FIELD: equipment used in vacuum cleaning apparatuses, may be employed in centralized dust removal systems.
SUBSTANCE: tip has trapezium-shaped case with opening provided in its smaller base and suction slit provided in its larger base and aligned with upper slit formed in sealing device. Sealing device is formed as pipe with lower slit extending along its side surface. Lower edge of said surface is arranged on vertical axis of symmetry of pipe cross-section plane. Upper edge of lower slit is arranged on inclined axis at an angle to vertical axis of symmetry of cross-section plane.
EFFECT: simplified construction and increased wear resistance of dust removing tip during operation with surfaces covered with dust containing abrasive particles.
