Abstract
The object of the present invention is to provide a high volume, low cost, sealant spray control system for the asphalt industry, accomplished particularly through a self contained vehicle mounted spray system utilizing a digital positioning receiver consisting of a global positioning system (GPS) or horn radar for vehicle speed sensing and a motor RPM sensor and a program logic CAN micro controller for adjusting output flow of a material pump to achieve a target application spray rate of a spray bar.
Claims1
A self-contained vehicle mounted spray system, comprising:
- a spray material storage tank;
- a spray apparatus;
- a spray material pump located between said storage tank and said spray apparatus;
- a hydraulic motor for driving said spray material pump;
- a dedicated prime mover for the spray system;
- an RPM sensor for sensing rotation of said hydraulic motor;
- a digital positioning system comprising one of a global positioning system and a horn radar for wirelessly sensing a speed of the vehicle to which the spray system is mounted;
- and
- a micro controller;
- wherein said micro controller receives input information from said RPM sensor to determine an output flow of said spray material;
- wherein said micro controller receives input information from said digital positioning system regarding the speed of the vehicle;
- and
- wherein said micro controller proportionally adjusts a spray material flow to said spray apparatus based on the input information from said RPM sensor and said digital positioning system in order to meet a predetermined target spray application rate.
