SUMMARY OF THE INVENTION The present invention relates to a combine as described in the preceding paragraph, wherein a control section is provided on a side of a harvesting and transporting section provided in front of a threshing section. Is covered with the front and rear of the dust cover, and the rear of the closed dust cover is moved forward to cover the dust cover.
It is intended to provide an opening / closing means which is displaced upward to the front to be in an open state, and which can easily and rationally perform an opening / closing operation after the dustproof cover.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention covers the upper part of a mowing transport section provided in front of a threshing section with a dustproof cover before and after a dustproof cover. An operation member which moves forward and is displaced upward in front of the dust-proof cover to open the lock member, the operation of releasing a lock member for locking in a closed state after the dust-proof cover, the operation member mounted on the back of the dust-proof cover. The operation member serves as a handle for the opening operation after the dust cover, and the lock in the closed state is obtained by operating the operation member forward. Since it is released, it moves forward with the release of the lock, and becomes an open state, so that it can be easily moved forward after the dustproof cover.

Further, in the open state in which the dust cover is moved forward after the dust cover, the lock in the open state is also used by a lock member that locks in the closed state, so that the number of parts is reduced and the structure is simplified. Become.

Further, since the release operation of the lock member for locking the rear of the dust cover in the open state is interlocked with the operation of the rear side of the operation member, the operation member can be operated rearwardly. The lock in the open state is released, and when the lock is released, it moves rearward to the closed state, so that the rearward movement after the dust cover is facilitated.

[0007] Further, by providing the means for moving forward after the dustproof cover inside the left and right sides behind the dustproof cover, the step between the front of the dustproof cover and the rear of the dustproof cover is reduced. As a result, the height after the dust cover is reduced, whereby the operation member can be easily operated and the movement after the dust cover is smooth.

[0027]

The present invention is embodied in the form described above, and has the following effects.

The upper part of the mowing and transporting part provided in front of the threshing part is covered with a dust-proof cover before and after the dust-proof cover, and the rear part of the closed dust-proof cover is moved forward to cover the dust-proof cover. In which the locking member that locks in the closed state after the dust cover is linked to the operation of the front member of the operation member attached to the rear of the dust cover. , The operating member is dustproof
It becomes a handle for the later opening operation, and furthermore, the closed member is unlocked by operating the operating member to the front, so that it moves forward with the unlocking to open and becomes open. Can be easily moved forward.

In the open state in which the dust cover is moved forward after the dust cover, the lock in the open state is also used by a lock member that locks in the closed state, so that the number of parts is reduced and the structure is simplified. It can be provided at low cost.

Further, since the releasing operation of the lock member for locking the rear of the dustproof cover in the open state is linked to the operation of the rear side of the operation member, the operation member can be operated rearwardly. The lock in the open state is released, and when the lock is released, it moves rearward to the closed state, so that the rearward movement after the dust cover can be easily performed.

Further, by providing the means for moving forward after the dust cover to the inside of the left and right sides after the dust cover, the step between the front of the dust cover and the rear of the dust cover is reduced. As a result, the height after the dust cover is reduced, the operation member can be easily operated, and the movement after the dust cover is smooth.
