[0030] Example 1

[0031] See also Figure 1 This embodiment provides an asphalt mixing device to solve the problem that when the existing mixing mechanism mixes and stirs the asphalt mixture, the material will stick to the inner wall of the cylinder.

[0032] In this embodiment, the asphalt mixing device includes a cylinder 10 in which a rotating shaft 20 with stirring blades 21 is provided. The rotating shaft 20 is transmission-connected to a motor 24 arranged at the top of the cylinder 10. A connecting plate 22 of a closed-loop structure is fixedly connected to the outer end of the stirring blade 21. A coaxially arranged scraper ring 30 is adhered to the inner wall of the cylinder 10. A pin 31 slidingly engaged with a guide groove 23 formed on the outer wall of the connecting plate 22 is fixedly connected to the inner wall of the scraper ring 30. The guide groove 23 is configured so that the connecting plate 22 can drive the scraper ring 30 to reciprocate along the axial direction of the cylinder 10 by following the synchronous rotation of the rotating shaft 20.

[0033] This embodiment utilizes the sliding engagement between the pin 31 and the guide groove 23, so that the connecting plate 22 can also drive the scraper ring 30 to move up and down while rotating synchronously with the rotating shaft 20, thereby achieving the purpose of cleaning the cylinder wall during the mixing process and preventing the material from sticking to the cylinder wall.

[0034] It should be noted that the cylinder 10 as a whole is constructed as a circular structure with an open top, and a discharge port 12 is provided at the bottom of the cylinder 10. When the asphalt mixture is stirred, the discharge port 12 is in a closed state; a support beam 11 is fixedly connected to the top of the cylinder 10, and the support beam 11 is arranged along the diameter direction of the cylinder 10. The motor 24 is fixedly connected to the support beam 11. The rotating shaft 20 is fixedly connected to the output shaft of the motor 24 after passing through the support beam 11, and the motor 24 is used to drive the rotating shaft 20 to rotate; a plurality of limit strips 13 are fixedly connected to the inner wall of the cylinder 10, and the limit strips 13 are arranged parallel to the axis of the cylinder 10, and the plurality of limit strips 13 are evenly distributed along the circumference of the cylinder 10.

[0035] In addition, the rotating shaft 20 is coaxially arranged with the cylinder 10, the stirring blade 21 is fixedly connected to the rotating shaft 20, the stirring blade 21 is vertically arranged with the rotating shaft 20, and the stirring blade 21 is evenly distributed along the circumference of the rotating shaft 20. At the same time, the stirring blade 21 is evenly spaced along the axial direction of the rotating shaft 20; the connecting plate 22 is a closed-loop structure as a whole, the connecting plate 22 is fixedly connected to the outer end of the stirring blade 21, and the connecting plate 22 is tilted relative to the rotating shaft 20 as a whole. The outer wall of the connecting plate 22 is located on the same circumferential surface coaxially arranged with the rotating shaft 20, and the guide groove 23 is formed on the outer wall of the connecting plate 22, and the guide groove 23 extends along the extension direction of the connecting plate 22.

[0036] In addition, the scraper ring 30 is constructed in a circular ring shape coaxially arranged with the cylinder 10, and the outer wall of the scraper ring 30 is in contact with the inner wall of the cylinder 10. A slot for engaging with the limit strip 13 is provided on the outer wall of the scraper ring 30. The sliding engagement between the slot and the limit strip 13 allows the scraper ring 30 to only move axially along the cylinder 10. The pin 31 is fixed to the inner wall of the scraper ring 30, and the pin 31 is arranged radially along the cylinder 10. The outer end of the pin 31 can be slidably engaged with the inside of the guide groove 23. When the guide groove 23 rotates with the rotating shaft 20, it will drive the scraper ring 30 to slide along the limit strip 13, thereby cleaning the inner wall of the cylinder 10 and preventing the asphalt mixture from sticking to the inner wall.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
