  However, in large reaping parts such as for 5 or 6 reaping, the amount of cereals to be fed to the feed chain increases, and the space required for raising and lowering the reaping part is between the terminal conveying member of the reaping part and the feed chain. By ensuring, there is a problem that the cereal inheritance posture is disturbed at the start end of the feed chain, and the cereal is easily dropped.

Therefore, in the present invention, in the combine provided with the transfer conveying member that transfers the cereals from the terminal conveying member of the cutting unit to the feed chain, the rod-shaped transfer guide front end is pivotally supported by the frame of the cutting unit, while the cutting unit The lifting / lowering fulcrum pipe, which is the lifting / lowering fulcrum, is provided with the above-described transfer conveyance member so that the relative position of the transfer / conveyance member and the feed chain is always kept substantially constant. And the other end side of the rod-shaped receiving guide is extended to the front of the feed chain via the front portion of the transfer conveying member. The conveying space from the terminal conveying member to the feed chain is gradually expanded to smoothly convey and move the cereal. There is provided a combine being characterized in that configured to prevent with each other come 稈姿 bias is disturbed.

In the present invention, the front end of the rod-shaped transfer guide is pivotally supported on the reed frame of the cutting part, while the transfer conveying member is provided on the lifting support pipe that is the lifting support point of the cutting part, and the relative position of the transfer conveying member and the feed chain The rear end of the rod-shaped transfer guide is brought into contact with the upper transfer portion of the transfer conveying member from above , and one end of the rod-shaped receiving guide is fixed to the lower surface of the terminal transfer member. The other end side of the bar-shaped receiving guide is extended to the front part of the feed chain through the front part of the conveying member, and the conveying space from the terminal conveying member to the feed chain is gradually expanded to smoothly convey and move the cereal. The above-described transfer conveying member and feed chain are configured to attract the same culm and prevent the cocoon posture from being disturbed.

Accordingly, it is possible to stably carry the cereal while keeping the relative position between the transfer carrying member and the feed chain substantially constant. In addition, the bar-shaped receiving guide can regulate the downward bending of the cereal stock that is conveyed from the terminal conveying member to the feed chain via the inherited conveying member, and can smoothly convey and move the cereal. In addition, it is possible to prevent the posture of the cocoon from being disturbed by attracting the same corn cake by the transfer conveying member and the feed chain.
As a result, the inheritance performance of corn straw can be improved, and even in a large structure in which the amount of corn straw increases, it is possible to prevent the corn straw from dropping off or the posture of the straw from being disturbed at the front part (starting end) of the feed chain. .
