[0007] Specifically, the first rotating disc is provided with a seed storage cavity and a plurality of planting channels. The seeds in the first rotating disc are placed in the seed storage cavity. When one end of the sowing cavity is located in the planting channel, the one end of the sowing cavity is hingedly connected with a baffle at the planting channel, the baffle is rotated, and the one end of the sowing cavity has an opening. Therefore, when the one end of the sowing cavity is located in the planting channel, the one end of the sowing cavity lifts the baffle and inserts into the seed storage cavity. The seeds in the seed storage cavity enter the sowing cavity through the opening of the one end of the sowing cavity, and are inserted into the soil during the downward movement of the sowing cavity, so that the seeds enter the soil.
