Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheat seed sowing technology, and to a device for adjusting the sowing depth of dry alkali wheat in saline-alkali land. Background Technology
[0002] Saline-alkali land, as a special type of soil, presents great challenges to crop cultivation due to its high salt and alkali content, complex soil structure, and poor physical and chemical properties. As one of the main crop varieties adapted to saline-alkali land environment, the sowing process plays a decisive role in the final emergence rate, growth status, and yield. Precise control of sowing depth is a key factor in ensuring the good growth of saline-alkali wheat.
[0003] According to the public announcement (CN220897159U), a drought-resistant wheat seeder for sowing in saline-alkali land is disclosed. This technology discloses a technical solution that includes "a seed storage hopper and a water tank, with the seed storage hopper and water tank fixedly connected and a connecting seat connected to the water tank. The bottom of the seed storage hopper is connected to multiple seeding pipes through a seeding structure. The bottom of the water tank is rotatably connected to a rotating water jacket. The bottom of the water tank is rotatably connected to the side wall of the rotating water jacket through a connecting pipe. The rotating water jacket is axially connected to multiple ground-inserted water outlet structures, etc. This technology can realize sowing and watering operations at one time. It can also sow while moving, solving the problem of local sowing volume being too large or too small. At the same time, when watering, the water outlet can be inserted into the saline-alkali land to reduce water from being poured from the saline-alkali ground and causing some water to evaporate naturally, ensuring that the saline-alkali land receives sufficient moisture and further ensuring the smooth progress of sowing."
[0004] However, in the aforementioned comparative documents, although the use of the drought-resistant wheat planter reduces the natural evaporation of water caused by water being poured onto the saline-alkali ground through multiple ground-inserting water outlet structures, ensuring that the saline-alkali land receives sufficient moisture and further ensuring the smooth progress of sowing, saline-alkali land is a special type of soil with high salt and alkali content, complex soil structure, and poor physical and chemical properties. Moreover, saline-alkali land varies greatly. In the aforementioned comparative documents, the sowing depth cannot be adjusted during sowing, which may lead to sowing depth that is too shallow. As a result, the seeds are easily damaged by high concentrations of salt, the germination rate is greatly reduced, and even if they germinate, the seedlings are often weak and unable to withstand the harsh environment.
[0005] To address the aforementioned issues, this application proposes a device for adjusting the sowing depth of drought-resistant wheat in saline-alkali land. Utility Model Content

The adjustment component 2 includes a motor 201, with a rotating rod 202 fixedly connected to the shaft of the motor 201. The motor 201 is used to rotate the rotating rod 202. A first bevel gear 203 is fixedly connected to the outer wall of the rotating rod 202. The rotation of the rotating rod 202 drives the rotation of the first bevel gear 203. A limit block 206 is fixedly connected to the bottom of the seeder 1. A second bevel gear 204 is rotatably connected to the side of the limit block 206 near the first bevel gear 203.

The top of the threaded block 304 is fixedly connected to a control plate 305. The movement of the threaded block 304 will drive the control plate 305 to move. The control plate 305 is slidably connected to the seeding tube 4. The movement of the control plate 305 will cause the through hole on the control plate 305 to be misaligned with the through hole of the seeding tube 4, thereby adjusting the seeding quantity and preventing insufficient or excessive seeding, thus avoiding low land utilization or poor seedling growth.

[0036] Working principle:
[0037] This device for adjusting the sowing depth of saline-alkali wheat in saline-alkali land works by using a motor 201 to drive a rotating rod 202 when the sowing depth needs to be adjusted. The rotation of the rotating rod 202 drives a first bevel gear 203, which in turn drives a first threaded rod 205 through a meshing second bevel gear 204. The rotation of the threaded rod 205 then moves a sliding block 207 and a furrow opener 208, thereby adjusting the furrow opener 208 and achieving sowing at different depths. This provides a good germination environment for the seeds, allowing them to better contact the soil. The rotation of the rotating rod 202 causes the third bevel gear 301 to rotate, which in turn drives the second threaded rod 303 to rotate via the meshing fourth bevel gear 302. The rotation of the second threaded rod 303 causes the threaded block 304 and the control plate 305 to move. This allows the holes on the control plate 305 to be misaligned with the holes on the seeding tube 4, thereby controlling the rate at which the wheat seeds fall. This prevents under- or over-seeding, thus avoiding low land utilization or poor seedling growth.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
