Multi-level vibration type traditional Chinese medicinal material screening device

The utility model relates to a multi-level vibration type traditional Chinese medicinal material screening device. The multi-level vibration type traditional Chinese medicinal material screening device is provided with a material guide cylinder, a conical pressurization cover and a screening chamber which are sequentially arranged from top to bottom; multiple rows of flexible screening roll devices are sequentially arranged in the screening chamber from top to bottom; each flexible screening roll device corresponds to a screening turbofan in the horizontal and leftward wind direction, the lowermost end of the flexible screening roll devices are horizontally provided with multiple vibration screens in sequence from left to right, and multiple finished product conveying belts are arranged below the vibration screen. By introducing the flexible screening roll devices arranged in a layered mode, after traditional Chinese medicinal materials fall into the device, the traditional Chinese medicinal materials collide through the self gravity function, then the materials will fall on the vibration screens at different positions according to the self weight through the wind action of the screening turbofans, finished products of different sizes or weights are collected through the different finished product conveying belts finally so that the next pharmacy procedure can be carried out, classified screening is efficient, easy and convenient, and the fineness degree is high.
