Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a fine sorting section for sorting processed products leaked from a handling room by swinging and transporting the sorted products into grain and second grain, and the sorting wind from Kara-moh is subjected to the fine sorting. A guide plate that guides in a direction along the longitudinal direction of the section is continuously provided at the free end of the peripheral wall of the Karako, which is on the side where the sorting wind is entrained, and the sorting wind is directed to the vicinity of the sink plate of the first item recovery unit. The present invention relates to an oscillating sorting device in a threshing device, which is provided with a wind direction plate that can be distributed to the wind and the wind heading in the vicinity of the Glen sieve of the fine sorting unit.

[0002]

2. Description of the Related Art Conventionally, in the rocking sorting device in the above threshing device, the free end portion of the Karato is integrated with the peripheral wall of the Karato so as to have a fixed posture, as shown in, for example, Japanese Patent Application Laid-Open No. 5-192032. It was in a fixed position as it was, and there was no device or member on the air passage of the sorting wind from Karano, which could increase or decrease the amount of the sorting wind.

[0003]

In this type of threshing apparatus, for example, when the amount of treated air is large in the space under the grain sieve when the amount of the sorting air toward the vicinity of the grain sieve of the fine sorting unit is large when the amount of processed material is small. Since the grain in the reduced state is subject to strong winds at a high position, it is easily blown back, and for that reason, a large number of No. 3 scatters and a large number of No. 2 reduction grains are taken out to be removed. There is a problem that it is easy to lose. In addition, when there is a small amount of sorting wind heading for the vicinity of the Glensieve when there are many processed products, it is difficult to reliably blow away the scraps to the rear and there is a problem that most of the scraps are likely to be mixed into the item recovery part. .

Under such circumstances, according to the above-mentioned conventional structure, no device or member for adjusting the air volume of the sorting air is provided on the air passage of the sorting air from Kara no Tsumugi. The only way to solve the above problems when the amount of processed material is large or small is to increase or decrease the output of Kara-moh to increase or decrease the total amount of sorting wind.

However, with this means, it is possible to increase or decrease the amount of the sorting air toward the vicinity of the Glen Sieve of the fine sorting unit to the amount of the sorting wind toward the vicinity of the sink plate of the first object recovery unit. However, the method of increasing and decreasing the sorting wind was rough and rough, and it was not efficient.

The present invention has been made in view of the above points, and an object thereof is to increase or decrease the sorting air in accordance with the change in the amount of the processed material, and place emphasis on the place where the increase or decrease is required. An object of the present invention is to provide an oscillating sorting device in a threshing device that can be performed and can efficiently increase and decrease the sorting air.

[0007]

The feature of the present invention is that the free end portion of the peripheral wall of the Kara-mino on the side where the selection wind is entrained is configured so as to be movable in the radial direction with respect to the tip rotation locus of the Kara-mano fan. There is something.

[0008]

[Function] Since the free end portion of the peripheral wall of the Kara-mino on the side where the selection wind is entrained is configured to be freely movable in the radial direction with respect to the tip rotation locus of the Kara-mano fan, for example, when there are few processed products, If the free end is separated from the trajectory of the tip of the Karako fan in the radial direction, the volume of the sorting wind that gets caught in the Karoh will increase, and the volume of the sorting wind that goes to the vicinity of the Glen Sieve of the fine sorting unit will be small. Therefore, it is possible to prevent the grains from being scattered rearward due to the strong wind at the high position of the grains having a low density in the space below the grain sieve. In addition, when there are many processed materials, if the free end portion is brought closer to the tip rotation path of the Karako fan in the radial direction, the air volume of the selection wind that is caught in the Karako will be reduced, and the precise selection unit The amount of the sorting wind toward the vicinity of the Glen sieve increases, and the strong wind is received when the straw dust is at a high position, so that the straw dust can be reliably blown back. As described above, according to the above configuration, the free end portion of the peripheral wall of the Kara-mino on the side where the selection wind is entrained is closely spaced in the radial direction with respect to the tip rotation locus of the Kara-mano fan, thereby responding to a change in the amount of processed material. Then, it is possible to increase or decrease the sorting wind while focusing on the place where the increase or decrease is required.

[0009]

Therefore, in response to the change in the amount of processed material,
Since it is possible to increase / decrease the sorting air with emphasis on the place where it needs to be increased / decreasing, it was possible to provide the swing sorting device in the threshing device capable of efficiently increasing / decreasing the sorting air.
