Description
Technical field
The utility model relates to a kind of coal washing screening plant of solid separation equipment technical field, specifically a kind of actuating unit device of mechanical movable-sieve jig.
Background technology
Movable-sieve jig is that a kind of direct outer power driving sieve nest moves up and down in aqueous medium, causes material periodically loose, realizes the screening installation by density stratification, is widely used in the ideal equipment of piece raw coal discharge refuse and steam coal separation.Movable-sieve jig divides fluid pressure type to drive and mechanical type drives two kinds, the present mechanical type movable-sieve jig that uses, driving force is provided by mechanical component, it is simple to have attended operation, reliable, cost is low, advantage easy to maintenance, receive praises from customers, but the actuating unit of driving sieve nest all adopts monolateral type of drive, the discontinuity that this type of drive produced, thereby cause power transmission shaft and rod deformation, problems such as moving sieve nest polarization, have a strong impact on actuating unit intensity and reliability, increased the maintenance cost of equipment, also influenced the separating effect of movable-sieve jig simultaneously.
Summary of the invention
Goal of the invention of the present utility model is to overcome the discontinuity that actuating unit produced of the monolateral driving sieve nest of prior art, cause defectives such as power transmission shaft and rod deformation, moving sieve nest polarization, and provide the actuating unit of the bilateral driving sieve nest of a kind of usefulness to drive the actuating unit device of the mechanical movable-sieve jig of sieve nest running.This device utilizes the crank mechanism of symmetry to strengthen driving the stress equalization of sieve nest, effectively solve the motor-driven sieve nest of existing machinery formula vibro-assisted jigging and dragged the unbalance stress perseverance, cause moving sieve nest polarization, actuating unit intensity to reduce, safeguard the problem of frequent and separating effect difference.
The utility model solves the problems of the technologies described above by the following technical solutions: a kind of actuating unit device that is used for mechanical movable-sieve jig, comprise mainly by motor, belt pulley, final drive shaft, eccentric wheel, camshaft; the bilateral driving actuating unit that rocker arm shaft and rocking arm are formed; moving sieve nest; described motor is connected with belt pulley; belt pulley is connected with final drive shaft; final drive shaft is connected with camshaft; camshaft and rocker arm shaft are in transmission connection; described eccentric wheel; rocking arm all is set to two; two eccentric wheels are identical and match the same two ends that place camshaft; two rocking arms are identical and be symmetrically placed on the rocker arm shaft; two eccentric wheels are connected with connector with two rocking arms successively, and the other end of rocking arm is connected with connector with moving sieve nest respectively.
Adopt technique scheme, compared with prior art, the utility model improves at the problem of existing machinery formula movable-sieve jig reliability etc. and improves, adopted the actuating unit of double-crank mechanism as moving screen device, its significant advantage is: 1. Zhuan Zhi actuating unit is under the effect of bilateral transmission, moving sieve nest vibration stress equalization has reduced because moving sieve nest polarization to the excessive wear of bearing etc., has prolonged the service life of bearing.2. owing to move the minimizing of sieve nest polarization, the efficiency of separation and effect also are improved.3. parts such as the eccentric wheel that increases in the bilateral driving actuating unit, rocking arm, not only shaking has added the stability of dynamical system, has also strengthened the intensity and the reliability of actuating unit simultaneously.4. simple in structure, easy to operate, the operation troubles rate reduces, and compares with the moving screen device of the hydraulic pressure of same treatment ability to have tangible price advantage.Based on above-mentioned advantage, the upgrading and the transformation of the utility model particularly suitable existing machinery movable-sieve jig have broad application prospects.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Present embodiment is a kind of actuating unit device that is used for mechanical movable-sieve jig, and its design philosophy is that prior art is improved, and improved core is: set up an eccentric wheel, set up a rocking arm, realize bilateral driving sieve nest.
Referring to Fig. 1, the utility model actuating unit device is a mechanical device.Form by bilateral driving actuating unit, moving sieve nest 2, lifting wheel 5, gear pair 9 etc.Bilateral driving actuating unit transmits with moving sieve nest 2 motions and is connected.Described bilateral driving actuating unit is made up of motor 6, belt pulley 7, final drive shaft 8, two rocking arms 3, two eccentric wheels 4, camshaft 10 and rocker arm shafts 11.Motor 6 is connected with belt pulley 7, and belt pulley 7 is sleeved on the final drive shaft 8, and final drive shaft 8 is connected by gear pair 9 with camshaft 10.Identical and the pairing of described two eccentric wheels 4 places the two ends of camshaft 10 successively, article two, rocking arm 3 identical and symmetrical two ends that place rocker arm shaft 11 successively, two eccentric wheels 4 are connected with two rocking arms, 3 usefulness bearing pins successively, and the other end of rocking arm 3 is connected with moving sieve nest 1 usefulness bearing pin respectively.Bilateral driving actuating unit, moving sieve nest 2, lifting wheel 5, gear pair 9 etc. place on the casing 1.
See Fig. 1-2, the power of motor 6 is delivered to eccentric wheel 4 through transmission components such as belt pulley 7, final drive shaft 8, gear pair 9, camshafts 10, eccentric wheel 4 and rocker arm shaft 11 are connected by bearing pin; rocking arm 3 connects moving sieve nest 2; two eccentric wheels 4 drive two rocking arm 3 front-rear reciprocation movements; and then the moving sieve nest 2 that is connected with two rocking arm 3 other ends is done pump, carry out the jigging sorting.Also promptly the rotating torque by motor 6 finally is delivered to pumping of moving sieve nest 2.
It is as follows that the utility model is used on the mechanical movable-sieve jig its course of work: when movable-sieve jig was worked, moving sieve nest 2 was done upper and lower reciprocating motion around fixed pin shaft under the effect of bilateral driving actuating unit.After feed coal feeds, on moving sieve nest 2, form bed.Rocking arm 3 hauls moving sieve nest 2 and moves upward, and material is held up by whole layer; When the moving sieve nest 2 of rocking arm 3 effects descended downwards fast, the particle of different densities was with the sedimentation in water of different speed.Through moving up and down for several times repeatedly, material is realized by density stratification, and is moved forward with the moving sieve nest 2 that tilts.The light material in upper strata is discharged through different outlets respectively with the lower floor spoil.
