Specifically, the present invention is achieved through the following technical solutions：
A kind of sand-proof device of Pump Shaft, including water pump body（300）And main shaft（200）, water pump body（300）Top
End is provided with top cover（301）, described top cover（301）On be provided through top cover（301）And main shaft can be made（200）What is passed through is logical
Hole, it is characterised in that described top cover（301）Through hole is provided with sand prevention bulge loop（400）, described main shaft（200）On
It is socketed with an anti-sand sleeve（100）, described anti-sand sleeve（100）On offer and sand prevention bulge loop（400）The groove of adaptation（104）,
The sand prevention bulge loop in assembling（400）It is placed in anti-sand sleeve（100）Groove（104）It is interior.
It is further to above-mentioned technical proposal to be designed：Described anti-sand sleeve（100）Including at the top of sand prevention（102）, sand prevention
Tapered portion（101）With sand prevention bottom（103）, described anti-sand sleeve（100）Main shaft can be made by offering（200）The sand prevention hole run through
（105）, at the top of described sand prevention（102）Sand prevention hole（105）Diameter be more than sand prevention tapered portion（101）Sand prevention hole（105）
Diameter, described sand prevention bottom（103）Sand prevention hole（105）Diameter be more than sand prevention tapered portion（101）Sand prevention hole（105）
Diameter.
It is further to above-mentioned technical proposal to be designed：Described anti-sand sleeve（100）It is made up of rubber, described sand prevention is convex
Ring（400）It is made up of ceramics.
The beneficial effects of the invention are as follows：Pass through anti-sand sleeve（100）With sand prevention bulge loop（400）Structure prevent the debris from entering
Whose stupid inside, meanwhile, its ceramic material can ensure that dustproof effect and service life.And anti-sand sleeve（100）Sand prevention top
Portion（102）Design can effectively accumulate after debris and throw away debris by centrifugal motion, and sand prevention tapered portion（101）Can be effective
Wrap main shaft（200）Prevent debris from entering, and sand prevention bottom（103）Design by with sand prevention bulge loop（400）Cooperation come
Now further sand prevention purpose.
