[0047] An adjustment structure, mounted on the first shaft 6, for adjusting the space size of the tank 5;

[0048] The slotted structure is provided with multiple groups, and all of them are installed on one side of the connecting frame 1, such as Figure 2 and Figure 3 As shown, the discharge port 302 is connected to the slotted structure through the guide pipe 7;

[0049] The capillary tube laying structure is installed on one side of the connecting frame 1, and the capillary tube laying structure is located between two adjacent slotted structures;

[0050] The roller 8 is rotatably connected to both sides of the connecting frame 1, and the first shaft 6 is connected to the roller 8 through a linkage structure, specifically: Figure 1 As shown, the linkage structure includes a driving gear plate 33 and a driven gear plate 34, and the two sides of the connecting frame 1 are rotatably connected to a second shaft rod 35, and the roller 8 is fixedly connected to the second shaft rod 35;

[0051] The driving sprocket 33 is fixedly connected to one of the second shafts 35 , and the driven sprocket 34 is fixedly connected to the first shaft 6 . The driving sprocket 33 and the driven sprocket 34 are meshed with the same chain 36 .

[0052] The connecting frame 1 is connected to a driving vehicle (not shown in the figure), and the connecting frame 1 is driven by the driving vehicle to move. The roller 8 rolls forward to drive the active gear plate 33 to rotate through the second shaft 35, and the active gear plate 33 drives the driven gear plate 34 to rotate through the chain 36, so that the rotating teeth 4 on the first shaft 6 rotate, and the seeds in the seed storage frame 2 flow into the trough body 5 through the feed port 301. As the rotating teeth 4 rotate, the trough body 5 is connected with the discharge port 302, so that the seeds are discharged into the guide pipe 7 through the discharge port 302;

[0053] Further, such as Figure 3-Figure 6 As shown, the adjustment structure includes a spacer ring 9, a spacer ring receiving roller 10 and a side cover 11. The spacer ring 9 is plugged into the rotating gear 4. The number of the spacer ring 9 is at least one. The tank body 5 is divided into a plurality of chambers 12 by the spacer ring 9.

[0054] The spacer ring receiving roller 10 is fixedly mounted on the first shaft 6, and one end of the spacer ring receiving roller 10 is in contact with the rotating gear 4. The spacer ring receiving roller 10 is provided with a pair of slots 13, and the pair of slots 13 correspond to the spacer rings 9 one by one, and one side of the spacer ring 9 is connected to the corresponding pair of slots 13;

[0055] The spacer ring receiving roller 10 is provided with a push groove 14, which is connected to the insertion slot 13. The side cover 11 is slidably connected to the first shaft 6, and one end of the side cover 11 is in contact with the other end of the rotating tooth 4. The spacer ring receiving roller 10 and the side cover 11 can block the two ends of the trough body 5 to prevent seeds from leaking out.

[0056] The side cover 11 and the first shaft 6 are clamped with a same latch pin 15 , and both ends of the latch pin 15 are sleeved with rubber sleeves 16 , which can prevent the latch pin 15 from falling off.

[0057] When the space of the slot body 5 needs to be expanded, the rubber sleeve 16 at one end of the latch 15 is taken out, and the latch 15 is pulled out, thereby canceling the fixation between the side cover 11 and the first shaft 6, pulling out the side cover 11, and pushing the spacer ring 9 outwards. At this time, the spacer ring 9 will be pushed into the corresponding slot 13 for storage. In the process of pushing the spacer ring 9 outwards, the push slot 14 can also be used for auxiliary dragging to increase the adjustment speed;

[0058] When the space of the trough body 5 needs to be reduced, the spacer ring 9 can be pushed back onto the rotating tooth 4 through the push groove 14. When in use, the space of the trough body 5 can be adjusted according to the particle size of the seeds to improve the adaptability to the seeds.

[0059] Further, such as Figure 7 and Figure 8 As shown, a U-shaped card plate 17 is installed on one side of the connecting frame 1, and a connecting piece 18 is rotatably connected to the U-shaped card plate 17. The slotting structure includes a first scraper plate 19, and the top of the first scraper plate 19 is fixedly connected to the connecting piece 18. A slot for sowing seeds can be opened on the ground where planting is required through the first scraper plate 19. A positioning tube 20 is fixedly connected to one side of the connecting piece 18, and the free end of the guide tube 7 is inserted into the positioning tube 20;

[0060] The first scraper plate 19 is provided with a seed guide groove 21, and the bottom of the positioning tube 20 is connected to the seed guide groove 21. The seeds are discharged into the guide tube 7 through the discharge port 302, and fall into the groove pit through the positioning tube 20 and the seed guide groove 21. The seed guide groove 21 is provided to ensure that the seeds can fall into the groove pit according to a predetermined path;

[0061] Furthermore, a U-shaped support plate 22 is fixedly connected to the U-shaped clamping plate 17, and the connecting piece 18 is located between the U-shaped support plates 22. A spring support rod 23 is fixedly connected to the top of the U-shaped support plate 22. A spring retaining ring 24 is provided on the outer periphery of the U-shaped support plate 22. The bottom of the spring retaining ring 24 abuts against the connecting piece 18, and a conical spring 25 is clamped on the top. A nut 26 is threadedly connected to the top of the spring support rod 23, and the top of the conical spring 25 abuts against the bottom of the nut 26. When the nut 26 is screwed, the nut 26 moves downward along the spring support rod 23 and squeezes the conical spring 25. At this time, the conical spring 25 is in a compressed state and applies a downward pressure to the connecting piece 18 through the spring retaining ring 24, so that the first scraper plate 19 can move smoothly. At the same time, the conical spring 25 provides elastic buffering for the first scraper plate 19. When encountering stones or other obstacles, the first scraper plate 19 will tilt up to avoid damage to the first scraper plate 19 caused by hard contact.

[0062] Further, such as Figure 2 and Fig. 9 As shown, the capillary tube laying structure includes a second scraper plate 27 and a pressure wheel 28. The second scraper plate 27 is fixedly connected to one side of the connecting frame 1. The pressure wheel 28 is detachably rotatably connected to one side of the second scraper plate 27. A hollow tube 29 is fixedly connected to one side of the connecting frame 1. The hollow tube 29 is located directly above the second scraper plate 27. A limiting sleeve 30 is clamped on the top of the hollow tube 29. A drip irrigation tape roll 31 is detachably installed on one side of the connecting frame 1, and the drip irrigation tape roll 31 is located above the limiting sleeve 30.

[0063] The drip irrigation belt can be limited by the setting of the limiting sleeve 30. The limiting sleeve 30 is provided with a circular tube limiting groove 3001 and a flat tube limiting groove 3002. The circular tube limiting groove 3001 is connected with the hollow tube 29. Common drip irrigation belts include flat drip irrigation belts and circular drip irrigation belts. When assembling, the corresponding limiting groove can be selected according to the style of the drip irrigation belt for limiting to avoid the drip irrigation belt from being entangled.

[0064] Before work, the drip irrigation tape is pulled out and passed through the hollow tube 29, and passed out from the bottom of the pressure wheel 28, and the end is fixed to the ground. When the second scraper blade 27 moves forward, a groove for laying the drip irrigation tape will be opened on the ground, and the pressure wheel 28 will be driven to roll forward at the same time. When the pressure wheel 28 rolls forward, it will squeeze the drip irrigation tape, causing the drip irrigation tape roll 31 to release the drip irrigation tape. As the pressure wheel 28 continues to roll and squeeze forward, the drip irrigation tape will be laid in the groove opened by the second scraper blade 27.

[0065] Embodiment 2

[0066] like Figure 1-Figure 9As shown, this embodiment is improved on the basis of the first embodiment as follows: further, the two first scraper boards 19 located at the edge are hung with the same chain 32, and when the first scraper board 19 moves forward, the chain 32 will drag on the ground, thereby gathering the soil on both sides of the first scraper board 19 and the second scraper board 27 to the middle, and covering the seeds and the drip irrigation belt with soil.

[0067] In summary, the workflow of the utility model is:

[0068] Before work, connect the connecting frame 1 to the driving vehicle, pull out the drip irrigation belt and pass it through the hollow tube 29, and pass it out from the bottom of the pressure wheel 28, and fix the end to the ground;

[0069] The connecting frame 1 is driven forward by the driving vehicle.

[0070] When the first scraper plate 19 moves forward, a groove pit for sowing seeds will be opened on the ground; the roller 8 will roll forward and drive the active gear plate 33 to rotate through the second shaft rod 35, and the active gear plate 33 will drive the driven gear plate 34 to rotate through the chain 36, so that the rotating teeth 4 on the first shaft rod 6 will rotate, and the seeds in the seed storage frame 2 will flow into the trough body 5 through the feed port 301. As the rotating teeth 4 rotate, the trough body 5 is connected with the discharge port 302, so that the seeds are discharged into the guide pipe 7 through the discharge port 302, and fall into the groove pit through the positioning pipe 20 and the seed guide groove 21.

[0071] When the second scraper blade 27 moves forward, a groove for laying the drip irrigation tape will be opened on the ground, and at the same time, the pressure wheel 28 will be driven to roll forward. When the pressure wheel 28 rolls forward, it will squeeze the drip irrigation tape, causing the drip irrigation tape roll 31 to release the drip irrigation tape. As the pressure wheel 28 continues to roll and squeeze forward, the drip irrigation tape will be laid in the groove opened by the second scraper blade 27.

[0072] When the first scraper blade 19 moves forward, the chain 32 will drag on the ground, thereby gathering the soil on both sides of the first scraper blade 19 and the second scraper blade 27 to the middle, and covering the seeds and the drip irrigation belt with soil.

[0073] The above different embodiments can be combined, replaced and used in conjunction with each other.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
