In the selection of soybeans, there is a method for removing non-standardized soybeans by selecting the soybeans according to their particle size by using a perforated sorting rotary cylinder that sieves non-standardized soybeans from a porous surface. However, since soybeans have a shape close to a sphere and are easy to roll, simply throwing selected soybeans into the multi-hole sorting rotary cylinder and rotating it will cause the selected soybeans to approach the lower part of the multi-hole sorting rotary cylinder. It is known that the sorting efficiency is much lower than that of cereals such as brown rice and white rice, and improvement of the sorting efficiency has conventionally been a technical issue in soybean sorting using a porous sorting rotating cylinder.

FIG. 8 is a partial cross-sectional view showing a mode in which the soybeans are put into one end of the rotary cylinder. FIG.

1 is a soybean sorting apparatus according to the present invention. This soybean sorting apparatus 1 sorts and removes non-standard soybeans from harvested and dried soybeans. In the soybean sorting apparatus 1, reference numeral 2 denotes a perforated sorting rotary cylinder. The perforated sorting rotary cylinder 2
It has a porous shape formed with a large number of circular holes 3 of a mesh for sieving non-standard soybeans mixed in the sorted soybeans (see FIG. 4), and has a cylindrical shape. The perforated sorting rotary cylinder 2 may be polygonal cylindrical.

As shown in FIGS. 1 and 2, the soybean sorting apparatus 1 has the above-mentioned perforated sorting rotary cylinder 2 provided horizontally in an exterior body 4 and rotatably supported by rotary shafts 5 and 5. Reference numeral 6 denotes a drive motor of the rotary rotary cylinder 2 for sorting. At one end side of the perforated sorting rotary cylinder 2 provided in the horizontal direction as described above, an input hopper 7 for charging the selected soybeans is provided.
On the other end side, there is provided a sizing discharge gutter 8 for transmitting the sorted sized soybeans. Horizontally installed rotary sorting cylinder 2
Is inclined so as to descend at a gentle angle from one end side to the other end side. Reference numerals 9 and 10 denote non-standard soybean discharge gutters.
It is provided so as to be roughly divided into two in the axial direction of the rotary rotary cylinder 2. The discharge gutters 9 and 10 may be one, three or more divided over the entire length of the perforated rotary cylinder 2, and may be unequally divided with an appropriate width in addition to substantially equal division as shown in the figure. The perforated rotary cylinder 2 is constructed by connecting and integrating two or more parts in the middle depending on the length in the axial direction. Numeral 11 denotes the connecting portion (see FIGS. 4 and 5).

One end of the perforated sorting rotary cylinder 2 is formed so as to be inclined in the direction of one end to form a loading section 12 for soybeans to be sorted.
An input hopper 7 for inputting sorted soybeans into the loading section 12.
The inlet 13 for the soybean to be sorted is formed downward with respect to the carry-in portion 12 of the multi-aperture rotating cylinder 2. For this reason, the sorted soybeans thrown into the throwing hopper 7 are thrown in along the lower surface of the perforated sorting rotary cylinder 2 via the loading section 12 (FIG. 7).
reference).

The soybeans to be sorted are transported in a thin layer along the perforated surface thereof along with the rotation of the perforated sorting rotary cylinder 2 in the perforated sorting rotary cylinder 2. The selected fallen soybean dropping and falling guides 14, 14 for dropping the sorted sorted soybeans toward the lower surface of the perforated sorting rotary cylinder 2,
It is provided for each half rotation angle of the perforated rotary cylinder 2 (FIG. 3,
6 and 8). The lifting and lowering guides 14, 14
The soybean has a rod shape having a convex soybean discharging surface 15 and extends over substantially the entire length of the perforated rotary cylinder 2. The above-mentioned lifting guides 14 and 14 thin the selected soybeans along the perforated surface of the perforated sorting rotary cylinder 2 within the range of 1/4 to 2/4 rotation angle with the rotation of the perforated sorting rotary cylinder 2. The soybeans are transported in a layered manner, and then the sorted soybeans which have been transported are dropped toward the lower surface in the porous sorting rotary cylinder 2 (see FIG. 8). Therefore, an interval is provided between the lifting guides 14 and 14 and the perforated surface of the perforated sorting rotary cylinder 2 such that one soybean of substantially regular size can pass through. In the illustrated embodiment, two perforations are provided between the support arms 16 and 16 at both ends of the perforated sorting rotary cylinder 2 and fixedly provided for each half rotation. However, the present invention is not limited to this configuration.

In the soybean sorting apparatus 1 configured as described above, the sorted soybeans fed from the loading hopper 7 are as shown in FIG.
As shown in (1), it is fed along the lower surface of the perforated rotary cylinder 2 through the carry-in section 12. And the multi-hole sorting rotary cylinder 2
With the rotation of the soybeans, the sorted soybeans are
The soybean is transported in a thin layer along the perforated surface of the perforated rotary cylinder 2 while being pushed up to the soybean discharging surface 15. Therefore, the sorted soybeans put into the perforated sorting rotary cylinder 2 are spread out in a thin layer along the perforated surface without leaning against the lower surface of the perforated sorting rotary cylinder 2, and the soybeans for the selected soybeans are removed. The sorting area is greatly expanded, and the sorting efficiency is greatly improved. In addition, the sorted soybeans which have been pumped in a thin layer as described above in the porous sorting rotary cylinder 2 fall from the upper limit position of the transport toward the lower surface of the porous sorting rotary cylinder 2 and are stirred by the drop impact. As a result, the sorting efficiency of the selected soybeans is further improved.

On the other hand, in the case where the cereal to be sorted is simply introduced into the perforated sorting rotary cylinder 2 to sort the soybean, the soybean is substantially spherical and easily rolls.
Of the selected soybeans does not form a thin layer along the porous surface due to the rotation of the porous sorting rotating body 2 and the sorting efficiency compared to the sorting of grains such as brown rice and white rice. Is extremely low.

In the soybean sorting apparatus 1 according to the present invention, the sorted soybeans introduced from one end side of the porous sorting rotary cylinder 2 are:
In response to the above-described sorting action, the standardized soybeans which are sequentially moved toward the other end and the non-standardized soybeans have been sieved out are sent out from the sizing delivery pipe 8. Then, the non-standard soybeans sieved from the perforated sorting rotary cylinder 2 are discharged from discharge gutters 9 and 10 below the perimeter of the perforated sorting rotary cylinder 2. From the input side of the sorted soybeans to the direction of delivery of the sized soybeans, the smaller the soybeans, the faster the sieves are sieved out. Small soybeans are discharged from the discharge gutter 10 into larger soybeans. Therefore, non-standard soybeans can be appropriately dealt with according to the usage mode. If the discharge gutter is divided into three or more, non-standard soybeans can be further subdivided for more appropriate use.

[0018]

According to the present invention, since the soybean has a shape close to a sphere and rolls easily, the phenomenon that the selected soybean leans on the lower part in the perforated sorting rotary cylinder is eliminated. Sorting efficiency can be greatly improved,
As a result, the effect of increasing the sorting processing ratio of the perforated sorting rotary cylinder and realizing the miniaturization of the entire apparatus can be obtained.
