Abstract
The utility model relates to a vibrating screen for sifting materials, in particular to a large-area vibrating screen used in mineral concentration, coal preparation and the like. The utility model comprises a screen box, an exciter and a machine base, wherein the screen box is supported on the machine base by a vibration isolation spring, the exciter employs four or over four even exciting motors which are symmetrically mounted in appropriate positions on both sides of the screen box, each exciting motor has same eccentric quality, all the exciting motors on the same side co-rotate with constant-speed, two groups of exciting motors on both sides counter-rotate with constant-speed, an included angle between the mounting position of two groups of motors or the exciting motors and a side board of the screen box can be changed, and then the exciting forces produced can cause the screen box to achieve the translational ellipse, variable-ellipse, straight line, and variable linear motion. The vibrating screen employs a plurality of standardized exciting motors, has the advantages of simple structure, convenient installment and low costs, thereby being capable of satisfying requirements of the large-area vibrating screen for the exciting force, and greatly improving screening efficiency, handling capacity, and transport speed of the materials.
Description
Technical field
The utility model relates to the vibratory sieve of material screening, particularly the large tracts of land vibratory sieve that uses in the operation such as ore dressing, coal separation.
Background technology
Domestic and international employed vibratory sieve also is made up of screen box, vibrator and base usually at present, and two eccentric shafts that vibrator comprises have adopted gear, synchronous band etc. to force Synchronous Transmission, or adopt two shock electric machine motor synchronizings to realize exciting.But owing to only adopted two eccentric shafts, the exciting force that produces is not enough to satisfy the demand of the vibratory sieve of big cover surface to exciting force, therefore a kind of multiaxis motor synchronizing balanced elliptical shale shaker has been proposed in patent 00259925.2, can adopt three and above eccentric shaft, every by a motor-driven, this mechanism is if directly adopt the mounting means of shock electric machine across the screen box biside plate, and then the structure to present shock electric machine has proposed new requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of many shock electric machines motor synchronizing balanced elliptic, linear vibrating screen, this vibratory sieve can adopt normalized a plurality of shock electric machines to produce big exciting force to realize the requirement of large tracts of land vibratory sieve to exciting force, simultaneously simple in structure, with low cost.
For achieving the above object, the utility model is taked following technical scheme.
A kind of many shock electric machines motor synchronizing balanced elliptic, linear vibrating screen, mainly by screen box, vibrator and base are formed, screen box is bearing on the base by isolation spring, it is characterized in that, described vibrator adopts four or more even number shock electric machine to be installed in the appropriate location of screen box both sides symmetrically, each shock electric machine has identical eccentric mass, the constant speed revolution in the same way of all shock electric machines of the same side, two groups of shock electric machine constant speed reversed turnings of both sides, change the installation site of two groups of motors, the exciting force of its generation can make screen box realize balanced elliptic, become oval, straight line, become rectilinear motion.
By the shock electric machine in the change vibrator and the angle of sieve box side plate, can obtain the different elliptic motion of ovality, become elliptic motion, rectilinear motion, the straight-line vibratory sieve of change, to satisfy the requirement of different screening operations.
Compared with prior art, advantage of the present utility model is: (1) is compared with the self-synchronizing vibrating screen of the bi-motor exciting of present use, bigger exciting force can be provided, the transport velocity of screening efficiency, treating capacity and material is improved greatly; (2) adopt a plurality of motor symmetries to be installed on the side plate of screen box, make the stressed reasonable of screen box, intensity and life-span are improved; (3) adopt standardized shock electric machine, simple in structure, easy for installation, with low cost, can realize that the nothing of vibratory sieve is safeguarded running.
