Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvesting machine for combine harvesters, binders and the like, and belongs to the technical field of agricultural machinery.

[0002]

2. Description of the Related Art Conventionally, a raising device for raising a grain culm before cutting has been firmly fixed to the machine side and cannot be easily removed.

[0003]

When grain culms or weeds are caught around a scraping device such as a star wheel that scrapes the grain stalks after cutting back, the front raising device becomes an obstacle. Difficult to remove wrapped culms and weeds.

It is an object of the present invention to easily attach and detach the raising device and to easily eliminate troubles caused by clogging of grain at the scraping portion. The present invention has taken the following technical means in order to achieve the above object.

[0005]

[Means for Solving the Problems] That is, in order to solve the above problems, the invention described in claim 1 is a raising device for causing a grain stalk to be planted in a field by causing it to act from the plant side to the tip side. It is characterized in that it is detachably attached to the mowing frame of the mowing section.

[0006] When a grain culm or weed is wound around the scraping device for scraping the harvested grain culm backward and clogging occurs, the raising device is removed to open the front side of the scraping device largely. The invention as set forth in claim 2 is a raising device for causing a grain stalk to be planted in a field by causing it to act from the plant base side to the tip side, and engaging one side with respect to the cutting frame of the cutting unit. It is characterized in that the other side is attached by the fastening means by the fastening means.

When the raising device is to be removed, one side is a locking means as a fixing means for the cutting frame, so that it can be easily removed only by releasing the fastening means on the other side.

[0008]

According to the first aspect of the present invention, since the raising device is detachably attached, it becomes a hindrance when a jam occurs due to the winding of the grain stem or the like in the scraping portion. By completely removing the entire front raising device, the front side is largely opened, and the jammed grain culms and the like can be easily removed.

According to the second aspect of the present invention, one side of the raising device is fixed by locking means such as hooking, and the other side is fixed by tightening means such as knob bolts. In addition to the effect of the invention described in Item 1, it is possible to attach and detach the raising device extremely easily and easily.
