Description

Technical Field

[0001] This utility model relates to the field of hot mixing recycling technology, specifically to an asphalt hot mixing recycling batching machine. Background Technology

[0002] Hot asphalt recycling involves excavating or milling old asphalt concrete pavement layers, collecting them at a mixing plant, and pre-treating them as needed, such as crushing and screening. A certain proportion of new aggregates, new asphalt, and recycling agents are then mixed in, heated and stirred using mixing equipment, and transported to the construction site to be paved to form a new asphalt concrete pavement structure layer with certain road performance characteristics.

[0003] Asphalt is typically mixed using a mixing rod. However, after mixing, due to its high viscosity, some asphalt easily sticks to the inner wall of the mixing drum during the pouring process. Once the asphalt hardens, manual cleaning is required for future use, which is time-consuming, labor-intensive, and reduces the efficiency of subsequent road paving. Therefore, there is an urgent need to design an asphalt hot mixing and recycling batching machine to solve these problems. Utility Model Content

[0027] A hollow shaft 9 is installed on the upper side of the frame 6. The hollow shaft 9 is connected to the frame 6. A push block assembly corresponding to two sliders 8 is slidably fitted inside the hollow shaft 9. A discharge port 10 is opened on the lower side of the barrel 3. A collection box 11 corresponding to the discharge port 10 is slidably fitted on the upper side of the bottom plate 1. A scraper cover 12 is slidably fitted inside the barrel 3.

[0028] In this embodiment, the base plate 1;

[0029] Specifically, a power supply body 25 connected to the heating wire 5 is installed on the upper side of the base plate 1. A groove 26 is opened on the upper side of the base plate 1. The collection box 11 is slidably fitted in the groove 26, and one of its transmission pipes 24 corresponds to the collection box 11. Through the collection box 11, the mixed asphalt can be collected and stored, reducing the workload of the staff later.

[0030] In this embodiment, a support frame 2 is installed on the upper side of the base plate 1, and a barrel 3 is installed above the support frame 2.

[0031] Specifically, two feeding ports 23 are symmetrically opened on the periphery of the barrel 3. The two feeding ports 23 are located between the gap and the annular groove 4. Valves are provided at both feeding ports 23 and the discharge port 10. One end of each of the multiple valves is equipped with a transmission pipe 24. Through one of the transmission pipes 24, the mixed asphalt can be transferred to the collection box 11 for collection and storage.

[0032] In this embodiment, an annular groove 4 is provided inside the barrel 3, and a heating wire 5 is installed in the annular groove 4. A frame 6 is rotatably fitted inside the barrel 3. L-shaped rods 7 are slidably fitted at the middle of both ends of the frame 6, and sliders 8 are installed at the opposite ends of the two L-shaped rods 7.

[0033] Specifically, each of the two sliders 8 has an inclined surface on one side, and the trapezoidal block 15 corresponds to the two inclined surfaces. Two grooves 16 are symmetrically opened at the bottom of the frame 6. The sliders 8 slide in the grooves 16. The first cylinder 13 causes the push rod 14 to move the trapezoidal block 15 downward, so that the trapezoidal block 15 squeezes the two sliders 8, causing the two L-shaped rods 7 to extend out of both ends of the frame 6 at the same time, thus preparing for the next step of scraping off the asphalt adhering to the inner wall of the barrel 3.

[0034] Specifically, springs 17 are installed on the inner side of both slides 16. One end of each spring 17 is fixedly connected to the two sliders 8, and the hollow shaft 9 is rotatably fitted to the upper side of the barrel 3. Through the springs 17, the two L-shaped rods 7 can be driven to automatically return to their original positions.

[0035] In this embodiment, two sliders 8 are slidably engaged at the bottom of the frame 6, and a hollow shaft 9 is installed on the upper side of the frame 6.

[0036] Specifically, a first bevel gear 18 is installed on the periphery of the hollow shaft 9, and a second bevel gear 19 that meshes with the first bevel gear 18 is rotatably fitted inside the upper side of the barrel 3. A motor 20 and a second cylinder 21 are installed on the upper side of the barrel 3. The output end of the motor 20 is fixedly connected to the shaft of the second bevel gear 19. The motor 20 can drive the second bevel gear 19 to rotate, so that the second bevel gear 19 meshes with the first bevel gear 18 and rotates, thereby driving the hollow shaft 9 to rotate, in preparation for the next step of mixing and stirring the asphalt recycling agent and the old asphalt.

[0037] In this embodiment, the hollow shaft 9 is connected to the frame 6, and a push block assembly corresponding to the two sliders 8 is slidably fitted inside the hollow shaft 9.

[0038] Specifically, the push block assembly includes a first cylinder 13 mounted on the upper end of the hollow shaft 9, a push rod 14 mounted on the output end of the first cylinder 13, and a trapezoidal block 15 mounted on the lower end of the push rod 14. The push rod 14 is slidably fitted to the inner side of the hollow shaft 9.

[0039] In this embodiment, a discharge port 10 is provided on the lower side of the barrel body 3, a collection box 11 corresponding to the discharge port 10 is slidably fitted on the upper side of the bottom plate 1, and a scraper cover 12 is slidably fitted inside the barrel body 3.

[0040] Specifically, the scraper cover 12 has an opening 22 in the middle that corresponds to the frame 6. The output end of the second cylinder 21 is fixedly connected to the upper side of the scraper cover 12. A gap is left between the frame 6 and the top of the barrel 3. The scraper cover 12 is located in the gap. The second cylinder 21 can drive the scraper cover 12 to move downward, thereby scraping off the asphalt adhering to the inner wall of the barrel 3 again.

[0041] Working steps: 1. When hot mixing and recycling of asphalt is required, first open the two valves at the two feed ports 23, and introduce the old asphalt and asphalt recycling agent into the barrel 3 through the two transmission pipes 24. Then start the power supply body 25 and motor 20. At this time, the output end of the power supply body 25 drives the heating wire 5 to generate heat and heat the inside of the barrel 3. At the same time, the output end of the motor 20 drives the second bevel gear 19 to rotate, so that the second bevel gear 19 meshes with the first bevel gear 18 and rotates, thereby driving the hollow shaft 9 to rotate. The hollow shaft 9 drives the frame 6 and the two L-shaped rods 7 to rotate synchronously, thereby heating and stirring the old asphalt and asphalt recycling agent and mixing them evenly. At this time, the asphalt recycling agent reacts chemically with the components in the old asphalt, which can increase the flexibility and adhesion of the old asphalt, and realize the hot mixing and recycling of old asphalt.

[0042] 2. When it is necessary to scrape off the asphalt adhering to the inner wall of the barrel 3, the first cylinder 13 is activated. The output end of the first cylinder 13 drives the push rod 14 to move downward. At this time, the trapezoidal block 15 squeezes the two sliders 8, causing the two sliders 8 to drive the two L-shaped rods 7 to extend out of both ends of the frame 6 simultaneously. Thus, the two L-shaped rods 7 slide and engage with the frame 6. At this time, the two L-shaped rods 7 are in contact with the inner wall of the barrel 3. At this time, the two sliders 8 slide and engage in the two sliding grooves 16. At the same time, the two springs 17 elastically extend and retract. Then, the hollow shaft 9 is activated. At this time, the hollow shaft 9 drives the two adjusted L-shaped rods 7 to rotate synchronously. Thus, the two L-shaped rods 7 scrape off the asphalt adhering to the inner wall of the barrel 3. After the scraping is completed, the second cylinder 21 is activated. The output end of the second cylinder 21 drives the scraper cover 12 to move downward, so that the scraper cover 12 scrapes off the inner wall of the barrel 3 again, thus realizing the scraping work of the inner wall of the barrel 3.

[0043] 3. When it is necessary to collect the hot-mix recycled asphalt, open the valve at the discharge port 10. At this time, the mixed asphalt is introduced into the collection box 11 through a transmission pipe 24 for collection, thereby realizing the collection and storage of hot-mix recycled asphalt.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
