When the positions of the through hole 321, the seed placement hole 311 and the inlet 331 in the vertical direction coincide, the seeds in the seed placement hole 311 fall from the seed placement hole 311 into the seed delivery pipe 33, and then fall to the ground for seeding. In the present application, the spacing between adjacent seed placement holes 311 is equal. When the rotating tray 31 rotates at a constant speed, the time intervals for the seeds to fall are the same, so that the spacing between the planted seeds is the same, so that the seeds are evenly distributed, the space is used to the maximum extent, the yield of the crop is increased, and nutrients and water can be used more fully.

[0033] See also Figures 1 to 5 The seeder includes: a base frame 1, a seed delivery unit 3 and a controller 4.

[0034] The base frame 1 is the frame of the seed drill, and is used to fix other components. The shape of the base frame 1 is not limited, including but not limited to a rectangular parallelepiped, an irregular body, etc. The base frame 1 has a large structural strength to adapt to the resistance of the seed drill during the seeding process.

[0035] The moving part 2 is arranged on the base frame 1 to drive the base frame 1 to move. The moving part 2 is electrically connected to the controller 4, and the moving part 2 drives the base frame 1 to move at a uniform speed at the speed in the instruction according to the movement instruction of the controller 4. In one embodiment, the moving part 2 includes a driving part and a plurality of wheels, the wheels are rotatably arranged on the base frame 1, the driving part is fixedly arranged on the base frame 1, and the driving part drives the wheels to rotate, thereby moving the base frame 1.

[0036] The seed delivery part 3 includes a rotating tray 31, a support frame 32 and a seed delivery pipe 33.

The distance between the through hole 321 and the rotation center of the rotating tray 31 is the same as the distance between the seed hole 311 and the rotation center of the rotating tray 31. As the rotating tray 31 rotates, when the position of the seed hole 311 coincides with the through hole 321, the seeds in the seed hole 311 pass through the through hole 321 due to gravity and fall into the seed delivery pipe 33, and finally fall to the ground from the outlet 332 of the seed delivery pipe 33, completing the sowing. Since the spacing between adjacent seed holes 311 is equal and the rotating tray 31 rotates at a uniform speed, the time interval for each seed to fall from the seed hole 311 to the ground is the same. In this process, the moving part 2 drives the base frame 1 and the seed delivery part 3 on the base frame 1 to move at a uniform speed. After the seeds fall to the ground, the spacing between the seeds is the same, so that the seeds are evenly distributed, the space is used to the maximum extent, the yield of the crop is increased, and nutrients and water can be used more fully.
