  • Patent number: 10829312
    Abstract: An autonomous tensioner system that is coupled to a conveyor belt scraper includes a motor that generates a first drive torque and a gearing assembly coupled to the motor such that the gearing assembly is actuated in response to the motor generating the first drive torque. The gearing assembly generates a second drive torque in response to receiving the initial drive torque generated by the motor and the second drive torque is greater than the first drive torque. The autonomous tensioner system includes an output member coupled to the gearing assembly and the conveyor belt scraper. The output member receives the second drive torque from the gearing assembly and rotates in response, thereby generating a rotational torque. The conveyor belt scraper receives the rotational torque from the output member and simultaneously moves at a torque greater than the first drive torque generated by the motor.

  • Patent number: 9604262
    Abstract: A combination air cannon and sonic horn for dislodging accumulated bulk material comprises an air cannon, a sonic horn, and a shared portion. The air cannon is configured to store pressurized gas and to periodically abruptly discharge the pressurized gas through a gas outlet. The sonic horn is configured to generate sound waves that that are emitted from the gas outlet. The outlet is formed on a nozzle having a unique configuration. The outlet can be oriented such that blasts of air from the air cannon pass over the accumulated bulk material and lift the bulk material into suspension via Bernoulli's law.

  • Patent number: 9409713
    Abstract: A conveyor belt assembly comprises a conveyor belt, a tail pulley, and a transition zone comprising a loading device. The conveyor is looped around the tail pulley and has a generally flat transverse cross-section on the tail pulley. The conveyor belt transitions from having the generally flat cross-section to having a full-trough cross section in the transition zone. The loading device comprises a chute and skirtboards that are connected to each other and that are above the conveyor belt. The loading device is configured to load bulk material onto the belt in the transition region. The skirtboards have linear bottom surfaces that rise as the distance from the tail pulley increases. The conveyor belt is supported from below in the transition zone in a manner creating linear portions of the conveyor belt directly beneath the skirtboards that also rise as the distance from the tail pulley increases.
