Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting pretreatment device for an all-cule throw-in type combine, which is configured so that a cutting grain culm is laterally fed by an auger and then conveyed to a threshing device by a feed conveyor.

[0002]

2. Description of the Related Art In all culm-type combine harvesters, rice
Harvest not only wheat but also beans such as soybeans and other minor grains. In this case, when rice / wheat or minor grains with relatively small grains and less soil contamination are targeted for harvesting, the transport bottom plate of the feed conveyor is made into a blind plate shape in order to reduce the recovery loss in the pre-mowing treatment device. It is desirable that the bottom plate of the transfer device be set so that the soil contained in the harvested product can be dropped and discharged during transportation when beans such as relatively large grains and a large amount of soil mixed in the harvested product are targeted for harvesting. It is desirable to make it porous. Therefore, conventionally, a blind plate-shaped transport bottom plate and a porous transport bottom plate are prepared, and the transport bottom plate is exchanged according to the harvesting object to switch between the blind plate shape and the porous plate.

[0003]

However, according to the above-mentioned conventional means, it is troublesome to replace the carrying bottom plate, and at the same time,
The storage of the unused transport bottom plate was troublesome. In addition, when the bottom plate for transportation is made porous, the size of the holes is constant, so depending on the harvest target, it may flow out from the soil discharge holes to the grains, increasing recovery loss, or conversely, insufficient soil discharge. As a result, the amount of soil brought into the threshing device increased.

The object of the present invention is to enable the transfer bottom plate of the feed conveyor provided in the cutting pretreatment device to be switched between the blind plate shape and the porous shape according to the object to be harvested, and the switching can be easily executed. The point is that the optimum hole size can be selected according to the harvest target so that the recovery loss and the soil carry-in can be reduced.

[0005]

The invention according to claim 1 is
After transversely feeding the cut culm with an auger, in the pre-cutting device of the all culm throw-in type combine configured to be conveyed to the threshing device by the feed conveyor, the conveyance bottom plate of the feed conveyor is a top and bottom stack of two sheets. In addition to being formed of a perforated plate, one of the perforated plates can be slidably and fixedly operated with respect to the other perforated plate along its overlapping surface so that the transport bottom plate can be switched between a blind plate type and a porous type. It is characterized by being present.

According to a second aspect of the present invention, in the pre-cutting treatment device for all-cullet throw-in type combine according to the first aspect, the conveying bottom plate of the auger is formed of two perforated plates that are vertically stacked, and Is characterized in that the perforated plate can be slidably and fixedly operated with respect to the other perforated plate along the overlapping surface thereof, and the conveying bottom plate can be switched between a blind plate type and a perforated plate.

[0007]

According to the structure of claim 1, by sliding one of the two vertically stacked perforated plates with respect to the other, the transport bottom plate of the feed conveyor is made into a blind plate shape depending on the object to be harvested. It can be switched to a porous structure, reducing the collection loss and soil carry-in regardless of the harvest target. In particular, it is possible to easily switch between the blind plate type and the porous type by a simple operation of sliding one of the perforated plates, and the troublesomeness associated with the storage of unused parts as in the prior art described above is eliminated. There is no. Furthermore, by changing the relative fixing position of the perforated plate, the lap margin of one hole and the other hole can be adjusted appropriately, and the size of the holes on the bottom plate for transportation can be selected to the optimum state according to the harvest target. The function to reduce the collection loss and the carry-in soil can be further improved regardless of the harvest target.

According to the second aspect of the present invention, the bottom plate of the feed conveyor can be switched between a blind plate type and a porous plate type, which can reduce recovery loss and soil carry-in regardless of the object of harvesting, and reduce Even in the bottom plate for transportation, by sliding one of the two vertically stacked perforated plates with respect to the other, it is possible to switch between blind plate type and porous type according to the harvest target, regardless of the harvest target. Without collection loss and dirt brought in.

[0009]

According to the invention of claim 1, it is possible to switch the conveying bottom plate of the feed conveyor in the pre-mowing device to a blind plate type or a porous plate according to the harvesting target, and the switching is simple and the harvesting target is selected. The optimum hole size can be selected according to the requirements, and it is excellent in the function of reducing the recovery loss and soil carry-in in the mowing pretreatment device and the ease of use.

According to the invention of claim 2, not only the transfer bottom plate of the feed conveyor but also the transfer bottom plate of the auger can be switched between the blind plate shape and the porous shape according to the harvesting object, and the switching is simple and the harvesting is easy. The optimum hole size can be selected according to the target, and it is even more excellent in the function of reducing the recovery loss and the amount of soil carried in the pre-mowing treatment device and the ease of use.
