Abstract: PURPOSE:To provide a system designed to detect stem positions in high accuracy even if the traveling conditions such as speed for a reaper are changed. CONSTITUTION:The objective system has (A) a stem position detective means R to detect such position after stem movement in the lateral width direction of the machine body on contact of a stem with a contact piece 10 which is free to move in said, direction and installed in such a state as to be returningly energetized on the side of stems aligned at specified planting intervals longitudinally for the machine body, (B) a sampling means 100 to sample the information given by the means R at each specified traveling distance or time, and (C) a discriminating means 101 to determine stem position along said direction based on the information from the means 100. The means 101 determines the maximum value among plural number of the information from the means R sampled during the machine body travels at least planting distance as the stem position along the lateral width direction for the machine body.

Abstract: PURPOSE:To justify the throughput capacity of a grader at a time when reaping is completed by controlling the throughput capacity of the ffrader corresponding to the thickness of layers of crops to be treated on a vibration-grading plate if the grain and culm supply to a threshing chamber stops. CONSTITUTION:When the supply of grains and culms to a threshing chamber (A) stops, the throughput capacity of a grader is controlled based on the thickness of crop layers to be treated on a vibration-grading plate 19 of the grader. The grading accuracy at a time when reaping is completed can be improved thereby and loss can be reduced.

Abstract: PURPOSE:To simplify the constitution and to improve detecting accuracy by providing a plurality of contact parts in a detecting body at the different phases, and constituting the intervals between the tips and the supporting points of the contact parts so that the intervals become sequentially small. CONSTITUTION:In a height detecting apparatus, a detecting body 20 and a sensor 21 for detecting the moving angle of the detecting body 20 are provided. The height is detected based on the movement of the detecting body 20 from the initial attitude. Two plate-shaped contact parts S1 and S2 in the different phases are provided in the detecting body 20. The intervals between the respective tips and supporting points of the contact parts S1 and S2 are constituted so that the intervals become sequentially small. When the height of a material to be processed is increased, the contact parts S1 and S2 are sequentially brought into contact with the upper part of the material to be treated. Thus, the detecting accuracy can be improved. The detected data of the height detecting apparatus, i.e., the outputs of the output signal of the sensor 21, are periodically changed with the movements of the movement selecting plates. Therefore, the output signals are sampled at a preset period. Then, a plurality of average values can be used as the data corresponding to the height.

Abstract: PURPOSE:To rapidly dissolve a state of clogging by attaching a control unit capable of adjusting the capacity of a separator to a specified state according to the thickness of a layer of materials to be treated on a shaking sifter. CONSTITUTION:The thickness of a layer of materials to be treated on a shaking sifter 17 is monitored by a sieve sensor (S4). In case the thickness of the layer of materials to be treated is larger than the first set value and lower than the second set value (state immediately before clogging), the capacity of a separator (B) is controlled not towards the reduction side but only towards the increase side. When the thickness of the layer of materials to be treated has a value larger than the second set value (state of clogging), the capacity of the separator (B) is kept to a value of the maximum capacity or a value in the vicinity thereof.

Abstract: PURPOSE:To keep the grading accuracy by keeping the treating capacity to a prescribed level when the thickness of the layer of the treating object is thinner than a prescribed level. CONSTITUTION:The thickness of the layer of the treating object on a vibration grading plate 17 is detected by a sieve sensor S4 of a treating object volume detection means. When the detected level is decreased below a prescribed level, a controlling means lowers the opening degree of a chaff sieve by two grades and sets the opening degree as the final controlling level of the chaff sieve and, at the same time, lowers the air flow of a winnower by one grade to decrease the treating capacity of the grading apparatus B by a prescribed level by the combined effect of the lowering of the chaff sieve opening and the air flow. The volume of the treating object is gradually increased after the above adjustment. The grading accuracy of the chaff sieve 20 and the winnower 16 of the grading apparatus B can be maintained by this process.

Abstract: PURPOSE:To reduce occurrence of an error by discriminating whether the thickness of materials for treatment within the set proper range or not based on signals from plural sensor parts at different intervals from rocking grating plates. CONSTITUTION:The interval between a rocking grading plate 3 and plural sensor parts (S1) and (S2) are different so as to produce a physical difference in the thickness itself of materials for treatment sensed by each of the plural sensor parts. For example, an error is hardly caused even if a difference is produced in the extent of thrusting of the materials for the treatment into the respective sensors.

Abstract: PURPOSE:To prevent the unnecessary steering of a frame on the non-reaped side by directing the frame on the non-reaped side only when the detection of the absence of stem straws fed in a path on the most reaped side is continued for a prescribed time. CONSTITUTION:The presence or absence of stem straw fed into a path L3 is judged on the basis of the detection state of a reaped side sensor S3 for detecting a lateral distance between step straws fed into the path L3 on the most reaped side and the end of the reaped side and on the basis of the detection state of a non-reaped side sensor S2 for detecting a lateral distance between the stem straws fed into the path L3 and the end of the non-reaped side. Only when the detection of the absence of the stem straws is continued while the frame travels for a set time or for a set distance, the frame is directed on the non-reaped side to reduce the zigzag travel of the frame caused by the steering operation.

Abstract: PROBLEM TO BE SOLVED: To provide a structure for regulating the engine speed of a combine harvester capable of saving energy of operation. SOLUTION: This structure for regulating the engine speed of the combine harvester is obtained by linking an operating system 105 extending from an accelerator lever 100 to a speed regulating lever 104 of an engine 55 through a linking mechanism 111 to a threshing clutch lever 103, changing over the speed regulating lever 104 from the set position corresponding to an operating position of the accelerator lever 100 to a rated position b for subjecting the engine 55 to rated rotation interlocking with the operation of the threshing clutch lever 103 from a disengaged position to an engaged position when the engine speed is lower than the rated speed and composing the linking mechanism 111 so as to return the speed regulating lever 104 from the rated position b to the set position a interlocking with the operation of the threshing clutch lever 103 from the engaged position to the disengaged position.

Abstract: PROBLEM TO BE SOLVED: To provide a reaping part supporting structure constituted to operate a reaping part so as to be properly opened the reaping part sideways even at a place where a machine body subsides in a reaping harvester. SOLUTION: This reaping part supporting structure for a reaping harvester is equipped with a drop obstruction mechanism 24 to be operated in an obstruction state in which when a reaping part is lifted and driven to a fixed height, the drop of the reaping part from the fixed height is obstructed with the lifting. The structure is provided with supporting mechanisms 15 and 16 for holding the reaping part openably sideways around a longitudinal shaft center P1 at the front of machine body in the obstruction state of the drop obstruction mechanism 24 in which the reaping part is lifted and driven to the fixed height.
