Claims
- 1. A planer comprising:
- a planer housing comprising:
- a motor compartment;
- a drum compartment having a base plate with a recess;
- a receiving chamber having an outlet opening on at least one side of the planer housing and an inlet opening connecting the receiving chamber to the drum compartment for the intake of chips produced during the planing operation; and
- a chips redirecting surface in the receiving chamber at least approximately opposite to the inlet opening in the direction of the chip intake;
- a motor in the motor compartment;
- a fan wheel connected to the motor;
- a cutter drum in the drum compartment and having a portion of the drum periphery extending through the recess;
- a shaft coupled to the motor, rotatably supporting the drum in the drum compartment and extending parallel to the receiving chamber;
- the chips redirecting surface having at least a part section extending at an inclination in relation to the shaft;
- air passage openings located in the part section; and
- an air channel in the planer housing connecting the air passage openings to the motor compartment so that air flow from the fan wheel passes through the air passage openings and flows in the direction of the outlet opening.
- 2. The planer of claim 1, wherein the part section of the chips redirecting surface is curved in a concave manner when viewed from the inlet opening.
- 3. The planer of claim 1, wherein the air passage openings have the shape of elongated slots located substantially transversely to the extension of the shaft.
- 4. The planer of claim 1, wherein:
- wall areas of boundary walls of the air passage openings remote from the outlet opening run parallel to the inlet direction of the chips into the receiving chamber and
- wall areas of the boundary walls nearer to the outlet opening run at an inclination in the direction of the outlet opening.
- 5. The planer of claim 1, wherein the chips redirecting surface is formed by a wall area of a chips ejection insert which is inserted in a releasable manner into the receiving chamber and which is provided with a passage opening in the area of the inlet opening.
- 6. The planer of claim 5, wherein the chips ejection insert has a tubular portion extending between its end located at the outlet opening and the beginning of the passage opening.
- 7. The planer of claim 5 wherein:
- the planer housing is provided with outlet openings on opposite sides which form the ends of the receiving chamber; and
- the chips ejection insert is alternatively insertable into each of the ends of the receiving chamber for the selective use of one of the two outlet openings for the ejections of chips.
