Function of a baler knotters

- A straw baler knotter is responsible for tying the twine around the straw bale. It uses a series of hooks, needles, and billhooks to manipulate the twine and form the knot to secure the twine, ensuring the bale remains compact.

- It feeds the twine from the twine spool through the necessary components to prepare for knot-forming. This involves guiding the twine through tensioners and guides to ensure it is properly positioned

- Once the bale reaches the desired size, the knotter's mechanism is triggered. It uses a combination of rotary and reciprocating motions to tie the knot. The billhook swings around to catch the twine, and the knot is tightened and cut

Material: 40Cr and 42CrMo alloy steels

Function of the baler drive shaft

• The drive shaft is responsible for transmitting mechanical power from the power source (usually a tractor's PTO-Power Take-Off) to the various components of the straw baler.

• It ensures that the rotational energy is efficiently transferred to the baler's mechanisms, such as the pick - up reel, conveyor, and knotters, enabling them to operate in unison.

• The drive shaft must be robust and well-balanced to handle the high-speed rotations and torque requirements of the baling process.

• A yoke is typically used to connect the drive shaft to other parts of the baler, such as the gearbox or the input shaft of the baler's main drive.
