Description

[Detailed description of the invention] [Industrial application field] In the invention, in a drying facility, the grain conveyed by one elevator is circulated and flown into the main body of the dryer by opening and closing switching operation of a switching shutter to perform a drying operation. The present invention relates to a cereal supply device in a drying facility capable of efficiently performing a storage operation for storing dried cereal or surplus cereal in a storage tank while saving labor.

[Prior Art] Conventionally, a dryer body for ventilation drying while circulating grains and a grain tank for storing surplus grains or dried grains are provided side by side to perform efficient drying or storage operations. A cereal feeder in a drying facility capable of producing the same is known prior to the present application, for example, as described in JP-A-62-288477.

[Problems to be Solved by the Invention] By the way, in the conventional grain drying apparatus of this kind of drying facility, a dedicated elevator is attached to each of the dryer main body and the grain tank, and the grain to be dried is operated by the elevator. It was configured such that it could be supplied so as to be able to circulate and flow into the dryer body, or that excess grains could be temporarily stored.

However, with the above-described configuration, two elevators are required, and the whole apparatus is expensive, or the configuration itself is complicated, and there is a problem that labor saving cannot be achieved.

The present invention has been made in view of the above-mentioned problems of the prior art.
In a drying facility capable of switching supply to a drying tank and a storage tank that are juxtaposed by a lifting machine, in particular, grains remaining during transportation to the storage tank are eliminated and there is no need to perform removal work for that purpose. It is another object of the present invention to provide a grain supply device in a drying facility, in which a storage tank of substantially the same size as a dryer can be installed, and storage efficiency can be reduced and facility costs can be reduced.

[Means for Solving the Problems] In order to achieve the above object, the grain supply device in the drying facility of the present invention is provided with an elevator, and a loading gutter on which a loading conveyor is rotatably mounted at the top is arranged horizontally. In a drying facility, a storage unit having a bottomless transfer gutter laterally provided with a transfer conveyor rotating in a direction opposite to the transfer conveyor of the transfer gutter at the top is provided side by side. On the supply side of the bottomless transfer gutter of the tank, it protrudes outward, and at the top is provided a receptacle facing the discharge part formed in the carry-in gutter of the dryer body, and it is inclined downward on the bottom side. Forming a flow surface, and connecting the connecting end side of the conveying conveyer and the connecting trough in which the front end side of the conveying conveyer is integrally connected to the bottomless conveying gutter and the storage tank with the connecting end side being in an expanded state. Switching formed at the discharge part of the entrance gutter By the operation of the shutter, the supply of grain from the elevator can be switched to the dryer main body and the storage tank.

Further, in the above configuration, a connection portion between the discharge section of the carry-in gutter and the receptacle of the connection gutter is covered with a flexible dustproof cover.

[Operation] When the grain is supplied into the dryer main body and dried by the drying air flowing while the grain is circulating and flowing, the switching shutter is first operated to close the receiving port of the connection gutter, and then the elevator and The conveyor conveyed horizontally in the loading gutter is rotated.
Then, the grain supplied from the elevator to the supply side of the carry-in gutter is transported by the transport conveyer, and is evenly stretched in the dryer main body. When a predetermined amount of cereal is loaded into the dryer body, the supply of the cereal is stopped, and at the same time, the supply of the loaded cereal is circulated through the dryer body via an elevator and dried by the drying air flowing therethrough. I'll let you go.

In addition, when surplus grains or dried grains are stored in the storage tank, the switching shutter is operated to open the receiving port of the connection gutter, and at the same time, the conveyor conveyed horizontally in the bottomless conveyance gutter is rotated, and further imported. Stop the rotation of the conveyor conveyed horizontally in the gutter. Then, the grain supplied from the elevator into the carry-in gutter is supplied from the connection gutter port to the bottomless transfer gutter through the flow-through surface, and is sequentially supplied into the storage tank by the transfer action of the rotating transfer conveyor. At the same time, the storage tank is sequentially stacked and stored from the supply side of the storage tank toward the transport direction.

Therefore, if the stored grain is reduced due to the action of discharging the grain stored in the storage tank, the grain supplied from the connection gutter and the bottomless transfer gutter via the elevator sequentially flows down from the supply side of the storage tank and is always full. Some of the grains supplied from the discharge unit are transported from the bottomless transport gutter to the storage tank by the transport conveyor arranged in the connecting gutter, and the other part is Thus, it is supplied directly to the storage tank and can be prevented from remaining in the connection gutter or the transport gutter.
