Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0029] refer to figure 1 , this example includes the driven wheel cover 1 and the driving wheel cover 5, the driven wheel cover 1 and the driving wheel cover 5 transition from the axial direction to the radial direction in the form of a circular arc and keep parallel to each other, the driven wheel cover 1 It is connected with the cover plate of the driving wheel 5 through the connecting plate 3 or the connecting column 6. The inner surface of the cover plate of the driven wheel and the cover plate of the driving wheel are respectively equipped with radial blades 2 in the form of arc transition, and the cover plate of the driven wheel 1 and the driving wheel 5 Keep a certain distance between the cover plates (generally determined according to the maximum particle diameter allowed to pass through).
[0030] refer to Figure 1a The radial straight blade...
