2. Description of the Related Art Conventionally, in this type of thresher, a technique has been proposed which facilitates cleaning and maintenance of the handling chamber by swinging the handling barrel upward together with the handling barrel cover. It is known from Japanese Utility Model Publication No. 59-150231. Further, there is also known a technique in which the discharged straw conveying chain swings and opens up and down integrally with the handling cylinder cover.

[0003]

In such a known technique, only the handling cylinder is swung open and closed, so that the receiving net must be separately attached and detached. Therefore, not only the maintenance of the sorting room below the handling room but also the maintenance of the processing room is not easy in the double barrel type thresher, and there is a problem that the work efficiency is lowered. In addition, the driving device for the exhaust straw conveying chain is complicated and the cost is increased.

The present invention embodies a double-body type threshing machine that is easy to maintain. Therefore, the following technical measures were taken.

[0005]

[Means for Solving the Problems] That is, the technical means according to the present invention is a threshing with a receiving net 7 while axially transferring a supplied grain cullet with a handling barrel 2 internally mounted. A processing chamber 3 for processing, a processing chamber 14 that is installed in parallel on one side of the processing chamber, and internally accommodates a processing cylinder 15 that receives and transfers a processing object while axially processing it. A feed chain 8 provided along the side handle, and a handle cover 1 at the upper portion of the handle chamber, which is opposed to the feed chain 8 above the feed chain.
2 is composed of a holding rail 9 and a waste straw transport chain 32 for transporting the waste straw after threshing, and the handling chamber 3 is constructed so that it can swing and open outward together with the handling barrel. ,
The handling cylinder cover 12 is configured such that the processing cylinder 15 and the discharge straw conveying chain 32 can be integrally swingably opened and closed vertically.

[0006]

When the inside of the handling chamber is cleaned, the handling barrel cover is swung upward and opened, and the holding lever attached to this is opened.
Since the lever moves upward together with the handling cylinder cover and is separated from the feed chain, the feed chain can be opened to the outside. Therefore, when this feed chain is swingingly opened to the outside, one side surface of the handling chamber is largely opened. Since you can easily pull out the receiving net from this open part,
It can be taken out from the open part and easily cleaned.

When cleaning the sorting chamber and the processing chamber, the feeding chamber can be opened to the outside, and then the handling chamber can be rocked laterally outward. That is, the handling chamber can be swingably opened and closed around the longitudinal axis on the front end side by integrating the handling barrel and the receiving net in the handling chamber. Therefore, when the handling chamber is opened by swinging, the upper part of the sorting part is largely opened and the side of the processing chamber is opened, so that the maintenance of the processing part as well as the maintenance of the sorting part is facilitated. Become.

Since the processing cylinder and the discharge straw conveying chain move upward simultaneously with the opening of the handling cylinder cover, maintenance such as cleaning of the processing chamber and the discharge straw conveying section becomes easier.

[0009]

In summary, according to the present invention, since the handling cylinder and the handling chamber are opened to the side and the handling drum cover and the processing drum are integrally opened upward, the processing nets in and out of the processing chamber are taken in and out. Maintenance such as cleaning and cleaning becomes easy. By swinging and opening the handling cylinder cover, the processing cylinder, and the exhaust straw conveying chain integrally, the driving force to the exhaust straw conveying chain can be transmitted from the processing cylinder shaft, which results in a low cost.
