Abstract
A description is given of an extraction device (1) for a core drill, including a housing (4) which has at least one cavity (7), a cover (2) and a wall (3) connected to the cover (2) around the periphery. An extraction nozzle (5) connected to the housing (4) is provided, designed for attaching the extraction device (1) to a suction device. The wall (3) has at least one inlet opening (44, 45), by way of which the cavity (7) is connected to the surroundings (U). The wall (3) has a first substantially planar wall region (10) and a second substantially planar wall region (11), wherein a surface (14) of the first wall region (10) that is facing away from the cavity (7) forms an obtuse angle (16) with a surface (15) of the second wall region (11) that is facing away from the cavity (7).
Claims21
An extraction device for a core drill, the extraction device comprising:
- a housing having at least one cavity, a cover and a wall connected to the cover around a periphery of the cover so as to surround the cavity, the cavity being open within an edge of the wall on a side facing away from the cover, the cavity being open opposite the cover for positioning on a surface to be drilled by the core drill;
- an extraction nozzle connected to the housing, the extraction nozzle for attaching the extraction device to a suction device;
- the wall having at least one inlet opening, the cavity being connected to surroundings of the extraction device via the at least one inlet opening;
- the wall having a planar first wall region and a planar second wall region, a surface of the first wall region facing away from the cavity forming an obtuse angle with a further surface of the second wall region facing away from the cavity.
