Description

Technical Field

[0001] This utility model relates to the field of wheat planting technology, specifically to a remote-controlled sowing drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by onboard computers, either completely or intermittently. They are widely used in various fields, but in the field of agricultural technology, the application of UAVs is still relatively limited. Most wheat seeds are still sown manually, which is not only labor-intensive but also inefficient, seriously affecting crop yields. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a remote seeding drone, comprising a drone body, a hopper and a seed box fixed to the inner side of the drone body by a support frame, the hopper frame being fixed to the top of the seed box and connected thereto, and a seeding block being rotatably connected to the inner side of the seed box, and a drive motor for driving the seeding block to rotate being installed on the outer side, with multiple seed slots opened on the outer side of the seeding block, and a baffle extending into the seed box and abutting the seeding block being fixed to the side wall of the hopper, and a lower seeding tube extending to the outer side of the drone body being fixed to the bottom of the seed box.

[0004] Furthermore, a stirring rod is rotatably connected to the inner side of the hopper, and a drive motor for driving the stirring rod to rotate is also installed on the outer side.

[0005] Furthermore, the drone body is also equipped with two sets of water tanks and two sets of hollow pipes on each side, and a pump body at the bottom that is connected to the water tanks and hollow pipes respectively. Multiple sprayers are installed on the outside of the hollow pipes.

[0006] Furthermore, a three-way pipe is fixed at the output end of the pump body, and water guide pipes connected to corresponding hollow pipes are fixed at both ends of the three-way pipe.

[0007] Furthermore, multiple guide tube frames are locked and fixed on the outside of the hollow tube, and the sprayer is installed at the bottom of the guide tube frame. The sprayer is connected to the hollow tube through a water supply pipe, and the water supply pipe passes through the guide tube frame.

[0008] Furthermore, the drone body and the hollow tube are connected by a tie rod.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] 1. The seed distribution blocks inside the seed box are equipped with multiple seed slots on the outside. Together with the baffles that extend from the side wall of the hopper into the seed box and are attached to the seed distribution blocks, the rotation speed of the seed distribution blocks can be controlled by the drive motor to achieve precise adjustment of the amount of seeds falling. The lower end of the seeding tube is sloped, which, combined with the flight speed of the drone, can make the seeds evenly spread to the ground and avoid the problem of uneven density in manual sowing.

[0011] 2. The water tanks on both sides of the drone are connected to the hollow tube through the pump body, T-pipe, and water guide pipe. The sprayer on the outside of the hollow tube is connected to the hollow tube through the water supply pipe. The water in the tank can be evenly sprayed to the sowing area while sowing, reducing the cumbersome process of sowing and watering in traditional operations and greatly improving the efficiency of operation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1-3This embodiment of a remote seeding drone includes a drone body 1. A hopper 3 and a seed box 7 are fixed to the inner side of the drone body 1 via a support frame 2. The hopper 3 is fixed to the top of the seed box 7 and connected to it. The hopper 3 and the seed box 7 are integrally formed and are used to temporarily store seeds and supply seeds to the seed box 7. A seed distribution block 6 is rotatably connected to the inner side of the seed box 7. A drive motor 9 for driving the seed distribution block 6 to rotate is installed on the outer side. Multiple seed slots are opened on the outer side of the seed distribution block 6. A baffle 5 extending into the seed box 7 and abutting the seed distribution block 6 is fixed to the side wall of the hopper 3. The baffle 5 is arc-shaped and its width is adapted to the width of the seed box 7. A lower seed tube 8 extending to the outer side of the drone body 1 is fixed to the bottom of the seed box 7.

[0018] In the above structure, seeds fall into the seed box through the connection between the hopper and the seed box. The seed distribution block rotates under the drive of the drive motor. When the seed trough carrying seeds passes through the baffle, the baffle blocks excess seeds and only allows the seeds in the seed trough to pass through, thus achieving quantitative seeding. The seeds rotate with the seed distribution block to the bottom of the seed box and are evenly sown to the ground through the seeding tube. The slope of the lower end of the seeding tube can further optimize the seed falling trajectory and ensure sowing uniformity.

[0019] The inner side of the hopper 3 is rotatably connected to a stirring rod 4 located at the opening of the seed box 7, and the outer side is equipped with a drive motor 9 that drives the stirring rod 4 to rotate, which is used to stir the seeds in the hopper and prevent clumping and blockage.

[0020] In addition, two sets of water tanks 10 and two sets of hollow pipes 14 are respectively installed on both sides of the drone body 1. A pump body 11 connected to the water tanks 10 and hollow pipes 14 is installed at the bottom. Multiple sprayers 16 are installed on the outside of the hollow pipes 14. A three-way pipe 12 is fixed to the output end of the pump body 11. The two ends of the three-way pipe 12 are connected to the corresponding hollow pipes 14 through water guide pipes 13. Under the action of the pump body, the water in the water tank is transported to the hollow pipe through the three-way pipe and the water guide pipe, and then distributed to each sprayer through the water delivery pipe. The sprayers evenly spray the water to the sowing area, realizing simultaneous sowing and watering.

[0021] Meanwhile, multiple sprayers 16 are locked and fixed to the outside of the hollow tube 14 by the guide frame 15. The sprayers 16 and the hollow tube 14 are connected by a water supply pipe 17 passing through the guide frame 15 to ensure that the water flow is stably delivered to each sprayer. The UAV body and the hollow tube are connected by a tie rod 18 to enhance the structural stability.

[0022] Working principle:

[0023] Seeds are poured in through the top hopper. A stirring rod inside the hopper, driven by a motor, rotates to agitate the seeds, preventing clumping and blockage at the connection between the hopper and the seed box. This ensures smooth seed flow into the seed box. Inside the seed box, seed-distributing blocks are driven to rotate by an outer motor. As the blocks rotate, their outer seed troughs extend sequentially through the hopper sidewall to a baffle inside the seed box. When a seed trough passes the baffle, it blocks excess seeds above it, allowing only seeds within the trough to pass through, achieving quantitative seed distribution. When the seed-distributing blocks reach the bottom of the seed box, the seeds in the troughs fall through the seed-dropping tube. Combined with the drone's flight speed, the seeds slide evenly down the slope. To avoid concentrated accumulation and achieve uniform sowing, water tanks on both sides of the drone store water. After the pump at the bottom is activated, the water in the tanks is drawn out and distributed to the water guide pipes on both sides through a three-way pipe, and then delivered to the hollow pipe. Multiple sprayers are fixed to the outside of the hollow pipe through a guide frame. The water inside the hollow pipe flows into the sprayers through the water delivery pipe, and the sprayers spray the water evenly to the sowing area. The tie rod connects the drone body to the hollow pipe, enhancing the structural stability of the watering components and preventing shaking during flight from affecting the spraying accuracy. Multiple sets of sprayers are evenly distributed to ensure comprehensive coverage of the watering area and uniform water volume, which is completed simultaneously with sowing, reducing the time loss of traditional step-by-step operations.
