Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain switching device for a grain dryer.

Conventional technology In the past, grains were sequentially fed out from the grain storage chamber into the grain drying chamber and into the lower grain collecting trough, and were then fed into the grain hoist using a lower grain collecting spiral installed in the lower grain collecting trough. While the circulation is repeated, the hot air from the hot air device is ventilated into the drying room and sucked and exhausted by the exhaust fan. By blowing air, the grains flowing down in this drying chamber are exposed to this hot air and dried, and then the grains are transported from the cooling chamber to the upper grain collecting trough, the storage chamber, the drying chamber, and the lower part. The grain is sequentially fed out into the grain collection gutter, and is transferred and supplied into the grain hoist by the lower grain collection spiral in the lower grain gutter, and is conveyed to the upper part by this hoist to the upper part of the feed funnel. While the circulation of the hot air supplied into the cooling chamber is repeated, the hot air from the hot air device is ventilated into the drying chamber and is sucked and exhausted by an exhaust fan, thereby removing the grains flowing down the drying chamber. This is a configuration in which either one of double drying, which is drying by exposure to hot air, is performed.

During the circulation drying of the grains by this single drying, the grain circulation drying operation and the tensioning operation of tensioning the grains into the cooling chamber from the tensioning device installed at the upper part of the cooling chamber. This was a grain dryer that did not have a special grain switching device that performs switching control to perform both simultaneously □ Problem to be solved by the invention When grains are dried by single drying, the grain dryer The grains stored in the grain storage chamber are sequentially fed out from the storage chamber into the grain drying room and into the lower grain collecting trough, and are transferred and supplied from the lower grain collecting trough to the grain hoisting machine by the lower grain collecting spiral. The grain is transported to the upper part of the grain raising machine and fed into the storage chamber through the supply funnel while the circulation is repeated.
The hot air generated from the hot air device passes through this drying chamber and is sucked and exhausted by an exhaust fan, so that the grains flowing down within this drying chamber are exposed to this hot air and dried.

During this circulation drying operation, when performing a tensioning operation in which grains are passed from the tensioning device into the cooling chamber, the circulation drying operation is temporarily stopped, the tensioning device is started, and the tensioning device is The grains fed from 5 are fed into the cooling room through the feed funnel. When this work of putting grain into the cooling chamber is completed, the putting device is stopped and the circulation drying work is started again.

The purpose is to force the grain into the cooling chamber using the feeding device without stopping this circulation drying operation.

Means for Solving the Problems This invention moves grain from an upper cooling chamber 1 to a lower upper grain collecting trough 2, a grain storage chamber 3, a grain drying chamber 4. and lower grain collection trough 5
The grain is sequentially flowed down into the lower grain collection trough 5 and transferred to a grain hoist 7 by the grain hoist 7, transported to the upper part by the hoist 7, passed through a supply funnel 8, and then released. While the circulation of supplying hot air into the cold room 1 is repeated, the hot air from the hot air device 9 is supplied to the drying room 4.
The air is sucked and discharged by an exhaust fan 10 to dry the grains. In a grain dryer equipped with a bottom plate 12 that can be opened and closed to switch between flowing down into the storage chamber 3, a loading device 13 for loading grain is provided on the upper side of the dryer, and a note is placed inside the supply funnel 8. Staking device 1
3 and circulating grains transported and circulated by the grain raising machine 7 are separately supplied to the cooling chamber 1 and the storage chamber 3. The structure of the grain switching device is characterized in that a valve 14 is provided.

Effect of the Invention When grains are dried by single drying, the grains stored in the grain storage chamber 3 of the grain dryer are transferred from this storage chamber 3 to the grain drying chamber 4 and the lower grain collecting trough 5. From this lower grain collecting trough 5, the grain is transferred and supplied into the grain raising machine 7 by the lower grain collecting spiral 6, and is conveyed to the upper part by this grain raising machine 7, and is passed through the switching valve in the supply funnel 8. By switching operation of 14 to the side where grains are supplied into the storage chamber 3, the circulation of supplying grains into the storage chamber 3 through the supply funnel 8 is repeated while the hot air is generated from the hot air device 9. The hot air is in this drying room 4.
The grains flowing down the drying chamber 4 are exposed to this hot air and dried by being sucked and exhausted by the exhaust fan IO, and when the grain moisture reaches the finishing target moisture, the drying process is completed. The machine is automatically controlled to stop drying the grains.

During this drying operation, when carrying out a tensioning operation in which the grains from the tensioning device 13 are introduced into the cooling room 1, the supply funnel 8 is
The grain conveyed to the upper part by the grain raising machine 7 is supplied into the storage chamber 3 through the switching valve 14 in the interior, and the grain from the tensioning device 13 is supplied into the cooling chamber 1. By switching to the side where the grains are transferred, the grains transferred by the tensioning device 13 are tensioned from the tensioning device 13 into the cooling chamber 1, and are transferred to the storage chamber 3 in the same manner as described above. The grains inside continue to be circulated and dried, and when the tensioning operation is completed, the tensioning device 13 is controlled to stop.

Effects of the Invention According to the present invention, when the grains in the grain storage chamber 3 are being circulated and dried, for example, if the remaining grains are left as they are because they could not be pushed into the storage chamber 3, the grains are removed. The grains leak and the quality deteriorates, but in such a case, the remaining grains can be stretched into the cooling chamber 1 by switching the switching valve 14 in the supply funnel 8 without stopping the circulation drying operation. The operation is simple and the grains can be stored in this cooling chamber 1.
By performing ventilation drying inside the container, it was possible to prevent the grains from becoming stuffy, thereby preventing deterioration in the quality of the grains.
