It moves, and a set number of waste straw bundles fall together in a vertical posture.

That is, according to the configuration of claim 2, the same operation as the operation [a] or [b] by the configuration of claim 1 can be achieved. As described above, the release / conveyance mechanism is configured by providing a transport chain with a projection and a guide rail opposed to the transport chain with a protrusion. Since the structure of the above is slightly modified, the structure can be simplified.

[Effect] Therefore, according to the configuration of claim 1, the workability can be improved by the above operation [1].

According to the structure of claim 2, in addition to the effect similar to the effect of the structure of claim 1, the structure can be made compact by the above operation [b], and the production cost and maintenance can be reduced. It became advantageous in terms of.
