Abstract

An agricultural baler. The agricultural bailer includes a baling chamber, a first plunger, a second surface opposing the first plunger, and a track assembly. The baling chamber includes a first wall and a second wall. Each of the first wall and the second wall includes a slot extending along a length of the baling chamber. The first plunger is moveable within the baling chamber and is configured to compress a compressible material into a bale. The second surface is configured to support the compressible material within the baling chamber. Each of the first plunger and the second surface includes a slot aligned with the slots of the first wall and the second wall. The track assembly includes a gated channel and is disposed within the slots of the first wall, the second wall, the first plunger, and the second surface such that the track assembly substantially surrounds the baling chamber.

First claim

What is claimed is:

1. An agricultural baler comprising:
a baling chamber configured to receive a compressible material, the baling chamber comprising a first wall and a second wall, the first wall opposing the second wall, each of the first wall and the second wall comprising a slot extending along a length of the baling chamber;
a first plunger moveable within the baling chamber, the first plunger configured to compress the compressible material into a bale;
a second plunger opposing the first plunger, the second plunger comprising a second surface opposing the first plunger, the second plunger coupled to an actuator that enables the second plunger to move in a second direction while a force applied by the compressible material against the second plunger exceeds a threshold value, the second surface configured to support the compressible material within the baling chamber, each of the first plunger and the second surface comprising a slot aligned with the slots of the first wall and the second wall; and
a track assembly comprising a gated channel, the track assembly disposed within the slots of the first wall, the second wall, the first plunger, and the second surface such that the track assembly surrounds the baling chamber,
wherein the agricultural baler is disposed on a movable agricultural implement.

2. The agricultural baler of claim 1 , further comprising a mechanical stop configured to limit movement of the second plunger in the second direction to control a size of the bale.

3. The agricultural baler of claim 2 , further comprising a sensor configured to detect the presence of the second plunger against the mechanical stop, wherein the first plunger is deactivated when the sensor detects the presence of the second plunger against the mechanical stop.

4. The agricultural baler of claim 1 , further comprising a strap feeding assembly configured to propel a strap through the gated channel of the track assembly.

5. The agricultural baler of claim 4 , further comprising a sealing assembly configured to receive the strap and to seal an end of the strap to a portion of the strap to form the strap into a loop surrounding the bale within the baling chamber.

6. The agricultural baler of claim 1 , wherein the agricultural implement is a self-propelled vehicle.
