DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for transporting straw from a threshing machine, and more particularly to a device for effectively utilizing a threshing machine for a combine harvester.

[0002]

2. Description of the Related Art In a conventional straw conveying device of this type of threshing machine, a guide rod for supporting the straw being conveyed is disposed at a tip side of the straw from a straw belt. In addition, 59-101
Japanese Patent Publication No. 636 discloses that a guide rail for supporting and guiding a culm being conveyed from below is provided between a culm conveyance chain and a culm conveyance belt. It is constituted by a shape member, and is constituted continuously in the width direction between the culm transport chain and the culm transport belt.

[0003]

Therefore, in the above-mentioned prior art, the tip of the straw is rubbed with the guide rod during the transfer of the straw, causing a large resistance. There was a defect that disturbs the processing by the straw cutter and the straw bundling device in the subsequent process.

Further, since the waste straw is transported in a state in which the tip portion thereof is lifted upward from the bottom plate of the transport passage during the transport process, the straw 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.

[0005] In addition, the straw to be transported outside the machine must be taken out of the machine while sweeping down the straw debris that has fallen from the straw being transported onto the straw transport path and accumulated. The present invention seeks to solve the above problems.

[0006]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, the holding and discharging chain 4 for transferring the straw to the outside while holding the stock at the transport end of the threshing transport chain 3 facing the threshing machine 1 is tilted so that the terminal end side is away from the threshing transport chain 3. A straw conveying belt 5 is provided side by side on the leading end side of the straw conveyed by the holding straw conveying chain 4 so that its rear end is located forward of the rear end of the holding straw transport chain 4. A guide rod 6 formed of a rod-like member is provided between the conveyor belt 5 and the straw conveyor chain 4 directly below the conveyor belt 5 and in the vicinity thereof. This is a waste conveying device.

[0007]

In this way, 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. From the end of the chain 3, it is taken over by the holding and discharging straw chain 4, and is conveyed to the outside through the discharge passage 2.

At this time, the straw is in the vicinity of the straw transport belt 5 and is supported from below by a rod-shaped guide rod 6, and the stock side and the tip side of the straw are in the above-mentioned state. Since the conveying action is performed by the holding straw chain 4 and the straw conveying belt 5, disturbance in the conveying posture of the straw is reduced.

Further, culm debris and the like fall downward from between the holding and discharging chain 4 and the guide rod 6 or between the between the discharge conveyor belt 5 and the guide rod 6. Furthermore, since the culm being transported has a small contact area with the guide rod 6, the transport resistance is reduced and the culm is transported smoothly.

[0010]

As described above, according to the present invention, the holding straw chain 4 for transferring the straw to the outside while holding the stock at the transport end of the threshing transport chain 3 facing the threshing machine 1 is provided at the end thereof. The side is provided inclining in the direction away from the threshing transport chain 3,
At the leading end of the straw conveyed by the holding straw conveying chain 4, a straw conveying belt 5 is provided side by side so that the rear end of the straw is forward of the rear end of the holding straw conveying chain 4. A guide rod 6 formed of a rod-shaped member is provided between the belt 5 and the straw transport chain 4 so as to be located immediately below the transport belt 5 and in the vicinity thereof, and the straw transport of the threshing machine is provided. Since the device is used as a device, it is possible to smoothly discharge the straw to the outside of the machine by reducing the disturbance of the transporting posture of the straw, and in particular, in the present invention, the intermediate portion of the straw that is firmly held by the straw transport chain 4 has a rod-like shape. Since it is supported by being lifted from the lower side by the guide rod 6, the tip side of the straw is in a thin state in which layers are dispersed on the front and back on average, and for example, threshing work such as performing a cutting process using a cutter in a favorable manner. Can improve efficiency. That.

[0011] Further, since culm debris and the like fall downward from between the clamping and discharging straw chain 4 and the guide rod 6 or between the discharge and transport belt 5 and the guide rod 6, the waste of straw is reduced. And the like can be prevented from being clogged. Furthermore, since the culm during transportation has a small contact area with the guide rod 6, the transportation resistance is reduced and the culm is smoothly transported.

[0012]

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

[0013] The straw discharge device 8 includes a holding waste chain 4 and
It comprises a straw conveying belt 5 and a 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 start end facing the threshing transport chain 3 and the end 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 seeds of the cereals are pinched by the threshing transport chain 3 and the ears are 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.
When it is passed on, the root of the stock and the tip end
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 conveyed without breaking the tip portion, which is slightly delayed in conveyance. Moreover, 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.
