Electronically controlled bulk material scattering unit - with proportional valves in fluid power circuits and interference influenced logic system

摘要

The vehicle carries an independent drive assembly and there are automatically regulated proportional valves in the individual fluid circuits driving a scatter tray and conveyor belts. The control mechanism for this incorporates an electronic logic system to distribute the material on a basis of multiplication of interference variations, including density of scatter, width of scatter and tachogenerator-controlled speed. The drive assembly may comprise a diesel engine driving pumps combined to form a dual-circuit axial-piston pump. The unit can be readily mounted on standard lorries and other vehicles.
