The present invention relates to a threshing screening apparatus for threshing harvested rice stems in combines and the like, and for sorting the threshing products.

In general, this type of threshing sorting device is provided with a gutter receiving a number one at a lower part of the swinging sorting device, while a swinging sorting device is installed in the lower part of the feeding chamber in which the barrels are built-in. The gutter which the second person receives is discharged, and the wind blows from the lower part of the rocking | swing sorting apparatus which was mentioned earlier, and the straw crumbs in this sorting room etc. in the sorting room in the upper part of the rear end in the rocking | swing sorting apparatus which were mentioned above It is well known that the suction type exhaust fan which sucks and discharge | releases to the outside is discharged. (For example, Unexamined-Japanese-Patent No. 57-32681 etc.).

By the way, the suction type dust collecting fan in this type of threshing sorting apparatus is sucked with straw dust and the like with the sorting wind, so that the straw dust and the like fill up inside the dust collecting fan. It is necessary to check and clean.

By the way, in the conventional threshing sorting apparatus, since the above-mentioned back exhaust fan is attached to the side plate which forms one side of the sorting chamber, there existed a problem that the operation | work of inspection and cleaning with respect to this back exhaust fan was extremely difficult.

According to the present invention, in the recent threshing-screening apparatus, as described in Japanese Patent Application Laid-Open No. 1-167840, the feed chain is installed on the side plate forming one side of the processing chamber, and the side plate is configured to open and close quickly. The technical problem is to make it possible to solve the problem mentioned above by using it, and to make it easy to check and clean the rocking | crossing sorting mechanism.

In order to achieve this technical problem, the present invention provides a rocking sorting mechanism at the bottom of a feeding chamber equipped with a feed chain according to one side, and a gutter receiving a number 1, a gutter receiving a number 2 and a tuyere fan at the bottom of the rocking sorting mechanism, respectively. In the threshing-out apparatus which arrange | positioned the suction backing fan outside to the outside in the sorting chamber above the terminal part of the rocking | swinging sorting mechanism mentioned above, the side plate in one side of the feeding chamber which were mentioned The side plate on one side of the sorting chamber described above is constituted by an integrated side member, and the feed chain provided on the side member is mounted, while the side plate near the end of the sorting chamber on which the side member is posted. It is configured to be rotatable by opening outward with respect to the part, and furthermore, the suction port in the exhaust fan is transferred to the suction type exhaust fan that is delivered to the side member that has been electric. It was configured to attach to being in a screening room.

In such a configuration, when the side member provided with the feed chain is rotated outwardly, the front side of the feeding chamber can be opened, but at the same time, the front side of the sorting chamber can also be opened.

In addition, by providing a suction backing fan for the screening chamber described above, the backing fan described above can be taken out of the screening chamber by an open rotation of the side member outward.

Therefore, according to the present invention, the inspection and cleaning of the feeding chamber can be made extremely easy, and the inspection and cleaning of the sorting chamber and the suction type exhaust fan of the sorting chamber can be carried out very easily. .
