Description

[Detailed Description of the Invention] The present invention is characterized in that a swinging arm interlocked with a reciprocating rod is fixedly connected to the center side in the width direction of the cutting blade, and a mower is attached to the upper part of the cutting blade for scraping the base of the culm. The present invention relates to a reaping device in which a star foil is provided, a culm stock base side conveying device is disposed behind the top of the star foil, and the reciprocating rond is provided to cross below the conveying device.

In the above-mentioned reaping device, the locking connection between the cutting blade and the swinging arm, the pivoting connection between the swinging arm and the cutting blade driving rond, and the swinging arm itself are Despite the fact that debris, grass, etc. are likely to get wrapped around the cutting blade, and the cutting blade driving rond is likely to interfere with the stock side of the conveying culm, causing posture disturbance,
At present, no consideration has been given to these matters.

In view of these circumstances, the present invention effectively prevents straw and grass from getting entangled by appropriately arranging the swinging arm, and
The purpose of the present invention is to suppress the disturbance of the posture of the conveying culm by a simple modification of the cutting blade driving rond. The lower part of the rond on the shell culm transporting path side of the source transport device is located below the line connecting both ends of the rond, and the swing arm is arranged below the star foil. It is characterized by

That is, by arranging the swinging arm at the bottom of the starwheel, the starfoil becomes an upper cover for the swinging arm, thereby protecting the swinging arm itself and the connections of the cutting blade and rond to the straw debris. It can effectively prevent the winding of straw, grass, etc., and the rotation of the star wheel can also be expected to actively remove straw, grass, etc., reducing drive loss caused by winding of straw, grass, etc. etc. can be suppressed.

By simply modifying the cutting blade driving rond by bending it into an inverted F-shape, it is possible to form a culm conveyance path with a large vertical interval between the rond and the culm root conveying device. It is possible to suppress the interference of the rond with the conveying culm, and to achieve smooth conveyance of the culm group in an orderly posture.By appropriately improving the arrangement of the swinging arm and by simply modifying the rond for driving the cutting blade, It has now been possible to eliminate all of the conventional drawbacks in one fell swoop.

Hereinafter, embodiments of the present invention will be explained based on the drawings.

In the figure, C is a 3-row combine harvester, and from the front, 3
A reaping device 4 consisting of a base pulling device 1A, IB, 1C, a reaping frame 2, a fixed receiving blade 3', a cutting blade 3 that can slide back and forth only in the left and right directions with respect to the receiving blade 3', and a threshing device. 5 are arranged one after another, and three star foils 6A, 6B are used to scrape the stock side of the culm.

6C, and a lower conveying device 7A that conveys the culm stock base side.

IB, and an upper conveying device 8A for conveying the shell culm tip side,
Equipped with 8B.

The reaping frame 2 basically has two vertical rods 2a and 2a' located on both sides of the fuselage, and a transverse direction (a direction transverse to the direction of travel of the fuselage) so as to interconnect these vertical rods at their front ends.
The cutting blade 3 is installed on the cutting blade stand 2b.

Immediately behind the cutting blade stand 2b, a support rod 9 is a vertical rod 2at2a.
The star foils 6A, 6B, 6C and the shell culm conveying device 7 are installed horizontally integrally with the support rod 9.
A, 7B, 8A, and 8B are supported (of which 7A and 8A are arranged behind the reference side pulling devices IA and IB, facing almost the same direction as the direction of movement of the aircraft. , 7B and 8B extend from the rear of the opposite lifting device 1C and are disposed so as to merge with the conveying devices γA and 8A, respectively, and are scraped by the star foils 6A, 6B and 6C. The above-mentioned conveying devices 7A, 7 are arranged in two rows in an upright state.
The culms conveyed by B, 8A, and 8B are combined into a line at the merging point P, and then conveyed to the rear.

Between the shell culm conveying device and the threshing device 5, a lifting conveying device 11 is installed at a position that connects the feed of the threshing device 5 and the starting end of the chain 10 immediately after the confluence P.

Next, to explain the drive device for the cutting blade 3 of the reaping device 4, as shown in the first frame and FIG. 13 is provided to be able to swing back and forth around a shaft 20, and a pin 21 on one end side of the swing arm 13 is engaged and connected to a U-shaped engagement portion of an engagement member connected to the cutting blade 3. At the same time, a rod 12 that crosses below the culm stock base side conveying device 7B is pivotally connected to the other end side of the swing arm 13, and the base side of the rod 12 is pivotally connected to the crankshaft. Therefore, the swinging arm 13 is reciprocated by the reciprocating movement of the rod 12 in the axial direction as the crankshaft rotates, and the mowing arm 13 is reciprocated in the left-right direction along with the swinging. Then, the cutting blade 3 and fixed blade 3' cut the base of the planted culm.

As shown in FIG. 2, the cutting blade driving rod 12 is formed into a substantially inverted F-shape in side view, and the rod 12 is provided at the lower part of the culm conveying path side of the culm base side conveying device IB. A portion of the rod 12 is located below a line connecting both ends of the rod 12, and a vertical distance between the rod portion and the culm base side conveying device is configured to be large, so that the rod portion is located below the line connecting both ends of the rod 12. The aim is to avoid interfering with stockholders as much as possible.
