Abstract
The invention pertains to a device and procedure to regulate the bale length in a square baler. Sensors determine both the forward and backward movement of the crop bundle and transfer these measurements to an evaluation electronic. The evaluation electronic adds the measurements and triggers the tying process when the actual length value is reached. The procedure includes the steps of: sensing both the forward and backward movement of a crop bundle in a baling chamber; adding the measured forward and backward movements to determine an actual length value of the crop bundle; and triggering the tying device once a pre-set target actual length value is reached.
Claims11
In a square baler for baling harvested crops and having a pick-up device, a feeding channel, a baling chamber, a baling ram for forming a crop bundle in the baling chamber, and a tying apparatus for tying the crop bundle and forming a bale;
- the improvement comprising:
- sensing means including a symmetrical measuring wheel for sensing both forward and backward movements of the crop bundle in the baling chamber;
- means for determining an actual length value of the crop bundle and triggering the tying apparatus when a pre-set length for the crop bundle is reached;
- and
- the sensing means including an electronic measuring device which measures, via the rotational movement and the direction of rotation of the measuring wheel, the forward and backward movements of the crop bundle in the baling chamber.
A baling method for controlling the length of a square bale, comprising the steps of:
- providing a measuring wheel;
- sensing the measuring wheel's rotary movement and direction of rotation and thereby sensing both the forward and backward movement of a crop bundle in a baling chamber;
- adding the measured forward and backward movements of the crop bundle to determine an actual length of the crop bundle;
- and triggering a tying device once a pre-set target length value is reached to tie the crop bundle into a bale.
