Abstract: PROBLEM TO BE SOLVED: To provide a combine harvester enabling the stable travel of the harvester frame and improving the operation efficiency without relating to the change in the weight of a grain-recovering member by arranging a thresher and the grain-recovering member on the frame. SOLUTION: A pair of right and left crawler travel devices are supported on support frames 3 in a prescribed lateral distance. The support frames 3 are provided with slide operation means 6 which laterally slidably support the harvester frame 5 and is used for laterally sliding the frame 5 on the basis of the support frame 3. A thresher and a grain-recovering member such as a grain tank for storing the grains are laterally arranged on the frame 5.

Abstract: PURPOSE:To prevent clogging of transferring culm caused by volume change with time and to detect the clogging at the backside end of a holding rail with excellent sensitivity in a culm-transferring apparatus in which the holding rail is forced to approach a transferring chain side and a sensor for detecting culm-clogging by detecting the larger distance from the holding rail to the transferring chain than predetermined length is placed. CONSTITUTION:This culm-transferring apparatus is constructed as follows: a swing arm 12 is placed in such a manner as to freely swing in approaching-and-leaving direction against a transferring chain 14, and in a state forced to swing to approach the transferring chain 14 by a forcing means 18; a holder 16 fixedly supporting a holding rail 15 is placed on the swing arm 12 in such a manner as to freely rotate around a center X of a shaft almost perpendicular to the longitudinal direction of a holding rail 15 and directing in the longitudinal direction of transferring culm; stoppers 29a, 29b for checking, by touching, the rotation around the center X of the shaft of the holder 16 in the direction in which a space between the back end side of the holding rail 15 and the transferring chain 14 becomes larger than that between the front end side of the holding rail 15 and the transferring chain 14; and a culm clog-detecting sensor 2 is placed in a state capable of detecting the swing of the swing arm 12 in the direction to leave the transferring chain 14.

Abstract: PURPOSE:To obtain a control section of the head-feeding type combine harvester capable of preliminarily preventing the damage of the device due to the clogging of a carriage route and improved in grain-recovering efficiency by disposing a control means for automatically controlling the volume of a grading wind, etc., on the basis of a detected threshing load, etc. CONSTITUTION:In this control section of the head-feeding type combine harvester, an analogue type sensor 22 for detecting the moving distance of a plant foot-carrying chain 14 from a nipping rail 15 in a plant foot-nipping and carrying device 8 for feeding grain culms into a threshing feed chain is disposed, and a control means for automatically controlling at least one of a grading wind volume and a chaff sieve opening degree on the basis of the information of the analogue type sensor 22 is also disposed. An alarm device operated when the analogue type sensor 22 detects that the nipping rail 15 is moved from the plant foot-carrying chain 14 at a larger distance than a prescribed distance is preferably disposed.
