The specific embodiment

The invention will be further described below in conjunction with accompanying drawing

In Fig. 1～6, a kind of arch breaking screw conveyor mainly comprises reducing motor 1, broken arch axis 6, broken arch splash bar 8, main shaft 9, casing 12, right-handed screw blade 14, antispin blade 15, arch sheet 10 etc.The reducing motor 1 that is installed on the motor cabinet 16 links to each other with main shaft 9 one ends by coupler 2, and the drive sprocket 3 on main shaft 9 axle heads is formed chain-driving by chain 4 and the driven sprocket 5 on broken arch axis 6 axle heads; Right-handed screw blade 14 and antispin blade 15 all are welded on the main shaft 9 forms conveyor screw, and is fixed on the casing 12 by the rolling bearing units 22 at two ends; Fixed several broken arch splash bars 8 on the broken arch axis 6, broken arch axis 6 is fixed on the casing 12 by the rolling bearing units 22 at two ends; The sealing structure of shaft end of broken arch axis 6, main shaft 9 is identical, with four stay tubes 20 from a distance, is used for installing shaft end seal between rolling bearing units 22 and casing 12 end plates, passes stay tube 20 with rolling bearing units 22 fixedly on casing 12 end plates with overbolt 18 again; Seal receptacle 19 is welded on casing 12 end plates, and gland packing 17 is packed in the seal receptacle 19, with in the gland cover 23 indentation sealing seats 19 and pinch-off seal fillers 17, with bolt gland cover 23 is fixed on the seal receptacle 19 again.At the inlet point place with bolt with arch sheet 10 fixedly on the casing 12.

Reducing motor 1 links to each other with drive sprocket 3, drive sprocket 3 drives driven sprocket 5 work by chain 4 again, when reducing motor 1 work, driven sprocket 5 runnings drive broken arch axis 6 rotations, broken arch splash bar 8 on the broken arch axis 6 is and then rotation also, the material of being come in by inlet point 7 is breaking under the stirring of encircleing splash bar 8, just can be at inlet point 7 place's putties, simultaneously, drive sprocket 3 drives conveyor screw 9 rotations, and the material that inlet point 7 places are fallen transports backward, for limited flow, guarantee coefficient of fullness, below that the most forward piece maintenance cover plate 11, added an arch sheet 10, so just can effectively prevent putty, material is by the promotion of conveyor screw 9, transportation forward in casing 12,13 places fall up to discharging opening, enter other equipment.Bearing of the present invention is to adopt hanging structure to install, the bearing that comprises brokenly arch axis 6 and conveyor screw 9, gland packing 14 is housed between bearing and casing, gland cover 21 is compressed and be fixed on the seal receptacle 16 with bolt 18, so just can avoid contacting of bearing and material, can increase the service life, then rolling bearing units 19 usefulness bolts 15 are connected with casing 12 by stay tube 17, fix conveyor screw 9, the bearing portions of broken arch axis 6 is also so installed, the afterbody of conveyor screw 9 has square toes 20, is that manually rotating screw body 9 comes inspection and maintenance when the present invention causes putty owing to fault.
