For example, the plurality of diversion mechanisms 30 can be 2, 3, 4, 5, 6 diversion mechanisms 30, etc. The specific number of diversion mechanisms 30 can be selected according to actual conditions and is not limited here.

[0024] The driving assembly 40 is mounted on the support frame 10, and the driving assembly 40 is respectively connected to the plurality of diversion mechanisms 30. The heating box 50 is arranged on the plurality of diversion mechanisms 30, and the heating box 50 is respectively connected to the plurality of diversion mechanisms 30, and the top of the heating box 50 passes through the insulation box 20, and the top of the heating box 50 is provided with a feed port 501, and the bottom of the heating box 50 is provided with a discharge pipe 502 passing through the insulation box 20. It should be noted that the discharge pipe 502 described in this embodiment is provided with a valve for controlling the discharge of the mixture (modifier and asphalt mixture).

[0025] The plurality of heating mechanisms 60 are respectively connected to the heating box 50 and the corresponding diverting mechanism 30, the stirring mechanism 70 is rotatably disposed in the heating box 50, the driving mechanism 80 is disposed on the heating box 50, and the output end of the driving mechanism 80 is connected to the stirring mechanism 70. It should be noted that the number of the plurality of heating mechanisms 60 described in this embodiment is equal to the sum of the plurality of diverting mechanisms 30 and the heating box 50.

[0026] It should be noted that the driving mechanism 80 described in this embodiment may be a driving motor.

[0027] In the embodiment of the present invention, the heating mechanism 60 may be a heating wire, and a plurality of heating wires are respectively wound around the heating box 50 and the outer wall of the corresponding shunt cylinder 31 , and the plurality of heating wires are respectively electrically connected to an external power source.

[0028] Specifically, when the modifier and asphalt in a solid state need to be melted and fused together, the staff can put the solid granular asphalt and modifier into the heating box 50 through the feed port 501, and then the staff can connect the heating mechanism 60 to an external power source to heat the heating box 50 and the multiple diversion mechanisms 30 through the heating mechanism 60.

[0029] During the heating process, the staff can control the driving mechanism 80 to drive the stirring mechanism 70 to rotate, stir the granular asphalt and modifier to make them evenly mixed. At the same time, the staff controls the driving component 40 to drive multiple diversion mechanisms 30 to divert and heat the asphalt and modifier located in the heating box 50, so that the granular asphalt and modifier flow back and forth between the heating box 50 and the diversion mechanism 30. This not only allows the asphalt and modifier to be heated evenly and accelerates the melting speed, but also allows the melted asphalt and modifier to be quickly and fully mixed together. It has the advantages of easy operation, time saving and labor saving, and can effectively improve the mixing efficiency.

[0030] When the mixing is completed, the staff can discharge the fully mixed mixture (mixture of asphalt and modifier) ​​from the heating box 50 by opening the valve on the discharge pipe 502 .

[0031] In one embodiment of the present invention, Figure 3 As shown, the flow dividing mechanism 30 may include a flow dividing cylinder 31, a piston 32 and a guide rod 33, wherein the flow dividing cylinder 31 is vertically fixedly arranged on the bottom wall of the inner cavity of the heat preservation box 20. The top end of the flow dividing cylinder 31 is fixedly connected to the bottom wall of the heating box 50, and the flow dividing cylinder 31 is connected to the heating box 50, and the piston 32 is movably arranged in the flow dividing cylinder 31.

[0032] It should be noted that the initial state of the piston 32 described in this embodiment is a state in which the top wall of the piston 32 is flush with the bottom wall of the inner cavity of the heating box 50 (in the same plane).

[0033] One end of the guide rod 33 is fixedly connected to the piston 32 , and the other end of the guide rod 33 passes through the diversion cylinder 31 and the heat preservation box 20 in sequence and extends to the bottom of the heat preservation box 20 .

[0034] Further, in one embodiment of the present invention, Figure 1-Figure 3 As shown, the driving assembly 40 may include a support plate 41 and a retractable mechanism 42 , wherein the top wall of the support plate 41 is fixedly connected to the other end of the guide rod 33 .

[0035] The retractable mechanism 42 is mounted on the support frame 10, and the output end of the retractable mechanism 42 is fixedly connected to the bottom wall of the support plate 41. It should be noted that the initial state of the output end of the retractable mechanism 42 described in this embodiment is an extended state.

[0036] It should be noted that the retractable mechanism 42 described in this embodiment may be a cylinder, a hydraulic cylinder or an electric retractable rod.

[0037] Further, in one embodiment of the present invention, Figure 3 As shown, the stirring mechanism 70 may include a support shaft 71 and a plurality of stirring blades 72 , wherein the support shaft 71 is vertically and rotatably arranged in the heating box 50 , and the top end of the support shaft 71 passes through the heating box 50 and is connected to the output end of the driving mechanism 80 .

[0040] Specifically, when it is necessary to make the asphalt and the modifier in the heating box 50 melt quickly and mix them fully, the staff can control the driving mechanism 80 to drive the support shaft 71 to drive the multiple stirring blades 72 to rotate in the heating box 50 to fully stir the asphalt and the modifier. At the same time, the staff controls the output end of the telescopic mechanism 42 to retract and extend reciprocatingly. As the output end of the telescopic mechanism 42 retracts and extends, the support plate 41 is driven to move up and down. The support plate 41 that moves up and down drives the piston 32 to move up and down through the guide rod 33. The piston 32 that moves up and down repeatedly draws the asphalt and the modifier into the diverter tube 31 for dispersed heating, so that the asphalt and the modifier are evenly heated, thereby accelerating the melting speed of the asphalt and the modifier.

[0041] When the asphalt and the modifier are melted, with the stirring of the stirring blade 72 and the reciprocating movement of the piston 32, the melted asphalt and the modifier can be stirred and mixed while flowing between the heating box 50 and the diverter cylinder 31, effectively improving the mixing efficiency of the asphalt and the modifier.
