Description

[Detailed Description of the Invention] [Industrial field of application] The present invention has an axial-flow-type handling cylinder that pivots forward and backward in a handling room, while rotating around an axis in the front-rear direction and sending a processed material to the rear. A receiving net is stretched along the lower side of the handling cylinder, a sorting unit is provided below the receiving net, and the second item sorted by the sorting unit is returned to the sorting unit. A certain all culm input type combine.

[Conventional technology]

In such an all-culm input type combine, a spiral strip is planted in the outer peripheral portion of the handling cylinder as disclosed in Japanese Patent Laid-Open No. 60-244223, while handling the cut culm thrown into the handling chamber while processing. It is known to gradually send it backward.

[Problems to be solved by the invention]

However, in the spiral strips that are connected as described above,
Since the harvested culm cannot be effectively hit, the handling process could not be performed sufficiently. Therefore, in order to remedy this drawback, it has been proposed that instead of a spiral strip, a handle tooth is planted in a spiral shape so that the grain culm is constantly hit and the grain culm can be conveyed backward while being treated.

However, even though this is effective in handling, the processed material that has leaked through the net tends to accumulate in the center of the left and right of the sorting unit, which is directly below the receiving net, and the original nature of the sorting unit. It is expected that a new problem will occur that the performance will not be fully exhibited, and it was still difficult to put it into practical use.

Therefore, the present invention has an object to make the distribution of the leaked substances accumulated on the selection portion of the handling cylinder having the handling teeth uniform, thereby opening the way to practical use of the handling cylinder.

[Means for solving problems]

The characteristic configuration of the present invention is that the handling teeth are helically planted on the outer periphery of the handling cylinder, and the second object is returned to the sorting section located below the lower side of the receiving net in the rotation direction of the handling cylinder. In that the tooth is provided in each of the portion located on the upper side in the rotating direction of the handling cylinder on the net and the portion located in the lower vicinity of the lowermost part of the handling cylinder,
The action and effect are as follows.

[Action]

In other words, the cut culm that has been thrown into the handling room is handled by the handling teeth and then sent to the rear. In that case, toothing is provided in the part on the upper side of the net in the direction of rotation of the handling cylinder and in the part located near the bottom of the bottom of the handling cylinder. As a result, the amount of leaked substances from the net increases, and on the sorting section, the amount of leaked substances accumulates on the upper side in the direction of rotation of the handling cylinder and near the bottom of the lowermost part of the handling cylinder. Further, the second material is halved and deposited on the sorting section located on the lower side of the receiving net in the rotating direction of the handling cylinder. Therefore, by changing the number and arrangement of the teeth to extend the leak amount and balance it with the returned second substance, the leak substance accumulated on the sorting part will be distributed more evenly. Become.

[Effect of device]

As a result, the original performance of the sorting section in the handling cylinder having the handling teeth can be fully exerted, and the handling cylinder can be put into practical use.
