摘要

The device is for the removal of shotblast particles from beneath a grid and has channels (3) funnel-shaped in cross-section arranged at a distance from the basic surface so that the wide aperture (6) faces the grid and the narrow aperture as an outlet opening (5) faces the basis surface. In the narrow aperture is arranged a hollow body (4) with an elastic walling and a connecting component for feeding and evacuating a fluid or gas-form material. The space between the basic surface and the funnel-shaped grooves is provided with a connection for a suction device (7).
