Abstract
A baler including a frame, and a compression system coupled to the frame, where the compression system at least partially defines a compression chamber. The baler also includes a feed pan at least partially defining a pre-compression chamber in operable communication with the compression chamber, where the feed pan includes an inlet defining an inlet area and an outlet defining an outlet area, and where the outlet of the pre-compression chamber is open to the compression chamber of the compression system. The baler also includes at least one actuator coupled to the feed pan, and a controller in operable communication with the at least one actuator, and where the controller is configured to adjust the inlet area and the outlet area independently.
Claims21
A baler comprising:
- a frame;
- a compression system coupled to the frame, the compression system at least partially defining a compression chamber;
- a feed pan at least partially defining a pre-compression chamber in operable communication with the compression chamber, wherein the feed pan includes an inlet defining an inlet area and an outlet defining an outlet area, and wherein the outlet of the pre-compression chamber is open to the compression chamber of the compression system;
- at least one actuator coupled to the feed pan;
- and
- a controller in operable communication with the at least one actuator, and wherein the controller is configured to adjust the inlet area and the outlet area independently.
A baler for use with a forming bale, the baler comprising:
- a frame;
- a compression system coupled to the frame, the compression system including a compression chamber sized to receive at least a portion of the forming bale therein, and a plunger at least partially positioned within and movable with respect to the compression chamber;
- and
- a controller in operable communication with the compression system, and wherein the controller is configured to calculate the density of crop material at two or more different locations within the bale.
A method of baling with a baler having a compression system defining a compression chamber sized to receive a forming bale therein and a pre-compression chamber open to the compression chamber with an adjustable shape, the method comprising:
- calculating a first density data point indicating a density of crop material at a first location within the forming bale;
- calculating a second density data point indicating a density of crop material at a second location within the forming bale different than the first location;
- compiling the first density data point and the second density data point to produce a vertical profile;
- and
- adjusting the shape of the pre-compression chamber based at least in part on the vertical profile.
