Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a structure of a cutting part of a combine with all culms.

[Conventional technology]

The whole culm input type combine as described above sends the cut culm directly into the dehulling device. That is, since the granulated portion of the shell culm and the unnecessary stem culm are fed into the shelling apparatus, the stem culm may adversely affect threshing and sorting, or may increase the threshing load.

In view of this, there is, for example, one provided with a reaping unit as disclosed in Japanese Patent Application Laid-Open No. 1-256312. That is, the vicinity of the root of the planted husk culm in the field is first cut by a clipper-type wide first cutting device ((13) of the above-mentioned publication). Then, the cut culm is sent to the rear as it is, and a second cutting device ((1.
4) Cut the lower side of the grained part of the husk culm. After that, the cut stems are dropped to the field, and only the granulated part is sent into the shelling apparatus.

As described above, unnecessary stems and stems are cut off before being sent into the threshing apparatus, and only the granulated portion is sent into the threshing apparatus, thereby suppressing an adverse effect on threshing and sorting and an increase in threshing load.

[Problems to be solved by the invention]

In the above-described configuration, the shell culm of each strip cut by the first cutting device is sent almost directly behind, and the lower side of the granulated portion of the shell culm is cut by the wide second cutting device. The stems thus dropped fall into the field over a wide range extending across the left and right widths of the second cutting device. Therefore, a pair of left and right traveling devices located behind the cutting unit step on the stems and stems that have fallen into the field.

Particularly in wet fields, if a long stem culm is pushed into the ground by the traveling device, the stem culm cannot be sufficiently collected after the mowing operation. If the stalk culm is kept pushed into the ground, when the tilling work is performed thereafter, the stalk culm becomes entangled with the tilling device, which hinders the tilling work.

It is an object of the present invention to obtain a configuration in which a cut stem and culm cannot be trampled on a traveling device in an all-culm input combine equipped with the first and second cutting devices as described above.

[Means for solving the problem]

The feature of the present invention resides in that the harvesting unit is configured as follows in the above-mentioned all-culm input combine.

A first cutting device for cutting the vicinity of the root of a plurality of planted shell culms, and a shell culm cut by the first cutting device, a plurality of hulls, which are cut between the pair of left and right traveling devices in the cutting unit, A first transport device that transports and collects via an introduction path;
A second cutting device that cuts the lower side of the granulated portion of the shell culm collected by the first transport device and drops the cut stem culm between the traveling devices; and a stem culm in the second cutting device. And a second transporting device for feeding the granulated portion having been cut into the threshing device.

[Action]

When the mowing part is configured as described above, the vicinity of the root of the planted husk culm in the field is first cut by the first cutting device. Then, the cut culm is sent and collected via a plurality of introduction paths to a portion located between the pair of left and right traveling devices by the first transport device, and at the collected position, The lower side of the grained portion of the shell culm is cut by the two cutting device. As a result, the cut stems are dropped between the pair of left and right traveling devices, and the granulated portion is fed into the threshing device by the second transport device.

[Effect of the invention]

As described above, by configuring the cut stems to drop between the pair of left and right traveling devices, the left and right traveling devices will not be able to step on the stems and culms that have fallen into the field, so that the stems and culms to be performed later can be used. Recovery becomes easier. This allows
There will be no hindrance to the tilling work. In this case, the conventional advantage that only the grained portion of the husk is fed into the threshing apparatus remains.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in FIGS. 3 and 1, the body supported by a pair of left and right crawler-type traveling devices (1a) and (1b) is driven to rotate around an axis (P) in the longitudinal direction of the body. Body (2)
And a cutting unit (4) at the front of the fuselage to constitute an all-culm input combine.

Next, the reaper (4) will be described. FIG. 1 and FIG.
As shown in the figure, this mowing part (4) is of a six-row type, with seven sets of dividers (5) and six sets of raising devices (6).
It has. In addition, a clipper-type wide first cutting device (7) for cutting the vicinity of the root of the planted husk culm raised by the raising device (6) is provided, and a rotary type for scraping the cut hull culm is provided. Packer (8) is provided.

On the other hand, a pair of left and right disc-type second cutting devices (9) is provided at the portion between the left and right traveling devices (1a) and (1b) behind the first cutting device (7) in the reaper (4). Is provided. Then, the holding and transporting device (10) (corresponding to the first transporting device) which clamps the lower side of the grained portion of the shell culm cut near the root and sends it to the second cutting device (9), and The locking transport device (11) (corresponding to the first transport device), which pushes the granulated portion of the shell culm transported by the nipping transport device (10) with a claw, is located at the right of the cutting section (4), at the center of the two strips. Article 2 and left 2
Provided in each of the Articles, multiple introduction routes (R1), (R2)
Is formed.

With the above-described configuration, the shell culm, which has been cut in the vicinity of the root by the first cutting device (7), is held by the holding and conveying device (10) with the lower side of the granulated portion held therein, and the plurality of introduction paths (R) are held.
1) and (R2) are conveyed so as to be gathered to the second cutting device (9) side. Then, the collected shell culm is cut by the second cutting device (9) at the lower side of the granulated portion. Thereby, the cut stems and stems are obtained from the second cutting device (9).
As shown in FIG. 1, it falls between the left and right traveling devices (1a) and (1b). The second cutting device (9) is configured to be vertically adjustable in height.

On the other hand, the granulated portion conveyed by the locking and conveying device (11) is cut from the stem and culm by the second cutting device (9), and is then moved from each locking and conveying device (11) to the second cutting device (9). While being fed onto the rear guide plate (12), it is scraped by the rotationally driven drum (13). Then, the granulated portion is sent from the drum (13) to the threshing device (3) by the feed conveyor (14) (corresponding to the second transport device). Straw chips coming out during threshing and sorting in the threshing device (3) are discharged to the field from the rear of the threshing device (3). In this case, the left and right traveling devices (1a), During (1b), that is, from the second cutting device (9) of the cutting unit (4), straw chips are discharged onto the stems and stems dropped on the field.
