Abstract
The utility model relates to a screw shaft for a screw conveyor, which is formed by welding a tubular shaft and a screw blade; wear-resisting steel bars are welded on the edge of the outside diameter of the screw blade so as to prolong the service life; and in addition, after the wear-resisting steel bars are worn, new wear-resisting steel bars are supplemented, so that the maintenance cost can be reduced to the maximum extent.
Description
Technical field
The utility model relates to a kind of screw shaft that is used for conveyor screw.
Background technology
Conveyor screw is to rely on the rotation of screw shaft to come convey materials, owing to produce the phase mutual friction between the external diameter of helicallobe and the material, after work a period of time, external diameter diminishes, and when may wear to a certain degree, operational throughput reduces, will change whole screw shaft, particularly when carrying the big material of chiseling property of mill such as cement, iron powder, it is even more serious to wear and tear, and service life is shorter.
Summary of the invention
In order to improve the service life of screw shaft, the utility model provides a kind of spiral external diameter edge to be welded with the screw shaft of wear-resisting steel bar.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of screw shaft that is used for conveyor screw comprises tubular axis, helicallobe, and is welded with wear-resisting steel bar along helicallobe external diameter edge.
The cross-sectional plane of described wear-resisting steel bar is circular, and its diameter is greater than the thickness of helicallobe.
The beneficial effects of the utility model are, owing to be welded with wear-resisting steel bar on the external diameter of helicallobe, can prolong its service life, and after the wear-resisting in addition steel bar wearing and tearing, but the new wear-resisting steel bar of repair welding has also reduced maintenance cost to greatest extent.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view of A-A among Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of screw shaft that is used for conveyor screw, with helicallobe 2 successive weldings on tubular axis 1, and along the wear-resisting steel bar 3 of helicallobe external diameter edge successive welding.The cross-sectional plane of wear-resisting steel bar 3 is circular, and its diameter is greater than helicallobe 2 thickness 2mm to 5mm.
Claims (2)
1. a screw shaft that is used for conveyor screw comprises tubular axis (1), helicallobe (2), it is characterized in that being welded with wear-resisting steel bar (3) along helicallobe external diameter edge.
2. a kind of screw shaft that is used for conveyor screw according to claim 1, the cross-sectional plane that it is characterized in that described wear-resisting steel bar (3) is for circular, and its diameter is greater than the thickness of helicallobe (2).
