Preferably, the vibrating screen assembly includes a sieve plate, the outer wall of the sieve plate is movably connected to a crankshaft assembly through a shaft, the bottom of the crankshaft assembly is connected to an eccentric wheel, and the eccentric wheel is fixed on the output end of the drive motor.

Preferably, the crankshaft assembly includes two groups of movable shafts, and the two groups of movable shafts are movably connected by pins.

Preferably, the top of the rotary separator is provided with a feed inlet, and the center of the inner cavity of the rotary separator is vertically provided with a mounting shaft, and the outer wall of the mounting shaft is welded with a spiral separation plate. There is a discharge port at the bottom of the separator.

Compared with the prior art, the beneficial effect of the utility model is: the utility model pours chaff (containing rice husks and broken rice) onto the upper vibrating screen of the separation chamber, and the equipment operates, using the vibrating principle of the vibrating screen, crushing The rice falls through the small holes of the upper vibrating sieve to the lower vibrating sieve, and is screened by the vibrating sieve again. The broken rice passes through the small holes on the vibrating sieve and falls into the primary broken rice recovery box. The fan is sucked into the connecting pipe. At this time, the inhaled husk contains a small amount of broken rice. When the husk passes through the other end of the connecting pipe, it is screened again by the rotary separator to separate the husk and a small amount of broken rice. Broken rice It will directly fall into the secondary broken rice recovery box, and the grain husk will be sucked into the conveying pipe through the exhaust fan, so as to fall into the grain husk recovery box. The utility model improves work efficiency, consumes less energy, and reduces costs.
