Abstract
A stirring paddle comprises a connecting seat, a stirring shaft and blades, wherein the connecting seat is in a buckling and detachable mode with a left half part and a right half part, and a central shaft hole is drum-shaped, square or polygonal; the lower part of the stirring shaft is provided with a necking down, the section of the necking down corresponds to the central shaft hole, and the necking down is in interference fit with the central shaft hole. The cross-section of half connecting seat is similar T shape, and its buckling face is provided with unsmooth complex setting element and bolt hole. The utility model has the advantages of simple and reasonable structure, realize the fastening connection of connecting seat and (mixing) shaft through bolt and nut to realize radial and axial positioning between connecting seat and the (mixing) shaft through recess, boss, central shaft hole and the necking down that sets up. Therefore, the free assembly and disassembly between the blades and the stirring shaft are facilitated, the assembly efficiency in the production and maintenance process is improved, and the assembly difficulty is reduced.
Description
Technical field
The utility model relates to a kind of paddle, mainly is applicable to the stirring of cementation of fissures material on the pouring machine.
Background technology
In the prior art, paddle structure such as Fig. 1, shown in Figure 2, comprise mounting disc 1 ', shaft 2 ', angle steel 3 ' and blade 4 ', wherein mounting disc 1 ' be weldingly fixed on shaft 2 ' on, offer notch in the mounting disc with width such as blades, the blade that both sides are fixed with angle steel inserts notch, angle steel is close to and is welded on the mounting disc bottom surface, blade 4 ' be fixed together by connector and angle steel, the stirring arm of said structure is when assembling, part can't dismounting because shaft and mounting disc are welded as a whole, need earlier shaft integral body to be placed in the stir chamber, pass back and top drive disk assembly from the stir chamber cover plate again and be connected, like this bearing, sprocket wheel will assemble in the above, maintenance, dismounting is difficulty.Therefore assembly difficulty is bigger, and has the hidden danger of reduction equipment functional reliability.
China Patent No. 98208040.9 discloses a kind of vertical stirrer, comprises vertical shaft and the blade that is installed on the vertical shaft, and blade is that the center is symmetrically distributed with the vertical shaft; Blade is dull and stereotyped; Blade and vertical shaft are taked the connected mode of adjustable perfect square position.Above-mentioned agitator blade in actual applications is yielding and fracture, and shortened its service life.
The utility model content
The purpose of this utility model be intended to provide a kind of simple and reasonable, cost of manufacture is low, can improve produce or maintenance process in efficiency of assembling, reduce the paddle that installation difficulty, blade can not be out of shape or fracture, to overcome weak point of the prior art.
A kind of paddle by this purpose design comprises Connection Block, shaft and blade, and its architectural feature is that described Connection Block is removable for left and right sides two halves fasten, and its central shaft hole is cydariform, square or polygon; The bottom of shaft is provided with necking down, and its cross section is corresponding with central shaft hole, necking down and central shaft hole interference fit.
The cross section of described half Connection Block is similar T shape, and its buckling surface is provided with the keeper and the bolt hole of concavo-convex cooperation.Connection Block buckling surface one side is provided with groove, and opposite side is provided with boss, and the two halves Connection Block is an one by groove boss location and by bolted.
Described Connection Block both sides staight shank end is connected with blade.The Connection Block both sides are welded with angle steel, and blade is clamped between two angle steel.
The utility model is simple and reasonable, realizes being fastenedly connected of Connection Block and shaft by bolt and nut, and by the radial and axial location between the groove, boss, central shaft hole and necking down realization Connection Block and the shaft that are provided with.Therefore make things convenient for freely assembling and partition between blade and shaft, improved the efficiency of assembling in production and the maintenance process, and reduced assembly difficulty.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 3-Fig. 8, this paddle comprises Connection Block 1, shaft 2 and blade 4, and Connection Block 1 is removable for two halves fasten, and its both sides staight shank end 14 connects blade 4.The cross section of half Connection Block is similar T shape, and its buckling surface 15 1 sides are provided with groove 11, and opposite side is provided with boss 12, and the two halves Connection Block fastens as one by groove 11 boss, 12 location and by four bolts 5.Connection Block 1 both sides are welded with angle steel 3, and blade 4 is clamped between two angle steel 3,6 by bolt.Connection Block two staight shank ends were located at the both sides up and down of blade 4 central axis in 14 minutes.
Referring to Fig. 9-Figure 11, the central shaft hole 13 of Connection Block 1 is a cydariform, and the bottom of shaft 2 is provided with necking down, and its cross section is and central shaft hole 13 corresponding cydariforms, effectively like this prevents skidding of 1 of shaft 2 and Connection Block in the rotation process.Necking down and central shaft hole 13 are interference fit, are connected firmly, and make things convenient for the installation and the dismounting of shaft 2.The Connection Block buckling surface also can be realized fastening, location between the two halves Connection Block by the positioning tooth of concavo-convex cooperation is set.
