Then, the start end side of the waste root transport device 22a and the waste spear tip transport device 22b is connected to the end side of the feed chain 20 and the pinch 21, so that the threshed waste is transported to the waste processing device 8. It is configured.

  Further, as shown in FIGS. 4 to 7, a threshing cover 23 is provided on the upper portion of the handling chamber 12 so as to be rotatable about an axis in the front-rear direction. The opening / closing end of the threshing cover 23 near the feed chain 20 is provided with a culm transfer port 24 along the feed chain 20, and a clamping table 26 is fixed. The scissors 21,... Are attached so as to face the cereal conveyance unit of the chain 20.

  The clamps 21,... Are pivotally connected to a large number of clamp bodies 21 a,. The pins 21b,... Are supported by rods 21c,... Slidably supported in the vertical direction, and are pressed to the lower feed chain 20 side by springs 21d,. It is the structure which pinches and conveys a grain candy between.

  Moreover, as shown in FIG.4 and FIG.6, the upper side grain conveying part of the middle part of the feed chain 20 is comprised in back up inclination shape by side view, and the terminal side is comprised in back inclination form. Further, the clamps 21,... Are opposed to the rearwardly inclined portion of the feed chain 20 so as to face the end side of the rearwardly inclined portion of the feed chain 20 and above the rearwardly inclined portion. Then, the starting end side of the waste root transport chain 22a and the waste tip transport chain 22b of the waste transporting device 22 is faced, these are extended in parallel and inclined inwardly toward the inner end, and the waste is taken over and handed over. It is configured to be conveyed to the processing device 8.

  Further, in this takeover transport section, an auxiliary gripper 25 that can be adjusted in the transport direction is attached to the final stage side clamp base 26, and the end side part and the rearward downward slope part of the rear upward inclined part of the feed chain 20 Are arranged opposite to each other. And this auxiliary pinch 25 is comprised in the plate body along the conveyance direction and the up-down direction.

  In the conventional apparatus, as shown in FIG. 6 (B), since the auxiliary scissors 25a are made of piano wire, when the terminal side is far from the mounting portion, the pinching force of the waste is weakened, and the threshed grains There was a problem in that the handing over posture of the bag to the waste transporting device 22 was disturbed.

  However, in the said structure, since the auxiliary claw 25 was comprised in the board body of the up-down direction along the conveyance direction, the clamping force in the termination | terminus side is maintained strongly, and although it is an inexpensive structure, threshing finished grains Takeover conveyance performance can be improved.

Next, the waste transporting device 22 will be described with reference to FIGS.
On the end side of the feed chain 20, the start end side of the waste root transport chain 22 a of the waste transport device 22 is faced, and a waste spear tip transport chain 22 b is provided in parallel toward the inside of a predetermined interval.
