Abstract
A suction tube nozzle comprising at least a conduit with an inlet, an outlet and a conduit wall enclosing a conduit volume. conduit wall has a first end defining the inlet and a second end defining the outlet and an inner wall surface. The second end is configured to be connected to a distal end of a suction tube to thereby provide a fluid communication between the inlet and the suction tube. Insects sucked into the inlet are reliably cut in pieces if a first rotary bearing with a first rotational axis movably supports at least one first rotary blade inside the conduit volume relative to the conduit wall.

A suction tube nozzle comprising
- at least a conduit with an inlet, an outlet and a conduit wall enclosing a conduit volume, wherein:
- (i) the conduit wall has a first end and a second end and an inner wall surface,
- (ii) the first end defines the inlet, and the second end defines the outlet, and
- (iii) the second end is configured to be connected to a distal end of a suction tube to thereby provide a fluid communication between the inlet and the suction tube,
- (iv) a first rotary bearing with a first rotational axis movably supports at least one first rotary blade inside the conduit volume relative to the conduit wall,
- characterized in that
- the suction tube nozzle further comprises a static blade with at least a first and/or a second static cutting edge, wherein the first static cutting edge faces towards a first rotary cutting edge of the first rotary blade and/or a second rotary cutting edge faces towards a static cutting edge of the second static blade.
