One end of the sowing mouth extending out of the outer ring is conical so as to be convenient for being inserted into soil. One end of the sowing mouth extending into the inner side of the outer ring is contacted with the cylindrical outer wall of the main disc, as shown in fig. 9, a seed channel 15 which is obliquely arranged is arranged on the main disc, and the seed channel penetrates through the inner side wall and the outer side wall of the main disc. The outer ring rotates relative to the main body, and after the sowing mouth is aligned with the seed passage, seeds in the seed passage can slide into the sowing mouth. The outside of the main disc is provided with a thumb wheel 32 which is fixedly connected with the movable nozzle, the thumb wheel is provided with teeth, and after the thumb wheel is contacted with the second end of the driving rod, the driving rod can drive the thumb wheel to rotate so as to drive the movable nozzle to rotate relative to the sowing nozzle, so that the sowing nozzle is opened, and seeds in the sowing nozzle fall into a seed hole at the moment.

As shown in fig. 1 and 3, a seed storage groove 14 is arranged on the main disk, and the opening of the seed storage groove 14 is communicated with the cavity on the inner side of the main disk. The seed storage groove is communicated with a seed inlet 16 on the front side wall of the main disk, seeds enter the main disk through the seed inlet and then enter the seed storage groove, and the seed taking mechanism takes out the seeds in the seed storage groove. As shown in fig. 2 and 3, the seed taking mechanism comprises a seed taking wheel 4 rotatably mounted on the inner side of a main disc, a central gear 62 fixedly connected with the seed taking wheel, a gear ring 6 fixedly connected with an outer ring, and a plurality of planetary gears 61 arranged between the gear ring and the central gear, wherein the planetary gears are rotatably connected with the main disc, and when the outer ring rotates, the gear ring can be driven to rotate, so that the planetary gears are driven to rotate, and the central gear is driven to rotate. Thereby driving the seed taking wheel to rotate. As shown in fig. 7, a seed taking groove 41 is formed in the cylindrical outer wall of the seed taking wheel, a plurality of partition plates 42 are arranged in the seed taking groove, the partition plates divide the seed taking groove into a plurality of independent seed taking cavities, and the seed taking cavities can only accommodate a fixed number of seeds, such as one seed, two seeds and the like. In use, as shown in fig. 8, seeds are introduced into the seed storage tank through the seed inlet, and as shown in fig. 9, when the seed taking wheel rotates to a position where the seed taking tank is communicated with the opening of the seed storage tank, seeds in the seed storage tank 14 enter the seed taking cavity. As shown in fig. 10, as the seed taking wheel continues to rotate, the seed 7 in the seed taking cavity can enter the seed way under the dead weight after the seed taking cavity moves to be communicated with the seed way. The gear ring, the planetary gears and the sun gear form a linkage unit for driving the seed taking wheel to rotate along with the outer ring.
