Abstract: The present invention discloses a mobile operating platform for a paddy field, including a body, a power generating device, a movement control system, a draft control system and an automatic leveling system, where the power generating device, the movement control system, the draft control system and the automatic leveling system are all mounted on the body. The present invention has a compact overall structure, and utilizes the pressure of a water flow to realize the movement of the platform, and can fully utilize the characteristics of the water flow to reduce power consumption, and avoid the use of a heavy and complicated traditional walking device, the entire mobile operating platform for a paddy field does not contact the ground, saving mechanical power and avoiding damage to an aquatic crop; the draft control system adjusts a draft by the amount of water filled in a closed cavity in the body.

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.
