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 reduce the attitude control power by correcting the larger one preferentially to the smaller one of the angle difference between the detected lateral inclination angle and the preset lateral inclination angle and the angle difference between the detected longitudinal inclination angle and the preset longitudinal inclination angle. CONSTITUTION:The information of various setters and sensors is inputted to a control device 100 for various control. Detected inclination angles are inputted from a lateral inclination angle sensor S3 and a longitudinal inclination angle sensor S2. The detected inclination angles are compared with preset values of a lateral inclination angle setter 27 and a longitudinal inclination angle setter 26 respectively to determine angle differences. The lateral inclination angle difference and the longitudinal inclination angle difference are compared, and the larger angle difference is preferentially corrected. If the longitudinal inclination angle difference is larger, a pitching drive means CY2 is selectively operated, if the lateral inclination angle difference is larger, a rolling drive means CY3 is selectively operated. The attitude control power can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a working machine upward or downward control device which can suitably change and set the upward or downward movement speed of the working portion on a manual upward or downward movement operation and can simultaneously stop an automatic upward or downward movement control in a state that the non-excessive, non- deficient and suitable upward movement of the working portion is surely elevated. SOLUTION: On an automatic upward or downward movement control, a control means 100 operates an upward or downward movement operation means CY so that the height of a working portion from the ground surface is maintained at a set height on the basis of the detection information of a height detection means S4. On a manual upward or downward movement control, the upward or downward movement operation means CY is operated at an upward or downward movement speed set with a manual operation type upward or downward movement speed-setting means 101. When an automatic upward or downward movement control is executed, and when a manual automatic upward or downward movement control is preferentially executed on the basis of the command of a upward or downward movement command means SS to continuously upward move the working portion more than a set upward or downward movement quantity, the control means 100 judges that an automatic control-stopping command is commanded, and stops the execution of the automatic upward or downward movement control.

Abstract: PROBLEM TO BE SOLVED: To provide the subject control system slight in possibility of such an unfavorableness that a working device lift operation is made contrary to the intention of a relevant operator despite enabling commanding both steering and working device lifting activities with a single control lever. SOLUTION: This control system has switches SW1 and SW2 intended for turning command and functioning to detect whether the position, along the lateral width direction of a vehicle body, of a control lever 16 free to make a reciprocating movement control operation along the lateral width direction and longitudinal direction of the vehicle body, respectively, lies within a steering neutral area, left turning command area or right turning command area, and a control level detective sensor 32 functioning to detect whether the position, along the longitudinal direction of the vehicle body, of the control lever 16 lies within a lift neutral area, descending command area or ascending command area, and this control system works in such a way that, when it is detected that the above position of the control lever 16 lies either within the left turning command area or right turning command area, the lift neutral area is expanded compared to the case in detection that the above position lies within the steering neutral area.

Abstract: PROBLEM TO BE SOLVED: To provide a reaping harvester capable of precisely detecting the distance to planted stand stems and culms on the front side of a machine body at plural positions in the transverse width direction of the machine body by setting a distance detecting means for detecting the distance to the planted stand stems and culms in a specific state. SOLUTION: This reaping harvester is equipped with a distance detecting means S3a for detecting the distance to planted stand stems and culms T located in front of a machine body 9 and is obtained by composing the distance detecting means S3a so as to set the detecting direction for the planted stand stems and culms T in a state thereof in the front and rear directions of the machine body 9 in each of the plural set detected positions mutually different in the transverse width direction of the machine body 9 and detect the distance to the planted stand stems and culms T. In the process, the reaping harvester is preferably provided with the distance detecting means S3a in a site on the already reaped side of the mobile machine body 9 and further a boundary position discriminating means for discriminating the boundary between the group of the unreaped stems and culms T where the planted stand stems and culms T are planted stand and the already reaped region adjacent thereto based on the information from the distance detecting means S3a.
