Abstract
Description
Technical Field
[0001] This utility model relates to the field of cotton seeding machine technology, specifically to an adjustable cotton dry-seeding and wet-exit seeding machine. Background Technology
[0002] Dry-seeding and wet-emergence cotton cultivation is a suitable method for arid or semi-arid regions. Its main characteristic is that before sowing, there is no winter or spring irrigation. Instead, after land preparation, drip irrigation tape and mulch are laid, followed by cotton seed sowing and covering with soil. Once the suitable emergence temperature is reached, small amounts of water are dripped under the mulch to ensure the soil moisture reaches the level required for cotton seed emergence. This technique effectively improves water resource utilization efficiency and promotes early crop growth.
[0003] When dry-sowing and wet-laying cotton, drip irrigation tape and mulch film must be laid simultaneously. If the sowing spacing needs to be adjusted, the spacing of the drip irrigation tape must also be adjusted accordingly. However, the drip irrigation tape cannot be easily adjusted, resulting in an unstable spacing between the seeds and the drip irrigation tape. This causes some seeds to be unable to absorb water effectively after sowing, affecting the germination rate. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable cotton dry-seeding and wet-laying seeder to solve the problem mentioned in the background art that the drip irrigation belt cannot be easily adjusted when cotton is dry-seeding and wet-laying, resulting in an unstable distance between the seeds and the drip irrigation belt, which makes it impossible for some seeds to absorb water effectively after sowing, thus affecting the germination rate.

A U-shaped positioning component is fixed on the frame between the limiting seats, and a second double-helix adjusting screw passes through the U-shaped positioning component and the limiting seat. A limiting rod passing through the limiting seat is also provided between the U-shaped positioning component and the frame, so that the second double-helix adjusting screw can rotate, enabling the limiting seats to move relative to each other. Main rollers are symmetrically installed on the other side of the bottom of the frame, and a connecting frame is also connected to the bottom of the frame on that side. A soil scraper and a soil pressing limiting roller are installed at the lower end of the connecting frame. A drip irrigation tape mounting frame and a mulch film positioning frame are provided at the upper end of the frame, and a fixing frame is provided below the frame. A drip irrigation tape positioning rod, a mulch film spreading roller, and a soil covering wheel are sequentially installed between the fixing frames.
[0006] Preferably, the drip irrigation tape positioning rod is located near the soil pressing and limiting roller, and positioning plates are also fixed to both ends of the drip irrigation tape positioning rod by welding.
[0007] Preferably, a first double-helix adjusting screw is rotatably connected between the positioning plates, and the reverse thread structure of the first double-helix adjusting screw is respectively engaged with the drip irrigation tape limiting seat.
[0008] Preferably, a drip irrigation tape limiting seat is movably sleeved on the drip irrigation tape positioning rod, and a groove is formed in the middle of the drip irrigation tape limiting seat to engage with the drip irrigation tape.
[0009] Preferably, a lifting cylinder is fixed to the upper end of the fixing frame by bolts, and the lifting cylinder is installed at the bottom of the vehicle frame by bolts.

A seed sowing mechanism is also installed on the sowing mechanism mounting frame above the fixed disc, and a sowing connecting pipe connects the seed sowing mechanism and the fixed disc.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This cotton dry-seeding and wet-exit adjustable seeder allows for convenient adjustment of the sowing spacing and can adjust the drip irrigation tape spacing according to the sowing spacing, ensuring that the seeds and drip irrigation tape are positioned in a corresponding manner. This ensures that the required humidity can be quickly reached after sowing, thereby guaranteeing the seed germination effect. This cotton dry-seeding and wet-exit adjustable seeder first levels the planting area, then lays the drip irrigation tape and mulch, and finally sows and covers the seeds with soil. The drip irrigation tape positioning structure can be assisted by a soil-pressing and limiting roller to ensure reliable positioning of the drip irrigation tape, thereby ensuring that the drip irrigation tape and seeds are positioned in a corresponding manner and guaranteeing the germination rate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-4This utility model provides a technical solution: a cotton dry-seeding and wet-exit adjustable seeder, including a cotton seeder body 1, a frame 2 on the cotton seeder body 1, and a U-shaped limiting seat 13 on one side of the frame 2. A seeding mechanism mounting frame 15 connected to the limiting seat 13 is provided at the end of the frame 2 on that side. A U-shaped positioning component 202 is fixed on the frame 2 between the limiting seats 13, and a second double-helix adjusting screw 1302 passes through both the U-shaped positioning component 202 and the limiting seat 13. A limiting rod 1301 passing through the limiting seat 13 is also provided between the U-shaped positioning component 202 and the frame 2, causing the second double-helix adjusting screw 1302 to rotate, thus enabling the mutual movement of the limiting seats 13. Symmetrically mounted on the other side of the bottom of the frame 2 are... The main roller 3 is connected to the bottom side of the frame 2, and a connecting frame 201 is also connected to it. A scraper 4 and a soil-pressing limiting roller 5 are installed at the lower end of the connecting frame 201. A drip irrigation tape mounting frame 7 and a plastic film positioning frame 11 are provided at the upper end of the frame 2. A fixed disc 16 is installed on the sowing mechanism mounting frame 15, and auxiliary rollers 1601 are rotatably mounted between the fixed discs 16. A seed sowing mechanism 14 is also installed on the sowing mechanism mounting frame 15 above the fixed discs 16, and a sowing connecting pipe 1401 connects the seed sowing mechanism 14 and the fixed discs 16. This structure of the sowing mechanism mounting frame 15 is an existing sowing mechanism for cotton seeds. The seed sowing mechanism 14 guides the seeds, thereby positioning them through the fixed discs 16 and the auxiliary rollers 1601. The device is designed with a sowing port that can be inserted into the mulch film, allowing seeds to be sown under the film. A fixing frame 9 is located below the frame 2, with a lifting cylinder 12 bolted to its upper end. The lifting cylinder 12 is bolted to the bottom of the frame 2. This structure allows the lifting cylinder 12 to adjust the height of the fixing frame 9 while the frame 2 is positioned, enabling efficient mulch film spreading. A drip irrigation tape positioning rod 6, a mulch film spreading roller 8, and a soil covering wheel 10 are sequentially installed between the fixing frames 9. The drip irrigation tape positioning rod 6 is located near the soil-pressing limiting roller 5, and positioning plates 603 are welded to both ends of the rod. This structure, through the cooperation of the soil-pressing limiting roller 5 and the scraper 4, can level uneven areas of the planting area and make the ground smooth. The drip irrigation tape is compacted for mulching. The drip irrigation tape positioning rod 6 can cooperate with the soil compaction limiting roller 5, allowing the soil compaction limiting roller 5 to simultaneously compact the soil and stabilize the drip irrigation tape, ensuring the accuracy of the drip irrigation tape's laying position. A drip irrigation tape limiting seat 601 is movably sleeved on the drip irrigation tape positioning rod 6, and a groove is formed in the center of the drip irrigation tape to engage with it. This structure allows the drip irrigation tape limiting seat 601 to limit the drip irrigation tape through the groove. At the same time, the drip irrigation tape limiting seat 601 can move on the drip irrigation tape positioning rod 6. By adjusting the position of the drip irrigation tape limiting seat 601, the drip irrigation tape can be adjusted according to the sowing spacing. A first double-helix adjusting screw 602 is rotatably connected between the positioning plates 603.Furthermore, the reverse thread structure of the first double-helix adjusting screw 602 is respectively engaged with the drip irrigation tape limiting seat 601. This structure allows the first double-helix adjusting screw 602 to rotate under the positioning of the positioning plate 603, thereby adjusting the position of the drip irrigation tape limiting seat 601. Simultaneously, the groove portion of the drip irrigation tape limiting seat 601 is not obstructed by the first double-helix adjusting screw 602, ensuring the limiting function of the drip irrigation tape limiting seat 601.
[0019] Working Principle: When using this cotton dry-seeding and wet-laying adjustable seeder, the main body 1 of the cotton seeder is first connected to the drive structure via the frame 2 for movement of the main body 1 in the planting area. Cotton seeds are placed in the seed sowing mechanism 14. The drip irrigation tape and mulch film are respectively installed on the drip irrigation tape mounting frame 7 and the mulch film positioning frame 11. The position of the seed sowing mechanism 14 is adjusted according to the required sowing spacing. The second double-helix adjusting screw 1302 is rotated by the gear structure in the middle of the second double-helix adjusting screw 1302, causing the limiting seat 13 to move relative to the frame 2 under the limitation of the limiting rod 1301. The limiting seats 13 move closer or further apart from each other, adjusting the position of the sowing mechanism mounting frame 15. The U-shaped positioning part 202 is used for the installation and positioning of the middle adjustment part of the second double-helix adjusting screw 1302. Then, the spacing of the drip irrigation tape limiting seats 601 on the drip irrigation tape positioning rod 6 is adjusted, allowing the first double-helix adjusting screw 602 to rotate under the positioning plate 603, adjusting the drip irrigation... After the drip irrigation tape and mulch film are positioned on the drip irrigation tape positioning rod 6 with the limit seat 601 in place, the main body 1 of the cotton planter is started. The main body 1 of the cotton planter moves with the cooperation of the main roller 3 and the auxiliary roller 1601. The scraper 4 is located at the forward end and scrapes the surface of the planting area to make it flat. The soil is then pressed down by the soil pressing limit roller 5. The fixed frame 9 moves to the appropriate position under the drive of the lifting cylinder 12. At this time, the groove part of the drip irrigation tape limit seat 601 cooperates with the soil pressing limit roller 5 to press the drip irrigation tape into place. The irrigation tape is reliably positioned to ensure accurate placement. The mulch film spreading roller 8 spreads the mulch film and stabilizes the drip irrigation tape. The connecting frame 201 reliably positions the scraper 4 and the soil pressing and limiting roller 5. After the mulch film is spread, the soil covering wheel 10 covers the soil to the edge of the mulch film during movement to fix it. The seed sowing mechanism 14 is connected to the fixed disc 16 through the sowing connecting pipe 1401 to achieve synchronous sowing during movement, thus completing a series of tasks.
