Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cutting husk lifting device, which can be used in a combine harvester, a reaping machine, or the like. In the case of a reaping culm pulling device such as a combine harvester, in order to make it easier to perform a series of culm processing from culm lifting to harvesting, collecting, and transporting, the upper end side is set higher than this on the left and right sides of the low middle pulling device. By providing a pair of external lifting devices inclined in a V-shape from the front in order to approach the
There is a form in which the tip of the grain culm is collected in the narrowest possible width and is harvested and transferred from the hoist. In this form, the lug of the middle hoisting device is located at the top of the hoisting part of the culm, and the lug is pulled into the hoisting case. If it is too early, it tends to provide resistance to the pulling action of the culm, and if it is too slow, it tends to disturb the tip of the spike that has been pulled and assembled.

The present invention is intended to eliminate such defects, and for this purpose, the following technical measures have been taken. That is, left and right direction -
