The cabin door 4 according to the embodiment has a configuration in which the inner component member 4a and the outer component member 4b of the door member are firmly connected from the inner side by the reinforcing member 29 to increase the rigidity and to be resistant to impact.
Although the cabin 3 configured as described above is omitted in the drawings, the roof member 12 is equipped with air conditioning equipment and is configured to perform indoor air conditioning.
[0011]
Next, the operation will be described.
First, for the combine work, the operator sits in the cockpit of the cabin 3 and starts the engine to prepare for the mowing and threshing work. At the same time, the operator operates the operation panel (not shown) to Set the temperature to the desired temperature. Then, the air conditioning apparatus starts the air conditioning operation based on the equipped control mechanism, and can keep the cabin 3 in a comfortable state.
[0012]
In such a state, when the operator advances the combine, the grain culm in the field is cut by the front cutting pre-treatment device 11, transported rearward and upward by the transport device, and supplied to the threshing machine 10. . Then, the cereal is harvested by the threshing machine 10 so that the cereal grains selected by the threshing treatment are harvested.
Now, during the above operation, when opening the window of the cabin 3, the window glass 16 of the rear window 15 'has the grip / locking tool 20 and is pushed outward to hold the grip / locking tool. 20 can be removed from the locking receiver 21 and rotated in the direction of the arrow shown in FIG. When the window glass 16 is strongly pressed against the front door frame 17, the locking tool 19 engages and is fixed to the front locking receiver 22, and the rear window 15 'is opened.
