When the room cover 106 is opened in this way, almost the entire engine 13 is in a bare state, and at the same time, the space between the engine room 100 and the grain tank 7 is opened so that maintenance can be performed.

When only the upper cover plate 54 is opened without opening the engine room 100, the operating member 67 of the handle portion 66 is pulled forward against the elastic force of a spring (not shown). As a result, the operating member 67 is pivotally displaced in the direction opposite to the arrow h, and the notch j of the hooking state changing claw 73 is disengaged from the front-back direction portion of the hooking rod member 71a. Next, the upper cover plate 54 is pulled outward, whereby the hook members 72, 72 come out of the retaining rod member 71a and the coupling between the operating member 67 and the room cover 106 by the male and female coupling mechanism 68 is separated. The cover plate 54 has hinges 56, 56.
It is rocked around and opened. At this time, the lower cover plate 53 does not necessarily have to be removed. When the upper cover plate 54 thus opened is closed, the above-described operation at the time of opening is reversed.

When removing the entire upper cover plate 54 and lower cover plate 53 of the front-rear standing cover device 52, pull the upper cover plate 54 upward with the upper cover plate 54 opened as described above. To do. As a result, the hook members 60a and 60b and the locking plate member 65 are pulled out upward from the latch bar member 61a and the insertion pin member 64, and the front-rear upright standing cover device 52 is entirely removed from the machine body. Be done. To attach the upper cover plate 54 and the lower cover plate 53 thus removed to the machine body, first, the hook members 60a and 60b of the lower cover plate 53 are attached.
Then, the locking plate member 65 is fitted and inserted into the latch rod member 61a and the insertion pin member 64, and then the upper cover plate 54 is attached to the hinges 56, 5.
6 by swinging around and pressing the hook members 72, 72 into the notches of the hook members 72, 72 and the hook state changing claws 73, 73.
By fitting 1a against the elastic force of a spring (not shown), the upper part thereof is coupled to the room cover 106 via the hook members 72, 72, the hook state changing claws 73, 73 and the hook rod means 71a. As a result, the upper cover plate 54 and the lower cover plate 53 are attached to the machine body, and in this attached state, displacement in the up-down direction, the left-right direction, and the front-rear direction is restricted by the male and female engaging members 57 and the male and female coupling mechanism 68. Becomes

[0050]

According to the present invention configured as described above,
In addition to being able to prevent careless insertion of the body between the room cover and the grain tank, the appearance of the aircraft can be adjusted and the following effects can be obtained. The upright cover device can be easily held in position via the support rigidity of the room cover,
In addition, the room cover can be opened without being disturbed by the grain tank, and further, by opening the room cover, the front and rear facing cover device is not touched, so that not only the engine but also the room cover can be opened. A space between the grain tank in the normal position and the grain tank can be exposed.

According to the second aspect of the present invention, the space between the room cover and the grain tank in the normal position can be opened by separately removing the front-rear upright cover device, and the grain can be opened. Therefore, the grain tank can be easily swung without being disturbed by the front-rear standing cover device.

According to the third aspect, the outer portion of the space between the room cover and the grain tank in the normal position can be more completely enclosed by the presence of the lower cover plate.

According to the fourth aspect, the supporting force of the lower cover plate can be utilized for supporting the upper cover plate, and the lower cover plate and the upper cover plate can be handled integrally. Thus, the handleability of the front-rear standing cover device can be improved.

According to the fifth aspect, the front-rear standing cover device can be easily opened and closed and the structure can be simplified.
