Description

Technical Field

[0001] The present invention relates to the field of agricultural planting technology, and in particular to an unmanned aerial vehicle (UAV) spraying device for agricultural planting. Background Art

[0002] In agricultural production, pest control has always been a critical component in ensuring crop yield and quality. In recent years, the rapid development of drone technology has brought new solutions to agricultural spraying operations. Drones offer advantages such as high maneuverability, flexibility, and unrestricted terrain. They can quickly and efficiently traverse farmland, enabling large-scale spraying operations. Equipped with advanced navigation systems and intelligent control systems, drones can autonomously fly and precisely spray pesticides according to pre-set routes and parameters, effectively improving pesticide utilization and control effectiveness while reducing environmental pollution. Furthermore, the use of drones can significantly reduce farmers' labor intensity, increase the automation and modernization of agricultural production, and align with the trend of sustainable agricultural development.

[0003] After searching, the Chinese patent number CN111657250A discloses a drone spraying device for agricultural planting, comprising a drone body, a symmetrically arranged rotor fixedly mounted on the top of the drone body, legs fixedly mounted on both sides of the bottom of the drone body, a chassis disposed between the two legs, symmetrically arranged support rods fixedly mounted on the top of the chassis, a cross plate fixedly mounted on the top of the support rod, and stabilizing sleeves fixedly mounted on both sides of the top of the cross plate. The present invention drives the pipe to rotate through a drive assembly, causing the spray head to perform a circular motion along the inner wall of the circular groove, which is conducive to expanding the spraying range of the device, reducing the spraying time, and thus improving the spraying efficiency. There is no need to add additional planning and navigation routes, reducing the burden on the drone's endurance and flight, and has broad market prospects and is conducive to the promotion of agricultural planting.

[0004] During the use of the above-mentioned device, when spraying pesticides, the liquid sprayed inside is inconvenient to stir, and stratification and precipitation are likely to occur, resulting in a deterioration in the spraying effect. Therefore, a drone spraying device for agricultural planting is proposed. Summary of the Invention

[0005] In response to the problems in the related technology, the present invention proposes a drone spraying device for agricultural planting to overcome the above-mentioned technical problems existing in the existing related technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] The cam is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate, and the toothed plate is provided with a toothed plate.

[0008] The above technical solution further includes:

[0009] The bottom of the frame is fixedly connected to a support leg, a pull rod is provided on the side of the support leg, one end of the pull rod is connected to a sprayer, and the side of the sprayer is fixedly connected to the support leg.

[0010] The clamping mechanism includes a second threaded rod arranged on the side of the support leg, a first clamping frame is arranged outside the second threaded rod, a second clamping frame is arranged on the side of the second threaded rod away from the first clamping frame, and the second clamping frame is threadedly connected to the first clamping frame.

[0011] A base is rotatably connected to the lower portion of the first threaded rod, the base is fixed to the side of the support leg, the support leg is slidably connected to the first clamping frame and the second clamping frame, and the mixing box is slidably connected to the first clamping frame and the second clamping frame.

[0012] A control box is arranged above the frame, and a plurality of groups of wings for adjusting the height thereof are arranged above the frame.

[0013] An adjustment knob is installed on the side of the connecting rod to control the length of the connecting brush exposed outside the connecting rod. This knob is installed on the side of the connecting rod and is used to control the length of the connecting brush exposed outside the connecting rod, thereby adjusting the stirring range and position of the connecting brush within the mixing box. By adjusting the adjustment knob, the connecting brush can be brought closer to the inner wall or bottom of the mixing box to accommodate mixing boxes of different heights and volumes, as well as pesticide solutions of different concentrations and viscosities. This ensures sufficient stirring of the pesticide solution within the mixing box, improving the stirring effect and the uniformity of the pesticide solution, thereby ensuring spray quality.

[0014] The first rotatable block is connected to a transmission belt, which is in turn connected to the second rotatable block. The transmission belt connects the first and second rotatable blocks and effectively transmits the rotational energy of the first rotatable block to the second rotatable block, enabling the second rotatable block to rotate in a predetermined manner, thereby driving the threaded rod to achieve the mixing function of the mixing box moving up and down. The transmission belt has a certain degree of elasticity and buffering capacity, which can reduce shock and vibration during power transmission to a certain extent, protect related components, and also facilitate installation and maintenance, ensuring the stability and reliability of power transmission.

[0015] The side of the connecting block is fixedly connected with a stabilizing frame, and the interior of the connecting block is provided with a cavity for the rolling ball.

[0016] The legs are equipped with multiple groups of sprayers for applying pesticide liquid. These sprayers, with small holes for spraying the liquid, are the actuators for pesticide spraying. These holes disperse the pesticide solution in the tank into fine droplets, which are evenly sprayed onto crops. By controlling the opening and closing of the sprayers, as well as the size and spraying range of the droplets, precise pesticide application can be achieved based on the crop type, growth stage, and pest and disease status, improving pesticide utilization efficiency, reducing waste and environmental pollution, and ensuring effective pest and disease control.

[0017] The surface of the second threaded rod is provided with threads for the first clamping frame and the second clamping frame to be close to each other.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, the mixing box and its internal linkage stirring device, such as the first rotating block driving the second rotating block to move the mixing box up and down, simultaneously drive the connecting column, second annular sleeve, support rod, first annular sleeve, connecting rod, and connecting brush to perform circular motion along the inner wall of the mixing box, achieving all-round and efficient stirring of the pesticide. This effectively avoids the problem of stratification and sedimentation of the liquid pesticide, ensures that the composition of the liquid pesticide sprayed each time is uniform, and enables the pesticide to be evenly coated on the surface of the crop, greatly improving the pest control effect, reducing the recurrence of pests and diseases caused by uneven spraying, and ensuring the healthy growth of crops and stable yields.

[0020] 2. In the present invention, since the device can always keep the pesticide in a uniformly mixed state, during the spraying process, there will be no waste of pesticide due to some precipitated components not being sprayed out, which ensures the full utilization of the pesticide and reduces agricultural production costs.

The second annular sleeve 25 is provided on the side of the second annular sleeve 25, and the support rod 22 is fixedly connected to the other end of the support rod 22. The first annular sleeve 23 is fixedly connected to the connecting rod 16. One end of the connecting rod 16 is provided with an external gear 21. The outside of the connecting rod 16 is provided with a rotating ball 15, and the rotating ball 15 is rotatably connected to the connecting block 14. A connecting brush 18 is provided on the side of the connecting rod 16, and a clamping mechanism for fixing the mixing box 26 is provided on the side of the side frame 12. The clamping mechanism is used to clamp mixing boxes 26 of different volumes.

[0031] In one embodiment, for the above-mentioned frame 1, a support leg 4 is fixedly connected to the bottom of the frame 1, a pull rod 5 is provided on the side of the support leg 4, one end of the pull rod 5 is connected to a sprayer 6, and the side of the sprayer 6 is fixedly connected to the support leg 4.

[0032] In this embodiment, the main support structure of the entire drone spraying device carries other components, provides a stable physical framework for the device, ensures the relative position of each component is stable during flight and operation, and enables the entire device to work together to complete the pesticide spraying task.

[0033] In one embodiment, for the above-mentioned clamping mechanism, the clamping mechanism includes a second threaded rod 29 arranged on the side of the support leg 4, a first clamping frame 27 is arranged on the outside of the second threaded rod 29, and a second clamping frame 28 is arranged on the side of the second threaded rod 29 away from the first clamping frame 27, and the second clamping frame 28 is threadedly connected to the first clamping frame 27.

[0034] In one embodiment, for the above-mentioned first threaded rod 11, a base 30 is rotatably connected to the bottom of the first threaded rod 11, the base 30 is fixed to the side of the support leg 4, the support leg 4 is slidably connected to the first clamping frame 27 and the second clamping frame 28, and the mixing box 26 is slidably connected to the first clamping frame 27 and the second clamping frame 28.

[0035] In this embodiment, the first threaded rod 11 cooperates with the block 13, and through a threaded connection, it converts rotational motion into linear motion. When the threaded rod 11 rotates, the block 13 slides up and down along the side frame 12, thereby driving the mixing box 26 to move up and down, stirring the upper and lower layers of the pesticide solution in the mixing box, preventing stratification of the solution, ensuring uniformity of the pesticide, and improving the spraying efficiency and pest control effectiveness of the pesticide.

[0036] In one embodiment, for the control box 3 , a control box 3 is provided above the frame 1 , and a plurality of wings 2 for adjusting the height thereof are provided above the frame 1 .

[0037] In this embodiment, the control box 3 is responsible for receiving commands from the ground operator and converting them into control signals for the various components of the drone. It integrates multiple functional modules, including the flight control system and the spray control system. It can precisely control operations such as wing rotation, stirring in the mixing tank, opening and closing the sprayer, and spraying amount, ensuring the automation and precision of the entire spraying process.

[0038] In one embodiment, for the connecting rod 16 , an adjusting button 17 is provided on the side of the connecting rod 16 , and the adjusting button 17 is used to control the length of the connecting brush 18 exposed outside the connecting rod 16 .

[0039] In this embodiment, the connecting rod 16 connects the first annular sleeve 23, the rotating ball 15, the external transmission gear 21, and the connecting brush 18, serving to transmit power and support the connecting brush 18. When the first annular sleeve 23 rotates, the power is transmitted to the external transmission gear 21 through the connecting rod 16, causing it to mesh and rotate with the fixed gear plate 20, while simultaneously driving the connecting brush 18 to perform circular motion within the mixing box 26, thereby stirring the pesticide solution. In addition, the connecting rod 16 also provides an installation location for the adjustment knob 17, which can be used to control the position of the connecting brush 18 on the connecting rod 16, thereby adjusting the stirring effect of the connecting brush 18 at different positions within the mixing box 26 to meet the stirring requirements in different situations.

[0040] In one embodiment, for the first rotating block 8 , the first rotating block 8 is connected to a transmission belt 9 , and the transmission belt 9 is connected to a second rotating block 10 .

[0041] In this embodiment, the first rotating block 8 serves as one of the power input components for the stirring action of the stirring box. Its rotation can drive a series of transmission components such as the transmission belt 9 and the second rotating block 10 to move, thereby realizing the up and down movement of the stirring box 26 and the circular motion of the internal connecting brush 18, so that the pesticide solution in the stirring box is fully stirred, avoiding stratification and precipitation, ensuring the uniformity of the pesticide solution, thereby ensuring that the concentration and composition of the pesticide sprayed each time are consistent, and improving the spraying effect and prevention effect.

[0042] In one embodiment, for the above-mentioned connecting block 14 , a stabilizing frame 7 is fixedly connected to a side of the connecting block 14 , and a cavity for the rotating ball 15 to roll is provided inside the connecting block 14 .

[0043] In this embodiment, the connecting block 14 provides rotational support and guidance for the rotating ball 15. Its internal cavity allows the rotating ball 15 to roll freely within it, thereby enabling the connecting rod 16 to rotate flexibly within a certain range. This design enables the connecting brush 18 to perform a circular motion within the mixing chamber 26, thoroughly stirring the inner walls of the mixing chamber and the solution within, ensuring uniform mixing of the pesticide solution. Furthermore, the fixed connection between the connecting block 14 and the stabilizing frame 7 ensures the stability and reliability of the entire stirring transmission mechanism, ensuring continuous and stable stirring during drone flight and spraying operations.

[0044] In one embodiment, for the above-mentioned supporting legs 4, multiple groups of sprayers 6 for spraying liquid medicine are provided on the side of the supporting legs 4, and small holes for spraying liquid medicine are provided on the surface of the sprayers 6.

[0045] In this embodiment, the outriggers 4 provide support during landing and parking, protecting the frame and other components from ground impact and damage. Furthermore, the outriggers are also mounted with components related to spraying operations, such as the pull rod, sprayer, and clamping mechanism. These provide a stable mounting base for these components, ensuring their proper function during flight and operation. They also help maintain the center of gravity of the entire device, ensuring flight stability.

[0046] In one embodiment, for the second threaded rod 29 , a surface of the second threaded rod 29 is provided with threads for bringing the first clamping frame 27 and the second clamping frame 28 closer together.

[0047] In this embodiment, the second threaded rod 29 serves as the power component of the clamping mechanism. Its threads engage with the first and second clamping frames 27 and 28 to achieve relative movement between the two clamping frames, thereby clamping and securing the mixing box 26. The rotation of the threaded rod 29 can be achieved manually or electrically. The design of the threaded rod 29 requires guaranteed thread precision and strength to ensure that the clamping mechanism can reliably secure the mixing box 26 and withstand various forces during drone flight and operation, preventing the mixing box 26 from loosening or falling off, thereby ensuring safe and stable spraying operations.

[0048] The working principle of the drone spraying device for agricultural planting in the present invention is that the agricultural planting personnel rotate the threaded rod 29 by controlling the control box 3, so that the first clamping frame 27 and the second clamping frame 28 at both ends of the threaded rod 29 are close to each other, thereby fixing the mixing box 26 to be sprayed above the base 30, and then the threaded rod 29 continues to rotate. At this time, the first clamping frame 27 and the second clamping frame 28 will clamp the mixing box 26, thereby preventing the subsequent shaking of the mixing box 26 and the spillage of the liquid medicine.

[0049] Then the agricultural planting personnel use the ground control control box 3, and further control the multiple sets of wings 2 to rotate, so that the frame 1 is suspended at a suitable height for spraying the farmland. Then, the first rotating block 8 fixed inside the frame 1 rotates, and then the first rotating block 8 drives the second rotating block 10 to rotate through the transmission belt 9. The rotation of the second rotating block 10 will cause the mixing box 26 fixed on the side of the block 13 to move up and down along the threaded rod 11.

[0050] Then at the same time, the rotation of the first rotating block 8 will drive the connecting column 24 fixed under the disc 19 to rotate, and the rotation of the connecting column 24 will cause the second annular sleeve 25 sleeved on its surface to rotate, and the rotation of the second annular sleeve 25 will drive the support rod 22 to rotate, and the first annular sleeve 23 fixed on one side of the support rod 22 will drive its connecting rod 16 to rotate, and the external transmission gear 21 fixed on one side of the connecting rod 16 is engaged with the fixed gear disk 20. The outer sleeve of the connecting rod 16 is provided with a rotating ball 15, and the rotating ball 15 will slide on the connecting block 14 fixed on the side of the stabilizing frame 7, so that the connecting brush 18 fixed on the side of the connecting rod 16 performs a circular motion along the inner wall of the mixing box 26. While rotating, the mixing box 26 moves up and down, thereby evenly stirring the upper and lower layers of the mixing box 26 to prevent stratification and make it evenly stirred. Finally, it is sprayed out by the sprayer 6, thereby realizing the spraying of the drone.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
