A frame, (3) is a machine frame installed on the track frame (1), and (4) is a feed chain (5) stretched to the left side, and has a built-in handling cylinder (6) and a processing cylinder (7). A threshing unit, (8) is a cutting unit provided in front of a threshing unit (4) and equipped with a cutting blade and a grain culm transport mechanism, and (9) is disposed at a rear part of the threshing unit (4) and a straw chain ( 10) (11) a straw processing unit facing the end, (12) a driver's cab arranged on the left side of the reaper (8) and having a driver's seat (13) and a driving operation unit (14), (15) Is an engine unit disposed at the rear of the cab (12), and (16) is an engine unit (1) on the right side of the threshing unit (4).
5) A grain tank disposed at the rear to store the grains from the threshing unit (4) via a fryer (17), and (18) a vertical discharge auger (19) for standing upright behind the tank (16). A) a vertically movable and swivelable lateral discharge auger for connecting the rear end to the upper end and discharging the grains in the tank (16) out of the machine;
Is an auger holder fixed to the upper surface of the right front corner of the threshing unit (4) and supporting the intermediate portion when the lateral discharge auger (18) is stored, which is configured to continuously cut and thresh. .

In the figure, reference numeral (21) denotes a transparent or translucent resin dust cover which covers the upper part of the mowing part (8), and the dust generated in the mowing part (8) is deposited on the driver's seat (13). Is prevented from reaching the operators.

[0007] A pair of left and right cover mounting brackets (23) are integrally attached to the front end of the openable / closable handle chamber upper surface cover (22) of the threshing unit (4) to form a handle (24). The bracket (23) is projected forward from upper left and right ends of the front cover (25), and a dustproof cover (21) is attached between the brackets (23). The bracket (23) has a linear lateral guide groove. (26) While forming a U-shaped vertical guide groove (27), a front guide pin (28) and a rear guide pin (2) are formed on the left and right side surfaces of the dustproof cover (21) facing the bracket (23).
9), the front guide pin (28) is slidably fitted in the horizontal guide groove (26), and the rear guide pin (29) is slidably fitted in the vertical guide groove (27). ) Can be moved between a use position indicated by a solid line in FIG. 1 and a storage position indicated by a virtual line in FIG.

The dustproof cover (21) in the use position
Is positioned substantially horizontally along the upper cover (22) by the front guide pin (28) located at the front end of the lateral guide groove (25) and the rear guide pin (29) located at the lower end of the vertical guide groove (27). , And protrudes forward from the upper end of the handling room front cover (25) to cover the upper part of the mowing part (8) in front of the handling opening (25) of the threshing unit (4), while the dustproof cover (21) is in the storage position. The front cover pin (28) located at the rear end of the horizontal guide groove (25) and the rear guide pin (29) located at the hook (30) at the upper end of the vertical guide groove (27). And the dustproof cover (21) is configured so as not to hinder the work during maintenance of the cutting unit (8).

In the storage position, the dustproof cover (21) is supported in a substantially upright posture from the upper edge of the handle (24) to the front side of the handling room front cover (25). The tip of the handle to the upper edge of the handle (24),
The round part (21a) on the upper surface of the dustproof cover (21) is also used as a supply guide for grain culm to be supplied to the handling port (24), and the dustproof cover (21) extends upward from the handling room upper surface cover (22). The output amount is held lower than the height of the holder (20), that is, the minimum turning height of the lateral discharge auger (18), and the dustproof cover (21) interferes with the auger (18) when the lateral discharge auger (18) turns, and is damaged. And prevents the dustproof cover (21) from obstructing the auger (18) in / out operation. Further, as shown in FIG. 4, when the handling room upper surface cover (22) is opened, the dustproof cover (21) is opened. 21) is positioned at least within the lateral width of the threshing unit (4) to prevent the dust cover (21) from interfering with the auger (18) in the housed state and being damaged, and to the driver's seat (13) side. Extend the dust cover (21) It not, the dust cover at the time of maintenance of the reaper performed from the driver's seat (13) side (8) (2
1) is configured so as not to hinder the work.

By the way, handles (31) are provided on the upper surface of the dust-proof cover (21) in the front and rear, and the dust-proof cover (21) supported at the use position is held by the handle (31) while pulling up the rear part to raise the front. By moving the part backward,
The dustproof cover (21) is moved to the storage position by the guide grooves (26) and (27) and the guide pins (28) and (29), and conversely is supported by the storage position.
By holding the handle (31) and lowering the upper part while moving the lower part forward, the dust-proof cover (21) is attached to the guide grooves (26) (27) and the guide pins (28) (29).
The dustproof cover (21) can be moved to each position with one touch by a single touch.

FIG. 5 shows a modification of the structure for supporting the dustproof cover (21).
5) is provided with a pair of left and right arms (32) for rotatably supporting one end, and the ends of the arms (32) rotatably support the substantially central portions on the left and right side surfaces of the dustproof cover (21). The dustproof cover (2) is provided on the arm (32).
A lock ball (33) that constantly presses against the side surface of 1) and a lock ball (33) provided on the side surface of the dustproof cover (21).
And two lock holes (34) for fitting the dustproof cover (21) in a substantially horizontal posture at the use position and a substantially upright posture at the storage position.

[0012]

As is apparent from the above embodiments, the present invention relates to a combine having a dustproof cover (21) for covering the upper part of the mowing part (8), wherein the dustproof cover (21) is provided in front of the threshing part (4). Make sure that the position of use
When using, the front end of the cover (21) is below and the rear end of the cover (21) is
It is located on top, and the top surface of the cover (21) when used is forward
From threshing section (4) in front of handle (24)
Since the dustproof cover (21) is stored movably at the storage position supported at the upper part, the amount of overhang of the cover (21) from the upper surface of the threshing unit (4) can be reduced when the dustproof cover (21) is stored. 18), the cover (21) can be prevented from protruding to the driver's seat (13) side when the upper cover (22) of the handling room is opened, and the mowing part (8) from the driver's seat (13) side can be prevented. In addition to improving the maintainability of the dustproof cover, when the dustproof cover (21) is stored,
A supply of grain culm for supplying the cover (21) to the opening (24)
It has remarkable effects such as being usable as an id .
