Fig. 2 is the cutaway view of the utility model most preferred embodiment.

The specific embodiment

Below in conjunction with accompanying drawing the utility model being done one describes in detail.

As Fig. 1 and Fig. 2 is most preferred embodiment of the present utility model, a kind of granularity screening machine is specifically disclosed, it comprises pedestal 1, screening body 2 and eccentric vibrating device etc., pedestal is made of a hollow base 11 and support bar 12, a motor 4 and a reduction box 5 have been installed in hollow base 11 inside, screening body 2 comprises the upper plate 22 that is all had eccentric bushing 26 by two sieve fixed legs 21 and two two ends, lower shoe 23 constitutes a firm framework, screen tray 24 and the emery disc frame 25 that is used for supporting several stack screen traies that several stacks are arranged between two sieve fixed legs 21, framework is arranged between the support bar 12, the eccentric bushing 26 at its upper plate 22 two ends is installed in the top of support bar 12, eccentric vibrating device comprises a rotating shaft 31, one fixed axis 32, one rotating disk 33 and be fixed on the eccentric block that has eccentric circular hole 35 34 on the rotating disk 33, rotating disk 33, eccentric block 34 all is arranged on the inside of base 11, drive by the reduction box 5 that is connected with motor 4, rotating shaft 31 and fixed axis 32 pass support bar 12 and are entrenched in 26 li of eccentric bushings and form with screening body 2 and firmly be connected, on the bedplate of base 11, also be provided with the circular hole 13 of a diameter greater than the diameter of rotating shaft 31 with rotating shaft 31 terminal corresponding positions, the eccentric circular hole 35 that the end of rotating shaft 31 passes circular hole 13 and eccentric block 34 matches, also be provided with one in support bar 12 1 sides and strike vibrating device 6, it comprises motion bar 61, one end is fixed on the tortuous connecting rod 62 of support bar 12, an oscillator 63 that is connected with tortuous connecting rod 62 other ends and a skewback 64 of on described rotating disk 33, setting up, 65 a ridge 7 that shake of oscillator 63 facing to upper plate 22 centres, bedplate and skewback 64 that motion bar 61 ends pass base 11 coincide, the top contact oscillator of motion bar 61.

The operation principle of the utility model most preferred embodiment: when the granularity screening machine carries out screening operation, start power supply, motor 4 drives reduction box 5 work, reduction box 5 drives rotating disk 33 and rotates, and the work that also rotates of the eccentric block 34 that is fixed on rotating disk 33 and skewback 64, the rotating shaft 31 that coincide with the eccentric circular hole 35 of eccentric block 34 is driven does eccentric the vibration, also drive the screening body simultaneously and do eccentric vibration, it is promptly identical once with the end of motion bar 61 that skewback 64 rotates a week, and the top of motion bar 61 just supports to certain altitude to oscillator 63, and when the end of skewback 64 and motion bar separates, oscillator 63 loses support free-falling downwards again, 65 ridge (7) that beat in the middle of the upper plate (22) of screening body that shake of oscillator 63.

Adopt most preferred embodiment of the present utility model, work by the motor drives reduction box, both can drive the screening body and do eccentric vibration, and can drive the oscillator that strikes the mechanism of shaking again and strike the screening body that shakes, easy and simple to handle and high efficiency toward downward direction, because the amplitude of screening body vibration is big, the product of screening different size is more thorough, and screens body in vibration, and oscillator constantly strikes the screening body that shakes downwards, can avoid the screen tray mesh to stop up, the sandstone that filters out different size is more accurate.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
