Description

  The present invention relates to a combine in which a threshing device is mounted on a traveling machine body and a waste straw processing device for treating waste straw from the threshing device is provided behind the threshing device.

  A threshing device and a grain storage device are juxtaposed side by side, and the waste straw processing device is directed rearward through a longitudinal axis on the side surface of the threshing device opposite to the side where the grain storage device is present. It attached so that rocking | fluctuation opening and closing was possible, and it comprised so that the said waste straw processing apparatus could be freely opened to the non-processing attitude | position which spaces apart with respect to the said threshing apparatus (refer patent document 1).

JP-A-10-215658 (paragraph number [0016] and FIGS. 1 and 5)

In the above configuration, since the waste straw processing apparatus can only be opened rearward, it is clogged between the outer case of the waste straw processing apparatus and the waste straw shredding blade such as a chopper which is a specific means of the waste straw processing apparatus. Even if it is necessary to remove the waste straw etc., maintenance work is difficult because the clogged portion is located on the rear side which is difficult to reach from the open side of the waste straw treatment apparatus.
On the other hand, it is conceivable to adopt a configuration in which the waste wall treatment apparatus is provided with a waste wall treatment apparatus body provided with a chopper and a cover that covers the body, and the cover is simply opened rearward. Since the processing apparatus main body cannot be opened, there is a drawback that it is difficult to perform maintenance work on the chaff sheave in the threshing apparatus.
Since the installation position of the vertical axis that swings and opens the waste straw processing device is provided on the side surface opposite to the grain storage device existing side in the threshing device, when the waste straw processing device is opened backward Then, the waste straw processing apparatus protrudes to the lateral side of the traveling machine body. Therefore, if there is a wall in the vicinity of the waste wall treatment device, it cannot be fully opened, and the maintenance work posture will be cramped, and even if it can be fully opened, it will protrude greatly outside the aircraft, so other things There are drawbacks such as contact.

  An object of the present invention is to provide a combine drainer processing device mounting structure for a combine that can easily remove clogs and the like in the drainer processing device as well as the equipment in the threshing device and perform a recovery operation.

The cover is configured to be openable to a non-processing posture that is separated from the main body, and the cover is configured to be openable to a non-processing posture that is spaced apart from the main body of the waste straw processing apparatus. It is.

[Action]
Since the waste straw processing apparatus is composed of a main body part that shreds the waste straw and a cover that covers the main body, and the waste straw processing apparatus body can be swingably opened and closed together with the cover, Alternatively, maintenance work can be performed by taking it out of the threshing apparatus. It is possible to remove the cover while visually recognizing clogs or the like that are clogged between the cover and the waste straw treatment apparatus body by opening the cover to the waste straw treatment apparatus body.

〔The invention's effect〕
Therefore, maintenance work not only in the threshing apparatus but also in the waste straw processing apparatus can be easily performed.

〔Constitution〕
In invention of Claim 2 of this invention, while arrange | positioning a grain storage apparatus in the side position of the said threshing apparatus in the invention of said Claim 1, a waste straw processing apparatus main body is set to the said non-processing attitude | position. In order to switch, a swing fulcrum is provided behind the threshing device on the side where the grain storage device is present, and the waste wall treatment apparatus main body is configured to swing back and open around the swing fulcrum. At some point, the effects are as follows.

[Action]
Since the swing support point is set on the side where the grain storage device is located in order to switch the waste wall treatment device main body to the non-processing posture, it should be fully opened toward the rear even if the wall surface or other machines are adjacent to each other. Can do.

〔effect〕
Therefore, there is no restriction on the degree to which the waste wall treatment apparatus main body is opened, and maintenance is easy.

〔Constitution〕
According to a third aspect of the present invention, in the invention according to the first or second aspect, the cover is detachable from the main body of the waste straw treatment apparatus. Street.

[Function and effect]
Since the cover can be removed, the opened state and the removed state can be properly used according to the maintenance work, and the work can be performed more easily.

〔Constitution〕
According to a fourth aspect of the present invention, in the invention according to the third aspect, the cover is attached to the waste wall treatment apparatus main body so as to be swingable and openable, and the rocking opening and closing fulcrum is a fulcrum pin. The support boss that supports the fulcrum pin is configured, and the fulcrum pin and the support boss are configured to be freely inserted and removed. The operational effects are as follows.

[Function and effect]
