Description
Technical field
The present invention relates to construction implement technical field, particularly relate to a kind of mixer.
Background technology
Mixer, is that a kind of blade-carrying axle rotates in cylinder or groove, plurality of raw materials is uniformly mixed, makes it the machine becoming a kind of mixture or suitable denseness.Mixer is mainly divided into forced mixer, single horizontal shaft blender, twin-shaft mixer these three kinds.
Mixer common in building is cement concrete mixer, and its purposes is exactly the mixing cement concrete of mechanization, and its kind is more.
One, cycle operation formula and continuous operating two kinds is divided into by operating type.
The feed of cycle operation formula, stirring, discharging three process were undertaken by the certain time interval cycle, namely by part mixing.Because the various materials of mixing are all through weighing accurately, therefore mixing quality is good; Therefore the operating type of this type is mostly adopted in actual use.
The above-mentioned three process of continuous operating carries out continuously in a longer cylindrical shell.Although its productivity ratio comparatively cycle operation formula is high, because the match ratio of each material, mixing time are difficult to control, therefore mixing quality is poor, and actual use is less.
Two, be divided into by agitating mode that gravity type stirs, forced action type stirs two kinds.
Self-dumping mixer is exactly that compound is placed in a mixing drum rotated, and along with the rotation of mixing drum, the blade in drum rises to certain height compound, then freely scatters by deadweight.Carry out so again and again, till mixing thoroughly.The general mixing plasticity of this mixer and semi plastic concrete.
Forced mixer is that mixing drum is motionless, and by the blade action of forced stirring that rotating shaft in drum is all put.This mixer mixing quality is good, and production efficiency is high; But power consumption is large, and blade wear is fast.Generally be applicable to mixing dry concrete.
Forced mixer common in prior art adopts the structure of holes drilled through on shaft, and this structural deterioration original rigidity of steel, reduce shaft deflection, thus the life-span of axle are shorter.
Publication number is CN203170238U, publication date is that the Chinese patent literature of on 09 04th, 2013 discloses a kind of biaxial rneader, comprise motor, pneumatic clutch, decelerator, uncovered agitator tank, described motor is by pneumatic clutch connection reducer, it is characterized in that: described biaxial rneader also comprises two shafts and a protective cover, described two shafts are set in parallel in described agitator tank, described shaft is arranged with stirring blade, one end of described two shafts is all connected with the output shaft of decelerator, described protective cover is fixed on the top of described agitator tank, and the size of protective cover and described agitator tank is uncovered in the same size, a plurality of reinforcements of spaced set on described protective cover.
Biaxial rneader disclosed in this patent document, stirring blade is directly set on shaft, one end of shaft is directly connected with the output shaft of decelerator, connected mode adopts two pieces cross shaft coupling head to connect, wherein a cross shaft coupling head is assemblied on shaft, and another part cross shaft coupling head is assemblied on reductor slow-speed shaft, its span stirring arbor is excessive, after equipment Long-Time Service, mixer shaft deflection is excessive, stir the flexible distortion of arbor, thus it is not high to cause stirring material amount of cure, brickmaking weak effect; Stirring blade blade is directly through at the structure stirred on arbor, can affect the rigidity of axle, shortens the service life of stirring arbor; Meanwhile, this project organization also can make stirring blade blade exchanging difficulty, the consumable accessory replacement cost of adding users in equipment use.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of mixer, the present invention adopts off-axis structure, effectively can reduce the amount of deflection stirring arbor, prevent stirring arbor and occur bending and deformation, thus ensure to stir material amount of cure, improve brickmaking effect, stirring blade blade is arranged on shaft by stirring tool rest, enhances the rigidity of shaft, extends the service life of shaft.
In order to realize foregoing invention object, the technical solution used in the present invention is:
A kind of mixer, comprise motor, clutch, reductor, agitator tank, shaft, stirring blade blade, motor connects reductor by clutch, shaft is driven by motor, it is characterized in that: also comprise the first clamping coupling, second clamping coupling, front di-bearing block, rear di-bearing block, described shaft is made up of the stirring minor axis be positioned at outside agitator tank and the stirring major axis being positioned at agitator tank, described stirring minor axis one end is connected with the slow-speed shaft of reductor by the first clamping coupling, the other end is connected with the brearing bore of front di-bearing block, described stirring major axis one end is connected with the brearing bore of front di-bearing block by the second clamping coupling, the other end is connected with the brearing bore of rear di-bearing block, on described stirring major axis, cover has protecting sleeve for thread, and screw thread protection puts and is welded with stirring tool rest, and described stirring blade blade is bolted on and stirs on tool rest.
