Description

[Detailed Description of the Invention] The present invention relates to a grain feeding device in a grain drying device.

FIG. 1 shows a transfer supply trough attached to the drying device.

A conventionally known supply gutter A has a screw conveyor B therein, a supply port C at one end, and a plurality of drop ports E provided on the lower surface in the length direction.

In this known example, when grains are introduced through a supply port C and transported laterally by a screw conveyor B, the same amount of grains falls from each drop port E.

However, in the known example shown in FIG. 1, when a large amount of grain is input from the supply port C, most of the grains advance to the drop port E, resulting in a difference in the amount of falling between the drop port and the drop port E.

The solutions shown in Figures 2 and 3 solve this problem using simple means.

That is, 1 is a supply gutter, inside which a screw conveyor 2 is mounted, a supply port 3 is provided at one end, and a plurality of drop ports 4 and 5 are provided on the lower surface in the transfer direction.

In this case, the drop port 4 on the side closer to the supply port 3 has its bottom surface 6
A small-volume drop port 9 with a small area is opened on the side surface 7, and a large-volume drop port 8 with a large area is opened on the side surface 7, so that when the supply gutter 1 transports at its maximum, exactly half of the amount falls from the large-volume drop port 8, It is only necessary to configure the structure so that half of the amount falls from the drop port 5.

3 is a sectional view taken along line A-A, FIG. 4 is a sectional view taken along line B-B, and FIG. When the amount of grains is small, the small-area drop port 9 with a small area acts, and when the amount of grains is large, the large-area drop port 8 with a large area acts as shown in Figure 6, regardless of the size of the grain amount. First, half of the grain is always dropped from the drop port 4, so that it is supplied into the humidity control tank 10 on average.

FIG. 7 shows an example in which the devices shown in FIGS. 2 to 6 are incorporated into a humidity control type grain drying apparatus, where 10 is a humidity control tank having a rectangular planar shape; 11 is a humidity control tank 10; The downstream drying section 11 is provided with a hot air supply chamber 12 in the center, and downstream drying chambers on both sides of the hot air supply chamber 12, as shown in FIG. 13.13
', and hot air exhaust chambers 14, 14' are provided further outside of the downstream drying chamber 13.13'.
A suction machine 15 is attached to 14', and a furnace is attached to the hot air supply chamber 12.

A rotary valve 16.16' is attached to the lower end of the downstream drying chamber 13.13'.
A grain collection room 17 is provided so as to surround the grain collection room 16', a screw conveyor 18 is installed horizontally in the center of the grain collection room 17, and an end of the screw conveyor 18 is connected to a lower end of an elevator 19.

The elevator 19 includes a humidity control tank 10 and a downstream drying section 1.
Therefore, the supply port 3 is formed near one side of the humidity control tank 10, and the supply gutter 1 connected to the supply port 3 is installed horizontally at the top of the humidity control tank 10. will be established.

Next, we will discuss the effect.

When starting work, raw materials are supplied to the humidity control tank 10 to fill the humidity control tank 10, but in this case, the raw materials are not being dried, but simply being poured, so it is necessary to feed the raw materials slowly. It is better to supply it quickly rather than in a hurry.

Therefore, a large amount of raw material is fed into the elevator and fried one after another, and a large amount of the raw material is flown into the feed port 3.

At that time, a large amount of grain is fed into the feed gutter 1, so the inside of the feed gutter 1 becomes as shown in FIG. The remaining half of the amount that falls from the bulk drop port 8 opened at the side surface 7 as well as the volume drop port 9 is subsequently transferred and falls from the drop port 5 opened at the tip of the supply gutter 1.

(The number of the drop ports 4 and 5 is not limited to two.

If the number is increased, the opening area of each droplet should be determined to be - the number of droplets.)

Thus, inside the humidity control tank 10 and the down-flow drying chamber 13.1
3' will be filled with grain on average.

Once the grain filling is completed, circulation drying is carried out, but during circulation drying, only a small amount of the grain fed out by the rotary valve 16, 16' is fried.

Therefore, the grains fed into the feed gutter 1 are as shown in FIG.
Since the small amount does not reach the large-volume drop port 8 opened on the side surface 7, it falls only through the small-volume drop port 9 with a small area, and the remaining amount falls from the drop port 5 at the tip.

The present invention has the above-mentioned configuration, and has a humidity control tank 10 at the top.
A down-flow drying section 11 is provided at the bottom, a feeding/circulating elevator is provided on the side, and a supply gutter 1 containing a screw conveyor 2 is provided at the top of the humidity control tank 10 to dry the grains fried by the elevator. is configured such that it can be supplied into the humidity control tank 10 via the supply gutter 1, wherein the supply gutter 1
A plurality of drop ports 4 and 5 are provided in the transfer direction, and the drop port 4 on the side closer to the supply port 3 has a small amount drop port 9 on the bottom surface 6 and a large amount drop port 8 above the small amount drop port 9. Since it is a grain feeding device in a grain drying device, for example, when applied to the upper feeding gutter 1 of a circulation drying device, it is possible to
Even when a large amount of grain is fed at once, or even a small amount is fed by rotating the rotary valve 16, 16' as in circulation drying, it is possible to always drop the grain evenly,
In addition, it produces effects that can be implemented without requiring any expense.
