手段を設けてある点にある。[Features] A supply guide which is swingably switchable between an operation position where the harvesting culm from the mowing device is sandwiched by the conveyance start end of the threshing feed chain and a non-operation position retracted upward is provided. A hand-cuttered grain culm mounting support that can be switched between a storage position that exposes the section and a cover position that covers the transport start end is provided, and the hand-cooked grain culm is loaded as the supply guide switches from the working position to the non-working position. A lock that locks the supply guide to a non-operating position and releases the lock, wherein the mechanical support mechanism is provided to link the two so that the mounting support is reversibly switched from the storage position to the cover position. A lock means that can be switched between the released state and the released state is provided.

である。[Operation] According to the first aspect of the present invention, since the supply guide is fixed at the non-operating position and can be freely released by providing the lock means, the lock means is locked when threshing with the pillow. By switching, even if the hand-cut cereal culm placing support is unexpectedly operated from the cover position to the retracted position, the switching of the hand-cut cereal culm placing support to the retracted position can only be prevented. Instead, the supply guide can be held at the inoperative position. When the pillow handling threshing is completed, such as when shifting to a normal combine operation, and the supply guide needs to be positioned at the operation position, the locking means is switched to the release state, and the operation position of the supply guide is changed. It is possible to switch to.

をもって前記バネ３０を構成してある。As shown in detail in FIGS. 3 to 6, the locking means L is an automatic locking means which automatically switches to a locked state when the supply guide 15 is swung to a non-operating position. Means that the support arm 16 swings around the sixth left-right axis P6 in the non-operating position and engages with the engaging member 28 attached to the threshing apparatus main body 5A in a freely detachable manner. A lock engagement member 29 for holding the support arm 16 at the non-operating position is attached to the support arm 16, and an automatic lock spring 30 for oscillatingly urging the lock engagement member 29 to the engagement posture is provided. As the support arm 16 swings to the non-operating position, the locking arm 29 is pressed by the engaging member 28 so that the engaging portion 29a of the locking engaging member 29 rides over the engaging member 28 and engages. Locking engagement tool 29 And it is configured to form a cam surface 31 for swinging the disengaging position against the biasing force of the spring 30. Then, the end of the support rod 19 is engaged with a hole 29b formed in the lock engagement tool 29, and the support arm 16 is
Guide 15 for the support arm 16 of the support rod 19 by the sandwiching spring 20 in the state where is located at the non-operation position.
The locking engagement member 29 is interlocked so as to swing to the engagement posture by the movement to the side. That is, the holding spring 20
The spring 30 is configured as follows.

ている。According to the above configuration, by switching the supply guide 15 to the non-operating position, the locking engagement member 29 is automatically engaged with the engagement member 28 and the locking means L is automatically locked. In this state, as shown in FIG. 5, by pulling down the front end side of the supply guide 15, the supply guide 15 swings toward the side where the rear end side approaches the support arm 16 with respect to the support arm 16 and is supported. The rod 19 is pressed against the support arm 16 against the elastic force of the holding spring 20, and as a result, the locking engagement member 29 swings to the disengagement posture, and the engagement of the locking engagement member 29 is stopped. The engagement with the joining member 28 is released, and the locking means L is released. That is, the supply guide 15 is a release operation tool of the lock unit L.

However, the spring 30 is provided separately from the holding spring 20 for implementation. Is also good. In this case, the engagement is released by operating the locking engagement tool 29 itself, that is, the locking means L is switched to the released state.
