Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Referring to fig. 1-4, the embodiment of the utility model provides a breaker inner impeller of dust removal function is taken in pivot, including impeller main part, impeller main part both sides all are equipped with

apron

11, 11 central point of apron puts the protrusion and is equipped with

beam barrel

12, 12 central departments of beam barrel link up and are equipped with

shaft hole

13, 12 periphery sides of beam barrel are equipped with a plurality of blade 14.

The blades 14 are spirally distributed, gaps are reserved between the adjacent blades 14, the blades 14 on the two sides are opposite in spiral direction, and when the blades 14 on the two sides rotate, wind power in opposite directions and outward wind power are generated, so that fine sand, debris and dust are driven to be away from the blades.

A plurality of blade groove 16 has been seted up to the outer disc of

shaft

12, 14 grooves of blade are the spiral distribution, and keep away from 11 one side of apron link up, 14 slidable mounting of blade in the blade groove 16, shaft 12 keeps away from 11 one side of apron is connected with spacing ring 17, spacing ring 17 is right blade 14 carries out spacing fixed, does not use during blade 14 or the transportation, can with blade 14 takes off to avoid the damage.
