For reaching above-mentioned purpose, this utility model be the technical scheme is that a kind of spiral coal conveyor of offer, manages including delivering coal of hollow and is arranged on the auger of delivering coal delivering coal in pipe；Auger of delivering coal includes helical axis, the helical blade being arranged on helical axis and is installed on the shaft coupling head of helical axis end, and shaft coupling head is connected with being positioned at the reductor outside pipe of delivering coal；
Delivering coal and be arranged with a windband pipe on pipe, windband pipe is provided with wind-distributing pipe, and wind-distributing pipe extends to deliver coal in pipe, pipe of delivering coal is additionally provided with by coal bunker, and pipe of delivering coal is provided with discharging opening away from the end by coal bunker.
Preferably, one end of windband pipe blocks with pipe outer wall of delivering coal and welds, and the other end is provided with the thermal insulation board of horseshoe type.
Preferably, shaft coupling head is connected with reductor by coupling band.
Preferably, the back-up ring for bolt location it is provided with between shaft coupling head and coupling band.
Preferably, helical blade is welded on helical axis.
Preferably, helical blade is coated with nickel tungsten scuff-resistant coating.
In sum, this utility model has the advantage that
1, this utility model is by sheathed windband pipe on pipe of delivering coal, and on windband pipe, it is provided with the wind-distributing pipe extending to deliver coal in pipe, when fire coal carries through auger of delivering coal in pipe of delivering coal, cooling wind enters in windband pipe by wind-distributing pipe, thus fire coal is dispelled and is sent into the burner hearth emulsion zone of air stove at pipe end of delivering coal, be conducive to improving coal-fired efficiency of combustion, reduce production cost.
2, in each emulsion zone of air stove, two these spiral coal conveyors it are provided with, it is to avoid in actual production, the truce phenomenon that wherein a coal conveyor causes because of Emergency Maintenance, be conducive to improving Homes Using TV, reduce production cost.

Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, 2, it is provided that a kind of spiral coal conveyor, including the pipe 3 and be arranged on the auger 4 of delivering coal delivering coal in pipe 3 of delivering coal of hollow；Auger 4 of delivering coal includes helical axis 10, be arranged on helical axis 10 helical blade 11 and the shaft coupling head 12 being installed on helical axis 10 end, shaft coupling head 12 is connected with being positioned at the reductor 7 outside pipe 3 of delivering coal；
Delivering coal and be arranged with a windband pipe 2 on pipe 3, windband pipe 2 is provided with wind-distributing pipe 8, and wind-distributing pipe 8 extends to deliver coal in pipe 3, and pipe 3 of delivering coal is additionally provided with by coal bunker 5, and pipe 3 of delivering coal is provided with discharging opening away from the end by coal bunker 5.
Optimal enforcement example of the present utility model, as it is shown on figure 3, one end of windband pipe 2 blocks with pipe 3 outer wall of delivering coal and welds, the other end is provided with the thermal insulation board 1 of horseshoe type；Shaft coupling head 12 is connected with reductor 7 by coupling band 6；The back-up ring 9 for bolt location it is provided with between shaft coupling head 12 and coupling band 6；Helical blade 11 is welded on helical axis 10, and helical blade 11 is coated with nickel tungsten scuff-resistant coating.
