[0001] This utility model relates to the field of seeding device technology, specifically a seeding device for agricultural drones. Background Technology

[0002] Unmanned agriculture refers to agricultural production processes that are fully operated and controlled through agricultural drones, unmanned vehicles, and satellite positioning systems. Currently, when drones are used for sowing, seeds are generally sown directly using a sowing roller. A search reveals that Chinese Patent Publication No. CN221598635U discloses a sowing device for agricultural drones, belonging to the field of drone technology. This sowing device includes a drone body, a base frame fixedly connected to the lower part of the drone body, a bonding frame fixedly installed below the base frame, a sowing box located below the bonding frame, a motor fixedly installed on one side of the sowing box, a limit rod inserted into the inner side of the bonding frame, a mounting base fixedly connected to the upper part of the sowing box, a feed inlet on one side of the mounting base, and a sowing mechanism fixedly installed inside the sowing box.

[0003] Although the above technical solution can spread seeds evenly and ensure uniformity of seed fall by setting up three sets of seeding mechanisms with the same spacing, the fixed distance between the seeds makes it inconvenient to adjust according to different situations. Furthermore, the seeds are easily blown away by the wind after falling, which affects the seeding accuracy. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] like Figures 1 to 4 As shown, a seeding device for an agricultural drone includes a storage box 1 for placing seeds. Three feeding hoppers 2 are fixedly connected to the bottom of the storage box 1. A support 3 is fixedly connected to the bottom of the storage box 1. A seeding mechanism 4 that cooperates with the feeding hoppers 2 is installed inside the support 3. The seeding mechanism 4 includes a spline shaft 41 rotatably connected inside the support 3. Three seeding discs 42 are sequentially sleeved on the spline shaft 41. The seeding discs 42 on both sides are slidably connected to the spline shaft 41. The seeding disc 42 in the middle is fixedly installed on the spline shaft 41. A box 43 is rotatably sleeved on the outer side of each of the three seeding discs 42. A feeding hose 44 is fixedly connected between the top of the box 43 on both sides and the feeding hoppers 2 on both sides. A connecting pipe 45 is fixedly connected between the box 43 in the middle and the feeding hopper 2 in the middle. Multiple receiving grooves 46 are sequentially opened on the outer surface of the seeding discs 42. A motor 47 is fixedly installed on one side of the support 3. The output shaft of the motor 47 is fixedly connected to one end of the spline shaft 41.

[0024] Seeds enter the receiving trough 46 on the seeding tray 42 through the corresponding connecting pipe 45 and the feeding hose 44. The motor 47 rotates, driving the spline shaft 41 and the seeding tray 42 to rotate, thus rotating the seeds.

[0025] like Figures 1 to 3As shown, the bracket 3 is equipped with an adjustment mechanism 5 that cooperates with the sowing mechanism 4. The adjustment mechanism 5 includes a bidirectional screw 51 that is rotatably connected through the bracket 3. The outer surface of the bidirectional screw 51 is symmetrically threaded with two connecting blocks 52. The two connecting blocks 52 are fixedly connected to one side of the box 43 on both sides respectively. A knob 53 is fixedly connected to one end of the bidirectional screw 51.

[0026] Rotating the knob 53 drives the bidirectional screw 51 to rotate, which in turn drives the connecting blocks 52 on both sides and the corresponding box 43 to move relative to each other through the thread, thereby changing the distance between the seeds.

[0027] like Figures 1 to 5 As shown, a flow guiding mechanism 6 is installed between the two sides of the storage box 1 to cooperate with the sowing mechanism 4. The flow guiding mechanism 6 includes a fixed tube 61 fixedly connected to the bottom of the box body 43, a movable tube 62 sliding on the outer surface of the fixed tube 61, a limit block 63 fixedly connected to one side of the movable tube 62, an electric push rod 64 fixedly installed on both sides of the storage box 1, a connecting plate 65 fixedly connected between the bottom ends of the electric push rod 64, and a limit groove 66 slidably connected to the limit block 63 on one side of the connecting plate 65.

[0028] The operation of the electric push rod 64 can drive the connecting plate 65 to move up and down. With the cooperation of the limiting block 63 and the limiting groove 66, it can drive the movable tube 62 to move down. The seeds fall from the fixed tube 61 and the movable tube 62, which can change the distance of the seed exposed in the air, thereby reducing the impact of wind on the seeds and improving the accuracy of sowing.

[0029] In this technical solution, a distance sensor can also be installed on the connecting plate 65 to detect the real-time distance between the movable tube 62 and the ground.

[0030] In this technical solution, a controller is installed on one side of the storage box 1. The distance sensor, motor 47 and electric push rod 64 are all connected to the controller through wires. Controlling by the controller is a common technical means used by those skilled in the art and belongs to the prior art.

[0031] A feeding pipe 7 is fixedly connected to one side of the storage box 1 for easy addition of seeds.

[0032] The top of the storage box 1 is symmetrically and fixedly connected to two mounting brackets 8 for fixing the storage box 1 to the drone. The outer surface of the mounting brackets 8 is provided with mounting holes to facilitate the installation of the device on the drone.

[0033] Working principle: Seeds enter the receiving groove 46 on the sowing tray 42 through the corresponding connecting pipe 45 and the feeding hose 44. The motor 47 rotates, driving the spline shaft 41 and the sowing tray 42 to rotate, which in turn drives the seeds to rotate. The electric push rod 64 can drive the connecting plate 65 to move up and down. With the cooperation of the limiting block 63 and the limiting groove 66, the movable tube 62 can be driven to move downward. The seeds fall from the fixed tube 61 and the movable tube 62, which can change the distance of the seed exposed in the air, thereby reducing the impact of wind on the seeds and improving the sowing accuracy.

[0034] Rotating the knob 53 drives the bidirectional screw 51 to rotate, which in turn drives the connecting blocks 52 on both sides and the corresponding box 43 to move relative to each other through the thread, thereby changing the distance between the seeds.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
