Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to a pesticide spraying unmanned aerial vehicle with high spraying efficiency. Background Art

[0002] With the advancement of smart farmland management, agricultural drones are gradually becoming an important tool in agricultural production. The application prospects of agricultural drones are broader, which will help promote the digital transformation and sustainable development of agricultural production. At the same time, the agricultural drone market is also facing challenges in the training of technical talents. In the future, more professional talents will be needed to support the rapid development of this field. Pesticide spraying drones are a type of agricultural drones and are also the most commonly used agricultural drones.

[0003] At present, the pesticide spraying drones on the market are usually composed of drones, spraying devices and other parts. Pesticide spraying drones usually fly between fields, so the flight conditions are relatively complicated and prone to explosions. When the drone explodes and falls, the propeller will be damaged, and the rotation of the propeller when the staff is loading pesticides will also have a safety impact on the staff, so the propeller needs to be protected by a protective cover. First, the propeller can be protected when the drone explodes, and second, the staff can be protected. When the pesticide spraying drone is in use, the staff can load the pesticide in the medicine box of the spraying device, and then the drone will work to take off the spraying device. The spraying device takes off and sprays the pesticide on the crops through the nozzle. After the pesticide spraying is completed, the drone will take the spraying device back to the original place for the staff to load the pesticide. However, this method is very time-consuming. The drone will be in a stopped state when the staff is loading the pesticide, which greatly reduces the efficiency of pesticide spraying. Summary of the invention

[0015] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects: 1. Two groups of spraying components are set up. When the drone takes off, one group of spraying components will work first. When the first group of spraying components finishes spraying pesticides, the drone can fly back to the original place for landing. When the drone lands, the connecting components can be separated by the descending extrusion force, so as to disassemble the first group of spraying components that have sprayed pesticides. Then the drone flies to the top of the second group of spraying components and assembles the connecting components by descending. After the connecting components are assembled, the drone can lead the second group of spraying components to continue spraying pesticides. When the second group of spraying components is spraying pesticides, the staff can take advantage of the gap to load pesticides into the first group of spraying components, thereby eliminating the process of waiting for pesticide loading, greatly improving the efficiency of pesticide spraying; 2. The medicine box is equipped with a battery that can provide flying power for the drone. When the drone replaces the spraying component, the battery can be connected to the drone through the connection of the connector and the plug, so that the drone can use the power of the battery on the spraying component when flying to spray pesticides. When the spraying component is replaced, the drone's own power supply will be used, which can greatly increase the flight time of the drone; 3. A water pump is provided to generate strong suction when working. The suction of the water pump can transport the pesticide to the inside of the delivery port through the medicine inlet hole. The pesticide passes through the turbine when entering the inside of the delivery port. When the pesticide passes through the turbine, pressure is generated to make it rotate counterclockwise. When the turbine rotates counterclockwise, it can drive the rotating shaft, the rotating column and the anti-sedimentation rod to rotate. When the anti-sedimentation rod rotates, it stirs the pesticide at the lower part of the inner side of the medicine box, so that the pesticide can avoid precipitation when spraying; 4. When the pesticide enters the inside of the conveying port, it will pass through the filter cover and enter the inside of the conveying pipe. When the pesticide passes through the filter cover, the filter cover will filter the larger particles inside the pesticide. At the same time, when the shaft rotates, it will drive the gear 1 at the bottom to rotate. When the gear 1 rotates, it can drive the gear 2 to mesh and rotate. When the gear 2 meshes and rotates, it can drive the filter cover to rotate. When the filter cover rotates, the cleaning brush on the inner wall of the conveying port will clean the impurities on the filter cover, so that the filter cover can be cleaned in real time. 5. When the connector is connected to the plug, the motor can be started through the power cord to work. When the motor is working, the cooperation of the bevel gear 2 and the bevel gear 1 drives the rotating column 2 and the isolation plate to rotate clockwise. When the isolation plate rotates clockwise, the cooperation of the card block and the card slot can drive the rotating column 1 and the anti-sedimentation rod to rotate. The rotation of the isolation plate and the anti-sedimentation rod can mix and stir the pesticide inside the medicine box. When the pesticide is sprayed, the motor stops working. The isolation plate can isolate the pesticide inside the medicine box through the circular array distribution, thereby reducing the shaking of the pesticide inside the medicine box when the drone stops and flies.

[0024] It should be understood that when the drone 1 is raised or lowered, the spraying component 3 can be replaced by the connecting component 2, and the two sets of spraying components 3 can be used in turn, thereby reducing the waiting time for filling pesticides, and the charging component 4 can be used to provide power to the drone 1 in turn, thereby increasing the flight time of the drone 1.

[0025] like Figure 1-Figure 3 As shown, the connection assembly includes a docking seat fixedly installed at the bottom of the drone, and a connecting column fixedly installed at the top of the spraying assembly. The docking seat and the connecting column can be engaged with each other, and after the docking seat and the connecting column are engaged, the assembly of the drone and the spraying assembly is fixed. The bottom of the drone 1 is fixedly connected with a mounting column 21, and the bottom end of the mounting column 21 is fixedly connected with a docking seat 22. The outer peripheral surface of the docking seat 22 is provided with four groups of adjustment grooves 23 in a circular array. The upper part of the four groups of adjustment grooves 23 is provided with positioning grooves 24. When the slot 26 slides downward, the docking seat 22 will drive the adjustment groove 23 and the adjustment rod 215 to slide. When the adjustment groove 23 and the adjustment rod 215 slide, the adjustment rod 215 will squeeze the inclined surface of the adjustment groove 23. When the adjustment groove 23 is squeezed, the drone 1 will rotate. When the drone 1 rotates to the specified position, the adjustment rod 215 will be inserted into the positioning groove 24. When the adjustment rod 215 is inserted into the positioning groove 24, the spraying assembly 3 can be adjusted. For positioning, an oblique guide groove 25 is provided at the bottom of the docking seat 22, a slot 26 is provided at the upper center of the oblique guide groove 25, and four groups of extrusion grooves 27 are provided on the inner wall of the slot 26 in a circular array. Springs 28 are fixedly connected to the inside of the four groups of extrusion grooves 27, and the ends of the springs 28 are fixedly connected to the limiting blocks 29. A mounting frame 210 is fixedly connected to the spraying assembly 3, and a connecting column 211 is fixedly connected to the top of the mounting frame 210. The outer peripheral surface of the connecting column 211 A groove 212 is provided, a disassembly ring 213 is sleeved on the surface of the groove 212, an insert block 214 is fixedly connected to the top of the groove 212, the maximum diameter of the insert block 214, the connecting column 211 and the disassembly ring 213 is the same as the diameter of the slot 26, the insert block 214 and the disassembly ring 213 are both funnel-shaped, and an adjusting rod 215 is fixedly connected to the top of the mounting frame 210 near the connecting column 211, and four groups of adjusting rods 215 are provided, and the four groups of adjusting rods 215 are slidably connected to the positioning groove 24.

[0026] It is worth noting that when the drone 1 takes off, it can drive the mounting column 21 and the docking seat 22 to move. When the docking seat 22 moves, it can drive the oblique guide groove 25 and the slot 26 to move. When the oblique guide groove 25 moves to the top of the plug block 214, the drone 1 will descend. When the drone 1 descends, it can drive the oblique guide groove 25 to squeeze the plug block 214. Since the oblique guide groove 25 is funnel-shaped, the oblique guide groove 25 will gradually correct the position of the drone 1 when it descends. When the position of the drone 1 is corrected, the plug block 214 will gradually slide into the slot 26 located at the center of the oblique guide groove 25. At this time, the slot 26 will continue to move downward and slide with the plug block 214. When the slot 26 slides downward, it can drive the tilt of the limit block 29 The inclined surface is pressed against the surface of the insert block 214, and the limit block 29 is pressed to slide into the extrusion groove 27. When the limit block 29 slides, it will press the spring 28. When the limit block 29 completely slides into the extrusion groove 27, the slot 26 will continue to drive the limit block 29 to move downward. When the limit block 29 moves to the side of the groove 212, it can be reset by the elastic force of the spring 28 itself. When the limit block 29 is reset, it will be inserted into the groove 212. At this time, the drone 1 stops descending and will fly upward to lift the bottom of the insert block 214 through the limit block 29. When the insert block 214 is lifted, the spraying assembly 3 can be lifted through the mounting frame 210. When the spraying assembly 3 is lifted, the pesticide will be sprayed. When the pesticide spraying inside the spray assembly 3 is completed, the drone 1 flies back to its original position and descends. When the drone 1 descends, the spray assembly 3 will fall to the ground, and the drone 1 will continue to descend. When the drone 1 continues to descend, it can drive the docking seat 22, the slot 26 and the limit block 29 to move downward. When the limit block 29 moves downward, it can slide inside the groove 212. When the limit block 29 slides to the top of the disassembly ring 213, its inclined surface can squeeze the top of the disassembly ring 213. When the limit block 29 is squeezed, it will slide into the inside of the extrusion groove 27. When the limit block 29 is completely squeezed into the inside of the extrusion groove 27, the limit block 29 will continue to move downward along the surface of the disassembly ring 213. When the limit block 29 moves to the lower edge of the disassembly ring 213, the limit block 29 can be reset by the elastic force of the spring 28. When the limit block 29 is reset, it can squeeze the disassembly ring 213 and When the disassembly ring 213 moves upward, it will push the bottom of the disassembly ring 213 to move upward. When the disassembly ring 213 moves upward, it will slide inside the groove 212. When the disassembly ring 213 slides to the bottom of the plug-in block 214, it will stop moving. When the disassembly ring 213 stops moving, the limit block 29 will squeeze its inclined surface, and the limit block 29 will slide toward the inside of the extrusion groove 27. When the limit block 29 completely slides into the inside of the extrusion groove 27, the upward flight of the drone 1 will drive the limit block 29 to slide out of the surface of the disassembly ring 213 and the plug-in block 214. When the plug-in block 214 slides out of the slot 26, the adjusting rod 215 will also slide out of the positioning groove 24 and the adjusting groove 23. When the limit block 29 slides out of the surface of the plug-in block 214, the spray assembly 3 will also be disassembled. like Figure 1 and Figure 4-Figure 6As shown, the spray assembly 3 includes a fixing frame 31, the fixing frame 31 is fixedly connected to the top of the mounting frame 210, a medicine box 32 is arranged inside the fixing frame 31, a medicine inlet 33 is installed on the top of the medicine box 32, a cleaning port 34 is installed on the bottom of the medicine box 32, a delivery port 35 is installed on the inner side of the medicine box 32 near the cleaning port 34, a baffle plate 36 is fixedly connected to the side of the fixing frame 31, and a delivery pipe 37 is fixedly installed on the surface of the baffle plate 36, the medicine box 32 and the delivery port 35 through an assembly hole, a water pump 38 is installed on the delivery pipe 37, and the delivery pipe 37 is near the baffle plate 36. A nozzle 39 is installed at one end, a turbine 310 is rotatably installed on the inner side of the delivery port 35 through a bearing, a rotating shaft 311 is installed through the turbine 310 and the delivery port 35 through an assembly hole, a rotating column 312 is fixedly connected to the top of the rotating shaft 311, a plurality of groups of anti-sedimentation rods 314 are fixedly connected to the outer peripheral surface of the rotating column 312 in a circular array, a rotating groove 313 is provided at the top of the rotating column 312, a clamping groove 321 is provided on the inner wall of the rotating groove 313, a rotating block 322 is rotatably connected to the inner side of the rotating groove 313, and an extrusion rod 322 is provided on the outer peripheral surface of the rotating block 322. The second groove 323, the inner side of the extrusion groove 323 is fixedly connected with a spring 324, the end of the spring 324 near the slot 321 is fixedly connected with a card block 325, the top of the rotating block 322 is fixedly connected with a rotating column 2 326, the top of the rotating column 2 326 passes through the top of the medicine box 32, and the outer peripheral surface of the rotating column 2 326 is fixedly connected with a plurality of isolation plates 327 in a circular array. The top of the rotating column 2 326 is installed with a bevel gear 1 328, and the side of the bevel gear 1 328 is meshed with a bevel gear 2 329, and the inner side of the bevel gear 2 329 is through an assembly hole A motor 330 is installed through it and is installed on the top of the medicine box 32. A medicine inlet hole 315 is opened through the surface of the delivery port 35 near the turbine 310. A gear 1 316 is fixedly connected to the bottom end of the rotating shaft 311. A matching gear 2 318 is connected to the side of the gear 1 316. A filter cover 317 is fixedly installed on the inner side of the gear 2 318 through an assembly hole. The filter cover 317 is rotatably connected to the end of the delivery port 35. A cleaning brush 319 is fixedly connected to the inner side of the delivery port 35 near the filter cover 317. A supporting foot 320 is installed at the bottom of the fixed frame 31.

[0027] It can be understood that when the drone 1 takes off, the mounting frame 210 can drive the fixing frame 31 to rise, and when the fixing frame 31 rises, it will drive the medicine box 32 to move. When the medicine box 32 moves to the upper part of the crop, the water pump 38 can work. When the water pump 38 works, it will generate suction to transport the pesticide inside the medicine box 32 to the delivery port 35 through the medicine inlet hole 315. When the pesticide enters the delivery port 35, it will flow downward, and the pesticide will pass through the turbine 310 when moving downward. When the pesticide passes through the turbine 310, it will generate an extrusion force to rotate. When the pesticide flows to the bottom of the delivery port 35, it will pass through the filter cover 317 and enter the inside of the delivery pipe 37. When the pesticide passes through the filter cover 317, the filter cover 317 will filter the impurities inside the pesticide. After entering the delivery pipe 37, the pesticide will be transported to the inside of the nozzle 39 through the water pump 38, and the nozzle 39 will spray the pesticide on the surface of the crop. When the turbine 310 rotates, it will drive the rotating shaft 311 to rotate. When the rotating shaft 311 rotates, it will drive the rotating column 1 312 to rotate. When the rotating column 1 312 rotates, it can drive the anti-sedimentation rod 314 to rotate. When the rotating column 1 312 rotates, it can rotate counterclockwise with the card slot 321 through the rotating groove 313. When the card slot 321 rotates counterclockwise, it can squeeze the inclined surface of the card block 325 through the inclined surface. When the card block 325 is squeezed, it can slide inside the extrusion groove 2 323. When the card block 325 slides, it can squeeze the spring 324. When the card block 325 is completely squeezed into the extrusion groove 2 323, the rotating groove 313 will continue to squeeze with the card block 325. The rotating block 322 rotates, and then the rotating column 1 312 can avoid driving the rotating column 2 326 and the isolation plate 327 to rotate when rotating. The anti-sedimentation rod 314 can stir the internal pesticide and water when rotating. The rotating shaft 311 will drive the gear 1 316 to rotate while rotating. When the gear 1 316 rotates, it will drive the gear 2 318 to mesh and rotate. When the gear 2 318 meshes and rotates, it can drive the filter cover 317 to rotate. When the filter cover 317 rotates, it will rub against the cleaning brush 319 on the inner wall of the conveying port 35. When the filter cover 317 rubs against the cleaning brush 319, the cleaning brush 319 will clean the impurities of the filter cover 317. When the connector 45 is connected to the plug 47, the motor 330 can be started through the power cord 44 to work. When the motor 330 is working, it can drive the bevel gear 2 329 to rotate. When the bevel gear 2 329 rotates, it can drive the bevel gear 1 328 to rotate. When the bevel gear 1 328 rotates, it can drive the rotating column 2 326 to rotate. When the rotating column 2 326 rotates, it can rotate clockwise at the top of the medicine box 32. When the rotating column 2 326 rotates clockwise, it can drive the isolation plate 327 to rotate. When the isolation plate 327 rotates clockwise, the cooperation between the card block 325 and the card slot 321 can drive the rotating column 312 and the anti-sedimentation rod 314 to rotate. The rotation of the isolation plate 327 and the anti-sedimentation rod 314 can mix and stir the pesticide inside the medicine box 32. When the pesticide is sprayed, the motor 330 stops working. The isolation plate 327 can isolate the pesticide inside the medicine box 32 through the annular array distribution, thereby reducing the shaking of the pesticide inside the medicine box 32 when the drone 1 stops and flies.

[0028] like Figure 1-Figure 4 As shown, the charging assembly 4 includes: a battery box 41, the battery box 41 is fixedly installed on the top of the medicine box 32, and the battery 42 is movably installed inside the battery box 41. A connecting groove 43 is opened on the top of the plug block 214, and a power cord 44 is connected to the inner side of the connecting groove 43. The ends of the power cord 44 are respectively connected to the battery 42 and the motor 330. The other end of the power cord 44 is connected to a connector 45, and the connector 45 is movably connected to the inside of the connecting groove 43. The bottom of the connecting groove 43 is connected to the bottom end of the spring 46, and the top of the spring 46 is connected to the bottom of the connector 45. The top of the connector 45 is connected to a plug 47 by means of plugging, and the top of the plug 47 is installed and connected to the top of the slot 26. When the spray assembly 3 is disassembled, the slot 26 will drive the plug 47 to move. When the plug 47 moves, it can squeeze the connector 45. When the connector 45 is squeezed, it can slide inside the connecting groove 43. When the connector 45 slides, it can squeeze the spring 2 46. When the spray assembly 3 is disassembled, the slot 26 will pull the slot 26 out of the connector 45. At this time, the connector 45 can be reset by the spring 2 46.

[0029] It can be understood that when the slot 26 is docked with the plug block 214, the slot 26 will drive the plug 47 to connect with the connector 45. After the plug 47 is connected to the connector 45, the drone 1 can be connected to the battery 42 through the power cord 44. At this time, the battery 42 on the spray component 3 can power the drone 1, so that the drone 1 can be powered by the battery 42 during the period when the spray component 3 is driven to spray pesticides, and the battery inside the drone 1 will stop working. When the pesticide spraying is completed, another set of spray components 3 can be replaced by disassembling the connecting component 2 to work. The drone 1 can use its own battery for power supply during the process of replacing the spray component 3.

[0030] Working principle: When using the pesticide spraying drone with high spraying efficiency, first fill the pesticide inside the medicine box 32. After the pesticide is filled, operate the drone 1 to take off. After the drone 1 takes off, it can drive the slot 26 to be sleeved on the side of the connecting column 211, the groove 212, the disassembly ring 213 and the plug block 214. When the slot 26 is sleeved, the limit block 29 can be inserted into the groove 212 through the elastic force of the spring 28 to limit the plug block 214. At this time, the drone 1 takes off upward. When the drone 1 takes off upward, The connection component 2 drives the spray component 3 to move. When the spray component 3 moves to the top of the crop, the water pump 38 works to transport the pesticide in the medicine box 32 to the inside of the nozzle 39 through the delivery pipe 37. The nozzle 39 can spray the pesticide on the surface of the crop. Before entering the inside of the delivery pipe 37, the pesticide will enter the inside of the delivery port 35 through the medicine inlet hole 315. When the pesticide enters the inside of the delivery port 35, the turbine 310 and the rotating shaft 311 can be driven to rotate by the flow pressure. When the rotating shaft 311 rotates, it can drive the rotating column 310 to rotate. 12. The connecting rod 313 and the anti-precipitation rod 314 rotate. When the anti-precipitation rod 314 rotates, the pesticide inside the medicine box 32 can be mixed and stirred. While the rotating shaft 311 rotates, the gear 316 can drive the gear 2 318 and the filter cover 317 to rotate. When the filter cover 317 rotates, the cleaning brush 319 can clean the impurities on its surface. After the pesticide spraying is completed, the drone 1 flies back to the original place and can make the limit block 29 detach from the surface of the disassembly ring 213 and the plug block 214 by descending and rising. After the limit block 29 is detached, the connecting component 2 can be separated. At this time, the drone 1 can be assembled with another group of spraying components 3 in the same way. After the other group of spraying components 3 are assembled, the pesticide can be continued to be sprayed. After the drone 1 is assembled with the spraying component 3, the battery 42 on the medicine box 32 can power the drone 1. When the drone 1 is separated from the spraying component 3, it can use its own battery to power it, thereby increasing the endurance of the drone 1.
