Description

Technical Field

[0001] This utility model relates to the field of atomizing spraying technology for drones, and specifically discloses an atomizing spraying device for drones. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. Currently, UAVs are widely used in aerial photography, agriculture, plant protection, miniature selfies, and express delivery, greatly expanding their applications. Developed countries are also actively expanding industry applications and developing UAV technology. In agriculture, UAVs are often used to carry pesticides to spray in fields for pest control and sterilization to improve crop growth rates.

[0003] Most existing drone-based atomizing sprayers use bolts to fix the atomizing nozzles. When a nozzle is damaged or clogged and needs to be disassembled and replaced, the process is cumbersome, affecting replacement efficiency. Repeatedly turning the bolts can strip them, impacting the nozzle's stability. Furthermore, when disassembling the nozzle, the valve on the connecting pipe must be closed to prevent liquid from leaking out and wasting the spray. However, some careless personnel may overlook this, causing liquid to leak out and be wasted. Utility Model Content

[0004] This utility model proposes an atomizing spraying device for drones, which allows for convenient and quick disassembly and installation of the atomizing nozzle, effectively improving the replacement efficiency of the atomizing nozzle. At the same time, it eliminates the need for repeated turning of bolts, avoiding loosening of the atomizing nozzle installation due to bolt stripping, and eliminates the need to close the valve on the pipeline connecting to the atomizing nozzle, automatically sealing the atomizing nozzle installation point to prevent liquid from flowing out through the atomizing nozzle installation point and causing liquid waste.

[0005] This utility model is implemented as follows: a drone atomizing spraying device includes a drone shell and an atomizing nozzle, and an installation mechanism is provided on the lower end face of the drone shell. The mounting mechanism includes a mounting rod fixedly connected to the lower end face of the drone shell. The lower end face of the mounting rod has a mounting groove. The upper end face of the atomizing nozzle is connected to a mounting cylinder that matches the mounting groove. The upper end face of the mounting cylinder is fixedly connected to symmetrically distributed inclined limiting hooks. The lower end of the outer wall of the mounting rod is fixedly connected to two mounting boxes. The lower end face of the mounting box has a notch that matches the inclined limiting hook. The interior of the mounting box is provided with a moving rod. The upper end face of the moving rod has an inclined hole that matches the inclined limiting hook. The mounting rod has a cavity inside, and a sealing ball is installed inside the cavity. The lower end of the cavity is configured with an arc-shaped groove structure that matches the sealing ball, and a through hole is provided at the upper end of the mounting groove.

[0006] In a preferred embodiment of the atomizing spraying device for unmanned aerial vehicles according to this utility model, one end of the movable rod extends to the outside of the mounting box and is fixedly connected to the pull block, and the movable rod is slidably connected to the mounting box.

[0007] In a preferred embodiment of the atomizing spraying device for unmanned aerial vehicles according to this utility model, a retaining ring is fixedly connected to the outer wall of the moving rod, and a return spring sleeved on the outer wall of the moving rod is fixedly connected between the retaining ring and the mounting box.

[0008] As a preferred embodiment of the atomizing spraying device for unmanned aerial vehicles according to this utility model, the upper end of the mounting cylinder is fixedly connected with a plurality of evenly distributed top rods that match the sealing ball.

[0009] As a preferred embodiment of the atomizing spraying device for unmanned aerial vehicles according to this utility model, the upper end of the inner wall of the mounting groove and the lower end of the inner wall of the cavity are both fixedly connected with sealing gaskets that match the mounting cylinder and the sealing ball, respectively.

[0010] As a preferred embodiment of the atomizing spraying device for unmanned aerial vehicles according to this utility model, the outer wall of the mounting rod is fixedly connected with a delivery pipe communicating with the cavity.

[0011] The beneficial effects of this utility model are: By cooperating with the two inclined limit hooks and the two moving rods, the two inclined limit hooks are respectively engaged in the two mounting boxes, and then the atomizing nozzle is installed at the lower end of the mounting rod. By pulling the two moving rods, the engagement between the inclined limit hooks and the moving rods can be released, and then the atomizing nozzle can be pulled off from the lower end of the mounting rod, thus facilitating quick and easy disassembly and installation of the atomizing nozzle and effectively improving the replacement efficiency of the atomizing nozzle. Multiple push rods can lift the sealing ball, allowing the mounting cylinder to connect with the cavity through the through hole. When disassembling the atomizing nozzle, the multiple push rods move out of the cavity, and the sealing ball moves downward by gravity, sealing the through hole. This eliminates the need to close the valve on the pipe connected to the atomizing nozzle, automatically sealing the installation point of the atomizing nozzle to prevent the liquid from flowing out through the installation point and causing waste.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0016] Please see Figure 1-3 A drone atomizing spraying device includes a drone shell 1 and an atomizing nozzle 2, and an installation mechanism is provided on the lower end face of the drone shell 1. The mounting mechanism includes a mounting rod 3 fixedly connected to the lower end face of the drone shell 1. The lower end face of the mounting rod 3 is provided with a mounting groove 4. The upper end face of the atomizing nozzle 2 is connected to a mounting cylinder 5 that matches the mounting groove 4. The upper end face of the mounting cylinder 5 is fixedly connected with symmetrically distributed inclined limit hooks 6. The lower end of the outer wall of the mounting rod 3 is fixedly connected with two mounting boxes 7. The lower end face of the mounting box 7 is provided with a notch 8 that matches the inclined limit hook 6. The interior of the mounting box 7 is provided with a moving rod 9. The upper end face of the moving rod 9 is provided with an inclined hole 10 that matches the inclined limit hook 6. The mounting rod 3 has a cavity 11 inside, and a sealing ball 12 is installed inside the cavity 11. The lower end of the cavity 11 is set with an arc-shaped groove structure that matches the sealing ball 12. The upper end of the mounting groove 4 has a through hole 13.

[0017] In this embodiment: when installing the atomizing nozzle 2, the mounting cylinder 5 is inserted into the mounting groove 4 through the atomizing nozzle 2, so that the mounting cylinder 5 is connected to the through hole 13. At the same time, the two inclined limit hooks 6 enter the mounting box 7 through the two notches 8, and the two inclined limit hooks 6 enter the two inclined holes 10 respectively. Then, through the mutual cooperation between the two inclined limit hooks 6 and the two inclined holes 10, the two moving rods 9 are pushed to move away from the mounting rod 3 until the two inclined limit hooks 6 pass through the two inclined holes 10. Then the two moving rods 9 move in the opposite direction to reset, so that the two inclined limit hooks 6 are respectively engaged with the upper end face of the two moving rods 9, and then the atomizing nozzle 2 is installed at the lower end of the mounting rod 3. At the same time as installing the atomizing nozzle 2, the mounting cylinder 5 drives multiple push rods 17 to enter the cavity 11 through the through hole 13, and pushes up the sealing ball 12, so that the mounting cylinder 5 is connected to the cavity 11 through the through hole 13. When disassembling the atomizing nozzle 2, pull the two moving rods 9 away from the mounting rod 3 to release the engagement between the inclined limit hook 6 and the moving rod 9. Then pull the atomizing nozzle 2 downwards, pulling the mounting cylinder 5 and the two inclined limit hooks 6 out of the mounting groove 4 and the two mounting boxes 7 respectively, thus disassembling the atomizing nozzle 2. Simultaneously, multiple push rods 17 move out of the cavity 11, and the sealing ball 12 moves downwards under gravity, allowing it to enter the lower part of the cavity 11. Within the arc-shaped groove structure, the through hole 13 is sealed by the cooperation between the sealing ball 12 and the lower arc-shaped groove structure inside the cavity 11. This facilitates quick and easy disassembly and installation of the atomizing nozzle 2, effectively improving the replacement efficiency of the atomizing nozzle 2. At the same time, it eliminates the need to repeatedly rotate the bolts, avoiding loosening of the atomizing nozzle 2 due to bolt stripping. Furthermore, it eliminates the need to close the valve on the pipe connecting to the atomizing nozzle 2, automatically sealing the installation point of the atomizing nozzle 2 to prevent the liquid from flowing out through the installation point of the atomizing nozzle 2 and causing liquid waste.

[0018] As a technical optimization of this utility model, one end of the moving rod 9 extends to the outside of the mounting box 7 and is fixedly connected to the pull block 14, and the moving rod 9 is slidably connected to the mounting box 7.

[0019] In this embodiment, the moving rod 9 can be moved by the pull block 14 to facilitate the disassembly of the atomizing nozzle 2.

[0020] As a technical optimization of this utility model, a retaining ring 15 is fixedly connected to the outer wall of the moving rod 9, and a return spring 16 sleeved on the outer wall of the moving rod 9 is fixedly connected between the retaining ring 15 and the mounting box 7.

[0021] In this embodiment: the reset spring 16 and the retaining ring 15 can push the moving rod 9 to move in the opposite direction and reset, so that the two inclined limit hooks 6 are respectively engaged with the upper end face of the two moving rods 9.

[0022] As a technical optimization of this utility model, the upper end of the mounting cylinder 5 is fixedly connected with a plurality of evenly distributed top rods 17 that match the sealing ball 12.

[0023] In this embodiment, multiple push rods 17 can push the sealing ball 12 to move, so that the mounting cylinder 5 can communicate with the cavity 11 through the through hole 13.

[0024] As a technical optimization of this utility model, the upper end of the inner wall of the mounting groove 4 and the lower end of the inner wall of the cavity 11 are both fixedly connected with sealing gaskets 18 that match the mounting cylinder 5 and the sealing ball 12 respectively.

[0025] In this embodiment, two sealing gaskets 18 can seal the mounting groove 4 and the mounting cylinder 5, and the sealing ball 12 and the lower end of the cavity 11.

[0026] As a technical optimization of this utility model, the outer wall of the mounting rod 3 is fixedly connected to a conveying pipe 19 that communicates with the cavity 11.

[0027] In this embodiment, the medicine can be delivered into the cavity 11 through the delivery pipe 19.

[0028] The working principle and usage process of this utility model are as follows: When installing the atomizing nozzle 2, the mounting cylinder 5 is inserted into the mounting groove 4 through the atomizing nozzle 2, so that the mounting cylinder 5 is connected to the through hole 13. At the same time, the two inclined limit hooks 6 enter the mounting box 7 through the two notches 8, and the two inclined limit hooks 6 respectively enter the two inclined holes 10. Then, through the mutual cooperation between the two inclined limit hooks 6 and the two inclined holes 10, the two moving rods 9 are pushed to move away from the mounting rod 3 until the two inclined limit hooks 6 pass through the two inclined holes 10. Then, the two moving rods 9 are pushed to move in the opposite direction to reset through the return spring 16 and the retaining ring 15, so that the two inclined limit hooks 6 are respectively engaged with the upper end face of the two moving rods 9, and then the atomizing nozzle 2 is installed at the lower end of the mounting rod 3. At the same time as installing the atomizing nozzle 2, the mounting cylinder 5 drives multiple push rods 17 to enter the cavity 11 through the through hole 13, and pushes up the sealing ball 12, so that the mounting cylinder 5 is connected to the cavity 11 through the through hole 13. When disassembling the atomizing nozzle 2, pull the two moving rods 9 away from the mounting rod 3 to release the engagement between the inclined limit hook 6 and the moving rod 9. Then pull the atomizing nozzle 2 downward to pull the mounting cylinder 5 and the two inclined limit hooks 6 out of the mounting groove 4 and the two mounting boxes 7 respectively, thereby disassembling the atomizing nozzle 2. At the same time as disassembling the atomizing nozzle 2, multiple push rods 17 are moved out of the cavity 11. Simultaneously, the sealing ball 12 moves downward by gravity, allowing the sealing ball 12 to enter the arc-shaped groove structure at the lower end of the cavity 11. Then, through the mutual cooperation between the sealing ball 12 and the arc-shaped groove structure at the lower end of the cavity 11, the through hole 13 is sealed. In use, the liquid medicine is delivered into the cavity 11 through the delivery pipe 19, and then the liquid medicine enters the atomizing nozzle 2 through the through hole 13 and the mounting cylinder 5, and is then atomized and sprayed out through the atomizing nozzle 2.
