Description

Technical Field

[0001] This invention relates to the field of agricultural drone technology, specifically to an agricultural plant protection drone suitable for multi-specification material containers. Background Technology

[0002] Agricultural plant protection drones are unmanned aerial vehicles used for the protection of agricultural and forestry plants. These drones possess efficient flight capabilities and precise positioning systems, enabling them to complete large-scale plant protection operations in a short time. Following pre-set flight paths, drones can evenly spray pesticides or fertilizers, ensuring that every inch of land receives proper treatment. Pesticide spraying is one of the most widespread applications of drones. Compared to traditional plant protection operations, drones offer advantages such as precision, high efficiency, environmental friendliness, intelligence, and ease of operation. They can spray pesticides at low altitudes, completing the work on one acre per minute, making their spraying efficiency 30 times that of traditional manual labor.

[0003] When existing agricultural plant protection drones simultaneously spray foliar fertilizer and growth regulators, the volume of the foliar fertilizer is greater than that of the growth regulator, resulting in an uneven weight distribution at both ends of the drone. This significant difference in the weight of the sprayed liquid at each end causes the drone to tilt or sway during flight, increasing flight instability and leading to uneven spraying. Consequently, the foliar fertilizer and growth regulator cannot be evenly sprayed onto the crop according to the predetermined ratio and amount, affecting the crop's absorption and growth. Uneven spraying results in an imbalance of nutrients absorbed by the crop, further impacting its normal growth and development. Summary of the Invention

[0010] Furthermore, the multi-specification fixing component includes a handle post and several retaining rings. The handle post is movably installed inside the material carrier frame, and retaining rings are evenly installed on the outer surface of the handle post.

[0018] Beneficial effects

[0019] The present invention has the following beneficial effects:

[0020] (1) This agricultural plant protection drone, applicable to multiple specifications of material containers, weighs the foliar fertilizer nutrient solution container and the growth regulator container respectively through two main weighing devices, and adds liquid to one of the counterweight tubes according to the weight difference between the two to ensure that the weight of the two ends of the drone device is consistent before spraying. The two counterweight tubes are connected by a connecting pipe to form a connecting device, realizing proportional weighting and further enhancing the accuracy of weighting. The agricultural plant protection drone device with consistent weight is more stable during flight, reducing flight deviation and safety hazards caused by uneven weight. The foliar fertilizer nutrient solution and growth regulator are sprayed simultaneously, improving spraying efficiency and ensuring that crops can receive both nutrients at the same time.

The hexagonal threaded nail moves the upper extrusion plate and sponge sleeve through the connecting block, thereby fixing different specifications of material containers. It can also fix the top and bottom of the four sides of the material containers, preventing the foliar fertilizer nutrient solution and growth regulator material containers from falling off due to shaking during transportation and spraying. It can achieve effective fixing within the limited internal space of the material frame and can adapt to a variety of different sizes and shapes of material containers.

[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] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0033] Please see Figures 1-7 This invention provides a technical solution: an agricultural plant protection drone suitable for multi-specification material containers, including an agricultural plant protection drone device 1. The agricultural plant protection drone device 1 has two material-carrying frames 3 installed inside. Each of the two material-carrying frames 3 has a material container cavity 2 inside. Each of the two material-carrying frames 3 has multi-specification fixing components installed inside. Each of the two multi-specification fixing components has four lower extrusion plates 16 installed on its outer surface. Each of the two material-carrying frames 3 has four medicine tank plus fixing components installed inside. Each of the eight medicine tank plus fixing components has an upper extrusion plate 29 installed on its outer surface. The outer surfaces of the eight upper extrusion plates 29 and the outer surfaces of the eight lower extrusion plates 16 are covered with sponge sleeves 17. Each of the two material-carrying frames 3 has a counterweight component installed inside.

[0034] The counterweight assembly includes support columns 4 and a main weighing device 5. Support columns 4 are installed inside the material loading frame 3, and the main weighing device 5 is installed on the top surface of each support column 4. Two counterweight platforms 6 are located inside the material loading frame 3, and auxiliary weighing devices 35 are installed inside each of the two counterweight platforms 6. Two counterweight tubes 30 are movably installed inside the material loading frame 3, and a connecting pipe 31 is installed on the outer surface of both counterweight tubes 30. The two counterweight tubes 30 are connected to the connecting pipe 31 to form a communicating vessel, thereby proportionally increasing the weight on the two counterweight platforms 6. The weight of the two auxiliary weighing devices 35 is then observed. When the weight difference between the foliar fertilizer nutrient solution container and the growth regulator container is equal to the weight difference between the two ends of the agricultural plant protection drone device 1, the weight of the growth regulator container is increased to ensure that the weights at both ends are consistent. The water flow from valve 36 is adjusted to ensure that water is released simultaneously when the agricultural plant protection drone device 1 sprays the foliar fertilizer nutrient solution and the growth regulator, maintaining a reasonable weight difference between the two ends of the device after spraying. The two main weighing devices 5 are used to weigh the foliar fertilizer nutrient solution container and the growth regulator container respectively. The material containers are weighed, and liquid is added to one of the counterweight pipes 30 according to the weight difference between the two to ensure that the weight of both ends of the drone device is consistent before spraying. The two counterweight pipes 30 are connected by a connecting pipe 31 to form a communicating vessel, achieving proportional weighting and further enhancing the accuracy of the counterweight. The agricultural plant protection drone device 1 with consistent weight is more stable during flight, reducing flight deviations and safety hazards caused by uneven weight. The foliar fertilizer nutrient solution and growth regulator are sprayed simultaneously, improving spraying efficiency and ensuring that crops can receive both nutrients at the same time. By adjusting the water output of valve 36, the agricultural plant protection drone device 1 can dynamically maintain the balance of weight at both ends during spraying. As the foliar fertilizer nutrient solution and growth regulator are sprayed, the weight of the foliar fertilizer nutrient solution container and the growth regulator container gradually decreases. The synchronous water release design ensures that the weight difference between the two ends of the agricultural plant protection drone device 1 is always kept within a reasonable range. The synchronous spraying and dynamic balance greatly improve the operating efficiency of the agricultural plant protection drone device 1 and reduce the time wasted on adjusting weight and spray volume.

[0035] Both counterweight tubes 30 are equipped with injection ports 32, and both counterweight tubes 30 are equipped with outlet pipes 33 on their outer surfaces. A valve 36 is installed inside one of the outlet pipes 33. A pipe plug 34 is movably installed on the inner wall of both injection ports 32. The two counterweight tubes 30 are connected to the connecting pipe 31 to form a connecting device, thereby increasing the weight on the two counterweight platforms 6 in proportion.

[0036] The multi-specification fixing component includes a handle column 7 and several retaining rings 8. The handle column 7 is movably installed inside the material carrying frame 3. The retaining rings 8 are evenly installed on the outer surface of the handle column 7. The outer surface of the retaining rings 8 is in contact with the interior of the material carrying frame 3. The operator rotates the handle column 7 with an Allen wrench. The handle column 7 drives the retaining rings 8 to rotate, thereby stably driving the small bevel gear 10 to rotate.

[0037] A small bevel gear 10 is mounted on one end surface of the handle column 7. A chuck base 9 is movably mounted inside the material carrying frame 3. A large bevel gear 11 is mounted on the inner surface of the chuck base 9. The outer surface of the small bevel gear 10 meshes with the outer surface of the large bevel gear 11, thereby driving the large bevel gear 11 to rotate. The large bevel gear 11 drives the chuck base 9 to rotate, and the chuck base 9 drives the progressive threaded bar 12 to rotate synchronously.

[0038] The bottom surface of the chuck base 9 is equipped with a progressive threaded strip 12. The outer surface of the material carrier frame 3 is provided with four moving grooves 13. Each of the four moving grooves 13 has a locking block 14 movably installed on its inner wall. Each of the four locking blocks 14 has a progressive threaded groove 15 on its bottom surface. The outer surface of the progressive threaded strip 12 is in contact with the inner wall of the progressive threaded groove 15. One end of each of the four locking blocks 14 is fixedly connected to the outer surface of the lower extrusion plate 16. The progressive threaded strip 12 extrudes the inner wall of the progressive threaded groove 15 at the bottom of the locking block 14, thereby causing the four locking blocks 14 to move within the moving grooves 13. This causes the four locking blocks 14 to move the lower extrusion plate 16, and the four lower extrusion plates 16 cause the sponge sleeve 17 to fix the bottom of the foliar fertilizer nutrient solution carrier container.

[0039] The medicine box and fixing assembly includes two guide posts 18 and a connecting block 19. The two guide posts 18 are movably installed inside the material carrying frame 3. The connecting block 19 is installed on one end surface of the two guide posts 18. The outer surface of the connecting block 19 is in movable contact with the outer surface of the upper extrusion plate 29. The material carrying frame 3 has a threaded groove 22 inside. A hexagonal threaded nail 21 is movably installed on the inner wall of the threaded groove 22. A rubber sleeve 20 is installed on one end surface of the hexagonal threaded nail 21. By rotating the hexagonal threaded nail 21 with an Allen wrench, the hexagonal threaded nail 21 is screwed into the threaded groove 22. The hexagonal threaded nail 21 drives the rubber sleeve 20 and the push plate 24 to move.

[0040] A push plate 24 is installed on the outer surface of the rubber sleeve 20. A through groove 23 is opened inside the upper extrusion plate 29. One end surface of the push plate 24 is in movable contact with one end surface of the connecting block 19. Two fixed columns 25 are installed inside the material frame 3. Each fixed column 25 has a telescopic cavity 26. A connecting spring 27 is installed inside the two telescopic cavities 26. A movable column 28 is installed on one end surface of each connecting spring 27. The outer surface of the movable column 28 is in movable contact with the inner wall of the telescopic cavity 26. One end surface of the movable column 28 is fixedly connected to one end surface of the connecting block 19. The rubber sleeve 20 extrudes the sponge sleeve 17 and the outer top of the foliar fertilizer nutrient solution container through the through groove 23. The push plate 24 pushes the connecting block 19 simultaneously. The connecting block 19 drives the limiting column and the movable column 28 to move, so that the connecting block 19 moves stably. The movable column 28 stretches the connecting spring 27. The remaining hexagonal threaded nails 21 are operated in sequence, so that the outer top of the foliar fertilizer nutrient solution container is extruded and fixed.

[0041] The workflow of this invention is as follows: When it is necessary to spray foliar fertilizer nutrient solution and growth regulator on crops, the foliar fertilizer nutrient solution carrier container and the growth regulator carrier container are placed into the carrier container cavity 2 inside the carrier frame 3. However, the volume of the foliar fertilizer nutrient solution being sprayed is greater than the volume of the growth regulator, resulting in the foliar fertilizer nutrient solution carrier container and the growth regulator carrier container having different specifications. The operator rotates the handle column 7 with an Allen wrench. The handle column 7 drives several retaining rings 8 to rotate the column, thereby stably driving the small bevel gear 10 to rotate. The small bevel gear 10... The outer surface meshes with the outer surface of the large bevel gear 11, thereby driving the large bevel gear 11 to rotate. The large bevel gear 11 drives the chuck base 9 to rotate, and the chuck base 9 drives the progressive threaded bar 12 to rotate synchronously. The progressive threaded bar 12 squeezes the inner wall of the progressive threaded groove 15 at the bottom of the locking block 14, thereby causing the four locking blocks 14 to move in the corresponding moving groove 13. This causes the four locking blocks 14 to drive the lower extrusion plate 16 to move, and the four lower extrusion plates 16 drive the sponge sleeve 17 to fix the bottom of the foliar fertilizer nutrient solution carrier container.

[0042] Furthermore, by rotating the hexagonal threaded nail 21 with an Allen wrench, the hexagonal threaded nail 21 is screwed into the inner groove 22 of the thread. The hexagonal threaded nail 21 drives the rubber sleeve 20 and the push plate 24 to move. The rubber sleeve 20 squeezes the outer top of the sponge sleeve 17 and the foliar fertilizer nutrient solution container through the through groove 23. At the same time, the push plate 24 pushes the connecting block 19 to move. The connecting block 19 drives the limiting post and the movable post 28 to move, so that the connecting block 19 moves stably. The movable post 28 stretches the connecting spring 27. The remaining hexagonal threaded nails 21 are operated in sequence to squeeze and fix the outer top of the foliar fertilizer nutrient solution container.

[0043] Four locking blocks 14 synchronously drive the lower extrusion plate 16 and the sponge sleeve 17 to move. The hexagonal threaded nail 21 drives the upper extrusion plate 29 and the sponge sleeve 17 to move through the connecting block 19, thereby fixing different specifications of material containers. It can also fix the four top sides of the material containers, preventing the foliar fertilizer nutrient solution container and the growth regulator container from falling off due to shaking during transportation and spraying when the agricultural plant protection drone device 1 is used. It can effectively fix the containers within the limited internal space of the material frame 3, and can adapt to a variety of different sizes and shapes of material containers. There is no need to customize specific fixing devices for each specification of container, which improves work efficiency. It can fix containers of different specifications, thereby making more effective use of storage space. Whether the container is large or small, it can be stably fixed, avoiding space waste caused by different container sizes.

[0044] Because the foliar fertilizer nutrient solution container is heavier than the growth regulator container, the agricultural plant protection drone device 1 sprays the foliar fertilizer nutrient solution and growth regulator in equal proportions to maintain a constant weight ratio. Two main weighing devices 5 weigh the foliar fertilizer nutrient solution container and the growth regulator container respectively. Based on the weight difference, liquid is added to one of the counterweight pipes 30 for counterweighting. The two counterweight pipes 30 are connected to a connecting pipe 31 to form a communicating vessel, thus proportionally increasing the weight on the two counterweight platforms 6. The two auxiliary weighing devices are then observed. When the weight of the weighing device 35 equals the difference between the weight of the foliar fertilizer nutrient solution container and the weight of the growth regulator container, the weight is increased on the growth regulator container side, thus ensuring that the weight at both ends of the agricultural plant protection drone device 1 is consistent. The water flow from valve 36 is adjusted to ensure that the agricultural plant protection drone device 1 releases water synchronously when spraying foliar fertilizer nutrient solution and growth regulator, maintaining a reasonable weight difference between the two ends of the agricultural plant protection drone device 1 after spraying. This is achieved by using two main weighing devices 5 to weigh the foliar fertilizer nutrient solution container and the growth regulator container respectively. The long regulator container is weighed, and liquid is added to one of the counterweight pipes 30 according to the weight difference between the two to ensure that the weight of the two ends of the drone device is consistent before spraying. The two counterweight pipes 30 are connected by a connecting pipe 31 to form a communicating vessel, realizing proportional weighting and further enhancing the accuracy of weight distribution. The agricultural plant protection drone device 1 with consistent weight is more stable during flight, reducing flight deviation and safety hazards caused by uneven weight. The foliar fertilizer nutrient solution and growth regulator are sprayed simultaneously, improving spraying efficiency and ensuring that crops can receive both nutrients at the same time. By adjusting the water output of valve 36, the agricultural plant protection drone device 1 can dynamically maintain the weight balance at both ends during spraying. As the foliar fertilizer nutrient solution and growth regulator are sprayed, the weight of the foliar fertilizer nutrient solution container and the growth regulator container gradually decreases. The synchronous water release design ensures that the weight difference between the two ends of the agricultural plant protection drone device 1 is always kept within a reasonable range. The synchronous spraying and dynamic balance greatly improve the operating efficiency of the agricultural plant protection drone device 1 and reduce the time wasted on adjusting weight and spray volume.
