Description

Helical blade and paver
Technical field
The present invention relates to paver field, particularly relate to a kind of helical blade and be configured with the paver of this helical blade.
Background technology
In recent years, asphalt remixer has become as build ordinary highway and the indispensable special equipment of high-grade highway.Helical blade is a vitals of paver, and major function is the asphalt that scraper plate feeder is sent here, the two ends of hopper of dividing right and left.There is problem below in existing helical blade:
1, when helical blade rotates, asphalt is big with the shearing resistance of helical blade, and asphalt is big with the flow resistance of helical blade, and asphalt mixture segregation phenomenon is serious, and then causes that the internal the Nomenclature Composition and Structure of Complexes of asphalt is uneven.
2, helical blade generally uses low-alloy steel and ordinary white cast iron manufacture, and its wearability is low, and service life is short, is generally 1~3 month.Additionally, also have the helical blade and the helical blade of Cr28 Alloys Casting that adopt potassium steel casting, the helical blade impact flexibility of potassium steel casting is pretty good, but under low impact stress hardness poor, wearability is not enough;The helical blade of Cr28 Alloys Casting, has good wearability when as cast condition, but relatively costly, is unfavorable for that batch uses.It addition, also have the helical blade outer surface Bulk coat hard alloy being matrix with potassium steel high-abrasive material, although this mode adds the wearability of helical blade, but cost also improves.Paver pave asphalt process in, owing to the abrasion resistance of sub-material blade is bad and cause lot of materials waste and cost increases, simultaneously also have impact on the operation of a machine rate.Additionally, frequently change blade to too increase the labor intensity of workman, consume a large amount of human and material resources and financial resources.
Therefore, reduce the sub-material resistance of asphalt remixer helical blade to reduce the isolation of asphalt, improve the abrasive resistance of helical blade to extend the service life of helical blade, have great importance.
Summary of the invention
For solving the problems referred to above, the present invention provides a kind of helical blade and is configured with the paver of this helical blade, and it can reduce the isolation of asphalt and can reduce the abrasion of helical blade.
For achieving the above object, the helical blade of the present invention, including blade body and be arranged on described blade body side, connector for described blade body being connected with axle, described blade body includes first surface and the second surface relative with described first surface, and in the first surface of described blade body and second surface, the longitudinal hatching line of at least one is wave molding.
Preferably, the first surface of described blade body and longitudinal hatching line of second surface are wave molding.
Preferably, described blade body and described connector are structure as a whole.
Preferably, described blade body and described connector are Split type structure, and described blade body is welded with described connector.
The invention also discloses a kind of paver, it is configured with as above helical blade described in any one.
The helical blade of the present invention and paver, the first surface of helical blade is or/and second surface longitudinal direction hatching line is wave molding, and formation is that corrugated first surface is or/and the trough of second surface can effectively contain the wedge angle of asphalt.Along with the not stall of helical blade is moved, in corrugated first surface or/and second surface can alleviate the shearing resistance of asphalt and blade, thus reducing the flow resistance of asphalt and helical blade, reduce the isolation of compound.Simultaneously; the trough of this corrugated surface helical blade can adhered portion asphalt; the asphalt of this part can become the protective layer of helical blade; make helical blade operationally; asphalt on helical blade and other asphalts wear and tear mutually; reduce helical blade self abrasion, extend service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of helical blade of the present invention;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
Detailed description of the invention
Below, in conjunction with accompanying drawing, the structure and operation principle etc. of the present invention is described in further detail.
As shown in Figures 1 to 3, the helical blade of the present invention, including blade body 1 and be arranged on blade body 1 side, connector 2 for blade body 1 being connected with axle, blade body 1 includes first surface 101 and the second surface 102 relative with first surface 101, and in the first surface 101 of blade body 1 and second surface 102, the longitudinal hatching line (first surface 101 formed after the longitudinal section view of blade body 1 and the contour line of second surface 102 are for longitudinal hatching line) of at least one is for wave molding.Specifically, first surface 101 is or/and second surface 102 is formed as corrugated surface along its width, and first surface 101 is or/and the second surface 102 longitudinal hatching line in its optional position is wave molding.
In the present invention, blade body 1 and connector 2 can be structure as a whole, and are namely integrally machined formation by usual manners such as castings.Certainly, it can also be Split type structure, and blade body 1 is connected by mode or other usual ways welded with connector 2.
As it can be seen, connector 2 is positioned on the downside of blade body 1, connector 2 includes bearing shell 201, being provided with protuberance 202 on bearing shell 201, this protuberance 202 is provided with U-lag 203 near the position at two ends, is provided with through hole 204 in U-lag 203, for installing bolt, helical blade is connected with axle.
For improving isolation ability and the abrasive resistance of helical blade further, in the present invention, the first surface 101 of blade body 1 and longitudinal hatching line of second surface 102 are wave molding.So, two surfaces of helical blade are all formed as corrugated surface, and when helical blade works, corrugated first surface 101 and second surface 102 can alleviate the shearing resistance between helical blade and asphalt, reduce the isolation of asphalt.
As it is shown on figure 3, it illustrates longitudinal hatching line of first surface 101 and second surface 102.Corrugated longitudinal hatching line of first surface 101 and second surface 102 all includes crest 103 and trough 104.This crest 103 and trough 104 extend along the helix length direction of helical blade, define corrugated first surface 101 and second surface 102.During use, part asphalt can be attached on trough 104 so that this part asphalt becomes the protective layer of helical blade.When helical blade rotates, abrasion can be produced between crest 103 and the asphalt of first surface 101 and second surface 102, but, the trough 104 of first surface 101 and second surface 102 has part asphalt owing to sticking, the asphalt of this part asphalt and other positions produces abrasion, and will not produce abrasion between trough 104 and asphalt.Therefore, the corrugated surface of first surface 101 and second surface 102 is arranged, and also reduces the abrasion of helical blade, extends its service life.
The invention also discloses a kind of paver, it is configured with the helical blade of as above any one.Adopting the paver of this helical blade, helical blade isolation situation improves, and helical blade abrasion alleviates, it is ensured that the whole work efficiency of paver.
During use, first surface 101 is or/and the trough 104 of second surface 102 can effectively contain the wedge angle of asphalt, along with the not stall of helical blade is moved, the corrugated first surface 101 of helical blade is or/and second surface 102 can alleviate the shearing resistance of asphalt and blade, thus reducing the flow resistance of asphalt and helical blade, reduce the isolation of compound.The trough 104 of helical blade can adhered portion asphalt; the asphalt of this part can become the protective layer of helical blade; making helical blade operationally, the asphalt on helical blade and other asphalts wear and tear mutually, thus reducing the abrasion of helical blade.
