Abstract
Description
Technical Field
[0001] This application relates to the field of seeders, and in particular to a no-till multi-row seeder. Background Technology
[0002] No-till multi-row seeders are a type of modern agricultural machinery mainly used for efficient sowing directly on untilled soil, such as straw-covered land or land remaining from previous crops. They allow for direct sowing, retaining surface cover, reducing soil disturbance, and have advantages such as moisture retention, erosion prevention, cost reduction, and efficiency improvement.
[0003] A search revealed that CN218417272U discloses a no-till fertilizing corn planter. When planting is required, fertilizer and seeds are first placed in the fertilizer box and seed box, respectively. The water tank is then filled with water. The agricultural machine's traction rod is then inserted into the planter's sleeve. A locking rod is inserted into the locking groove of the sleeve, and a locking ring is used to lock the rod to prevent it from loosening and separating the agricultural machine from the planter. As the agricultural machine moves the planter, the plow blades create furrows in the soil. Fertilizer from the fertilizer box is transported through the fertilizer pipe to the connecting pipe, where it is evenly spread into the furrows. Finally, seeds from the seed box are sown into the furrows through the seeding pipe.
[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist that need improvement: Although the aforementioned device can accurately and evenly spread fertilizer into the furrows, some crops require fertilizer to be applied to deeper layers of soil so that the roots can absorb it better. The aforementioned device does not have the relevant pre-embedded structure, thus it cannot achieve the effect of precise sowing and cannot ensure the consistency of sowing depth.

The above-mentioned device does not have the relevant pre-embedded structure, so it cannot achieve the effect of precise sowing and cannot ensure the consistency of sowing depth.
[0006] This application provides a no-till multi-row seeder, which adopts the following technical solution:
[0007] A no-till multi-row seeder includes a seeding vehicle body, a support arm, a support joint, a swing arm, a pre-embedded component, and a seed spreading component.

[0014] In summary, this application includes at least one of the following beneficial technical effects:
[0015] This device achieves precise deep fertilization and sowing by adding pre-embedded components and optimizing the seed spreading components. When adjusting the furrow depth, the first push cylinder drives the lifting support, which in turn drives the rotating furrowing teeth with a DC motor and drive shaft to dynamically adjust the furrow depth. The serrated blades enhance the stubble breaking ability, and can stably furrow even in straw-covered or compacted soil.

[0031] The seeding vehicle body 1 is used to support the pre-embedded component 5 and the seed material spreading component 6. The seed material spreading component 6 is used to screen the seed material and stably spread the seeds into the soil. The pre-embedded component 5 is used to dig deep trenches in uncultivated land and facilitate the burial of seeds. The support arm 2, together with the support joint 3, is used to adjust the height and angle of the swing arm 4. The swing arm 4 is used to support the pre-embedded component 5.
[0032] The seed spreading assembly 6 includes a feed box 61, a discharge support 62, a guide box 63, a transverse branch pipe 64, and an inverted conical discharge head 65. The feed box 61 is fixedly connected to the top of the seeding vehicle body 1. The discharge support 62 is installed below the feed box 61. The guide box 63 is fixedly connected to the bottom outer side of the discharge support 62. The transverse branch pipe 64 is fixedly connected to the outer side of the discharge port of the guide box 63. The inverted conical discharge head 65 is fixedly connected to the outer side of the transverse branch pipe 64.
[0033] The pre-embedded component 5 includes a positioning frame 51, a first push cylinder 52, a lifting bracket 53, a DC motor 54, a drive shaft 55, and a trenching tooth 56. The positioning frame 51 is fixedly connected to the outside of the swing arm 4. The first push cylinder 52 is installed on the top of the positioning frame 51. The top surface of the lifting bracket 53 is fixedly connected to the output end of the first push cylinder 52. The DC motor 54 is installed on one side of the outer wall of the lifting bracket 53. One end of the drive shaft 55 is fixedly connected to the motor shaft of the DC motor 54 through a coupling. The trenching tooth 56 is sleeved on the outside of the drive shaft 55 and used for trenching the soil.
[0034] The bottom of the grooved tooth 56 is also welded with a serrated cutting edge 7.
[0035] The lower end of the swing arm 4 is also provided with a second lifting cylinder 8, a push rod 9 and a hinged ear plate 10. The hinged ear plate 10 is fixedly connected to the bottom of the swing arm 4. The piston end of the second lifting cylinder 8 is fixedly connected to one end of the push rod 9, and the top of the push rod 9 is hinged to the middle of the hinged ear plate 10.
[0036] The inner side of the feed box 61 is also provided with a screening plate 11 and a vibration motor 12. The screening plate 11 is threaded to the inner side of the feed box 61, and the vibration motor 12 is threaded to the top of the screening plate 11.
[0037] The general process of using the no-till multi-row seeder in this embodiment of the application is as follows:
[0038] The seeder is connected to the tractor, ensuring the seeder body 1 is level and stable. The height of the lifting bracket 53 is adjusted by the first push cylinder 52, and the furrowing depth is set. Seeds or fertilizer are loaded into the feed box 61. Impurities are removed by the screening plate 11 driven by the vibrating motor 12. The dropping position of the inverted conical discharge head 65 is controlled to align it with the groove formed by the furrowing teeth 56. During furrowing and pre-burying, the tractor pulls the seeder forward. The furrowing teeth 56 rotate at high speed driven by the DC motor 54, using the serrated blades 7 to cut the straw and open the furrow. The second lifting cylinder 8 dynamically adjusts the pitch angle of the swing arm 4 through the push rod 9 and the hinged ear plate 10 to adapt to the undulation of the ground and maintain a consistent furrowing depth. Seeds or fertilizer enter the guide box 63 from the feed box 61 through the discharge support 62, and are distributed to each inverted conical discharge head 65 through the transverse branch pipe 64. The discharge head accurately puts the seed or fertilizer into the groove dug by the furrowing teeth 56, realizing deep fertilization or layered sowing. During this process, if the soil hardness changes, the soil penetration pressure of the trenching teeth 56 can be adjusted in real time through the first push cylinder 52, making it convenient to use.
[0039] The beneficial technical effects of the no-till multi-row seeder according to the embodiments of this application are roughly as follows:
[0040] This device achieves precise deep fertilization and sowing by adding pre-embedded components 5 and optimizing seed spreading components 6. When adjusting the furrow depth, the first push cylinder 52 drives the lifting bracket 53, which in turn drives the rotating furrowing teeth 56 via a DC motor 54 and drive shaft 55, thus dynamically adjusting the furrow depth. The serrated blades 7 enhance the stubble breaking ability, ensuring stable furrowing even in straw-covered or compacted soil. The rotating furrowing teeth 56 can break up deep soil and form a loose seedbed, improving the aeration and water permeability around the seeds and promoting root penetration. At the same time, the inverted conical discharge head 65 ensures that the seeds or fertilizer fall precisely into the target depth along the furrow formed by the furrowing teeth 56, avoiding nutrient volatilization or loss caused by shallow spreading. The cooperation between the guide box 63 and the discharge support 62 optimizes material flow and reduces the risk of blockage by straw or soil impurities.
[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
