The conductive asphalt mixing and paving device can be additionally installed on the basis of the traditional asphalt paving vehicle.

Referring to fig. 1-5, the conductive asphalt mixing and paving device of the present invention comprises a blanking body for conductive media and a stirring body for mixing the conductive media and asphalt, wherein the conductive media is steel slag. The blanking main body of the conductive medium comprises a filling device and a screen device, a through hole for blanking the conductive medium is formed in a bottom plate 5 of a filling box of the filling device, a screen hole 8 is formed in a screen disc 7 of the screen device, the screen device controls the screen disc 7 to move relative to the bottom plate 5 of the filling box through a screen motor 6, when the through hole in the bottom plate 5 of the filling box is superposed with the screen hole in the screen disc 7, the conductive medium enters a receiving funnel 16 and is conveyed to the middle of a stirring box shell 9 by a scraper conveyer 15 through the receiving funnel 16. The stuffing box housing 4 of the stuffing device corresponds to the width of the receiving funnel 16, the length of the stuffing box housing is one fourth of the length of the receiving funnel 16, the receiving funnel 16 is in an inverted trapezoid shape, and the width of the bottom surface of the stuffing box housing corresponds to the width of the scraper conveyer 15.

The stirring main body comprises a stirring shaft 13 with stirring blades 14, the stirring shaft 13 is fixed in the stirring box shell 9 through a bearing, and the stirring shaft 13 is connected with a stirring power mechanism. The stirring power mechanism comprises a stirring motor 10 and a speed reducer 11 for reducing the rotating speed of the motor and improving the output torque. Two stirring shafts 13 are arranged in the stirring box shell 9 in parallel, the two stirring shafts 13 are driven by two identical transmission gears 12, the two transmission gears 12 are meshed, and the rotating directions of the two stirring shafts 13 are opposite. The stirring blades 14 on the two stirring shafts 13 are regularly arranged and fixed on the stirring shafts 13 in a welding mode.

The screen cloth device includes the crank connecting rod, and the crank connecting rod includes one-level crank connecting rod 1 and second grade crank connecting rod 2, and the one end of one-level crank connecting rod 1 passes through reduction gear 11 and connects screen cloth motor 6, and the other end is articulated with the one end of second grade crank connecting rod 2, and the other end of second grade crank connecting rod 2 passes through hinge pin 3 and connects screen cloth dish 7. The coincidence time of the sieve holes 8 on the sieve tray 7 and the through holes on the bottom plate 5 of the stuffing box is adjusted by adjusting the rotating speed of the sieve motor 6, so that the falling speed of the conductive medium is adjusted.

The working principle of the invention is as follows:

1) the receiving hopper 16 receives asphalt concrete on the dump truck, and the screen motor 6 starts to rotate to drive the first-stage crank connecting rod 1 to move, further drive the second-stage crank connecting rod 2 to move, and finally drive the screen 7 to move.

The periodic reciprocating movement of the sieve screen 8 relative to the bottom plate 5 is realized by a crank-link mechanism.

2) When the sieve pores 8 coincide with the through holes on the bottom plate 5 of the stuffing box, the steel slag falls onto the asphalt concrete and is conveyed forwards together with the asphalt through the scraper conveyor 15; the friction between the screen and the steel slag and the reciprocating motion of the screen accelerate the falling speed of the steel slag on the screen, the rotating speed of the screen motor 6 is adjusted, the falling speed of the steel slag can be adjusted, and the generation of road surface raw materials with different proportions is realized by combining the feeding speed of asphalt.

3) In the aspect of the stirring function, when the asphalt material with the steel slag is conveyed to the lower part of the cab through the scraper conveyor 15, namely the position of the stirring part of the invention, the stirring motor 10 rotates to drive the speed reducer 11 to rotate, the speed reducer 11 reduces the rotating speed to a reasonable rotating speed and transmits power to the stirring shaft 13 through the transmission gear 12, the stirring shaft 13 rotates to drive the stirring blade 14 to rotate, and the asphalt concrete and the steel slag are uniformly stirred and mixed, so that the mixing of the conductive asphalt concrete is realized.

By adjusting the rotational speed of the motor 10, the mixing time can be controlled.

4) The generated conductive asphalt concrete is continuously transported by the scraper transporter 15 to the paving mechanism at the front end, and finally, the paving is realized by the paving mechanism.

5) After the asphalt mixture in one dumper is paved, the dumper leaves the material loading automatically, the other dumper full of material replaces the position of the dumper, and the operation is repeated to achieve continuous paving of the conductive road surface.
