Description
Technical field
The present invention relates to the vibrating machine technical field, relate 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 elliptical trajectory vibrator of more specifically saying so.
Background technology
In the middle of the disintegrating machine industry, it is most typical structure as vibrator that these two kinds of equipment of vibratory sieve or feeding machine adopt single shaft, also is most widely used machine.
The movement locus that one-eccentric rotor type vibrator produces is a circumference, and the circular motion track promptly has normal orientation vibration component, and tangential direction vibration component is arranged 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, move so that utilize gravity to produce horizontal feed.Also just because of tilting reason, material falls hurriedly, sieves insufficiently, and screening effect is also undesirable.
To this situation; People have designed three vibrators again; The movement locus that three vibrators produce is oval, can regulate vibrating direction angle through the eccentric phase angle that changes three, makes the existing screening campaign vertically of material that the conveying campaign of horizontal direction arranged again; And be difficult for putty, so when adopting three vibrator after vibration casings just can horizontal positioned to use.But three exciter structures are very complicated, and cost is very high, use, keep in repair all inconvenient (three vibrators need be opened vibrator dismounting gear ring and realize when the adjustment vibrating direction angle, extremely inconvenient, very easily make mistakes when being adjusted voluntarily by the user).
Summary of the invention
It is not enough to the objective of the invention is to overcome above-mentioned existing in prior technology, provide a kind of simple in structure, be easy to realize, cheap single shaft elliptical trajectory vibrator.
In order to reach above purpose, the present invention realizes through following technical scheme: a kind of single shaft elliptical 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 mechanism more than two pairs, every pair of orbit determination mechanism is arranged symmetrically on the vibration casing both sides; Said orbit determination mechanism comprises an orbit determination bar and a sliding sleeve; The upper end of said orbit determination bar is set in the sliding sleeve, and said sliding sleeve is hinged on the vibration casing, and the lower end of said orbit determination bar is hinged on the base, the unified oblique and one-tenth arranged in arrays of said orbit determination bar.
Architectural feature of the present invention is: (1) still adopts single shaft as exciting source; (2) have additional the orbit determination mechanism that makes the arc pendular motion (form to change former one-eccentric rotor type vibrator movement locus by orbit determination bar and sliding sleeve) 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 present invention still uses one-eccentric rotor type vibrator, but can realize that the vibration casing horizontal that three vibrators could be realized is provided with characteristics, and this is a remarkable result of the present invention.
Utilization orbit determination bar and sliding sleeve design, and the circular motion track of one-eccentric rotor type vibrator is become elliptical trajectory, have promoted exciting effect and efficient, are core technologies of the present invention.
Orbit determination mechanism is driven by the inertia force of vibrating shaft, is the center of circle with its lower fulcrum on the one hand, 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) with the supreme fulcrum length of its lower fulcrum; The orbit determination bar is done stretching motion (amplitude of stretching motion is also closely bound up with self elasticity of exciting vibration spring) with respect to sliding sleeve on the other hand.Above-mentioned motion has limited the circular motion track of former one-eccentric rotor type vibrator; Become the circular motion track and be elliptical trajectory (above-mentioned arc pendulum and stretching motion define the long and short axle of elliptical trajectory); What be similar to three vibrators generations is elliptical trajectory, as long as just can regulate vibrating direction angle through the magnitude of inclination that changes the orbit determination bar.So eliminate under original circular motion track material and had only screening motion up and down, and do not had the defective of horizontal feed motion, made 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.Also just because of the structure of horizontal, make material screening more abundant simultaneously, screening effect is desirable more.
