Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combine harvester equipped with a pulling device and a reaping device, which are attached to the front part of the combine harvester so as to pull up three-row planted stem culms rearward and upward for reaping. In conventional mbine, three-row, three-row, four-row, etc. were developed depending on the number of rows to be cut, but as the number of rows was increased, the cost of cutting increased significantly. .

The reason for this is the increase in the size of the machine and the size of the threshing equipment, but when it comes to three-row or four-row cutting, the culm is pulled up (41) and the removed husks are moved larger toward the starting part of the vertical conveyor to send them to the threshing foot chain. This is largely due to the fact that the structure requires horizontal transportation.

On the other hand, if we review its usage as a combine harvester, we find that the yield per unit area varies considerably depending on the region.Therefore, when working at the same reaping speed, the throughput of a combine harvester per unit time tends to vary considerably depending on the region.

Under such circumstances, the amount of processing per unit time (volume)
Users in rural areas with few harvests often increase the working speed and perform high-speed work because their combine harvesters have sufficient processing capacity for three-row cutting. It is better to cut three rows at the same time in order to reduce time loss when turning in the field, so attempts have been made to raise and reap three rows of planted stems with a three-row harvester.

However, using a combine harvester that is originally designed for three-row reaping, spreading only the cutting width to perform three-row reaping work does not stabilize the lifting posture of the stem culm, and there are still disadvantages such as omissions in lifting. In the end, stable work could only be achieved by using a combine harvester with the functions of a full-fledged three-row combine harvester, which would be expensive.

The present invention is a so-called full-fledged three-row reaping combine that is equipped with a lateral conveying device for horizontally conveying the tip of a stalk culm that has been pulled up by effectively utilizing the arrangement of a pulling device provided in the combine. Our aim is to provide a combine harvester using three rows, which is equipped with a pulling device that can be used as a broom, even if the threshing section and conveyance section have a mechanism that has the simple function of a conventional three row harvester. It has a purpose.

The characteristic structure of the combine harvester according to the present invention is that the pulling action path of the pulling device located on the most cut side so as to pull up the stem culm on the cut side opposite to the threshing section feed chain position is The path is configured to be an inclined path from the mowing side to the uncut side, and the pulling action path of the central pulling device is arranged in the middle of the pulling action path of the pulling device on the already cut side. The structure is located at the point where the two meet, and this configuration provides the following effects.

That is, the pulling action path of the mown side pulling device is inclined, and the pulling action path of the cutting side pulling device and the pulling action path of the uncut side pulling device are made so that the terminal side thereof is Since the pulling devices are arranged so that they are close to each other, the tips of the pulled stem culms are in a state of being close to each other, and therefore a special horizontal conveying device is required to bring the tips of the stems and culms together. This has the advantage that the structure of the stem culm conveying system can be significantly simplified and costs can be significantly reduced.

In addition, the stem culm pulled up by the central pulling device has a pulling action path whose end is inclined toward the threshing section feed chain side. Since the culm is merged in the middle of the working path, the culm that merges with the central pulling device and the pulling device on the cut side,
In the raising process, both of them are transferred toward the threshing section feed chain side, and after that, the force of the stem culm on the uncut side, which is smaller in amount than the merged stem culm, is combined, and as a result,
This is also advantageous in that the entire stem culm tip is tilted toward the threshing section feed chain side, where a large amount of merged stem culms are transferred, making it easy to carry out subsequent rearward conveyance smoothly. .

Embodiments of the present invention will be described below with reference to the drawings.

Figures 1 and 2 show the entire combine d, which is used for mowing by pulling three rows of planted stalks at the front of the machine.

Three pulling devices 2.2', 21/, whose starting end intervals are set in contrast to the rows of the planted stem culms, are installed side by side in the left and right direction of the machine, and a Karisaka somachi After being pulled up and cut, the stem culms are transferred to a vertical conveyor.
It was moved backwards and upwards, but then it was carried away.

At the end of the feeding path, the grain is changed to a horizontally lying position and fed into the threshing device B, and is transported rearward by the threshing part finido chain 11 for threshing processing.

Among the pulling devices 2.2', 2//, the pulling device 2 is located on the cut side opposite to the side where the threshing section feed chain 11 is located, and the pulling device 2 is located in the center. 2
'' means, as shown in Fig. 3, 'a plurality of pulling claws 4, 4' facing each other so as to pull up two adjacent stem culms backward and upward. It is equipped with a pulling chain 6.6' which is attached and is hung so as to be rotatable through three sprocket wheels 5. In addition, the pulling devices 2 located on the already cut side are disposed facing each other in a state where they are displaced rearward and facing each other.

Of the picture raising devices 2, 2', one of the sprocket wheels 5 of the pulling device 2, which is located on the outside side of the machine body which has been cut, is connected to the outside side of the already cut side near the ground. In this position, the other sprocket wheels 5, 5 are respectively disposed at the rear upper lateral inner side position and the rear upper lateral outer side position on the mown side, so that the stem culm pulling action path 3 is close to the mown side. The three sprocket wheels 5' of the other pulling device 2'
... at the lateral medial position near the ground, the other at the rear upper lateral lateral side closer to the already cut side, and the other at the rear upper lateral medial position, respectively. Central? Raising device 2
'The pulling action path 3' of the front mulberry is configured in an inclined position so as to intersect with the pulling action path 3 of the former pulling device 2 at a midway point thereof, and the pulling action path 3' of the former pulling device 2 on the already cut side The action surface 3a of the lifting action path 30 (rotating plane of the lifting claw 4) is configured to be an inclined surface facing inward from the outside of the fuselage, so that the action surface 3a of the lifting claw 4... The path intersection A where the stem culm is connected to the former cutting side pulling device 2 and pulling both stem culms diagonally inward to merge is defined as the lifting action path of the cutting side pulling device 2. 3, and the terminal end of the lifting action path 3 is configured to merge into the pulling path 1.

Then, another pulling device 2〃 is installed in the machine body or at a position closer to the uncut side to pull up the planted stem culm closest to the uncut side. The lifting action path 3 is a pulling mechanism for the already-made shaft u! Since the lifting action paths 3 of 2 are sloped paths, the image lifting action paths 3, 3 become closer to each other toward the end of the lifting operation. .
