Description
Technical field
The utility model relates to the vibrating machine technical field, relates in particular to the vibrator assembly that is applied to vibratory sieve or two kinds of equipment of feeding machine in the mining machinery, a kind of single shaft straight-line trajectory vibrator of more specifically saying so.
Background technology
These two kinds of equipment employing single shafts of vibratory sieve or feeding machine are most typical structures as vibrator in the middle of the disintegrating machine industry, also are most widely used machines.
The movement locus that one-eccentric rotor type vibrator produces is a circumference, and the existing normal orientation vibration of circular motion track component has tangential direction vibration component again, and such advantage is that critical material is difficult for plug-hole on screen cloth.But this circular motion with just change former movement locus after the spring motion of vibration in the casing combines, directly consequence is that material has only screening motion up and down, and does not have horizontal feed move (horizontal component is atomic).So all use in the equipment of one-eccentric rotor type vibrators that the vibration casing is stereotyped all to be needed tiltingly on the market, produce horizontal feed so that utilize gravity and move.Just because of tilting reason, material falls hurriedly, sieves insufficiently, and screening effect is also undesirable.
To this situation; People have designed a kind of twin shaft vibrator again; The movement locus that the twin shaft vibrator produces is a straight line; As long as vibrating direction angle just can be regulated in the eccentric phase angle through changing twin shaft, make the existing screening campaign vertically of material that the conveying campaign of horizontal direction arranged again, so when adopting twin shaft vibrator after vibration casing just can horizontal positioned to use.It has been no small number just that the cost light of a right vibrating shaft is calculated volume weight, in addition is that a twin shaft exciting assembly is set.Moreover, need open vibrator during twin shaft vibrator adjustment deflection and the dismounting gear ring is realized, extremely inconvenient, very easily make mistakes when adjusting voluntarily by the user.
The utility model content
It is not enough that the purpose of the utility model is to overcome above-mentioned existing in prior technology, provide a kind of simple in structure, be easy to realize, cheap single shaft straight-line trajectory vibrator.
In order to reach above purpose, the utility model is realized through following technical scheme: a kind of single shaft straight-line trajectory vibrator, involving vibrations casing, base, exciting vibration spring and vibrating shaft, vibrating shaft are arranged on the vibration casing; Exciting vibration spring is arranged between vibration casing and the base; It is characterized in that described vibration casing is provided with orbit determination bar more than two pairs, every pair of orbit determination pole pair is claimed to be arranged on the vibration casing both sides; The upper end of said orbit determination bar is hinged on the vibration casing, and the lower end is hinged on the base, the unified oblique and one-tenth arranged in arrays of said orbit determination bar.
The architectural feature of the utility model is: (1) still adopts single shaft as exciting source; (2) have additional the orbit determination bar of making the arc pendular motion (can change former one-eccentric rotor type vibrator movement locus) of oblique layout; (3) the vibration casing need not tiltingly, can be horizontally disposed with use.
The equipment of configuration one-eccentric rotor type vibrator under the prior art; Wherein vibrate casing stereotyped all need tilting; The utility model is still used one-eccentric rotor type vibrator, but can realize that the vibration casing horizontal that the twin shaft vibrator could be realized is provided with characteristics, and this is the remarkable result of the utility model.
The design of utilization orbit determination bar becomes straight-line trajectory with the circular motion track of one-eccentric rotor type vibrator, has promoted exciting efficiency; Be the core technology of the utility model: it is the center of circle with its lower fulcrum that the inertia force of vibrating shaft drives the orbit determination bar; With the supreme fulcrum length of its lower fulcrum is that radius is done a bit of oscillating motion (very short because of camber line, be approximately straight line, self elasticity of concrete amplitude and exciting vibration spring is closely bound up); This motion has limited the circular motion track of former one-eccentric rotor type vibrator; Become the circular motion track and be straight-line trajectory, be similar to the straight-line trajectory that the twin shaft vibrator produces, as long as just can regulate vibrating direction angle through the magnitude of inclination that changes the orbit determination bar.So, eliminated that material under original circular motion track has only screening motion up and down and the defective that do not have the horizontal feed motion makes the existing screening campaign vertically of material that the conveying campaign of horizontal direction arranged again.
After having increased above-mentioned tilting servicing units such as orbit determination bar, the vibration casing is changed machine-made tiltingly in the equipment of one-eccentric rotor type vibrator, realizes that horizontal positioned uses, and makes material screening more abundant, and screening effect is desirable more.
Beneficial effect: (1) is simple in structure, easy to manufacture; (2) operation and maintenance is convenient, especially regulates vibrating direction angle; (3) transformation to old product is easy, and is easy to realize.
As preferably, said orbit determination bar is all perpendicular to the fixedly axial line setting of vibrating shaft.
The circular motion track of former one-eccentric rotor type vibrator is on plane, vibrating shaft end face place, to move; If not on this plane; The consequence of bringing is unstable, little shaking, in addition kill motionless, so the orbit determination bar is arranged perpendicular to the fixedly axial line of vibrating shaft; On this plane, synthetic movement locus is stable, desirable more with the movement definition on the orbit determination bar.
As preferably, the jointed shaft of said orbit determination bar and base is arranged on the arc adjuster on the base, and arc adjuster comprises the arc-shaped slot on pedestal and the pedestal, and said jointed shaft is arranged in the arc-shaped slot and by adjusting nut and locks; The angle angular range of said orbit determination bar and horizontal plane is at 30 to 60 degree.
This angle is vibrating direction angle, and deflection is by the decision of the angle of inclination of orbit determination bar, so the tilt adjustment of orbit determination bar for ease is provided with arc adjuster.Can between 0-90 °, adjust in theory, in 30 °～60 ° scopes, be adjusted into the best usually.
As preferably; Above-mentioned orbit determination bar be odd number to the time; Be arranged in hinged place, orbit determination bar upper end that the orbit determination bar on vibration casing the same side mediates and be arranged on vibrating shaft fixedly on the vertical line at place, axle center, other orbit determination bar is with the fixing vertical line symmetric arrangement that belongs to of axle center of vibrating shaft.
The orbit determination bar is provided with in pairs, and is the both sides that are arranged in the vibration casing symmetrically, is to be positioned on the vibrating bin body side surface of end positions of vibrating shaft specifically, and will be positioned at balanced layout of orbit determination bar on vibration casing the same side again, further increases vibration balancing property.
As preferably, when above-mentioned orbit determination bar is even-even, be positioned at orbit determination bar on vibration casing the same side with the fixing vertical line symmetric arrangement that belongs to of axle center of vibrating shaft.
The orbit determination bar is provided with in pairs, and is the both sides that are arranged in the vibration casing symmetrically, is to be positioned on the vibrating bin body side surface of end positions of vibrating shaft specifically, and will be positioned at balanced layout of orbit determination bar on vibration casing the same side again, further increases vibration balancing property.
