Description

Technical Field

[0001] This invention relates to the field of agricultural fertilization machinery technology, specifically to an agricultural planting monitoring drone that integrates water and fertilizer application. Background Technology

[0002] Drone fertilization is a modern agricultural technology that uses agricultural plant protection drones as carriers to achieve foliar fertilization or shallow root fertilization of crops by precisely controlling flight parameters and fertilizer spraying volume. Its core advantages are adaptability to complex terrain, improved fertilization efficiency, and reduced manual labor intensity.

[0003] In existing technologies, when fertilizing with integrated water and fertilizer machines mounted on drones, the method of direct downward spraying of water and fertilizer is usually adopted. This method results in uneven distribution of water and fertilizer, and considering the distance between the drone and the crops, it is easy to cause water and fertilizer evaporation. It is not suitable for all crops. Depending on the planting arrangement of crops and the strength of their external tissues, adaptive fertilization operations are required to improve the fertilization effect and harvest benefits. To address these shortcomings, we propose an integrated water and fertilizer machine for agricultural planting monitoring drones. Summary of the Invention

[0012] Preferably, the top of the transmission block is provided with a sliding arm, the middle of the sliding arm is provided with a hollow groove, the sliding arm is slidably connected to the base, and push shafts are fixedly connected to both sides. A swing arm is provided on the side of the push shaft, the middle of the swing arm is fixedly connected to the sweeping plate, and a torsion spring is provided at the connection between the swing arm and the sweeping plate. One end of the torsion spring abuts against the receiving tube.

[0013] Preferably, the bottom of the extension tube is fixedly connected to a turntable through the suspension plate, and a transmission block two is fixedly connected to the bottom of the turntable at the off-center position. A cross transmission arm is provided on the outer surface of the transmission block two. The cross transmission arm is slidably connected to the bottom of the suspension plate, and side plates are fixedly installed on both sides of the cross transmission arm.

[0014] Preferably, a receiving liquid tank is fixedly installed at the bottom of the suspension plate, the receiving liquid tank is connected to the bottom of the three-way pipe, the output end of the receiving liquid tank is connected to an output valve, and an output pipe is connected to the output valve.

[0015] Preferably, the bottom of the suspension plate is fixedly installed with connecting frames on both sides of the receiving liquid tank.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In this invention, the nozzle and spray pipe for fertilization are placed on the suspension plate that is movably connected to the base. When the drone carries the water and fertilizer machine to the fertilization area, the motor starts and the two winding rollers release the steel wire rope, and the suspension plate moves downward, pulling closer to the fertilized crop. During the fertilization process, the fertilization distance can be shortened, reducing the amount of water and fertilizer evaporation caused by the downward fall of water and fertilizer.

[0020] In this invention, the arrangement and growth path of the fertilized crops are different. For crops that grow upward and usually have spacing, the cylinder outputs outward to turn the receiving tube into a vertical state and moves between the two rows of crops to fertilize. For crops that are arranged horizontally and have a low horizontal height, the receiving tube is placed horizontally to fertilize, so as to adapt to different types of crops for fertilization and improve the crop's efficiency in receiving water and fertilizer.

[0021] In this invention, for crops with fragile tissue structures, when the nozzle outputs water and fertilizer, it pushes the swing arms on both sides through the push shaft, so that the sweeping plate receives the output water and fertilizer and delays the time it takes to reach the crop surface. Furthermore, the fertilizer application path is changed from direct spraying to sweeping, which helps to protect the crop tissue structure and avoid damage to the crop. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 8 The present invention provides a technical solution: including a body 1, a base 2 is provided below the body 1, a fertilizer tank 3 is detachably installed in the middle of the base 2, a mounting frame 4 is fixedly connected to the top of the base 2, the mounting frame 4 is detachably connected to the body 1, a scissor lift 5 is hinged to both sides of the bottom of the mounting frame 4, and a suspension plate 6 is hinged to the bottom of the scissor lift 5.

[0033] A connecting shaft 7 is rotatably mounted on the mounting frame 4. A motor 8 is driven on one side of the connecting shaft 7. The motor 8 drives the connecting shaft 7 to rotate. A winding roller 9 is fixedly connected to both ends of the connecting shaft 7. A steel wire rope 10 is wound on the winding roller 9. One end of the steel wire rope 10 is fixedly connected to the suspension plate 6.

[0034] The bottom of the fertilizer tank 3 is connected to a hose 11. The end of the hose 11 away from the fertilizer tank 3 is connected to a main valve 12. The output end of the main valve 12 is connected to a three-way pipe 13. The top end of the three-way pipe 13 is connected to a control pipe 14. The two sides of the control pipe 14 are sealed and connected to a receiving pipe 15. The receiving pipe 15 is rotatably connected to the control pipe 14.

[0035] The receiving tube 15 is linearly arrayed with several nozzles 16. The two ends of the receiving tube 15 are hinged with sweeping plates 17. The two sides of the receiving tube 15 that are close to each other are fixedly connected with a synchronizing rod 18. The surface of the synchronizing rod 18 is opened through a through hole 19. A cylinder 20 is fixedly installed on one side of the suspension plate 6. The output end of the cylinder 20 is drivenly connected to a mounting ring 21. The end of the mounting ring 21 is movably sleeved on the synchronizing rod 18 through the through hole 19.

[0036] Slip rings 22 are fixedly connected to both sides of the suspension plate 6, and the receiving tube 15 is slidably mounted on the slip rings 22;

[0037] An electromagnet 23 is fixedly installed on one side of the top of the receiving tube 15, and a magnetic suction component 24 is movably arranged on the side of the electromagnet 23. The magnetic suction component 24 is located at the middle position of both sides of the suspension plate 6.

[0038] A toothed sleeve 25 is slidably connected to the base 2. The toothed sleeve 25 passes through the base 2. An extension tube 26 is slidably connected inside the toothed sleeve 25. The extension tube 26 is connected to the toothed sleeve 25 through a groove on its surface. The bottom of the extension tube 26 is rotatably mounted on the surface of the suspension plate 6.

[0039] In this embodiment, the fertilizer tank 3 is mounted on the mounting frame 4 of the drone base 2. After the drone flies to the fertilization area and hovers, the motor 8 drives the connecting shaft 7 to rotate, which drives the winding roller 9 to release the wire rope 10. The suspension plate 6 is lowered along with the wire rope 10, which synchronously drives the scissor frame 5 to unfold downwards. After the wire rope 10 is fully released, the scissor frame 5 locks its length, so that the suspension plate 6 and the spraying components are suspended at the target height above or between the crops.

[0040] In this embodiment, the rigid support structure of the scissor lift 5 can effectively suppress the swaying of the suspension plate 6 caused by the flight of the drone or airflow disturbance. During the lowering process, the toothed sleeve 25 and the extension tube 26 are opened synchronously and maintain the transmission connection, providing a power transmission path for the subsequent adjustment of the spraying components.

[0041] A gear 27 is engaged on the side of the meshing sleeve 25. A motor 28 is installed on the top of the gear 27. The motor 28 drives the gear 27 to rotate. One end of the pulley assembly 29 is connected to the bottom of the gear 27. The pulley assembly 29 is rotatably mounted on the base 2. A transmission block 30 is fixedly connected to the end of the pulley assembly 29 away from the gear 27. The transmission block 30 is located at the off-axis center of one of the pulleys in the pulley assembly 29.

[0042] A sliding arm 31 is provided on the top of the transmission block 30. A hollow groove 32 is provided through the middle of the sliding arm 31. The sliding arm 31 is slidably connected to the base 2, and push shafts 33 are fixedly connected on both sides. A swing arm 34 is provided on the side of the push shaft 33. The middle of the swing arm 34 is fixedly connected to the sweeping plate 17. A torsion spring 35 is provided at the connection between the swing arm 34 and the sweeping plate 17. One end of the torsion spring 35 abuts against the receiving tube 15.

[0043] In this embodiment, the crop targeted is usually a fruit crop that grows upward. In the early stage of crop growth, the structural strength of the fruit is not high, and it is easily separated from the branches by the spraying of water and fertilizer.

[0044] In this embodiment, for crops with partitioned spaces, the control cylinder 20 outputs outward, driving the synchronization rod 18 to swing the two receiving tubes 15 to an upright state. The receiving tubes 15 can move down along the crop partitioned space to improve the water and fertilizer reception efficiency of the lower crops. For densely planted crops without partitioned spaces, the cylinder 20 retracts inward, and the receiving tubes 15 remain in a horizontal state to achieve large-area horizontal spraying coverage.

[0045] In this embodiment, the electromagnet 23 at the top of the receiving tube 15 is attracted to the magnetic attraction component 24 of the base 2 after being energized, which enhances the structural stability in the upright state.

[0046] In this embodiment, the water and fertilizer in the fertilizer tank 3 are transported to the main valve 12 via the hose 11, then diverted to the control pipe 14 via the three-way pipe 13, and then distributed to the receiving pipes 15 on both sides by the control pipe 14, and finally sprayed outward through the nozzle 16 at the end of the receiving pipe 15.

[0047] In this embodiment, the starting motor 28 drives the gear 27 to rotate, which in turn drives the transmission block 30 to rotate through the pulley group 29. The hollow groove 32 at the top of the transmission block 30 drives the sliding arm 31 to slide back and forth on the base 2. The push shafts 33 at both ends of the sliding arm 31 alternately push the swing arm 34, causing the sweeping plate 17 to swing back and forth around the receiving tube 15. The swinging sweeping plate 17 comes into contact with the water and fertilizer sprayed from the nozzle 16, changing the direct path of the water and fertilizer, and transforming the hard impact contact between the water and fertilizer and the crop into a soft contact, reducing the damage of the water and fertilizer impact force to the crop. After a single swing, the torsion spring 35 between the swing arm 34 and the sweeping plate 17 releases elastic potential energy, causing the sweeping plate 17 to automatically return to its position, and the flexible spraying is completed in a cycle.

[0048] The bottom of the extension tube 26 passes through the suspension plate 6 and is fixedly connected to the turntable 36. The bottom of the turntable 36 is fixedly connected to the off-center part of the axis. The outer surface of the transmission block 37 is provided with a cross transmission arm 38. The cross transmission arm 38 is slidably connected to the bottom of the suspension plate 6. Side plates 39 are fixedly installed on both sides of the cross transmission arm 38.

[0049] A receiving liquid tank 40 is fixedly installed at the bottom of the suspension plate 6. The receiving liquid tank 40 is connected to the bottom of the three-way pipe 13. The output end of the receiving liquid tank 40 is connected to an output valve 41, and an output pipe 42 is connected to the output valve 41.

[0050] The bottom of the suspension plate 6 is fixedly installed with connecting brackets 43 on both sides of the receiving liquid tank 40. The bottom of the connecting bracket 43 is inclined and fixedly connected with a stop plate 44. The inside of the connecting bracket 43 is rotatably connected with a movable bracket 45. The front side of the movable bracket 45 is connected with a spray pipe 46, and the side of the movable bracket 45 is connected to the other end of the output pipe 42.

[0051] The movable frame 45 is connected to an elastic telescopic rod 47 on one side relative to the spray pipe 46. An extension plate 48 is fixedly connected to the output section of the elastic telescopic rod 47. The extension plate 48 is L-shaped and the top of the extension plate 48 abuts against the side plate 39.

[0052] A counterweight frame 49 is fixedly installed on the side of the suspension plate 6 relative to the receiving liquid tank 40;

[0053] In this embodiment, for crop areas with long transverse fertilization paths, the toothed sleeve 25 rotates, causing the extension tube 26 to rotate synchronously. The turntable 36 at the bottom of the extension tube 26 drives the transmission block 37 to rotate. The transmission block 37 drives the cross transmission arm 38 to move. The side plate 39 on the cross transmission arm 38 first pushes the extension plate 48, causing the movable frame 45 to rotate around the connecting frame 43, which drives the spray pipe 46 from an inclined state to a horizontal state, extending the spraying distance. Then, the side plate 39 continues to push the extension plate 48, causing the elastic telescopic rod 47 to extend outward. The spray pipe 46 remains in a horizontal state, realizing spraying deep into the roots of the crop.

[0054] In this embodiment, the fertilization time when the spray pipe 46 is in the horizontal long-range spray state is longer than the time when it is in the inclined close-range spray state. The spray pipes 46 arranged symmetrically on both sides work alternately to complete the uniform fertilization of the crop roots in the whole area.

[0055] The method of use and advantages of this invention: This agricultural planting monitoring drone with integrated water and fertilizer system operates as follows:

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0057] S1: During fertilization, water and fertilizer are introduced into the fertilizer tank 3. The mounting bracket 4 on the top of the base 2 is connected to the bottom of the machine body 1. The machine body 1 drives the base 2 and fertilizer tank 3 to rise and fly to the fertilization area. After positioning, the motor 8 drives the connecting shaft 7 to rotate, causing the winding rollers 9 on both sides of the connecting shaft 7 to release the wound steel wire rope 10. During this process, the suspension plate 6 descends, and the scissor lift 5 extends downward. When the steel wire rope 10 is completely released, the scissor lift 5 stops extending, and the suspension plate 6 is suspended, bringing the output end of the water and fertilizer equipment close to the crop. The scissor lift 5 prevents the suspension plate 6 from being suspended. During flight, swaying occurs. During the deployment of the scissor lift 5, the toothed sleeve 25 and the extension tube 26 are synchronously opened, but the transmission state is maintained. At this time, depending on the fertilization situation, the cylinder 20 is controlled to output or remain retracted. When fertilizing crops with partitioned spaces, the cylinder 20 outputs outward, driving the synchronizing rod 18 to swing the two receiving tubes 15, making them stand upright. The two receiving tubes 15 move in the partitioned space between crops to carry out fertilization operations, improving the efficiency of the lower crops in receiving water and fertilizer. For crops without partitioned spaces, the two receiving tubes 15 are placed horizontally for fertilization.

[0058] S2: When the receiving pipe 15 is set in a vertical position, it has high efficiency in vertical fertilization of crops and a wide coverage area. The electromagnet 23 installed at the top of the receiving pipe 15 is energized when it approaches the magnetic attractor 24, so that the electromagnet 23 is attracted to the base 2. Water and fertilizer are input into the three-way pipe 13 through the hose 11 and the main valve 12. Water and fertilizer flow through one end of the three-way pipe 13 to the control pipe 14. The water and fertilizer in the control pipe 14 are respectively introduced into the receiving pipe 15 on both sides. After passing through the receiving pipe 15, they are sprayed outward through the nozzle 16. During the fertilization process, for crops with fragile structures and easy damage, the motor 28 is started, which drives the gear 27 to rotate. The bottom of the gear 27 drives the pulley group 29 to run. The pulley on the other side of the pulley group 29 rotates synchronously, driving the transmission block 30 at that location. The top of the rotating device drives the sliding arm 31 to slide back and forth on the base 2 via the hollow groove 32. The push shafts 33 at both ends of the sliding arm 31 push the two swing arms 34 respectively. The two swing arms 34 drive the sweeping plate 17 to swing around the receiving tube 15. During the process, the sweeping plate 17 comes into contact with the water and fertilizer sprayed from the nozzle 16. During the swing, the output path of the water and fertilizer is changed, so that the contact mode between the water and fertilizer and the crop is changed from hard contact to soft release. After the water and fertilizer pass through the sweeping plate 17, they come into contact with the surface of the crop, so that the impact force of the water and fertilizer on the crop is reduced, and the impact damage caused to the crop by fertilization is reduced. After each push shaft 33 pushes the swing arm 34 to make the sweeping plate 17 swing, it returns to its original position. The torsion spring 35 between the swing arm 34 and the sweeping plate 17 is released, so that the sweeping plate 17 returns to its original position.

[0059] S3: For root fertilization of crops, the bottom of the three-way pipe 13 inputs water and fertilizer into the receiving liquid tank 40, and then guides it into the spray pipe 46 through the output valve 41 and the output pipe 42. In the initial state, the bottom of the spray pipe 46 is in contact with the surface of the baffle plate 44, and the spray pipe 46 is in an inclined state to fertilize the roots of crops on both sides of the flight space. When the toothed sleeve 25 rotates, it drives the extension pipe 26 to rotate synchronously. The turntable 36 at the bottom of the extension pipe 26 drives the transmission block 37 to rotate. When the transmission block 37 rotates to the side close to the suspension plate 6, the transmission block 37 drives the cross transmission arm 38 to move in the same direction. During the process... The side plate 39 contacts the surface of the extension plate 48. Initially, the extension plate 48 drives the movable frame 45 to rotate around the connecting frame 43 as the center point, so that the spray pipe 46 changes from an inclined state to a horizontal state, spraying fertilizer into the internal space of the crop and extending the fertilization distance. Subsequently, the side plate 39 pushes the horizontal extension plate 48, so that the extension plate 48 drives the output end of the elastic telescopic rod 47 to extend outward. During the process, the spray pipe 46 remains horizontal. For the fertilization time of the crop roots, the spraying time to a distance is longer than the spraying time to a nearby area. The spray pipes 46 arranged symmetrically on both sides alternately fertilize the roots.
