Description

[Detailed description of the invention] Industrial i1m field This invention relates to a grain dryer.

Conventional technology Conventionally, grains are fed out from a storage chamber by rotating a feeding valve, which is a drying chamber provided in the front and rear directions, and are allowed to flow down into a grain collection chamber provided in the front and rear directions below this feed valve. It was a device that transferred the grain to one side using a provided transfer helix and discharged it into the hoisting machine.・Problem to be solved by the invention Grain is fed from the upper storage chamber to the lower drying chamber by rotation of a feeding valve, flows down into the grain collecting chamber at the bottom of this feeding valve, and is provided in the grain collecting chamber. It is transferred to the second side by a transfer helix and discharged into the shell elevating machine, and transported to the upper part by this shell elevating machine, and while repeating diffusion and reduction into the storage chamber, the hot air generated by the burner is ventilated and exhausted from the drying chamber. In a dryer in which air is suctioned and exhausted by a wind machine and the grains flowing down the drying chamber are exposed to this hot air and dried, the grains fed out by the feeding valve, when flowing down the grain collection room, If the inclination angle of this grain collection room is not at a predetermined angle or more, the grains will stagnate and not flow down when the moisture content is high. Therefore, this inclination angle must be set to a steep inclination angle. If the setting is set to may decrease.

Means for Solving the Problems This invention provides a storage chamber (2) in the upper part of the model (1) and a plurality of drying chambers (3) in the lower part in the front and back direction. ) At the bottom, the grains are stored in the storage chamber (2) by rotation.
A spiral (4) and a transfer gutter (5) are provided respectively for feeding out the drying chamber (3) and transferring it to one side, and a burner (6) is provided.
The hot air generated by the drying chamber (3) is cross-ventilated to be suctioned and exhausted by an exhaust fan (7), and the model (1)
A helical (8) and a transfer gutter (9) are provided in the left and right direction at the lower part of the front surface, and a helical (4) is provided at the upper part of the helical (8) and transfer gutter (9).
) The terminal end of the transfer gutter (5) is configured to communicate with the terminal end of the helix (8), and the terminal end of the transfer gutter (9) is configured to communicate with the grain raising machine (1G) that conveys the grains to the upper part. The structure of the grain dryer is as follows.

Functions and Effects of the Invention The grains housed in the model (1) are fed out from the storage chamber (2) through the lower multi-row drying chamber (3) by the rotation of the helix (4) and flowed down the transfer gutter. (5) The inside is transferred to one side and discharged into the helix (8) transfer gutter (9), this helix (8) is discharged through the transfer gutter (9) into the grain raising machine (10), and this The grain is conveyed to the upper part by the hoisting machine (10) and is repeatedly circulated and returned to the storage chamber (2), while the hot air generated from the burner (6) is passed through the drying chamber (3). 3) The grains flowing down inside are exposed to this hot air and dried.

Conventionally, grains are fed out from the drying chamber (3) by rotation of a feeding valve, flowed down into a grain collecting chamber, and collected therein,
The grain was transferred to one side by a transfer helix in the collecting chamber, discharged into the grain elevator (10), and transported to the upper part by the grain elevator (10) for circulation drying. According to the invention, the grains are transferred from the drying chamber (3) at the same time as they are fed out by the rotation of the helix (4), and transferred to the helix (8) and the transfer gutter (9).
This helix (8) transfer gutter (9) transfers the grain I
