Description

[Detailed Description of the Invention] The present invention is to rotate a pre-processing section formed by a culm lifting device, a reaping device, a reaped culm rear conveyance device, etc. around an axis with respect to a machine body equipped with a threshing section. '0T capacity and pretreatment a
This invention relates to a combine harvester configured to move up and down.

In such a combine harvester, when the pre-processing section is rotated around the horizontal axis with respect to the machine body, the cut husk rear conveyance device of the pre-processing section and the fC feed chain installed in the threshing device mounted on the machine body are connected. There are intercusps where the relative posture changes and the delivery posture of the stem culm tends to be disturbed.

As a means to solve this problem, it is possible to arrange a clamping rod under the chain with protrusions and insert the clamping rod under the terminal end of the stock transfer device, but such a method is not possible. In this case, the clamping rod must be inclined almost equally to the rear-upward slope of the stock transfer device, so that the culm delivered from the stock transfer device onto the clamping rod tends to slip. , the problem arises that it is difficult to carry out the delivery smoothly.

Therefore, in order to prevent the grain culms from slipping on the clamps, if the chain with protrusions is extended toward the stock conveyor side and the grain culms are clamped at an early stage, the extended chain with protrusions can be seen from the side. As a result, the culm transported by the rear conveyor must be horizontally laid down at an early stage, and as a result, when it suddenly falls sideways, it exerts a squeezing effect on the tip of the head. Grain shedding is more likely to occur.

The present invention aims to solve these problems all at once, and the present invention aims to improve the configuration of the feed chain of the threshing device and the starting end of the feed chain for the grain conveying device of the pre-processing section that rotates around the horizontal axis. By partially rationalizing the
It is an object of the present invention to provide a combine harvester that can smoothly inherit cutting husks regardless of changes in relative posture with respect to a feed chain.

Hereinafter, the invention will be explained in detail based on examples.

Traveling device [11] At the front of the threshing section (2) provided at the top, there are a lifting device (3), a reaping device (4), a horizontal conveying device (5), and a two-tiered reaped husk culm conveying device. 16) connected to the support frame (7) to construct a self-propelled combine harvester (9), the culm supply port (10) of (2) ) is located at the front and slightly lower side of the threshing part (2
) is mounted on a horizontal shaft, and the rear end of the reaping supply support frame (7) is connected to the rotation shaft 1111.
A pair of bevel gears i, +21 are rotatably fixed around the core (P), and a pair of bevel gears i, +21 are installed in this reaping supply support frame (7).
, A rotary transmission shaft circle interlocked with the rotation @till is installed via J21, so that the r of the curved end of support #(7)
A pair of bevel gears 1J4) are installed near the end of the giant horizontal rotating shaft (11) to drive the harvesting device (4), the horizontal conveyance device (5), and the lifting device (3). Gauging (with internal transmission axle load 5) linked via
The beak is rotatably attached around the rotation axis (P), and this transmission 1 [11t161 is configured to drive the harvested husk conveying device (6) to the threshing section (2). It is. On the other hand, the reaping supply support frame (7) is positioned so that the relative seating position can be changed, and the reaping culm conveying device (6)
By changing the relative posture of the threshing section (2) with respect to the support frame (7), the supporting position for the grain culm that has been harvested and fed laterally is changed.
)'s feed chain:/! Adjustment of the attitude of transferring the grain culm to the 2I+ and adjustment of the handling depth are performed. (4) In one embodiment of the above-mentioned structure, the feed chain 1) is sandwiched between the chain with protrusions (21a) nFf
(glb) is configured in an underchain type disposed on the −[ side, and the starting end side Jf of this protruded chain (2ia) is
The stock carrier (6a) VC extends diagonally upward and forward with a gentle slope toward the front bridge side of the AT processing section (8), and is inclined upwardly at the rear of the harvested grain culm rear conveyance device (6). While tilting in parallel, in side view, the feed chain starting end (21c) is located between the stock base conveyor (6a) and the rotation axis axis (P) of the preprocessing section support frame (7), and , the feed chain start end (21) is inserted into the stock base conveyor (6a) by an appropriate length in the front-back direction, and the feed chain starting end (21
It is configured to wrap in the front and back direction with respect to the end @ Miyako (6b).

Therefore, the pre-processing section (8) is positioned at the axis (1') relative to the aircraft body.
), the starting end (21c) of the feed chain (2υ is the end of the stock transporting device) even if the attitude of the feed chain (2υ is changed to (6b), the feed chain (21) VC smoothly inherits the cut culm from the stock carrier (6a) regardless of whether the pretreatment section (8) is up or down. It is.

In summary, the combine harvester according to the present invention has a threshing section (2)
The feed chain (2υ) is an underchain type, and its starting end extends obliquely forward and upward toward the curved end side of the single-mouth processing section (8), and when viewed from the side, the feed chain (2υ) is an underchain type. Transport carrier (6) Stock carrier in VC (6
a) into the bottom of the terminal end (6b) of the feed chain (double glue 6 part (21c) and the stock base conveyor (6a), regardless of the safety 9j-friend of the base conveyor (6a). )
The terminal end (6b) of the lamp is shaped like a ramp in the front-rear force direction.

That is, while having the advantage that the reaped culm can be immediately and forcibly conveyed by the feed chain of the under chain, the starting end (21c) of this feed chain υ is connected to the stock conveyor. The terminal part of (6a) (
6,1+X, regardless of the change in posture when the pre-processing section (8) goes up and down, they are always inserted into each other in the front and back direction, so the handing over of the harvested stems and culms is smooth without causing any disturbance in the posture. I was able to go there.

In particular, by extending the starting end of the feed chain toward the front end of the g1j location tsuboto with an M inclination to the front end of the chain, the seventh I@body angle...J location: l! l! The angle is approximately equal to the inclination angle of the stump base conveyor in the reaping husk conveyance device which transfers the reaped husk culm from the n end side of the 6'lS to the start end of the feed chain with a backward upward slope, Is there confusion or stagnation in the transferred grain culms at the transfer point of the series of transfer conveyance routes by both parties? In order to prevent this from occurring, the conveyor path is structured in a series of straight lines on an incline, so that even if the posture of the stock conveyor changes slightly, the transfer is stable for fermentation. Transportation will be carried out by Kano and Yen?il.

In addition, although the starting end of the feed chain that enters under the terminal end of the stock carrier is slanted, the reaping culm that should be inherited from the end of the stock carrier is transferred to the feed chain on the inheritance side. 4i! Since it can be skillfully mounted on the sloping slope of IS Jomon, it is possible to carry out reliable transfers without any mistakes in transfers in a commercial manner.
