Description

Technical Field

[0001] This utility model relates to the field of soybean planting technology, and in particular to a soybean planter. Background Technology

[0002] Soybean cultivation is an important agricultural production activity, widely distributed in temperate and subtropical regions. Soybeans prefer warm and humid climates and thrive in deep, well-drained loam. Sowing time is mostly in spring or early summer, using row sowing or hill sowing methods. During the growing season, proper fertilization is necessary. Modern cultivation mostly adopts mechanized operations, combined with improved variety selection and water-saving irrigation techniques, yields can reach 150 to 300 kilograms per mu. As an important oilseed and protein crop, soybeans have significant economic value in food processing, feed production, and bioenergy.

[0003] In the prior art, when using mechanical devices to sow soybean seeds, the seeds are usually placed in the device and then dropped into the soil by rotating the device. However, the capacity of the seed-carrying mechanism in the device is often fixed and cannot be changed according to different sowing needs, resulting in poor applicability of the device. Different sowing devices need to be replaced according to actual needs, which affects the seed sowing efficiency. Therefore, in order to solve the above problems, this utility model proposes a soybean planting seeder. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a soybean planter that uses a servo motor to drive a turntable. During the turntable's rotation, the connection between the arc-shaped rod and the connecting block causes the slider to move in the groove, adjusting the seeding amount of the seeding roller to meet different usage needs, enhancing the applicability of the device, avoiding the need to replace different seeding mechanisms, and improving seeding efficiency.

[0005] This utility model provides the following technical solution: A soybean planter includes a fixed cylinder. The inner cavity of the fixed cylinder has an inlet and an outlet respectively. A feed hopper is fixedly connected to the upper part of the inlet. A drive motor is fixedly installed at the rear of the fixed cylinder. The output shaft of the drive motor is movably sleeved on the rear of the inner cavity of the fixed cylinder. A gear one is fixedly sleeved on the output shaft of the drive motor. A gear two meshes with the outer edge of the gear one. A rotating shaft one is fixedly sleeved in the middle of the gear two. The rotating shaft one is movably sleeved in the inner cavity of the fixed cylinder. A planting roller is fixedly sleeved in the middle of the rotating shaft one. Sliding grooves are evenly distributed on the planting roller. A servo motor is fixedly installed in the inner cavity of the planting roller. The motor, specifically the servo motor, has its output shaft movably fitted inside the sowing roller cavity. Four turntables are evenly fixedly fitted onto the servo motor's output shaft. Six arc-shaped rods are evenly and movably connected to each turntable via shafts. A connecting block is movably connected to the end of each arc-shaped rod away from the turntable via a shaft. A slider is fixedly installed on the side of the connecting block away from the arc-shaped rod, and the slider is movably connected in a groove. The servo motor drives the turntable to rotate. During the rotation of the turntable, the connection between the arc-shaped rods and the connecting block causes the slider to move within the groove, adjusting the sowing amount of the sowing roller to meet different usage needs, enhancing the applicability of the device, and avoiding the need to replace different sowing mechanisms.

[0006] Preferably, a housing is fixedly installed on the right side of the fixed cylinder, and electric push rods are evenly fixedly installed on the top of the inner cavity of the housing. There are three electric push rods, and a lifting plate is fixedly installed on the telescopic end of each electric push rod. The lifting plate is moved by the telescopic end of the electric push rod, thereby adjusting the height of the plow blade and improving the flexibility of the plow blade to cope with soils of different hardness, so that the device can achieve a good plowing effect on the soil.

[0007] Preferably, four plow blades are evenly and fixedly installed at the bottom of the lifting plate. The front and rear parts of the housing are respectively connected to rollers via shafts. By setting multiple sets of plow blades, four rows of seeds can be sown simultaneously during the movement of the device, which helps to improve the sowing efficiency of the device.

[0008] Preferably, a connecting seat is fixedly installed on the left side of the fixed cylinder. The front and rear parts of the connecting seat are respectively movably connected to two rollers via shafts. A handrail is fixedly installed on the upper part of the connecting seat, and a control panel is fixedly installed on the upper part of the handrail. After the soybean seeds fall into the soil, the user pushes the device to move by the handrail, so that the bottom of the connecting seat flattens and fills the gaps in the soil, thereby completing the sowing operation.

[0009] Compared with the prior art, the advantages of this utility model are as follows:

[0010] 1. The turntable is driven to rotate by a servo motor. During the rotation of the turntable, the connection between the arc rod and the connecting block drives the slider to move in the groove. When the slider moves to the outside of the seeding roller, the capacity in the groove decreases. When the slider moves to the inside of the seeding roller, the capacity in the groove increases. This allows for the adjustment of the seeding quantity of the seeding roller to meet different seeding quantity requirements. This enhances the applicability of the seeding device, avoids the need to replace different seeding mechanisms, and effectively improves the seeding efficiency.

[0011] 2. The extension and retraction of the electric push rod is controlled via the control panel, which allows the lifting plate to adjust the height of the plow blade. This improves the flexibility of the plow blade and enhances the device's overall flexibility, enabling it to handle soils of varying hardness and achieve optimal plowing results. This, in turn, assists in the sowing of soybean seeds and prevents insufficient sowing depth. The user pushes the device using the handle to separate the soil with the plow blade. During the device's movement, the bottom of the connecting seat can level and fill any gaps in the soil, thus completing the sowing operation. Attached Figure Description

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] Please see Figures 1-4A soybean planter includes a fixed cylinder 1, characterized in that: the inner cavity of the fixed cylinder 1 is provided with an inlet 2 and an outlet 3 respectively; an inlet hopper 4 is fixedly connected to the upper part of the inlet 2; a drive motor 5 is fixedly installed at the rear of the fixed cylinder 1; the output shaft of the drive motor 5 is movably sleeved at the rear of the inner cavity of the fixed cylinder 1; a gear 6 is fixedly sleeved on the output shaft of the drive motor 5; a gear 7 is meshed with the outer edge of the gear 6; a rotating shaft 8 is fixedly sleeved in the middle of the gear 7; and the rotating shaft 8 is movably sleeved on the fixed cylinder 1. Inside the fixed cylinder 1, a seeding roller 9 is fixedly sleeved at the middle of the rotating shaft 8. Sliding grooves 10 are evenly distributed on the seeding roller 9. A servo motor 11 is fixedly installed inside the seeding roller 9. The output shaft of the servo motor 11 is movably sleeved within the seeding roller 9. Four turntables 12 are evenly fixedly sleeved on the output shaft of the servo motor 11. Six arc-shaped rods 13 are evenly movably connected to each turntable 12 via shafts. The end of each arc-shaped rod 13 furthest from the turntable 12 is movably connected to a connecting rod via a shaft. A slider 15 is fixedly installed on the side of the connecting block 14 away from the arc rod 13. The slider 15 is movably connected in the chute 10. When soybean seeds are added to the feed hopper 4, the drive motor 5 is started to drive the gear 6 to rotate. The gear 6 meshes with the gear 7 to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the sowing roller 9 to rotate, so that the chute 10 on the sowing roller 9 rotates to the feed inlet 2, allowing the soybean seeds to enter the chute 10. When the chute 10 rotates to the discharge outlet 3, the soybean seeds fall from the chute 10 into the soil. When it is necessary to adjust the seed content in the chute 10, the servo motor 11 drives the turntable 12 to rotate. During the rotation of the turntable 12, the connection between the arc rod 13 and the connecting block 14 is used to drive the slider 15 to move in the chute 10, adjusting the capacity of the chute 10 and thus adjusting the seed quantity to meet different actual needs. This avoids the need to replace different sowing mechanisms, which helps to enhance the applicability of the sowing device and effectively improves the sowing efficiency.

[0019] A housing 16 is fixedly installed on the right side of the fixed cylinder 1. Three electric push rods 17 are evenly fixedly installed on the top of the inner cavity of the housing 16. A lifting plate 18 is fixedly installed on the telescopic end of each electric push rod 17. Four plow blades 19 are evenly fixedly installed on the bottom of the lifting plate 18. Rollers 20 are movably connected to the front and rear parts of the housing 16 via shafts. A connecting seat 21 is fixedly installed on the left side of the fixed cylinder 1. Rollers 22 are movably connected to the front and rear parts of the connecting seat 21 via shafts. A handrail 23 is fixedly installed on the upper part of the connecting seat 21. Equipped with a control panel 24, the extension and retraction ends of the electric push rod 17 are controlled via the control panel 24, causing the lifting plate 18 to drive the plow blade 19 to adjust its height. This improves the flexibility of the plow blade 19, enhancing the device's adaptability to soils of varying hardness and enabling it to achieve good plowing results. This, in turn, assists in the sowing of soybean seeds, preventing insufficient sowing depth. The user uses the handle 23 to push the device, causing the plow blade 19 to separate the soil. During the device's movement, the bottom of the connecting seat 21 can flatten and fill the gaps in the soil, thus completing the sowing operation.

[0020] Working principle: Soybean seeds are added to the feed hopper 4. The extension and retraction end of the electric push rod 17 is controlled by the control panel 24, which causes the lifting plate 18 to drive the plow blade 19 to adjust its height. The user uses the handle 23 to push the device, causing the plow blade 19 to separate the soil. The drive motor 5 is started, which drives the gear 6 to rotate. The gear 6 meshes with the gear 7, which drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the sowing roller 9 to rotate, causing the chute 10 on the sowing roller 9 to rotate to the feed inlet 2, allowing the soybean seeds to enter the chute 10. When the chute 10 rotates... When the device moves to the discharge port 3, the soybean seeds fall from the chute 10 into the soil gaps formed by the plow blade 19. During the movement of the device, the bottom of the connecting seat 21 can flatten and fill the soil gaps, thereby completing the sowing operation. When it is necessary to adjust the seed content in the chute 10, the servo motor 11 drives the turntable 12 to rotate. During the rotation of the turntable 12, the arc rod 13 is connected to the connecting block 14, thereby driving the slider 15 to move in the chute 10, adjusting the capacity of the chute 10, and thus adjusting the number of seeds.
