Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sowing tools, in particular to a sowing drone. Background Art
[0002] Amid the rapid development of modern agricultural technology, drone seeding, as an efficient and precise agricultural method, is gaining increasing attention from farmers and agricultural enterprises. Traditional manual seeding methods are not only labor-intensive and inefficient, but also difficult to ensure uniformity and precision, especially when operating over large farmland areas. While existing drone seeding technology has improved seeding efficiency to a certain extent, it still faces some pressing challenges.
[0003] First, some drone seeding equipment often experiences blockages during the seeding process due to poor seed or granular fertilizer delivery, resulting in uneven seeding and affecting crop growth and yield. This is mainly due to the unreasonable design of the feeding mechanism, which is unable to effectively break the equilibrium state of the seeds, making it impossible for the seeds to enter the delivery device smoothly. Secondly, existing seeding drones mostly use a free fall method when delivering seeds. Although this method is simple, the seeds are easily offset when affected by airflow, resulting in inaccurate sowing positions and affecting the sowing effect. This effect is particularly significant in windy environments. Furthermore, the control of sowing density is also a difficult problem facing current drone sowing technology. Different crops have different requirements for sowing density, and existing drone sowing equipment often lacks a flexible adjustment mechanism and cannot meet diverse planting needs. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the utility model provides a seeding drone, which has the advantages of smooth and uniform material feeding and solves the problem of lack of an adjustment mechanism for seeding density.
[0005] The utility model provides the following technical solutions: a seeding drone, comprising a drone body and a turntable, the outer ring of the turntable is rotatably installed with four groups of evenly distributed material-throwing barrels, the lower middle part of the turntable is fixedly installed with an electric push rod, the lower end of the electric push rod is fixedly installed with a lifting plate, the outer ring of the lifting plate is fixedly installed with four groups of evenly distributed rotating parts, the lifting plate is rotatably connected to the material-throwing barrel through the rotating parts, a hopper is provided in the middle part of the interior of the drone body, the inner wall of the hopper is fixedly connected with a circular rail near the lower side, the interior of the circular rail is rotatably installed with a chassis, the material-throwing barrel is fixedly connected with an evenly distributed first sub-barrel near the middle, the material-throwing barrel is fixedly connected with an evenly distributed second sub-barrel near the lower side, and the interior of the material-throwing barrel is fixedly installed with a conical component near the lower end opening.
[0006] Furthermore, a rubber tube is provided between the upper end of the material throwing barrel and the chassis, and the material throwing barrel is connected to the silo through the rubber tube.
[0007] Furthermore, the first sub-barrel and the second sub-barrel are both connected to the material throwing barrel, and the angle between the first sub-barrel and the material throwing barrel is greater than the angle between the second sub-barrel and the material throwing barrel.
[0008] Furthermore, the inner wall of the silo is fixedly connected to six groups of evenly distributed fixing rods on the upper side of the circular rail, and a fixing plate is fixedly installed at the center of the corresponding chassis between the six groups of fixing rods, and a driving motor is fixedly installed on the upper end of the fixing plate.
[0009] Furthermore, a transmission shaft is fixedly installed on the lower output end of the driving motor, the transmission shaft passes through the chassis and is fixedly connected, and the lower end of the transmission shaft is fixedly connected to the turntable.
[0010] Furthermore, the lower end of the turntable is fixedly connected to four groups of evenly distributed guide rods near the chassis, and the lower ends of the guide rods are all passed through and slidably connected to the interior of the lifting plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The innovatively designed unloading and delivery mechanism of the seeding drone of this utility model significantly improves the uniformity and efficiency of sowing. Specifically, through the synchronous rotation of the turntable, chassis and throwing barrel, combined with the breaking of the seed balance state by the fixed rod, it ensures that the seeds can smoothly pass through the rubber tube into the throwing barrel, effectively avoiding the common blockage problem in the traditional unloading mechanism. In addition, due to the inertia effect and the guidance of the conical component inside the throwing barrel, the seeds achieve more uniform dispersion and wall-adhering movement, and are finally accurately thrown out through the sub-barrels with different opening angles, which greatly enhances the initial acceleration of the seeds, effectively reduces the influence of the airflow on the sowing position, and ensures the accuracy and uniformity of sowing.
[0013] 2. The utility model seeding drone is also highly flexible and adjustable, and can meet diverse planting needs. By driving the lifting plate up and down with an electric push rod and combining it with the limiting function of the rotating parts, the staff can easily adjust the opening and closing angles of the throwing barrel, thereby achieving precise control of the seeding density. This function is of great significance in practical applications. It allows farmers to flexibly adjust the seeding density according to factors such as soil conditions, crop types and planting goals, optimize crop layout, and improve land utilization and crop yield.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figure 1-Figure 4A seeding drone includes a drone body 1 and a turntable 2. The outer ring of the turntable 2 is rotatably mounted with four groups of evenly distributed throwing barrels 3. An electric push rod 4 is fixedly mounted at the middle of the lower end of the turntable 2. A lifting plate 5 is fixedly mounted at the lower end of the electric push rod 4. The outer ring of the lifting plate 5 is fixedly mounted with four groups of evenly distributed rotating parts 6. The lifting plate 5 is rotatably connected to the throwing barrel 3 through the rotating parts 6. A silo 7 is provided in the middle of the interior of the drone body 1. The inner wall of the silo 7 is fixedly connected with a circular rail 8 near the lower side. The inner rotation of the rail 8 is equipped with a chassis 9, and the first sub-tube 11 is fixedly connected to the material throwing barrel 3 near the middle, and the second sub-tube 12 is fixedly connected to the material throwing barrel 3 near the lower side. The inner part of the material throwing barrel 3 is fixedly equipped with a cone component 13 near the lower end opening. After the drive motor 16 is remotely opened, the transmission shaft 17 is driven to rotate. The rotation of the transmission shaft 17 can eventually drive the turntable 2, the chassis 9 and the lifting plate 5 to rotate, thereby synchronously driving the material throwing barrel 3 to rotate, and the chassis 9 When the seeds rotate, the fixed rod 14 can better break the balance of the seeds, so that the seeds can enter the interior of the throwing barrel 3 through the rubber tube 10, and the seeds will move downward due to the rotation and angle of the throwing barrel 3 and the rubber tube 10, and the rubber tube 10 serving as the discharge port will not be blocked. Furthermore, when the seeds move downward due to inertia inside the four groups of throwing barrels 3 distributed in a circular shape, some seeds will enter the interior of the first sub-barrel 11 and the second sub-barrel 12, and the remaining seeds will be more dispersedly attached to the inner wall of the throwing barrel 3 due to the action of the conical component 13 when moving to the lower outlet of the throwing barrel 3, and the opening angle of the first sub-barrel 11 is greater than that of the second sub-barrel 12, so that the seeds that are finally thrown downward can fall more evenly into the field. At the same time, compared with the sowing drone using free fall, the seeds sown by this device are equivalent to having an initial acceleration, which will ideally reduce the influence caused by airflow under the blessing of gravity, thereby ensuring the uniformity of sowing.
[0021] See also Figure 3 A rubber tube 10 is provided between the upper end of the throwing barrel 3 and the chassis 9. The throwing barrel 3 is connected to the silo 7 through the rubber tube 10. Since the throwing barrel 3 is displaced when the angle is adjusted, the rationality of the structure is ensured by the deformation of the rubber tube 10.
[0022] See also Figure 3-Figure 4The first sub-cylinder 11 and the second sub-cylinder 12 are both connected to the throwing barrel 3, and the angle between the first sub-cylinder 11 and the throwing barrel 3 is greater than the angle between the second sub-cylinder 12 and the throwing barrel 3. The inner wall of the silo 7 is fixedly connected with six groups of evenly distributed fixing rods 14 at the upper side of the circular rail 8. A fixing plate 15 is fixedly installed between the six groups of fixing rods 14 at the center of the corresponding chassis 9. The upper end of the fixing plate 15 is fixedly installed with a driving motor 16, and the lower end output end of the driving motor 16 is fixedly installed with a transmission shaft 17. The transmission shaft 17 passes through the chassis 9 and is fixedly connected. The lower end of the transmission shaft 17 is fixedly connected to the turntable 2 by opening the electric push rod 4. The lifting plate 5 can be driven to rise and fall. The lifting plate 5 is lifted and lowered and the limiting effect of the rotating member 6 can be used to adjust the opening and closing angle of the throwing barrel 3 at a certain angle, so that the staff can adjust it according to the actual planting needs, thereby achieving the control of sowing density and improving the flexibility and sowing effect of the device when in use.
[0023] See also Figure 3 The lower end of the turntable 2 is fixedly connected with four groups of evenly distributed guide rods 18 near the chassis 9. The lower ends of the guide rods 18 pass through and are slidably connected to the inside of the lifting plate 5. The guide rods 18 improve the structural strength between the turntable 2 and the lifting plate 5, ensure its stability during rotation, and avoid damage to the electric push rod 4 due to overload.
[0024] Working principle: After pouring seeds or granular fertilizers into the silo 7, the drone body 1 is controlled by the remote control device to perform the sowing operation. The drive motor 16 is remotely turned on to drive the transmission shaft 17 to rotate. The rotation of the transmission shaft 17 can eventually drive the turntable 2, the chassis 9 and the lifting plate 5 to rotate, thereby synchronously driving the throwing barrel 3 to rotate. When the chassis 9 rotates, the seeds on the chassis 9 can better break the balance of the seeds due to the influence of the fixed rod 14, so that the seeds can enter the interior of the throwing barrel 3 through the rubber tube 10. Further, When the seeds move downward due to inertia inside the four groups of circularly distributed throwing barrels 3, some seeds will enter the first sub-barrel 11 and the second sub-barrel 12, and the remaining seeds will be more dispersedly attached to the inner wall of the throwing barrel 3 due to the action of the conical component 13 when moving to the lower outlet of the throwing barrel 3, and the opening angle of the first sub-barrel 11 is greater than that of the second sub-barrel 12. In addition, by turning on the electric push rod 4, the lifting plate 5 can be driven to rise and fall. Through the lifting and lowering of the lifting plate 5 and the limiting action of the rotating part 6, the opening and closing angle of the throwing barrel 3 can be adjusted at a certain angle.
