In the general-purpose combiner having the above-described structure, a wide-range mowing provided with an uncut culm scraping reel (22), a reciprocating drive type cutting blade (23) and a scraping auger (24). The header (20) has a high efficiency in a large plot field and improves work efficiency. However, when the combiner is stored in the truck bed when the combine is not used, the width of the harvesting header (20) in the machine width direction is too large. Inconveniences such as securing of space and loss of storage work time occur. Therefore, in the present invention, as shown in FIGS. 4 to 7, the cutting header (20), which is a pre-cutting device, is configured to be variable in the machine width direction.

FIG. 4 is a front view of the mowing header.
FIG. 5 is an explanatory view showing a displaced state of the mowing header, FIG. 6 is a front view showing a state where the mowing header has completed displacement, and FIG. 7 is a side view showing a state where the mowing header has completed displacement. The tine bar of the scraping reel (22) is formed of a double pipe having different inner and outer diameters, and is fitted into the small diameter tine bar (22a) with a small diameter. (22d) is attached via a bracket (22c). On the other hand, the large tine bar (22b) having a large diameter raises the tine (22b).
d) is fastened, but the large-diameter tine bar (22)
b) has a fixed length in the machine width direction and a small-diameter tine bar (22) along the inner diameter of the large-diameter tine bar (22b).
a) functions so as to be slidable, and is configured to be housed to a position approximately 1/2 of the right side when viewed from the front.

The scraping auger (24) is approximately 1/3 on the right side when viewed from the front.
The right rake auger (24a) and the left rake auger (24b) are divided into two parts.
(24b) is a cutting frame (5
8) The reinforcing support rod (24) is provided via a rotation support member (24c) laid across the upper horizontal frames (58a) (58b).
d). The upper horizontal frame (58
A hydraulic cylinder (73) is provided at an appropriate position in b),
A telescopic piston rod (73a) is fitted into the cylinder (73), and the rod (73a)
One end (74) of a V-shaped link (74) provided at the tip of
a) is on the right scraping auger (24a), and the other end (74b) is on the upper horizontal frame (58a) of the left scraping auger (24b).
(58b). In addition, the reciprocating cutter blade (23) is a reciprocating cutter blade (23a) (24).
b), and the driving source is a header input shaft (39) via a crank arm (41), a crank rod (42) and a drive arm (43) as shown in FIG.
The left and right ends are connected to the left and right forward drive type cutting blades (23).

In the general-purpose combine having the cutting header (20) having a large cutting width in the machine body 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) cannot be stored in the truck bed or the like in the same state,
According to the following operation procedure, the mowing header (20) is displaced in the machine width direction to reduce the width of the wide header (20), thereby contributing to saving storage space and speeding up the transport movement.

First, when the small-diameter tine bar (22a) of the scraping reel (22) is slid toward the large-diameter tine bar (22b), a plurality of brackets (22c) inserted into the tine bar (22a) are used. The raised tine (22d) provided is concentrated and held at one end of the raking reel (22) (see FIG. 5). Next, the hydraulic cylinder (73) that supports the V-shaped link (74) fixed to the upper horizontal frames (58a) and (58b) of the two-piece mowing frame (58) is pulled or extended. When the piston rod (73a) of the hydraulic cylinder (73) is shortened,
The tip of the left upper side frame (58b) of the rotating member (24c) straddling the left and right sides is used as a pivot (75).
The right scraping auger (24a) rotates counterclockwise, and is finally turned 180 degrees and placed on the upper horizontal frame (58b) on the left scraping auger (24b). Also, since the long reciprocating mowing blade (23) is divided into left and right parts in advance, it can be used together with the mechanism related to the scraping auger (24a).
It is placed in a state where it is inverted by 0 degrees (see FIGS. 6 and 7). Note that the procedure for displacing the mowing header (20) is not limited to the above-described operation procedure, and can be changed as appropriate.

As described above, the tine bar of the raking reel formed by the fitting of the double pipe is slidably operated, so that the raking reel can be quickly expanded and contracted with a simple structure. Also, one of the two broadly divided scraping augers,
With a simple operation of a single hydraulic cylinder, it can be folded and placed on the upper surface of the other augment auger by being turned 180 degrees, thereby saving storage space. Further, since the long reciprocating cutting blade is divided into right and left, it can be easily folded and contributes to reduction of vibration of the cutting blade during driving. In addition,
When the displaced cutting header is lowered from a loading bed such as a truck and the like, and cutting is performed in a field or the like, a header having a wide cutting width can be easily obtained by the above-described reverse method.

[0016]

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. Because the device is configured to be variable in the machine width direction, the entire wide pre-cutting device can be folded to a width equal to or less than the machine width during non-cutting work, so that the truck is compact and has a truck bed. It is useful for saving space when storing in e.g. 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 can be easily stored with one touch. Furthermore, according to the third aspect, the scraping auger of the pre-cutting device is configured to be foldable via the hydraulic cylinder, so that the scraping auger can be quickly removed by a simple mechanism.
Can be folded 80 degrees. Further, according to the fourth aspect, the long cutting blade of the cutting pretreatment device is divided into right and left, so that the cutting blade can be easily folded and is effective in reducing the vibration of the cutting blade when driven.
