[0019] See also Figure 1 A sowing mechanism includes a seeder body 1, a plurality of seeding parts 5, a mounting arm 9, and a vertical driving part.

[0020] See also Figure 1 , Figure 2 , Figure 3 In one embodiment, a plurality of the seeding parts 5 are arranged on the seeder body 1 in a transverse arrangement, one of the seeding parts 5 is fixedly connected to the seeder body 1 by welding, and the other seeding parts 5 are slidably connected to the seeder body 1 in a transverse direction. Furthermore, a first slide groove 4 is transversely arranged on the seeder body 1, and a first slider 8 is fixedly arranged on each of the seeding parts 5, and is slidably or fixedly connected to the first slide groove 4 through the first slider 8.

[0021] See also Figure 1 The upper end of the seed-discharging part 5 is located in front of the seed box 2, and the position of each seed-discharging part 5 corresponds to an outer groove wheel 3. Each seed-discharging part 5 includes a funnel part 6 at the upper end and a pipe part 7 at the lower end. The large mouth of the funnel is at the top and the small mouth is at the bottom. The pipe part 7 is connected to the small mouth at the lower end of the funnel part 6. Each funnel part 6 is used to catch a seed pushed out by the outer groove wheel 3 and make it fall into the soil along the pipe part 7.

[0022] See also Figure 1 , the mounting arm 9 slides vertically above the seeding portion 5, and a plurality of trapezoidal blocks 10 (a trapezoid with the bottom on top) with a width on the top and a width on the bottom are arranged in a horizontal arrangement at the lower end of the mounting arm 9, and the trapezoidal blocks 10 are all slidably connected to the mounting arm 9 in a horizontal direction. Furthermore, a second slide groove 12 is lateraly arranged at the lower end of the mounting arm 9, and a second slider 11 is fixedly arranged at the upper end of each of the trapezoidal blocks 10 by welding or integral molding, and is lateraly slidably connected to the second slide groove 12 by the second slider 11.

When the trapezoidal block 10 moves downward, the seeding parts 5 on both sides thereof will be pushed open to both sides, so as to adjust the spacing between them, and the trapezoidal block 10 will move with the movement of the seeding parts 5. When the trapezoidal block 10 moves upward, under the action of the spring 13, the seeding parts 5 on both sides will continue to fit the trapezoidal block 10 to reduce the spacing. The size of the trapezoidal block 10 is designed so that each of the seeding parts 5 will not slide out of the range of the corresponding outer groove wheel 3, so as to achieve the effect of adjusting the spacing between the seeding parts 5 within a certain range (in agricultural planting, in order to avoid wasting land planting area, the adjustment range of sowing spacing is generally not too large).
