DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pretreatment apparatus for a multi-row combine having five or more rows.

[0002]

2. Description of the Related Art In combine harvesters, a plurality of dividers for weeding trichomes are arranged laterally in the lower part in front of the raising device in correspondence with the strips. The left and right widths of the crawler traveling device and the divider are set to be substantially the same width, and the left end divider and the left and right crawler outer end sides are arranged at almost the same position.

[0003]

However, the combine is used for cutting the culm while the traveling body, which is a heavy object, is traveling on a soft field such as a rice field, and the crawler is liable to sink, so during the operation, In many cases, the crawler pushes up foreign substances such as mud, straw, weeds and the like in the field to the side, and drops mud carried by the crawler. Especially,
This tendency is strong in a multi-shed combine with five or more cuts because the weight of the body and the weight of the paddy in the grain tank increase.
For this reason, mud and foreign matter from the field, which have been pushed up or dropped by the crawler, enter the divider (within the cutting width) in the next process. This causes problems such as causing the cutting blade to wear quickly and shortening the life of the cutting blade.

[0004]

SUMMARY OF THE INVENTION A combine pre-treatment device according to the present invention is based on the above-mentioned actual condition, and has a weeding action of erected cereal culm at a lower front portion of a raising device. In a multi-row cutting combine of five or more rows in which a plurality of dividers are arranged in a horizontal direction corresponding to the strips, the rightmost divider in the advancing direction of the machine is moved in front of the sitting operation section by a crawler. It is provided on the virtual extension line of the outer end of the right crawler in the traveling device , and the seating operation unit is provided with
A multi-shed combine pre-processing device, wherein the pre-processing device is provided so as to protrude outward, and the left end divider is provided at least outwardly from the outer end of the left crawler by a distance corresponding to a line.

[0005]

According to the present invention, since the left end divider is provided at least outwardly from the outer end of the left crawler by a distance between the crawlers, the divider is dropped from the crawler during the harvesting operation or is pushed up by the crawler. In this way, it is possible to prevent foreign matter such as mud, straw, weeds, and the like from rising in the field from entering the divider (within the cutting width) in the next process. This prevents mud and contaminants from being brought into the cutting blade and the transporting body, thereby preventing transport jamming due to mud and the like, and greatly improving the durability of the cutting blade.
