Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cutting device for cutting the culm and a dam for bundling the culm at the bottom of the culm passageway through which the husks are threshed, pounded, and discharged by a threshing device such as a combine harvester. The present invention relates to a culm processing device in which a part of the binding device is arranged side by side in the longitudinal direction of the culm, and the cutting operation and the binding operation of the culm are performed by switching.

Conventionally, the waste culms that have been threshed by the threshing device of a combine harvester are generally cut by a cutting device installed at the rear of the combine and released onto the ground, but the waste culms are not cut but bundled and released. When necessary, a binding device is further attached to the rear of the cutting device, or the cutting device is removed and a binding device is installed in its place to perform the culm binding operation.

In the former case, these methods have a complicated structure, and the mechanism for switching and transporting them is complicated.

In the latter case, it was not easy to replace and install the cutting device and the binding device.

In view of the above problems, various configurations have been developed, such as a configuration in which the cutting device and the binding device are arranged vertically or horizontally, and a configuration in which the cutting device and the binding device are integrated. However, in the conventional devices, the transmission mechanism and the like are complicated, and the overall structure is relatively large, which is not satisfactory.

The needle 67 rotates to wrap the binding string around the culm and feed it into the string *) Lif-71.

Next, the knotter bill part 69 ties and cuts the binding cord, and at the same time, the T projection 51 swings and retreats, and the bundled discharged culm bundle is pushed onto the discharge chain 77 by the discharge rod 75 and discharged to the ground. It is.

As can be understood from the above description of the embodiments, the gist of the present invention is as stated in the claims. are bundled together and released as they are, but when cutting with a cutter, a feed roll feeds them to the lower rotating blade and cuts them, and the power for these is rotationally linked to the input shaft from the machine body side. However, since this input shaft is disposed at the lowest position with respect to the interlocking shaft or rotating shaft located below the discharge culm passage, and does not protrude outward for a long time, this interlocking is difficult. easy to understand,
By arranging and interlocking the rotary blade of the cutter on this human power axis, and thereby configuring the upper feed roll and binding device portion to rotate and interlock, the interlocking configuration of the portion located below the culm discharge passage can be achieved. can be simplified, and the entire device can be configured to be smaller in both vertical and longitudinal directions.

It can be made lighter and smaller and easier to handle.
