embodiment two, please refer to Figure 5-7 Based on the first specific embodiment, a support block 19 is fixed to the top of the diversion pipe 12, and several support plates 20 are fixed to one side of the mounting plate 4; a placement groove 21 is opened on the upper surface of the support plate 20; a placement plate 22 is movably connected inside the placement groove 21, a support rod 23 is fixed to one end of the placement plate 22, and a reinforcing block 24 is fixed to the end of the support rod 23 away from the placement plate 22; a second threaded hole 25 is opened on the surface of both the reinforcing block 24 and the support block 19, and a third threaded hole 26 is opened on the surface of both the support plate 20 and the placement plate 22.

[0047] Specifically, an extension plate 27 is fixed to the top of the mounting plate 4, and a fixing rod 28 is fixed to one side of the extension plate 27; a buffer frame 29 is fixed to one end of the fixing rod 28.

[0048] Furthermore, several tension springs 30 are fixed inside the buffer frame 29; an adjusting plate 31 is fixed to one end of the tension spring 30, and a buffer rod 32 is fixed to one end of the adjusting plate 31; the buffer rod 32 passes through the bottom of the buffer frame 29, and a buffer plate 33 is fixed to the end of the buffer rod 32 away from the adjusting plate 31.

[0049] The operation process of this embodiment is as follows: The placement plate 22 is inserted into the placement groove 21 of the support plate 20, so that the reinforcing block 24 at one end of the support rod 23 fits against the support block 19 at the top of the diversion pipe 12, and is fixed with screws through the second threaded holes 25 of both; simultaneously, the support plate 20 and the placement plate 22 are further fixed with screws through the third threaded holes 26 on their surfaces. One end of the support rod 23 is connected to the support plate 20 through the placement plate 22, and the other end is fixed to the support block 19 at the top of the diversion pipe 12 through the reinforcing block 24, forming a stable support structure. This can... This effectively reduces the shaking or displacement of the diversion pipe 12 during the flight and spraying process of the UAV body 1, avoiding problems such as loose connections and pesticide leakage caused by pipe shaking, and ensuring the stable operation of the spraying system. When the UAV body 1 lands after completing the spraying operation, the bottom buffer plate 33 contacts the ground first. At this time, the tension spring 30 inside the buffer frame 29 is compressed and contracted. Through the linkage of the adjusting plate 31 and the buffer rod 32, the impact force during landing is absorbed, reducing the vibration of the UAV body 1 and playing a buffer protection role to prevent the equipment from being damaged by the landing impact.
