Embodiment Construction

[0023] In order to further explain the technical solutions of the present invention, specific examples are given below to illustrate in detail.

[0024] A blade connection structure of a mixer screw shaft of the present invention, such as Figure 1-5 As shown, it includes a helical screw shaft main body 1 and wear-resistant blades 2 fixedly covered on the working surface of the screw shaft main body 1 .

[0025] The improvement is that the wear-resistant blade 2 includes a plurality of blade monomers 21 arranged in sequence along the helical extension direction of the screw shaft main body 1; each blade monomer 21 is welded together with both sides of the working surface of the screw shaft main body 1 , and the adjacent blade monomers 21 are welded together. In the actual use process, since the wear-resistant blade 2 is composed of multiple blade monomers 21, the wear-resistant blade 2 can reduce the wear-resistant blade 2 when it is covered along the main body 1 of the screw ...

Abstract

The invention provides a blade connection structure of a mixer screw shaft. The blade connection structure comprises a screw shaft main body and a wearable blade. The wearable blade comprises blade units which are orderly arranged along a screw shaft main body spiral-extension direction. The blade units are welded to two sides of a work surface. Every adjacent blade units are welded so that the blade units form an integral body. The blade connection structure breaks through a structure form of the traditional mixer screw shaft. The wearable blade comprises the blade units so that a deformation degree of the wearable blade in arrangement along a screw shaft main body direction is reduced and fixed joint stress concentration is reduced and machinery comprehensive properties are improved. The blade units are welded to two sides of the work surface so that the blade units can be tightly combined with the screw shaft main body. Every adjacent blade units are welded so that the blade units form the integral bearing wear-resistant surface thus an interlocking fixing structure is formed and falling-off is difficult. Compared with the prior art, the blade connection structure has a tighter structure, realizes firm blade combination, and has a simple process, a low cost and a long service life.

Description

technical field [0001] The invention relates to a stirring device in the field of mixers such as concrete, in particular to a blade connection structure of a screw shaft of a mixer with better working performance. Background technique [0002] The performance of the screw shaft determines the overall performance of the mixer such as concrete. The traditional screw shaft mixing device, such as the Chinese utility model patent CN200820145336.7, discloses a double screw shaft concrete mixer, which is equipped with a body, a first mixing system and a second mixing system. ;The first mixing system is provided with a left shaft head, a right shaft head and 4 screw shafts, the 4 screw shafts include the inner return unit shaft, the outer return unit shaft, the outer feed unit shaft and the inner feed unit shaft, and the outer feed unit shaft The left end of the unit shaft and the left end of the inner feed unit shaft are respectively connected to the left shaft head, the right end ...
