A kind of improvement of Chinese medicine extracter,Mainly include: a cylinder,What one end is equipped with a control outlet,Another end is then equipped with an axis hole; One transmission shaft,System with oil sealing,Bearing,The shaft components such as shaft coupling are pivoted at the axis hole of what cylinder,The transmission shaft one end is equipped with blade and protrudes into the inner barrel,And the another end of rotary shaft then connects with motor and deceleration mechanism,And by the Hou of motor driven deceleration mechanism,Drive blade turn in cylinder of rotary shaft; Its characteristic is in what: be between the rotary shaft and deceleration mechanism equipped with a positive and negative rotational mechanism,Enable the blade of transmission shaft continuously rotated forward in cylinder and reversion movement,Make persistently to carry out fierce stirring in cylinder,Effectively quickly the medicinal ingredient of object to be extracted can be extracted,And save the energy.一種中藥萃取機之改良,主要包含有:一筒體,於一端設有一控制出口,另端則設有一軸孔;一傳動軸,係以油封、軸承、聯軸器等軸構件樞設於筒體的軸孔處,該傳動軸一端設有葉片伸入該筒體內部,而旋轉軸的另端則與馬達及減速機構相接,並藉由馬達傳動減速機構之後,帶動旋轉軸之葉片在筒體內旋動;其特徵在於:該旋轉軸與減速機構之間係設有一正反轉機構,使傳動軸之葉片得以在筒體內進行連續的正轉及反轉動作,使筒體內持續進行激烈的攪拌,能有效而快速的將待萃取物的藥用成分萃取出來,並節省能源。
