Detailed Description

The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the utility model and not as limiting the scope of the utility model.

As shown in fig. 1 and 2, a cab axial flow impeller includes a hub; six sets of assembly armed levers 5 are evenly distributed on the outer ring of the hub 4, propeller blades 2 are installed on the back of the top of the assembly armed levers 5 through fixing bolts 6, the propeller blades 2 are of arc-shaped fan blade structures, and corrugated teeth 3 are left on the anticlockwise pointing side edges of the propeller blades 2. The propeller blade 2 of the axial-flow impeller is provided with a plurality of groups of corrugated teeth 3, and compared with the traditional plane blade, the propeller blade can reduce the noise of the air flow by the intersection of the corrugated teeth 3 and the air flow. The contact area between the end face of the propeller blade 2 pointing to the end face anticlockwise and the air flow is large, so that the corrugated teeth 3 are reserved on the end face of the propeller blade 2 pointing to the end face anticlockwise, and the noise of the air flow can be effectively reduced.

As shown in fig. 1 and 2, the clockwise-oriented side edge of the propeller blade 2 is provided with an arc-shaped end surface and a straight end surface, respectively, the clockwise-oriented straight end surface and the arc-shaped end surface of the propeller blade 2 are in a continuous transition structure, and the clockwise-oriented arc-shaped end surface of the propeller blade 2 and the arc-shaped end surface at the top of the propeller blade 2 are in a continuous transition structure. The plane of the propeller blade 2 with the continuous transition structure pointing clockwise can conduct quick flow guiding, and the problem that the working efficiency of the propeller blade 2 is affected due to airflow dispersion caused by the sectional structure is avoided.

As shown in fig. 1 and 2, the hub 4 is fixedly provided with a key shaft sleeve 7 through a bolt 9, a key shaft is inserted into a synchronous shaft hole 1 in the center of the key shaft sleeve 7, and the key shaft is in transmission connection with the hub 4 through the key shaft sleeve 7.
