[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example 1 To address the technical problems in the background section, the following seeder structure is proposed: Combination Figure 1-7 As shown, the present invention provides a seeder structure including a front support 14. A fertilizer box 2 is installed on the top surface of the front support 14. A plurality of fertilizer spreading boxes 21 are evenly and fixedly installed through the bottom surface of the fertilizer box 2. A plurality of front cover plates 1 are evenly and hinged to the top surface of the fertilizer box 2. A plurality of rear cover plates 9 are evenly and hinged to the top surface of the seed box 10. A pair of inclined fertilizer spreading plates 25 are provided below the plurality of fertilizer spreading boxes 21. Each fertilizer spreading plate 25 is fixedly connected to the front support 14. A suspension gantry 7 is provided between the two fertilizer spreading plates 25. A connector 6 is installed on the suspension gantry 7 and is connected to the tractor. A rear support 13 is provided on one side of the front support 14. An adjustment connector is provided between the rear support 13 and the front support 14. A seed box 10 is installed on the top surface of the rear support 13. Several seed boxes 15 are evenly and fixedly installed on the bottom surface of the seed box 10. A drive connector is provided between the rear support 13 and the front support 14.

[0015] The drive assembly includes a side reduction gearbox 3 and a matching reduction gearbox 17. The side reduction gearbox 3 is mounted on the front bracket 14, and a matching motor 22 is fixedly installed on the inner side of the front bracket 14. The power output end of the matching motor 22 is connected to the side reduction gearbox 3. A rotary tiller shaft 8 is rotatably mounted between the front bracket 14. One end of the rotary tiller shaft 8 is connected to the side reduction gearbox 3 and driven by the side reduction gearbox 3. Several rotary tiller blades 5 are evenly fixed on the rotary tiller shaft 8. A gearbox 17 is mounted on a rear support 13. Two vibrating rollers 11 are rotatably mounted on the rear support 13. Each vibrating roller 11 has two stalk-building discs 12 fixedly fitted on it. A reinforcing plate 26 can be installed above the two stalk-building discs 12. The reinforcing plate 26 is connected to the rear support 13, and a spraying device 27 can be installed on the reinforcing plate 26. The spraying device 27 is used to perform spraying operations simultaneously during integrated sowing. Each vibrating roller 11 is rotatably mounted inside the rear support 13, and one end of each vibrating roller 11 is connected to and driven by the gearbox 17. A drive motor 20 is mounted on the rear support 13, and a wide-angle drive shaft 19 is omnidirectionally connected between the drive motor 20 and the gearbox 17.

[0016] A plurality of seeding trays 16 are evenly fixed on the rear support 13. The seeding trays 16 are located below a plurality of seeding boxes 15, and the seeding trays 16 and seeding boxes 15 are arranged alternately. Two mounting brackets are fixed on the side of the front support 14 away from the rear support 13, and each mounting bracket is equipped with a rake blade 4. Two furrowing plows 18 are fixed on the side of the rear support 13 near the front support 14.

[0017] Working principle: The device is connected to a tractor. When the tractor moves forward and rotary tillage and ditching operations are required, the cooperating motor 22 is started. The power output end of the cooperating motor 22 drives the internal components of the side reduction gearbox 3 to rotate, which in turn drives the rotary tiller shaft 8 connected to it to rotate. Several rotary tiller blades 5, which are evenly fixed on the rotary tiller shaft 8, rotate at high speed with the shaft, performing rotary tillage and breaking up of the soil, creating suitable soil conditions for subsequent sowing. While the rotary tillage operation is being carried out simultaneously, the fertilizer in the fertilizer box 2 falls onto the surface of the rotary-tilled soil at a stable rate through several fertilizer spreading boxes 21 that are evenly inserted through the bottom surface, achieving synchronization of "rotary tillage-fertilization". Seeds in the seed box 10 fall through the seeding box 15 at the bottom and are then evenly dispersed into the soil through the staggered seeding trays 16 located below the seeding box 15, avoiding seed accumulation and ensuring uniform sowing density. When rotary tillage, fertilization, and sowing are carried out, the drive motor 20 can be started simultaneously. The drive motor 20 drives the wide-angle drive shaft 19 to rotate, and the wide-angle drive shaft 19 transmits power to the gearbox 17, which drives its internal components to rotate, ultimately driving the two vibrating rollers 11 to rotate. During the rolling process, the vibrating rollers 11 flatten the soil after sowing and simultaneously cover the seeds with soil, completing the entire sowing operation process.

[0018] Example 2 like Figure 1-7 As shown, based on the above embodiments, this embodiment further provides the following: The adjusting link includes several hinged frames 24 and several telescopic cylinders 23. The two ends of each hinged frame 24 are respectively movably hinged between the front support 14 and the rear support 13, and the two ends of each telescopic cylinder 23 are respectively movably hinged on the front support 14 and the rear support 13.

[0019] In practical use, based on Embodiment 1, if it is necessary to further enhance the practicality of the overall device, the operation is as follows: The front support 14 and the rear support 13 are movably hinged together by several hinged connecting frames 24, forming a rotatable connection structure. Simultaneously, both ends of each telescopic cylinder 23 are hinged to the front support 14 and the rear support 13 respectively. The telescopic cylinder 23 can output thrust or pull force through its telescopic movement. Based on the operation of Example 1, when it is necessary to adjust the height or angle of the covering part (vibrating roller 11 on the rear support 13, seeding tray 16, etc.) according to soil conditions (such as soil thickness, crop variety requirements for covering depth), the telescopic cylinder 23 is activated. If the soil covering depth needs to be increased, the telescopic cylinder 23 extends, pushing the rear support 13 to rotate downward around the hinge point of the hinged connecting frame 24, so that the vibrating roller 11 is closer to the ground, increasing the force of flattening the soil covering. If the soil covering depth needs to be reduced or to adapt to undulating ground, the telescopic cylinder 23 shortens, pulling the rear support 13 to rotate upward around the hinge point, so that the vibrating roller 11 maintains a suitable distance from the ground, avoiding excessive compaction of the soil. Through the flexible extension and retraction of the telescopic cylinder 23, the overall position of the rear support 13 can be precisely adjusted, thereby adapting to the sowing and soil covering needs under different operating scenarios.
