Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a combine in which a mowing unit for multiple-row mowing is provided in the front of the machine body so as to be vertically movable.

"Prior Art" Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 56-18030, there is a technology in which a chain case is attached to the upper part of the raising case and the driving force is input by a chain.

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, since the chain case is extended in a key shape between the rear surface and the upper end surface of the raising case, the upper side of the chain case becomes heavier than the lower side, and the chain case is detached. Sometimes it becomes unstable and it is not easy to simplify the shape of the chain case, and it is necessary to secure the strength necessary for mounting the chain case at the upper end of the pulling case, which simplifies the structure of the pulling case top side. There is a problem in that it cannot be performed easily.

Further, as disclosed in Japanese Utility Model Laid-Open No. 63-86727, there was also a technique of connecting an output case to a pulling pipe and raising the horizontal axis to transmit an input, but the horizontal axis is raised by a substantially vertical input shaft. Since it was connected to the tine chain, the input shaft and the raising case have different mounting angles,
Therefore, there is a problem that the distance between the upper surface of the pull-up case and the horizontal axis cannot be easily reduced, and there is a problem that the horizontal axis mounting position cannot be lowered as in the prior art.

[Means for Solving the Problems] Therefore, the present invention provides an input chain in which a tine chain having a raising tine is installed inside a raising case, the chain case is fixed to the rear surface of the upper end of the raising case, and the chain is installed inside the chain case. In a combine in which the output case is fixed to the upper end of the chain case and the horizontal axis installed in the output case is connected to the input chain, the upper opening of the raising case is closed by the chain case and the upper cover. , The output case is arranged inside the upper cover, and the left and right raising pipes for fixing one end side to the mowing unit body are connected to the left and right ends of the output case, and the both ends are supported by the left and right raising pipes. It is characterized by hanging multiple chain cases.

[Operation] Therefore, since the opening of the pulling case upper end side is closed by the chain case and the upper cover and the output case is internally provided in the upper cover, the structure of the pulling case upper end side can be easily simplified. Both the vertical width and front-back width can be easily reduced, and both ends of the output case are fixed by the left and right pull-up pipes. Therefore, the strength of the output case that supports the chain case and the upper end side of the pull-up case can be easily obtained, and the adjacent cases Since it is not necessary for the chain case to have the strength required for the connection between the upper ends of the pull-up cases, the chain case structure that is suspended from the output case can be simplified and downsized easily.
