Claims11
A drilling machine for drilling holes in structural building elements, such as concrete floors or walls, comprising
- a. a frame structure (2, 3) in which a drilling bar (18) having a cutting bit is displaceably mounted for movement relative to the structural element;
- b. a container (22) which at least partially surrounds said drilling bar (18) and which is adapted to collect the cooling liquid used to cool said cutting bit of said drilling bar and to collect the slurry fromed during a drilling operation, said container (22) including a bottom plate (20) arranged to face towards the structural element and having a circular opening (20a) which receives said drilling bar (18);
- c. a collar (27) arranged in said opening (20a) having an inner surface for blocking the cooling liquid and slurry mixture thrown off by said drilling bar, said collar further having an upper edge over which the mixture is fed to the interior of said container (22) to form a substantially stationary reservoir therein;
- and
- d. an outlet (28) in said container (22) for draining the reservoir from said container (22).
