High efficiency shotpeening machine for the treatment of road and motorway paving, airport runways, car parks and service stations, concrete and steel platbands, surfaces of granite, porphyry and so on

摘要

A shotpeening machine for the treatment of paving surfaces, comprising a shotpeening unit (A) including a feeder of the external air (2,2'), a turbine group (1,1') and a separation group composed of cyclones (4) and sieves (5) , possibly in addition an elevator (6) and a secondary engine/generator group (11) for the hydrostatic transmission; and a suction unit (B) composed of a primary autonomous engine/generator group (8') , a transmission group for the hydrostatic transmission, a box (8) , a fan, an air compressor, filters self-cleaning (9) through compressed air nozzles (10) , a control device to verify the stoppage and automatically control the washing and a reservoir to store the residual materials. The machine can be managed by a system software that controls the flow of air, powders, debris and micro-spheres, separating them, collecting the residual materials and putting the micro-spheres again in circulation, besides to set the working parameters according to the external survey.
