Connect the inner wire (39) of the wire (38) to the tip of the adjustment arm (33). and fixed when pulling the inner wire (39) against the spring (34). The horizontal beam (13) is opened by increasing the relative distance between the movable plate (32) and the plate (31). In other words, the leakage amount is adjusted to increase by increasing the inclination angle of the horizontal bar (13). ing.

When harvesting wet materials such as morning dew or wet rice after rain, the flow rate sensor is The sensor (55) detects the grain flow rate above a certain level, and the humidity sensor (56) detects the grain humidity. When a certain level or more is detected, the swing motor (45) is driven to move the horizontal bar (13) back and forth. In addition to double-swinging, when the grain flow rate is below a certain level at the beginning or end of mowing, When the grain humidity is normal, the horizontal rail (1) is driven by driving the horizontal rail motor (42). 3) is used to perform the tilt angle control.

[0011] Therefore, when controlling the swing of the horizontal crosspiece (13), the operating time varies depending on the humidity level. is set, and the humidity detected by the sensor (56) is in the A zone of the low humidity range. When the unit is in the B zone of the medium humidity range, the unit operates intermittently for a short period of time within a certain period of time. At some point, intermittent operation for a long time within a certain period of time occurred in zone C, which had a high humidity range. Continuous driving is performed to prevent clogging at this horizontal bar (13), and also to prevent rocking. The load sensor (5) detects the occurrence of grain clogging on the horizontal crosspiece (13) during operation. 7) When detected, the alarm device (60) is activated to notify the worker of this. It is something that

[Effect of the idea]

As is clear from the above examples, the present invention is a technology that separates and removes straw waste from threshed grains. In a swinging sorting machine (9) equipped with a chaff sieve (13), the chaff sieve (1 3) The control system is equipped with a reciprocating swing mode that swings back and forth within a certain angle range (θ). Because it is a wet material, it is difficult to avoid damage when harvesting wet materials such as morning dew or wet rice after rain. In this case, the reciprocating movement of the chaff sieve (13) facilitates the separation of grains and straw waste. As the straw is advanced, straw debris sticks to the upper working surface of the chaff sieve (13) and accumulates there. This also prevents inconveniences such as straw clogging, resulting in good wet material reaping work without straw clogging. It has remarkable effects, such as making it possible to
