Description

Technical Field

[0001] This utility model belongs to the field of drone fertilization technology, and in particular relates to a drone fertilizer spraying and dispensing mechanism. Background Technology

[0002] Traditional fertilizer application methods mainly rely on manual labor or ground machinery, which have many limitations. Manual fertilization is not only labor-intensive and inefficient, but also struggles to ensure uniformity and precision, easily leading to fertilizer waste and environmental pollution. While ground machinery fertilization improves efficiency to some extent, it is greatly limited by terrain, making it difficult to operate in complex terrain or steep slopes. Against this backdrop, drone fertilizer spraying technology has been widely used in agricultural production due to its high efficiency and operational flexibility. However, existing drone fertilizer spraying and dispensing mechanisms still have some problems in practical use.

[0003] Many existing facilities lack effective filtration devices in their water storage tanks, or have poorly designed filtration structures. When spraying fertilizer solutions containing solid particles and impurities, these impurities easily enter the nozzles with the solution, causing nozzle blockage. This not only affects the uniformity of spraying but also requires frequent shutdowns for nozzle cleaning, severely reducing operational efficiency. Furthermore, in some facilities with filtration functions, the filter components are often fixed in place, making disassembly and cleaning cumbersome. Over time, the filtration effect decreases, further exacerbating the nozzle blockage problem.

[0004] To address these issues, we provide a drone-based fertilizer spraying and dispensing mechanism. Utility Model Content

[0005] The purpose of this invention is to provide a fertilizer spraying and dispensing mechanism for unmanned aerial vehicles (UAVs). Through the action of a filter screen, the filter screen can filter the liquid in the water tank, removing solid particles and impurities from the liquid, preventing impurities from clogging the nozzle, ensuring the smooth flow of the nozzle, and ensuring that the liquid passes smoothly through the nozzle for uniform spraying. This solves the problem that when spraying fertilizer solutions containing solid particles and impurities, the impurities easily enter the nozzle with the solution, causing nozzle clogging, which not only affects the uniformity of spraying, but also requires frequent shutdowns to clean the nozzle.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a drone fertilizer spraying and dispensing mechanism, including a drone body, and a connecting rod is fixed at the bottom of the drone body;

[0042] For a specific implementation example, please refer to Implementation Example 1. Figure 1-10This utility model is a fertilizer spraying and dispensing mechanism for unmanned aerial vehicles (UAVs), including a UAV body 1, with a connecting rod 2 fixed to the bottom of the UAV body 1; a mounting plate 3 is fixed to one end of the connecting rod 2, and a mounting groove 4 is opened on the surface of the mounting plate 3; a mounting strip 5 is slidably connected inside the mounting groove 4, and a fixing shell 6 is fixed to one side of the mounting strip 5, with a water storage tank 7 fixed inside the fixing shell 6; positioning strips 8 are fixed to both sides of the inner wall of the water storage tank 7, and a sliding strip 9 is slidably connected inside the positioning strip 8; a filter plate 10 is fixed to one side of the sliding strip 9, and a filter screen 11 is fixed to the center of the filter plate 10; a positioning hole 12 is opened on the outside of the water storage tank 7, and a tension spring 13 is fixed to one side of the positioning hole 12, with a handle 14 fixed to one end of the tension spring 13; a locking rod 15 is fixed to one end of the handle 14, and the locking rod 15 passes through the positioning hole 12; a limit hole 16 is opened on one side of the sliding strip 9, and one end of the locking rod 15 is inserted into the limit hole 16.

[0043] Specifically, the slider 9 has a "T" shaped structure, and the inner wall of the positioning strip 8 matches the slider 9.

[0044] Furthermore, a water pump 17 is fixed on one side of the water storage tank 7, and the input end of the water pump 17 is fixedly connected to the water storage tank 7 through a first water pipe; a diversion pipe 18 is fixed to the output end of the water pump 17 through a second water pipe, and several nozzles 19 are fixed on one side of the diversion pipe 18; a support rod 20 is connected between the diversion pipe 18 and the fixed shell 6.

[0045] The operation process of this embodiment is as follows: Start the drone body 1 and water pump 17. Water pump 17 draws medicine from water tank 7 through the first water pipe. During the drawing process, the medicine flows through the filter plate 10 inside water tank 7 and filters impurities through the central filter screen 11 to prevent impurities from clogging the nozzles 19. The filtered medicine enters the diversion pipe 18 through the second water pipe at the output end of water pump 17, and is finally evenly sprayed onto the target area through several nozzles 19 on one side of the diversion pipe 18. When the filter plate 10 needs to be cleaned after a period of use, the handle 14 on the outside of water tank 7 can be pulled. The handle 14 drives the locking rod 15 to move outward, and the tension spring 13 is stretched. When the locking rod 15 is completely disengaged from the limiting hole 16 on the slide bar 9, the filter plate 10 slides outward along the positioning strip 8 until the filter plate 10 and the central filter screen 11 are completely pulled out. The filter screen 11 is then cleaned to remove surface impurities. After cleaning, align the slide bar 9 with the groove of the positioning bar 8, and slide the filter plate 10 inward along the positioning bar 8 until the filter plate 10 is fully reset. Release the handle 14, the tension spring 13 rebounds, and the locking rod 15 passes through the positioning hole 12 and is locked into the limiting hole 16 of the slide bar 9 to fix the filter plate 10. Replace the box cover 22 and tighten the bolts to fix it. In this device, the filter screen 11 can filter the medicine in the water tank 7, remove solid particles and impurities from the medicine, avoid impurities clogging the nozzle 19, ensure the unobstructed flow of the nozzle 19, and ensure that the medicine passes smoothly through the nozzle 19 to achieve uniform spraying. The filter plate 10 is slidably connected to the positioning bar 8 on the inner wall of the water tank 7 through the slide bar 9, and is fixed by the cooperation of the locking rod 15 and the limiting hole 16. When the filter screen 11 is blocked by impurities and affects the feeding, the filter plate 10 can be easily pulled out for cleaning to restore the filtration effect and ensure the stability of subsequent feeding.

[0046] For a specific embodiment two, please refer to Figure 1-4 Based on the first specific embodiment, positioning plates 21 are fixed on both sides of the water storage tank 7, and the tank cover 22 is fixed to the positioning plates 21 by bolts.

[0047] Specifically, the mounting plate 3 has a fixing hole 23 at one end, and a fixing strip 24 is movably connected inside the fixing hole 23; a connecting plate 25 is fixed to one side of the fixing strip 24.

[0049] The operation process of this embodiment is as follows: The water tank 7 is fixed inside the fixed housing 6, ensuring a firm connection between the fixed housing 6 and the mounting strip 5. The mounting strip 5 is slid along the mounting groove 4 on the surface of the mounting plate 3 until it is fully embedded in the mounting groove 4. At this point, the water tank 7 is initially positioned. Then, one end of the fixing strip 24 is inserted into the fixing hole 23 of the mounting plate 3, so that the connecting plate 25 fits against the side of the mounting plate 3, and the fixing plate 26 is aligned with the bottom of the mounting plate 3. The threaded rod 28 is screwed into the threaded hole 27 at the bottom of the fixing plate 26 and the mounting plate 3 until tightened. Through the cooperation of the fixing strip 24 and the threaded rod 28, the mounting strip 5 is fixed in the mounting groove 4, completing the installation and fixing of the water tank 7. When it is necessary to add... When adding the medicine, locate the positioning plates 21 on both sides of the water tank 7, unscrew the bolts fixing the tank cover 22 on the positioning plates 21, remove the tank cover 22, and pour the medicine to be sprayed into the water tank 7.
