Description

Technical Field

[0001] This utility model relates to the field of agricultural seeding technology, and more specifically, to a modular agricultural seeder for directional delivery. Background Technology

[0002] In current agricultural planting practices, seeders have become a widely used key piece of equipment. Traditional sowing methods mainly rely on manual labor, which is inefficient and the sowing quality is difficult to guarantee. With the development of large-scale and modern agriculture, seeders have emerged. Agricultural seeders are generally composed of seed boxes, seed metering devices, furrow openers, soil covering devices, and compaction wheels. Seed boxes are used to store seeds. Seed metering devices discharge seeds in a certain quantity and at certain intervals. Furrow openers create sowing furrows in the soil. After the seeds fall into the furrows, the soil covering devices cover the seeds with soil. The compaction wheels compact the soil after sowing, making the seeds in close contact with the soil, which is conducive to seed water absorption and germination.

[0003] Considering that different types of seeds have vastly different suitable sowing quantities, such as larger corn seeds, 2-3 seeds per hole are sufficient to meet growth needs, while smaller cabbage seeds often require 5-8 seeds per hole to ensure germination rate. Furthermore, seed shapes vary greatly, with round pea seeds and flat soybean seeds requiring different seed-distribution mechanisms during sowing. Traditional seeders struggle to accurately adapt to these complex and varied seed characteristics, often resulting in inaccurate sowing quantities and uneven seed distribution, which significantly affects crop germination rate and subsequent uniformity of growth. Therefore, we propose a modular agricultural seeder with directional delivery. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned shortcomings. Different types of seeds have different sowing quantities and shapes, and different requirements for the seeding mechanism. Traditional seeders are difficult to adapt accurately, which can easily lead to inaccurate sowing quantities and uneven distribution, affecting the germination rate and crop growth uniformity.

[0005] To achieve the above objectives, this utility model provides a modular agricultural seeder for directional delivery, including a support frame body, a connecting frame fixedly connected to the surface of the support frame body, rollers rotatably connected to both ends of the support frame body, multiple pressing wheels fixedly connected to the surface of the support frame body, multiple seeding components provided on the surface of the support frame body, and a material distributing component provided on the inner wall of each of the multiple seeding components, with the material distributing component located above the support frame body;

[0006] The material distribution component includes an inclined material distribution frame located above the main support frame and in an inclined state. The surface of the inclined material distribution frame is provided with multiple material distribution slots. The inner walls of the multiple material distribution slots are all fixedly connected with feeding barrels, and the lengths of the multiple feeding barrels are different, so that they can be connected to the inner wall of the seeding component.

[0007] By installing the connecting frame at a specific connection point on the seeding vehicle, the power of the seeding vehicle drives the main body of the support frame forward, while the rollers at both ends of the main body of the support frame roll on the ground. This not only enables convenient movement of the equipment but also provides stable support for the entire equipment during movement. The inclined design of the inclined distribution frame utilizes gravity to allow the seeds poured into it to slide down the inclined surface in an orderly manner, flowing into multiple distribution troughs, and then being sent to the seeding assembly via the feeding bucket. This allows for the simultaneous supply of seeds to multiple seeding assemblies, greatly improving the feeding efficiency.

[0008] As a further improvement to this technical solution, a feed pipe is fixedly connected to the end of the inclined material distribution frame, and the feed pipe is located at the highest point of the inclined part of the inclined material distribution frame.

[0009] Each of the multiple material distribution troughs has a protective frame fixedly connected to its inner wall. The gaps between the multiple protective frames are not consistent. Along the inclined surface of the material distribution frame from high to low, the gaps between the protective frames gradually increase from small to large.

[0010] By setting the structure and varying the gaps of the protective frame, seeds are prevented from being overly concentrated in the front distribution trough, thus achieving a more reasonable and even distribution of seeds among multiple distribution troughs.

[0011] As a further improvement to this technical solution, the seeding assembly includes a seeding pipe fixedly connected to the surface of the feeding hopper, the surface of the seeding pipe fixedly connected to the surface of the support frame body, a rotating frame fixedly connected to the inner cavity of the seeding pipe, a material control plate rotatably connected to the inner wall of the rotating frame, and a connecting rod fixedly connected to the end of the material control plate through the surface of the seeding pipe.

[0012] The connecting rods are multiple rods used to connect multiple control plates and simultaneously control the seed sowing quantity in the inner cavities of multiple seeding pipes;

[0013] A motor is fixedly connected to the surface of the main body of the support frame, and the output end of the motor is fixedly connected to the end of the connecting rod.

[0014] Rotating the connecting rod can drive the control plate to rotate on the inner wall of the rotating frame. When the control plate rotates to different tilt angles, the number of seeds sown in the seeding tube can be controlled. That is, by using the tilt state of the control plate, the passage space and flow speed of the seeds in the seeding tube can be changed, thereby adjusting the number of seeds sown.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This modular agricultural seeder with directional seeding features an inclined feeding rack that simultaneously supplies seeds to multiple seeding modules. Gravity allows the seeds to slide down naturally and flow orderly into the feeding trough, then through the feeding bucket to the seeding modules, greatly improving feeding efficiency. The seeding modules can adapt to different seed types, precisely matching various seed sizes, shapes, and optimal seeding quantities. Connected to the seeding vehicle via a connecting frame, the rollers at both ends of the support frame provide stable support as the seeding vehicle moves, while multiple pressure rollers ensure the equipment's stability during operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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.

[0028] Example

[0029] Please see Figures 1-6 As shown, this embodiment provides a modular agricultural seeder for directional delivery, including a support frame body 1, a connecting frame 10 fixedly connected to the surface of the support frame body 1, rollers 11 rotatably connected to both ends of the support frame body 1, multiple pressing wheels 12 fixedly connected to the surface of the support frame body 1, multiple seeding components 3 provided on the surface of the support frame body 1, and a material distribution component 2 provided on the inner wall of each of the multiple seeding components 3, with the material distribution component 2 located above the support frame body 1;

[0030] The material distribution component 2 includes an inclined material distribution frame 21 located above the support frame body 1 and in an inclined state. The surface of the inclined material distribution frame 21 is provided with multiple material distribution grooves 210. The inner walls of the multiple material distribution grooves 210 are all fixedly connected with feeding barrels 23, and the lengths of the multiple feeding barrels 23 are different, so that they can be connected to the inner wall of the seeding component 3.

[0031] The connecting frame 10 is installed at a specific connection point of the seeding vehicle. When the seeding vehicle starts and moves, the connecting frame 10 moves accordingly, thereby driving the support frame body 1 connected to it to move forward synchronously. During this process, the rollers 11 at both ends of the support frame body 1 roll on the ground, providing stable support for the support frame body 1 and ensuring the smooth operation of the equipment. The seeds to be sown are poured into the inclined distribution frame 21 located above the support frame body 1. Since the inclined distribution frame 21 is inclined, the seeds slide down naturally along the inclined surface under the action of gravity and flow into the multiple distribution grooves 210 opened on the surface of the inclined distribution frame 21 in an orderly manner. Subsequently, the seeds enter the feeding bucket 23 fixedly connected to the inner wall through the distribution grooves 210. Under the guidance of the feeding bucket 23, the seeds finally reach the seeding assembly 3. The inclined setting of the inclined distribution frame 21 can supply seeds to multiple seeding assemblies 3 at the same time, which greatly improves the feeding efficiency. The seeding assembly 3 can accurately control the number of seeds sown according to the actual agronomic needs.

[0032] The improvement in this embodiment is as follows:

[0033] Considering that different types of seeds have vastly different suitable sowing quantities, for example, larger corn seeds only require 2-3 seeds per hole to meet their growth needs, while smaller cabbage seeds often require 5-8 seeds per hole to ensure germination rate. Furthermore, seed shapes vary greatly; round pea seeds and flat soybean seeds require different seed-distribution mechanisms during sowing. Traditional seeders struggle to accurately adapt to these complex and varied seed characteristics, often resulting in inaccurate sowing quantities and uneven seed distribution, significantly impacting crop germination rate and subsequent uniformity of growth. Therefore, by incorporating a tilting feed distribution mechanism… The frame 21 is tilted and can supply seeds to multiple seeding components 3 simultaneously. Gravity allows the seeds to slide down naturally and flow into the distribution trough 210 in an orderly manner. The seeds then reach the seeding components 3 through the feeding bucket 23, which greatly improves the feeding efficiency. At the same time, the seeding components 3 can adapt to the sowing needs of different types of seeds. Whether it is seeds of different sizes and shapes or different suitable sowing quantities, they can be accurately matched. The frame 21 is connected to the seeding vehicle through the connecting frame 10. When the seeding vehicle moves, the rollers 11 at both ends of the support frame body 1 roll on the ground to provide stable support. There are also multiple press wheels 12 to ensure the stability of the equipment during operation.

[0034] In order for the seed distribution component 2 to transfer seeds to the inclined seed distribution frame 21, a feed pipe 211 is fixedly connected to the end of the inclined seed distribution frame 21. The feed pipe 211 is located at the highest point of the inclined portion of the inclined seed distribution frame 21. By connecting the output end of the seed box to the feed pipe 211 and driving the drive component inside the seed box, the seeds can enter the inclined seed distribution frame 21 through the feed pipe 211. Since the feed pipe 211 is located at the highest point of the inclined seed distribution frame 21, the seeds at the highest point will move towards the bottom of the inclined seed distribution frame 21 under the action of gravity. During this process, the seed distribution trough 210 will receive the moving seeds.

[0035] To prevent most seeds from flowing into the front-end distribution trough 210 during the movement of seeds within the inclined distribution rack 21, protective frames 22 are fixedly connected to the inner walls of multiple distribution troughs 210. The gaps between the protective frames 22 are not uniform; they gradually increase from high to low along the surface of the inclined distribution rack 21. By setting the structure and gap variation of the protective frames 22, excessive concentration of seeds in the front-end distribution trough 210 is avoided, achieving a more reasonable and even distribution of seeds among the multiple distribution troughs 210.

[0036] In order for the seeding assembly 3 to seed, the parts of the seeding assembly 3 need to be further disclosed. Therefore, the seeding assembly 3 includes a seeding pipe 31 fixedly connected to the surface of the feeding hopper 23. The surface of the seeding pipe 31 is fixedly connected to the surface of the support frame body 1. A rotating frame 32 is fixedly connected to the inner cavity of the seeding pipe 31. A material control plate 33 is rotatably connected to the inner wall of the rotating frame 32. A connecting rod 34 is fixedly connected to the end of the material control plate 33 through the surface of the seeding pipe 31.

[0037] The connecting rod 34 is used to connect multiple control plates 33 together, and at the same time control the seed sowing quantity in the inner cavity of multiple seeding tubes 31;

[0038] By rotating the connecting rod 34 by external force, the control plate 33 can be driven to rotate on the inner wall of the rotating frame 32. When the control plate 33 rotates to different tilt angles, the number of seeds sown in the seeding tube 31 can be controlled. That is, by using the tilt state of the control plate 33, the passage space and flow speed of the seeds in the seeding tube 31 can be changed, thereby precisely adjusting the number of seeds sown.

[0039] In order to enable the connecting rod 34 to rotate and thus adjust the seed sowing quantity, a motor 35 is fixedly connected to the surface of the support frame body 1. The output end of the motor 35 is fixedly connected to the end of the connecting rod 34. The operation of the motor 35 can drive the connecting rod 34 to rotate. At this time, the rotation of the connecting rod 34 can drive the material control plate 33 to rotate on the inner wall of the rotating frame 32.

[0040] In practical use, the modular agricultural seeder with directional delivery of this utility model first installs the connecting frame 10 at a specific connection point on the seeder vehicle. When the seeder vehicle starts and moves, the connecting frame 10 moves accordingly, thereby driving the connected support frame body 1 to move forward synchronously. During this process, the rollers 11 at both ends of the support frame body 1 roll on the ground. At this time, the seeds to be sown are poured into the inclined distribution frame 21 located above the support frame body 1. Since the inclined distribution frame 21 is inclined, the seeds slide down the inclined surface naturally under the action of gravity and flow into the inclined surface in an orderly manner. Seeds entering the multiple distribution slots 210 on the surface of the distribution rack 21 will pass through the gaps on the surface of the protective rack 22 into the feeding bucket 23 and reach the inner cavity of the seeding pipe 31. By rotating the connecting rod 34 by external force, the control plate 33 can be rotated on the inner wall of the rotating frame 32. When the control plate 33 is rotated to different tilt angles, the number of seeds sown in the seeding pipe 31 can be controlled. That is, by using the tilt state of the control plate 33, the passage space and flow speed of the seeds in the seeding pipe 31 are changed, thereby adjusting the number of seeds sown.
