It was difficult to understand the action status of the weeding tools. The object of the present invention is to improve the visibility of the front of the raising device over the entire width of the pre-mowing treatment section, while suppressing an increase in the size of the operating cabin and providing an advantage when an opening / closing window is provided. It is to modify so that it can be done while trying.

[0004]

[Means for Solving the Problems]

 The characteristic configuration of the present invention is that in the operating cabin structure of the harvesting harvester described above, the lower edge of the front transparent plate of the operating cabin is located near the front edge of the operating panel, and the front side of the fuselage is more forward than the lower edge. The front transparent plate is attached in a forward tilting posture in which the upper end of the front transparent plate is located directly above the upper end of the stem-culm raising device in the state where the pre-mowing treatment unit is in the lowered work position, and the front transparent plate is attached. A triangular transparent plate continuous to the front transparent plate is provided at the front end of the lateral side wall of the operation cabin on the side of the vertical transport device, and the vertical length of the front edge of the triangular transparent plate is set to the vertical length of the front transparent plate.

[Action]

 The front transparent plate allows the head to be projected forward from the operation panel, and the eye to be positioned at a position located in front of the operation panel so that the stems can be raised and the front of the device can be easily seen from above. This can be made possible by the forward leaning posture. In addition, it is also possible to make the above-mentioned line-of-sight to the stem culm raising device at the lateral side of the operating cabin of the pre-mowing treatment unit, that is, the stem culm raising device located in front of the vertical conveyance device. This can be made possible by the plate and its shape. If the front transparent plate is tilted forward and the triangular transparent plate on the side wall is used to enable the above-mentioned line-of-sight, compared to the case where the front transparent plate is mounted in a vertical posture at a position projecting forward from the operation panel, the operation panel can be installed. The cabin that projects further forward becomes smaller. If an opening / closing window is provided at a position behind the triangular transparent plate on the side wall of the vertical conveyor, the front edge of this opening / closing window should be located as close to the front as possible to maximize the open area. This is made possible by the arrangement of the vertical edge and the corner of the rear edge of the triangular transparent plate.
