Description

Technical Field

[0001] This utility model relates to the technical field of pesticide spraying devices for unmanned aerial vehicles (UAVs), specifically a pesticide spraying device for agricultural UAVs. Background Technology

[0002] Agricultural drones are unmanned aerial vehicles used in agriculture. They are typically equipped with pesticide spraying devices, seeding devices, monitoring equipment, etc., and can fly autonomously over farmland according to preset routes and parameters to perform a variety of agricultural operations such as pesticide spraying, seed sowing, and monitoring crop growth. They are characterized by high efficiency, precision, and flexibility, and can effectively improve agricultural production efficiency and reduce labor intensity and production costs.

[0003] Agricultural drones require a spraying mechanism, such as a pesticide tank, for pesticide spraying. A search revealed Chinese patent application CN201620686681.6, which describes a pesticide spraying tank for drones. The tank includes a shell, a cover on the shell, and first and second handles symmetrically located on either side of the cover. The shell is hollow and includes a first surface, a second surface parallel to the first surface, and a side surface connecting the first and second surfaces. The second surface includes an inner side and an outer side near the first surface. The inner side has an inclined surface connected to the side surface and a plane at the bottom of the inclined surface, forming a "V" shape. Because of the "V" shape in the shell, the pesticide residue in the above-mentioned drone pesticide spraying tank is less likely to remain.

[0004] The above technical solutions still have shortcomings, such as the lack of a mixing mechanism, which cannot effectively prevent pesticide precipitation and stratification. During long-term flight, pesticide precipitation will cause uneven pesticide concentration sprayed from the nozzle, affecting the spraying effect and may even clog the nozzle. Utility Model Content

[0005] The purpose of this invention is to provide a pesticide spraying device for agricultural drones, which reduces the possibility of nozzles being clogged by sediment and impurities, reduces the frequency of nozzle maintenance and cleaning, ensures that the spraying device can work continuously and stably, improves the efficiency of agricultural operations, and also reduces equipment maintenance costs, thereby solving the problems mentioned in the background art.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A pesticide spraying device for agricultural drones, comprising:

[0029] A container 1 for storing pesticides; a filling port 2 connected to the inner cavity is provided on one side of the top of the container 1, and a sealing plug is installed on the filling port 2; a pesticide outlet 16 is provided at the bottom of the container 1, and a gear pump 17 and a nozzle 18 are installed at the lower end of the pesticide outlet 16 for spraying the pesticide solution in the container 1; a rim 3 is provided on the outer wall of the container 1, and a mounting device for hanging on a drone is provided on the rim 3.

[0030] The box 1 serves as a container for storing pesticides. The top filling port 2 is used to add pesticides. After adding, the port is sealed with a sealing plug to prevent pesticide leakage. The bottom outlet 16 uses a gear pump 17 to extract the pesticides from the box 1 and spray them out through the nozzle 18. The mounting parts on the side 3 are used to securely hang the entire device on the drone, enabling the drone to carry it for agricultural spraying operations.

[0031] Please see Figure 1-2 :

[0032] It also includes a mixing mechanism for mixing the liquid medicine inside the box 1; the mixing mechanism includes a top cover 4 and a motor 5. The top cover 4 is installed on the top of the box 1 by fixing screws, the motor 5 is installed on the top cover 4, and a shaft 19 driven by the motor 5 is rotatably installed at the bottom of the top cover 4. Multiple sets of stirring rods 20 are distributed on the outer wall of the shaft 19.

[0033] Furthermore, the top of the housing 1 has a first notch 6, and the bottom of the top cover 4 has a sealing ring that is inserted into the first notch 6. A fixing screw hole 7 is provided around the first notch 6 on the top of the housing 1, and a protrusion 8 is provided around the edge of the top cover 4. A first through hole 9 is provided on the protrusion 8, and the fixing screw is threaded into the fixing screw hole 7 through the first through hole 9. This facilitates the removal of the top cover 4 for maintenance of the mixing mechanism and cleaning of the interior of the housing 1.

[0034] The top cover 4 is connected to the top of the box 1 by fixing screws. The motor 5 is installed on the top cover 4. After the motor 5 is started, the motor 5 drives the shaft 19 to rotate at the bottom of the top cover 4. Multiple sets of stirring rods 20 distributed on the outer wall of the shaft 19 rotate with the shaft 19 to stir and mix the pesticide in the box 1. In addition, the sealing ring at the bottom of the top cover 4 is inserted into the first notch 6 at the top of the box 1 to enhance the sealing of the connection. The design of the fixing screw hole 7 and the first through hole 9 on the protrusion 8 makes it easy to fix the top cover 4 to the box 1 tightly with fixing screws. When it is necessary to maintain the mixing mechanism or clean the inner cavity of the box 1, the top cover 4 can be removed by unscrewing the fixing screws.

[0035] In summary, this design solves the problem of traditional devices lacking a mixing mechanism, effectively preventing pesticide sedimentation and stratification, ensuring that pesticides remain uniform during flight, and improving the spraying effect. At the same time, the removable top cover design facilitates equipment maintenance and cleaning, and extends the service life of the equipment.

[0036] Please see Figure 3-4 :

[0037] It also includes a filtration mechanism disposed within the inner cavity of the housing 1. The filtration mechanism includes a partition 10 and a filter basket 13. The partition 10 divides the inner cavity of the housing 1 into an upper inner cavity and a lower inner cavity. The shaft 19 is located inside the upper inner cavity, and the filter basket 13 is mounted on the partition 10. A second notch 11 is provided on the partition 10, and the filter basket 13 is inserted into the inside of the second notch 11. A filter screen 14 is provided at the bottom of the filter basket 13 to filter impurities and particles in the liquid medicine and prevent the nozzle 18 from becoming clogged.

[0038] Furthermore, a second through hole 15 is provided on the upper edge of the filter basket 13, and threaded posts 12 are arranged around the second notch 11 on the partition plate 10. The threaded posts 12 pass through the second through hole 15 and engage with nuts to lock and fix the filter basket 13. The filter basket 13 can be removed from the second notch 11 and taken out from the first notch 6 by removing the nuts.

[0039] The partition 10 divides the inner cavity of the box 1 into an upper inner cavity and a lower inner cavity. The shaft 19 is located in the upper inner cavity and drives the pesticide flow in the upper inner cavity during stirring. The filter basket 13 is installed at the second notch 11 of the partition 10 and is fixed by the threaded post 12 and nut. As the pesticide flows from the upper part of the box 1 to the lower outlet 16, it first passes through the filter screen 14 at the bottom of the filter basket 13. Impurities and particles in the pesticide solution are intercepted by the filter screen 14, thereby preventing the nozzle 18 from clogging. When it is necessary to clean the filter basket 13, the nut is removed, and the filter basket 13 can be taken out from the second notch 11 and then taken out through the first notch 6 at the top of the box 1 for cleaning.

[0040] In summary, the filtration mechanism can filter impurities and particles in pesticides, further ensuring the normal operation of the nozzle 18, reducing the risk of nozzle 18 clogging, ensuring the continuity and stability of pesticide spraying, and allowing for easy disassembly of the filter basket 13 for cleaning and maintenance.
