載の扱深さ調節の自動操作装置。[Scope of Claim for Utility Model Registration] In order to adjust the handling depth, an adjustment lever 2 for operating the vertical conveyance chain 1 etc. to freely change the inclination is inserted into a long guide groove 3, and is inserted downwardly within the guide groove 3. This is a combine harvester in which a helical body 4, which is engaged by the adjustment lever 2 under pressure, is mounted on a motor M that can freely rotate in the forward and backward directions according to signals from the culm length detection sensors 28 and 29. 5 and 6 operating pieces 5a and 6a are provided, and these limit switches 5 and 6 are provided in a signal transmission circuit from the culm length detection sensors 28a and 29a to the motor M on the corresponding side, respectively. An automatic operating device for adjusting the handling depth. Guide grooves 3 located above both ends of the spiral body 4
Switch operating pieces 5a and 6a of both limit switches 5 and 6 for stopping the motor M are respectively extended so as to intersect with the end edges 3a and 3b of the guide groove 3 from the inside with a plane slope. An automatic operating device for adjusting the handling depth as set forth in claim 1 of the utility model registration claim.
