It addresses the problem in existing technologies where, during the mixing process of modified asphalt raw materials, the raw materials need to be fed into the mixing tank through the inlet. Due to the poor fluidity of asphalt raw materials, blockages easily occur at the inlet, requiring manual unblocking and affecting production efficiency.

[0025] Please see Figures 1 to 5The present invention will describe the above technical solution in detail through the following embodiments:

[0026] A vertical modified asphalt raw material mixing device includes: a mixing chamber 1; an inlet 2 is provided on one side of the top of the mixing chamber 1, and an outlet 3 is provided at the center of the bottom of the mixing chamber 1; a gearbox 4 is fixedly connected to the side of the mixing chamber 1 away from the inlet 2; a hollow tube 5 is provided at the center of the top of the mixing chamber 1; an insulation box 6 is fixedly connected to the outer surface of the mixing chamber 1; a motor frame 7 is fixedly connected to the top of the gearbox 4; a fixing ring 8 is fixedly connected to the outer surface of the insulation box 6; and support frames 9 are fixedly connected to the four corners of the bottom of the fixing ring 8; a stirring mechanism 10 is provided on the outer surface of the hollow tube 5 located inside the mixing chamber 1 to improve the mixing effect of the asphalt raw materials; and a discharge mechanism 11 is provided on one side of the top of the motor frame 7 to control the rapid discharge of the mixed asphalt raw materials. The user pours the modified asphalt raw materials into the device through the inlet 2. While the device heats the modified asphalt raw materials, it also stirs and mixes the modified asphalt raw materials through the stirring mechanism 10. The user can also discharge the mixed modified asphalt to the outside of the device through the outlet 3 via the discharge mechanism 11.

[0027] like Figure 3 As shown, the stirring mechanism 10 includes: a hollow tube 5 located inside the mixing chamber 1 with four sets of stirring blades 12 fixedly connected to its outer surface; the top end of the hollow tube 5 penetrates the mixing chamber 1 and extends to the rotating sleeve 13; the hollow tube 5 and the rotating sleeve 13 are slidably connected; the rotating sleeve 13 is rotatably connected to the gearbox 4; a first gear 14 is fixedly connected to the bottom outer surface of the rotating sleeve 13; a second gear 15 meshes with one side of the first gear 14; a worm 16 is fixedly connected to the center of the second gear 15; a fixing block 17 is rotatably connected to the bottom end of the worm 16; the fixing block 17 is fixedly connected to the gearbox 4; and the top end of the worm 16 penetrates the mixing chamber 1. The gearbox 4 extends to the first motor 18, which is fixedly connected to the gearbox 4. The worm gear 16 is fixedly connected to the output end of the first motor 18. When the first motor 18 is started, its output end drives the worm gear 16. The worm gear 16 rotates with the cooperation of the fixed block 17. While the worm gear 16 rotates, it drives the second gear 15. The second gear 15 drives the first gear 14. The first gear 14 drives the rotating sleeve 13. While the rotating sleeve 13 rotates inside the gearbox 4, it drives the hollow tube 5 to rotate. While the hollow tube 5 rotates, it drives the stirring blade 12, thereby controlling the stirring blade 12 to rotate.

[0028] like Figure 3 and Figure 4As shown, a worm gear 16 is meshed with a worm wheel 19 on one side. A first rotating shaft 20 is rotatably connected to the center of the worm wheel 19. The end of the first rotating shaft 20 away from the worm wheel 19 is fixedly connected to the gearbox 4. A first rotating block 21 is fixedly connected to the side of the worm wheel 19 away from the first rotating shaft 20. A linkage rod 22 is rotatably connected to one side of the first rotating block 21. A second rotating block 23 is rotatably connected to the other end of the linkage rod 22. A third gear 24 is fixedly connected to the end of the second rotating block 23 away from the linkage rod 22. A second rotating shaft 25 is rotatably connected to the center of the third gear 24. The end of the second rotating shaft 25 away from the third gear 24 is fixedly connected to the gearbox 4. Several toothed rings 26 are fixedly connected to the outer surface of the hollow tube 5 near the third gear 24. Ring 26 meshes with third gear 24. While worm 16 rotates, it also drives worm wheel 19. Worm wheel 19 rotates through the cooperation of first rotating shaft 20. While rotating, worm wheel 19 drives first rotating block 21. While rotating, first rotating block 21 drives one end of linkage rod 22 to rotate, causing the other end of linkage rod 22 to pull second rotating block 23. Second rotating block 23 drives third gear 24 to continuously perform semi-circular reciprocating rotation. While rotating, third gear 24 drives hollow tube 5 through ring teeth. Hollow tube 5 continuously performs reciprocating lifting and lowering motion through the cooperation of rotating sleeve 13. While lifting and lowering, hollow tube 5 drives stirring blade 12, so that stirring blade 12 can also perform reciprocating lifting and lowering motion while rotating.

[0029] like Figure 5 As shown, six limiting slide bars 27 are evenly fixedly connected to the outer surface of the hollow tube 5 near the rotating sleeve 13. The hollow tube 5 is slidably connected to the rotating sleeve 13 through the limiting slide bars 27. Not only can the hollow tube 5 rotate by the limiting slide bars 27 while the rotating sleeve 13 is rotating, but the limiting slide bars 27 can also flexibly slide up and down inside the rotating sleeve 13 while the hollow tube 5 is rising and falling.

[0030] like Figure 2 As shown, the discharge mechanism 11 includes: a second motor 28 fixedly connected to one side of the top of the motor frame 7; a transmission shaft 29 fixedly connected to the output end of the second motor 28; the bottom end of the transmission shaft 29 passes through the hollow tube 5 and extends into the interior of the discharge port 3; an auger blade 30 is fixedly connected to the outer surface of the transmission shaft 29 located inside the discharge port 3; the auger blade 30 is adapted to the discharge port 3; when the second motor 28 is started, the output end of the second motor 28 drives the transmission shaft 29 to rotate; while the transmission shaft 29 rotates, it drives the auger blade 30; the auger blade 30, through the cooperation of the discharge port 3, pushes the mixed modified asphalt out of the discharge port 3 at a uniform speed, achieving the function of quantitative discharge.

[0031] like Figure 2As shown, a spiral heating tube 31 is fixedly connected inside the insulation box 6, and a temperature sensor 32 is fixedly connected to the top inner wall of the mixing box 1. A control box 33 with an internal touch screen is fixedly connected to one side of the insulation box 6. The temperature sensor 32 can monitor the temperature inside the mixing box 1 in real time. When the temperature inside the mixing box 1 is lower than the set minimum threshold, the heating tube 31 is activated through the control box 33. The heating tube 31 heats the modified asphalt raw material through the mixing box 1, thereby improving the fluidity of the modified asphalt raw material by heating.

[0032] like Figure 1 As shown, two structural plates 34 are provided on both sides of the motor frame 7. The structural plates 34 are fixedly connected to the motor frame 7, the gearbox 4 and the mixing box 1, which improves the structural strength of the connection between the motor frame 7, the gearbox 4 and the mixing box 1.

[0033] Working principle: The user pours the modified asphalt raw material into the device through the inlet 2, and then starts the first motor 18. The output end of the first motor 18 drives the worm gear 16. The worm gear 16 rotates through the cooperation of the fixed block 17. While the worm gear 16 rotates, it drives the second gear 15. The second gear 15 drives the first gear 14. The first gear 14 drives the rotating sleeve 13. While the rotating sleeve 13 rotates inside the gearbox 4, it drives the hollow tube 5 to rotate. While the hollow tube 5 rotates, it drives the stirring blade 12, thereby controlling the rotation of the stirring blade 12. While the worm gear 16 rotates, it also drives the worm wheel 19. The worm wheel 19 rotates through the cooperation of the first rotating shaft 20. While the worm wheel 19 rotates, it drives the first rotating block 21. While the first rotating block 21 rotates, it drives one end of the linkage rod 22 to rotate, so that the other end of the linkage rod 22 pulls the second rotating block 23. The second rotating block 23 drives the third gear 24 to continuously reciprocate in a semi-circular arc. While the third gear 24 rotates, it drives the hollow tube 5 through the ring gear. The hollow tube 5, in cooperation with the rotating sleeve 13, continuously reciprocates and moves up and down. While the hollow tube 5 moves up and down, it drives the stirring blade 12, so that the stirring blade 12 can also continuously reciprocate and move up and down while rotating. This not only increases the stirring range of the modified asphalt raw materials, but also heats the modified asphalt raw materials, thereby increasing the fluidity of the asphalt raw materials and improving the mixing efficiency of the asphalt raw materials. This solves the problem that although the existing vertical modified asphalt raw material mixing device can stir and mix the modified asphalt raw materials, its internal stirring plate does not have the function of reciprocating and moving up and down while stirring the modified asphalt raw materials, and the stirring range is relatively limited, resulting in poor mixing efficiency of the modified asphalt raw materials.

[0034] The second motor 28 is started, and the output end of the second motor 28 drives the transmission shaft 29 to rotate. While the transmission shaft 29 rotates, it drives the auger blades 30. The auger blades 30, in cooperation with the discharge port 3, push the mixed modified asphalt out of the discharge port 3 at a uniform speed, achieving the function of quantitative discharge. This not only allows the mixed modified asphalt raw materials to be quickly discharged to the outside of the device, but also controls the quantitative discharge of the mixed modified asphalt raw materials, thereby improving the practicality of the device.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
