Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an O-
Standard constant surface 1fjK without being affected by wear etc.
Regarding the deweighing rate control bag tltK, which maintains the deweighing rate of paddy and brown rice at a constant level by adjusting and maintaining tK, is the drive w+ or drive u1 of the sharp stirring roll interrupted? The automatic and manual roll gap adjusting means is equipped with a roll rotation detecting member for detecting, and when the detecting member detects a disturbance interrupter of the agitation roll, it completely disables the gap adjustment of the weighing roll. Regardless of the situation, the rotation of the sharp roll may be interrupted and the roll gap adjustment may become impossible. It is an object of the present invention to provide an IBP agitation rate control device for an unhulled rice huller, which enables accurate constant control of the unweighing rate over the entire length.

The circuit f731 is configured to detect it.

The wooden frame example has the above-mentioned structure, and the gap (C) of sharp roll +31 +41? By maintaining a constant state of starvation, the mixing ratio of paddy and mixed rice with a sharp spoon and the stirring rate?

C1 maintains proper clearance.

Now, when the ratio of mixed rice between the rolls (m (C1 expands due to wear of rolls +31 + 41, etc. and its sharpness decreases) and the mixed rice ratio increases, the flow rate of mixed rice from the outlet (431) decreases, The impact load hitting the receiving plate @ηKtI also becomes smaller, and the four forces change the driving lever γ-pot;

%), and even in this case, as long as the one-motor stirring roll f3H41 is not being driven, the roll gap (0) will not be adjusted.As a result, the roll gap will be zero. During the alignment, the removal rolls +31 and +41 were in contact with each other, and the removal rolls f31ii were driven and licked, so the contact sound was transmitted to the microphone (6ω
This eliminates the inconvenience of abnormally reducing the roll gap CO due to the inability to detect it, and as described above, it is possible to prevent damage to the demolition control system such as the sharp motor (7).

As is clear from the above embodiments, the present invention provides a structure in which the sharpness of paddy and brown rice is constantly controlled by the same @ (C) control of a pair of dehulling rolls + 31 + 41.
A roll rotation detection unit U (741 is provided for detecting drive vJ or drive interruption of 31+41, and when the detection unit 41 (74+ detects the interruption of the removal roll +31 +41), the gap between the removal roll +31 +41 is detected. Regardless of automatic and manual roll gap ICI adjustment means, the IJ adjustment is rendered inoperable.
Whenever the rotation of rolls +31 and +41 is interrupted, this roll gap [C1 adjustment can be disabled,
It is possible to protect the roll gap adjustment mechanism by preventing overloading of the roll gap adjustment motor (7), and as a result, it is possible to perform accurate unweighing rate control over a long period of time. It has remarkable effects such as being able to improve its performance.
