Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cutting device for shredding waste culms transported in a posture perpendicular to the transport direction, and a binding device for binding and releasing the waste culms. This relates to culm processing devices arranged in parallel in a direction orthogonal to the direction.

In this type of waste culm processing equipment, both ends of the waste culm enter the cutting device and the bundling device almost simultaneously, so when performing cutting work, both the cutting device and the bundling device are operated. The culm is scraped by the cutting rod of the cutting device and the pucker of the bundling device, but the stock base is accumulated between the pucker of the bundling device and the T projection, and the T projection is activated to remove the needle and knotter bill. etc. is activated,
That is, the culm is bent by the scraping rod and drawn into the cutting device before pressure is applied to the T projection.

In the conventional tying device, as shown in Fig. 6, the tying string suspended between the knotter bill and the twenty-one dollar at the retraction limit position is configured to pass through the front position of the T projection. When the culm was pulled in by the raking rod, there was a risk that the binding cord would get caught on the culm and be pulled into the cutting device.

According to the present invention, by providing the binding string suspended linearly between the knotter bill and the needle at the retraction limit position so as to pass through a position behind the T protrusion, the binding string is caught on the culm of the cutting device. The purpose is to prevent the operator from being drawn into the process and allow for smooth work.
