摘要： PROBLEM TO BE SOLVED: To provide a threshing depth controlling mechanism of a combine harvester, capable of controlling the threshing depth controlling mechanism to the deep threshing side when a sensor for rotating position of a reaping part is lifted from a lower position to a higher position by a prescribed distance or above, correcting the level lifted by the reaping part and eliminating trouble so as to keep an ear tip out of contact with a threshing cylinder. SOLUTION: This threshing depth controlling mechanism of a combine harvester is equipped with a sensor 7 for a rotating position of a reaping part for sensing the position of the reaping part when lifting, lowering and rotating the reaping part and a sensor L for the presence or absence of grain culms capable of sensing the presence or absence of the conveyed grain culms in order to automatically control the threshing depth and is capable of judging the positional change to be lifting operations of the reaping part when the sensor 7 for the rotating position of the reaping part is lifted and changed from the lower position to a higher position in a turned ON state of the [sensor L for the presence or absence of the grain culms by a prescribed distance or above, controlling the threshing depth controlling mechanism to the side of deep threshing and correcting the distance lifted by the reaping part. Furthermore, a mechanism for memorizing the position of a vertical conveyor capable of performing the threshing depth control when starting the lifting and lowering of the reaping part is preferably installed in addition to the sensor L for the presence or absence of the grain culms.

摘要： PURPOSE:To dispense with the adjustment in the case of attaching a sensor and to accurately detect the position of a discharging auger by making the sensor insusceptible to the vibration of the machine body and the discharging auger. CONSTITUTION:Grains in a grain tank are discharged by a discharging auger swivellable to change its position. The position of the auger is detected by detecting the rotation angle of a gear 4 for swiveling the auger using a potentiometer 5 supported by an elastic supporting member 6.

摘要： PURPOSE:To prevent the generation of unthreshed culm in a threshing chamber in the reaping and threshing of culm standing near a levee. CONSTITUTION:The objective apparatus is provided with a threshing depth controlling mechanism to adjust the threshing depth of reaped culm, a reaping switch to detect the coupled state of a reaping clutch, a running switch to detect the running motion of the machine body, a culm base sensor S3 to detect the presence of a culm at a side of a culm base transfer chain 2 of a reaping part B and a lift sensor S4 to detect the lifted state of the reaping part B. The threshing depth controlling mechanism is controlled to the deep threshing side by the detection of the 'ON' state by the lift sensor S4 when all of the reaping switch, the running switch and the culm base sensor S3 are in the state of 'ON'.

摘要： PURPOSE:To classify culm lengths into classes more than twice the number of culm sensors, by displacing the vertical position of a neutral zone corresponding to the length of culm upward according to the ratio of the detection time of adjacent culm sensor above the culm sensor to the unit time. CONSTITUTION:A neutral zone is selected corresponding to the culm to be reaped and the vertical position of neutral zone corresponding to the length of the culm is displaced upward according to the ratio of the detection time of the adjacent culm sensor above the culm sensor to the unit time. The vertical position of the neutral zone is continuously altered constantly corresponding to the culm length. The length of culm can be classified into classes more than twice of the number of culm sensors by using only a small number of culm sensors 71, 72, 73, 74 and the threshing depth can be continuously controlled at the optimum level.

摘要： PROBLEM TO BE SOLVED: To favorably secure straight running performance of a vehicle body. SOLUTION: The working vehicle is equipped with a steering operation area detection means detecting the steering operation area of a steering operation tool, a revolution speed detection means detecting the revolution speed of a drive shaft of each traveling part, a control means with these detection means connected to an input side, and a fine adjustment means connected to the output side of the control means and finely adjusting the attitude of a swash plate operating arm installed on either of the variable flow control pumps. When the difference in the revolving speed between the two drive shafts detected with the revolution speed detection means is smaller than a prescribed threshold, though the steering operation area detection means detects a steering operation area exceeding the straight traveling operation area, feedback control is performed so that the difference in the revolving speed between the two drive shafts detected with the revolution speed detection means becomes larger than a prescribed threshold by operating the fine adjustment means in accordance with the steering operation direction, and the attitude of one of the swash plate operating arms is finely adjusted.
