Further, said top board B detachably is provided with through hold-down nut, hold-down bolt, stop nut, and said hold-down nut is fixedly set on the backboard, stop nut is set on the said hold-down bolt and cooperates with hold-down nut.
Further, the corresponding hold-down bolt of said top board B is fixed with limiting gasket.
Further, said grating seat is provided with the grating hole, and the diameter in this grating hole is between the diameter at said grating two ends, this grating hole and grating movingly, the larger diameter end of said grating is spacing by backboard.The two ends diameter that is grating is different, and the smaller diameter end of grating is inserted the grating seat, and larger diameter end is spacing to it by backboard, stops grating to withdraw from.So, during the screening machine vibration, thereby grating can rotate the contact-making surface of conversion and material in the grating hole, play self-cleaning function.
Further, said grating seat is elastic wear-resisting cast polyurethane forms.
Further, said vibratory sieve compass screen surface is to be that the unit is put together by some above-mentioned compass screen surfaces.
The utlity model has following advantage:
1. the grating support of the utility model is the semi-surrounding groove of middle demountable structure, and being used to hold can crooked grating seat, so that the grating seat is extracted out or inserted when changing.When changing the grating seat, the top board B in the middle of pulling down, the grating seat can be extracted replacing out.
2. the grating of the utility model is designed to cantilever beam structures, can increase the free vibration amplitude of grating like this, reduces the adhesion of wet adhesive material.
3. the utility model grating seat can adopt and have elasticity and wear-resisting like cast polyurethane, and grating is installed in the grating seat movingly.
4. the utility model top board B detachably is provided with through hold-down nut, hold-down bolt, stop nut, and is special, is provided with limiting gasket in the fixed-site of the corresponding hold-down bolt of top board B, be used for hold-down bolt spacing so that better fixing top board B.
5. the utility model grating support can be made the monoblock compass screen surface that directly links to each other with screen frame, also can make several little compass screen surface unit and be spliced into whole compass screen surface.
