設しである排ワラ処理装置に関する。[Detailed description of the invention] The present invention has a disk-type ejector that cuts the ejected straw at multiple points in the culm length direction in the lower part near the end of the ejected straw conveying device that conveys the ejected straw in a horizontally suspended position. The present invention relates to a waste straw processing apparatus which is provided with a straw cutter and a waste straw convergence and discharge device arranged behind the waste straw cutter.

一般に、脱穀処理された排ワラは、穂先遅れ状態で脱穀

る。If this is fed directly to the disc-shaped cutter at the end of the conveyor by passing it through the carrier, the waste straw will be fed in an oblique position with respect to the cutter shaft, and the tips of the straw will escape, causing the straw to be removed. There is a drawback that the shredding ability decreases.

本考案は、上記欠点を解消すると共に、カッターと排ワ

かかる構成から次の作用効果を奏する。The characteristic configuration of the waste straw processing apparatus of the present invention is that the waste straw conveying apparatus is of an underchain type in which a clamping rail is located at the top and a conveyance chain is placed at the bottom, and the end of the conveyance chain is connected to the It is located behind the cutting point where both rotations of the disc-type waste straw cutter overlap in the waste straw transfer direction, and at the end of this waste straw conveying device,
The conveyor chain is formed in a shape that roughly follows the shape of the bending point at the terminal end, and is located at a position corresponding to the bending point at the terminal end, and has a straw discharging member for the return path toward the cutting point of the disk-shaped straw discharging cutter. A guide tool configured to be freely switchable between a first position in which the waste straw is guided and supplied, and a second position in which the waste straw is dropped and released directly from the terminal end of the conveying chain away from the terminal bending point to the waste straw collection and discharge device side. A cut point is provided at a position in the middle of the return path that goes down to the lower side of the conveying chain, and at a position downstream from the cutting point of the straw removal cutter in the direction of force for transferring the waste straw. a damming posture facing the cutting point on the tip side so as to prevent the waste straw that has reached the cutting point from passing through the cutting point;
A catch that can be freely switched between a horizontal position and a horizontal position substantially along the feed path toward the terminal end on the upper side of the conveyor chain is provided; When the receiving tool is in the damming position, and when the guide tool is in the second attitude, the receiving tool is in a horizontal position.
This configuration provides the following effects.

るに至った。In other words, the conveying device is constructed in an underchain type, and its terminal end is positioned behind the cutting point of the cutter, so that the conveyed waste straw is made a U-turn at the terminal end of the device and is supplied to the cutter. When the conveyed waste straw whose ears are bent in an arched shape due to the threshing action passes through the bending path at the end of the conveying device, the ears are rotated by the screws with the clamping point on the stock base side as the center of oscillation. As a result, the tip lag is restored when passing through the bent path portion, and the waste straw is supplied approximately parallel to the cutter axis, resulting in good shredding. Ta.

ができるに至った。Furthermore, since a catch is provided on the side of the end of the conveying device to prevent the conveyed waste straw from hanging down, the hanging conveyed waste straw can be conveyed to the soot 1-z without being dragged by other devices. In addition, the posture of this receiving tool is changed and it is used as a stopper to prevent the waste straw from being sent further down the conveyance side than the cutting point of the cutter, so it is possible to cut the waste straw. Moreover, even if the waste straw processed by the cutter accidentally scatters, it can be caught without escaping, and it can be reliably fed into the cutter and shredded.
