Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower chamber device for a grain dryer.

[0002]

2. Description of the Related Art Conventionally, a plurality of rows of grain drying chambers formed between grain storage chambers and grain drying chambers are rotated by a feeding valve so that the grains are fed from a hot air device while being circulated. The generated dry air passes through the air blowing chambers formed between the drying chambers and passes through the drying chambers, so that the circulating grains are exposed to the drying air and dried.

Dust and the like falling from the drying net during the drying work is accumulated on the bottom plate of the blower chamber. To clean the accumulated dust, remove the cleaning lid provided above the cleaning port of the bottom plate. The blower chamber device is a system in which the dust is dropped to the lower part through the cleaning port to clean the dust.

[0004]

The grains stored in the grain storage chamber of the grain dryer are driven to rotate the feeding valves from the storage chamber to the grain drying chambers formed between the grain drying nets. Thus, while being fed down and circulated, the dry air generated from the hot air device passes through the drying chamber through the air blowing chamber formed between the drying chambers, so that the circulating grains are exposed to this drying air. And dried.

The dust dropped from the drying net during the drying operation is accumulated on the bottom plate of the blower chamber. When removing the accumulated dust for cleaning, the dust is provided above the cleaning port of the bottom plate. Remove the cleaning lid and drop the dust from the cleaning port to the bottom to clean. In addition to facilitating the cleaning, the reinforcement of the lower part of the drying net is simplified and the cost is reduced.

[0006]

According to the present invention, the feeding valve 13 is rotationally driven from the upper grain storage chamber 8 to the plural grain drying chambers 9 formed between the lower grain drying nets 10, 10. It is provided so as to ventilate the drying air generated from the hot air device 4 to the drying chamber 9 through the air blowing chamber 12 formed between the drying chambers 9 and 9 to the drying chamber 9 while letting the grains flow out. 12
At the left and right ends of the bottom plate 16 of the base plate 16, guide portions 17, 17 for guiding the grain in the front-rear direction are provided so as to be inclined downward, and an opening 18 is provided in a predetermined width in the front-rear direction. A receiving guide portion 21a is formed at one end of each of the left and right sides of the portion 18 with an inclined portion 20 that is inclined further inward from a vertical portion 19a that is bent downward in the front-rear direction.
And a receiving guide portion 21b that forms a vertical portion 19b that is bent downward in the front-rear direction at the other end, and the opening 18 is a box-shaped opening / closing that can be opened and closed in the vertical direction. The valve 22 is provided so as to be axially supported, one side wall portion 23a of the opening / closing valve 22 is joined to the vertical portion 19a of the receiving guide portion 21a, and the other side wall portion 23b is bent downward in the lateral direction. The bent portion 24 is joined to the lower end edge 26 of the vertical portion 19b of the receiving guide portion 21b to constitute a blower chamber device of a grain dryer.

[0007]

The dry air generated from the air passes through the drying chambers 9 through the air blowing chambers 12 formed between the drying chambers 9 and 9,
The circulating grains are exposed to this drying air to be dried, and when the finishing target moisture is reached, it is determined that the drying is completed, the dryer is automatically stopped and controlled, and the drying of the grains is stopped.

The dust dropped from each drying net 10 during the drying operation is accumulated on the left and right side portions of the bottom plate 16 of the blower chamber 12 and on the open / close valve 22. When removing the accumulated dust, The on-off valve 22 provided in the opening 18 of the bottom plate 16
From the center of rotation, the bent portion 24 below the side wall portion 23b of the on-off valve 22 is rotated downward to rotate the side wall portion 23a upward, and the dust accumulated on the on-off valve 22 is Dust that flows down on the on-off valve 22 and drops from the opening 18 to the lower portion, and dust accumulated on both left and right sides of the bottom plate 16 drops from the opening 18 to the lower portion to be cleaned.

[0009]

According to the present invention, the bottom plate 16 of the blower chamber 12 is
By rotating the opening / closing valve 22 provided in the opening 18 of the opening / closing valve, dust accumulated on the opening / closing valve 22 is dropped and can be cleaned easily, and the left and right side portions of the bottom plate 16 can be easily cleaned. By providing the guide parts 17 and 17,
Since the lower portions of the grain drying nets 10 and 10 can be attached to the guide portions 17 and 17, the drying nets 10 and 10 can be attached.
The reinforcement can be simplified and the cost can be reduced, and the assembling of the drying nets 10 can be facilitated.
