Abstract
A road marking removal system creating a blasting mixture by injecting particulate matter from a media hopper into flowing compressed air. The blasting mixture is directed at a road marking via a blasting nozzle. The nozzle discharges the blasting mixture from within a marking removal head housing. A vacuum is applied to an interior of the marking removal head housing for collecting the residual material created by the removal process. The residual material consists of particulate matter, road marking debris, and the like. The collected material can optionally be sorted with material of an acceptable size being reclaimed and forwarded to the media hopper for reuse. The road marking removal system can be manually operated being integrated into a cart, or remotely operated when integrated into a vehicle.
Claims19
A road marking removal system comprising:
- a carrier vehicle comprising a frame and a plurality of wheels;
- a marking removal head housing having a media inlet port in fluid communication with a blasting nozzle and a vacuum particle retrieval port for extracting residual particles, the marking removal head housing being
- operably mounted to the carrier vehicle via at least one repositionable member, the operable mounting further comprising a slide interface rail horizontally configured and transversely mounted to a leading portion of the vehicle;
- an air compression unit mounted to the carrier vehicle;
- a solid media hopper for injecting solid media into a media delivery conduit, the media conduit providing fluid communication between the air compressor unit and the media inlet port, the solid media hopper being mounted to the carrier vehicle;
- a vacuum unit mounted to the carrier vehicle;
- and
- a vacuum conduit providing fluid communication between the vacuum particle retrieval port and the vacuum unit.
A road marking removal system comprising:
- a carrier vehicle comprising a frame and a plurality of wheels;
- a marking removal head housing having a media inlet port in fluid communication with a blasting nozzle and a vacuum particle retrieval port for extracting residual particles, the marking removal head housing being
- operably mounted to the carrier vehicle via at least one repositionable member, the operable mounting further comprising a slide interface rail horizontally configured and transversely mounted to a leading portion of the vehicle and a pivotal arm having the marking removal head housing assembled to a removal end of the pivotal arm and a frame mount assembled to a frame end of the pivotal arm, wherein the frame mount is slideably assembled to the slide interface rail;
- an air compression unit mounted to the carrier vehicle;
- a solid media hopper for injecting solid media into a media delivery conduit, the media conduit providing fluid communication between the air compressor unit and the media inlet port, the solid media hopper being mounted to the carrier vehicle;
- a vacuum unit mounted to the carrier vehicle;
- and
- a vacuum conduit providing fluid communication between the vacuum particle retrieval port and the vacuum unit.
A road marking removal system comprising:
- a carrier vehicle comprising a frame and a plurality of wheels;
- a marking removal head housing having a media inlet port in fluid communication with a blasting nozzle and a vacuum particle retrieval port for extracting residual particles;
- an interior working area formed within the marking removal head housing by a peripheral sidewall being contiguous and extending downward from a top portion;
- an air compression unit mounted to the carrier vehicle;
- a solid media hopper for injecting solid media into a media delivery conduit, the media conduit providing fluid communication between the air compressor unit and the media inlet port, the solid media hopper being mounted to the carrier vehicle;
- a vacuum unit mounted to the carrier vehicle;
- a vacuum conduit providing fluid communication between the vacuum particle retrieval port and the vacuum unit;
- and
- a mounting mechanism having the marking removal head housing disposed at a working end of the mounting mechanism and a vehicle mount disposed at a mounting end of the mounting mechanism, the mounting mechanism further comprising a mounting frame slide rail being transversely mounted to a leading portion of the vehicle, wherein the vehicle mount slideably engages with the mounting frame slide rail, and wherein the mounting mechanism provides lateral, longitudinal, and height movements to the marking removal head housing.
