[0002] Corn is one of the most important food crops, widely used in cooking, food processing, animal feed, and industrial fields. Therefore, the importance of corn planting is self-evident. Scientific planting techniques and management can increase land yields and maintain the ecological environment, thereby improving agricultural production efficiency and economic benefits. Corn planting refers to the process of scattering corn seeds on the land within a cultivated area using appropriate planting techniques, cultivating the land, and then waiting for harvest. During planting, attention must be paid to a series of factors such as site selection, planting distance, and fertilization to ensure the ecological environment and quality of the corn. Planting equipment is required for corn planting.

[0003] Existing corn planting devices typically use a fixed plow to create a furrow in the field, then sow corn seeds into the furrow. However, the position of the plow cannot be adjusted, making it impossible to create furrows at a suitable planting depth based on soil conditions. This results in difficulty controlling the planting depth, poor applicability, and inconvenience. Therefore, we propose a planting device with controllable planting depth. Utility Model Content

[0033] 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.

[0034] Please see Figures 1 to 6 This utility model provides a technical solution:

[0035] A seeding device with controllable planting depth includes a mounting plate 1, a placement box 2 fixedly connected to the top of the mounting plate 1, a placement groove 24 opened inside the placement box 2, a connecting shaft 23 rotatably connected inside the placement box 2 and below the placement groove 24, a seeding seat 21 fixedly connected to the outside of the connecting shaft 23, a seeding groove 22 equidistantly opened inside the seeding seat 21, a limiting slide rod 43 equidistantly slidably connected inside the mounting plate 1, a connecting frame 4 fixedly connected to one end of the limiting slide rod 43, a plow head 42 fixedly connected to the bottom of the connecting frame 4, a threaded rod 41 threadedly connected inside the mounting plate 1, the threaded rod 41 rotatably connected to the connecting frame 4, and an adjusting handwheel 44 fixedly connected to the end of the threaded rod 41 away from the connecting frame 4.

[0036] In this design, corn seeds can be placed in the placement box 2 and placement trough 24. The connecting shaft 23 drives the sowing seat 21 to rotate, thereby scattering the corn seeds that have fallen into the sowing trough 22 for sowing in sequence, resulting in a more uniform sowing effect. The handwheel 44 is adjusted to drive the threaded rod 41 to rotate, and the rotation of the threaded rod 41 drives the connecting frame 4 to move. The limiting slide rod 43 can limit the movement of the connecting frame 4 to prevent it from deviating during movement. The connecting frame 4 drives the plow head 42 to move, thereby adjusting the height of the plow head 42 during use, which can cultivate furrows suitable for the sowing depth of corn seeds, making it convenient to control the planting depth.

[0037] like Figures 1 to 3As shown: In this scheme, a fixed frame 3 is fixedly connected to the outside of the placement box 2, and a drive shaft 33 is rotatably connected inside the fixed frame 3. A first gear 32 is fixedly connected to the outside of the drive shaft 33, and a second gear 34 that works with the first gear 32 is fixedly connected to the outside of the connecting shaft 23. The diameter of the second gear 34 is larger than the diameter of the first gear 32. A drive motor 31 is fixedly connected to the outside of the fixed frame 3, and the output end of the drive motor 31 is fixedly connected to the drive shaft 33.

[0038] In this scheme, the drive motor 31 facilitates the rotation of the drive shaft 33, which in turn drives the first gear 32 to rotate, which in turn drives the second gear 34 to rotate, thereby causing the connecting shaft 23 to rotate.

[0039] like Figure 4 As shown: In this scheme, a through groove 11 is provided inside the mounting plate 1 and below the seeding seat 21.

[0040] In this design, the through groove 11 allows the corn seeds that fall out of the seeding trough 22 to continue falling, thus facilitating the sowing of the corn seeds.

[0041] like Figure 5 and Figure 6 As shown: In this scheme, a connecting frame 5 is fixedly connected to the top of the mounting plate 1. A sliding block 54 is slidably connected inside the connecting frame 5. The sliding block 54 fits against the inner wall of the connecting frame 5. A locking tooth 55 is fixedly connected to one side of the sliding block 54. A limiting rack 45 that works with the locking tooth 55 is fixedly connected to the outer side of one of the limiting slide rods 43. A limiting groove 56 that works with the limiting slide rod 43 is opened inside the connecting frame 5. A connecting rod 51 is fixedly connected to one side of the sliding block 54. The connecting rod 51 is slidably connected to the connecting frame 5. A return spring 53 is sleeved on the outer side of the connecting rod 51 and on the side of the sliding block 54. A connecting block 52 is fixedly connected to the end of the connecting rod 51 away from the sliding block 54.

[0042] In this design, the connecting block 52 drives the connecting rod 51 to move, and the connecting rod 51 drives the sliding block 54 to slide. The reset spring 53 can drive the sliding block 54 to move and reset. The movement of the sliding block 54 can drive the locking tooth 55 to move, so that the locking tooth 55 and the limiting rack 45 are pressed together, thereby locking the position of the limiting slide rod 43 and enhancing the stability of the device during use. When it is necessary to adjust the planting depth, the sliding block 54 can be driven to move in the opposite direction, thereby driving the locking tooth 55 to move away from the limiting rack 45 and releasing the locking state of the limiting slide rod 43.

[0043] Working principle:

[0044] In use, when adjusting the planting depth during corn sowing, pull the connecting block 52. The connecting block 52, through the connecting rod 51, drives the sliding block 54 to move, compressing the return spring 53. The sliding block 54 then drives the locking tooth 55 to move away from the limiting rack 45, releasing the locking state of the limiting slide rod 43. Then, rotate the adjusting handwheel 44, which drives the threaded rod 41 to rotate. The rotation of the threaded rod 41 causes the connecting frame 4 to move. The limiting slide rod 43 limits the movement of the connecting frame 4, preventing it from shifting during movement. The connecting frame 4 then moves the plow head 42, thereby adjusting its height during use. This allows for the creation of furrows suitable for the corn seed sowing depth, facilitating planting. After the depth is controlled and adjusted, the connecting block 52 is released. The return spring 53 moves the sliding block 54 to reset due to its elasticity. The sliding block 54 moves the locking tooth 55, so that the locking tooth 55 and the limiting toothed rack 45 are pressed together, thereby locking the position of the limiting slide rod 43 and enhancing the stability of the device. The corn seeds are placed in the placement box 2, and the drive motor 31 is started. The drive motor 31 drives the drive shaft 33 to rotate. The drive shaft 33 drives the second gear 34 to rotate through the first gear 32. The second gear 34 drives the connecting shaft 23 to rotate. The connecting shaft 23 drives the sowing seat 21 to rotate, thereby scattering the corn seeds that have fallen into the sowing trough 22 for sowing in sequence. The sowing effect is more uniform and convenient to use.
