Description
Technical field
The utility model relates to solid granulates sample (granular potassium sulfate, coal) grinding device, especially mini pulverizers.
Background technique
The still not enough optimization, perfect, conjunction in structure of existing solid granulates sample (granular potassium sulfate, coal) grinding device
Reason, working life are partially short, it would be highly desirable to improve.
Utility model content
The purpose of this utility model is to provide a kind of mini pulverizers, the more optimization, perfect, reasonable, work in structure
Make that the service life is long, and by hand-held operation, flexibly and easily, not by constraint based on sites, use scope is extensive.
Purpose of the utility model is realized as follows: a kind of mini pulverizer, by the lithium battery structure that can be charged repeatedly
At charge power supply with discharge direct current supply dc motor the wired electrical connection dc motor of mode, in dc motor
Front end is fixedly mounted with the cylinder for covering the power output shaft that dc motor front end is provided with, the rear end nozzle end wall of cylinder and straight
Stream motor casing peripheral wall front end seamless seal is fixed together, and set is filled with the axis of rolling on the power output shaft of dc motor
It holds and the annular sealing member immediately ahead of rolling bearing, the outer ring of rolling bearing and the inner peripheral surface of cylinder is fixed together, roll
The inner ring of dynamic bearing is looped around on power output shaft and is fixed together with power output shaft, and power output shaft is through annular sealing member
Across annular sealing member, the inner peripheral surface of annular sealing member outer peripheral surface and cylinder, which seals against each other, is fixed on one for the perforation that middle part is provided with
It rises, annular end face is fixed together on front side of the outer ring surface of the rear side annular end face of annular sealing member and the outer ring of rolling bearing, ring
The inner ring surface of the rear side annular end face of shape seal is in a manner of around power output shaft rotation and on front side of the inner ring of rolling bearing
The cooperation of annular end face dynamic sealing, the perforation inner peripheral surface of annular sealing member is in a manner of surrounding power output shaft rotation and power output
The cooperation of axis outer peripheral surface dynamic sealing, power output shaft front end are connected through a screw thread part coaxially affixed supporting drive shaft, are driven in bearing
The front end of axis is coaxially fixedly mounted with quantity and is two panels or more and the reamer hanging in cylinder by supporting drive shaft, and reamer is around branch
The front end circumferential direction for holding transmission shaft is uniformly distributed.
The utility model grabs steady dc motor casing when in use, by hand, will granular potassium sulfate, coal etc. it is solid
State particulate samples are put into cylinder through barrel front end nozzle, are opened dc motor and are passed through its power output shaft and supporting drive shaft
Reamer rotation is driven, then further crushes the major diameters solid granulates sample such as granular potassium sulfate, coal as minor diameter
Grain sample；When the utility model crushes solid-state bulky grain sample, the excellent sealing and its and power of annular sealing member and cylinder
The excellent sealing of output shaft can effectively prevent the dust that solid-state bulky grain sample generates during pulverized and enter bearing and straight
It flows in motor casing.
The utility model more optimization, perfect, reasonable, long working life in structure, it is flexibly square by hand-held operation
Just, it is not sampled in extensive range by constraint based on sites.
Detailed description of the invention
