Abstract

A sprinkling device (1) serves to load cutting heads (2) which are equipped with drilling bits 31-35 for use in mining, tunnelling and civil engineering. The sprinkling device (1) has a plurality of nozzles 21-25 which are arranged next to one another on a sprinkling pipe (3) and from which in each case one spray cone 41-45 emerges which is directed onto the cutting head (2) and comprises a water/air mixture. The centre line 61-65 of the spray cones which emerge from the nozzles 21-25 are directed onto a position between tangentially onto the basic body (5) of the cutting head (2) and onto the tip 51-55 of the respective drilling bit 31-35.

Abstract

The invention relates to a spraying device (1) that is used to spray machine parts (5) or at-risk areas in mining, tunnel construction, and civil engineering. The spraying device has a plurality of nozzles (2, 3, 4), from each of which a spray cone (6, 7, 8) of a water-air mixture directed at the at-risk machine part (5) or the at-risk area is discharged. The nozzle (2, 3, 4) has an elongated housing (9) having a central channel (11), the rear end (12) of which is used to connect to a water supply and the front end (13) of which is used to discharge the water-air mixture. The housing (9) has a plurality of holes (14, 15, 16) for supplying air, which are positioned evenly over the circumference of the nozzle (2, 3, 4) and which open laterally into the channel (11).

Abstract

The invention relates to a roadheader (1) used in mining. The roadheader comprises a machine frame (3), which on the end thereof that faces the working face has a cutting device (5) arranged on a swivel arm (4). Viewed in the longitudinal-axis direction, a control stand (6), an electrical unit (9) designed as a kiosk substation (10), and/or a drilling-/anchor-setting unit (2) are arranged next to each other on the machine frame (3).

Abstract

The invention relates to a shearer loader device (1) used in mining. The shearer loader device comprises a frame (4), which is provided with cutting drums (5, 6) at the ends of the frame and is used to accommodate at least one drilling/anchor-setting unit (2). The drilling/anchor-setting unit is movably arranged on the frame (4) and has end positions in the form of a parking position inside the contours of the frame (4) and a maximum working position outside the contours of the frame (4) and beyond the cutting drums (5).
