3. The direct seeding method of rice as claimed in claim 2, wherein: the opening is arranged on the inclined wall.
4. The direct seeding method of rice as claimed in claim 1, wherein: the seed protection device is composed of a roller and a belt wheel.
5. The direct seeding method of rice as claimed in claim 4, wherein: the number of the rollers is three, and the vacancy rate is 10%.
6. The direct seeding method of rice as claimed in claim 1, wherein: the seed metering device shell is also provided with two guard plates which are respectively positioned at two sides of the seed protection device.
7. The direct seeding method of rice as claimed in claim 1, wherein: the upper surface of the hopper main body is provided with a purging opening, and a cover is arranged on the purging opening.
8. The direct seeding method of rice as claimed in claim 1, wherein: the straight through hole of the rotating disc is aligned with the primary seed filling channel to be a first position, the inclined through hole of the rotating disc is aligned with the secondary seed filling channel to be a second position, and the first position is switched to the second position when the motor rotates for 45 degrees.
9. The direct seeding method of rice as claimed in claim 1, wherein: the middle of the seed sowing wheel is provided with a rotating shaft.
10. The direct seeding method of rice as claimed in claim 9, wherein: the rotating shaft is connected with a rotation driving device.
