In traditional machinery, such as an agricultural harvester, when the equipment works, stems and leaves of harvested crops are often sucked into an engine bin by an engine cooling fan and attached to the surfaces of an engine and a radiator, so that the engine is easy to be at high temperature, and the equipment has the risk of spontaneous combustion. One mode is a manual cleaning mode, so that the difficulty is high and the efficiency is low; in another mode, the fan steering is changed, but the auxiliary working face plays a main role after the fan steering is changed, so that the air quantity is greatly reduced, and the actual requirements cannot be met.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides the fan blade, by arranging at least one windward rib on the auxiliary working surface, the air quantity of the auxiliary working surface is increased, so that the fan can still output enough air quantity after turning, the actual requirement is met, the strength of the blade body can be increased, the thickness of the blade body is reduced, and the power consumption is reduced.
The technical scheme of the utility model is realized as follows: the utility model provides a fan blade, includes the blade body, and the blade body includes main working face and vice working face, and the one end of blade body is equipped with the fixing base, is equipped with at least one rib that faces wind on the vice working face, and the rib that faces wind includes plane portion and bending portion, and the plane portion sets up along the length direction of blade body, and bending portion is crooked to the fixing base and with the fixing base contact.
As a further improvement of the above technical scheme:
the width of the bending part gradually decreases from the connecting part with the plane part to the contact part with the fixing seat.
The height of the fixed seat higher than the main working surface is larger than the height of the fixed seat higher than the auxiliary working surface.
The height of the plane part is larger than that of the fixing seat higher than that of the auxiliary working surface.
The height of the fixing seat higher than the main working surface is 10mm.
The height of the fixing seat higher than the auxiliary working surface is 5mm.
The width of the planar portion is 50mm.
And a mounting hole is formed in the fixing seat.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the advantages that: by arranging at least one windward rib on the auxiliary working surface, the air quantity of the auxiliary working surface is increased, so that the fan can still output enough air quantity after turning, the actual requirement is met, the strength of the blade body can be increased, the thickness of the blade body is reduced, and the power consumption is reduced; in addition, the height of the windward rib is larger than the height of the fixing seat higher than the auxiliary working surface, so that the fixing seat cannot influence the air output because of too high height.
The utility model is further described below with reference to the drawings and the detailed description.
