Course dependent bulk material scattering unit - has independent current supply for electric motor driven conveyor belt and regulating motor

摘要

The mechanism is devised for controlled scattering of sand, salt, road surface binding media or other granular material on roads. It is mounted on a vehicle, with a conveyor belt, with drive dependent on the course followed, leading to a motor-driven scatter-tray with a down-pipe. The vehicle carries an independent current supply system and the conveyor belt is driven by a control gear with an electric motor, with a regulating motor for control. For regulation of this motor there is an automatic control device comparing tension level deriving from the motor control gear with tension level dependent on the speed of travel and adjusting the regulating motor according to the differential factor.
