Description

Agitator using hybrid mixing arm

Technical field

This utility model is related to a kind of bituminous mixing plant, more particularly, to a kind of agitator using hybrid mixing arm.

Background technology

Bituminous mixing plant, also can be called asphalt concrete mixer, and this equipment can produce asphalt, modified pitch mixes Close material, chromatic bitumen mixture, fully meet the needs building highway, standard highway, town road, airport, harbour etc..

, as the core component of bituminous mixing plant, user's attention rate is very high all the time for agitator, and for traditional right Put the mixing arms' arrangement form of blade, because mixing arm and blade quantity are many, the gross area is big, lead to stirring energy consumption too high, select Power of motor is bigger than normal, have impact on the overall performance of mixing plant；Additionally, due to the bump to agitator for the compound, cause to stir The vibration of framework or even whole building body increases, infringement building body life time.

Content of the invention

The problem existing for above-mentioned prior art, this utility model provides a kind of stirring using hybrid mixing arm Device, can reduce stirring energy consumption on the premise of ensureing mixing uniformity, and significantly reduces compound to agitator or even whole The impact of individual building body, thus mitigate the vibration that main building causes because of agitator work.

To achieve these goals, the technical solution adopted in the utility model is: a kind of stirring using hybrid mixing arm Mix device, including setting agitating device in agitator housing, emptying door, agitating device and synchromesh gear, described agitator housing, stir Mix device to be connected with the synchromesh gear outside agitator housing, agitator housing bottom arranges emptying door；Described agitating device includes First shaft and the second shaft, bearing, singly put blade mixing arm, opposed blades mixing arm and opposed return blade stirring Arm；Described first shaft and the second shaft are arranged in agitator housing by bearing；First shaft and the second stirring The arrangement of axle mixed interval is multigroup singly to put blade mixing arm, multigroup opposed blades mixing arm, and one group of opposed return blade mixing arm, Opposed blades mixing arm on adjacent two shafts is staggered, the opposed return blade mixing arm on adjacent two shafts interlocks Arrangement, under the stirring vane effect of two shafts, compound forms in agitator and encloses stream motion.

This utility model is further, and described agitator housing inwall arranges abrasion-proof backing block.

This utility model is further, and described bearing is installed shaft end seal.

This utility model is further, and described first shaft and the second shaft mixed interval arrange three groups of lists and put blade Mixing arm, three groups of opposed blades mixing arms.

Compared with prior art, this using new beneficial effect is: first, singly put blade mixing arm and stir with opposed blades Mix the mixing arrangement of arm, contribute to reducing the stirring vane gross area to greatest extent on the premise of ensureing mixing uniformity, thus Reduce stirring energy consumption；Second, this hybrid mixing arm can make stirring vane be changed into noncontinuity to the thrust of compound, Effectively reduce the impulsive force to agitator axial direction for the compound, the stability of lift agitator or even whole building body.

Brief description

Fig. 1 is structural representation of the present utility model；

Fig. 2 is this utility model mixing arm schematic top plan view；

Fig. 3 is this utility model mixing arm schematic front view.

In figure: 1, agitator housing, 2, abrasion-proof backing block, 3, emptying door, 4, agitating device, 5, synchromesh gear, 6, first stirs Mix axle, 7, bearing, 8, singly put blade mixing arm, 9, opposed blades mixing arm, 10, opposed return blade mixing arm, 11, axle head close Envelope, the 12, second shaft.

Specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in figure 1, this utility model use hybrid mixing arm agitator, including agitator housing 1, emptying door 3, Agitating device 4 setting agitating device 4, agitating device 4 and agitator housing in agitating device 4 and synchromesh gear 5 agitator housing 1 Synchromesh gear 5 outside 1 connects, and agitator housing 1 top arranges emptying door 3；Agitating device 4 includes the first shaft 6 and second Shaft 12, bearing 7, singly put blade mixing arm 8, opposed blades mixing arm 9 and opposed return blade mixing arm 10；First stirring Axle 6 and the second shaft 12 are arranged in agitator housing 1 by bearing 7；Between the first shaft 6 and the second shaft 12 mixing Every arrange multigroup singly put blade mixing arm 8, multigroup opposed blades mixing arm 9, and one group opposed return blade mixing arm 10, adjacent Opposed blades mixing arm 9 on two shafts is staggered, the opposed return blade mixing arm 10 on adjacent two shafts interlocks Arrangement, under the stirring vane effect of two shafts, compound forms in agitator and encloses stream motion.

When making work, synchromesh gear 5 drives two shafts to rotate, due to singly putting blade mixing arm 8 and opposed leaf simultaneously The mixing arrangement of piece mixing arm 9, the opposed blades mixing arm 9 on adjacent two shafts is staggered, and contributes to ensureing stirring Reduce the stirring vane gross area to greatest extent, thus reducing stirring energy consumption on the premise of uniformity；It is provided with one group of opposed return Blade mixing arm 10, reversely rotates in stirring, and this hybrid mixing arm can make stirring vane that the thrust of compound is become For noncontinuity, effectively reduce the impulsive force to agitator axial direction for the compound, the stability of lift agitator or even entirety.

On the basis of said structure, this utility model arranges abrasion-proof backing block 2 in agitator housing 1 inwall.Mill for workpiece Damage and provide important wear-resistant protection measure, improve the service life of equipment, workpiece.On bearing 7, shaft end seal 11 is installed, Prevent the media such as lubricating oil from leaking outside.

The quantity of this utility model mixing arm can be adjusted according to actual needs, this utility model preferably first shaft 6 and the second shaft 12 mixed interval arrange three groups of lists put 8, three groups of opposed blades mixing arms 9 of blade mixing arm.

Certainly, above-described embodiment is only preferred version of the present utility model, is specifically not limited thereto, and on this basis may be used Make according to actual needs having and targetedly adjust, thus obtaining different embodiments.Due to mode in the cards relatively Many, just no longer illustrate one by one here.
