Benefits of technology

The patent describes a method for controlling the speed of a power take-off (PTO) in a machine used for making bales. The method automatically determines the optimal speed based on the operating conditions and controls the formation of the bale accordingly. This automation makes the process more efficient and saves time.

Problems solved by technology

A higher number of revolutions of the bale in the bale chamber, however, increases the amount of power needed and, consequently, increases the amount of fuel consumption.
Further, each time the bale rotates, the bale may be damaged by components (e.g., rolls and belts) and crop material may fall out of the baler chamber.

Embodiment Construction

[0021]The number of rotations needed to form a bale of a desired density may be controlled by tractor PTO speed and bale density pressure. Conventional methods and systems for forming bales manually set the PTO speed and bale density pressure prior to the operation of the formation of the bale. Operating conditions that may change during the formation of the bale, however, may affect the number of rotations needed to form a bale of a desired density. These operating conditions may include, but are not limited to, bale size; bale weight; rate of change of bale size; rate of change of bale weight; bale moisture content; rate of incoming crop flow; amount of PTO torque; and rate of fuel consumption.

[0022]Embodiments of the present invention provide an improved system and method of controlling formation of a bale. Embodiments of the present invention minimize the number of bale rotations while still maintaining a desired bale density. Embodiments of the present invention utilize sensors...

Abstract

A method of controlling formation of a bale includes forming a bale from crop material by rotating the bale in a bale chamber and applying an amount of density pressure to the rotating bale. The method also includes receiving at least one operating condition value corresponding to at least one sensed operating condition when the bale is forming. The method further includes automatically determining the amount of bale density pressure applied to the bale responsive to receiving the at least one received operating condition value and controlling formation of the bale by causing the determined amount of bale density pressure to be applied to the bale.

Description

TECHNOLOGY FIELD[0001]The present disclosure relates generally to automatically controlling the formation of a bale in a baler based on sensed parameters, and particularly to automatically determining the density pressure applied to the bale and the speed of the bale chamber via a PTO speed based on sensed parameters.BACKGROUND[0002]Agricultural balers have been used to consolidate and package crop material to facilitate the storage and handling of the crop material for later use. Typically, a mower-conditioner cuts and conditions the crop material for windrow drying in the sun. When the cut crop material is properly dried, a baler, for example a round baler, the most frequently used in industry, is pulled by a tractor and travels along the windrows to pick up the crop material and form the material into cylindrically-shaped round bales.[0003]More specifically, the cut crop material is gathered at the front of the baler from along the ground, onto a pickup assembly, and introduced i...
