Abstract
Description
Technical Field
[0001] This utility model relates to the field of seeding device technology, and more specifically, to a uniform seeding device. Background Technology
[0002] In existing technologies, the precision of the seeding rate adjustment mechanism of existing equipment is generally insufficient, making it difficult to meet the precise requirements of different crops for seeding density. Operators often need to make multiple adjustments based on experience to achieve the desired effect. In the context of large-scale mechanized planting, this uneven seeding phenomenon directly leads to uneven seedling emergence in the field. In some areas, the plants are too dense, which intensifies resource competition, while in other areas, the plants are sparse, which leads to waste of land resources. Ultimately, this significantly reduces the yield per unit area and the consistency of crop quality.
[0003] Secondly, existing sowing devices have significant shortcomings in seed dispersion. During storage and transportation, seeds often clump together or clump due to factors such as humidity, temperature changes, or static electricity. This problem is particularly prominent for seeds with high oil content, such as sesame and flax. Traditional sowing equipment often lacks effective seed pretreatment and dispersion mechanisms, making it impossible to fully separate the clumps of seeds before sowing.
[0004] In addition, existing seeding devices still have many defects in the overall seeding function. Many devices lack precision in controlling the seeding depth, resulting in inconsistent seeding depth, which affects the seed germination rate and seedling uniformity. This is especially true in fields with uneven surface or soil texture, where some areas are sown too deep and the seeds are difficult to emerge, while other areas are sown too shallow and are easily affected by the external environment.

[0031] Please see Figures 1-6 A uniform seeding device includes a receiving cylinder 1, on which a seeding assembly is provided. The seeding assembly includes a fixed base 2, a second motor 3, a rotating plate 4, an adjusting rod 5, and a moving rod 6. The fixed base 2 is installed at one end of the receiving cylinder 1, the second motor 3 is fixedly installed on the fixed base 2, the rotating plate 4 is connected to the output end of the second motor 3, the adjusting rod 5 is rotatably connected to the rotating plate 4, and the moving rod 6 is rotatably connected to the adjusting rod 5. A dispersing assembly is provided on the receiving cylinder 1, which includes a support base 7, a mixing cylinder 8, and a discharge pipe 9. The support base 7 is installed on the top of the receiving cylinder 1, the mixing cylinder 8 is installed on the top of the support base 7, and the discharge pipe 9 is connected between the mixing cylinder 8 and the receiving cylinder 1.
[0032] The fixed base 2 has a movable groove 10, the movable rod 6 is slidably connected to the movable groove 10, and the movable rod 6 passes through the receiving cylinder 1 and is connected to the movable plate 11.
[0033] The movable plate 11 has a material discharge port 12, and the receiving cylinder 1 has a material discharge port 13, which is compatible with the material discharge port 12.
[0034] A valve 14 is installed on the discharge pipe 9, and a first motor 15 is installed on the mixing drum 8. The output end of the first motor 15 is connected to a stirring rod 16.
[0035] A connecting plate 17 is evenly installed on the stirring rod 16, and a stirring blade 18 is installed on the connecting plate 17.
[0036] In this embodiment, when seeds need to be sown during use, since the seeds are placed in the receiving cylinder 1, the second motor 3 is started, causing the rotating plate 4 at the output end to rotate. During this rotation, the adjusting rod 5 on the plate rotates continuously. As the plate rotates, one end of the movable rod 6 connected to the rod slides along the movable groove 10 on the fixed base 2. During this sliding movement, the movable plate 11 connected to the movable rod 6 slides inside the receiving cylinder 1. During this sliding movement, the discharge port 12 on the movable plate 11 and the discharge port 13 on the receiving cylinder 1 continuously converge and then move away, causing... When the discharge port 12 and the unloading port 13 are aligned, the seeds can be discharged from them. When the discharge port 12 and the unloading port 13 are far apart, the seed discharge process stops. During use, the seeds are injected into the mixing drum 8. In order to disperse the seeds that are stuck together, the first motor 15 is started, which drives the mixing rod 16 at the output end to rotate. During the rotation, the connecting plate 17 on it rotates fully, thereby cooperating with the mixing blade 18 to complete the seed scattering process. After the seed scattering process is completed, the valve 14 is opened, so that the seeds can flow into the receiving drum 1 along the discharge pipe 9, thereby promoting the completion of the subsequent seed sowing process.
[0037] Please see Figure 6 As an embodiment of a uniform seeding device for a moving component: a moving component is provided at the bottom of the mixing drum 8. The moving component includes a vehicle body 19, a handle 20 and a moving wheel 21. The vehicle body 19 is provided at the bottom of the mixing drum 8, the handle 20 is connected to one end of the vehicle body 19, and the moving wheel 21 is provided at the bottom of the vehicle body 19.
[0038] A push rod 22 is installed at one end of the vehicle body 19, and a material hopper 23 is connected to the bottom of the receiving cylinder 1. The material hopper 23 is adapted to the discharge port 13, and a material discharge pipe 24 is connected to the bottom of the material hopper 23.

The bottom of the material discharge pipe 24 is located between the traveling wheel 25 and the tilting wheel 26. A rotating blade 27 is installed on one side of the bottom of the vehicle body 19.
[0040] More specifically, during use, the handle 20 is manually supported, and the moving wheels 21 at the bottom of the vehicle body 19 are used to easily move the vehicle body 19. During the movement, the push rod 22 on the vehicle body 19 is used to loosen the soil. During the movement, the seeds continuously flow from the discharge port 12 of the receiving cylinder 1 into the discharge hopper 23, and then flow along the discharge pipe 24 into the inner side of the traveling wheel 25 and the tilting wheel 26. Under the action of the traveling wheel 25 and the tilting wheel 26, the process of digging a hole is completed, so that the seeds can be planted in the hole. The rotating blade 27 is used to easily turn the soil onto the hole, thus completing the planting process.
[0041] In summary, during the use or operation of the overall equipment: When sowing seeds, since the seeds are placed in the receiving cylinder 1, the second motor 3 is started, causing the rotating plate 4 at the output end to rotate. During this rotation, the adjusting rod 5 on the plate rotates continuously. As the plate rotates, one end of the movable rod 6 connected to the rod slides along the movable groove 10 on the fixed base 2. During this sliding movement, the movable plate 11 connected to the movable rod 6 slides inside the receiving cylinder 1. During this sliding movement, the discharge port 12 on the movable plate 11 and the discharge port 13 on the receiving cylinder 1 continuously converge together. When the discharge port 12 and discharge port 13 are aligned, the seeds can leak out. When the discharge port 12 and discharge port 13 are far apart, the seed outflow process stops. During use, the seeds are injected into the mixing drum 8. In order to disperse the seeds that are stuck together, the first motor 15 is started, which drives the mixing rod 16 at the output end to rotate. During the rotation, the connecting plate 17 on it rotates fully, thereby cooperating with the mixing blade 18 to complete the seed scattering process. After the seed scattering process is completed, the valve 14 is opened, so that the seeds can flow into the receiving drum 1 along the discharge pipe 9, thereby promoting the completion of the subsequent seed sowing process.
[0042] During use, the handle 20 is manually supported, and the moving wheels 21 at the bottom of the vehicle body 19 are used to easily move the vehicle body 19. During the movement, the push rod 22 on the vehicle body 19 is used to loosen the soil. During the movement, the seeds continuously flow from the discharge port 12 of the receiving cylinder 1 into the discharge hopper 23, and then flow along the discharge pipe 24 into the inner side of the traveling wheel 25 and the tilting wheel 26. Under the action of the traveling wheel 25 and the tilting wheel 26, the process of digging holes is completed, so that the seeds can be planted in the holes. The rotating blade 27 is used to easily turn the soil onto the holes, thus completing the planting process.
