Definitions
- the present invention relates to a screw conveyor and a shield machine including the same.
- Ribbon-type screw conveyors have the advantage of being able to transport larger chunks (e.g., cocoons) compared to shaft-type screw conveyors.
- the ribbon screw conveyor has a through hole formed at the center of the auger when viewed from the axial direction. Therefore, when the conveyed product contains a large amount of water, there is a problem that the water barrier property is low.
- an object of the present invention is to provide a screw conveyor which can convey a large block and has high water barrier property, and a shield machine including the same.
- the screw conveyor has a spiral auger and a central axis extending along a center line of the auger, and has a spiral shape in phase with the auger. And the formed central axis.
- the central axis since the central axis exists, no through hole is formed at the center of the auger when the screw conveyor is viewed from the axial direction. Therefore, the water barrier property can be enhanced. Moreover, since the central axis is in a spiral shape, it is possible to transport a larger mass than in the case where the central axis is linear as in the prior art. Furthermore, since the spiral shape of the central axis is in the same phase as that of the auger, the transported object can be flowed at the same timing as the auger even at a position along the central axis.
- the outer peripheral surface of the central axis may be smoothly connected to both wing surfaces of the auger. According to this configuration, for example, if the central axis and the auger are integrally manufactured by casting, the connection between the central axis and the auger becomes unnecessary, and the cost can be reduced.
- the minimum distance from the center line of the auger to the outer peripheral surface of the center axis may be 1/20 or less of the outer diameter of the auger.
- the screw conveyor according to another aspect of the present invention is a ribbon screw conveyor, and includes a spiral auger, and a plurality of protrusions provided on the inner circumferential surface of the auger and extending to the center line of the auger. And.
- the screw conveyor according to still another aspect of the present invention is a ribbon type screw conveyor, and includes a spiral auger, and the distance from the center line of the auger to the inner circumferential surface of the auger is substantially It is characterized by being zero.
- substantially no through hole is formed at the center of the auger when the screw conveyor is viewed in the axial direction. Therefore, it is possible to enhance the water blocking property while taking advantage of the ribbon type screw conveyor that can transport a large mass.
- a shield machine according to the present invention is characterized by including the above-described screw conveyor.
- a screw conveyor capable of transporting a large block and having high water barrier property.
- FIG. 1A is a side view of a screw conveyor according to a first embodiment of the present invention
- FIG. 1B is a cross-sectional view of the screw conveyor
- FIG. 2A is a side view of a screw conveyor according to a second embodiment of the present invention
- FIG. 2B is a cross-sectional view of the screw conveyor
- FIG. 3A is a side view of a screw conveyor according to a third embodiment of the present invention
- FIG. 3B is a cross-sectional view of the screw conveyor. It is a perspective view of the screw in a 3rd embodiment.
- FIG. 5A is a side view of a screw conveyor according to a fourth embodiment of the present invention
- FIG. 5B is a cross-sectional view of the screw conveyor.
- FIG. 6A is a side view of a conventional screw-type screw conveyor
- FIG. 6B is a cross-sectional view of the screw conveyor.
- FIGS. 1A and 1B show a screw conveyor 1A according to a first embodiment of the present invention.
- the screw conveyor 1A includes a screw 3A and a cylindrical casing 2 accommodating the screw 3A.
- the screw conveyor 1A is mounted on, for example, a shield machine.
- the screw 3A includes a helical auger 5 and a central axis 4 extending along a central line L of the auger 5.
- the central shaft 4 and the auger are joined by welding.
- the central axis 4 is formed in a spiral shape in phase with the auger 5.
- the central axis 4 is corrugated so as to be convex toward the cross section of the auger 5.
- the minimum distance D2 from the center line L of the auger 5 to the outer peripheral surface 41 of the center axis 4 is 1/20 or less of the outer diameter D1 of the auger 5 Is desirable. More desirably, the minimum distance D2 from the center line L of the auger 5 to the outer peripheral surface 41 of the center axis 4 is 1/40 or less of the outer diameter D1 of the auger 5.
- the central axis 4 since the central axis 4 is present, no through hole is formed at the center of the auger 5 when the screw conveyor 1A is viewed from the axial direction. Therefore, the water barrier property can be enhanced. Moreover, since the central axis 4 is helical, it is possible to transport a larger mass 10 as compared to the screw conveyor 100 in which the conventional central axis is linear as shown in FIGS. 6A and 6B. Furthermore, since the spiral shape of the central axis 4 is in the same phase as the auger 5, the conveyed product can be flowed at the same timing as the auger 5 even at a position along the central axis 4.
- Second Embodiment 2A and 2B show a screw conveyor 1B according to a second embodiment of the present invention.
- the same components as those of the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.
- the screw conveyor 1B of the present embodiment includes a screw 3B in which the central shaft 4 and the auger 5 are integrated in appearance.
- the outer peripheral surface 41 of the central shaft 4 is smoothly connected to both wing surfaces 51 and 52 (51: transport surface, 52: non-transport surface) of the auger 5.
- the outer peripheral surface of the central axis 4 and the wing surfaces 51 and 52 of the auger 5 form a hemispherical curved surface in the longitudinal cross section including the center line L of the auger 5.
- FIGS. 3A and 3B and FIG. 4 show a screw conveyor 1C according to a third embodiment of the present invention.
- the screw conveyor 1C of the present embodiment is a ribbon type screw conveyor, and includes a screw 3C that does not have the central axis 4.
- the screw 3 ⁇ / b> C includes a spiral auger 5 and a plurality of protrusions 6 provided on the inner circumferential surface of the auger 5.
- Each protrusion 6 extends from the inner circumferential surface of the auger 5 to the center line L of the auger 5. That is, as shown in FIG. 4, the projections 6 are arranged to form a spiral staircase.
- Fourth Embodiment 5A and 5B show a screw conveyor 1D according to a fifth embodiment of the present invention.
- Screw conveyor 1D of this embodiment is a ribbon type screw conveyor, and includes screw 3D which does not have central axis 4.
- the screw 3D includes a spiral auger 5.
- the distance from the center line L of the auger 5 to the inner circumferential surface of the auger 5 is substantially zero (e.g., 10 mm or less).
- the through hole is not substantially formed at the center of the auger 5. Therefore, it is possible to enhance the water blocking property while taking advantage of the ribbon-type screw conveyor that can transport the large lumps 10.
