Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a tray loading mechanism for UAV seeding. Background Technology

[0002] Agricultural drones mainly consist of several major components, including a flight system, control system, power system, spraying system, and monitoring system. Their flight control principle is based on a multi-rotor layout, achieving actions such as ascent, descent, roll, pitch, and yaw by adjusting motor speeds. Agricultural drones can accurately complete tasks such as sowing and spraying while maintaining stable flight. When sowing and fertilizing, drones require a seeder, and the bottom of the seeder needs a tray-loading mechanism. This drone tray-loading mechanism uses a centrifugal disc to throw seeds or fertilizer out for sowing. However, existing drone tray-loading mechanisms have a fixed structure, making it difficult to adjust the sowing range during use, resulting in poor practicality. Utility Model Content

[0010] A fixed shell is fixedly connected to the bottom of the mounting plate, and the bottom of the fixed shell has multiple discharge holes;

[0011] The feeding tube is connected and fixed to the top of the outer wall of the fixed shell;

[0012] A circular shell is disposed at the top of the inner side of the fixed shell. Multiple connecting rods are fixedly connected between the outer side wall of the circular shell and the inner side wall of the fixed shell. A stepper motor is fixedly connected inside the circular shell. The output end of the stepper motor passes through the side wall of the circular shell and is fixedly connected to a rotating rod. The top of the rotating rod is rotatably connected to the bottom of the circular shell. The bottom of the rotating rod passes through the side wall of the fixed shell and extends to the outer side of the fixed shell.

[0013] Preferably, a helical blade is sleeved and fixed on the rotating rod, and the helical blade is in contact with the inner wall of the fixed shell.

[0014] Preferably, a rotating ring is sleeved and fixed to the bottom of the outer side wall of the rotating rod, and multiple stirring rods are uniformly fixed to the outer side wall of the rotating ring, and the multiple stirring rods are in contact with the inner bottom surface of the fixed shell.

[0015] Preferably, a baffle plate is fitted and fixed to the bottom of the outer side wall of the fixed shell.

[0016] Furthermore, the dissemination mechanism includes:

[0017] A rotating shell, the top of which is fixedly connected to the bottom of a rotating rod;

[0018] Multiple connecting shells are all fixedly connected to the outer side wall of the rotating shell;

[0019] Multiple fixing plates are fixed at one end to the outer wall of the rotating shell, and both sides of the multiple fixing plates are fixed to the corresponding connecting shells.

[0020] Preferably, one end of the connecting shell has a connecting notch, and multiple connecting shells have slidingly connected moving rods inside. An elastic rubber pad is provided between each pair of adjacent moving rods. One side of each elastic rubber pad is bonded to a corresponding fixing plate, and the elastic rubber pad is bonded to the ends of two corresponding moving rods. A rotating disk is rotatably connected to the bottom of the rotating shell, and the top of the rotating disk passes through the side wall of the rotating shell and extends into the interior of the rotating shell. A bevel gear is fixedly connected to the top of the rotating disk. A fixing block is fixedly connected to the inner top surface of the rotating shell. Multiple round rods are rotatably connected to the fixed block. A bevel gear is fixedly sleeved on each round rod, and all bevel gears mesh with the bevel gears. One end of each round rod is fixedly connected to a universal joint, and one end of the universal joint is fixedly connected to a round rod. One end of the round rod passes through the side wall of the rotating housing and is rotatably connected to the corresponding connecting housing.

Multiple fixing bolts are screwed onto the rotating disk, and one end of each fixing bolt is screwed into the corresponding threaded groove.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By setting a conveying mechanism on the mounting plate and using a feeding pipe to easily transport seeds or fertilizer into the interior of the fixed shell, and by starting the stepper motor, the spiral blades and the spreading mechanism rotate. The rotating spiral blades facilitate the uniform conveying of seeds or fertilizer, and multiple discharge holes allow seeds or fertilizer to fall onto the top of multiple connecting shells and multiple fixed plates. The rotating connecting shells and multiple fixed plates facilitate the throwing out of seeds or fertilizer. By controlling the speed of the stepper motor, the speed of the rotating rod and the spreading mechanism are adjusted, thereby adjusting the spreading range when the spreading mechanism rotates. This makes it more convenient to use and improves the practicality of the tray loading mechanism for drone seeding.

[0023] 2. Multiple stirring rods are evenly fixed to the outer wall of the rotating ring. The rotating rods drive the rotating ring and the multiple stirring rods to rotate. The multiple stirring rods stir the seeds or fertilizers at the bottom of the inner side of the fixed shell, which prevents the seeds or fertilizers from clumping together and avoids the clumping of seeds or fertilizers from blocking the discharge hole and affecting the feeding.

[0024] 3. By setting elastic rubber pads between adjacent moving rods in multiple moving rods, and by rotating the rotating disk, the multiple moving rods can be moved. After the moving rods move, their ends will pull the ends of the corresponding elastic rubber pads to move, thereby stretching or contracting the elastic rubber pads, and thus adjusting the overall area of ​​the seeding mechanism. By adjusting the overall area of ​​the seeding mechanism, it is easier to adjust the seeding range when the seeding mechanism is used, thus improving the applicability of the tray loading mechanism for drone seeding.

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.

[0032] Please see Figure 1-5 In this embodiment of the utility model, a tray loading mechanism for seeding by a drone includes: a mounting plate 100, a conveying mechanism 200, and a spreading mechanism 300. The conveying mechanism 200 is disposed on the mounting plate 100 and is used to convey seeds or fertilizers. The spreading mechanism 300 is disposed at the bottom of the conveying mechanism 200.

[0033] Specifically, the mounting plate 100 facilitates the installation of the seeding tray mechanism on the drone, and the conveying mechanism 200 facilitates the transport of seeds or fertilizers to the top of the spreading mechanism 300. The conveying mechanism 200 can drive the spreading mechanism 300 to rotate, thereby using the rotating spreading mechanism 300 to easily throw out the seeds or fertilizers to complete the sowing. Furthermore, the spreading mechanism 300 can adjust the sowing area, making it more convenient to use.

[0034] Example 1

[0035] like Figure 2-3As shown, in this embodiment, the conveying mechanism 200 includes a fixed shell 210, a feeding pipe 220, and a circular shell 230. The fixed shell 210 is fixedly connected to the bottom of the mounting plate 100. Multiple discharge holes 211 are provided at the bottom of the fixed shell 210. The feeding pipe 220 is connected and fixedly connected to the top of the outer wall of the fixed shell 210. The circular shell 230 is disposed at the top of the inner side of the fixed shell 210. Multiple connecting rods 231 are fixedly connected between the outer wall of the circular shell 230 and the inner wall of the fixed shell 210. A stepper motor 232 is fixedly connected inside the circular shell 230. The output end of the stepper motor 232 passes through the side wall of the circular shell 230 and is fixedly connected to a rotating rod 240. The top of the rotating rod 240 is rotatably connected to the bottom of the circular shell 230. The bottom of the rotating rod 240 passes through the side wall of the fixed shell 210 and extends to the outside of the fixed shell 210. A spiral blade 241 is sleeved and fixed on the rotating rod 240, and the spiral blade 241 contacts the inner side wall of the fixed shell 210. A baffle plate 260 is sleeved and fixed at the bottom of the outer side wall of the fixed shell 210. The spreading mechanism 300 includes a rotating shell 310, multiple connecting shells 320 and multiple fixing plates 330. The top of the rotating shell 310 is fixedly connected to the bottom of the rotating rod 240. The multiple connecting shells 320 are all fixedly connected to the outer side wall of the rotating shell 310. One end of the multiple fixing plates 330 is fixedly connected to the outer side wall of the rotating shell 310, and the two sides of the multiple fixing plates 330 are respectively fixedly connected to the corresponding connecting shells 320.

[0036] In this embodiment, by connecting the feeding pipe 220 to the seed or fertilizer storage box of the drone, the feeding pipe 220 facilitates the delivery of seeds or fertilizer into the interior of the fixed shell 210, allowing the seeds or fertilizer to fall onto the top of the spiral blades 241. By activating the stepper motor 232, the rotating rod 240 and the spiral blades 241 rotate, allowing the spiral blades 241 to deliver the seeds or fertilizer at a uniform speed, thus conveying them to the bottom of the inner side of the fixed shell 210. Multiple discharge holes 211 further facilitate the delivery of the seeds or fertilizer. Seeds or fertilizers fall onto the top of multiple connecting shells 320 and multiple fixing plates 330. The rotating rod 240 rotates, causing the rotating shell 310, multiple connecting shells 320 and multiple fixing plates 330 to rotate. The rotating connecting shells 320 and multiple fixing plates 330 facilitate the throwing out of the seeds or fertilizers. By controlling the speed of the stepper motor 232, the speed of the rotating rod 240 and the spreading mechanism 300 are adjusted, thereby adjusting the feeding speed of the spiral blades 241 and the spreading range when the spreading mechanism 300 rotates, making it more convenient to use.

[0037] like Figure 2 As shown, in this embodiment, a rotating ring 250 is fixedly sleeved on the bottom of the outer side wall of the rotating rod 240. A plurality of stirring rods 251 are uniformly fixed on the outer side wall of the rotating ring 250, and the plurality of stirring rods 251 are in contact with the inner bottom surface of the fixed shell 210.

[0038] In practice, the rotating rod 240 drives the rotating ring 250 and multiple stirring rods 251 to rotate. The multiple stirring rods 251 are used to stir the seeds or fertilizer at the bottom of the inner side of the fixed shell 210, so as to avoid the seeds or fertilizer from clumping and sticking together, and to prevent the clumped seeds or fertilizer from blocking the discharge hole 211 and affecting the feeding.

[0039] Example 2

[0040] Based on Example 1, in order to adjust the spreading range when the spreading mechanism 300 is in use.

[0041] like Figure 4-5 As shown, in this embodiment, a connection notch 321 is provided at one end of the connecting shell 320. Movable rods 340 are slidably connected inside the multiple connecting shells 320. An elastic rubber pad 341 is provided between adjacent moving rods 340. One side of the elastic rubber pad 341 is bonded and fixed to the corresponding fixing plate 330, and the elastic rubber pad 341 is bonded and fixed to the ends of the corresponding two moving rods 340. A rotating disk 350 is rotatably connected to the bottom of the rotating shell 310, and the top of the rotating disk 350 passes through the side wall of the rotating shell 310 and extends into the interior of the rotating shell 310. A bevel gear 351 is fixedly connected to the top of the rotating disk 350, and a fixing block 360 is fixedly connected to the inner top surface of the rotating shell 310. Multiple round rods 361 are rotatably connected to the fixed block 360. A bevel gear 362 is sleeved and fixed on the round rod 361, and all the bevel gears 362 mesh with the bevel gear 351. One end of the round rod 361 is fixedly connected to a universal joint 363, and one end of the universal joint 363 is fixedly connected to a round rod 364. One end of the round rod 364 passes through the side wall of the rotating shell 310 and is rotatably connected to the corresponding connecting shell 320. One end of the round rod 364 is fixedly connected to a screw 365, and the screw 365 is screwed into the corresponding moving rod 340. Multiple threaded grooves are opened at the bottom of the rotating shell 310. Multiple fixing bolts 370 are screwed into the rotating disk 350, and one end of the fixing bolt 370 is screwed into the corresponding threaded groove.

[0042] In specific implementation, rotating the rotating disk 350 causes the bevel gear 351 to rotate, which meshes with multiple bevel gears 362, thereby causing the multiple bevel gears 362 and multiple round rods 361 to rotate. The rotating round rods 361 use universal joints 363 to rotate round rods 364 and screws 365. The screws 365 are screwed into the corresponding moving rods 340 and slidably connected to the corresponding connecting shells 320, thereby causing the multiple moving rods 340 to move. After the moving rods 340 move, their ends pull the ends of the corresponding elastic rubber pads 341 to move, thereby affecting the elastic rubber pads 341. 41. By stretching or contracting, the overall area of ​​the spreading mechanism 300 is adjusted. Adjusting the overall area of ​​the spreading mechanism 300 facilitates the adjustment of the spreading range during use, making it more convenient to use. After adjustment, by screwing the fixing bolts 370 into the corresponding threaded grooves, the positions of the bevel gear 351, multiple bevel gears 362, multiple round rods 361, multiple universal joints 363, multiple round rods 364, multiple screws 365, and multiple moving rods 340 are fixed, which in turn facilitates the fixing of the positions of multiple elastic rubber pads 341, ensuring the stability of the spreading mechanism 300 during use.
