Abstract
The utility model discloses a spiral blade. The spiral blade adopts a flat sector-shaped structure transversely and a spiral structure longitudinally, twisting directions of the inner-side surface and the outer-side surface of the blade are opposite, and the inner-side surface and the outer-side surface form a spiral twisting structure; a mounting groove is formed in the front side of the blade, and mounting holes are formed in the mounting groove; a bulging rib is arranged on the upper edge of the back side of the blade. The spiral blade is smooth and clean in surface, high in strength, smooth in material conveyance and capable of bearing larger reverse thrust to prevent a stirring shaft from being broken by materials during reverse stirring of the materials.
Description
Technical field
The utility model belongs to concreting machinery field, relates in particular to a kind of helical blade.
Background technology
Vane type concrete mixer is a kind of more common mixer, and its operation principle is mainly to rotate and constantly push promotion mixture by being provided with the shaft of a plurality of stirring vanes, thereby mixture is mixed.
Blade of stirrer is most important for the mixing effect of mixer, and the mixing effect of existing blade of stirrer is general, and wearability is poor.
Utility model content
The purpose of this utility model is to provide a kind of helical blade, is intended to solve existing mixer mixing effect general, the problem wearing no resistance of blade.
The technical solution of the utility model is as follows:
A helical blade, includes blade body, and blade body is laterally flat sector structure, is longitudinally helical structure, and the inner surface of blade body is contrary with the hand of spiral of outer surface, and inner surface and outer surface form screw twisted shapes; The front of blade body is provided with mounting groove, has installing hole on mounting groove.
Further, the upper limb at the described blade body back side is provided with a raised ribs.
Further, the mass ratio of the component of described helical blade is:
C:2.6%-3.2%, SI :≤0.5%, Mn:0.8%-1.0%, P≤0.05%, S≤0.05%, Cr:14-18% CU:0.5%-0.8%, surplus is Fe.
The beneficial effects of the utility model are as follows:
Helical blade surface of the present utility model is bright and clean, and intensity is high, and mass transport is smooth, and it can bear larger deboost, can not cause the fracture of material to shaft while making material carry out reverse agitating function.
Accompanying drawing explanation
Fig. 1 is the Facad structure schematic diagram of the helical blade that provides of the utility model embodiment;
Fig. 2 is the structure schematic diagram of the helical blade that provides of the utility model embodiment;
Fig. 3 is the top view of the helical blade that provides of the utility model embodiment;
Number in the figure: 1, mounting groove; 2, installing hole; 3, raised ribs; Blade body 4.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to accompanying drawing, a kind of helical blade, includes blade body 4, and blade body 4 is laterally flat sector structure, is longitudinally helical structure, and the inner surface of blade body 4 is contrary with the hand of spiral of outer surface, and inner surface and outer surface form screw twisted shapes; The front of blade body is provided with mounting groove 1, has installing hole 2 on mounting groove 1, and the upper limb at blade body 4 back sides is provided with a raised ribs 3.
The mass ratio of the component of described helical blade is:
C:2.6%-3.2%, SI :≤0.5%, Mn:0.8%-1.0%, P≤0.05%, S≤0.05%, Cr:14-18% CU:0.5%-0.8%, surplus is Fe.
Helical blade surface of the present utility model is bright and clean, and intensity is high, and mass transport is smooth, and it can bear larger deboost, can not cause the fracture of material to shaft while making material carry out reverse agitating function.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that performing creative labour can make or distortion still within protection domain of the present utility model.
