Machine Load Measurement on a Large Square Baler

The disclosure relates to a proposal for measuring the machine load on Large Square Baler (LSB) when the plunger compresses a new flake.

From some LSB it is known to use a single sensor sensing the deflection of the top beam of the machine. However, disadvantageously, this solution cannot give information about driving direction. A further system is known which uses 2 load cells on the side wall of an LSB, and does give information about driving direction. However, the precision on the load measurements are not very high.

With the proposed measuring method the above mentioned disadvantages may be overcome and it provides a reliable method for avoiding machine damage in case of overload on the machine structure and regulates the tension panel pressure.

It is proposed to provide a load measurement by use of load sensors which are placed on the main gear box links which connect the gear box with the chassis, as shown in the picture below.

The load sensors can be load cells or draft pins and they can be placed on the top link or at the bottom link or both.

The plunger force is transferred through the structure to the gear box links.

The load cells or gauges should measure the force in the main direction to measure the exact peak load for a given crank angle. This main direction is given by mathematical basics on the machine.
