Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain culm rake device for a combine harvester.

Prior Art and Problems to be Solved by the Invention A grain culm raking reel is provided on the upper side of the front part of the cutting blade device, and as the raking reel rotates, the grain culm raking reel disposed around the periphery is used to remove the grain in front. Grain culms are harvested by engaging the culms and scraping them into the side frame wall of the rear cutting blade device. .

Since there is a gap between the raking tines at both the left and right ends of the raking reel and the side frame wall, the culm can be raked in smoothly.
In the left and right side frame walls, the grain culms being raked are not well separated from the grain culms on the uncut side, making it difficult to reliably rak the grain culms to be raked into the inside of the side frame walls. There was a problem that it could not be done and it would stick out to the outside.

Therefore, this invention improves the culm raking performance by providing a raking body that slides on the inner surface of the side frame wall so that there is no gap between the left and right ends of the raking reel and the side frame wall. The purpose is to achieve this goal.

Means for Solving the Problems The present invention provides a grain culm raking reel (2) which is provided with raking tines (1) for engaging and raking the grain culm on its rotating periphery. The side frame wall facing the outside of the culm raking reel (2)
3) The structure of the grain culm raking device for a combine is provided with a raking body (4) that comes into sliding contact with the inner surface of the grain culm raking device.

The working grain culm of the invention is the raking tine (of the rotating grain culm raking reel (2))
1) and is raked inside the left and right side frame walls (3), but the culm raking bodies (4) provided at both left and right ends of the grain culm raking reel (2) The reel (2) rotates in sliding contact with the inner surface of the side frame wall (3) facing the outside, and the grain culm on both left and right ends of this grain culm scraping reel (2) is rotated on the inside of the side frame wall (3). being pushed into.

Effects of the Invention Therefore, since the scraping body (4) eliminates the gap between the left and right ends of the grain culm scraping reel (2) and the opposing side frame wall (3), the inner side at the side frame wall (3) portion is eliminated. Grain culms being raked into the culm are reliably separated from grain culms on the uncut side by the raking body (4) and raked inside the side frame wall (3), thereby improving raking performance. At the same time, the rearward conveyance performance can also be improved.

Example: On the same side, the combine harvester has left and right traveling devices (6
) on a chassis (7) with a handling cylinder (8) and a sorting device (
It is equipped with a threshing device (1) equipped with a threshing device (1 [9), etc., a reaping device (1υ) is installed in the front part so that it can be raised and lowered by the extension and contraction of a lifting cylinder (12+), and a threshing device (II) is installed on the side of the threshing device (II) on the chassis (7). The grain tank f13 has a structure in which a cabin containing a pilot's seat is provided on the front side thereof. (19 is a grain discharge auger for taking out grains from the grain tank (13).

The reaping device [flll has a pair of left and right grass cuttings flG at the tip.
l is supported by the dividing rod (Gong), and the left and right dividing rods (
A cutting blade device (IEI) is provided at the rear over a distance between
1 has been established.

' At the rear of the cutting blade device + IEI, a pair of left and right screws (+91 and auger I21 provided with a plurality of fingers G protruding from the outer circumferential surface of this cylinder) with different feeding directions are installed on the outer circumferential surface of the cylinder in the cutting width direction. , and is mounted on the left and right side frame walls (3). Qδ is a bottom plate provided below the auger Ql) and having a conveying surface.

Behind the auger (21), a rear threshing device (1o
A conveying device 24 is provided for conveying the liquid to the first supply port (to).

On the upper side of the front part of the cutting blade device 0, there is a raking tine (1) on the rotating periphery that engages and rakes the grain culm while rotating four times around the horizontal reel axis along the cutting width direction. The grain culm scraping reel (2) is supported by a reel arm 4, and is configured to be vertically movable around the horizontal axis (2) by expansion and contraction of a hydraulic cylinder (5).

The grain culm raking reel (2) has a pair of frames fixed to the left and right sides of the reel shaft 4, and the frames fix the bases of a plurality of arms OI to the outer peripheral surface of the reel shaft 4. The arms are arranged radially, and the distal ends of each arm are connected by a reinforcing arm OD to form a polygonal shape when viewed from the side. The tip ends of the left and right arms are connected to each other by a reel slat, and a scraping tine is provided at a position facing the inside of the left and right side frame walls of the reel slat. 1
), and a scraping body (4) that slides into contact with the inner surface of the side frame wall (3) facing the outside of the grain culm scraping reel (2) is provided at both left and right ends of the reel slat (support). ing.

The scraping body (4) is made of an elastic body.

Frame I2 on the − side! On the outside of the reel slat (
6. The scraping body (6) is provided with an angle adjustment device (B) for adjusting the ground angle of the scraping tine (1) by interlockingly rotating the scraping body (1).
4) has a configuration in which the ground angle is adjusted in conjunction with the scraping tines (1).

When the left and right traveling devices (6) are transmission driven to perform cutting and harvesting work, the grain culms are raked by the splitter body (old), and the tips of the grains are moved by the raking tines of the rotating grain culm raking reel (2). 1) and is scraped into the left and right side frame walls (3), and the stock base is harvested by the cutting blade device 0. This cut grain culm is moved by the auger 2
1) Screw (■) is pushed toward the center.

The grains are sent to the conveyance path by the fingers 12 (I), lifted up and conveyed by the conveyance device Q4, and supplied to the threshing device (11), where they are threshed.

In this reaping work, the grain culm scraped by the grain culm raking reel (2) is removed from the side frame wall (3) at the side frame wall (3).
) The grain culm is scraped into the side frame wall (3) by the scraping body (4) which rotates while slidingly contacting the inner surface of the grain culm. Also, this scraping body (
Since the raking tine (4) rotates at the same angle to the ground as the raking tine (1), on the upward side of the rotation direction, the raking action on the grain culm escapes, and the grain raked by the raking body (4) Grain culms are reliably raked inside the side frame wall (3) without rolling up the culms, and good reaping work can be performed.
