Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention divides a handling chamber forming wall into an open/close side wall portion and a fixed side wall portion at a dividing line that intersects with the grain culm supply port, and separates the open/close side wall portion. The handling barrel is attached to the fixed side wall portion so as to be swingable up and down about an axis that is located on the opposite side of the grain culm supply port from the handling port and extends in the longitudinal direction of the handling port, and the handling barrel is attached to the opening/closing side wall portion. This invention relates to a threshing device attached to a

[Conventional technology]

In the above-mentioned threshing device, conventionally, for example, Japanese Patent Application Laid-Open No. 59-17
As shown in Japanese Patent No. 9014, when the open/close side wall portion is in the closed state, the open/close side wall portion and the fixed side wall portion are in direct contact over the entire length of the parting line to form a seal between the two wall portions.

[Problem to be solved by the invention]

Conventionally, due to manufacturing errors and installation errors of wall parts and various parts such as fixtures, when the opening/closing side wall part is closed,
The opening/closing side wall portion and the fixed side wall portion come into contact at a portion corresponding to the part on the opposite side of the parting line from the grain culm supply port side, but do not contact at a part corresponding to the part on the grain culm supply port side of the parting line, leaving a gap. In some cases, the closing hook, which is designed to act on a part of the opening/closing side wall near the grain supply opening, would not engage properly, and the closing hook of the opening/closing side wall would become impossible or insufficient. .

An object of the present invention is to make it difficult for the opening/closing side wall portion to be closed improperly.

[Means to solve the problem]

The characteristic configuration of the present invention is that in the snow-raised threshing device, when the opening/closing side wall portion is in the closed state, the opening/closing side wall portion and the fixed side wall portion contact at a location corresponding to the grain culm supply port side portion of the parting line. In addition, the opening/closing side wall portion is formed and attached to form a gap at a portion corresponding to the part opposite to the grain culm supply port side of the dividing line, and an elastic sealing material is provided to close the gap.

The functions and effects thereof are as follows.

[For production]

In a normal assembled state, the opening/closing side wall part and the fixed side wall part will come into contact at the grain culm supply port side, and a gap will be formed at the counter-killing culm supply port side, so even if this occurs, it will be unnatural. Even if manufacturing or assembly errors occur, the gap will be slightly wider or narrower than normal, and both wall portions will be able to absorb the grain before the part on the side opposite to the grain culm supply port. A state where the contact occurs at the culm supply port side is obtained.

Even if the gap is formed, and even if the width of the gap changes slightly, the elastic sealing material will surely come into contact with both wall parts due to the change in compression deformation, and the seal between the wall parts will be ensured. You can do it like this.

〔Effect of the invention〕

Due to the above-mentioned gap, regardless of manufacturing errors or assembly errors, the opening/closing side wall part is securely closed in the normal state where it contacts the fixed side wall part at the grain culm supply port side, and the closing hook is securely closed. It has become an equivalent product that can be used to close and lock reliably.
