  • Conveyor belt system with shock-absorbing belt side travel control means
    Patent number: 5494150
    Abstract: A batter board is interposed between an upper conveyor belt, that is discharging granular material, and a lower conveyor belt that is receiving it. The batter board is adapted to deflect the downwardly arching stream of material, to laterally adjust the location on the lower belt where the material is deposited. The extent of deflection practised is controlled in response to measurements which monitor the downstream belt side travel of the lower belt. The position of the batter board is adjusted with hydraulic actuators protected with a shock absorbing system.
