Abstract: PURPOSE:To enable sure and easy recognition of the steering state while driving a reaper harvester in comfortable posture. CONSTITUTION:A plurality of grass-dividing tools 4A, 4B, 4C, 4D are arranged in the lateral direction of a machine body interposing gaps therebetween and attached to the tip end of a reaping part 3 placed at the front part of the machine body V. The lateral position of a culm introduced between the grass- dividing tools 4A, 4B, 4C, 4D is detected by position detection means S2, S3. The relative position between the culm and the grass-dividing tools 4A, 4B, 4C, 4D in the lateral direction of the machine body is displayed on a displaying means 20. The locus of the relative position between the culm and the grass- dividing tools 4A, 4B, 4C, 4D from the start to the present position is displayed on the displaying means 20 based on the information stored in a memory means 100 which samples and stores the detected position information of the position detection means S2, S3 at intervals of prescribed running distance or prescribed running time.

Abstract: PURPOSE:To prevent the natural falling of treated articles on a vibrational grading plates by fully opening the chaff sieve opening degree of the vibrational grading plate by a controlling means with the stoppage of a thresher. CONSTITUTION:As a threshing switch is switched off to stop a thresher 2, the chaff sieve-opening degree of a vibrational grading plate 19 is fully opened by a controlling means, thereby permitting to prevent the clogging of treated articles in the first opening 20 and the second opening 21 and simultaneously prevent the temporary deterioration of the grading precision when again driven.

Abstract: PURPOSE:To carry out precise control over the throughput by regulating the throughput based on a correction computed value different from other grading modes in a grading mode with a grading mode selecting means. CONSTITUTION:The target value of a throughput of grader (B) is set according to the feed rate of grain culms to a threshing chamber (A). The correction arithmetic processing of the target value is preformed according to the thickness of a layer of substances to be treated on a shaking and grading plate 19. In at least one grading mode selected by a grading mode selecting means, the correction arithmetic processing different from other grading modes is carried out. Thereby, the grading accuracy can be prevented from unnecessarily deteriorating while preventing clogging according to the thickness of the layer of the substances to be treated in the grading mode in which a clogged state readily occurs.

Abstract: PURPOSE:To justify the throughput capacity even when the supply of grains and culms is unknown by controlling the throughput capacity of a grader corresponding to the thickness of layers of crops to be treated on a vibration-grading plate if a detected value of the grain and culm supply to a threshing chamber is beyond a prescribed range. CONSTITUTION:When the supply of grains and culm is unknown, e.g. due to trouble in a unit for detection of the grain and culm supply capable of detecting the supply of grains and culms to a threshing chamber (A) or due to detachment thereof, the throughput capacity of a grader is controlled based on the thickness of crop layers to be treated on a vibration-grading plate 19.

Abstract: PURPOSE:To properly dissolve a state of clogging without lowering the accuracy of separation too much 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 a prescribed value, the capacity of a separator (B) is kept to a value larger by a prescribed value than that immediately before changing to that state. In case the thickness of the layer of materials to be treated continues to be kept to a value larger than a prescribed value for a prescribed time, the capacity of the separator (B) is kept to a value more larger by the prescribed value.

Abstract: PURPOSE:To, in a state where clogging occurs or a state where a sign of clogging is shown, dissolve those states without fail by keeping the capacity of a separator to a prescribed capacity when the thickness of a layer of materials to be treated on a shaking sifter is larger than a prescribed value. 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 a prescribed value, the capacity of a separator (B) is kept to a prescribed value. If the supply of grains and culms is reduced, the amount of the materials to be treated on the shaking sifter is reduced, thus enabling dissolution of the clogging state or avoidance of the state without fail.

Abstract: PURPOSE:To maintain stabilized sieving motion performance by controlling chaff sieve so as to operate on open side when the detection amount of a sieve sensor becomes upper limit or above in prescribed range and so as to operate on closed side when the detection amount becomes lower limit or below. CONSTITUTION:A control device adapts average value of time longer than oscillating cycle of an oscillating and sorting plate 3 and the average value is obtained as detection value corresponding to thickness of layer of a treated material. When thickness of layer of the treated material becomes upper limit or above in preliminarily set range (insensitive band), chaff sieve 8 is operated on open side to increase the leak amount of the treated material. On the contrary, when thickness of layer of the treated material becomes lower limit or below of insensitive band, chaff sieve 8 is operated on the closed side to decrease the leak amount of the treated material. Thereby thickness of layer of the treated material can be kept nearly constant and stabilized sieve action performance can be maintained.

Abstract: PURPOSE:To accurately detect a shift in the position of the external surface part of an object to be detected without any electric correction by changing plural kinds of combination of pieces of detection information of plural detection parts as a disk rotate. CONSTITUTION:A sensor which detects the position of the top surface of a straw layer is provided to arch metal 20 fixed to a receiving net 5. The sensor S consists of a contactor 21 which is provided while enabled to swing freely in the conveying direction of a processed body, a disk 22 which turns integrally around the same axis P with the contactor 21, and four optical pickup devices 24a - 24d which read whether or not slits 23a - 23d formed in the disk 22 are present or not from transmitted light, and connected to a controller H through four signal lines L1 - L4 connected to the devices 24a - 24d. Then the slits 23a - 23d change plural kinds of combination of pieces detection information of the devices 24a - 24d as the disk 22 rotates and the length in circumferential directions where plural kinds of combination appear is so set that the combinations change every time the position shift increases or decreases by a set quantity.

Abstract: PURPOSE:To detect clogging of material to be treated between a chaff sieve and a straw rack by simple remodeling, by equipping a contact type sensor in such a state that the sensor has an action to detect thickness of a layer of material to be treated on a chaff sieve. CONSTITUTION:An oscillating and selecting plate 3 is equipped with a chaff sieve 8 which backward transports a material to be treated dropped from a receiving net 5 of a squeezing chamber A while oscillating and selecting and a straw rack 9 which backward transports the material to be treated discharged from a dust sending hole 6 at the rear of the receiving net 5 in a such a state as to position the straw rack 9 above the straw sieve 8 at an interval. A contact type sensor S to detect thickness of the layer of the material to be treated on the chaff sieve 8 is laid in such a state that the sensor detects the thickness of the layer of the material on the chaff sieve 8 corresponding to a position just before the straw rack 9. By this inexpensive and simple remodeling, clogging of the material to be treated between the chaff sieve and the straw rack can be detected.
