Abstract

A stripper device, for reducing adhesions on a movable part of a baler including a pressing apparatus interacting with a bale, has a scraper bar carrier with a scraping bar, wherein the scraping bar carrier can be movably connected to the baler and has a first position, in which the scraping bar is operatively abutted against the pressing apparatus, and a second position, in which the scraping bar is withdrawn from the pressing apparatus, wherein the scraping bar assumes the second position cyclically.

First claim

The invention claimed is:

1. A round baler comprising:
a frame;
a baling chamber;
a pressing apparatus for forming a bale in the baling chamber;
a tensioning lever pivotably mounted to the frame and interconnecting the frame and the pressing apparatus for maintaining a tension in the pressing apparatus;
a tensioning arm coupled to the pressing apparatus and rotatably mounted to the frame for rotational movement relative to the frame in response to movement of the pressing apparatus by the tensioning lever;
a stripper device including:
a tensioning arm lever attached to the tensioning arm and rotatable with the tensioning arm;
a bar carrier pivotably connected to and moveable relative to the frame between a first position and a second position;
a scraping bar attached to and moveable with the bar carrier between the first position and the second position;
wherein the scraping bar is abutted against the pressing apparatus when disposed in the first position for removing adhesions from the pressing apparatus;
wherein the scraping bar is withdrawn from the pressing apparatus when disposed in the second position;
an articulated lever attached to and rotatable with the bar carrier; and
a connecting rod interconnecting the articulated lever and the tensioning arm lever, such that rotational movement of the tensioning arm moves the connecting rod, which in turn rotates the articulated lever to move the bar carrier between the first position and the second position.

2. The round baler of claim 1 , wherein the pressing apparatus is constructed in the form of an endless pressing belt.

3. The round baler of claim 1 , wherein the connecting rod includes a spring.

4. The round baler of claim 1 , wherein at least a portion of the scraping bar is flexible and is in the form of a rubber strip or lip.

5. The round baler of claim 1 , wherein the tensioning lever is provided to maintain a specifiable tension of the pressing apparatus during at least one of opening of the baling chamber and ejection of the bale.

6. The round baler of claim 1 , wherein the stripper device is arranged in an area of the baling chamber facing a drawbar of the round baler, and cooperates with an outer side of the pressing apparatus.
