As shown by a two-dot chain line in FIG. 7, the other holding piece 42c is provided so as to abut against the side portion of the swinging piece 12el in the storage position and maintain the swinging piece 12el in the storage position.

[0048] According to the return bar 40 having the above-described configuration, the operator or the like manually opens the shutter curtain 10 halfway and raises the automatic return prevention mechanism 12e by hand to the storage position (FIG. 6). When the engaging portion 42 is engaged with the seat plate member 12 including the automatic return prevention mechanism 12e from below, the swing piece 12e 1 is maintained in the storage position by the other holding piece 42c. At the same time, the seat plate member 12 can be stably held between the two holding pieces 42b and 42c.

Thereafter, when an operator or the like moves the rod body 41 so as to lift it upward, as shown in FIG. 5, the entire seat plate member 12 is accommodated in the outlet member 37, and the locked member 12d is moved backward. The shutter curtain 10 can be kept fully open by engaging with the automatic closing device 36 described below.

[0049] Further, the left and right guide rails 20, 20 each have a cross-sectional shape surrounding an end portion of the flexible screen portion 11 in the width direction, and contact target portions p such as a floor surface, the ground, and a frame member, It is arranged between the paddle equipment 30.

As shown in FIG. 2, the guide rail 20 on one side (left side in the illustrated example) is fixed at a position relatively close to the opening 94 on the wall 93, and the guide rail 20 on the other side (right side in the illustrated example) 93 is fixed at a position away from the opening 94 so as to avoid the operation panel 3

Accordingly, the shutter curtain 10 is longer in the width direction than the opening 94, and the center of the shutter curtain 10 in the width direction does not coincide with the center c of the opening 94 in the width direction. Arranged in a state shifted to the 3 side.

Further, the left and right handle portions l lal and l lal are arranged such that the center in the width direction between them substantially coincides with the center c in the width direction of the opening 94.

[0051] Further, the scraping device 30 includes a scraping body 31 that winds and unwinds the shutter curtain 10, left and right shaft bodies 32a and 32b that support the scraping body 31 from the shaft core side, and the shafts. Main body 3 Left and right bearing brackets 33a and 33b that support 2a and 32b, and take-up body 31 in the winding direction An urging member 34 for urging, a speed reducing device 35 that suppresses rotation of one shaft body 32b in the extending direction, and an automatic closing device 36 that automatically extends the shutter curtain 10 in response to an emergency signal in the event of a fire, etc. The shutter curtain 10 is sent out from an outlet member 37 (see FIG. 5) that is provided and disposed in the lateral width direction on the lower side of the harvester 31.

[0052] According to the illustrated example, one shaft main body 32a is disposed on the left side of the trimming body 31, and rotatably supports the trimming body 31 via a bearing or the like, and the left bearing bracket 33a. The urging member 34 is provided around.

According to the illustrated example, the other shaft main body 32b is disposed on the right side of the trimming body 31 and is fixed integrally to the trimming body 31, and is rotated by a right bearing bracket 33a via a bearing or the like. It is supported so that it can move freely, and its tip end is connected to the speed reducer 35.

[0053] The urging member 34 is an elastic body such as a spring, for example, and one end side of the urging member 31 is fixed to the rivet body 31 so as to urge the rake body 31 in the winding direction relative to the shaft body 32a. In addition to being attached, the other end is fixed to one shaft body 32a.

Therefore, when the shutter curtain 10 is unwound from the holder 31, the upper end side of the flexible screen portion 11 is pulled upward by the biasing member 34, and the lower end side of the flexible screen portion 11 is the seat plate member 12. It will be pulled down by the weight.

Therefore, it is possible to maintain the flexible screen portion 11 in a stretched state with less stagnation when it is extended, and as a result, it is possible to maintain the closing property when the shutter curtain 10 is fully closed.

The urging force by the urging member 34 is set to be smaller than the force in the feeding direction due to the weight of the shutter curtain 10 (including the seat plate member 12). Therefore, the shutter curtain 10 can be automatically closed by its own weight, and can be opened by a relatively light operation.

The speed reducer 35 is connected so that rotational force is transmitted from the scraper 31 and is fixed to the outside of the bearing bracket 33.

The speed reducer 35 is configured to reduce the rotation of the shaft main body 32b by causing friction between the two members by the centrifugal force transmitted from the scraper 31, or by the viscous fluid friction of the other shaft main body 32b.
