DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stem / pull raising device equipped on a combine or a binder.

[0002]

2. Description of the Related Art In general, in such a stem-pull raising apparatus, in order to prevent dust such as straw chips from being entangled in the endless rotating chain, the endless rotating chain is attached to a front case and a rear case. It is housed in a middle case consisting of
The front case is configured to be removable during maintenance such as inspection of the endless rotating chain and the raising claw, or lubrication.

[0003]

However, even when the entire chain is covered with the case as described above, the raising claw often scratches the waste chips and the like into the case. On the contrary, the waste chips accumulate in the case. There was a problem. At the time of maintenance, by removing the front case, maintenance work from the front side can be easily performed, but the rear side is covered with the rear case, and especially, the maintenance work on the rear side is difficult to perform. SUMMARY OF THE INVENTION An object of the present invention is to provide a device for raising stems and stems which is excellent in maintainability while eliminating clogging of dust such as straw chips.

[0004]

In order to achieve the above object, a first feature of the present invention is that an endless rotating chain having a plurality of raising claws on a raising frame is rotatable vertically. On the raising path side of the endless rotating chain, only the raising path side
So that the guide can be supported while maintaining the upright posture of the nail.
Also, on the return path side of the endless rotating chain, the guide portion on the return path side of the endless rotating chain is notched.
Then, the front and back surfaces of the rotating surface of the endless rotating chain are formed in an exposed state, and a decorative cover that covers the entire winding path of the endless rotating chain is fixed to the front surface of the raising frame via fixing means. The point is that it is detachably attached. A characteristic configuration of the second invention is that an operating tool of the fixing means is provided on a front surface of the decorative cover. The feature configuration of the third invention is characterized in that the fixing means includes a hook-type engaging portion that prevents the decorative cover from moving back and forth and from side to side by engaging the raising frame from above and below. A pluggable engaging portion for preventing the vertical and horizontal movement of the decorative cover by engaging the raising frame from the front is disposed above and below the decorative cover, and a single operating tool is used. And a fastening portion for fastening the decorative cover to the raising frame.

[0005]

According to the first aspect, the endless rotating chain is
It is raised only on the side of the raised path and is supported only by the frame, and the other parts are completely exposed, so there is no place where dust such as waste chips accumulate,
Since there is no cover or the like on the rear side, the work can be extremely easily performed not only from the front side but also from the rear side by removing the front decorative cover during maintenance.

According to the second aspect of the present invention, since the operation tool for attaching and detaching the decorative cover is provided on the front surface of the decorative cover, it can be easily attached and detached from the front.

According to the third aspect of the present invention, in order to raise and fix the decorative cover to the frame, the decorative cover is simply raised by a single operating tool and tightened to the frame. In addition, since the positioning is fixed by the plug-in type engaging portion, the attachment / detachment of the cover can be performed more easily and quickly.

[0008]

As a result, the clogging of dust such as waste chips can be eliminated, and the maintenance work can be easily performed not only from the front but also from the back. In addition, the handling when attaching and detaching the decorative cover is facilitated, and the work time required for maintenance including the attaching and detaching of the decorative cover can be reduced.
