Abstract

The utility model relates to the field of concrete mixers, and particularly relates to a forced concrete mixer with double horizontal shafts. The forced concrete mixer comprises a charging barrel, two mixing shafts, more than one lining plate and mixing blades, wherein the two mixing shafts are arranged in parallel in the charging barrel; the lining plates are closely arranged and fit along the inner wall of the charging barrel; and the mixing shaft is provided with the mixing blades. The forced concrete mixer is characterized in that the lining plates and the mixing blades are made of wear-resisting steel plates; one side of the lining plate and one side of the mixing blade are respectively vertically welded with 2-5 bolts; a side facing the materials and an end part of the mixing blade are respectively provided with a wear-resisting welding rod overlaying layer, of which the edge width is 10-50mm. Compared with the prior art, the forced concrete mixer has the beneficial effects that: 1) the structure production process is simple, and serialization production can be realized; 2) the lining plates and the mixing blades are good in wear-resisting property, and long in service life; and 3) after being abraded, the overlaying layer of the mixing blade can be subjected to repair welding.

Description

A kind of double-horizontal-shaft forced type concrete mixer

Technical field

The utility model relates to the concrete mixer field, relates in particular to a kind of double-horizontal-shaft forced type concrete mixer.

Background technology

At present, liner plate in the concrete mixer barrel and stirring vane all adopt wear-resistant cast iron material to make, owing to be cast member; Casting flaws such as ubiquity pore, slag inclusion; In use exist frangible, shortcoming such as be prone to split, casting liner plate thin and thick and hardness are inhomogeneous, quality is also unstable; Make the manufacture craft more complicated owing to need to make die model, the production cycle is longer.

To adopt high-strength bolt to be connected with the barrel wall fixing more for cast iron lining plate in addition, and nuts is prone to hang concrete, makes barrel be difficult for cleaning out; Nuts can cause liner plate to get loose because of after wearing and tearing come off, and is accidents caused.

Summary of the invention

The purpose of the utility model provides a kind of double-horizontal-shaft forced type concrete mixer, overcomes the deficiency of prior art, adopts the novel wear resistant steel plate to make liner plate and stirring vane, and it is simple to satisfy production technology, the requirement of long service life.

For solving the problems of the technologies described above, the technical scheme of the utility model is:

A kind of double-horizontal-shaft forced type concrete mixer; Comprise barrel, shaft, liner plate and stirring vane; Two shafts laterally arrange in barrel, and liner plate is one fits with upper edge material tube inner wall solid matter, and shaft is provided with stirring vane; Said liner plate and stirring vane are the wear-resisting steel plate material and process, and both sides are vertically welded respectively and are provided with 2-5 double-screw bolt.

Meeting of said stirring vane expects that side edge and end are respectively arranged with the wear resistance electrode overlay cladding, the wide 10-50mm in said overlay cladding edge.

Compared with prior art, the beneficial effect of the utility model is: 1) this structure production technology is simple, can realize producing in serial form; 2) good, the long service life of liner plate and stirring vane anti-wear performance; 3) after the wearing and tearing of stirring vane overlay cladding, can also repair welding.

The specific embodiment

Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:

See Fig. 1; Be a kind of double-horizontal-shaft forced type concrete mixer example structure of the utility model sketch map, comprise that barrel 1, shaft 2,

liner plate

3 and 4, two shafts 2 of stirring vane laterally arrange in barrel 1; Liner plate 3 is one and fits with upper edge barrel 1 inwall solid matter; Shaft 2 is provided with stirring vane 4, and liner plate 3 is the wear-resisting steel plate material with stirring vane 4 and processes, during making by drawing; Through numerical control water cutting equipment or digital controlling plasma cutting equipment wear-resisting steel plate is cut into various deformed steel flats, guarantee installation dimension.Said wear-resisting steel plate is the HARDOX500 material; It has high rigidity, high strength and high tenacity concurrently; Its hardness is through effectively quenching technical acquisition on the shrend live wire, and this method both can obtain higher hardness, can keep alloying component lower in the steel again.

See Fig. 2, Fig. 3; It is liner plate example structure sketch map; The low carbon steel plate base material side of liner plate 3 is provided with 2-5 double-screw bolt 1 with the arc stud welding vertical welding with welding positioner of meeting sb. at the airport, and the position of double-screw bolt 1 is corresponding with barrel the corresponding mounting hole, and general liner plate upper stud 1 is advisable with 2-3.

See Fig. 4, Fig. 5; It is stirring vane example structure sketch map; The vertical welding of the low carbon steel plate base material side of stirring vane 4 is provided with 2-5 double-screw bolt 26, and the position of double-screw bolt 26 is corresponding with shaft the corresponding mounting hole, and general stirring vane 4 upper studs 26 are advisable with 2.Meeting of stirring vane 4 expects that side edge and end also are provided with wear resistance electrode overlay cladding 7, the wide 10-50mm in overlay cladding 7 edges, and hardness can reach HRC61～62, after overlay cladding 7 wearing and tearing, can also repair welding.

Because wear-resisting steel plate has very high anti-wear performance and better impact property; Can adapt to multiple operations such as cutting, bending, welding; Can take multiple modes such as welding, plug welding, bolt connection to be connected with other structures; The production technology of concrete mixer is simplified greatly, met the requirement of producing in serial form.
