Description

Technical Field

[0001] This invention relates to the field of agricultural seeders, specifically to an intelligent agricultural seeder. Background Technology

[0002] The core feature of intelligent agricultural seeders is that they achieve precise sowing through sensors, control systems and algorithms. Existing tray seeding seeders are a type of intelligent agricultural seeder. They use multiple vacuum adsorption heads to simultaneously adsorb multiple seeds, and then place the adsorbed seeds into trays on a conveyor belt through transparent tubes.

[0003] However, in existing seed tray agricultural seeders, when seeds fall through a transparent tube onto the seed tray containing substrate soil, the small size and light weight of the seeds (e.g., tomato seeds weigh only about 3mg) significantly affect air resistance during the fall, making them prone to deviating from their theoretical trajectory. Furthermore, the flat shape of seeds such as peppers and eggplants makes them prone to rotation during fall, increasing the probability of deviation. Additionally, the bottom of the transparent tube is at a certain height above the seed tray, so seeds often deviate from the center of the tray during the fall, leading to missed seeds. Therefore, we propose an intelligent agricultural seeder. Summary of the Invention

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Example 1

[0046] Please see Figures 1 to 3 A smart agricultural seeder includes a seeder body 1 for seedling tray cultivation and a conveyor platform 2 mounted on the seeder body 1. The conveyor platform 2 is equipped with a soil loading mechanism 21 and a hole pressing mechanism 22. The conveyor platform 2 is also equipped with a seed adsorption component 23, and multiple vacuum suction heads 24 are connected to the seed adsorption component 23. As a supplementary explanation, the soil loading mechanism 21 is an existing mechanism that uses a sensing method to evenly brush soil into the holes of the seed tray through a brush. Subsequently, the seed tray is moved to the hole pressing mechanism 22 by the conveyor belt on the conveyor platform 2. The hole pressing rod at the hole pressing mechanism 22 presses the seed tray to make it easier for the seeds to fall into the pressed holes.

[0047] A transparent tube 3 is provided on the lower side of one side of the vacuum suction head 24. The seeds are adsorbed one by one by the multiple vacuum suction heads 24 and the adsorbed seeds are placed into the transparent tube 3.

[0048] A guide tube 4 is slidably sleeved on the outer side of the bottom of the transparent tube 3, and multiple guide tubes 4 are fixedly connected to each other by a synchronization plate 41;

[0049] Please see Figures 4 to 11 The conveyor 2 is equipped with a push connector 5, which is used to push the synchronization plate 41. The push connector 5 includes a fixed plate 51, an electric push rod 52, and a push block 53. There are two fixed plates 51, which are fixedly installed on both sides of the conveyor 2. The electric push rod 52 is fixedly installed on the fixed plate 51, and the output end of the electric push rod 52 is fixedly connected to the push block 53. The two push blocks 53 are fixedly installed at both ends of the synchronization plate 41.

[0050] The two electric push rods 52 operate synchronously, which further enables the two push blocks 53 to drive the synchronous plate 41 to move vertically up and down relative to the conveyor table 2.

[0051] The bottom of the guide tube 4 is equipped with a closing adjustment component 6, and a support frame 7 is installed on the conveyor table 2. Multiple alignment and feeding components 8 are arranged at equal intervals on the support frame 7. The alignment and feeding components 8 and the closing adjustment component 6 cooperate with each other to ensure that the seeds fall accurately into the seed tray.

[0052] The closing adjustment component 6 includes a fixing block 61, a support rod 62, a support spring 63, a connecting plate 64, and a closing plate 65. The fixing block 61 is fixedly installed on the outside of the bottom of the guide tube 4. There are two support rods 62, and one end of each support rod 62 is fixedly connected to the fixing block 61. The connecting plate 64 is slidably sleeved on the outside of the two support rods 62. The support spring 63 is sleeved on the outside of the support rods 62. One end of the support spring 63 is fixedly connected to a support block 66, and the support block 66 is fixedly installed on the support rod 62. The other end of the support spring 63 is fixedly connected to the connecting plate 64.

[0053] One end of the closing plate 65 is fixedly connected to the connecting plate 64. The closing plate 65 is provided with a feeding hole 651. Both sides of the closing plate 65 are provided with a pushing port 652. The support frame 7 is provided with an adjusting inclined plate 71 at the position corresponding to the pushing port 652.

[0054] Specific implementation process: When the cavitation tray, after the cavitation is completed, moves towards the multiple guide tubes 4 along with the conveyor belt on the conveyor table 2, the vacuum suction head 24 on the transparent tube 3 sucks the seeds into the transparent tube 3. Then, the seeds fall into the bottom of the guide tube 4. At this time, the closing plate 65 closes the bottom of the guide tube 4. When a row of cavitation holes on the cavitation tray moves below the guide tube 4, the two electric push rods 52 operate simultaneously. The synchronization plate 41 causes the multiple guide tubes 4 to move vertically downward relative to the transparent tube 3. While the guide tubes 4 are moving downward, the closing plate 65 moves horizontally relative to the bottom of the guide tube 4 under the limiting action of the push port 652 and the adjusting inclined plate 71, and under the limiting action of the connecting plate 64, the support rod 62 and the support spring 63, until the discharge hole 651 of the closing plate 65 connects with the bottom of the guide tube 4. Then the seeds fall again from the guide tube 4.

[0055] This intermittent falling setting can reduce the seed's falling distance, prevent the seed from deviating during falling, and at the same time allow the seed to fall stably into the hole again.

[0056] As a supplementary explanation: the alignment unloading part 8 includes an alignment tube 81, a support ring 82 and a compression spring 83. The support frame 7 is provided with an alignment hole. The alignment tube 81 slides through the alignment hole. The support ring 82 is fixedly sleeved on the outside of the bottom of the alignment tube 81, and the compression spring 83 is sleeved on the outside of the alignment tube 81. The two ends of the compression spring 83 are fixedly connected to the support frame 7 and the support ring 82 respectively.

[0057] Specific implementation process: In this embodiment, under the support of the compression spring 83, when the seed plate moves along the direction of the alignment tube 81, the alignment tube 81 is located above the seed plate, thus not affecting the movement of the seed plate. At the same time, when the seed plate moves to the bottom of multiple alignment tubes 81, the multiple guide tubes 4 move vertically downward relative to the transparent tube 3. Meanwhile, the guide tubes 4 press down on the alignment tubes 81 through the closing plate 65 at their bottom, thereby causing the bottom of the alignment tubes 81 to move vertically downward relative to the seed hole. Thus, while the closing plate 65 moves relative to the bottom of the guide tube 4, the seed can always be guaranteed to fall into the seed hole through the alignment tube 81.

[0058] Please see Figures 7 to 11 The bottom of the guide pipe 4 is also provided with a pressurizing pipe 42, which is connected to the guide pipe 4. A pressurizing component 43 is provided at the pressurizing pipe 42. Multiple pushing blocks 53 are fixedly installed at equal intervals on the support frame 7. The pushing blocks 53 are used to push the pressurizing component 43.

[0059] The pressurizing component 43 includes a movable piston 431, a push rod 432, a push plate 433, a compression spring 434, a guide rod 435, and a clamping component 44. The movable piston is connected to the inside of the pressurizing tube 42. The push rod 432 slides through one end of the pressurizing tube 42, and both ends of the push rod 432 are fixedly connected to the movable piston 431 and the push plate 433, respectively. The compression spring 434 is sleeved on the outside of the push rod 432, and both ends of the compression spring 434 are fixedly connected to the pressurizing tube 42 and the push plate 433, respectively. The push plate 433 has a connecting slope on the side near the push block 53.

[0060] Two guide rods 435 are provided, and the two guide rods 435 are fixedly installed at the bottom of the guide tube 4. The push plate 433 is provided with two moving holes, and the push plate 433 is slidably sleeved on the outside of the guide rod 435 through the moving holes. The inside of the guide rod 435 away from the guide tube 4 is provided with a receiving cavity, and the clamping member 44 is provided at the receiving cavity. The support frame 7 is provided with a limiting plate 45 for connecting the two clamping members 44.

[0061] The clamping component 44 includes a clamping ball 441, a clamping rod 442, a contact block 443, and a spring sheet 444. The clamping rod 442 slides through the receiving cavity, and one end of the clamping rod 442 located inside the receiving cavity is fixedly connected to the clamping ball 441. The guide rod 435 is provided with a moving hole corresponding to the position of the clamping ball 441, and the push plate 433 is provided with a snap-fit ​​hole 4431 corresponding to the position of the clamping ball 441.

[0062] Spring sheet 444 is installed inside the movable cavity, and one end of spring sheet 444 is fixedly connected to clamping rod 442. The end of clamping rod 442 located outside the receiving cavity is fixedly connected to contact block 443, and the limiting plate 45 is provided with a pushing slope corresponding to the position of contact block 443.

[0063] Specific implementation process: When the feeding hole 651 of the closing plate 65 is connected to the bottom of the guide tube 4, that is, when the guide tube 4 moves down to the position where the locking part of the guide rod 435 contacts the pushing inclined surface, the two pushing inclined surfaces push the two contact blocks 443 simultaneously, thereby causing the locking rod 442 and locking ball 441 at the contact block 443 to deviate from the locking hole 4431 of the pushing plate 433. Then, under the reverse elastic force of the compression spring 434, the pushing plate 433 further causes the moving plug 431 to move along the inside of the pressurizing tube 42. While the moving plug 431 moves, it generates a downward airflow at the bottom of the guide tube 4, further causing the seeds to be stably blown into the hole.

[0064] Simultaneously, when the guide tube 4 moves upward, the push plate 433 moves relative to the two guide rods 435 under the limiting action of the push block 53 until the snap-fit ​​hole 4431 of the push plate 433 moves to the position of the snap-fit ​​bead 441. Then, due to the connection of the spring plate 444, the two snap-fit ​​beads 441 further clamp and position the push plate 433. This continues until the guide tube 4 moves downward again, causing the contact block 443 to move to the pushing slope of the limiting plate 45, thus causing the push plate 433 to disengage from the position of the snap-fit ​​bead 441.

[0065] Please see Figures 3 to 4 and Figures 12 to 16 The conveyor 2 is also equipped with an alignment and covering mechanism 9, which is connected to the push connector 5 to cover the corresponding holes in the seed trays into which the seeds are sown.

[0066] The soil covering mechanism 9 includes a guide shell 92, a bulldozer block 93, a tension rod 94, a rotating component 95, a soil guiding component 96, and a hopper 91. Multiple guide shells 92 are provided, and each guide shell 92 corresponds to a position of multiple transparent tubes 3.

[0067] The bulldozer block 93 is slidably connected inside the guide shell 92. The guide shell 92 has a moving port 921 on both sides. A connecting rod 97 slides through the moving port 921, and the two ends of the connecting rod 97 are fixedly connected to the adjacent bulldozer block 93.

[0068] Two tension rods 94 are provided, and the two tension rods 94 are fixedly installed at the bottom of the two push blocks 53 respectively. The bottom of the tension rod 94 is provided with a tension opening 941. The rotating part 95 is installed on the conveyor table 2 and is connected to the tension opening 941. One end of the rotating part 95 is connected to the nearby connecting rod 97.

[0069] The hopper 91 is fixedly installed on the conveyor table 2, and the soil guide 96 guides the soil in the hopper 91 to the bulldozer block 93.

[0070] The guide shell 92 has a feed inlet 921 at the top and a discharge port at the bottom of the other end. The bulldozer block 93 has a bulldozer hole 931. The bulldozer block guides the soil at the bulldozer hole 931 into the seedling tray through the discharge port. In addition, the bottom of the guide shell 92 can also be provided with a guide block. The guide block is used to guide and limit the seedling tray, and at the same time, the soil on the seedling tray that deviates from the seedling hole can fall back into the seedling hole.

[0071] The rotating component 95 includes a support base 951, a rotating shaft 952, a rotating rod 953, a rotating support rod 954, and a moving component 955. The support base 951 is fixedly installed on the conveyor table 2, and one end of the rotating shaft 952 is fixedly connected to the support base 951. The rotating rod 953 is L-shaped and is rotatably sleeved on the outside of the rotating shaft 952. There are two rotating support rods 954, and one end of the two rotating support rods 954 is rotatably connected to one end of the rotating rod 953 through a pin. The other ends of the two rotating support rods 954 are fixedly connected to each other by a synchronous shaft, which slides through the stretching port 941. The moving component 955 is installed on the other end of the rotating rod 953.

[0072] The movable component 955 includes a movable rod 9551, and the other end of the rotating rod 953 is provided with a sliding opening. The movable rod 9551 slides through the sliding opening, and one end of the movable rod 9551 is fixedly connected to the adjacent connecting rod 97.

[0073] Specific implementation process: After seeds have been sown into a row of holes in the seed tray, as the two push blocks 53 move the synchronous plate 41 upward, the two tension rods 94 move upward relative to the synchronous shaft through their tension openings 941. At the same time, under the limiting action of the synchronous shaft, the rotating rod 953 rotates around the rotating shaft 952. While the rotating rod 953 is rotating, it pushes the adjacent connecting rod 97 through the moving rod 9551 at the sliding opening, further causing multiple bulldozer blocks 93 to move relative to the guide shell 92 until the bulldozer hole 931 of the bulldozer block 93 moves to the feed inlet 921 of the guide shell 92. Soil then falls into the bulldozer hole 931. As the push block 53 moves downward, the row of holes into which seeds have been sown moves below the feed inlet. At this time, the push hole of the bulldozer block 93 moves synchronously above the holes, so that a certain amount of soil can be evenly covered into the holes, achieving the purpose of covering the seeds with soil.

[0074] Example 2

[0075] Please see Figure 14 Example 2 further supplements the description of the soil guide component 96 in Example 1. Specifically, the soil guide component 96 includes a feed pipe 961, a guide cylinder 962, a discharge pipe 963, a spiral blade 964, a rotating rod 965, and a rotating motor 966. The top of the feed pipe 961 is connected to one end of the bottom of the discharge hopper 91, and the other end of the feed pipe 961 is connected to the guide cylinder 962. The guide cylinder 962 is installed above the conveyor table 2. There are multiple discharge pipes 963, which are distributed at equal intervals at the bottom of the guide cylinder 962 and are connected to the guide cylinder 962. The bottom of the discharge pipe 963 is connected to the guide shell 92, that is, the discharge pipe 963 is used to support and fix the guide shell 92.

[0076] The rotating rod 965 is rotatably connected inside the guide tube 962, and the rotating motor 966 is mounted on the guide tube 962. The rotating motor 966 is used to drive the rotating rod 965, and the spiral blade 964 is fixedly mounted on the outside of the rotating rod 965.

[0077] Specific implementation process: When soil is filled into the multiple guide shells 92, the rotary motor 966 runs, which causes the rotating rod 965 to drive the spiral blade 964 to rotate relative to the guide cylinder 962. While the spiral blade 964 is rotating, the soil enters the guide cylinder 962 through the hopper 91 and the feed pipe 961, and then enters the guide shell 92 in sequence through multiple feed pipes 963.
