Description
Technical field
The utility model is related to biomass material conveying technology field, specially a kind of biomass silo multi-diameter shaft spiral is unloaded
Material machine.
Background technology
The helical feed discharging bin that material in raw material material bin passes through bottom.Since biomass material is easily agglomerating and winding
Etc. characteristics, in the transmission process that discharges, other than helical blade conveys material, the material on helical axis top also can forward with
It walks together.After these raw materials to storehouse antetheca cannot whole exports, therefore be extruded at this, the more press the more tight, finally can stuck spiral shell
Rotation.
The conveying capacity and rotating speed of spiral, the outer diameter of spiral, axle diameter, screw pitch are related.For same root spiral, before rotating speed
It is identical afterwards, for outer diameter due to the clearance requirement between adjoining spiral and identical, variation can only be that screw pitch and mandrel are straight
Diameter.And the way of conventional discharge auger is using variable-pitch propeller, i.e., screw pitch gradually increases the screw pitch of spiral from back to front, makes spiral shell
The conveying capacity for revolving front end is more than the conveying capacity of rear end, reduces the possibility of forepart blocking.But it is often not met by requiring in this way,
Or blocking can occur.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of biomass silo multi-diameter shaft screw discharging machine, energy
Enough outside the more material web discharging bins in front end, to reduce the fore extruding of material, discharging is more smooth.
Its technical solution is such：A kind of biomass silo multi-diameter shaft screw discharging machine, including feed bin, the feed bin
Lower end is provided with screw discharging machine, and the screw discharging machine includes the discharging warehouse for connecting the bin bottom, the discharging bin
It is provided with helical axis in vivo, which is characterized in that the helical axis is three-level multi-diameter shaft, and the three-level multi-diameter shaft is close to the material
The diameter of storehouse side is more than the diameter of the discharging warehouse outlet side, is equipped with variable-pitch propeller blade on the helical axis, leans on
The helical blade spacing of the nearly feed bin side is more than the helical blade spacing of the discharging warehouse outlet side.
It is further characterized by arranged side by side in the screw discharging machine there are four the helical axis；
The minimum diameter section of the three-level multi-diameter shaft is not provided with the helical blade.
After the structure of the utility model, the spiral of the utility model employs three-level ladder, i.e. the mandrel of spiral is straight
Diameter is being axially different, and more smaller toward the port of export, the conveying capacity of such port of export will be bigger, and cooperation spacing becomes larger
The more materials in front end can be taken out of discharging bin body by helical blade, reduced the fore extruding of material, made spiral discharging more suitable
Freely.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model the structure left view.
Specific embodiment
See Fig. 1, shown in Fig. 2, a kind of biomass silo multi-diameter shaft screw discharging machine, including feed bin 1,1 lower end of feed bin is set
Screw discharging machine is equipped with, screw discharging machine includes the discharging warehouse 2 of 1 bottom of connection feed bin, and helical axis is provided in the warehouse 2 that discharges
3, helical axis 3 is three-level multi-diameter shaft, and diameter of the three-level multi-diameter shaft close to 1 side of feed bin is more than discharging warehouse 2 and exports 4 sides
Diameter is equipped with variable-pitch propeller blade 5 on helical axis 3, and the helical blade spacing close to 1 side of feed bin is more than discharging warehouse 2 and goes out
The helical blade spacing of 4 sides of mouth.Helical axis 3 there are four being arranged side by side in screw discharging machine；The minimum diameter of three-level multi-diameter shaft
Section is not provided with helical blade.7 be material in figure, and 6 be driving motor.
