Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is directed to a general-purpose combine harvester capable of capturing a plurality of grain culms by raising a plurality of grain culms and raising them with a case while cutting them. Includes auger structure.

[Conventional technology]

Conventionally, a plurality of grain culverts that are diagonally installed so as to be able to raise a plurality of grain culms facing each other and a retractable finger or spiral auger having a spiral are horizontally installed in the lower rear part of the case. In the mowing section of the constructed combine, as seen in Japanese Patent Application No. 1-85798 previously filed by the applicant, the part of the scraping auger that is the side of the side where the grain culms are raised and the case is raised is the center rear It had a structure in which a spiral was only wrapped around.

[Problems to be solved by the device]

However, when the grain culms that are raised by the side and raised by the case are taken in by the scraping auger, they are brought closer to the scraping finger side by the spiral, so that the grain stalks are partially taken in. As a result, the grain culms were stagnated, and the grain culms could not be fed smoothly from the cutting section to the threshing section.

[Means for solving the problem]

The present invention solves such a problem, and a plurality of grain culms facing each other in front of the sweeping auger (4) having the sweeping fingers (2) and the spirals (3a) (3b) that can freely move in and out. A plurality of grain culm raising cases (1a) (1a)
(1b) (1b), (1c) (1c) is extended to above the scraping auger (4), and lateral grain culm raising cases (1a) (1a), (1c) (1c) In the outer peripheral portion of the sweeping auger (4) which is located behind the sweeping finger (2) after being raised in the center, the laterally raised cases (1a) (1a), (1c) (1c) in plan view. ) It is configured to extend forward to the passage space of the grain culms to be formed between them.

[Action]

Therefore, when the grain culms are pulled up by the side grain culms and are raised by the case, they are mowed by the cutting blade, raised as they are, and sent to the center rear side, and are offset toward the center rear side finger and the scraping finger side. With the fingers, it is possible to take in immediately so as not to stagnate and send it out to the scraping finger side together with the spiral.

〔Example〕

 Next, an embodiment shown in the drawings will be described.

FIG. 2 shows a side view of the general-purpose combine, and the screw handling cylinder (8) is provided on the machine body supported by both crawlers (7).
The threshing section (B) containing the above is installed, and the rear part of the feeder chamber (C), which is continuously provided behind the mowing section (A) and houses the feeder (9), is provided in front of the threshing section (B). A second cutting blade (10) is provided below the feeder chamber (9) by being pivotally connected to and connected to each other.
Equipped with a hydraulic cylinder (11) to allow the cutting section (A) to move up and down, and a boarding operation section (D) on the side of the feeder chamber (C) and a side of the threshing section (B). Each side is equipped with a grain tank (12) and is constructed similarly to the conventional structure.

Further, the mowing section (A) has a scraping auger (4) horizontally rotatably driven inside the platform section (14) behind the first mowing blade (13), and Both auxiliary raising cases (16a) (16b) in which the tines (15) project and rotate forward are obliquely provided on both front sides of (13), and both auxiliary raising cases (16a) (16b) Within the cutting width, the two tines are raised in parallel so that each tine (17) faces each other to raise multiple culms.
a) (1a), (1b) (1b), (1c) and (1c) are installed side by side and obliquely installed, and each can be transmitted from the rear part of the reaper (A) by a transmission (18). The structure is the same as the conventional structure.

In the part of the scraping auger (4) facing the entrance of the feeder chamber (C) facing the rear of the center edge (o) of the both grain culvert raising cases (1b) (1b) which is the central side Is equipped with a plurality of sweeping fingers (2) that can freely move in and out, and spirals (3a) (3b) are provided from the part of the sweeping fingers (2) group to both ends of the left and right sweeping augers (4). ) Are attached respectively and are constructed in the same manner as the conventional structure, but the left and right side of the grain culm raising cases (1a) (1a) and (1c) (1c) are raised at the center edges (o) (o). Fingers (5a) (5b) for taking-in are fixedly provided on the outer peripheral portion of the scraping auger (4) which is located at the rear side, and as shown in FIG.
Incorporating fingers (6a) and (6b) are fixedly provided at portions offset from a) (5b) to the scraping finger (2) side.

Therefore, when the grain culm is raised by the case (1b) (1b), the grain culm is mowed by the cutting blade (13), is raised as it is, and is sent to the center rear, and the scraping finger (2) is provided.
Will be taken into the group.

In addition, the grain culm raising cases on both sides (1a) (1a), (1
c) Grain culms caused by (1c) are cut blades (1
Fingers (5a) (5b) on the rear side of the center when they are mowed by 3), raised and sent out to the center rear.
And the fingers (6a) and (6b) offset toward the sweeping finger (2), the swallowing finger (2) is immediately taken in so as not to stagnate, and the spiraling fingers (2a) and (3b).
Will be sent to the side, and all grain culms thus taken in will be fed into the feeder chamber (C) by the group of scraping fingers (2) and smoothly supplied to the threshing section (B). It will be.

[Effect of device]

In this way, according to the present invention, the grain culms that are raised by the side grain culm raising cases (1a), (1a), (1c) and (1c) are cut by the cutting blade and are raised as they are and sent to the center rear. And the fingers (5a) (5b) on the center rear side
And the fingers (6a) and (6b) offset toward the sweeping finger (2), immediately take in so as not to stagnate as in the conventional case, and together with the spirals (3a) and (3b), the sweeping finger (2) side It is possible to feed the whole of the multiple-row grain culms evenly and smoothly into the scraping auger, and the grain can be efficiently supplied to the threshing section. It has a feature that it can further improve the taking-in performance and can be suitably implemented with a simple structure.
