The engine room (16) is a grain carrying auger for taking out grains in the grain tank (7).

The mowing section (9) is connected to the grain header (17) for receiving the uncut grain culm and the rear center of the header (17) to the threshing section (4). The grain header (17) includes a feeder house (18) for feeding, a reel (19) for scraping uncut grain, a reciprocating drive type cutting blade (20) and a platform auger (21), The cut culm to be taken into the header (17) is supplied to the threshing unit (4) by the supply chain conveyor (22) provided in the feeder house (18) for threshing treatment.

Further, as shown in FIGS. 1, 4, 5, 6, and 7, a dustproof hood (25) is formed by an upper surface hood (23) and a side hood (24) which are continuously arranged in an L shape. Then, the dust-proof hood (25) is internally provided with a suction-and-exhaust fan (26), the dust-proof hood (25) is attached to the upper surface and the left side surface of the feeder house (18), and after the grain head (17). A dust collection guide plate (27) is fixed on the side upper surface in the left-right width direction, and the rear side of the upper surface of the platform auger (21) is covered with the guide plate (27). The dust collection is performed on the upper surface of the feeder house (18). A fan (26) is provided to remove dust generated in the grain header (17) at a position distant from the operator in the driver's seat (12), that is, on the left side of the feeder house (18) opposite to the operator side, to generate dust generated in the grain header (17). 26) to suck and discharge Is configured as follows.

Further, a dust suction port (28) is opened on the upper surface of the feeder house (18), a dustproof net (29) is stretched and fixed to the dust suction port (28), and the fan (26) and the electric motor (30). ) Is fixed inside the upper hood (23) through the air guide plate (31), and the fan (26) is arranged to face the dust inlet (28), and the hinge (32) is provided on the upper surface of the feeder house (18). The front side of the top hood (23) is connected to the top side of the top hood (23) by fixing the back side of the top hood (23) to the top side of the feeder house (18) with bolts (33), and the hinge (32) is used as a fulcrum to move the top side hood (23) forward. The upper hood (23) is provided with a seal member (34) that can be freely opened and installed to close the gap between the feeder house (18) and the upper hood (23).

As shown in FIG. 5, the rear side of the side hood (24) is connected to the left side surface of the feeder house (18) through the hinge (35), and the side surface is fixed by the bracket (36) and the bolt (37). The front side of the hood (24) is fixed to the left side of the feeder house (18), and the side hood (24) is releasably attached to the hinge (35) as a fulcrum, and as shown in FIG. The side hood (24) is provided with a sealing material (38) that closes the gap between the joints between the hoods (24).

Then, at the time of harvesting rice or soybeans, the grain culms cut by the cutting blade (20) are sent to the front side of the feeder house (18) by the platform auger (21), and the bottom of the feeder house (18) is fed. Grain culm is supplied to the threshing part (4) by the chain conveyor (22) via the chain conveyer, and during the harvesting work, particularly large amount of dust is generated in the grain culm transfer part between the platform auger (21) and the feeder house (18). Although generated, dust in the grain header (17) and the feeder house (18) is collected by the suction / exhaust fan (26), and the upper and outer side hoods (23) (24) from the upper surface of the feeder house (18) to the outer side. ), Dust is discharged to the lower left of the feeder house (18), and dust generated in the grain header (17) is scattered toward the operator of the driver's seat (12). In addition to preventing this, the amount of dust carried into the threshing section (4) from the feeder house (18) is reduced.

Further, as shown in FIG. 8, a reaping switch (40) which is turned on in association with the operation of the reaping clutch lever (39) of the operation operating unit (13) to engage the reaping clutch, and the operation operating unit (13). A manual switch (41) to be installed and a stop switch (42) that is turned off by the rise of the feeder house (18) and detects the discontinuation of reaping due to the rise of the reaper (9) as shown in FIG. 4 are provided. , A stop switch (42) is connected in series to the harvesting and manual switches (40) (41) to be connected in parallel, and the electric motor (30) is powered through the switches (40) (41) (42). When the battery (43) is connected and either the reaping or the manual switch (40) (41) is turned on and the reaper (9) is lowered to keep the stop switch (42) on, When the suction / exhaust fan (26) is driven by the motor (30) and the cutting switch (42) is turned off by raising the cutting unit (9) such as a direction change at the headland, the cutting clutch lever ( 39) disengages the reaping clutch to stop the reaper (9), and when the switches (40) (41) are turned off, the motor (30) is turned off to stop the dust suction fan (26). The long culm attached to the bottom surface of the dustproof net (29) is dropped by its own weight to prevent clogging of the net (29).

Further, FIG. 9 shows a modified example, in which the suction / exhaust dust fan (26) can be easily formed by a sirocco fan, and the side hood (24) is used instead of the top hood (23). It is also easy to install the suction and exhaust fan (26) inside.
