Abstract
PURPOSE:To improve operation efficiency holding the threshing load state of a combine, etc., proper, by holding a difference between the rotational frequency of a prime motor in an unloaded state and that in a loaded state between the preset upper and lower limits of the rotational frequency. CONSTITUTION:A rice-plant sensor 1, when there is a rice plant in a rice plant passage, turns on to send a signal to a storage circuit 4. The rotational frequency N of a threshing barrel is found by a rotation sensor 2 and a rotational-frequency measuring instrument 3 and sent to the storage circuit 4 and a comparing circuit 5. As a rice cutting machine starts cutting rice plants, the rice-plant sensor 1 turns on and a rotational frequency N0 at that time is stored and held as a value when a threshing load is not applied. In an arithmetic parts 6, rotational frequencies N1 and N2 which correspond to the upper and lower limits of the load are preset, and N0-N1=M1 as a lower-limit signal and N0-N2=M2 as an upper signal are sent to the comparing circuit 5, and M2-N1 is the range of the load. Threshing is started, and the rotational frequency N varies according to variations of both the threshing and cutting loads; and the comparator 5 detects the states of the loads, and they are displayed on display devices 10-12 through an output circuit 9. Thus, the proper load state is held.
