There is a technology disclosed in Japanese Laid-Open Patent Publication No. 622 or Japanese Laid-Open Patent Publication No. 61-78319.

[0003]

However, in the former one of the above-mentioned prior arts, the sorting air generated by a single compressed air fan is diverted so that the sorting surface of the rocking sorting body is directed rearward. Since it was designed to blow off, not only was the air volume insufficient and the separation and discharge of dust was inferior, but there was a limit to promoting the feed rate of grain removal on the rocking sorting surface, and it was not possible to improve sorting efficiency. . In the latter type, a plurality of compressed air fans generate the sorting wind. The sorting wind blows above the sorting surface of the swinging sorting body, which promotes the feed speed of grain removal by swinging. The present invention has a problem in that the front and rear length of the machine body becomes long due to the compressed air fan. Therefore, the present invention is the front and rear length of the selection unit for selecting grain removal from the handling room. While reducing the size of the machine and making the machine compact, the sorting air that is blown out from a separately provided compressed air fan is used effectively to increase the separation and discharge of dust and the feeding speed of grain removal on the rocking sorting surface. It was created for the purpose of improving efficiency.

[0004]

In order to achieve the above object, the present invention mounts a swinging selection body swinging in the axial direction of the handling cylinder from below the handling chamber toward the rear. The grain-removing grain is sorted, and the feed pan constituting the starting end of the rocking sorting body is divided into front and rear to form a first feed pan and a second feed pan having different steps, and is formed by the step difference. The discharge port of the second compressed air fan is looked into the space to blow it backward on the sorting surface of the swinging sorting body, and the lower lip plate of the fan case of the second compressed air fan is placed on the second fin. It is characterized in that it is made to enter the lower side of the starting end of the dopan.

[0005]

As a result, the grain removed from the handling chamber falls on the rocking sorter and is sorted by the combined use of the swinging action of the swinging sorter and the wind selecting action by the sorting wind. Is divided into front and rear to make a step difference, and the discharge port of the second compressed air fan is looked into the space formed by the step difference, and swing selection is performed by the selection wind that blows backward on the selection surface of the swing selection body. Dust in the grain removal falling on the body is separated and blown back, and the grain removal falling on the swing sorting body is sieved and sorted while being fed backward by the swinging action. At this time, the sorting air blown out from the second compressed air fan acts on the grain removing grains sent rearward by this swinging action to increase the feed speed, and the grain removing grains are efficiently sorted.

In this case, the lower lip plate of the second compressed air fan is inserted into the lower side of the starting end portion of the second feed pan, so that the grain-removed grains on the feed pan do not fall out of the sorting function.
