Description

Technical Field

[0001] This utility model relates to the field of rapeseed sowing technology, specifically a rapeseed aerial seeding device. Background Technology

[0002] Rapeseed aerial seeding is a specialized aerial seeding equipment for rapeseed. Aerial seeding is a method of sowing seeds in the air, usually using aircraft such as drones, airplanes, or helicopters to evenly scatter the seeds into the field.

[0003] For example, Chinese Patent CN114532007A discloses a rapeseed aerial seeding device, including a flight mechanism. An L-shaped plate is longitudinally fixed at the lower end of the flight mechanism. A rapeseed container is fixed between two L-shaped plates via a fixing mechanism. A feeding hopper is fixed to the lower side wall of the rapeseed container. A feeding pipe is fixed to the lower side wall of the feeding hopper. A feeding rate adjustment mechanism is installed inside the feeding pipe. Symmetrical seeding pipes are fixed to the side wall of the feeding pipe. Symmetrical rotating pipes are sleeved at the lower ends of both seeding pipes. Annular grooves are formed in the walls of both seeding pipes. Symmetrical limiting blocks are fixed to the inner walls of both rotating pipes. This allows for adjustment of the feeding rate according to soil conditions and the sowing season, thereby controlling the density of rapeseed sowing and facilitating later rapeseed growth.

[0004] During the rapeseed aerial seeding process, drones need to fly to a certain altitude to ensure safe flight. However, because rapeseed seeds are small, they are easily affected by wind, causing the seeds to scatter and making it difficult for them to land accurately at the intended location. Utility Model Content

[0005] The purpose of this utility model is to provide a special aerial seeding device for rapeseed, in order to solve the problem in the above-mentioned background technology that during the aerial seeding of rapeseed, the drone needs to fly to a certain altitude to ensure safe flight. However, because rapeseed seeds are small and easily affected by wind, the seeds are scattered and difficult to land accurately at the predetermined position.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapeseed-specific aerial seeding device, comprising a drone body, a feeding structure installed at the bottom of the drone body, and an extension structure installed at the bottom of the feeding structure;

[0007] The extension structure includes a first feeding pipe and a second feeding pipe installed at the bottom of the feeding structure of the UAV body. The first feeding pipe and the second feeding pipe are distributed in parallel. A corrugated pipe is fixedly connected between the first feeding pipe and the second feeding pipe. The end of the first feeding pipe away from the corrugated pipe is connected to the feeding structure. Both ends of the first feeding pipe are fixedly connected with symmetrically distributed extension rods.

[0008] Preferably, the extension rods at both ends of the first conveying pipe are respectively fixedly connected to a first worm gear and a second worm gear, and the extension rod of the second conveying pipe near the end of the first conveying pipe is fixedly connected to a third worm gear, so that the first conveying pipe and the second conveying pipe form a folding and telescopic structure.

[0009] Preferably, the extension rods at the close ends of the first and second feed pipes are hinged together by a connecting rod, and a second worm gear driven by a motor is rotatably connected in the middle of the connecting rod. The outer side of the second worm gear meshes with the outer side of the second and third worm wheels respectively. A first worm gear driven by a motor is installed at the bottom of the UAV body, and the first worm gear meshes with the outer side of the first worm wheel.

[0010] Preferably, the end of the second conveying pipe away from the first conveying pipe is fixedly connected to a discharge pipe via a corrugated pipe. The outer side of the discharge pipe is fixedly connected to symmetrically distributed extension rods. The extension rods on the outer side of the discharge pipe and the extension rods at the end of the second conveying pipe are hinged to each other. Counterweights are fixedly connected to both sides of the bottom of the discharge pipe. The discharge pipe is always perpendicular to the ground.

[0011] Preferably, the feeding structure includes a loading tank that is detachably installed inside the insertion slot. The loading tank has a discharge port at the bottom and a feeding port at the top. The top of the loading tank is hinged with a lid that completely covers the feeding port.

[0012] Preferably, a limiting block is slidably connected inside the end of the can lid away from the hinged end with the filling tank, and the limiting block is engaged with the inside of the filling tank to form a locking structure.

[0013] Preferably, the feeding structure further includes a feeding pipe fixedly connected to the bottom of the UAV body, the input end and the output end of the feeding pipe being aligned with each other, the output end of the feeding pipe being connected to the first conveying pipe through a corrugated pipe, a transport screw being rotatably connected inside the feeding pipe, and a conveying motor being threadedly connected to the end of the feeding pipe, the output end of the conveying motor being fixedly connected to the transport screw.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This is a rapeseed-specific aerial seeding device. By deploying the second feeding pipe relative to the first feeding pipe, the drone body can reduce the distance between the seeds and the soil from the feeding pipe without lowering its flight altitude. This prevents the seeds from being blown away by the wind when descending from high altitude, and the vertical discharge reduces seed drift and improves the sowing accuracy.

[0016] The sealing is ensured by a limit block as a locking element. When the can lid is closed, the user pushes the limit block in, which locks it into the filling can, forming a mechanical lock to prevent the can lid from accidentally popping open when the drone vibrates or flies at high speed. The bottom of the filling can has a discharge port that is aligned with the input end of the feeding pipe. The detachable and sealed design simplifies the maintenance process and makes it easy to clean or reinstall the filling can. Attached Figure Description

[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 4This utility model provides the following technical solution: a rapeseed-specific aerial seeding device, including a drone body 1, a feeding structure installed at the bottom of the drone body 1, and an extension structure installed at the bottom of the feeding structure; the extension structure includes a first feeding pipe 4 and a second feeding pipe 5 installed at the bottom of the feeding structure of the drone body 1, the first feeding pipe 4 and the second feeding pipe 5 are parallel to each other, a corrugated pipe 6 is fixedly connected between the first feeding pipe 4 and the second feeding pipe 5, the end of the first feeding pipe 4 away from the feeding structure is connected to the feeding structure through the corrugated pipe 6, and symmetrically distributed extension rods 7 are fixedly connected to both ends of the first feeding pipe 4; Figure 2 As shown, the extension rods 7 at both ends of the first conveying pipe 4 are respectively fixedly connected to a first worm gear 8 and a second worm gear 9, and the extension rod 7 of the second conveying pipe 5 near the end of the first conveying pipe 4 is fixedly connected to a third worm gear 10. The first conveying pipe 4 and the second conveying pipe 5 form a folding and telescopic structure; Figure 3 As shown, the extension rods 7 at the near ends of the first feed pipe 4 and the second feed pipe 5 are hinged together by a connecting rod. A second worm gear 12 driven by a motor is rotatably connected in the middle of the connecting rod. The outer sides of the second worm gear 12 mesh with the outer sides of the second worm wheel 9 and the third worm wheel 10, respectively. A first worm gear 11 driven by a motor is installed at the bottom of the UAV body 1, and the first worm gear 11 meshes with the outer side of the first worm wheel 8. Figure 4 As shown, the end of the second conveying pipe 5 away from the first conveying pipe 4 is fixedly connected to the discharge pipe 13 via a corrugated pipe 6. The outer side of the discharge pipe 13 is fixedly connected to symmetrically distributed extension rods 7. The extension rods 7 on the outer side of the discharge pipe 13 and the extension rods 7 at the end of the second conveying pipe 5 are hinged to each other. The bottom sides of the discharge pipe 13 are fixedly connected to counterweights 14. The discharge pipe 13 is always perpendicular to the ground.

[0026] The first conveying pipe 4 and the second conveying pipe 5 are parallel to each other and are fixedly connected by a corrugated pipe 6. The corrugated pipe 6 acts as a flexible element, allowing the first conveying pipe 4 and the second conveying pipe 5 to bend and extend within a certain range. Each of the first conveying pipe 4 and the second conveying pipe 5 is fixedly connected to an extension rod 7. The extension rods 7 are symmetrically distributed at both ends of the pipe and are hinged together by a connecting rod to form a stable frame. In the working state, the control start motor of the UAV body drives the first worm gear 11. The first worm gear 11 is installed at the bottom of the UAV body 1, and its output end meshes with the outer side of the first worm wheel 8 at the end of the first conveying pipe 4. When the first worm gear 11 rotates, it drives the first worm wheel 8 to rotate, thereby adjusting the angle of the entire first conveying pipe 4 around the hinge point. At the same time, the connecting rod... The second worm gear 12, which is rotatably connected, is driven by another motor. The outer side of the second worm gear 12 meshes with the second worm wheel 9 and the third worm wheel 10 respectively. The second worm wheel 9 is fixed to the end extension rod 7 of the first conveying pipe 4, while the third worm wheel 10 is fixed to the extension rod 7 near the end of the second conveying pipe 5. Therefore, the rotation of the second worm gear 12 transmits torque through the worm wheel, causing the second conveying pipe 5 to fold or unfold relative to the first conveying pipe 4. The first worm gear 11 controls the base position of the first conveying pipe 4, while the second worm gear 12 drives the telescopic movement of the second conveying pipe 5. The corrugated pipe 6 is compressed or extended accordingly to adapt to the angle change. Before the drone takes off, the pipe can shrink to a small volume to reduce wind resistance and storage space; during seeding, it extends to the required length to expand the seeding range.

[0027] The discharge pipe 13 is fixedly connected to the far end of the second conveying pipe 5 via a corrugated pipe 6, and symmetrically distributed extension rods 7 are fixedly connected to its outer side. The extension rods 7 are hinged to the extension rods 7 at the end of the second conveying pipe 5 to form a movable joint. Counterweights 14 are fixedly connected to both sides of the bottom of the discharge pipe 13. The weight distribution ensures that the discharge pipe 13 remains perpendicular to the ground in a free state.

[0028] When the extension structure is unfolded and its position is adjusted, the discharge pipe 13 automatically aligns with the direction of gravity through the free rotation of the hinge point. During the sowing process, the seeds enter the first conveying pipe 4 from the feeding structure, and then flow into the discharge pipe 13 through the second conveying pipe 5. Furthermore, the unfolding of the second conveying pipe 5 relative to the first conveying pipe 4 allows the UAV body 1 to reduce the distance between the seeds and the soil from the discharge pipe 13 without lowering its flight altitude, preventing the seeds from being blown away by the wind when descending from high altitude. Vertical discharge reduces seed drift and improves sowing accuracy.

[0029] Example 2: Based on Example 1, please refer to... Figure 1 and Figure 2 as well as Figure 5 and Figure 6The following structure is also disclosed: the feeding structure includes a feeding tank 15 detachably installed inside the insertion slot 2, the bottom of the feeding tank 15 is provided with a discharge port 16, the top of the feeding tank 15 is provided with a feeding port, and the top of the feeding tank 15 is hinged with a tank cover 17 that completely covers the feeding port; Figure 5 and Figure 6 As shown, a limiting block 18 is slidably connected inside the end of the can lid 17 away from the hinged end with the filling tank 15. The limiting block 18 is engaged with the inner side of the filling tank 15 to form a locking structure; Figure 1 and Figure 2 As shown, the feeding structure also includes a feeding pipe 3 fixedly connected to the bottom of the UAV body 1. The input end of the feeding pipe 3 and the output port 16 are aligned with each other. The output end of the feeding pipe 3 is connected to the first conveying pipe 4 through the corrugated pipe 6. A transport screw 19 is rotatably connected inside the feeding pipe 3. A conveying motor 20 is threadedly connected to the end of the feeding pipe 3. The output end of the conveying motor 20 is fixedly connected to the transport screw 19.

[0030] The loading tank 15 is installed at the bottom of the drone body 1 via the insertion slot 2. The insertion slot 2 forms an alignment interface, allowing users to quickly insert and remove the loading tank 15. The top of the loading tank 15 has a feeding port for filling rapeseed seeds. The lid 17 is hinged to the top of the loading tank 15 via a hinge, forming an openable and closable sealed lid. During operation, the operator opens the lid 17 to fill the seeds through the feeding port and then closes the lid. The inside of the lid 17 is slidably connected to a limit block 18, which acts as a locking element to ensure a seal. When the lid 17 is closed, the user pushes the limit block 18 in, causing it to engage with the loading tank 15, forming a mechanical lock to prevent the lid 17 from accidentally popping open when the drone vibrates or flies at high speed. The bottom of the loading tank 15 has a discharge port 16, which is aligned with the input end of the feed pipe 3. The detachable and sealed design simplifies the maintenance process. After the sowing task is completed, the loading tank 15 is removed for cleaning or reloading.

[0031] The feeding pipe 3 is fixedly connected to the bottom of the UAV body 1. Its input end is aligned with the discharge port 16 to receive seeds, and its output end is connected to the first conveying pipe 4 through the corrugated pipe 6. The key component, the transport screw 19, is rotatably connected inside the feeding pipe 3 and is driven by the conveying motor 20. The conveying motor 20 is fixed to the end of the feeding pipe 3 through a threaded connection, and its output end is fixed to the transport screw 19. After the conveying motor 20 is started, it drives the transport screw 19 to rotate. The screw blades push the seeds forward along the pipe. The seeds enter the feeding pipe 3 from the discharge port 16, are conveyed by the screw, flow into the corrugated pipe 6, transition to the first conveying pipe 4, and finally flow into the extension structure to achieve sowing.
