Scientists from Perm National Research Polytechnic University have created a system that corrects the position of an excavator bucket in real time, maintaining the optimal cutting angle. As TASS was informed by the university's press service, the novelty combines an electric drive for the teeth, installed directly on the bucket, and a precise positioning radio system that operates on the principle of signal direction finding.
The system tracks the actual position of the bucket, even if the boom has sagged or the hinges are worn. A radio transmitter is placed on the bucket, and receivers are placed on the excavator body. The control unit calculates the exact distance to the platform and the tilt angle based on the signal's travel time. If it deviates from the optimal 30–35 degrees, electric motors, through a system of levers, instantly turn the shaft with the teeth, correcting the angle of attack without the operator's involvement.
Maintaining the correct cutting geometry reduces soil resistance, decreasing the load on the engine and hydraulics. No similar solution has existed in the world until now, as previous systems could not accurately compensate for hydraulic and sensor errors.
The development can be installed on any machine without altering oil pipes and hoses, and a patent for the invention has already been obtained. In the future, this will extend the service life of equipment and reduce fuel consumption across the entire fleet of excavators.
