It is fallen on strainer under gravity, the strainer retains large-size particle, passes through small sized particles, therefore, small sized particles
It is exported by the discharge port of lower part, since strainer is obliquely installed, large-size particle slides into strainer low side, due to the resistance of position limiting structure
Gear effect, large-size particle is collected in strainer low side, after being collected into a certain amount of, opening door closure, and sliding slider to the other end,
The large-size particle of strainer low side is struck off opening export by the scraping blade.
The utility model is filtered by the way that strainer is arranged below shaft to by the smashed medicine particle of crushing knife,
By small sized particles, large-size particle is retained, since strainer is obliquely installed, large-size particle slides into strainer low side, due to
The barrier effect of position limiting structure, large-size particle is collected in strainer low side, will by sliding scraping blade after being collected into a certain amount of
The large-size particle of strainer low side strikes off opening export, it is ensured that the filter effect of strainer avoids accumulating excessive ruler on strainer
It is very little that strainer is caused to fail, in this way, the utility model solves the problems, such as that existing pulverizer causes particle size after crushing inconsistent.
Further, crushing chamber includes symmetrically arranged upper frame body and lower frame body, and the upper frame body and lower frame body are detachable
Formula connection, the shaft are arranged in upper frame body, and the strainer is arranged in lower frame body, on two symmetrical sides of the strainer
It is provided with fixed plate, multiple positioning columns are provided in the fixed plate, is provided on the side wall of the lower frame body and matches with positioning column
The trench bottom of the fixing groove of conjunction, the fixing groove is provided with elastic component.
The detachable setting of strainer is realized by the cooperation of fixed column and elastic component, by the way that crushing chamber to be set as including pair
Claim the upper frame body and lower frame body of setting, the upper frame body and lower frame body detachable connection, is conveniently replaceable strainer, it is not only replaceable
The strainer of different pore size, moreover it is possible to replace the strainer of failure.
Further, the outer wall of upper frame body and lower frame body is provided with connecting plate, passes through lead screw and spiral shell between 2 connecting plates
Connection is realized in the cooperation of cap.
Further, it is provided with sliding slot on two symmetrical sides of through slot, the both ends of the sliding block are provided with matches with sliding slot
The ball of conjunction, the ball can move in sliding slot.
Further, arc transition between position limiting structure and strainer, the bottom of the scraping blade are globoidal structure.
Above-mentioned setting is conducive to reduce resistance when scraping blade sliding, strikes off efficiency to large-size particle convenient for improving.
Further, crushing chamber is square structure.
Square structure, which is set, by crushing chamber is conducive to installation strainer.
Further, feed inlet is funnel structure.
The feed inlet of above structure is conducive to import material.
The utility model compared with prior art, has the following advantages and benefits:
The utility model is filtered by the way that strainer is arranged below shaft to by the smashed medicine particle of crushing knife,
By small sized particles, large-size particle is retained, since strainer is obliquely installed, large-size particle slides into strainer low side, due to
The barrier effect of position limiting structure, large-size particle is collected in strainer low side, will by sliding scraping blade after being collected into a certain amount of
The large-size particle of strainer low side strikes off opening export, it is ensured that the filter effect of strainer avoids accumulating excessive ruler on strainer
It is very little that strainer is caused to fail, in this way, the utility model solves the problems, such as that existing pulverizer causes particle size after crushing inconsistent.
