[0025] Specifically, when the hydraulic cylinder 2 drives the support plate 3 to move, it has the effect of adjusting the height of the flat ground adjusting rod 8 and the flat ground block 9. The limiting block 4 slides inside the inner wall of the connecting block 1 to achieve the first limiting effect. By driving the first connecting rod 5 and the second connecting rod 7 through the connecting block 1 and driving the support plate 3 and the flat ground adjusting rod 8 through the limiting effect of the limiting plate 6, it not only achieves the multiple limiting effect of adjusting the height of the flat ground adjusting rod 8, but also has the height for adjusting the flat ground block 9, so that the soil can better cover the seeds after the grooving shovel 11 digs a groove during use, improving the survival rate.

[0026] Referring to Figure 3 and Figure 4 , the inner wall of the first rotating roller 13 is rotatably connected to the outer wall of the first rotating shaft 10. The inner wall of the second rotating roller 15 is fixedly connected to the second rotating shaft 16. The outer wall of the second rotating shaft 16 is fixedly connected to the sowing wheel 17. The outer wall of the sowing wheel 17 is rotatably connected to the seed storage box 18. The outer wall of the seed storage box 18 is fixedly connected to the outer wall of the first rotating shaft 10; the outer wall of the seed storage box 18 is fixedly connected to the electric slide rail 19, and the outer wall of the electric slide rail 19 is provided with an electric slider 20; the outer wall of the electric slider 20 is slidably connected to the mounting shell 21, and the outer wall of the mounting shell 21 is fixedly connected to the motor 22;

[0027] Specifically, by driving the second rotating roller 15 to drive the second rotating shaft 16 and the sowing wheel 17 to rotate inside the seed storage box 18, through the rolling effect of the roller 12, the seeds can be quickly sown after the grooving shovel 11 breaks the soil surface. Through the electric slider 20 and the electric slide rail 19, the seeds inside the seed storage box 18 can be flattened to prevent accumulation.

[0028] Referring to Figure 4 , the output end of the motor 22 is fixedly connected to the gear 23, and the outer wall of the gear 23 is meshed with the rack 24; the outer wall of the rack 24 is slidably connected to the inner wall of the mounting shell 21, and the outer wall of the rack 24 is fixedly connected to the clamping rod 25; the outer wall of the clamping rod 25 is slidably connected to the outer wall of the electric slider 20, and the lower surface of the mounting shell 21 is fixedly connected to the scraping plate 26, and the outer wall of the scraping plate 26 is slidably connected to the inner wall of the seed storage box 18;

[0029] Specifically, by driving the motor 22 to drive the gear 23 to rotate, by driving the rack 24 to slide inside the mounting shell 21 through the gear 23, and by driving the clamping rod 25 through the rack 24, the scraping plate 26 can be quickly fixed to the outer wall of the electric slider 20. During use, the scraping plate 26 can be quickly fixed and disassembled, facilitating replacement when damaged.

[0030] Working principle: When the device needs to be used, during the use process, the hydraulic cylinder 2 drives the support plate 3 to move, which has the effect of adjusting the height of the flat ground adjusting rod 8 and the flat ground block 9. During the use process, the limiting block 4 slides on the inner wall of the connecting block 1 to achieve the first limiting effect. The connecting block 1 drives the first connecting rod 5 and the second connecting rod 7. Through the limiting of the limiting plate 6, the support plate 3 and the flat ground adjusting rod 8 can, during the use process, not only achieve multiple limiting effects on the height adjustment of the flat ground adjusting rod 8, but also have the height for adjusting the flat ground block 9. Thus, during the use process, after the grooving shovel 11 digs a groove, the soil can better cover the seeds, improving the survival rate. During the use process, the motor 22 drives the gear 23 to rotate. The gear 23 drives the rack 24 to slide on the inner wall of the installation shell 21. The rack 24 drives the clamping rod 25 to quickly fix the scraper 26 on the outer wall of the electric slider 20. And through the electric slider 20 sliding on the outer wall of the electric slide rail 19, the seeds can be evenly loaded into the seed storage box 18 for sowing. During the use process, when the roller 12 rotates on the outer wall of the first rotating shaft 10, the grooving shovel 11 breaks the soil. The roller 12 drives the first rotating roller 13 and the belt 14 to drive the second rotating roller 15. Thus, the second rotating roller 15 drives the second rotating shaft 16 and the sowing wheel 17 to rotate. The sowing wheel 17 sows the seeds into the soil broken by the grooving shovel 11. During the use process, sowing can be carried out evenly, reducing the waste of excess seeds. When this seeder is in use, not only does it achieve that when the hydraulic cylinder 2 drives the support plate 3 to move, the limiting block 4 slides on the inner wall of the connecting block 1, driving the first connecting rod 5 and the second connecting rod 7, and through the limiting of the limiting plate 6, the support plate 3 and the flat ground adjusting rod 8 can adjust the height of the flat ground block 9 during the use process. Thus, during the use process, after the grooving shovel 11 digs a groove, the soil can better cover the seeds, improving the survival rate, but also has the effect that through the electric slider 20 sliding on the outer wall of the electric slide rail 19, the seeds can be evenly loaded into the seed storage box 18 for sowing.
