Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a plant for dry grain preparation for collecting and processing a large number of grains from a large number of producers. In this type of grain plant, grains such as paddy and wheat received from the producer are weighed and then once stored in a storage tank. A plurality of storage tanks are installed, and warm air or normal temperature outside air is supplied from the bottom surface of each tank to predry the grains during storage. However, since the tank has a large capacity, the air is not completely evenly distributed, and grains are likely to be steamed or uneven in dryness.

In order to avoid such quality deterioration during storage,
Conventionally, the whole grain is agitated by appropriately transferring the grain in the tank to another storage tank. Such movement of grain between tanks is called rotation,
The present invention automatically performs this rotation.

[0003]

2. Description of the Related Art Conventional grain rotation determines which of a plurality of grain storage tanks is to be a transfer tank for transferring grains and a squeeze tank for receiving grains in the discharge tanks. Then, a grain conveyor device such as a belt conveyor or an elevator was manually operated to transfer the grains from the discharge tank to the tension tank.

[0004]

[Problems to be Solved by the Invention]
The number of tanks to be rotated is large because the time required for rotation is longer as the tank capacity is larger and the grain amount is larger, and the number of rotations that can be executed at the same time is limited. In this case, it takes a lot of time to complete the whole rotation.

Conventionally, since the grain conveying device is manually operated and the next rotation is executed after one rotation is completed, the operator is required until all the rotations are completed. There was a problem that the efficiency was extremely poor, such as being restrained for a long time and forced to work long hours at night. The present invention solves this problem by providing a rotation system in which the grain storage tanks to be rotated are first set up so that they are automatically rotated in sequence. The first purpose is to release the restraint of workers inside and improve work efficiency.

A second object of the present invention is to reliably detect that a grain is being rotated so that the rotation operation can be performed accurately.

[0007]

The present invention has taken the following technical means in order to solve this problem. That is,
The grain that has been received is stored in a plurality of grain storage tanks, air is blown into the grain storage tanks to pre-dry the grain, and then the grain is finally dried by a dryer in the next step, and the dried grain is removed and sorted and shipped. In the dry preparation facility, among the grain storage tanks, a discharge tank setting switch for setting a discharge tank for discharging the grains in the tank, and a tension tank setting switch for setting a tension tank in which the discharged grains are to be charged, And a rotation setting device that determines the execution order of the rotation for moving the grain in the discharge tank to the loading tank based on the output of the rotation setting device.
A discharge order determination device, and the discharge tank in which the rotation is to be executed from the highest order among the determination orders determined by the rotation order determination device, excluding the combinations that have been completed in rotation. A rotation execution tank determiner for determining a combination of a rotation tank and a squeeze tank, and a grain transfer device for transferring the grain from the discharge tank to the squeeze tank based on the output of the rotation execution tank determiner. A grain sensor that outputs a rotation completion signal to the grain rotation execution tank determiner when there is no grain in the transportation path of the grain transportation device, wherein the grain sensor is the discharge tank. And a lifter for lifting the grain transferred by this grain discharge conveyor.
The automatic grain rotation device is characterized in that it is provided between the grain rotation device and the grain rotation device.

[0008]

By operating the discharge tank setting switch and the expansion tank setting switch of the rotation setting device A, the discharge tank for discharging the grain from the grain storage tank and the discharge grain should be charged. Set up the stake tank. The rotation order determiner B determines the combination of rotations and the execution order. As a result, the combination of the discharge tank for transferring the grain and the squeeze tank is determined, and the execution order of which of the combinations is executed first is determined.

Then, the combination of the tanks of the execution order is excluded from the combination of the rotations already completed, and the combination of the highest order among the remaining combinations is actually set in the rotation execution tank determiner C. decide. Then, according to this determination, the grain in the discharge tank is moved to the tension tank by the grain transport device D.

When there is no grain in the transport path, grain sensor S detects it and outputs a rotation completion signal,
Based on this signal, the rotation execution tank determiner C determines the combination of the next rank as the combination to be rotated. As a result, the rotation is sequentially repeated to transfer the set grains in all the discharge tanks to another tank.
