DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rocking sorting plate for sorting a leaked material from a handling chamber, and a strip-shaped member juxtaposed in the workpiece transfer direction. An actuator for moving the strip-shaped member is provided in order to change and adjust the gap formed between adjacent ones of the strip-shaped members provided with a chaff sheave configured, and a grain culm is provided in the handling chamber. A grain culm supply detecting means for detecting whether or not it is being supplied is provided, and while the set time elapses from the time when the grain culm supply detecting means detects grain culm non-supply, the gap is smaller than the minimum value. In order to obtain a set value that is also large and close to the minimum value, the closing control means for the residue that operates the actuator, and the gap becomes the minimum value as the set time elapses. In order to achieve Minimum for the closing control means for relating sorting controller threshing apparatus provided with.

[Conventional technology]

When the grain culm supply to the handling room is stopped, the sorting control device of the threshing device remains in the handling room by adjusting the gap of the chaff sieve to a set value that is larger than the minimum value and close to the minimum value. This makes it possible to perform a sorting process for a treated product that leaks in the handling chamber while suppressing a straw waste from being mixed into the grains to be sorted and collected. Moreover, after that, by minimizing the gap between the chaff sheaves, it is possible to prevent the straw debris from being mixed into the grains to be sorted and collected, and at the same time, to promptly discharge the straw debris to the outside of the device. is there.

By the way, it is conceivable to set the set time for adjusting the gap to a constant time by the closing control means for the residual material. (Prior art documents cannot be described.) [Problems to be solved by the invention] The more processing substances remain in the handling chamber, the longer the time required for the handling processing and the sorting processing. Therefore, if the time for operating the closing control means for the remnant is made constant regardless of the amount of the remaining processed material, a large amount of straw debris is mixed into the grains to be sorted and recovered, or the grains are However, there is a risk that they are not sorted and collected and are discharged to the outside of the apparatus.

That is, if the time is too long despite the small amount of the remaining processed material, the straw debris leaks through the chaff sieve, and the debris is mixed into the grains to be sorted and collected. In addition, if the time is too short despite the large amount of processed material remaining, the gap will be closed to the minimum value while the grains are not sufficiently sorted and collected, resulting in waste of the grains to be sorted and collected. It was discharged to the outside of the device.

The present invention has been made in view of the above circumstances, and an object thereof is to enable proper selection in a state in which the supply of grain culms to the handling room is stopped.

[Means for solving problems]

The characteristic configuration of the selection control device of the threshing device according to the present invention is a grain culm supply detection for detecting whether or not the grain culm is being supplied to the handling room, while the load detecting means for detecting the threshing load is provided.

It is in the point that
Its action and effect are as follows.

[Action]

That is, the larger the threshing load in the state where the grain culms are supplied to the handling room, the more the amount of processed material remaining in the handling chamber tends to be large, and the grain culm is effectively stored in the handling room. Based on the threshing load in the state of being supplied, by setting the set time for operating the closing control means for the remnants to be longer as the threshing load becomes larger, the closing control means for the remnants, It is operated for a period of time according to the amount of the remaining processed material.

〔The invention's effect〕

Therefore, during the sorting process after the supply of the grain culms to the handling room is stopped, while the closing control means for the remaining substances is operated for an appropriate time according to the amount of the remaining treated substances, It has become possible to properly carry out the process while suppressing the mixing of straw waste into the device and suppressing the wasteful discharge of the grains out of the apparatus.

It is configured to perform preset control in accordance with each time zone (T _{1 to} T ₆ ) while determining which of the sixth time zones (T ₆ ) until the time.

The sixth time period (T ₆ ) is a time period in which so-called pillow threshing may be performed in which the grain culms are manually supplied to the handling room (A).

Ed = E ₀ − (En + Sd) where (En) is the current engine speed.

(Sd) is the travel-down fee and is the travel speed (vehicle speed sensor
It is found by the product of the detection value of (64)) and the set coefficient.

(E ₀ ) is the reference speed, and the stock switch (62) is OF
It is determined by the sum of the engine speed at the time of turning on from F and the running-down allowance.

If a rotation speed higher than the set reference rotation speed (E ₀ ) is detected during automatic control, the high rotation speed is replaced with the reference rotation speed so that the subsequent control operation is performed. I am doing it.

Further, while the first and second set times (t ₁ ) and (t ₂ ) are set and stored in advance to constant values, the third set time (t ₃ ) and the fourth set time (t ₄ ) Is determined by the product of the rotation speed down allowance (Ed) and the set coefficient. That is,
