Description
Technical field
The present invention relates to the meticulous screening machine of a kind of multi-stage screening.
Background technology
At present, the structure of existing screening machine comprises frame, is elasticly connected with screening basket in frame, on screening basket, vibrating motor is housed, and the vibrations by vibrating motor make screening basket produce shake, thereby realize the screening of material.Because the vibration frequency of vibrating motor is too frequent, there is the shortcoming that screening efficiency is low while sieving for the larger material of grain graininess difference in the screening machine of this structure, and the screening basket nature discharging that need to be obliquely installed of this screening machine, and discharge rate is slow.And when needs carry out multi-stage screening, existing screening machine is difficult to process, and a plurality of screening machines need to be set in parallel by belt conveyor, and its floor space is large, investment is large, causes production cost to increase.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of screening efficiency is high, discharge rate is fast and the meticulous screening machine of multi-stage screening of multi-stage screening simultaneously.
For solving the problems of the technologies described above, the meticulous screening machine of multi-stage screening 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 both lateral sides of frame is symmetrical two stock guides stretching under its horizontal side direction opposite side tilts that are equipped with also, stock guide sieves basket and accepts between hopper in one-level, the material baffle between stock guide rear portion is equipped with at the rear portion of 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.
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, the guide effect that small particles material leaks down from one-level screening basket bottom at stock guide falls into be accepted in hopper, 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, arranging of stock guide effectively prevents being scattered of the one-level rear material of screening everywhere, arranging of material baffle can effectively prevent rerolling phenomenon.In sum, compact conformation of the present invention, 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.
Accompanying drawing explanation
