Description

Technical Field

[0001] The present application relates to the technical field of monitoring equipment, and in particular to a large-particle fertilizer and pesticide spreading drone device for organic rice. Background Art

[0002] Drones can be used in agriculture for sowing, fertilizing, and spraying pesticides. They are widely used because they spray directly above the crops without damaging them and are highly efficient. Generally, liquid materials (such as pesticides) are pumped out of the silo using a compression pump and sprayed toward the bottom of the drone. Solid materials (such as seeds or fertilizer granules) require a pulse device to spray them directly into the soil. For solid fertilizer granules, there are restrictions on particle size for even spraying. This is because larger fertilizer granules will fall nearly vertically after leaving the drone's material port due to their own weight, resulting in a smaller single spraying range and an excessively high fertilizer density within the spraying area. This not only poses disadvantages to drone fertilization operations, but also increases the number of sprays per unit area, resulting in low economy and practicality. Utility Model Content

[0017] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, with reference to the accompanying drawings. Furthermore, the phrases "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0018] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity from another, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that an article or terminal device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such article or terminal device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the article or terminal device comprising the element.

[0019] like Figure 1 and Figure 2 As shown, the utility model provides a large-particle fertilizer and pesticide-spreading drone device for organic rice, the drone device includes at least four symmetrically arranged wings 1, the propeller is detachably connected to one end of the wing 1, and also includes a chassis 2 connected to one end of the wing 1; a material box for carrying granular fertilizer is provided in the chassis 2, the bottom of the chassis 2 includes multiple first discharge ports 3 and a second discharge port 4, and a conical retractable accordion base 6, the first discharge port 3 and the second discharge port 4 are independent of each other, the first discharge port 3 and the material box outlet of the chassis 2 are aligned in the vertical direction, the second discharge port 4 is evenly arranged on the periphery of the first discharge port 3, and a distributor is provided on the outside of the second discharge port 4, the distributor includes a movably connected distributor plate 5, and the angle α between the distributor plate 5 and the discharge direction of the second discharge port 4 changes according to a preset rate under the drive of the driving device, and the range of α is: 90°-180°; the chassis 2 also includes: a compression pump, which is docked with the second discharge port 4.

[0020] like Figure 2 As shown, in this embodiment, the actual fertilization range includes two angle ranges α and the area between the two angle ranges α. Specifically, the middle fertilization range is the fertilizer particles ejected from the first discharge port 3, and the ranges on both sides are ejected from the second discharge port 4. The granular fertilizer is rebounded to the area outside the fuselage under the action of the separator 5. The range of fertilization per flight is increased, so that the number of total fertilization flights of the drone provided by this embodiment is fewer than that of other drones within the same area, thereby reducing the cost of drone fertilization and making drone fertilization more economical.

[0021] In addition, it should be noted that the area of ​​fertilization can also be adjusted by adjusting the speed at which the granular fertilizer is sprayed out of the second discharge port 4, because the greater the speed at which the granular fertilizer collides with the dividing plate 5, the greater its kinetic energy, and the greater the horizontal distance it jumps outward after leaving the dividing plate 5; of course, the angle of the dividing plate directly affects the range spanned by the granular fertilizer. In actual use, the angle of the dividing plate 5 can be adjusted accordingly according to the speed of the fertilizer injection. In this embodiment, because the dividing plate 5 changes within a preset angle range, the fertilizer sprayed out at the same time can cover a rice field, rather than fertilizing a smaller area. The rate of change of the angle of the dividing plate 5 is related to the rate at which the drone flies and fertilizes. In practice, they need to be adjusted to each other so that at a certain flight speed, the granular fertilizer can cover the largest range of rice fields.

[0022] It should be noted that the retractable accordion base 6 supports the drone when it lands. Therefore, it is designed to be retractable. It opens when the drone lands to install the hopper and retracts when the drone takes off to begin fertilizing, thus preventing any disruption to fertilization. Furthermore, the accordion structure is more stable than existing support frames and cushions or evens out the impact of the drone landing, thus addressing any instability. Furthermore, the retractable accordion base 6 includes a support plate, which ensures the smooth contact of the accordion base with the ground and protects the accordion structure.

[0023] In some embodiments, the distributor further includes a motor connected to the mounting axis of the distributor plate 5, which drives the distributor plate 5 to rotate about the mounting axis. In this embodiment, the distributor plate 5 is configured to rotate about a predetermined axis, so that when the granular fertilizer contacts the distributor plate 5, the surface friction of the distributor plate 5 generates a tangential force, thereby changing the direction of fertilizer movement and further expanding the fertilization range.

[0024] In some embodiments, the aforementioned wing 1 comprises two sections, each foldable; the angle between one section of the wing 1 and the chassis 2 is adjustable. This structure increases the adjustment range of the wing 1, thereby increasing the total amount of fertilizer that the drone can carry, thereby achieving a capacity expansion effect.

[0025] In addition, in this embodiment, the cover and the body of the chassis 2 are streamlined. The streamlined structure can reduce the resistance of the drone during flight, thereby increasing the carrying capacity of the drone.

[0026] In some embodiments, the nozzle of the aforementioned first discharge port 3 is provided with a distribution net, which includes several discharge ports, each having a diameter 1.2 times the diameter of the granular material. The distribution net is provided to homogenize the fertilizer before it falls into the paddy field, preventing the granular fertilizer from being too dense. The mesh of the distribution net evenly distributes the granules. To ensure uniform distribution, the mesh diameter is set to 1.2 times the average diameter of the granular fertilizer, allowing the fertilizer to pass through the mesh with just enough room.

[0027] Finally, the utility model provides a large-particle fertilizer and pesticide-spreading drone device for organic rice, comprising at least four symmetrically arranged wings 1, the propellers being detachably connected to one end of the wings 1, and a chassis 2 connected to one end of the wing 1; a material box for carrying granular fertilizer is provided in the chassis 2, the bottom of the chassis 2 comprises multiple first discharge ports 3 and a second discharge port 4, and a conical retractable accordion base 6, the first discharge port 3 and the second discharge port 4 are independent of each other, the first discharge port 3 and the material box outlet of the chassis 2 are aligned in the vertical direction, the second discharge port 4 is evenly arranged on the periphery of the first discharge port 3, a distributor is provided on the outside of the second discharge port 4, the distributor comprises a movably connected distributor plate 5, the angle α between the distributor plate 5 and the discharge direction of the second discharge port 4 changes according to a preset rate under the drive of the driving device, and the range of α is: 90°-180°; the chassis 2 also includes: a compression pump, which is connected to the second discharge port 4. The utility model increases the spraying range of large-particle fertilizer applied to rice by using a drone, makes the fertilizer particles uniform, and improves the economy of drone fertilization.
