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: A system and a method for controlling a reel of a combine harvester, wherein, the system comprises a satellite positioning receiver, a driving device, a controller and a rotating speed sensor; the rotating speed sensor collects and transmits an actual rotating speed of the reel to the controller, and the controller provides the driving device with a speed regulation signal according to the actual rotating speed and the operation running speed. The rotating speed of the reel can be automatically, accurately and quickly adjusted according to the operation running speed of the combine harvester during the operation of the combine harvester, and improve the operation efficiency and quality while ensuring the crop feed quantity.
