Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing machine in which a handling chamber in which a handling barrel is mounted on an inner shaft is swingably opened and closed with respect to a lower sorting chamber.

2. Description of the Related Art Conventionally, in a threshing machine of this type, a technique for swinging and opening the handling barrel upward together with the handling barrel cover to facilitate cleaning and maintenance of the handling chamber has been described, for example, as follows. It is known from, for example, Japanese Utility Model Publication No. 59-150231.

[0002]

In such a known technique, only the handling cylinder is swung open / closed, so that the receiving net must be separately attached and detached. Therefore, since there is a feed chain in addition to the maintenance of the sorting room below the handling room, it is not easy to attach and detach the receiving net, and there is a problem that the work efficiency is reduced.

The present invention is intended to embody a threshing machine which facilitates maintenance of a handling room and a sorting room. Therefore, the following technical measures were taken.

[0004]

[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 in which a handling barrel 2 is internally mounted. The handling chamber 3 to be processed, a feed chain 8 provided along a handling opening on one side of the handling chamber 3, and a handling barrel cover 12 above the handling chamber, which is provided opposite to the handling chamber 3. And a holding rail 9 mounted on the handle barrel cover 9. The holding rail 9 can swing up and down together with the handle barrel cover 12 to open and close.
The dochien 8 is constructed so as to be swingable and opened outward when the holding rail is moved upward, and the handling chamber 3 is vertically divided with respect to the lower sorting chamber, and the feed chain is It is characterized in that when it is opened outward, it can swing and open toward the inside and outside.

[0005]

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 removed.
Since the lever moves upward together with the handle barrel 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 the receiving net can be easily pulled out from this open part,
It can be taken out from the open part and easily cleaned.

Further, when the inside of the sorting chamber is cleaned, 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 cylinder and the receiving net in the handling chamber. Therefore, when the handling chamber is rocked open,
Since the upper part of the sorting section is largely opened, maintenance of the sorting section becomes easy.

[0007]

As described above, according to the present invention, since the feed chain can be opened to the outside of the handling room, it is easy to attach and detach the receiving net as well as the maintenance inside the handling room. Since the handling barrel and the handling barrel receiving net are opened integrally, it is easy to maintain the sorting section below the handling chamber. In particular, rocking sorting shelves can be maintained simply by opening the handling room, removing the complexity of removing the handling barrel nets, and improving the work efficiency of cleaning, inspection and maintenance.

Moreover, since the handling chamber is constructed such that the feed chain is first opened outside and then the swinging is opened, the swinging and opening / closing of the handling chamber itself is facilitated, and the construction itself can be performed easily without any trouble. be able to.
