Abstract

The utility model discloses a double-shaft stirrer for a bituminous concrete regenerator, comprising a stirrer shell, a spindle, and a plurality of groups of stirring arms with stirring paddles, wherein the spindle is arranged on the stirrer shell, a plurality of groups of stirring arms are sheathed on the spindle, a chain wheel is arranged at one end of the spindle, a driven shaft is arranged on the stirrer shell, a plurality of groups of stirring arms are sheathed on the driven arm, and the other end of the spindle is connected with the driven shaft by a pair of synchronous gears. The stirrer adopts the design of double shafts, and after aggregates are added in the stirrer, the double shafts are ensured to rotate synchronously in the reverse direction by the synchronous gears, so that the space is saved and the production cost is reduced. The stirring paddles are arranged in spiral lines at intervals on the shaft, so that material can move in the radial direction and in the axial direction in stirring, so that the double-shaft stirrer is characterized in that the stirring is uniform, the structure is compact, the stirring efficiency is high, and the like.

Description

Asphalt concrete regenerating machine double-shaft mixers

Technical field

The utility model relates to a kind of construction of the highway machinery, relates in particular to a kind of asphalt concrete regenerating machine agitator.

Background technology

China's prosperity of economy has promoted the fast development of highway communication building cause, and the total kilometrage of China's speedway reaches more than 40,000 kilometer now, and about more than 650,000 kilometers of urban and rural highway total kilometrage occupies prostatitis, the world.But using and develop through the more than ten years, some speedways and A-road have entered big or middle repairing the stage in succession, for how in addition regeneration of a large amount of road surfaces obsolete material that in asphalt pavement conserving maintenance, the process transformed, is produced, be technical task in the highroad construction with great strategic importance.The regeneration of asphalt pavement material, can save a large amount of pitch and sandstone material, thereby can reduce the expense of road maintenance and maintenance and newly-built asphalt roads, be effectively addressed owing to the road surface obsolete material simultaneously, refuse obtains utilizing, and has saved natural resource, has avoided the environment pollution of waste asphalt mixture, positive progradation is played in the sustainable development of China's economy, and its economic benefit and social benefit are very considerable.

Just begin to use asphalt pavement regeneration the eighties as far back as eighties of last century abroad and utilize technology, asphalt pavement regeneration has been done daily application technology by American-European countries now, the asphalt pavement regeneration technology can be used for the maintenance construction of speedway, can also alleviate the generation of pavement crack when being used for basic unit effectively.At home, the key issue of promoting this technology is the plant issue of asphalt pavement regeneration, and for the Recycled Asphalt Pavement mixing plant, the price of overseas equipment is extremely high, and unit in charge of construction is difficult to bear.At present, the stirring of bituminous concrete is mainly finished and then is transported to the building site and lays by factory, is directed at the bituminous concrete that stirs temperature in transportation and reduces, solidifies, thereby influenced the functional performance of Recycled Asphalt Pavement.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, a kind of new structure asphalt concrete regenerating machine double-shaft mixers is provided, can finish the stirring and the laying of Recycled Asphalt Pavement at the scene, material can be moved radially in stirring, can move axially again, have stir, characteristics such as compact conformation, stirring efficiency height.

The technical scheme that realizes the utility model purpose is: a kind of asphalt concrete regenerating machine double-shaft mixers, the mixing arm that comprises agitator shell, main shaft, some groups of band stirrer paddles, described main shaft is installed on the described agitator shell, described some groups of mixing arms are sleeved on the described main shaft, end at described main shaft is equipped with sprocket wheel, it is characterized in that: on described agitator shell, driven shaft is installed, also be set with some groups of mixing arms at described driven shaft, linking to each other with described driven shaft by a pair of synchromesh gear at the other end of described main shaft.

Described stirrer paddle is by being bolted on the described mixing arm.

Described stirring blade forms on axle and is interrupted the helix arrangement.

The utility model compared with prior art has following advantage:

1. adopt the twin shaft design in the agitator, after aggregate added agitator, the motor-driven reducer drove main axis rotation by chain, relied on synchromesh gear to guarantee the rotation of twin shaft synchronous backward, had saved the space, had reduced cost of production.

2. the array mixing arm is housed on the twin shaft, and the arm end is equipped with the stirring blade of high-abrasive material, and stirring blade forms on axle and is interrupted the helix arrangement, material can be moved radially in stirring, can move axially again, have and stir, compact conformation, characteristics such as stirring efficiency height.

3. stirrer paddle after the stirrer paddle wearing and tearing, as long as unclamp bolt, just can be changed stirrer paddle by being bolted on the mixing arm easily, need not to change whole mixing arm.
