Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is an improvement of a grain dryer, particularly a dryer having a plurality of air supply gutters and exhaust gutters extending laterally in a grain drying chamber. It is about.

(Prior Art) A conventional dryer has a grain drying chamber in which a plurality of air supply gutters and exhaust gutters whose bottom surfaces are open are laterally extended from one side wall to a wall opposite to each other. The gutter was connected to the air supply hood through an opening formed in the one side wall, and the exhaust gutter was connected to the exhaust hood through an opening formed in the opposite wall.

Then, when the grain is put into the grain drying chamber and the dry air is sent from the air supply hood by the blower, the air flows into the air supply trough through the opening from the air supply hood, and the grain is discharged from the opening of the air supply trough. It passed through the formations into the exhaust gutter, where it was released to the atmosphere through the exhaust hood. (Actual development
59-133992 publication).

(Problems to be solved by the invention) The conventional dryer has two problems. First, since air is fed from one side of the grain drying chamber to the other side, it does not overflow evenly from the opening edge of the lower side of the air supply gutter, but it overflows near the opening of the exhaust gutter (shortcut), It was supposed that there would be a part in the grain layer where air was not passed. Secondly, the air supply hood and the exhaust hood are located on the outer walls of the grain drying chamber which face each other, thus taking up an installation space.

SUMMARY OF THE INVENTION The present invention provides a dryer that does not need a shortcut for air supply while the space occupied by a conventional air supply hood is sufficient.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides:
A plurality of air supply gutters and exhaust gutters whose bottom surfaces are open are extended laterally from the one side wall to the opposite wall, and the air supply gutter and the exhaust gutter have openings formed in the one side wall. The air supply gutter and the exhaust gutter are connected to the air supply hood and the exhaust hood, respectively.

(Operation) With the above configuration, air is fed from the air supply hood into the grain drying chamber through the air supply gutter. The air in the supply trough overflows from the opening on the lower surface, passes through the grain layer and flows into the nearest exhaust trough, and then is exhausted through the exhaust hood.
Both the air supply gutter and the exhaust gutter have openings on the same side wall side, and the air supply gutter overflows at a part far from the opening, so there is no shortcut, and there is an air supply hood and an exhaust hood on one side of the grain drying chamber. Since it is located, the area occupied by the device can be reduced.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The grain drying chamber 1 is a substantially prismatic chamber, and although not shown in the drawing, a grain feeding device is attached to the upper portion, and a lower portion is provided with a hopper-shaped discharge port 2.

In the grain drying chamber 1, from one side wall 1a to the opposite wall 1b,
A plurality of air supply gutters 3 and exhaust gutters 4 whose lower surfaces are open are extended in the lateral direction. A plurality of air supply gutters 3 are aligned at appropriate intervals in the vertical direction, and are also aligned at appropriate intervals in the horizontal direction. The exhaust gutters 4 are also vertically aligned at appropriate intervals and are located between the rows of the supply gutters 3. Both the supply gutter 3 and the exhaust gutter 4 have a triangular cross section and an open lower surface. The lower edge of the supply gutter 3 is inclined so that the side close to the opening is located downward, and the lower edge of the exhaust gutter 4 is inclined so as to be opposite.

The air supply gutter 3 and the exhaust gutter 4 are in close contact with each other on the side of the opposing wall 1b, but their side walls 1a are connected to the triangular openings 5, 5'provided on the side walls 1a, respectively.

One side wall 1a of the grain drying chamber 1 is covered with a hood 8 having an air supply port 6 in the lower part and an exhaust port 7 in the upper part. Inside the hood 8, an opening 5 communicating with the air supply gutter 3 and an opening 5 ′ communicating with the exhaust gutter 4 are vertically divided by a meandering partition wall 9 to form an air supply zone 10 and an exhaust zone 11.

Install an intake fan at the air supply port 6 or an intake fan at the exhaust port 7. Also, both may be attached respectively.

The operation of the embodiment will be described below.

The dry air entering from the air supply port 6 passes through the air supply zone 10,
The grain layer filled in the grain drying chamber 1 flows into the air supply trough 3 through the opening 5 leading to the air supply trough 3, advances to the vicinity of the tip, and overflows from the lower edge of the air supply trough 3, In particular, it flows into the grain layer located above the supply gutter 3 to dry the grain.
After that, the air in the grain layer is exhausted above the exhaust gutter 4
Flows toward the connected opening 5 ', reaches the exhaust zone 11 through the opening 5', and is discharged from the exhaust hole 7.

Since the apparatus is installed in the facility as shown in FIG. 3, since the hood is attached only to one side of the grain drying chamber 1, it can be installed in a space smaller than the conventional one. On the other hand, the conventional apparatus has an air supply hood 8'and an exhaust hood 8 "on opposite sides of the drying chamber 1 ', as shown in FIG.

(Effect) Since the present invention has the above-mentioned structure, the air entered from the air supply gutter can dry the grain without short-cutting, which is efficient and is only supplied to one side of the drying chamber. Since the hood is provided, the installation space of the device can be made smaller than the conventional one.
