SUMMARY OF THE INVENTION Therefore, the above-described actual
In the prior art as described in JP-A-59-101636, the tip of the straw is guided during the transfer of the straw.
Le - a big resistance to rubbing and Le, the attitude of the exhaust straw is disturbed, straw discharge cutter post stroke occurs transport delay - had defects caused troubles in treatment with and straw discharge binding device.

[0005] Further, since the waste straw is transported in a state where the tip portion thereof is lifted up from the bottom plate of the transport passage in the transport process, it is less likely to move while sweeping over the bottom plate.
The waste was easy to accumulate. However, since the straw transport device of the threshing machine is generally in a state in which the straw that came out of the handling room is late for the head, when correcting this, when reaching the outside of the machine, the stem and the head are in the correct posture. There is a need to.

[0006] Also, the aforementioned Japanese Utility Model Application No. 63-113696 is disclosed.
(Japanese Utility Model No. 02-034133)
In the technology described, the base side and the tip side of the straw
For holding and conveying each by chain type holding and conveying device
In addition, immediately below the holding and carrying chain of the straw
Bar-shaped clamping rods are provided directly below and between the clamping transport chains.
You.

Accordingly, in the straw conveying operation, the straw culm
Nipping and transporting two places, the head side and the tip side
However, in general, straw is better on the stock side than on the tip side.
Because the volume is large, the holding chain
Make sure that the driving speed and the driving speed of the
Even if it is set properly, the moving speed of the straw
The speed of movement on the front side is slightly different, and as a result,
At the clamping portion between the stem side and the tip side.
Can cause culm breakage and facilitate the discharge of straw.
There is a disadvantage that disappears.

[0008]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, threshers 1 threshing conveying chain 3 of the transfer terminal end followed by a strain base a clamping while Haiwarakabu root side sandwiching conveyor chain 4 that after end side said to feed transportable the straw discharge overboard with the < br /> provided in a direction away from the conveying direction of the threshing conveying chain 3, then the straw discharge tip side conveyor belt 5 on the tip side of the straw discharge carried by the exhaust straw strain base side挾Ji搬 feed chain 4 end
There provided parallel location such that the front side than the rear end of the Haiwarakabu root side挾Ji搬 feed chain 4, the Haiwarakabu source side sandwiching conveyor chain
A bar opposing the straw conveying base 4 immediately below the straw stock base 4
While the provision of a holding rod in the shape of
Immediately below the holding straw, the holding rod is opposed to the spout tip side conveyor belt 5.
Without providing a clamping guide member as described above,
Nipping and transporting action by the feeding chain 4 and the nipping rod and the spike tip
Straw that is transported by the transport action of the side transport belt 5

Separated from the opposing gripping rod side and on the conveyor belt 5 side
So that it approaches the conveyor belt 5 side of the straw tip
This is a straw conveying device for a threshing machine characterized by being arranged .

As a result, the culm is threshed by the action of the handling cylinder in the threshing machine 1 while being transported by the threshing transport chain 3, and the straw after threshing is threshed and transported to its stock side. inherited from the end of the chain 3 to Haiwarakabu source side sandwiching conveyor chain 4 is conveyed to the outside of the machine.

In other words, the stock side of the straw is held by
The feed chain 4 and a bar-shaped holding rod which is directly below the feed chain 4
The spout side of the straw is guided by a guide rod.

There is no culm and there is less culm, and
Can be.

In addition, a plan for guiding the straw by supporting it from below.
Because the inner rod 6 has a circular cross section, the contact area with the straw is small.
It becomes smaller and less likely to become a resistance for straw transport.
The guide rod 6 avoids the position directly below the straw-tip-side transport belt 5 and

In addition, a plan for guiding the straw by supporting it from below.
The inner rod 6 has a circular cross section to reduce the contact area with the straw.
And it is difficult to resist the transportation of straw.
The inner rod 6 is moved out of the straw

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the configuration will be described. The threshing machine 1 includes a handling room 7, a threshing transport chain 3, a straw transport device 8, and the like.

[0015] The straw conveying device 8 includes a holding straw chain (straight straw).
And a strain base side pinching transport chain) 4, straw discharge conveyor belt (Haiwaraho
And the front-side conveyor belt) 5, is made from the guide rod 6. First, the holding straw chain 4 is composed of a chain supported by a reinforcing frame 9 and a holding rod attached to a bottom plate 10, with the starting end facing the threshing transport chain 3 and the ending end positioned outside the machine. I have. The holding straw chain 4 is provided to be inclined in a plane so as to convey the straw from the handling room 7 while moving it toward the tip.

The straw conveying belt 5 is provided at the leading end of the straw held by the sandwiching straw chain 4 at a predetermined distance from the chain 4. The guide rod 6 is provided between the straw conveying belt 5 and the holding straw chain 4 so as to support the conveying straw from below.

The holding straw chain 4 is configured to be transmitted from the gear box 11. The straw conveying belt 5 is configured to be transmitted from the holding straw chain 4 via a transmission shaft 12. Next, the operation will be described.

First, the threshing operation is started while driving the rotating parts of the machine body. Then, the stem of the grain is clamped by the threshing transport chain 3 and the spike is supplied to the handling room 7 to undergo threshing. In the threshed culm, the root portion of the thresh is transferred from the terminal end portion of the threshing transport chain 3 to the clamping and discharging straw 4 and the leading end portion, which is slightly delayed in transport, has a handling chamber 7.
And reaches the straw conveying belt 5.

In this way, the straw is supplied to the straw conveying device 8.
Is passed on to the plant, the tip and the tip are sandwiched
And the straw conveying belt 5, and an intermediate portion thereof is supported from below by a guide rod 6. Therefore, the straw can be smoothly transported without breaking the tip portion, which is slightly delayed in transport. In addition, the straw can be swept over the bottom plate 10 of the straw passage 2 at the tip thereof, and the waste can be taken out of the machine.

Then, the straw is discharged out of the machine from the terminal end of the straw conveying device 8.
