8e). The sub-frame (58s) defines a slidable hexagonal axis (58v) along the inner peripheral surface of the fixed sub-frame (58u) fixed to the left side in front view, similarly to the mowing frame (58). Variable sub-frame (58
t). In addition, the long reciprocating drive type cutting blade (23) is divided into two parts at appropriate positions, and one of the two parts is detachable or foldable. A cutting frame (58) supporting the scraping auger (24) and the cutting header (20).
And the like, slide the mowing header (20) in the machine width direction before the header (20).
It is designed to be stored and placed at an arbitrary position (not shown).

In the general-purpose combine equipped with the cutting header (20) having a large cutting width in the machine width direction as described above,
When the normal harvesting operation is completed and the combine is transported to the next field, the wide harvesting header (20) is displaced in the machine width direction according to the following procedure, and the header (20) is moved.
To reduce the size.

First, when the small-diameter tine bar (22a) of the scraping reel (22) is slid toward the inner peripheral surface of the large-diameter tine bar (22b), a plurality of brackets (22d) fitted to the tine bar (22a) are inserted. ) Are provided and concentrated on one end of the raking reel (22) (see FIG. 6). At this time, the wires (22e) provided between the raising tines (22c) are in a slack state. Next, the variable reel shaft (51a) integrally provided with a hexagonal shaft (51c) having a predetermined length is slid to the fixed reel shaft (51b) side to reduce the reel shaft (51) and reduce the scraper reel (22). ).

When displacing the scraping auger (24) in the machine width direction, the spiral (24c) inserted into the pin (24d) is removed manually or by using a tool or the like (see FIG. 7). The removed spirals (24c) are easily released from the small-diameter scraping auger (24a) due to the rigidity, and are loosely fitted to the large-diameter scraping auger (24b) while being loosely fitted to the auger (24a). The displacement of the scraping auger (24) is completed by causing the small diameter scraping auger (24a) and a plurality of released free spirals (24c) to slide and concentrate (FIG. 6).
reference).

Further, when the reaping frame (58) and the sub-frame (58s) are displaced in the machine body width direction, along the inner peripheral surfaces of the hollow fixed frame shaft (58b) and the fixed sub-frame (58u). Then, the variable frame shaft (58a) and the variable sub-frame (58t) integrally provided with the slidable hexagonal shafts (58c) and (58v) with a predetermined length are slid to predetermined positions, and the reaping frames (58) and The subframe (58s) is reduced in size.
In the above-described embodiment, the operation procedure of reduction is described in the order of the tine bar of the raking reel, the raking auger, and the mowing frame.However, the present invention is not limited to this procedure. It can be changed arbitrarily.

As described above, in a combine equipped with a squeeze reel, a squeeze reel, and a reaper header including a reaper frame supporting the reaper, the reaper header is stored when not in use. By using a double pipe for each part, it is possible to slide in the machine width direction with a simple configuration, contributing to quick downsizing.In addition, the displaced cutting header is unloaded from a truck or other loading platform and cut on a field etc. When performing an operation, a header with a wide cutting width can be easily obtained by the reverse procedure described above.

[0022]

As is apparent from the above embodiments, in a combine where the pre-cutting device can be raised and lowered with respect to the front portion of the combine by means of a lifting drive means, according to the first aspect of the present invention, the pre-cutting process is performed. Since the device is configured to be variable in the machine width direction, the entire harvesting pre-processing device can be displaced to a width at least equal to the machine width at the time of non-cutting work. This is useful for saving space when storing it on a loading platform or the like.
According to the second aspect of the present invention, since the scraping reel is configured to be slidable in the machine body width direction, it is possible to easily reduce the size with one touch. Furthermore, according to the third aspect, even a large scraping auger is configured to be slidable in the machine width direction, so that it is quickly compacted at the time of storage and is effectively used for saving space. In addition,
According to the fourth aspect, the mowing frame supporting the raking reel and the raking auger is configured to be slidable in the machine body width direction, so that the entire header having a wide mowing width can be downsized with a simple configuration. According to the fifth aspect, the raking reel, the raking auger, and the mowing frame that supports them are configured to be slidable in the machine width direction by a double pipe, so that a simple configuration by fitting pipes is provided. Therefore, the mowing frame that supports the raking reel, the raking auger, and the header can be reduced in cost and size.
