The utlity model has following beneficial effect:
The cold asphalt rehabilitation continuous mixer that the utility model provides is compared with existing mixer, the stirring vane connection and reasonable arrangement of mixing plant, can make the compound being stirred form the motion blendings such as violent convection current, shearing, rolling, produce the mixing effect of multidimensional, make the even mixing of difficulty action accomplishment in the compound short time.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of Fig. 1, removes top cover so that internal construction to be shown.
Fig. 3 is the two shafts structural representations at visual angle vertically.
Detailed description of the invention
Shown in Fig. 1, Fig. 2 and Fig. 3, a kind of continuous mixer for cold asphalt rehabilitation, comprise agitator 1, be rotationally arranged in parallel two shafts 3 in agitator, connect the drive unit 2 that drives two shafts 3 to rotate, agitator 1 left end top is provided with charging aperture 11, right-hand member below is provided with discharging opening 12.
On shaft 3, be arranged at intervals with multiple agitating units, each agitating unit comprises that circumference is arranged on four mixing arms 41 on shaft 3 and is arranged on the stirring vane 42 on mixing arm 41, mixing arm 41 is along the radially extension of shaft 3, agitating unit comprises eight forward agitating unit 4a that stirring vane 42 forwards are arranged, stirring vane 42 reversed arrangement and be arranged on a first reverse agitating function unit 4b of shaft 3 medium positions, stirring vane 42 reversed arrangement and be arranged on a second reverse agitating function unit 4c of shaft 3 tail ends, spacing between adjacent two forward agitating unit 4a equates, spacing between the adjacent forward agitating unit 4a in the first reverse agitating function unit 4b and left side is 2 times of adjacent two forward agitating unit 4a spacing, spacing between the adjacent forward agitating unit 4a on the first reverse agitating function unit 4b and right side is zero, spacing between the adjacent forward agitating unit 4a in the second reverse agitating function unit 4c and left side is 5 times of adjacent two forward agitating unit 4a spacing, center to center distance between two shafts is 1.6 times of the agitating unit radius of gyration, stirring vane is and the vertically arranged microscler plate body of mixing arm that the angle of the relative shaft axis of acting surface of stirring vane is 45 degree.
