[0002] A wheat seeder is a mechanical device that plants wheat seeds in the soil through a sowing mechanism. Typically driven by a tractor and equipped with a fertilizer spreader, this machine is suitable for fertilizing and sowing wheat in both plains and hilly areas. It boasts excellent general performance, a wide range of adaptability, and uniform sowing. Current wheat seeders are typically equipped with a depth adjustment mechanism that adjusts the sowing depth based on soil conditions and sowing requirements.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0020] The utility model provides a technical solution: Figure 1 and Figure 4 As shown, in this embodiment, a wheat sowing depth adjustment mechanism includes a seeder seat 1, two sowing boxes 3 are fixedly connected to the top of the seeder seat 1, and a dividing plate 5 is rotatably connected in the sowing box 3. Two discharge pipes 6 are connected to the bottom of the seeder seat 1, and a feed funnel 4 is fixedly connected to one side of the sowing box 3. An adjusting structure 7 is provided in the seeder seat 1, a moving cylinder 9 is slidably connected in the discharge pipe 6, and a limiting structure 8 is connected to the outside of the moving cylinder 9. The adjusting structure 7 is connected to the limiting structure 8, a slide groove 12 is provided in the discharge pipe 6, and the limiting structure 8 is slidably connected in the slide groove 12. A conical cylinder 11 is connected above the moving cylinder 9, and the adjusting structure 7 includes an L-shaped plate 701, a threaded rod 702, a plow 703 and a connecting plate 706. A fixed plate 705 is connected in the plow 703, and a motor 704 is connected above the L-shaped plate 701. The threaded rod 702 is rotatably connected in the seeder seat 1, and the plow 703 is threadedly connected to the outside of the L-shaped plate 701.
[0021] like Figure 1 and Figure 3 As shown, a roller 2 is rotatably connected inside the seed drill seat 1, a pressure plate 10 is fixedly connected to the left side below the seed drill seat 1, an L-shaped plate 701 is fixedly connected to the top of the seed drill seat 1, the output shaft of the motor 704 is connected to the threaded rod 702, the plow 703 is slidably connected inside the seed drill seat 1, and the bottom of the fixed plate 705 is connected to the top of the connecting plate 706.
[0022] By setting the fixed plate 705 and the connecting plate 706, when the threaded rod 702 rotates, the plow 703 will move on its surface. Since the fixed plate 705 inside the plow 703 is connected to the plow 703, the connecting plate 706 and the plow 703 move synchronously at the same time, so that the sowing depth and the digging depth can be adjusted at the same time, maintaining the consistency and accuracy of sowing, and ensuring the versatility and flexibility of the machine.
[0023] like Figure 4As shown, the limiting structure 8 includes a protrusion 801 and a fixed column 802. The protrusion 801 is fixedly connected to the outer surface of the movable cylinder 9. The protrusion 801 is connected to the connecting plate 706. The fixed column 802 is fixedly connected above the protrusion 801. A fixed plate 803 is fixedly connected above the fixed column 802. The fixed plate 803 is slidably connected in the slide groove 12. A spring 804 is connected to the outer shell of the fixed column 802. The fixed plate 803 is connected to the slide groove 12 through the spring 804. The fixed column 802 is slidably connected in the slide groove 12.
[0024] By setting the slide groove 12 and the spring 804, the protrusion 801 on the surface of the movable cylinder 9 will drive the fixed column 802 and the fixed plate 803 to slide in the slide groove 12 when the movable cylinder 9 moves, and the fixed plate 803 will drive the spring 804 to deform when it moves, so that the slide groove 12 plays a certain guiding role in the movement of the movable cylinder 9, avoiding the movable cylinder 9 from getting stuck when moving, and the spring 804 plays a certain positioning role on the movable cylinder 9, avoiding the movable cylinder 9 from getting separated when moving.
[0025] The utility model provides a wheat sowing depth adjustment mechanism, the specific working principle of which is as follows:
[0026] When wheat sowing is being carried out, the seed drill seat 1 and the roller 2 can be used to move in the planting area, and then the wheat seeds can be placed in the feed funnel 4. After the seeds fall naturally, they will be transported one by one through the distribution plate 5, and then the seeds will be transported to the discharge pipe 6. When the adjusting structure 7 is in use, the motor 704 drives the threaded rod 702 to rotate, and the plow 703 moves on the surface of the threaded rod 702. Since the fixed plate 705 in the plow 703 is connected to the plow 703, the connecting plate 706 and the plow 703 move synchronously, and the connecting plate 706 drives the moving cylinder 9 to slide in the discharge pipe 6. When the moving cylinder 9 moves, the protrusion 801 on the surface drives the fixed column 802 and the fixed plate 803 to slide in the slide groove 12. When the fixed plate 803 moves, it drives the spring 804 to deform, and then the plow 703 is used to dig the planting area. After sowing is completed, the soil in the area is restored by the pressing plate 10.
[0027] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
