For solving the problems of the technologies described above, the multi-stage screening system providing comprises frame, its design feature is: the front and rear of frame top is rotatably connected to respectively back shaft and driving shaft, the power set that order about drive shaft turns are housed in frame, crank is equipped with at the both ends of driving shaft, on back shaft, be hinged with the one-level screening basket being obliquely installed, between the rear end of screening basket and upper crank, be hinged with connecting rod, the hopper of accepting that is positioned at one-level screening basket below is housed in frame, the front and rear correspondence of frame is hinged with and is positioned at the suspension arm of accepting hopper both sides, the below of accepting hopper is provided with the secondary sieve basket that at least one deck is obliquely installed, the bottom of secondary sieve basket and one-level screening basket is equipped with screen cloth, on secondary sieve basket, the back shaft being rotatably connected on suspension arm is housed, the oscillatory gearing mechanism that drives suspension arm swing is also housed in frame, the bottom of frame is also equipped with and is positioned at receiving hopper for the secondary sieve basket below of below.
Described oscillatory gearing mechanism comprises the lower crank that is rotatably connected in frame and is connected in frame and engine that driving crank rotates, between lower crank and suspension arm, lower link is housed.
Secondary sieve basket is set altogether, and described one-level screening basket is from going to rear-inclined upwards to arrange, and secondary sieve basket is from going to rear-inclined to arrange downwards, and described receiving hopper is tilted to lower setting from its horizontal opposite side of a horizontal side direction of frame.
Described power set comprise the engine being connected in frame, and the power output shaft of described driving shaft and engine is in transmission connection by sprocket wheel chain.
The bottom of described one-level screening basket is connected with the hinged cover that is inverted U, and described hinged shroud is buckled on back shaft.
Adopt after said structure, material enters from the feed hopper at top, by power set, order about drive shaft turns, by crank, connecting rod drives the front portion of one-level screening basket to teetertotter, when one-level screening basket teetertotters, large granular materials after screening can be unloaded it by the uphill process by its rear portion fast, large granular materials flows out from the inclination lower extending end that goes out one-level screening basket, small particles material leaks down to fall into accept hopper from one-level screening basket bottom, by oscillatory gearing mechanism, order about suspension arm swing again, thereby the swing of secondary sieve basket is screened, the bulky grain of screening flows out from the inclination lower extending end of secondary sieve basket, the material of smallest particles is caught water conservancy diversion by receiving hopper.In sum, the utility model compact conformation, manufacture, installation, easy to operate can be carried out multi-stage screening to material simultaneously, and floor space is little, company investment cost is low, and has advantages of that screening efficiency is high and discharging efficiency is high.
