A rotating distributor having different jets (20) is mounted on a part (1) of a tree leaf blowing machine. The body, rotated by a motor, supports several differently curved tubes (6,7) provided with a conical nozzle located at their ends which blow air towards the tree. The assembly rotates freely around a hub which has a supply air inlet (10) and slots. When certain tubes are not used and each is neutralised by a plug placed in the nozzle or between the body and the tube. The slots only pass air on a part of the hub. The hub is fixed on the support (17) by a clamp(16). |
