ある。(G) Effect of the Invention As is apparent from the above description, the present invention is a threshing machine equipped with an under-type feed chain in which the side wall of the threshing room can be opened outward, and the lower edge of the feeding port of the threshing room is used. The inlet plate extending from the first plate is divided, and one plate on the feed chain side is integrally connected to the handling chamber side plate, and the other plate is attached to the machine side to divide the plate. Since it is configured to be detachable from the joint, it can be divided by opening the side wall of the handling chamber together with the feed chain to the outside.One inlet plate is integrally connected to the side plate of the handling chamber, so it is dissociated from the other plate. When the open side wall of the handling chamber is closed, one inlet plate is joined to the other side plate to be integrated into a working state. Also between the inlet plate and the side wall of the handling room and the feed There is no gap between the chain and the grain that has been shattered as in the past or dust generated by the threshing action does not fall from this gap, resulting in both grain loss and hygiene due to dust. It came to be able to solve the problem of.
