Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a combine, which is a combiner 1 for cutting a stalk and culm, a threshing section 3 for threshing a cut stalk and selecting threshed grains, and a threshing-treated drain. A post-processing section 4 for discharging the culm, a crawler-type running section 5 and the like are provided, and all of these basic configurations are conventional.

Reference numeral 6 denotes a feed chain with a claw that is hung in the front-rear direction on the side of the threshing unit 3. The feed chain 6 has stems and culms supplied from the cutting unit 2 arranged side by side upward. It is transported toward the threshing unit 3 while being sandwiched between the pinching rails 7 to be formed. However, above the starting end of the feed chain 6, an open space in which the pinching rails 7 are not juxtaposed is secured. As a result, the supply of stems and stems by hand is allowed.

Reference numeral 8 denotes a stem / culm pressing member disposed above the starting end of the feed chain 6 for carrying the feed chain 6.
A configuration including a stem-culm pushing rod 18 described below, which is located on the sending start end side
However , the stem culm pressing body 8 has a pressing posture in which the feeding stem culm of the mowing part 2 is pressed and clamped close to and opposed to the feed chain 6, and a non-pressing posture which is separated from the feed chain 6 and allows manual operation. It is configured to be able to transform freely. That is, a bracket 9a is integrally provided at the starting end of the rail frame 9 that supports the clamping rail 7, and the base plate 11 of the stem and culm pressing body 8 is moved up and down on a support shaft 10 that is supported by the bracket 9a. Although it is rotatably connected, furthermore, between the bracket 9a and the stem culm pressing body 8, a
2 are provided, so that the stem / culm pressing body 8 is held in the above-mentioned two positions in a resilient manner. Reference numeral 13 denotes a lower limit stopper screw which locks the stem / culm pressing body 8 at the lower limit position and finely adjusts the lower limit position.
Is an upper limit stopper piece for locking the stem / culm pressing body 8 at the upper limit position.

Reference numeral 14 denotes a projecting plate projecting forward from the base plate 11 and having a substantially U-shaped cross section.
A round hole 14a for penetrating and supporting the rear slide shaft 15 so that the rear slide shaft 15 can slide up and down is formed in the vertical position on the base end side of the projecting plate 14, while the front side vertical position of the projecting plate 14 is An elongated hole 14b is provided to penetrate the slide shaft 16 so as to be vertically slidable and to allow the slide shaft 16 to swing back and forth. At the lower end, the stem and stem pressing rods 18 are respectively connected via pivot pins 17.
The front and rear position is pivoted. That is, the stem and stem pressing rod 18 pivotally supported by the front and rear slide shafts 15 and 16 is opposed to the starting end of the feed chain 6 based on the sliding of the front and rear slide shafts 15 and 16 in the same direction. While being slid up and down, it is possible to swing and change to a forwardly inclined or backwardly inclined posture based on the reciprocal slide of the front and rear slide shafts 15 and 16 or one of the slides.

[0008] Furthermore, 19 shall apply the pressing bullet machine for biasing toward said stem稈押pressure rod 18 to Fuidochien 6, pressing圧弾machine 19, the base end portion of the longitudinal slide shaft 15, 16 Each slide shaft 1
The front and rear positions of the stem / culm pressing rod 18 are urged via the fifth and the sixth. In other words, the stem stalk pressing rod 18 that is slidable in the vertical direction and swingable is urged by the plurality of pressing rams 19 arranged in the stem stalk transport direction. Can be pressed substantially uniformly regardless of the increase or decrease of the supply amount. In addition, the biasing position of the front-side pressing machine 19 substantially coincides with the arrangement position of the star wheel 20 for scraping the stem to the feed chain 6 in a side view, so that the scraping ability of the star wheel 20 is increased. You can do it.

By the way, in this embodiment, the urging force of the pressing ram 19 is set to be larger than the urging force of the fulcrum exceeding the fulcrum 12. That is, when the supply stem culm from the reaping unit 2 increases, the entire stem culm pressing body 8 retreats and rotates within a range not exceeding the fulcrum to avoid clogging of the stem culm. When the number increases, the stem / culm pressing body 8 automatically crosses the fulcrum to avoid an abnormal load.

On the other hand, the clamping rail 7 is formed by connecting a plurality of rail pieces 7a in a series, and is supported by the rail frame 9 via a slide shaft 23 urged by a pressing elastic machine 22. For this reason, each rail piece 7a is slidable in the vertical direction and swingable, but a hook-shaped engaging rod 24 is integrated with the rail piece 7a at the transport start end toward the front. It is projected. The engaging rod 24 is protruded from the base plate 11 when the stem and culm pressing body 8 reaches a position near the fulcrum when the stem and culm pressing body 8 is transformed into the non-pressing posture. In addition to engaging with the mating pin 25, the rail piece 7a at the transport start end is separated from the feed chain 6 following the stalk squeezing body 8, and then transformed from the pinching position to the handling position with the transport start end open.
And it is linked to hold .

In the middle portion of the engaging rod 24, there is formed an inclined side 24a having a front height and a rear low shape.
4a is continuous with the inclined guide surface 7b formed at the front end of the rail piece 7a, thereby facilitating the introduction of the stem and culm during the manual handling operation, and at the same time, forming the The inconvenience of stems and stems entering between them can be eliminated.

[0012] In embodiments of the present invention constructed as narrative, when performing hand扱作industry, but will be Hensugata stalk稈押pressure body 8 in the non-pressing position, the stem稈押pressure body 8 When the deforming operation is performed, the engaging pins 2 protruding from the base plate 11 are formed.
5 engages with an engaging rod 24 provided at the starting end of the clamping rail 7 and lifts it.
Part of the rail piece 7a is automatically separated from the feed chain 6 and transformed into a handling position in which the transport start end side is opened, and
Will be retained . Therefore, when introducing the stem manually between the feed chain 6 and the sandwiching rail 7,
The introduction section is widened, and the introduction work of the stem / culm becomes easy, so that the workability in the manual handling operation can be improved .

In addition, the rail piece 7a at the starting end of the transport of the clamping rail is automatically transformed into the widening position in accordance with the transformation operation of the stem / culm pressing body 8 , and is held in this position. There is no need to particularly change the shape of the strapping rail 7 and maintain the posture, and as a result, it is possible to simplify the preparations for the manual operation and improve the workability in the manual operation.

Further, since an inclined side 24a is formed in the middle of the engaging rod 24, which is continuous with the guide surface 7b of the rail piece 7a, the introduction of stems and stems during manual handling is further facilitated. As a result, the inconvenience of stem stalks entering between the pinching rail 7 and the stem stalk pressing body 8 can be eliminated.

Further, when the stem-and-culm pressing body 8 is moved to the non-pressing position, the engaging rod 24 is moved to the engaging pin 25 when the stem-and-culm pressing body 8 reaches a position near the fulcrum. Because of the engagement, there is no inconvenience that hinders the evacuation rotation of the entire stem and stem pressing body 8 described above.
