Surface processing device

Abstract

A surface processing device comprising at least: a cylinder-shaped blast housing provided with the 1st opening and the 2nd opening; an annular vacuum seal which seals the gap between the blast housing and the object surface; a nozzle which injects surface processing substances toward the object surface; a parallel motion mechanism to make the nozzle be reciprocated in parallel along the object surface; a sheet belt for covering the 2nd opening; and a vacuum generating means for decompressing the space enclosed by the object surface, the blast housing, the vacuum seal and the sheet belt. Therein, a traveling means such as drive wheels is provided, the parallel motion mechanism to make the nozzle be reciprocated in parallel along the object surface in a direction that intersects with the traveling direction of the surface processing device, and the nozzle is also reciprocated in a direction that intersects with the direction in which the nozzle is reciprocated in parallel along the object surface.

1 . A surface processing device, comprising:
 a cylinder-shaped blast housing provided with the 1st opening which is formed on the side which faces the object surface and the 2nd opening which is formed on the opposite side of the object surface;   an annular vacuum seal which is provided with the 1st opening and which seals the gap between the blast housing and the object surface;   a nozzle which injects surface processing substances such as abrasives or thermal spray coating material toward the object surface;   a parallel motion mechanism to make the nozzle be reciprocated in parallel along the object surface;   a sheet belt for covering the 2nd opening and which is provided with the hole the nozzle pierces; and   a vacuum generating means for decompressing the space enclosed by the object surface, the blast housing, the vacuum seal and the sheet belt,   wherein a traveling means such as drive wheels is provided,   the parallel motion mechanism to make the nozzle be reciprocated in parallel along the object surface in a direction that intersects with the traveling direction of the surface processing device, and   the nozzle is also reciprocated in a direction that intersects with the direction in which the nozzle is reciprocated in parallel along the object surface.
