Abstract
The utility model discloses a two-axis synchronous elliptic vibrating screen which belongs to a vibrating screening machinery field. The utility model is designed aiming at the problem that the existing elliptic vibrating screen which needs three vibrating shafts has a complicated structure. A vibrator is installed on an installation beam of the vibrating screen. Every vibrating shaft on the vibrator is installed with an eccentric block with equal eccentricity weight which is connected by a gear and synchronously operates. The installation positions of the eccentric blocks are characterized in that when the plane where a center line of two vibrating shafts are on is horizontal and the eccentricity direction of the eccentric block on one of the vibrating shafts is vertically downward, an angle between the eccentricity direction of the eccentric block on another vibrating shaft and the first shaft is Alpha and the value of Alpha is more than 0 degree and less than 90 degrees. A motor is connected with one of the vibrating shafts of the vibrator via a connecting shaft and drives the vibrator to operate synchronously and form an elliptic motion trajectory. The utility model has the advantages of simple structure, good generality and convenient adjustment and can be used in material screening operation in metallurgy, mining, transportation and hydropower, etc. departments.
Description
Technical field
The utility model belongs to the vibration screening machinery field, mainly relates to carry out difficult screened material the synchronous elliptically vibrating screen of diaxon of classification.
Background technology
The elliptically vibrating screen of using generally is that three vibrating shafts are arranged at present, is installed on two side plates of screen box.The eccentric block that eccentric weight equates, eccentric arm is identical all is equipped with at the two ends of each on the position of sieve box side plate.Connect by isoparametric gear, force run-in synchronism.It is the synthetic elliptical trajectory vibratory sieve of straight-line trajectory and circular motion track.Because it is high that the complex structure of this vibratory sieve, installation accuracy require, improved the manufacturing cost and the difficulty of vibratory sieve widely, this structure is unfavorable for the large scale development of vibratory sieve simultaneously.
Summary of the invention
The purpose of this utility model provides the synchronous elliptically vibrating screen of a kind of diaxon, and this vibratory sieve can be realized the screening operation of elliptic motion trace effectively, realizes the classification to difficult screened material.
The utility model is realized by following measure.Mainly form by base, isolation mounting, screen box, sieve plate and vibrator.It is characterized in that: the vibrator of vibratory sieve has two vibrating shafts, and an eccentric block is housed on each vibrating shaft, and the eccentric weight of eccentric block equates on two axles, connects run-in synchronism by gear; The installation site of eccentric block is, when two vibrating shaft center line place planar horizontal, the eccentric direction of eccentric block is vertically downward the time on vibrating shaft, and the eccentric direction of eccentric block and first angle are α on another vibrating shaft, and the value of α is greater than 0 degree, less than 90 degree.Motor is connected with a vibrating shaft of vibrator by connecting axle.
In order to adapt to the demand of different material screening, on the side plate of screen box and mounting rail, can be provided with 1-6 vibrator.Motor can be connected with vibrator by synchronized, and described synchronized is made up of a pair of same parameter gear that is meshed, and two output shafts of synchronized are connected with two vibrating shafts of vibrator by connecting axle respectively.According to the needs of screening condition, can directly be connected by connecting axle by two motors respectively with two vibrator shafts, carry out the motor synchronizing running.The isolation mounting of vibratory sieve can be an isolation mounting, also can be the two-stage vibration isolation device.Vibrator and mounting rail can be arranged on screen box below.
When actuating motor makes vibratory sieve when work,, make vibratory sieve carry out screening operation with oval-shaped movement locus because the eccentric block on vibrating shaft has a relative angle with another in the vibrator.Adjust the size of angle α, can change the parameter of elliptical trajectory.
The beneficial effects of the utility model are, adopt the frame mode of the eccentric block relative displacement on two vibrating shafts, have formed the elliptic motion trace of vibratory sieve, and every vibratory sieve can be provided with a plurality of vibrators, can adapt to the large scale development of elliptically vibrating screen fully.Have simple in structure, the characteristics that versatility is good He easy to adjust.Can be applicable to the material screening operation of departments such as metallurgy, mine, traffic and water power.
