Variable speed round bale chamber control with accumulator sensor
A sensor detects a characteristic of accumulated crop material and a controller manipulates the speed of a baling chamber in response thereto. The speed of a baling chamber of a variable speed baler is manipulated in response to a characteristic of an accumulated crop material. For example, the height of accumulated crop material in an accumulation area may be detected and the speed of the baling chamber manipulated in response thereto. The rate of growth of the bale may also be determined and used in manipulating the speed of the baling chamber.
1. A method comprising:
detecting height of an accumulation of crop material to be fed to a round baler with a sensor;
manipulating the speed of bale forming belts in a baling chamber of the round baler using a controller to control at least one powered drive roll in response to the detected height; and
determining whether the detected height is greater than a predetermined height, and if the detected height is greater than the predetermined height, running the bale forming belts at full speed.
2. A method comprising:
detecting height of an accumulation of crop material to be fed to a round baler with a sensor;
manipulating the speed of bale forming belts in a baling chamber of the round baler using a controller to control at least one powered drive roll in response to the detected height; and
determining whether the detected height is greater than a predetermined height, and if the detected height is not greater than the predetermined height, determining a bale growth rate value.
3. A method comprising:
detecting height of an accumulation of crop material to be fed to a round baler with a sensor;
manipulating the speed of bale forming belts in a baling chamber of the round baler using a controller to control at least one powered drive roll in response to the detected height;
determining whether the detected height is greater than a predetermined height;
determining a bale growth rate value; and
if the bale growth rate is greater than zero running the bale forming belts at a user-provided desired speed.
4. A method comprising:
detecting height of an accumulation of crop material to be fed to a round baler with a sensor;
manipulating the speed of bale forming belts in a baling chamber of the round baler using a controller to control at least one powered drive roll in response to the detected height;
determining whether the detected height is greater than a predetermined height;
determining a bale growth rate value; and
if the bale growth rate is less than zero, then determining whether the height of the accumulated crop material is greater than a second comparison value, and if the height of the accumulated crop material is less than the second comparison value, then stopping the bale forming belts.
