Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention provides a left and right concave frame with a blade holder in which a large number of blades are erected at predetermined intervals in the horizontal axis direction of the handling cylinder, The present invention relates to a concave of an all-culm throwing type threshing device in which a concave crosspiece unit including a vertical crosspiece and a horizontal crosspiece are alternately installed in the front and rear in the direction of removal and rotation.

[Conventional technology]

Conventionally, in the case of the concave, for example, the actual exploitation Sho 61-922.
As shown in Japanese Patent Publication No. 55, the receiving blade base and the concave cross rail unit are alternately installed between the left and right concave frames in the front-rear direction, and are formed between the blade base and the concave cross rail unit and in the concave cross rail unit. It is configured to filter the threshing-treated product treated by the rotary handling cylinder from the filtering slit.

[Problems to be solved by the invention]

However, in the case of the above structure, when a large amount of mud adheres to the root of the grain culm, the mud that has entered the handling room together with the cut grain culm adheres to the concave, and straw debris is attached to this. It may adhere and accumulate to block the slit for filtration, and the threshed product may not be filtered well.

Therefore, in order to take out the mud or the like clogged between the slits of the concave crosspiece unit, conventionally, a hand or a scraping stick or the like is inserted into the machine through a cleaning inlet provided on the side of the handling chamber and taken out. A large number of blade holders and concave beam units were installed in the handling room, and these were an obstacle to making it difficult to take out. .

The present invention has been made by paying attention to the above situation,
An object of the present invention is to provide a concave of an all-culm throwing type threshing device that can easily and easily take out mud, waste straw, etc. clogged in the slit of the concave crosspiece unit without polluting the handling chamber.

[Means for solving problems]

That is, the characteristic configuration of the concave of the all-culm throwing type threshing device according to the present invention is that a part of the plurality of concave cave units provided in the concave frame is configured to be detachable from the concave frame, One end side of the free concave claw unit is configured to be engageable and disengageable with respect to the engaging portion provided on the concave frame located on the side opposite to the opening formed in one side wall of the threshing device, and the other end side Is configured so that it can be fixedly connected to a fixing portion provided on the concave frame on the opening side, and its action and effect are as follows.

[Action]

When the slits of the concave crosspiece unit are clogged with discharge straw or mud, the concave crosspiece unit may be removed from the machine through the opening formed in the side wall to remove the mud and the like from the concave crosspiece unit. In addition, when installing the concave crosspiece unit in the handling room, insert the concave crosspiece unit into the handling room from the opening to engage and connect one end of the concave crosspiece unit to the engaging portion provided on the concave frame. The other end of the beam unit is fixed to a fixed portion provided on the concave frame on the opening side.

〔The invention's effect〕

As a result, it is no longer necessary to insert a hand or a scraping rod into the handling room one by one to remove the waste straws and mud clogging the slits of the concave beam unit, which makes it possible to easily clean the concave beam unit. Since the mud clogged in the concave beam unit can be removed outside the machine,
The handling room is never soiled with mud. Further, in the concave in which the concave beam unit is removed, there is a space, so that it is easy to insert a hand, a scraping tool, or the like into the handling room from this space, and it is possible to easily clean the handling room. .

Also, rather than removing the entire concave from the handling room, a portion of the concave cave unit is removed from the concave frame, so the detaching operation can be performed with a light force compared to when removing the entire concave from the handling room. At the same time, the workability is excellent in combination with the simple attachment / detachment connection structure as compared with the case where the entire concave part is detachably connected to the handling chamber.
