| 摘要 |
The present invention relates to a crop blower apparatus, and more particularly to an apparatus for blowing crops towards the cutting knives of combine harvesters. The crop blower disclosed has a series of tangential flow blowers aligned along a continuous interconnected sectional drive shaft. The crop blower is mounted to the arms of a combine harvester using a pair of complimentary mounting arms. The sectional drive shaft design facilitates expedited repair work. The crop blower uses peripheral centrifugal blowers to maintain the volume of air flow at the ends of the apparatus to prevent blockage. The perforated metal blower design promotes high levels of air flow, and the positioning of the blowers relative to the discharge duct greatly improves the efficiency of the crop blower apparatus.
