6-Bit Hydraulic Manifold and Its Use in Spreading Salt

摘要

Disclosed is a system for precisely controlling distribution of saline, which employs a 6-bit manifold employing 6 solenoid valves for controlling the flow of hydraulic fluid therethrough. The manifold is in hydraulic fluid communication with motor valves. A mathematical formula or a lookup table determines the amount of saline distributed. The system is devoid of feedback. The 6-bit manifold can be employed on a salt spreader vehicle for controlling an improved flighted auger assembly for distributing granular salt from the rear of a salt spreader vehicle. The auger assembly has 3-stages of increasing diameter flights. The largest flight is at a discharge end of the auger assembly. A choke surrounds the ultimate auger flight at the auger assembly discharge end. The space between the choke and the ultimate flight is between about ⅛ and ¼ inch.

1. A system for precisely controlling distribution of saline, which comprises:
a 6-bit manifold comprising 6 solenoid valves for controlling the flow of hydraulic fluid therethrough, said manifold in hydraulic fluid communication with motor valves for controlling the distribution of saline in the form of one or more of granular salt or brine, the amount of saline distributed being determined by a mathematical formula or a lookup table, said system devoid of feedback.
