Description

[Detailed description of the invention] Industrial applications This invention relates to a grain dryer.

Conventional technology In the past, a storage chamber was provided in the upper part of the machine wall, and a plurality of drying chambers were provided in the lower part in the vertical direction.4 A feeding valve was provided in the lower part of this drying chamber, and grain was removed from the drying chamber. The grains collected in the grain collection chamber are transferred and discharged by the transfer helix into the grain raising machine, and the grains collected in the grain collection chamber are transferred and discharged by the grain raising machine. This device dried the grains by transporting them to the upper part and repeating circulation and return into the storage chamber, and then passing hot air generated from a burner into the drying chamber.

Problems to be Solved by the Invention Grain is fed out and flowed down from a storage chamber in the upper part of the machine wall into a drying chamber provided vertically in the lower part by rotating a feed valve, and hot air generated from a burner is passed through the drying chamber. The grains flowing down in this drying chamber are exposed to this hot air and dried, transferred and discharged into a grain hoist using a transfer helix, and then repeatedly circulated and returned to the storage chamber by this hoist to dry them. In the dryer,
Since the storage chamber and the drying chamber are configured to communicate vertically within the machine wall, the capacity of the storage chamber is small;
The amount of grain that can be stored in this storage chamber is small, and in order to increase the storage capacity, the total height of the dryer must be increased, and the grains flowing down the inner wall plate of the machine wall have a large flow resistance. , circulation spots may occur and the grains may become patchy dry.

Means for Solving the Problems This invention provides a storage chamber (2) in the upper part of a box-shaped machine wall (1) for storing grains, and a storage chamber (2) in the upper part of this storage chamber (2). Spiral (3) for transferring grain into the chamber (2)
A transfer gutter (4) is provided in the front-rear direction, and at the bottom of this storage chamber (2) there is a spiral (5) transfer gutter (5) that moves back and forth within this storage chamber (2) to feed out the grains and transfer them to one side. 6) are provided in the left and right direction, and the helix (5), the transfer gutter (8) which receives the grains to be transferred by the transfer gutter (6) and transfers them to one side, is connected to the machine wall (1) on one side. This helix (7
) A burner (9) is installed at the bottom of the transfer gutter (8),
A cylindrical drying device (lO) is installed on one side of the machine wall (1) to dry the grains while conveying them to the top.
10) Inside the cylinder, ventilation mesh plates (11), (11) are used to divide the cylinder into three layers, and the inner ventilation mesh plate (11) is provided with a helix (12) on its outer periphery so that it can rotate freely. A ventilation chamber (13) is formed on the outside of these three rooms, a hot air chamber (14) is formed on the inside, and the hot air chamber (14) and this ventilation chamber (13) are connected to each other. A drying chamber (15) is formed between them, and the helical (3) transfer gutter (
4) to communicate with each other, and the helix (7) and the transfer gutter (8) are connected at the lower end.
The burner (9) is connected to the lower end of the hot air chamber (14).
The grain dryer has a structure in which an exhaust fan (16) is provided on the outer wall panel forming the ventilation chamber (13), and the grain dryer is configured to communicate with the ventilation chamber (13). .

Effects of the invention The grains accommodated in the machine W (1) do not move back and forth, but are fed out and transferred from the storage chamber (2) by the rotation of the helix (5). The transfer gutter (6) is used to transfer and supply the spiral (7) into the transfer gutter (8).
) is transferred through the transfer gutter (8) into the drying chamber (15) of the drying device (10), and while being transferred within this drying chamber (5) by the rotation of the helix (12), the burner (
9) By sucking the hot air generated by the exhaust air 41 (1B), the hot air is passed from the hot air chamber (14) of the drying device (10) to the drying chamber (15) through the exhaust chamber (13). The grains, which are sucked and exhausted by the exhaust air Ia (te) and are being transferred to the upper part in the drying chamber (15), are exposed to this hot air and dried, and then transferred from the drying chamber (15) to the helical (3) transfer gutter. (4), and by the rotation of this helix (3), the transfer gutter (4)
While being transferred inside, the grains leak into the storage chamber (2) and are dried through repeated circulation.

Conventionally, grains are fed out and flowed down from the storage chamber (2) in the upper part of the machine wall (1) to the drying chamber (15) in the lower part by rotating a delivery valve, and the grains are raised by a transfer helix in the grain collecting room. The grain is transferred and discharged into the machine, and is repeatedly circulated and returned to the storage chamber (2) by the grain raising machine, and the hot air generated from the burner (9) is passed through the drying chamber (15) to dry the grain. There was, but
