Abstract
A cutter machine has cutter heads or rollers rotatably mounted on a pivoting cutter arm. It also has a loading ramp and a conveyor running in a direction towards the work face of the cutter machine to take up and convey away cut material. The cutter arm is mounted on a sliding carriage which is displaceable along guides running in the longitudinal direction of the machine. The carriage is configured as a self-supporting box profile in a clear cross-section space of which a removal conveyor is mounted so that it may slide. For this reason, the cutter machine is particularly well-suited for use in small seam heights and for particularly low constructional design. It may nonetheless be used satisfactorily for operating reliably over a variable tunnel width.
Claims17
A cutter machine comprising:
- a main frame;
- guides mounted on said main frame and running in a longitudinal direction of the machine;
- a sliding carriage configured in a self-supporting box configuration over said main frame and displaceable along said guides;
- a pivoting cutter arm mounted on said carriage;
- cutting means rotatably mounted on said pivoting cutter arm;
- and
- a loading ramp and a removal conveyor running from a work face of said machine for taking up and conveying away material cut by said cutting means, the removal conveyor being mounted in a clear interior space of the carriage so that the carriage may slide independently of the removal conveyor.
