Description
Technical field
The present invention relates to vibrating machine technical field, particularly relate in mining machinery the vibrator assembly being applied to vibratory sieve or feeding machine two kinds of equipment, is more particularly a kind of Uniaxial elliptic motion trail vibration exciter.
Background technology
In the middle of disintegrating machine industry, vibratory sieve or these two kinds of equipment of feeding machine adopt single shaft to be most typical structure as vibrator, are also most widely used machines.
The movement locus that one-eccentric rotor type vibrator produces is circumference, and namely circular motion track has normal orientation to vibrate component, and have again tangential direction to vibrate component, such advantage is critical material not easily plug-hole on screen cloth.But just change former movement locus after the spring movement of this circular motion in vibration casing is combined, direct consequence is that material only has and sieves motion up and down, and does not have horizontal transporting movement (horizontal component is atomic).So, on market all use one-eccentric rotor type vibrators equipment in vibrate casing stereotyped all need tilting so that utilize gravity produce horizontal transporting movement.Also just because of tilting reason, material falls hurriedly, sieves insufficient, and screening effect is also undesirable.
For this situation, people have devised again three axle vibrators, the movement locus that three axle vibrators produce is oval, vibrating direction angle can be regulated by the eccentric phase angle changing three axles, the existing screening campaign vertically of material is made to have again the conveying campaign of horizontal direction, and not easily putty, so when employing three axle vibrator after vibration casing just can horizontal positioned use.But three axle exciter structures are very complicated, and cost is very high, use, maintenance all inconvenient (three axle vibrators need be opened vibrator dismounting gear ring when adjusting vibrating direction angle and realize, extremely inconvenient, by user from Row sum-equal matrix time very easily make mistakes).
The equipment of one-eccentric rotor type vibrator is configured under prior art, wherein vibrate casing stereotyped all need tilting, the present invention still uses one-eccentric rotor type vibrator, but can realize the vibration casing horizontal that three axle vibrators could realize arranges feature, and this is remarkable result of the present invention.
Use orbit determination bar and sliding sleeve design, the circular motion track of one-eccentric rotor type vibrator being become elliptical trajectory, improves exciting effect and efficiency, is core technology of the present invention.
Orbit determination mechanism is driven by the inertia force of vibrating shaft, on the one hand with its lower fulcrum for the center of circle, with its lower fulcrum supreme fulcrum length for radius does a bit of oscillating motion (because camber line is very short, be approximately straight line, the natural resiliency of concrete amplitude and exciting vibration spring is closely bound up); Orbit determination bar does stretching motion (amplitude of stretching motion is also closely bound up with the natural resiliency of exciting vibration spring) relative to sliding sleeve on the other hand.The above-mentioned movement limit circular motion track of former one-eccentric rotor type vibrator, become circular motion track into elliptical trajectory (above-mentioned arc pendulum and stretching motion define the long and short axle of elliptical trajectory), what be similar to three axle vibrators generations is elliptical trajectory, as long as just can regulate vibrating direction angle by the magnitude of inclination changing orbit determination bar.So eliminate material under original circular motion track to only have and sieve motion up and down, and there is no the defect of horizontal transporting movement, make the existing screening campaign vertically of material have again the conveying campaign of horizontal direction.
After adding the servicing units such as above-mentioned tilting orbit determination bar, vibrate casing in the equipment of one-eccentric rotor type vibrator and change machine-made tilting, realize horizontal positioned and use.Simultaneously also just because of the structure of horizontal, make material screening more abundant, screening effect is more desirable.
Beneficial effect: (1) structure is simple, easy to manufacture; (2) operation and maintenance is convenient, especially regulates vibrating direction angle; (3) easy to the transformation of old product, and be easy to realize.
As preferably, described orbit determination bar is all arranged perpendicular to the fixing axial line of vibrating shaft.
The circular motion track of former one-eccentric rotor type vibrator moves in the plane at its vibrating shaft end face, if not on that plane, the consequence brought is unstable, micro-shaking, even kill motionless, the fixing axial line of orbit determination bar perpendicular to vibrating shaft is arranged, by the movement definition on orbit determination bar on this plane, the movement locus of synthesis is more stable, desirable.
As preferably, the jointed shaft of described orbit determination bar and base is arranged in the arc adjuster on base, and arc adjuster comprises the arc-shaped slot on pedestal and pedestal, and described jointed shaft to be arranged in arc-shaped slot and to be locked by adjusting nut.The angle angular range of described orbit determination bar and horizontal plane is spent 30 to 60.
This acute angle is vibrating direction angle, and deflection is determined by the angle of inclination of orbit determination mechanism, so the tilt adjustment of conveniently orbit determination mechanism, arranges arc adjuster.Can adjust between 0-90 ° in theory, within the scope of 30 ° ~ 60 °, usually be adjusted to best.
As preferably, when above-mentioned orbit determination mechanism is odd number pair, the sliding sleeve being arranged in the orbit determination mechanism that the orbit determination mechanism on vibration casing the same side mediates is arranged on vibrating shaft with the jointed shaft of vibration casing and fixes on the vertical line at place, axle center, and the vertical line that place, axle center is fixed with vibrating shaft by other orbit determination mechanism is arranged symmetrically with.
Orbit determination mechanism is arranged in pairs, and be the both sides being arranged in vibration casing symmetrically, be specifically the end positions being positioned at vibrating shaft vibrating bin body side surface on, and again will be positioned at vibration casing the same side on orbit determination mechanism equilibrium arrange, further increase vibration balancing.
As preferably, when above-mentioned orbit determination mechanism is even-even, is positioned at the vertical line that the orbit determination mechanism on vibration casing the same side fixes place, axle center with vibrating shaft and is arranged symmetrically with.
Orbit determination mechanism does not put in pairs, and be the both sides being arranged in vibration casing symmetrically, be specifically the end positions being positioned at vibrating shaft vibrating bin body side surface on, and again will be positioned at vibration casing the same side on orbit determination mechanism equilibrium arrange, further increase vibration balancing.
