[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting and conveying device for a multi-shed combine which can cut and transport grain stalks at a cutting section capable of cutting about six lines.

[0002]

2. Description of the Related Art Conventionally, in a multi-row cutting combine that is configured by extending left, right, and center lower transport chains rearward from the upper side of six star wheels arranged side by side above a cutting blade, for example, Japanese Patent Application No. 2-21 filed by the present applicant
No. 579, the starting ends of all lower transport chains were configured to be on the axis of each star wheel.

[0003]

However, in such a transport structure, when the length in the longitudinal direction from the star wheel to the junction of the lower and right lower transport chains is reduced,
Both lower transport chains always overlap on the adjacent star wheel and the wrap angle becomes large, so that the star wheel hinders the grain culm transport and wraps around the star wheel, the culm gets clogged, or the culm base If the lower transport chains do not overlap with the star wheel, the longitudinal length from the star wheel to the confluence of the lower transport chains will be longer, and the longitudinal length of the cutting section will be longer. Had a problem such as a longer time.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem and to make the reaping section compact and can be suitably implemented. For this reason, six star wheels are sequentially mounted. The start ends of the left and right lower transfer chains that engage with each other and can be driven from the rear so that the start end of the lower center transfer chain can be transmitted on the shaft of the star wheel on the center side and is suspended in a Y-shape. The left and right ends of the star wheels are displaced rearward from the axes of the star wheels and are drivable from the rear, respectively.
This is larger than the inclination angle of 3c.

[0005]

Accordingly, all of the plurality of star wheels can be driven to rotate by the central lower transport chain. When the cereal culm is transported rearward by the left and right lower transport chains, the cereal stem is added to the star wheel. Wraps around,
By operating the star wheel, it is possible to convey satisfactorily without clogging or uneven culm bases, and it is possible to shorten the length of the reaping portion in the front-rear direction.

FIG. 3 is a schematic side view of a cutting section in a six-row cutting combine, in which a rear portion of the cutting section A is pivotally supported 7 on a support section 6 of the machine body supported by both crawlers 5, and a cutting section is formed by a hydraulic cylinder 8. A is made up and down freely,
As shown in FIG. 7, the mowing part A is provided with vibration-proof rubbers 11 between the upper rear surface of each raising case 9 sloping forward and the drive case 10. As shown in FIG. 8, an anti-vibration rubber 14 is interposed between the lower rear surface of the cutting frame 12 and the stay 13 on the side of the cutting frame 12. The star wheels 2a to 2f are arranged side by side, and the star wheels 2a at both ends are provided.
2f, the lower transport chains 3a, 3b opposite to each other with the clamping rods 15, 16 extend in a Y-shape and extend rearward. 17, a lower transport chain 3c is provided to extend rearward, an upper transport tine 18 is provided above the left lower transport chain 3a, and an upper transport tine 19 extending from above the lower right transport chain 3b to the rear. Behind the vertical transport chain 20 that is connected to the rear side of the lower right transport chain 3b, an auxiliary transport chain 22 that inherits the culm of the grain culm is provided on the feed chain 21 of the threshing unit.

The six star wheels 2a to 2f are successively meshed with each other, and the starting end 4c of the central lower transport chain 3c projecting toward the middle of the left lower transport chain 3a is connected to the central right star wheel 2d. Upper coaxial sprocket 23
, And driven by a driving wheel 24 at the rear, the starting ends 4 of the left and right lower transport chains 3a, 3b.
a and 4b are mounted on idler wheels 25 and 26, respectively, which are suspended above the periphery of the star wheels 2a and 2f at the left and right ends, and are adjacent to the star wheels 2a and 2f.
The wings are extended rearward in a Y-shape with a wrap angle so as not to overlap with each other, and are configured to be freely drivable by rear drive wheels 27 and 28, respectively, as shown in FIGS. The inclination angle β of the lower transport chain 3a is made larger than the inclination angle α of the star wheel 2a, and the inclination angle α of the central and right lower transport chains 3c, 3b is the same as the inclination angle α of the star wheels 2b, 2e. Configure.

Accordingly, the six star wheels 2a to 2f
Are driven by a central lower transport chain 3c driven by drive wheels 24, and the left and right lower transport chains 3a, 3b are driven by drive wheels 27, 28, respectively, so that the adjacent two star wheels The grain stalks that are raked in between and cut are transported backward by the lower transport chains 3a, 3b, and 3c. However, since each of the chains does not overlap with the adjacent star wheel, the star wheel 2
b, 2c, and 2e, the culm is conveyed without being wound or clogged as in the related art, and the culm base is not evenly arranged.
The length of the machine body in the front-rear direction up to the confluence of a and 3b can be reduced, so that the reaper A can be made compact.

Since the vibration isolating rubbers 11 and 14 are interposed as shown in FIGS. 7 and 8, the noise generated from the raising case 9 is transmitted to the transport side of the cutting unit A and expanded as in the related art. In addition, since the inclination angle β of the left lower transfer chain 3a is set to be larger than the inclination angle α of the star wheel 2a, when the transfer chain is transferred to a transfer chain behind the lower transfer chain 3a, the culm base is reduced. It can be transported without shifting.

[0010]

As described above, according to the present invention, the grain stalks that are cut while being scraped by the plurality of star wheels 2a to 2f can be moved to the left and right and central lower transport chains 3a, 3b, 3c.
When transporting backwards, the star foils adjacent to each other will hinder grain culm transport, or cereal stems will be wrapped or clogged, and the culm base will be able to be transported in good order without becoming uneven, In addition, all of the plurality of star wheels can be driven to rotate by the central lower transport chain 3c, and the length in the longitudinal direction of the machine from the star wheel to the junction of the left and right lower transport chains 3a and 3b is reduced. As a result, the length of the reaper in the front-rear direction can be shortened and a compact structure can be achieved. And, since the inclination angle of the lower transport chain 3a on the left side is larger than the inclination angle of the other lower transport chains 3b and 3c, when the grain culm is transferred to the transport chain behind the lower transport chain 3a, the stem of the culm shifts. It can be conveyed so that it does not.
