Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a low-carbon asphalt mixing device for bridge construction. Background Technology
[0002] A bridge is generally a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Low-carbon asphalt is required for paving bridges during construction.
[0003] As shown in the reference case "A Mobile Low-Carbon Asphalt Mixing Plant" (Announcement No. CN222390185U), after the asphalt heating box delivers the heated asphalt into the asphalt mixing tank, the aggregate feeding hopper delivers the aggregate into the asphalt mixing tank. The asphalt mixing tank then mixes the asphalt and aggregate. However, during the mixing process, the heated asphalt continuously cools down. Multiple flame nozzles are used to spray flames onto the asphalt during the mixing process, and the flame size is controllable to ensure that the asphalt is always at the optimal temperature for mixing, thus preventing the asphalt from becoming too viscous due to cooling and becoming difficult to mix.
[0004] According to the aforementioned references, in the above-mentioned device, when the asphalt is transported to the asphalt mixing tank and mixed with gravel, multiple burners ignite the natural gas in the burners through an igniter, causing the burners to spray fire into the asphalt mixing tank. The size of the flame is controllable, and the flame heats the asphalt inside the mixing tank, preventing the asphalt from cooling down during the mixing process and ensuring that the asphalt remains within the optimal temperature range. This prevents the asphalt from cooling down and becoming viscous, making it difficult to mix. However, when mixing low-carbon asphalt, the mixing effect of this device is not uniform enough, affecting the mixing effect of low-carbon asphalt and making it inconvenient to mix low-carbon asphalt evenly, thus reducing the effectiveness of the device. Utility Model Content
[0005] Therefore, it is necessary to provide a low-carbon asphalt mixing device for bridge construction to address the problem of inconvenience in uniformly mixing low-carbon asphalt.
[0006] The device includes a support frame, on the inner wall of which a mixing drum is mounted; a mixing mechanism, which can uniformly mix asphalt and improve the mixing effect of the device, is disposed on the inner wall of the mixing drum; wherein, the mixing mechanism includes a spiral blade fixedly connected to the inner wall of the mixing drum, and two spiral rods are rotatably connected to the inner wall of the mixing drum, the two spiral rods being interlaced and disposed at the axis of the spiral blades, and a heating component is disposed on the inner wall of the support frame.
[0007] In one embodiment, the stirring mechanism further includes a gear fixedly connected to one end of the auger, two gears meshing with each other, and the gear being rotatably connected to one end of the inner wall of the stirring drum.

[0010] In one embodiment, two fixing plates are fixedly connected to the other end of the inner wall of the stirring tank, and one end of the fixing plate is rotatably connected to the other end of the screw rod.

[0012] In one embodiment, several evenly arranged ball bearings are fixedly connected to both sides of the top of the mounting plate, and the ball bearings are in contact with the outer wall of the mixing cylinder. Beneficial effects
[0013] 1. The aforementioned low-carbon asphalt mixing device for bridge construction, during the mixing of asphalt in the mixing drum, the mixing drum mixes the asphalt through the rotation of the internal spiral blades.

[0027] The following is combined Figures 1-4 This invention describes a low-carbon asphalt mixing device for bridge construction.
[0028] In one embodiment, a low-carbon asphalt mixing device for bridge construction includes a support frame 100, with a mixing drum 200 mounted on the inner wall of the support frame 100; a mixing mechanism 300, which can uniformly mix asphalt and improve the mixing effect of the device, is disposed on the inner wall of the mixing drum 200; wherein, the mixing mechanism 300 includes a spiral blade 310 fixedly connected to the inner wall of the mixing drum 200, and two spiral rods 320 rotatably connected to the inner wall of the mixing drum 200, the two spiral rods 320 being interlaced and disposed at the axis of the spiral blade 310, and a heating component 370 is disposed on the inner wall of the support frame 100.
[0029] It should be noted that the low-carbon asphalt mixing plant consists of a mixing drum 200, support rollers, a feeding system, a drying and mixing system, a transmission system, and a control system. Asphalt and aggregate are placed inside the mixing drum 200. The control system drives a heating device to heat and dry the asphalt. The control system also drives the blades inside the mixing drum 200 to rotate. A connecting shaft is located at the other end of the mixing drum 200 for connecting to external equipment and positioning the drum. The rotation of the mixing drum 200 ensures thorough mixing of the asphalt. Two spiral rods inside the mixing drum 200... The servo motor 340 and two gears 330 work together to rotate, which can mix the asphalt in the mixing drum 200. The two screw rods 320 can optimize the mixing effect of the mixing drum 200 without affecting the normal operation of the low-carbon asphalt mixing device. The heating component 370 can heat the mixing drum 200 evenly. The multiple mounting plates 371 on the inner wall of the support frame 100 can be positioned around the mixing drum 200 through the cooperation of ball bearings 373, so that the mixing drum 200 can rotate stably without affecting the normal use of the device.
[0030] like Figure 2 and Figure 3 As shown, the stirring mechanism 300 also includes a gear 330 fixedly connected to one end of the screw rod 320. The two gears 330 mesh with each other. The gear 330 is rotatably connected to one end of the inner wall of the stirring drum 200. A servo motor 340 is installed at one end of the inner wall of the stirring drum 200. The output shaft of one end of the servo motor 340 is fixedly connected to one of the gears 330. Two temperature sensors 350 are installed at one end of the inner wall of the stirring drum 200. Two fixing plates 360 are fixedly connected to the other end of the inner wall of the stirring drum 200. One end of the fixing plate 360 is rotatably connected to the other end of the screw rod 320.
[0031] In this embodiment, when the asphalt is stirred, the servo motor 340 drives two gears 330 to mesh, which in turn drives two screw rods 320 to generate shearing force to crush and mix the asphalt. In conjunction with the screw blades 310, the mixing effect is improved. The temperature sensor 350 can monitor the temperature inside the mixing drum 200 in real time, which can improve the mixing effect of the low-carbon asphalt mixing device and improve the uniformity of asphalt mixing.
[0032] like Figure 4 As shown, the heating assembly 370 includes several mounting plates 371 that are evenly arranged and fixedly connected to the inner wall of the support frame 100. Two heating rods 372 are installed on the inner wall of the mounting plate 371. Several evenly arranged ball bearings 373 are fixedly connected to both sides of the top of the mounting plate 371. The ball bearings 373 are in contact with the outer wall of the stirring drum 200.
[0033] In this embodiment, when the mixing drum 200 rotates, the two heating rods 372 inside the mounting plate 371 are in contact with the mixing drum 200, which can heat the mixing drum 200. The mounting plate 371 contacts the mixing drum 200 through multiple ball bearings 373 on both sides of the top, which positions the mixing drum 200 and can improve the mixing effect of the mixing device on asphalt.
[0034] Working principle: When asphalt is placed in the mixing drum 200, the mixing drum 200, through the cooperation of the external toothed blocks and the electric motor, drives the spiral blades 310 to rotate and mix the asphalt. The control system drives the servo motor 340 to drive one gear 330 to mesh with the other gear 330. The two gears 330 drive the two spiral rods 320 to rotate and mix the asphalt. The control system then supplies power to the heating rod 372, so that the heating rod 372 can heat the mixing drum 200 evenly. The temperature inside the mixing drum 200 is monitored in real time by the temperature sensor 350.
[0035] It should be noted that the servo motor 340, temperature sensor 350 and heating rod 372 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs, and the specific power supply method can be selected according to the situation, which will not be elaborated here.
[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
