  Conventionally, as one form of combine, there has been provided a driving part in the cabin. The driving part has a handle attached to the upper end of the handle column, and a seat is disposed at the rear of the handle, and the left side of the seat. A side operation panel is arranged at one position, and operation means such as a shift lever is provided on the side operation panel (see, for example, Patent Document 1).

  The side operation panel is arranged with the left side wall (outer side wall) in contact with the left side wall of the cabin, and the entrance door is attached to the right side wall of the cabin.

In addition, an inspection port is formed on the right side wall (inner wall) of the side operation panel, and the inspection port is opened and closed with an opening / closing lid so that the inside of the side operation panel can be inspected through the inspection port. Yes.
JP 10-75634 A

  However, in the above-described side operation panel, since the inspection port and the seat are arranged close to each other, the work of inspecting the side operation panel through the inspection port is very complicated.

  Therefore, in the present invention, in the combine in which the side operation column is disposed in the cabin, the side operation column is disposed with the opened left side surface in contact with the inner surface of the left side wall of the cabin and the left side wall of the cabin. The combine is characterized in that the inspection port is opened, and the inspection port is opened and closed through an opening / closing lid so that the inside of the side operation column can be inspected from the left outside through the inspection port. It is to provide.

  Further, according to the present invention, the side operation column includes a column main body, a support machine frame provided in the column main body, and operation means assembled to the support machine frame, and is detachable from the cabin floor. It is also characterized by being attached.

  (1) In the first aspect of the present invention, in the combine in which the side operation column is disposed in the cabin, the side operation column is disposed such that the opened left side surface is in contact with the inner surface of the left side wall of the cabin. The inspection port is opened on the left side wall of the cabin, and the inspection port is opened and closed through an opening / closing lid so that the inside of the side operation column can be inspected from the left outside through the inspection port. .

  In this way, the inside of the side operation column can be inspected from the outside through the inspection opening opened on the left side wall of the cabin, so that the seat does not become an obstacle and the inside of the side operation column can be inspected easily. Thus, the inspection work efficiency can be improved.

  (2) In the present invention according to claim 2, the side operation column includes a column main body, a support machine frame body provided in the column main body, and an operation means assembled to the support machine frame body. It is detachably attached to the floor.

  In this way, the side operation column including the column main body, the support machine frame provided in the column main body, and the operation means assembled to the support machine frame is detachably attached to the cabin floor. Therefore, the side operation column can be arranged on the floor of the cabin in a state where the operation means is assembled to the column main body via the support machine frame in advance, and the side operation column is complicated in the side operation column. When performing maintenance or the like, the side operation column can be removed from the floor of the cabin, and maintenance or the like can be easily performed outside the cabin. Therefore, the inspection work efficiency can be improved also from this point.

  The best mode for carrying out the present invention will be described below with reference to the drawings.
