Description

Technical Field

[0001] This utility model relates to the field of cotton sowing technology, specifically to a precision cotton sowing device that prevents clogging. Background Technology

[0002] As is well known, in cotton cultivation, the efficiency and accuracy of the sowing process directly affect subsequent crop growth and yield. Traditional cotton seeders have many problems in use: on the one hand, the sowing interval is difficult to adjust flexibly according to planting needs, often requiring a fixed sowing density, which cannot adapt to different soil conditions and cotton varieties, resulting in uneven seed distribution and affecting crop growth space; on the other hand, seeds are prone to accumulation and blockage during storage and discharge, and seeds in the storage hopper often remain stuck due to poor flowability, which not only affects the continuity of sowing but also requires frequent manual cleaning, increasing labor intensity. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

A guide frame is provided on the installation shaft, and a discharge groove and a pusher plate are provided on the guide frame. An angle locking mechanism is provided between the threaded post and the adjustment box.

[0007] Furthermore, the present invention is improved in that the angle locking mechanism includes an annular tooth groove and a telescopic hole. The annular tooth groove is formed on the threaded hole, the telescopic hole is formed at one end of the threaded post, a slot is formed between the telescopic hole and the outer side of the threaded post, a polygonal post is provided on the telescopic hole, a tooth block is provided between the polygonal post and the slot, and the tooth block engages and abuts against one side of the annular tooth groove.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a clogging-resistant precision cotton seeder, which has the following beneficial effects:

[0015] This anti-clogging precision cotton seeder allows for switching between two different sowing intervals by selectively engaging the large and small gears on the shaft with the first and second gears on the mounting shaft. The operator simply rotates the threaded column, which moves the mounting shaft via the bearing housing, engaging either the first gear with the large gear or the second gear with the small gear. This changes the rotation speed of the mounting shaft and ultimately adjusts the sowing interval to meet the spacing requirements of different cotton varieties and planting conditions, improving planting adaptability. The design of the guide frame and pusher plate effectively solves the problem of seed accumulation and clogging. As the guide frame rotates at the bottom of the inner wall of the hopper, the pusher plate evenly pushes the seeds to the discharge trough, preventing seeds from accumulating in the hopper. Simultaneously, seeds are discharged when the discharge trough of the guide frame aligns with the discharge hole. The continuously rotating guide frame creates an orderly discharge rhythm, significantly reducing the risk of clogging, ensuring continuous sowing operations, and minimizing the need for manual cleaning.

[0021] 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.

[0022] Please see Figures 1-4This utility model relates to a precision cotton seeder designed to prevent clogging. It includes a seeder frame 1 and a roller 2. The seeder frame 1 has an adjustment box 3 at its top, and a storage hopper 4 on the adjustment box 3. The storage hopper 4 extends into the adjustment box 3. A discharge hole 9 is provided between the storage hopper 4 and the bottom of the seeder frame 1. A soil-turning mechanism is provided at the bottom of the seeder frame 1. An adjustment shaft 5 is provided on one side of the adjustment box 3, and an adjustment groove is provided inside the adjustment box 3. A large gear 6 and a small gear 7 are provided on the adjustment shaft 5 and located in the adjustment groove. A sprocket mechanism 8 is provided between the adjustment shaft 5 and the roller 2. A threaded hole is provided on the other side of the adjustment box 3, and a threaded post 10 is provided in the threaded hole. A discharge hole 9 is provided on the storage hopper 4. A through hole is provided, on which a mounting shaft 11 is provided. One end of the mounting shaft 11 extends into the adjusting groove. One end of the mounting shaft 11 is provided with a first gear 12 and a second gear 13. The other end of the mounting shaft 11 is provided with a bearing seat 14 between it and the threaded column 10. A guide frame 24 is provided on the mounting shaft 11. The guide frame 24 is provided with a discharge groove 15 and a pusher plate 16. An angle locking mechanism is provided between the threaded column 10 and the adjusting box 3. In this embodiment, a storage hopper 4 is provided at the top of the adjusting box 3, which extends into the adjusting box 3 for storing cotton seeds. The seeding frame 1 is assembled at the rear of the tractor in a conventional manner. The tractor tows this structure, and the rollers 2 roll on the ground. The sprocket mechanism 8 drives the adjusting shaft 5 to rotate. Personnel can select the appropriate interval based on the cotton planting needs: the first gear 12 meshes with the large gear 6, or the second gear 13 meshes with the small gear 7, thus achieving two different seed sowing intervals. Rotating the threaded column 10 moves it within the threaded hole, which in turn moves the mounting shaft 11 via the bearing seat 14. This causes the first gear 12 on the mounting shaft 11 to mesh with the large gear 6, or the second gear 13 to mesh with the small gear 7. The large gear 6 drives the first gear 12 to rotate, or the small gear 7 drives the second gear 13 to rotate, thereby adjusting the rotational speed of the mounting shaft 11. The mounting shaft 11 then causes the guide frame 24 to rotate at an angle at the bottom of the inner wall of the storage hopper 4, thus adjusting the cotton seed sowing interval. Seeds accumulate in the guide frame 24 by weight. When the discharge trough 15 of the guide frame 24 aligns with the discharge hole 9, the seeds are discharged. The continuously rotating guide frame 24 enables automatic sowing. The guide frame 24 and pusher plate 16 prevent seeds from accumulating in the storage hopper 4 and causing blockages. An angle locking mechanism locks the angle of the threaded post 10, preventing it from shifting during sowing and affecting the meshing stability between the first gear 12 and the large gear 6, or between the second gear 13 and the small gear 7. When sowing is not needed, rotating the threaded post 10 passes the second gear 13 through the small gear 7, thus misaligning the discharge trough 15 of the storage frame with the discharge hole and blocking the discharge hole with the storage frame, preventing seed discharge.For ease of future use, adjusting the threaded column 10 changes the position of the guide frame 24, thereby adjusting the output. The angle locking mechanism fixes the angle of the threaded column 10, ensuring stable output during sowing. The storage hopper 4, adjusting box 3, and related components work together to achieve orderly storage and precise dispensing of cotton seeds, reducing the risk of clogging.

[0023] To facilitate locking the angle of the threaded post 10, in this design, the angle locking mechanism includes an annular toothed groove 17 and a telescopic hole. The annular toothed groove 17 is formed on the threaded hole, and the telescopic hole is formed at one end of the threaded post 10. A slot is formed between the telescopic hole and the outer side of the threaded post 10. A polygonal post 18 is provided on the telescopic hole, and a toothed block 19 is provided between the polygonal post 18 and the slot. The toothed block 19 engages with one side of the annular toothed groove 17. By pushing the polygonal post 18, the toothed block 19 can be disengaged from the annular toothed groove 17, thereby rotating the threaded post 10. When it is necessary to lock the threaded post 10, pulling the polygonal post 18 will cause the toothed block 19 to move linearly through the slot and engage with the annular toothed groove 17, thereby locking the angle of the threaded post 10.

[0024] To facilitate soil loosening, the soil-tilling mechanism in this design includes a soil-tilling shovel 20 and a mounting column 21. The mounting column 21 is installed at the bottom of the sowing frame 1, and a material guide hole 22 is provided at the bottom of the mounting column 21. The material guide hole 22 is located below the discharge hole 9. The soil-tilling shovel 20 is installed at the bottom of the mounting column 21. Before sowing, the soil-tilling shovel 20 can loosen the soil to create favorable conditions for sowing, and the material guide hole 22 can guide the seeds to fall smoothly into the loosened soil, improving the sowing quality.

[0025] To further prevent seed blockage, in this solution, multiple pusher plates 16 are arranged in a circular array. Multiple pusher plates 16 can push seeds from the storage hopper 4 to the discharge trough 15 more efficiently, improving sowing efficiency and reducing the possibility of seeds accumulating in the guide frame 24 and causing blockage.

[0026] To reduce dust entering the storage hopper 4, in this design, the top of the storage hopper 4 is provided with a sealing cover 23. The sealing cover 23 is snapped into the storage hopper 4. The sealing cover 23 can prevent external dust and debris from entering the storage hopper 4, avoid contaminating the seeds, ensure seed quality, and prevent the seeds from getting damp, which is beneficial for long-term storage.

[0027] To improve the smooth linear movement of the polygonal column 18, in this design, the polygonal column 18 has a hexagonal structure that is adapted to the telescopic hole. The hexagonal structure can better cooperate with the telescopic hole, making the polygonal column 18 more accurately positioned within the telescopic hole, ensuring stable engagement between the toothed block 19 and the annular toothed groove 17, and improving the reliability of the angle locking mechanism.

[0028] To improve the stability of the toothed block 19 when it meshes with the annular toothed groove 17, in this design, the inner wall of the telescopic hole is provided with a rubber pad. The rubber pad can increase the friction between the polygonal column 18 and the telescopic hole, making its positioning more stable, while reducing the noise generated by the polygonal column 18 shaking in the telescopic hole, buffering vibration, and protecting the components of the angle locking mechanism.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
