Abstract: The present invention discloses an opposite belt-type precise seeding device. The opposite belt-type precise seeding device comprises a seed metering tube consisting of a U-shaped shell and a cover plate, two conveying devices provided inside the seed metering tube in parallel, and a conveying plate provided at the lower end of the seed metering tube. The opposite belt-type precise seeding device belongs to the field of agricultural machinery. In a seeder, a tubular seed conveying tube is usually used for guiding movement of seeds, but the movement of the seeds in the seed conveying tube has certain randomness, so that the seed distance consistency of the seeds in a seed bed is reduced. Through control of the seeds by the conveying devices, the stable movement of the seeds is achieved and the seed distance consistency of the seeds in the seed bed is guaranteed.
