[0001] This invention relates to the field of agricultural drones, and more specifically, to a seeding system and a drone. Background Technology

[0002] Agricultural drones are developing rapidly, with continuously increasing payload capacity, enabling their application in more and more aspects of field agricultural production. In field management of field crops, drones are used not only for spraying liquid pesticides but also for spreading granules such as seeds, powders, and solid fertilizers. To enable drones to spread seeds, powders, and solid fertilizers, spreading devices are mounted on the drones.

[0003] Existing seeding devices suffer from uneven seeding and poor seeding efficiency. Summary of the Invention

[0004] This invention provides a seeding system and a drone that can ensure more uniform seeding, thereby improving seeding quality and efficiency.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] Embodiments of the present invention provide a dispersing system, comprising:

[0007] Material conveying device;

[0008] A swivel disc is oscillatingly mounted on the conveying device. The center of the discharge end of the conveying device and the oscillation center of the swivel disc are offset. The swivel disc is used to spread materials outward while oscillating back and forth.

[0009] Optionally, the material conveying device includes a hopper and a drive auger. The drive auger is located at the outlet of the hopper, and the end of the drive auger is the discharge end. The drive auger conveys the material to the slinger when it rotates.

[0010] Optionally, the vertical distance between the center of the discharge end and the swing center of the swivel disc ranges from 18mm to 24mm.

[0011] Optionally, the horizontal distance between the center of the discharge end and the swing center of the swivel disc is 7mm-8mm.

[0012] Optionally, the slinger includes a mounting body and multiple blades, the multiple blades being spaced apart along the circumferential direction on the mounting body, the center of the mounting body being the swing center, and the mounting body being used to make the blades contact the material when swinging back and forth, thereby spreading the material outward.

[0013] Optionally, the center of the discharge end is located above the swing center of the swivel disc.

[0014] Optionally, the spreading system further includes a driving component and a transmission component, the driving component and the transmission component being connected, the transmission component being connected to the spinning disc, and the transmission component being used to drive the spinning disc to swing back and forth under the drive of the driving component, thereby spreading outward.

[0015] Optionally, the transmission component is a crank-rocker structure.

[0016] Optionally, the spreading system further includes a housing that covers the spinning disc.

[0017] Optionally, the swing center of the swivel disc is located at the lower right corner of the discharge end, the driving auger includes multiple right-handed blades, the multiple right-handed blades are arranged in a circumferential direction, and the rotation direction of the driving auger is clockwise.

[0018] Alternatively, the swing center may be located at the lower left corner of the discharge end, the driving auger may include multiple left-handed blades arranged in a circumferential direction, and the driving auger may rotate in a counterclockwise direction.

[0019] Embodiments of the present invention also provide a drone, including a fuselage and a dispersing system, wherein the dispersing system is mounted on the fuselage.

[0020] The beneficial effects of the seeding system and drone of the present invention include, for example:

[0021] This spreading system includes a conveying device and a swivel disc. The swivel disc is oscillatingly mounted on the conveying device, with the center of the discharge end of the conveying device offset from the oscillation center of the swivel disc. The swivel disc is used to spread material outwards during its back-and-forth oscillation. In use, the swivel disc is oscillatingly mounted on the conveying device, allowing material inside the conveying device to enter the swivel disc through its discharge end. The oscillation of the swivel disc spreads the material outwards. The offset between the center of the discharge end of the conveying device and the oscillation center of the swivel disc compensates for uneven material discharge from the conveying device, resulting in more uniform material discharge and improved spreading uniformity, thus enhancing spreading quality and efficiency.

[0022] The drone includes a fuselage and a spreading system mounted on the fuselage. In use, the spreading system features a swinging disc mounted on a conveying device. Material inside the conveying device enters the spreading disc through the discharge end. As the disc swings back and forth, it spreads the material outwards. The center of the discharge end of the conveying device and the swing center of the spreading disc are misaligned to compensate for uneven material discharge from the conveying device. This more uniform material discharge improves the spreading uniformity of the spreading disc, thereby enhancing spreading quality and efficiency. Attached Figure Description

[0033] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0034] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0035] Agricultural drones are developing rapidly, with continuously increasing payload capacity, enabling their application in more and more aspects of field agricultural production. In field management of field crops, drones are used not only for spraying liquid pesticides but also for spreading granules such as seeds, powders, and solid fertilizers. To enable drones to spread seeds, powders, and solid fertilizers, spreading devices are mounted on the drones.

[0036] The seeding devices in related technologies suffer from technical problems such as uneven seeding and poor seeding efficiency.

[0037] Please refer to Figures 1-4 This embodiment provides a drone, which includes a fuselage and a seeding system 100. The seeding system 100 is mounted on the fuselage and can perform seeding operations while the drone is in flight. This drone can effectively improve the aforementioned technical problems, ensuring more uniform seeding and improving seeding quality and efficiency.

[0038] In this embodiment, the carrier is a drone, specifically an agricultural drone, which is generally equipped with spraying and sowing components required for agriculture, enabling spraying irrigation, sowing, and other functions. Of course, the carrier can also carry cameras, gaming devices, etc. Furthermore, the carrier is not limited to drones; for example, it can also be a robot, an unmanned vehicle, or an unmanned boat.

[0039] Please refer to Figures 1-2 This embodiment provides a spreading system 100 including a material conveying device 10 and a swivel disc 20. The swivel disc 20 is swivelly disposed on the material conveying device 10. The center of the discharge end 101 of the material conveying device 10 and the swing center 201 of the swivel disc 20 are misaligned. The swivel disc 20 is used to spread materials outward while swinging back and forth.

[0040] In this embodiment, the back-and-forth swing of the sling plate 20 means that the sling plate 20 can swing back and forth to throw the material out from the left and right swing direction. The sling plate 20 spreads the material with a large amplitude, which can reduce the number of times the drone flies and improve the spreading efficiency.

[0041] More specifically, the swing plate 20 can swing back and forth on both sides in the vertical direction. Of course, the swing plate 20 is not limited to swinging back and forth on both sides in the vertical direction; it can also be set to swing back and forth on both sides in the horizontal or inclined direction, without specific limitations here.

[0042] Specifically, existing material conveying devices suffer from uneven material discharge at the outlet, leading to uneven spreading of materials and poor spreading quality. To address this issue, the spreading system 100 provided in this embodiment features a swing-displacement disc 20 mounted on the material conveying device 10. Material inside the material conveying device 10 enters the swing-displacement disc 20 through the outlet 101. As the disc 20 swings back and forth, it spreads the material outwards. The center of the outlet 101 of the material conveying device 10 and the swing center 201 of the disc 20 are misaligned, which counteracts the uneven material discharge at the outlet 101 of the material conveying device 10. This more uniform material discharge improves the spreading uniformity of the disc 20, thereby enhancing spreading quality and efficiency.

[0043] In this embodiment, the material conveying device 10 includes a hopper 11 and a drive auger 12. The drive auger 12 is located at the outlet of the hopper 11, and the end of the drive auger 12 is the outlet end 101. When the drive auger 12 rotates, it conveys the material to the sling plate 20.

[0044] Specifically, the hopper 11 is located at the bottom of the machine body, and the feed inlet of the hopper 11 can be located on the side of the machine body for easy feeding. The drive auger 12 is located at the discharge port of the hopper 11, which is below the feed inlet. The material in the hopper 11 can fall into the drive auger 12 under the action of gravity, and the drive auger 12 rotates, thereby conveying the material to the discharge end 101, so that the material enters the sling plate 20.

[0045] Furthermore, the conveying device 10 also includes a conveying motor, which is connected to the end of the drive auger 12 away from the discharge end 101. The conveying motor drives the drive auger 12 to rotate, thereby transporting the material.

[0046] Please refer to Figure 3 The vertical distance between the center of the discharge end 101 and the swing center 201 of the swivel disc 20 is 18mm-24mm, and the horizontal distance between the center of the discharge end 101 and the swing center 201 of the swivel disc 20 is 7mm-8mm.

[0047] In this embodiment, the vertical distance between the center of the discharge end 101 and the swing center 201 of the swivel disc 20 is 20 mm. The horizontal distance between the center of the discharge end 101 and the swing center 201 of the swivel disc 20 is 7.5 mm. In other embodiments, the vertical distance between the center of the discharge end 101 and the swing center 201 of the swivel disc 20 can be 18 mm, 19 mm, 23 mm, or 24 mm. The horizontal distance between the center of the discharge end 101 and the swing center 201 of the swivel disc 20 can be 7 mm, 7.3 mm, or 8 mm. No specific limitation is made here.

[0048] from Figure 3 As can be seen from the specific structure, the swing center 201 of the swivel disc 20 is located at the lower right corner of the center of the discharge end 101 of the driving auger 12. Since the center of the discharge end 101 of the driving auger 12 and the swing center 201 of the swivel disc 20 are not on the same straight line, even if there is an uneven discharge problem in the driving auger 12, it can be offset by the staggered setting, thereby ensuring the uniformity of the spreading by the swivel disc 20 and improving the spreading quality. In other embodiments, the swing center 201 of the swivel disc 20 can also be located at the lower left corner of the center of the discharge end 101 of the driving auger 12, which is not specifically limited here.

[0049] Please refer to Figure 4 It should be noted that the slinger 20 includes a mounting body 21 and multiple blades 22. The multiple blades 22 are spaced apart on the mounting body 21 along the circumferential direction. The center of the mounting body 21 is the swing center 201. The mounting body 21 is used to make the blades 22 contact the material when swinging back and forth, thereby spreading the material outward.

[0050] Specifically, multiple blades 22 are arranged at intervals around the swing center 201 of the mounting body 21 in a circumferential direction, and a material drop space is formed between two adjacent blades 22. When the swivel disc 20 swings back and forth, the material comes into contact with the surface of the blades 22, thereby spreading it outward.

[0051] In this embodiment, the blade 22 has a rectangular structure, and there are eight blades 22. In other embodiments, the number of blades 22 may be increased or decreased, and no specific limitation is made here.

[0052] In this embodiment, all blades 22 are right-handed blades. Figure 3 In the view, the auger 12 is driven to rotate clockwise. In other embodiments, the blade 22 can be a left-handed blade, driving the auger 12 to rotate counterclockwise.

[0053] Furthermore, the seeding system 100 also includes a drive component 40 and a transmission component 30, which are connected to each other. The transmission component 30 is connected to the spinning disc 20, and the transmission component 30 is used to drive the spinning disc 20 to swing back and forth under the drive of the drive component 40, thereby spreading the seed outward. Specifically, the drive component 40 is a drive motor.

[0054] In this embodiment, the transmission component 30 is a crank-rocker structure. Specifically, the transmission component 30 includes a crank 31, a first connecting rod 32, and a second connecting rod 33. The two ends of the first connecting rod 32 are rotatably connected to the crank 31 and the second connecting rod 33, respectively. The end of the second connecting rod 33 away from the first connecting rod 32 is connected to the swing center 201 of the mounting body 21. The crank 31 is connected to the driving component 40 and can rotate around the drive shaft of the driving component 40, thereby driving the first connecting rod 32 to swing. The second connecting rod 33 can be limited relative to the mounting body 21 in the circumferential direction.

[0055] Specifically, a connecting flange is provided on the side of the mounting body 21 near the transmission component 30. The connecting flange can be fixed to the swing center 201 of the mounting body 21 by means of bolt connection or other methods.

[0056] More specifically, the length of the first link 32 is longer than the length of the second link 33.

[0057] Understandably, there are various mechanisms that can drive the swivel disc 20 to swing back and forth, and it is not limited to a linkage transmission mechanism. Other driving methods can also be used to drive the swivel disc 20 to swing back and forth. No specific limitation is made here.

[0058] It should also be noted that the seeding system 100 also includes a housing 50, which covers the seeding disc 20.

[0059] Specifically, the outer casing 50 includes a first casing and a second casing, which are detachably connected and together form a receiving space. The slinger 20 is disposed in the receiving space. The first casing has an opening, and the discharge end 101 of the drive auger 12 is disposed in the opening, so that the material at the discharge end 101 can enter the slinger 20 through the opening. The slinger 20 is oscillatingly mounted on the second casing. The slinger 20 and the transmission component 30 are respectively located on both sides of the second casing.

[0060] The seeding system 100 provided in this embodiment has at least the following advantages:

[0061] In existing technologies, the discharge end of the conveying device suffers from uneven material discharge, leading to uneven spreading of materials and poor spreading quality. To address this issue, the spreading system 100 provided in this embodiment features a swing-distributed disc 20 mounted on the conveying device 10. Material inside the conveying device 10 enters the disc 20 through the discharge end 101. As the disc 20 swings back and forth, it spreads the material outwards. The center of the discharge end 101 of the conveying device 10 and the swing center 201 of the disc 20 are misaligned, which counteracts the uneven material discharge from the discharge end 101 of the conveying device 10. This more uniform material discharge improves the spreading uniformity of the disc 20, thereby enhancing spreading quality and efficiency.

[0062] In summary, this invention provides a seeding system 100 and a drone. The seeding system 100 includes a material conveying device 10 and a spinning disc 20. The spinning disc 20 is oscillatingly mounted on the material conveying device 10. The center of the discharge end 101 of the material conveying device 10 and the swing center 201 of the spinning disc 20 are misaligned. The spinning disc 20 is used to spread materials outward while swinging back and forth. When in use, the spinning disc 20 is oscillatingly mounted on the material conveying device 10. The material inside the material conveying device 10 can enter the spinning disc 20 through the discharge end 101. As the spinning disc 20 swings back and forth, it can spread the material outward. The misalignment between the center of the discharge end 101 of the material conveying device 10 and the swing center 201 of the spinning disc 20 can compensate for the problem of uneven material discharge from the discharge end 101 of the material conveying device 10. More uniform material discharge improves the spreading uniformity of the spinning disc 20, thereby improving the spreading quality and efficiency.

[0063] The drone includes a fuselage and a spreading system 100, which is mounted on the fuselage. In use, the spreading system 100 has a swivel disc 20 mounted on a conveying device 10. Material inside the conveying device 10 enters the spreading disc 20 through the discharge end 101. As the spreading disc 20 oscillates back and forth, it spreads the material outwards. The center of the discharge end 101 of the conveying device 10 and the oscillation center 201 of the spreading disc 20 are misaligned, which compensates for uneven material discharge from the discharge end 101 of the conveying device 10. More uniform material discharge improves the spreading uniformity of the spreading disc 20, thereby improving spreading quality and efficiency.

[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
