[0003]

[Problems to be Solved by the Invention] The raw rice was put into the hot air drying device of the grain dryer, and an attempt was made to start single drying by setting a single pad. Grains are, for example, placed in a cooling device, and the remaining grains are dried in a standing state in the cooling device while being cooled and dried, while on the other hand, grains that are placed in the hot-air drying device. The grains are dried by being exposed to hot air while being circulated in the hot air drying device, and the dried grain is dried by the hot air drying device if the cooling device is empty. It is transferred to the device and is allowed to cool in this cooling device in a stationary state.

During this series of operations, the remaining grains are loaded into the cooling device in the preceding stage and the dried grains are transferred from the hot air drying device to the place during standing and cooling by mistake. When the rice was supplied as a mixture, the raw grain of the residual grain and the dried grain were sometimes mixed with each other. This is to prevent this mixing.

For a certain work operation, even if a driving operation is performed, the operation input is not accepted. A configuration of the rolling control system.

[0006]

[Advantages of the Invention] The raw rice was put into the hot air drying device 2 of the grain dryer, and an attempt was made to start single drying by setting a single pad. ,
For example, while the grains are drawn into the cooling device 1 and the remaining grains are allowed to cool and dry in the cooling device 1 in a stationary state, on the other hand, the grains that are drawn into the hot air drying device 2 Is dried by being exposed to hot air while circulating in the hot air drying device 2, and the dried grain after drying is released from the hot air drying device 2 if the cooling device 1 is empty. The grains are moved and supplied to the cooling device 1, and the grains are allowed to cool in the cooling device 1 in a stationary state.

During this series of operations, the determination means determines the presence / absence of grains in the cooling device 1 and the hot-air drying device 2 and the determination of raw paddy or dry paddy. According to the determination result, the additional feeding of the grain and the movement of the grain from the cooling device 1 to the hot-air drying device 2 or, conversely to the above, the grain from the hot-air drying device 2 to the cooling device 1 is performed. In the moving driving work that moves, for the moving driving work in which raw paddy and dry paddy may be mixed, even when the driving operation is performed, the input of this driving operation is not accepted, and therefore the grain Mobile driving work is not performed.

[0008]

According to the present invention, both the presence / absence of grains in the cooling device 1 and the hot-air drying device 2 and the determination as to whether or not raw paddy or dried paddy are performed are carried out. Regarding the operation of moving the grain that may be mixed with dry paddy, even if the operation of starting this operation is performed, the input of this operation is not accepted, so the operation of moving the grain is not started. Therefore, the raw rice and the dry rice are not mixed with each other, and the good grain can be dried.
