DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a harvester for cutting soybeans, for example.

"Prior Art" Conventionally, JP-B-62-144435 or JP-B-2-63622
As shown in Japanese Patent Publication, a plurality of projections are provided on upper and lower two-stage transport chains for sandwiching and transporting crops, and a cutting blade for cutting the roots of the crops is provided on the feed start end side of the transport chain to cut soybeans. There is a technology to do.

[Problems to be Solved by the Invention] In the above-described conventional technology, one set of crops is collected by one set of transfer chains. Therefore, two sets of transfer chains are required to simultaneously cut two sets of crops. Yes, there is a problem that the transportation route for crops tends to be complicated. In addition, since the running wheels are arranged left and right with respect to the feed start end of the transport chain, the running wheels move between the crop cutting traces (between the crop lines), and the uncut There is a problem that it is easy for the running wheels to come into contact with the crop and to shed it.

[Means for Solving the Problems] Therefore, according to the present invention, a plurality of projections are provided on upper and lower two-stage transport chains for sandwiching and transporting crops, and a cutting blade for cutting a crop plant is provided with a feed start end of the transport chain. In the harvester provided on the side, a Y-shaped transport path for two-row cutting is formed by the transport chain, and the left-right spacing on the bifurcated feed start end side of the transport chain is set to the pair of left and right traveling crawlers mounted on the machine. It is formed to have a width substantially equal to the traveling installation width, a rolling wheel is provided for supporting the front portion of the transport chain, and the rolling wheel is attached to a lower side at a substantially horizontal center of a bifurcated feed start end portion of the transport chain. And

[Action] Therefore, since the Y-shaped carrying path for two-row cutting is formed by the carrying chain, crops for two articles can be cut almost simultaneously and carried to the same place, improving work efficiency and simplifying the carrying chain structure. In addition to the fact that the two-pronged feed start end of the transport chain is placed in front of the left and right traveling crawlers, the traveling crawler moves along the cut mark of the crop, causing the traveling crawler to come into contact with the uncut crop and cause grain loss. And can easily improve the collection efficiency of crops such as soybeans that are easy to shatter,
In addition, since the rolling wheels that support the feeding start end of the transport chain move between the rows of the crop, the rolling wheels can be easily placed in a hard field scene away from the crop, and the transport chains can be stably supported by the rolling wheels. It is possible to easily reduce a change in the ground height of the chain feed start end portion, and to keep the cutting height of the crop substantially constant to easily prevent uncut areas from occurring.
