The purpose of this utility model is for the deficiency that solves the problems of the technologies described above, and a kind of circular shale shaker is provided, and it is simple in structure, and amplitude is big, the frequency height, and operating efficiency can improve more than 50%.
The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: a kind of circular shale shaker, form by transmission gear for electric motor, vibrating mechanism, screen box, bearing and damping, screen box is arranged on the bearing by damping, described vibrating mechanism is formed by the interconnective main shaft of synchronized by two, two main shafts are connected with each self-corresponding transmission gear for electric motor respectively, described main shaft is an eccentric shaft, also be provided with eccentric block on main shaft, screen box is arranged on the main shaft by eccentric block.
Described transmission gear for electric motor is made of driving-belt, motor, panel and base, and panel is arranged on the base by connecting axle, and the motor that is provided with on the panel is connected with main shaft by driving-belt, also is provided with damping spring between panel and base.
Described damping is a spring, also can adopt other elastic parts.
The beneficial effects of the utility model are:
1, the utility model, because the vibrating mechanism that is adopted is two main axle structures, band rotation synchronously synchronously, simple in structure, dependable performance, easy maintenance has enough vibration forces, and amplitude is big, the frequency height is guaranteeing big output, high efficiency while, has alleviated the weight of equipment greatly.
2, this vibratory sieve treating capacity is big, the efficient height, and operating efficiency can improve more than 50%.

The specific embodiment
The utility model, its concrete embodiment is:
As depicted in figs. 1 and 2, a kind of circular shale shaker is made up of transmission gear for electric motor 1, screen box 3, bearing 5, damping 4 and vibrating mechanism 2.Bearing 5 closely contacts by the side plate of damping 4 with screen box 3, and damping 4 described herein can adopt elastic parts such as spring.Screen box 3 is arranged on the vibrating mechanism 2, vibrating mechanism 2 links to each other with transmission gear for electric motor 1, transmission gear for electric motor 1 can pass to kinetic energy vibrating mechanism 2, vibrating mechanism 2 is converted into track with kinetic energy and passes to screen box 3 for the vibration of circle, and the vibration of screen box makes material bed loose on the screen cloth face, and leaves screen cloth and throw, fine fraction can be discharged by bed of material whereabouts and by sieve aperture, and the material grain that will be stuck in the sieve screen apertures kind shakes, and except that sieving actoion, and material travelled forward.
As shown in Figure 3, described transmission gear for electric motor 1 is made of driving-belt 7, motor 6, panel 8 and base 9, give vibrating mechanism 2 by driving-belt 7 with transmission of power by motor 6, motor 6 is installed on the panel 8, panel 8 links to each other with base 9 by connecting axle, damping spring 10 is installed below the panel 8, and damping spring 10 is arranged on connecting axle the right, promptly connects a side of vibrating mechanism 2.After installing driving-belt, driving-belt tension motor, the driven by motor panel compresses damping spring 10 again, can remain the tensile force of driving-belt, effectively prevents to start, stops or taking off band during than large amplitude.
As shown in Figure 4, with the main shaft 11 of transmission of power to vibrating mechanism 2, described vibrating mechanism 2 is two main axle structures to motor 6, forms by synchronized 13 interconnective main shafts 11 by two by driving-belt 7.Two main shafts 11 be arranged in parallel, the identical end of each main shaft is connected with transmission gear for electric motor independently respectively, it is synchronized with the movement 11 connections of two main shafts at its other end by synchronized 13, main shaft 11 is an eccentric shaft, be equipped with two eccentric blocks 12 on each main shaft 11, screen box 3 is arranged on two main shafts 11 by four eccentric blocks 12.Vibrating mechanism 2 makes screen box do the vibration of track for circle by the rotation generation exciting force of its eccentric block and eccentric shaft structure, described synchronized 13 can adopt the combination of synchronous band and synchronizing wheel, because vibrating mechanism is two main axle structures, band rotation synchronously synchronously, simple in structure, dependable performance, easy maintenance, enough vibration forces are arranged, and amplitude is big, the frequency height, guaranteeing big output, high efficiency while, having alleviated the weight of equipment greatly, provided cost savings, is a kind of high-efficiency and energy-saving type, practical, large-scale circular shale shaker.
