The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

A kind of differential double-deck wind-force dry-dressing machine as shown in the figure, frame 2 is the frame-type structure, hang two gear frames 3 from top to bottom respectively by hanging vibration damping adjusting device 6 on it, on each gear frame 3 sorting bed 4 is housed all, these sorting bed 4 its bed surfaces are rectangle, be covered with sawtooth pattern rubber sieve plate 26 with holes on it, be pressed with parallel have certain angle and height, dividing plate 27 uniformly at interval on the

sieve plate

26,27 on dividing plate forms cell body, described sieve plate 26 wearabilities are good, the coefficient of friction height, its serrated slot helps the discharge of material, the weight return movement can not occur.The recliner 10 that adjustable bed surface lateral angles is arranged on these sorting bed 4 its bedsteads 25, adjustable discharge baffle plate 9 and adjustable material inlet 5 are equipped with in its bed surface top, by regulating the height of material inlet 5, discharge baffle plate 9, make the material gravity segregation on the bed surface, discharge according to the order of sequence to heavy by light with the proportion difference.Be provided with a plurality of air compartments 18 that link into an integrated entity with it below this sorting bed 4, air compartment 18 connects by flexible pipe 12 with air intake tube 21, air intake tube 21 and air compartment 18 all are equipped with regulates air quantity device 20, the air intake mode can be continuously or the pulsation air feed, but, reach best effect according to material properties flexible modulation air quantity.Air intake tube 21 is provided with slag tap lock 14 and artificial hole 13, and the material less than sieve aperture that drains under sorting bed 4 bed surfaces is arranged, and enters air compartment 18 to air intake tube 21, can in time clear up.The vibration damping adjusting device 6 of hanging in the present embodiment is two covers, is made of steel wire rope 17, regulating wheel 16, rubber spring 19, worm gear 7 respectively, and worm gear 7 is used to regulate vertical angle of sorting bed 4 bed surfaces, and rubber spring 19 slow shaking prolong the life-span of equipment.

Vibrator 1 is that two synchronous band differential oscillators that connect by flexible coupling 28 are formed, and is installed in vertical bottom of gear frame 3, adds buffer spring 15 on its regulating wheel.Be provided with the frequency modulator of translator 24 in the vibrator 1, the vibration force direction of vibrator 1 becomes 21-29 degree angle with sorting bed 4 bed surfaces.

Differential synchronous band vibrator in the present embodiment is by the two-sided synchronous cog belt of a polyurethane (or adhesive tape), with be installed in four axles on gear ratio be the transmission device 22 that 2 gear is meshed and forms, drive the eccentric block that is installed in four Different Weight on four axles respectively with variable-frequency motor 24, make and advance different and produce differential with the speed that retreats, accelerated material handling speed, disposal ability strengthens, low, the stable drive of noise, and the buffer spring 15 that installs additional on regulating wheel can alleviate synchronous band impulsive force.

Operation principle: material enters sorting bed 4 by material inlet 5; Effect leeward at air blast enters air intake tube 21, sieve lower air chamber 18, arrives material bed by sieve plate 26; Material on sorting bed 4 bed surfaces produces inertia force under the effect of vibrator 1, under the effect of inertia force and wind-force, material has carried out layering gradually like this, and the material movement of light specific gravity is to the bed the superiors, and heavy material is deposited to bed lower floor.Under the effect of bed surface cross dip, the material gravitate, the material that proportion is lighter enters second separate slot, the bigger material of proportion is towards the spoil end motion, material in second separate slot is under the effect of inertia and wind-force, directly enter the cleaned coal section and enter the cleaned coal groove 23 that connects material, and the heavier material of proportion again repeated multiple times carry out layering by different levels, the spoil of coal and proportion maximum separately in handle, in coal enter in the coal groove 29 that connects material, heavy spoil enters the spoil groove 11 that connects material from tailstock under the differential action of vibrator 1.The dust of assorting room enters atmosphere with air-introduced machine by dust excluding hood 8.

Above process mainly by the stroke of differential oscillator 1, jig frequency size, feed what, the height of discharge baffle plate 9, the compartmented of the groove that connects material, the size of intake, air intake mode be continuously or pulsation, bed surface portraitlandscape angle regulator wait and realize.
