SPREADER OR SPRAYER AND CONTROL SYSTEM THEREFORE
A vehicle mounted spreader for spreading materials such as sand, salt, or other granular chemicals onto snow and ice covered road surfaces comprises a hopper for containing the material to be spread, a spinner for spreading the material, a conveyor for conveying the material from the hopper to the spinner, a vehicle speed sensor, a load sensor, a road condition sensor, and a controller programmed with an intended density of material (e.g., pounds per acre) and desired width of coverage; within the controller the vehicle speed sensor measurement and load and road sensor inputs are processed to generate outputs to control the speed of the conveyor and spinner, to both control the rate of material distribution and the pattern of material distribution to approach the intended density and width. A vehicle mounted sprayer for spreading liquid treatment material for treatment or pre-treatment of road surfaces comprises a plurality of tanks for containing main brine material to be spread, a hot mix tank supplying hot mix, a mix valve for mixing the main brine and hot mix, pumps for controllably delivering main brine and hot mix to the mix valve, and a flow sensor for measuring the flow rate of liquid treatment material. In this case the controller determines the intended density and flow rate of liquid based on sensor inputs.
