[Detailed Description of the Invention] [Industrial field of application] The present invention supports an arc-shaped receiving net arranged along the lower side of the handling cylinder by a guide provided in the handling chamber, and The present invention relates to a threshing device that can be inserted and removed from the upper part of a guide.

[Conventional technology]

In the threshing device configured so that the receiving net can be pulled out along the guide as described above, as disclosed in, for example, Japanese Utility Model Laid-Open No. 62-53650, handling as a movable member covering the upper part of the handling chamber is performed. In some cases, the chamber cover is vertically opened and closed, and a tool rest having a straw cutting blade is provided separately from the handling chamber cover.

[Problems to be solved by the device]

When taking out the receiving network with the disclosed structure,
Since the tool net is to be removed after the tool post is removed after the handling room cover is provided, there is room for improvement in terms of workability of inserting and removing the catch net.

Here, the present invention has been made by paying attention to the above-mentioned situation, and an object thereof is to improve workability at the time of receiving and inserting the net.

[Means for Solving the Problems]

A feature of the present invention is that, in the threshing device as described above, a movable member that covers the upper part of the handling chamber is supported so as to be vertically swingable and openable and closable about a horizontal axis parallel to the rotary axis of the handling barrel. A mounting base supporting the straw cutting edge is laterally mounted on the member, and a wall portion having a width larger than the lateral width of the receiving net extends from the mounting base to the vicinity of the upper end of the receiving net. A pin is provided on one side, and a notch is provided on the other side, and the pin is engaged with the notch by closing the movable member to restrict the position of the wall portion in the radial direction of the handling cylinder. The actions and effects are as follows.

[Action]

With the above configuration, when the movable member that covers the upper part of the handling chamber is opened, the mounting base with the straw cutting blade and the wall part escape upward together with the movable member, and the vicinity of the upper end of the net is greatly opened. As a result, the receiving net is easily pulled out upward.

When the movable member is in the closed state, the space between the mount and the upper end of the net is blocked by the wall portion, and the processed material is scattered from between the mount and the upper end of the net during threshing work. In addition to the above, the engagement structure of the pin and the notch can suppress the rattling of the wall portion in the radial direction of the handle cylinder.

[Effect of device]

As described above, by simply opening the movable member covering the upper part of the handling chamber, the upper end of the receiving net can be largely opened and the receiving net can be easily pulled out upward without the trouble of removing the tool rest.

The wall portion that closes between the upper end of the net and the mounting base may rattle in the radial direction of the handling cylinder during the threshing work, but this can also be prevented by a simple engaging structure.
