The specific embodiment

Below in conjunction with accompanying drawing and example, the utility model is described in further detail:

As shown in Figures 1 to 5, a kind of buffering gravity flow vibratory sieve of the present embodiment, comprise: vibratory sieve main body 3, main screen support 4, foreign material chute 5 and buffering screen cloth support 7, one vibrating motor 1 is respectively installed in the left and right sides of described vibratory sieve main body 3, described vibratory sieve main body 3 tops, bottom and rear aperture, its lap is sealing surface; Described main screen support 4 and buffering screen cloth support 7 and be all installed in the inner chamber of vibratory sieve main body 3 and buffering screen cloth supports 7 and is positioned at main screen and supports 4 top, the length of described main screen support 4 is greater than buffering screen cloth and supports 7 length, described main screen supports 4 and supports on 7 and be provided with screen cloth with buffering screen cloth, four jiaos of places of described vibratory sieve main body 3 are respectively provided with a rubber spring 2, one end of described rubber spring 2 is connected with vibratory sieve main body 3, and the other end is connected with fixing base; Described foreign material chute 5 is fixed in the rear aperture place of vibratory sieve main body 3, the end face of described foreign material chute 5 is inclined-plane, it is horizontal positioned that main screen supports 4, thereby the direction of vibration of vibrating motor 1 and main screen support the vertical direction of 4 screen cloth faces be a less angle be convenient to material on main screen to rear flow, material is fallen on main screen after dropping on buffering screen cloth, under the vibration of vibrating motor 1, flow backward, in flow process, the lower thing of filter sees through screen cloth toward dirty, and the foreign material on screen cloth flow to the rear discharge of foreign material chute 5 backward.

Preferably, in described vibratory sieve main body 3 inner chambers, be connected with the reinforcement 6 arranging along vibratory sieve main body 3 widths, so can prevent that vibratory sieve main body 3 is out of shape in vibration processes.

Preferably, described reinforcement 6 is two rows altogether, so can make vibratory sieve main body 3 stressed more even in vibration processes.
