  The conventional rear window is composed of a simple flat window, and the rear end of the driving cabin cannot be opened wide and the driver opens the rear window to get out of the body and perform a rear view operation. It was difficult.

  The present invention has been made paying attention to such points, and has as its main purpose to make it possible to easily perform the backward visual recognition work by widely opening the rear end portion of the driving cabin.

The first invention is a combine with a cabin in which a threshing device and a grain recovery unit are mounted in parallel on the left and right in the traveling machine body, and a driving cabin is provided in front of the grain recovery unit.
Among the left and right rear struts provided at the rear part of the driving cabin, the rear struts inside the fuselage are provided to be located in front of the rear end of the driving cabin, and the lateral side and the rear surface inside the fuselage are provided at the rear part of the driving cabin. The provided rear opening / closing window is provided so as to protrude rearward from the rear support column inside the fuselage, and the rear opening / closing window is configured to be swingable open.

  According to the said structure, since there is no support | pillar in the corner | angular part inside the body in the rear end of a driving | running cabin, the wide visual field which extends back and threshing apparatus upper direction is securable. When the rear opening / closing window is swung up, a wide range including the corners on the rear side of the driving cabin including the corners on the inside of the aircraft body is opened, and it becomes easy for the driving operator to get out of the opened opening.

  Therefore, according to 1st invention, the rear-end part of a driving | running | working cabin is open | released widely, and a backward visual recognition operation | work can be performed easily.

According to a second invention, in the first invention,
The left and right rear struts are provided in front of the rear end of the driving cabin, and a rear window is provided between the left and right rear struts. The rear windows are located on the inner side of the rear opening / closing window and the fuselage. It is comprised by the rear part fixed window located in an outer side.

  According to the above configuration, although the lateral width of the rear end of the cabin that can be opened by the rear fixed window is narrow, the rear opening / closing window can be opened to the lateral side of the interior of the aircraft, so that the opening width at the rear portion of the cabin can be increased.

According to a third invention, in the second invention,
A pre-cleaner connected in communication with the combustion intake system of the engine is disposed close to the rear of the rear fixed window.

  According to the above configuration, even if the precleaner is provided behind the operation cabin, the rear opening / closing window can be opened without being disturbed by the precleaner, and the cabin rear portion can be opened wide and wide.

  FIG. 1 shows an entire side surface of a self-removable combine combine with a cabin, which is an example of a combine with a cabin according to the present invention, and FIG. The combine with a cabin includes a threshing device 3 and a grain collection unit 4 mounted in parallel on the left and right on a traveling machine body 2 having a pair of left and right crawler traveling devices 1, and a plurality of crops are raised and cut. A reaping part 6 for feeding to the feed chain 5 mounted on the left side of the threshing device 3 is connected to the left front part of the traveling machine body 2 so as to swing up and down, and a driving cabin 7 is connected to the right front part of the traveling machine body 2 with the grain. The structure is located in front of the grain collection unit 4.

  A box-shaped prime mover 9 in which a water-cooled engine (not shown) is accommodated and arranged horizontally is provided behind the drive cabin 7, and a driver seat 10 is provided on the prime mover 9. The right side surface of the prime mover 9 is exposed to the outside of the machine, and the outside air taken in from the main intake port 11A of the dust-proof structure formed on the outer face is introduced into the prime mover 9 to cool and drive the radiator 12. After being used for the internal ventilation of the part 9, it is discharged from the driving part 9 toward the inside of the body (the cutting part 6 is a hook).

  A box-shaped air guide duct 13 is provided on the rear upper surface of the prime mover 9, and outside air is also taken in from a dust-proof auxiliary air inlet 11 </ b> B formed on the outer surface of the air guide duct 13. The outside air taken in from 11A is merged and introduced into the prime mover 9.
