Definitions
- the present invention refers to a bucket mixer for mixing solid aggregates and delivering the mixture. More particularly, the invention relates to a bucket mixer for mixing solid aggregates such as concrete aggregates, of the kind comprising a vessel and an inner mixing screw rotating about an axis parallel to the longitudinal axis of the vessel.
- the bucket mixer of this invention is of the kind providing a plurality of blades mounted to the peripheral part of the mixing screw so as to extend radially as far as near to the edge of the vessel, the blades being oriented at a winding direction opposite to that of the mixing screw so as to attain the double effect of cleaning or scraping the vessel walls and urge the material in the opposite direction of that imparted by the mixing screw during operation of the bucket mixer.
- U.S. patent No. 4,223,996 discloses an apparatus of the above discussed kind and suggests that the blades can be welded or otherwise secured in a rigid manner, permanently or removably, to the peripheral part of the mixing screw. According to this document, fixing is accomplished by restraining the inner edge of the blade in a recess obtained in the mixing screw. This solution first of all weakens the mixing screw at the points where the recesses are. Further, it makes it difficult to provide a system for releasably securing the blade to the peripheral part of the mixing screw, as these two members are substantially at a right angle with respect to each other in a point where they undergo considerably high torsion stresses. Finally, for the same reasons also the blade tends to deform rapidly. Replacing the blade may become difficult or impossible due to the manner in which it is coupled to the mixing screw.
- Italian patent No. 1,210,783 discloses a bucket mixer of this kind wherein each blade is pivotally mounted to a support welded to the mixing screw, in order to rotate from a retracted position near the axis of the mixing screw to an extended position in proximity of the vessel.
- a bucket mixer for mixing solid aggregates and delivering the mixture, comprising counter-current mixing means of mixing screw-like kind extending substantially throughout the whole bucket mixer and blade-like mixing means carried by the peripheral part of the mixing screw and radially extending from the edge thereof to near the inner wall of the vessel, the blades being oriented at a winding direction opposite to that of the mixing screw, characterised in that the blades are rigidly and entirely fixed in releasable manner to supports welded to the peripheral part of the mixing screw.
- a bucket mixer of known kind provides a vessel 10 for containing the products to be mixed. Within vessel 10 there is mounted a mixing screw 11 rotating about a central longitudinal axle consisting of a shaft 12.
- blades 13 forming preset angles therebetween.
- the blades 13 are oriented perpendicular to the mixing screw 11 and directed towards the inner wall of the vessel 10, so as to provide counter-current mixing with respect to mixing screw 11 and clear the inside of vessel 10 during mixing.
- the blades 13 are rigidly fixed, for example by means of bolts 14, directly or indirectly, to a support 15 welded to the peripheral part of the mixing screw 11.
- the support 15 is a flat base. Interposed between the flat support 15 and the flat blade 13 there is an L-shaped bracket 16 connected by bolts to either members 13 and 15 (as shown in FIGS. 2 and 3) or only one of them.
- the support 15 is L-shaped and there are no intermediate brackets as there are bolts connecting the blade to the longer portion of support 15.
- the blade 13 is L-shaped so that its shorter portion is the one welded in 14 to support 15.
- the blade is rigidly fixed to the mixing screw but in such way as not to cause deformation in either bodies and be easily replaced when worn or in case of failure.
- no blades maintenance (washing) is required as there are no parts reciprocally moving during operation.
