Description

[Detailed description of the invention] The present invention relates to a control device for a rice huller sorting machine.

In conventional rice hulling sorting machines, each drive part starts or stops at the same time, so if it stops in the middle of work, when it restarts, the drive motor will be overloaded by the grain remaining in each part. There was a risk of damage due to rusting, or if a swallow was installed as a grain lifting machine, the wings could be damaged. Furthermore, in order to prevent such accidents, it was necessary to continue operation for a while after stopping the supply of paddy to ensure that most of the grain remaining in various parts of the machine was discharged. Therefore, the amount of grain on the oscillating selection plate decreases and the sorting condition differs from that during normal operation, so when restarting the machine, it is necessary to adjust the grain removal section again, such as adjusting the partition plate, etc. It was.

In addition, a level meter is installed in each of the paddy tank and mixed rice tank, and the shutter of the paddy tank is automatically opened and closed based on the detection signal from the level meter of the paddy tank, and the shutter of the paddy tank is automatically opened and closed based on the detection signal from the level meter of the mixed rice tank. An automatic control device for a hulling grain sorting plant that controls the flow rate balance of grain by operating a swinging sorter has been proposed as Japanese Patent Application Laid-Open No. 130157/1983. It adjusts the flow rate balance of the grains being transported on a regular basis, and uses the detection signals from the level meters installed in the paddy tank and mixed rice tank as the command source, so it is used at the startup of the hulling grain selection plant and It is not possible to deal with residue when the grain supply is stopped, and the opening and closing of each shutter is restricted to a predetermined sequence of operations, so the timing of starting and stopping grain feeding cannot be arbitrarily selected. It was something that I couldn't do.

The first object of the present invention is to eliminate the above-mentioned drawbacks, and when the machine is stopped in the middle of work, the grains inside the machine are moved to a part where there is no problem in restarting the machine, thereby eliminating the risk of an accident. First, it is an object of the present invention to provide a control device for a rice hulling sorter that can save energy by stopping only the swing sorting device.

A second object of the present invention, in addition to the first object, is to discharge the grains by opening the bottom plate of the equalizer when the oscillating sorting device is stopped. It is an object of the present invention to provide a control device for a rice huller sorting machine that is simplified.

In addition to the object of the second invention, the third object of the present invention is to receive and store the grains discharged from the opening/closing bottom plate of the equalizer in an adjustment tank, and to reuse the grains when the machine is operated.
