Abstract
A material collection system is provided. The system can include a vehicle, a conduit, a vacuum generator mounted to the vehicle to develop an airflow and to draw material into the conduit, and a moveable boom mounted to the vehicle to support the conduit. The system can include a control system to control a speed of the vacuum generator.
Claims9
A method for operating a material collection system, comprising:
- operating a vacuum generator at a first speed, the first speed being a work mode where the vacuum generator develops an airflow to draw material into a material inlet of a conduit;
- receiving, at a control system, a first signal from a sensor indicating a travel speed of the material collection system;
- receiving, at the control system, a second signal from a timer indicating a time duration of the first signal;
- generating, at the control system, a third signal indicating the vacuum generator is not in the work mode based on the first signal and the second signal;
- and
- controlling, by the control system, the speed of the vacuum generator to a second speed less than the first speed based on the third signal.
