[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air generator for a grain dryer.

[0002]

2. Description of the Related Art Conventionally, a grain is generated from a burner while being circulated from a grain storage chamber to a grain drying chamber by rotationally driving a feeding valve and flowing down a downflow shelf to be supplied to a grain collecting trough. The generated hot air passes through the hot air passage chamber formed by the hot air passage chamber cover, passes through the air blowing chamber, and passes through the drying chamber, so that the hot air is exposed to the hot air and dried. The burner is configured so that it does not move inside the machine wall below the falling shelf by means of bolts and nuts, and the hot air passage chamber cover is also fixed to the machine wall by means of bolts and nuts. It was a generator.

[0003]

The grains stored in the grain storage chamber of the grain dryer are fed from the storage chamber into the grain drying chamber by the rotation drive of the feeding valve, and flow down the flow-down shelf. The hot air generated from the burner passes through the drying chamber from the hot air passage chamber through the air blowing chamber while being supplied to the grain collecting gutter and circulated, so that the grains flowing down in the drying chamber are exposed to the hot air. And dried.

If a problem occurs in the burner during the drying operation, the bolts and nuts fixing the hot air passage chamber cover are removed, and the hot air passage chamber cover is removed. Remove the bolts and nuts that secure the burner provided in the machine wall, remove the burner, and perform repairs and inspections, and then install the burner and hot air passage chamber cover again. It is difficult to remove and install the device because it is inside the machine wall, and it took a long time to install and remove the device.

[0005]

According to the present invention, grains are fed from an upper grain storage chamber 8 to a lower grain drying chamber 9 by rotationally driving a feeding valve 12 and flowed from a downflow shelf 14 to a grain collecting trough 13. In the grain drying machine, the hot air generated from the burner 3 is allowed to flow from the hot air passage chamber 16 formed by the hot air passage chamber cover 15 to the drying chamber 9 through the air blowing chamber 11 to dry the hot air generated by the burner 3 and the burner 3. The burner 3 is integrally connected to the hot air passage chamber cover 15 of the hot air passage chamber 16 by a connecting member 27.
The hot-air passage chamber cover 15 and the hot-air passage chamber cover 15 are provided below the falling shelf 14 along the holding frame 17 so as to be movable in the front-rear direction.

[0006]

The grains stored in the grain storage chamber 8 of the grain dryer are fed from the storage chamber 8 through the grain drying chamber 9 by the rotation drive of the feeding valve 12, and the falling shelves 14 are fed. While flowing down and being supplied to the grain collecting trough 13 and being circulated, the hot air generated from the burner 3 passes through the drying chamber 9 from the hot air passage chamber 16 through the air blowing chamber 11 to pass through the drying chamber 9.
The grains flowing down inside are exposed and dried.

If a problem occurs in the burner 3 during the drying operation, the burner 3 is integrally connected by the connecting member 27 held by the holding frame 17 in the machine wall below the downflow shelf 14. The hot-air passage chamber cover 15 and the hot-air passage chamber cover 15 are slid forward along the holding frame 17, removed from the holding frame 17, repaired and inspected, and then moved backward along the holding frame 17. Then, the hot air passage chamber cover 15 is fixed by bolts and nuts.

[0008]

According to the present invention, the hot air passage chamber cover 15 is provided.
The burner 3 and the burner 3 are integrally connected by the connecting member 27. Further, both the hot air passage chamber cover 15 and the burner 3 which are connected to each other are held by the holding frame 17 and are slidably moved. Also, it is easy and easy to remove, and the installation and removal can be done in a short time.
