Description

Technical Field

[0001] This utility model relates to the field of soybean planting technology, and in particular to a hand-push roller seeder for soybean planting. Background Technology

[0002] In modern agricultural production, soybeans are an important food and oilseed crop, and the sowing process has a crucial impact on subsequent growth and yield. Currently, soybean sowing equipment is mainly divided into two types: manual sowing and large-scale mechanized sowing. Although manual sowing is highly flexible, it suffers from low efficiency, high labor intensity, and difficulty in maintaining consistent sowing spacing and depth, resulting in low germination rates and uneven growth. On the other hand, while large-scale mechanized sowing equipment can achieve high efficiency and large-scale sowing, the equipment is expensive and only suitable for flat, large-area farmland. For mountainous areas, hilly areas, small-scale farmland, or family farms, there are limitations such as difficulty in accessing the equipment, inconvenient operation, and high maintenance costs, which cannot meet the diverse planting needs. Existing small-scale seeding equipment, such as some simple hand-push seeders, typically uses a simple gravity or mechanical paddle mechanism for seed dispensing. This makes it difficult to accurately control the amount and spacing of seeds, which can easily lead to missed sowing, double sowing, or uneven sowing, affecting the planting density and growth of soybeans. In addition, the soil covering structure of these devices is mostly designed with a fixed height, which cannot adjust the soil covering depth according to different soil conditions, seed characteristics, and agronomic requirements. This results in unstable seed germination rates and poor adaptability when operating on complex terrain or plots with different soil types.

[0003] Therefore, a hand-push roller seeder for soybean planting is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a hand-push roller seeder for soybean planting, which can solve the problems of existing seeders that are difficult to accurately control the amount and spacing of seeds, which easily leads to missed sowing, double sowing or uneven sowing, affecting the planting density and growth effect of soybeans. In addition, the soil covering structure of such equipment is mostly designed with a fixed height, which cannot adjust the soil covering depth according to different soil conditions, seed characteristics and agronomic requirements, resulting in unstable seed germination rate and poor adaptability when operating on complex terrain or plots with different soil types.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hand-push roller seeder for soybean planting, comprising a main shaft, a movable wheel rotatably connected to the middle of the surface of the main shaft via a bearing, seeding components being provided at both ends of the main shaft, and a soil covering component being provided at the rear side of the seeding components, the soil covering component including a support plate; The seeding assembly includes an installation cavity, with a material cylinder fixedly connected to the top of the installation cavity. A turntable is provided inside the installation cavity, and a connecting shaft is fixedly connected to the center of the turntable. The connecting shaft passes through the installation cavity and rotates with the installation cavity via a bearing. Seed slots are provided on the surface of the turntable, and the number of seed slots is set to multiple and evenly distributed. A drop outlet is provided at the bottom of the installation cavity and is used in conjunction with the seed slots.

[0006] Preferably, the support plate is fixedly connected to the rear side of the mounting cavity surface, and a soil covering plate is provided below the support plate and is used in conjunction with the sowing component.

[0007] Preferably, the support plate is internally threaded with a screw rod, the back side of the soil covering plate is fixedly connected to a fixing block, and the bottom end of the screw rod is rotatably connected to the inside of the top of the fixing block.

[0008] Preferably, a limiting rod is movably connected inside the support plate, and the limiting rod is fixedly connected to the fixing block on the side near the fixing block.

[0009] Preferably, the spindle has an internal cavity and a connecting shaft is movably connected inside the spindle, and the spindle has a threaded fastening screw inside.

[0010] Preferably, the surface of the connecting shaft is provided with multiple threaded grooves, and the threaded grooves are used in conjunction with fastening screws.

[0011] Preferably, the top of the material cylinder is provided with a cap, and both the material cylinder and the cap are made of transparent acrylic material.

[0012] Preferably, a push handle is fixedly connected to the rear side of the spindle surface, and a rubber pad is fitted onto the surface of the push handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This application sets up a sowing component, which adopts a turntable design with seed troughs. Multiple evenly distributed seed troughs on the surface of the turntable can ensure that each sowing is a single seed or a preset number, effectively avoiding missed sowing and double sowing, accurately controlling the sowing spacing and density, making the soybean plants evenly distributed, making full use of soil nutrients and light resources, improving the emergence rate and crop growth consistency, and laying the foundation for subsequent yield increase. 2. This application sets up a soil covering component, which is connected to the support plate by a screw. This allows for flexible adjustment of the soil covering plate height, accurately matching the optimal soil covering depth requirements for soybean seeds. This ensures that the seeds receive a suitable covering thickness, effectively avoiding problems such as seed rot due to excessive soil covering or seed dehydration and damage from birds and animals due to insufficient soil covering. This significantly improves seed germination rate and seedling survival rate. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] Please see Figure 1-5 The present invention provides the following technical solution: A hand-push roller seeder for soybean planting includes a main shaft 1, a movable wheel 2 rotatably connected to the middle of the surface of the main shaft 1 via a bearing, a sowing component 3 is provided at both ends of the main shaft 1, and a soil covering component 4 is provided on the rear side of the sowing component 3, the soil covering component 4 including a support plate 401. The seeding assembly 3 includes an installation cavity 301, with a material cylinder 302 fixedly connected to the top of the installation cavity 301. A turntable 303 is provided inside the installation cavity 301, and a connecting shaft 304 is fixedly connected to the middle of the turntable 303. The connecting shaft 304 passes through the installation cavity 301 and rotates with the installation cavity 301 through a bearing. Seed grooves 305 are provided on the surface of the turntable 303. The number of seed grooves 305 is set to multiple and evenly distributed. A drop outlet 306 is provided at the bottom of the installation cavity 301 and is used in conjunction with the seed grooves 305.

[0018] In this embodiment: by setting the sowing component 3, the mounting cavity 301 can provide installation space and support for components such as the turntable 303 and the connecting shaft 304, ensuring the stable operation of each component. The feed cylinder 302 is used to store soybean seeds, allowing the seeds to fall smoothly into the mounting cavity 301 under their own weight, continuously supplying seeds to the seed trough 305 on the turntable 303, ensuring the continuity of the sowing process. During sowing, the turntable 303 will rotate with the connecting shaft 304, and the seed trough 305 will sequentially pass under the feed cylinder 302 to fill with seeds. When it rotates to align with the drop-out port 306 at the bottom of the mounting cavity 301, the seeds are released. Due to gravity, the seeds fall into the sowing furrow. By rationally designing the number, size, and distribution of seed troughs 305, the sowing spacing and density can be precisely controlled to ensure that each seed maintains a suitable distance, thereby improving sowing quality. The connecting shaft 304 plays a role in connection and transmission. On the one hand, it can transmit the power of the main shaft 1 to the turntable 303, enabling the turntable 303 to rotate. On the other hand, the connecting shaft 304 is fixed to the inside of the main shaft 1 by fastening screws 5 and threaded grooves 6. Different specifications of turntables 303 can be quickly replaced according to different sowing needs, thereby adjusting the sowing parameters and improving the applicability and flexibility of the equipment.

[0019] Specifically, such as Figure 4 As shown, the support plate 401 is fixedly connected to the rear side of the surface of the mounting cavity 301, and a soil covering plate 402 is provided below the support plate 401 and is used in conjunction with the sowing component 3.

[0020] Specifically, such as Figure 4 As shown, the support plate 401 is internally threaded with a screw 403, and the back side of the soil covering plate 402 is fixedly connected with a fixing block 404. The bottom end of the screw 403 is rotatably connected to the inside of the top of the fixing block 404.

[0021] Specifically, such as Figure 4 As shown, a limiting rod 405 is movably connected inside the support plate 401, and the side of the limiting rod 405 near the fixing block 404 is fixedly connected to the fixing block 404.

[0022] In this embodiment: With the above configuration, the support plate 401 serves as the basic support structure for the soil covering assembly 4. It provides an installation carrier for the screw 403, the limiting rod 405, and the soil covering plate 402, ensuring a tight fit between the soil covering assembly 4 and the sowing assembly 3. The soil covering plate 402 is located below the support plate 401 and can directly contact the soil. As the seeder moves forward, the soil covering plate 402 gathers the soil from both sides of the furrow opened by the rollers and covers the seeds, completing the soil covering process after sowing. The operator can rotate the screw 403, using the threaded transmission principle to move the fixed block 404 and the soil covering plate 402 up and down. The rotating connection design of the screw 403 ensures its own rotation... Meanwhile, the vertical displacement can be accurately transmitted to the covering plate 402, allowing operators to quickly adapt to different soil conditions, seed types, or agronomic requirements without the need for complex tools, flexibly change the covering depth, and improve the applicability of the equipment. The limiting rod 405 can guide and stabilize the movement of the covering plate 402. When adjusting the height of the covering plate 402, the limiting rod 405 can restrict the fixed block 404 and the covering plate 402 to move only in the vertical direction, preventing them from shifting or shaking in the horizontal direction, ensuring that the covering plate 402 always maintains a stable working posture, thus making the height adjustment process of the covering plate 402 smoother and improving the convenience of operation and adjustment accuracy.

[0023] Specifically, such as Figure 5 As shown, the spindle 1 has an internal cavity and the connecting shaft 304 is movably connected inside the spindle 1. The spindle 1 has a threaded connection with a fastening screw 5.

[0024] Specifically, such as Figure 5 As shown, the surface of the connecting shaft 304 is provided with multiple threaded grooves 6, and the threaded grooves 6 are used in conjunction with the fastening screws 5.

[0025] In this embodiment: With the above settings, the connecting shaft 304 is a key component that transmits power from the main shaft 1 to the turntable 303. When the main shaft 1 rotates with the moving wheel 2, the connecting shaft 304 rotates synchronously, driving the turntable 303 to rotate and realize the seeding function. The multiple threaded grooves 6 on the surface of the connecting shaft 304 can cooperate with the fastening screws 5 to lock the connecting shaft 304 in a specific position within the main shaft 1, ensuring the reliability of power transmission. At the same time, by loosening the fastening screws 5, the axial position of the connecting shaft 304 within the main shaft 1 can be easily adjusted, thereby allowing for flexible adjustment of the spacing between the two sets of seeding components 3 to adapt to different seeding needs and improve versatility.

[0026] Specifically, such as Figure 2 As shown, the top of the material cylinder 302 is provided with a cap 7, and both the material cylinder 302 and the cap 7 are made of transparent acrylic material.

[0027] Specifically, such as Figure 2As shown, push handles 8 are fixedly connected to the rear side of the surface of the spindle 1, and rubber pads are fitted onto the surface of the push handles 8.

[0028] In this embodiment: By setting up the material cylinder 302 and the cover 7, the transparent acrylic material cylinder 302 and the cover 7 allow the operator to easily observe the seed level inside in real time. The operator can promptly detect seed shortages without opening the cover 7, avoiding missed sowing due to seed shortages and improving sowing efficiency. The cover 7 can prevent seeds from spilling out due to vibration or wind during the overall movement of the seeder, ensuring a stable seed level. At the same time, it can also block dust and moisture from entering to a certain extent, keeping the seeds dry, which is especially suitable for humid environments or rainy season operations. By setting up the push handle 8, the push handle 8 can provide the operator with a force point to easily push the seeder forward. The rubber pad on its surface can effectively buffer the vibration between the hand and the push handle 8, reducing discomfort to the operator's hands and arms during long-term operation. Secondly, the rubber pad can also ensure that the operator can firmly hold the push handle 8, preventing slippage and loss of control, and improving the comfort of holding.

[0029] Working principle: First, pour soybeans into the feed cylinder 302, then tighten the sealing cap 7. Next, rotate the screw 403. As the screw 403 rotates, it will drive the covering plate 402 to move up or down. The limiting rod 405 ensures that the covering plate 402 moves vertically until the covering plate 402 is adjusted to the target depth. Then, the operator holds the push handle 8 with both hands and pushes the seeder forward slowly. During the movement of the moving wheels 2, the moving wheels 2 will drive the main shaft 1 to rotate. The main shaft 1 will drive the turntable 303 to rotate through the connecting shaft 304. The seed trough 305 rotates with the turntable 303, filling the bottom of the feed cylinder 302 with seeds in sequence. When the rotation reaches the bottom of the mounting cavity 301... When the seed falls into the sowing furrow at the drop outlet 306, the seed will fall into the sowing furrow by gravity. As the seed falls, the seeder continues to move forward. The covering plate 402 will gather the soil on both sides of the sowing furrow and cover the seed, completing the covering process. Since the height of the covering plate 402 has been adjusted in the early stage, the covering thickness can be guaranteed to meet the requirements of soybean sowing, providing good conditions for seed germination. When it is necessary to adjust the spacing between the two sets of sowing components 3, the connecting shaft 304 can be adjusted by loosening the fastening screw 5 inside the main shaft 1 and then tightening the fastening screw 5 again, so that the connecting shaft 304 can be fixed in the appropriate position inside the main shaft 1, thereby determining the appropriate sowing spacing.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
