Abstract: PROBLEM TO BE SOLVED: To properly avoid something wrong such as the contact with a field surface, the rushing into the field surface or the like of a reaping part when the front part of a traveling machine body becomes down and the reaping part is on the point of the contact with the field surface by surely lifting the reaping part from the field surface by the lifting operation of a lifting and lowering lever or the like. SOLUTION: The lifting action of a reaping part by operating a reaping part-lifting and lowering means CY so that the reaping part installed so as to be freely lifted and lowered against the traveling machine body having a traveling device may be lifted against the traveling machine body, and the machine body-lifting action for operating a machine body-lifting and lowering means 19 so that a grounding part of a traveling device may be separated from the traveling machine body, are carried out based on the lifting instruction by a manual operation type lifting and lowering instruction means 25. The lowering action of the reaping part for operating the reaping part-lifting and lowering means CY so that the reaping part may be lowered against the traveling machine body, and the machine body-lowering operation for operating the machine body-lifting and lowering means 19 so that the grounding part may approach the traveling machine body, are carried out by the lowering instruction by the lifting and lowering instruction means 25.

Abstract: PURPOSE:To reduce the increase of an operation load on a thresher to a minimum limit and simultaneously prevent short grain stems from remaining without being threshed. CONSTITUTION:In the grain straw-carrying mechanism of a self-threshing type combine harvester, a whole straw-feeding device for freely switching from a state carrying reaped grain straws into a state canceling the nipping of the foot parts of the reaped grain straws and feeding all bodies of the reaped grain straws into a thresher 2, and a nipping position-shifting mechanism for freely controlling a grain straw-nipping position along the longitudinal direction of the carried grain straws in a nipping and carrying device 8 are disposed in the middle way of a grain straw-carrying way for the threshing treatment. When the lengths of the carried grain straw detected with a straw length-detecting means S are shorter than the first set value and longer than the second set value, the nipping position-shifting mechanism is operated so that the grain straw-nipping position in the nipping and carrying device 8 is shifted toward the threshing chamber, and when the lengths of the carried grain straws are shorter than the second set value, the whole straw-feeding device is controlled so as to switched from the nipping and carrying state into the whole straw-feeding state.

Abstract: PURPOSE:To prevent needless increase of load on a thresher while suppressing occurrence of unthreshed grain culm by effectively utilizing a threshing depth adjusting mechanism without complicating the structure. CONSTITUTION:A grain culm transporting mechanism for combine harvester is constituted to hold the foot side of grain culm by a gripping conveyor 8 and to thresh the ear tip side of grain culm in a thresher 2. Apair of grain culm existence sensors S1 and S2 are set in the midst of a transporting passageway for the thresher 2 and a threshing depth adjusting mechanism M1 for regulating the threshing depth of reaped grain culm in the thresher 2 is installed so that the ear tip of grain culm is positioned between both the sensors S1 and S2. A whole culm throwing device capable of releasing holding at the foot side and changeable to a state for feeding the whole culm of reaped grain culm to the thresher 2 is installed. In a state in which the threshing depth adjusting mechanism M1 is adjusted to the deepest threshing side, when the grain culm existence sensors S1 and S2 detect absence of grain culm, the whole culm throwing device is controlled and converted from a holding and transporting state to a whole grain throwing state after the lapse of a given time of transportation of reaped grain culm from the set positions of the sensors S1 and S2 to the whole grain throwing device.
