[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 Figures 1-4In this embodiment of the utility model, a wheat planting and sowing device includes a support 1. A sowing box 2, which is set in an inclined state, is fixedly installed in the top groove of the support 1. A seed dispensing pipe 4, which penetrates into the inner cavity of the sowing box 2, is set below the sowing box 2. The seed dispensing pipe 4 is set in a vertical state. A seed inlet pipe 3, which protrudes upward, is integrally formed at the outer periphery of the sowing box 2 away from the seed dispensing pipe 4. A seed picking mechanism that extends into the interior of the sowing box 2 is installed on the outside of the sowing box 2. An acceleration mechanism that penetrates into the interior of the vertical part of the seed dispensing pipe 4 is installed on the outside of the vertical part of the seed dispensing pipe 4.

[0019] In this embodiment: Wheat seeds enter the interior of the seeding box 2 through the seed inlet tube 3. At this time, the seed picking mechanism is activated, which picks up the wheat seeds one by one and contacts the inlet of the seed dispensing tube 4 during rotation. After the inlet of the seed dispensing tube 4 contacts the wheat seeds, the wheat seeds and the seed picking mechanism are blocked by the inlet of the seed dispensing tube 4. At this time, the wheat seeds fall down along the seed dispensing tube 4. During the fall, they are accelerated by the acceleration mechanism, which further accelerates the falling speed of the wheat seeds and improves the sowing efficiency. Secondly, the structural design of the acceleration mechanism can avoid the airflow of the acceleration mechanism from affecting the interior of the seeding box 2.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The seed-collecting mechanism includes a rotary motor 5 fixedly installed at one end of the seeding box 2. The output shaft of the rotary motor 5 passes through the interior of the seeding box 2 and is connected to a rotating disk 10. The rotating disk 10 is rotatably installed in the inner cavity of the seeding box 2 and is arranged parallel to the seeding box 2. Multiple seed suction holes 8 are equidistantly opened in the circumference of the rotating disk 10. An outwardly protruding exhaust pipe 7 is integrally formed at the end of the seeding box 2 away from the rotary motor 5. The exhaust pipe 7 is connected to the input end of the No. 1 air pump through a pipe. A protective sleeve 9 is integrally formed at one end of the inner wall of the seeding box 2 and is sleeved with the output shaft of the rotary motor 5. The inlet of the seed dispensing pipe 4 abuts against one side of the rotating disk 10. A notch is formed at the position where the inlet of the seed dispensing pipe 4 abuts against the seed suction hole 8.

[0021] In this embodiment: During sowing, the rotary motor 5 runs, driving the rotating disk 10 to rotate. At the same time, the suction force generated by the No. 1 air pump draws the gas inside the sowing box 2 outward through the pipe and exhaust pipe 7. Under negative pressure, the wheat seeds adhere to the end of the seed suction hole 8 near the rotary motor 5, and the wheat seeds rotate accordingly. During the rotation, the wheat seeds gradually approach the inlet of the seed metering pipe 4 and enter the gap position. At this time, the continuously rotating disk 10 separates from the wheat seeds due to the obstruction of the inlet of the seed metering pipe 4, and the wheat seeds fall down along the seed metering pipe 4.

[0022] Please refer to this carefully. Figure 1 and Figure 4The acceleration mechanism includes an air inlet pipe 6 integrally formed on the outer wall of the vertical rod of the seed metering pipe 4. The air inlet pipe 6 is inclined upwards. The inner cavity of the air inlet pipe 6 is connected to the inner cavity of the seed metering pipe 4. The inner wall of the seed metering pipe 4 is integrally formed with a conical tube 11 above the output end of the air inlet pipe 6. The inner wall of the conical tube 11 has a conical surface structure that is wider at the top and narrower at the bottom. The bottom end of the conical tube 11 is integrally formed with a downward protruding guide tube 12. The inner diameter of the guide tube 12 is equal to the inner diameter of the narrow end of the inner wall of the conical tube 11. The guide tube 12 extends downwards to below the output end of the air inlet pipe 6. The air inlet pipe 6 is connected to the output end of the second air pump through a pipe.

[0023] In this embodiment: During the falling process of wheat seeds, they fall downwards through the inner wall of the cone tube 11 and the guide tube 12. At this time, the second air pump is running, and the second air pump inputs external gas into the air inlet pipe 6. The inclined design of the air inlet pipe 6 enables the gas to flow downwards along the inner wall of the seed metering pipe 4 after entering it. The flowing gas accelerates the falling seeds and helps the seeds to be discharged quickly, thereby improving the sowing speed. The design of the cone tube 11 and the guide tube 12 can prevent the wheat seeds from hitting the inner wall of the seed metering pipe 4 when the gas enters the seed metering pipe 4 along the extension direction of the air inlet pipe 6. After the gas moves downwards, its airflow direction changes and flows along the seed metering pipe 4, which can carry the seeds and accelerate their fall.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
