Abstract
The invention provides an adaptive control system and a regulating method for the threshing separation load of the combined harvester and the longitudinal axis. The control system mainly comprises entrainment loss monitoring device, grain breaking rate monitoring device, device for regulating clearance of cutting concave outlet, jitter board load monitoring device, return plate load monitoring device and on-line monitoring and control system. According to the differential signal of the impact force sensor and the inertial force sensor, the cutting flow threshing and separating device is calculated by real-time monitoring of the grain breaking rate, the entrainment loss rate, the tangential groove outlet gap, the cutting drum speed and the longitudinal axis drum speed. And the ratio of the threshing separation load of the cut-off threshing separator and the longitudinal-axial-flow threshing and separating device is adjusted at a reasonable ratio range, to meet the difficult to take off, easy to off and other crops of different harvest requirements, to maintain the best threshing capacity and better adaptability.
