Description

Technical Field

[0001] This utility model relates to the field of agricultural sowing technology, and in particular to a sowing device for agricultural drones. Background Technology

[0002] Agricultural drone seeding devices are one of the core equipment for agricultural modernization. By integrating high-precision positioning, intelligent seeding systems and efficient power platforms, they have achieved precision, automation and large-scale seeding operations, and promoted agricultural production toward the goal of zero waste, zero labor and zero risk.

[0003] In existing technologies, this device uses centrifugal and pneumatic seeding mechanisms, and the integration of lidar, millimeter-wave radar, and a five-eye vision system has become standard. It can cover a wide area in a single takeoff and landing, with high seeding uniformity. It can identify obstacles such as power lines and trees, supports survey-free terrain-following flight, and has strong adaptability to complex terrain. However, in hilly and orchard scenarios, drones are prone to signal interruption due to terrain obstruction, and the seeding rate fluctuates due to unstable flight altitude. Now, by using DJI T100 equipped with lidar and a five-eye vision system, survey-free terrain-following flight can be achieved. Through AI training datasets, the features of field ridges and ditches are automatically marked, improving the operation coverage. However, the drone body vibrates during flight, and the vibration is directly transmitted to the hopper and seed metering device, causing the hopper feeding and seed metering mechanisms to jam or even loosen. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a seeding device for agricultural drones, which aims to improve the problem in the prior art where the drone body vibrates during flight and the vibration is directly transmitted to the hopper and seed metering device, causing the hopper feeding and seed metering mechanism to jam or even loosen.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seeding device for an agricultural drone, comprising a fuselage, a hopper installed in the middle of the bottom wall of the fuselage, and mounting mechanisms installed on the front and rear sides of the bottom wall of the fuselage, the mounting mechanisms being used to fix the hopper, a fixing mechanism being installed at the bottom of the hopper, the fixing mechanism being used to facilitate the installation and disassembly of components; the mounting mechanism comprising a fixing plate, the fixing plate being fixedly connected to the front and rear sides of the bottom wall of the fuselage, a slider being fixedly connected to one end of the fixing plate, a fixing frame being slidably connected to the outer wall of the slider, the fixing frame being connected to the hopper, a locking block being fixedly connected to one side of the outer wall of the fixing frame, a limiting plate being fixedly connected to the middle of the bottom wall of the fixing plate, a pull rod being slidably connected to the inner wall of the limiting plate, and a long plate being fixedly connected to the end of the pull rod.

[0006] As a further description of the above technical solution: Multiple sliding rods are fixedly connected at equal intervals on the front side of the outer wall of the long plate. The sliding rods are slidably connected to the inner wall of the limiting plate. Springs are installed on the outer wall of the sliding rods. A protrusion is fixedly connected to the rear side of the outer wall of the long plate. The protrusion is slidably connected to the inner wall of the locking block. A locking assembly is installed at the bottom of the locking block.

[0007] As a further description of the above technical solution: The engaging assembly includes a plug rod that is slidably connected to the inner wall of the locking block and the protrusion. A bolt is threadedly connected to the inner wall of the plug rod, and the bolt is threadedly connected to the inner wall of the protrusion.

[0008] As a further description of the above technical solution: The fixing mechanism includes a mounting block, which is fixedly connected to the front side of the bottom wall of the silo. A seed metering device is installed at the bottom of the silo. Limiting grooves are opened on both the left and right sides of the outer wall of the seed metering device. A support arm is fixedly connected to the left side of the outer wall of the mounting block.

[0009] As a further description of the above technical solution: Both the outer walls of the first support arm and the second support arm are fixedly connected to limit blocks, and the limit blocks are slidably connected to the inner wall of the limit groove.

[0010] As a further description of the above technical solution: Both the outer walls of the first support arm and the second support arm are fixedly connected to limit blocks, and the limit blocks are slidably connected to the inner wall of the limit groove.

[0011] As a further description of the above technical solution: A battery is installed on the rear side of the outer wall of the device, and a camera is installed on the front side of the outer wall of the device.

[0012] As a further description of the above technical solution: The outer wall of the fuselage is fixedly connected with multiple fixed rods at equal intervals, and a propeller is installed at the end of each fixed rod.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when installing the hopper, first pull the two pull rods outward simultaneously. The pull rods drive the long plate and the protrusions on its outer wall to slide outward within the limiting plate. The sliding rod on the right side of the outer wall of the long plate will also slide within the limiting plate. While the sliding rod slides, it will compress the spring. After pulling out the pull rods, slide the fixing frames on both sides of the hopper upward along the outer wall of the slider. Then release the pull rods. The spring will quickly rebound and push the long plate, so that the protrusions on the outer wall of the long plate are inserted into the clips on the outer wall of the fixing frame. Finally, insert the insertion rod into the inner wall of the clips and the protrusions, and screw in the bolts. The bolts fix the insertion rod and the protrusions together to form a stable connection, fixing the hopper to the bottom wall of the machine body. This forms a stable connection and prevents the body from vibrating during the flight of the drone and the vibration from being directly transmitted to the hopper and the seed metering device, which could cause the hopper feeding and seed metering mechanisms to jam or even loosen.

[0014] 2. In this utility model, when replacing the seed metering device, the motor on the mounting block needs to be started. The motor rotates and drives the first support arm to rotate and open, so that the limiting block on the first support arm slides out of the limiting groove on the right side of the seed metering device. Then, hold the seed metering device by hand and move it to the right to remove the seed metering device from the limiting block on the second support arm. Slide the new seed metering device along the limiting block on the second support arm, start the motor to make the motor rotate in the opposite direction, and the motor drives the first support arm to rotate back. The limiting block on the first support arm will be locked into the limiting groove on the right side of the seed metering device. The operation is convenient, and it is easy to install and disassemble the seed metering device, thus improving maintenance efficiency. Attached Figure Description

[0017] 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.

[0018] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a seeding device for an agricultural drone, comprising a fuselage 1. The fuselage 1 is made of a one-piece molded carbon fiber composite shell. The outer wall of the shell is sanded to improve anti-slip and scratch resistance, and the inner wall has multiple reinforcing ribs (to enhance the torsional strength of the fuselage 1 and prevent deformation during flight). A hopper 2 is installed in the middle of the bottom wall of the fuselage 1. The hopper 2 stores seeds, prevents blockage, and assists in monitoring the remaining seed level. Mounting mechanisms 3 are installed on the front and rear sides of the bottom wall of the fuselage 1. The mounting mechanisms 3 are used to fix the hopper 2. A fixing mechanism 4 is installed at the bottom of the hopper 2 to facilitate the installation and disassembly of components. The mounting mechanism 3 includes a fixing plate 302, which is fixedly connected to the front and rear sides of the bottom wall of the fuselage 1. A slider 301 is fixedly connected to one end of the fixing plate 302. A fixing frame 310 is slidably connected to the outer wall of the slider 301. The fixing frame 310 and the hopper 301 are connected to the slider 301. The two compartments are connected. A locking block 309 is fixedly connected to one side of the outer wall of the fixed frame 310. A limiting plate 303 is fixedly connected to the middle of the bottom wall of the fixed plate 302. A pull rod 304 is slidably connected to the inner wall of the limiting plate 303. A long plate 307 is fixedly connected to the end of the pull rod 304. Multiple sliding rods 306 are fixedly connected at equal intervals to the front side of the outer wall of the long plate 307. The sliding rods 306 are slidably connected to the inner wall of the limiting plate 303. Springs are installed on the outer wall of the sliding rods 306. A protrusion 308 is fixedly connected to the rear side of the outer wall of the spring 305 and the long plate 307. The protrusion 308 is slidably connected to the inner wall of the locking block 309. A locking assembly 311 is installed at the bottom of the locking block 309. The locking assembly 311 includes a plug rod 3112. The plug rod 3112 is slidably connected to the inner wall of the locking block 309 and the protrusion 308. A bolt 3111 is threadedly connected to the inner wall of the plug rod 3112. The bolt 3111 is threadedly connected to the inner wall of the protrusion 308. Specifically, when installing the hopper 2, first pull both levers 304 outward simultaneously. The levers 304 drive the long plate 307 and the protrusions 308 on its outer wall to slide outward within the limiting plate 303. The sliding rod 306 on the right side of the outer wall of the long plate 307 will also slide within the limiting plate 303. As the sliding rod 306 slides, it will compress the spring 305. After pulling out the levers 304, slide the fixing frames 310 on both sides of the hopper 2 upward along the outer wall of the slider 301. Then release the levers 304, and the spring 305 will quickly rebound and push the long plate 307. The protrusion 308 on the outer wall of the long plate 307 is inserted into the locking block 309 on the outer wall of the fixed frame 310. Finally, the insertion rod 3112 is inserted into the inner wall of the locking block 309 and the protrusion 308, and the bolt 3111 is screwed in. The bolt 3111 fixes the insertion rod 3112 and the protrusion 308 together to form a stable connection, thus fixing the hopper 2 to the bottom wall of the body 1 to form a stable connection. This prevents the body 1 from vibrating during the flight of the drone and prevents the vibration from being directly transmitted to the hopper 2 and the seed metering device 401, which could cause the feeding and seed metering mechanism of the hopper 2 to jam or even loosen.

[0019] Reference Figure 1 , Figure 2 and Figure 5 The fixing mechanism 4 includes a mounting block 404, which is fixedly connected to the front side of the bottom wall of the hopper 2. A seed metering device 401 is installed at the bottom of the hopper 2. The seed metering device 401 is a Dongfeng Iseki 2BQFX-8 pneumatic precision seed metering device 401. The seed metering device 401 guides the seeds to the ground to avoid seed damage and displacement. Limiting grooves 407 are opened on the left and right sides of the outer wall of the seed metering device 401. A second support arm 406 is fixedly connected to the left side of the outer wall of the mounting block 404. A motor 405 is fixedly connected to the right side of the bottom wall of the mounting block 404. The motor 405 is a T-Motor A12KV50. A first support arm 403 is fixedly connected to the output end of the motor 405. Limiting blocks 402 are fixedly connected to the outer walls of both the first support arm 403 and the second support arm 406. The limiting blocks 402 are slidably connected to the inner wall of the limiting grooves 407. Specifically, when replacing the seed metering device 401, the motor 405 on the mounting block 404 needs to be started. The rotation of the motor 405 drives the first support arm 403 to rotate and open, causing the limiting block 402 on the first support arm 403 to slide out of the limiting groove 407 on the right side of the seed metering device 401. Then, hold the seed metering device 401 by hand and move it to the right to remove the seed metering device 401 from the limiting block 402 on the second support arm 406. Slide the new seed metering device 401 along the limiting block 402 on the second support arm 406. Start the motor 405 to rotate in the opposite direction. The motor 405 drives the first support arm 403 to rotate back, and the limiting block 402 on the first support arm 403 will be locked into the limiting groove 407 on the right side of the seed metering device 401. The operation is convenient, making it easy to install and remove the seed metering device 401 and improving maintenance efficiency.

[0020] Reference Figure 1 , Figure 2 and Figure 3 A battery 7 is installed on the rear side of the outer wall of the body 1. The battery 7 is a DJIT70DB1580-Li-ion. A camera 8 is installed on the front side of the outer wall of the body 1. The camera 8 is a DJI Phantom 4 Multispectral Edition. Multiple fixing rods 5 are fixedly connected at equal intervals on the outer wall of the body 1. A propeller 6 is installed at the end of the fixing rod 5. Specifically, battery 7 serves as the power source for the drone, and its core function is to provide stable power to all electrical components of the drone. It directly powers the propeller 6 at the end of the fixed rod 5, driving the propeller 6 to rotate and generate lift. Camera 8 collects high-definition images and videos of the front and surrounding environment in real time, and transmits them back to the ground station through the image transmission module, allowing operators to observe the flight environment (such as avoiding obstacles and confirming the work area). The propeller 6 is installed at the end of the fixed rod 5, and its rigid structure bears the reaction force when the propeller 6 rotates. As the core of power conversion, the propeller 6 converts rotational kinetic energy into the lift and thrust required for the drone's flight.

[0021] Working principle: When installing the hopper 2, first pull the two levers 304 outward simultaneously. The levers 304 drive the long plate 307 and the protrusions 308 on its outer wall to slide outward within the limiting plate 303. The sliding rod 306 on the right side of the outer wall of the long plate 307 will also slide within the limiting plate 303. As the sliding rod 306 slides, it will compress the spring 305. After pulling out the levers 304, slide the fixing frames 310 on both sides of the hopper 2 upward along the outer wall of the slider 301. Then release the levers 304, and the spring 305 will quickly rebound and push the long plate 307. The protrusion 308 on the outer wall of the long plate 307 is inserted into the locking block 309 on the outer wall of the fixed frame 310. Finally, the insertion rod 3112 is inserted into the inner wall of the locking block 309 and the protrusion 308, and the bolt 3111 is screwed in. The bolt 3111 fixes the insertion rod 3112 and the protrusion 308 together to form a stable connection. This fixes the hopper 2 to the bottom wall of the body 1 to form a stable connection, preventing the body 1 from vibrating during the flight of the drone and preventing the vibration from being directly transmitted to the hopper 2 and the seed metering device 401, which could cause the feeding and seed metering mechanism of the hopper 2 to jam or even loosen. When replacing the seed metering device 401, the motor 405 on the mounting block 404 needs to be started. The rotation of the motor 405 drives the support arm 1 403 to rotate and open, so that the limiting block 402 on the support arm 1 403 slides out of the limiting groove 407 on the right side of the seed metering device 401. Then, hold the seed metering device 401 by hand and move it to the right to remove the seed metering device 401 from the limiting block 402 on the support arm 2 406. Slide the new seed metering device 401 along the limiting block 402 on the support arm 2 406. Start the motor 405 to make the motor 405 rotate in the opposite direction. The motor 405 drives the support arm 1 403 to rotate back, and the limiting block 402 on the support arm 1 403 will be locked into the limiting groove 407 on the right side of the seed metering device 401. The operation is convenient, and it is easy to install and remove the seed metering device 401, which improves maintenance efficiency.
