Description

Technical Field

[0001] This utility model belongs to the field of asphalt mixing technology, specifically relating to a mixing machine for SMA asphalt waterproofing material. Background Technology

[0002] SMA (Solid Moss Asphalt) is an asphalt mixture composed of asphalt, fiber stabilizer, mineral powder, and a small amount of fine aggregate, used to fill the gaps in the discontinuously graded coarse aggregate skeleton. It is characterized by a high content of coarse aggregate, high mineral powder content, a relatively large asphalt content, and a low content of intermediate-sized particles. The high coarse aggregate content allows for direct contact and interlocking between particle surfaces, forming a skeleton that directly bears the load. This skeleton exhibits low temperature sensitivity.

[0003] However, existing SMA asphalt mixers often lack the function of scraping the inner wall of the mixing drum. Asphalt adhering to the inner wall of the mixing drum is difficult to clean, making it inconvenient to use. In addition, some existing mixers have scrapers, but the scrapers are often not detachable, making it difficult to clean them. After long-term use, asphalt easily adheres to the scrapers, reducing their service life. Therefore, there is an urgent need for a mixer for SMA asphalt waterproofing materials to solve the above problems. Utility Model Content

[0013] 1. This SMA asphalt waterproofing material mixing machine is equipped with a mixing structure and a rotating structure. Pushing out the piston rod of the electric pusher opens the cover plate, allowing the asphalt raw material to be poured into the mixing drum. Pulling back the piston rod of the electric pusher locks the cover plate onto the mixing drum. Turning on motor one drives the mixing rod to rotate, thus mixing the raw material evenly. After mixing, pushing out the piston rod of the electric pusher again opens the cover plate, turning on motor two, which drives the rotating shaft to rotate. This causes the mixing drum and the rotating rod to rotate, tilting the mixing drum forward to pour out the asphalt. The mixing and rotating structures effectively mix the asphalt raw material and facilitate asphalt pouring, making operation convenient and quick, and improving mixing efficiency.

Both support rods 33 are fixedly connected to the top of the base 1. The scraping structure 4... Except for structure 4, which includes a rotating rod 42, the bottom of the mixing tank 31 is rotatably connected to the rotating rod 42. Limiting plates 43 are fixedly connected to both the left and right sides of the rotating rod 42. The rotating rod 42 and the limiting plates 43 are slidably connected to a fixed seat 44. Scrapers 45 are fixedly connected to both the left and right sides of the fixed seat 44. The rotating rod 42 and the fixed seat 44 are threadedly connected to fixing bolts 46.

The scraping structure 4 can scrape off the asphalt on the inner wall of the mixing tank 31 and can disassemble the fixed seat 44 to facilitate the cleaning of the scraper 45 and improve the service life of the scraper 45.

[0023] Furthermore, a motor 24 is fixedly connected to the top of the cover plate 23, and a stirring rod 25 is fixedly connected to the drive shaft of the motor 24. When the motor 24 is turned on, it drives the stirring rod 25 to rotate, thereby stirring the raw materials and making them evenly mixed.

[0024] Furthermore, the right side of the support rod 33 is fixedly connected to the rotating shaft 34, and the rotating shaft 34 is rotatably connected to the support rod 33. The right side of the support rod 33 is fixedly connected to the second motor 35, and the drive shaft of the second motor 35 is fixedly connected to the rotating shaft 34. When the second motor 35 is turned on, it drives the rotating shaft 34 to rotate, which in turn drives the mixing tank 31 and the rotating rod 32 to rotate, causing the mixing tank 31 to tilt forward and pour out the asphalt.

[0025] Furthermore, a motor 3 41 is fixedly connected to the bottom of the mixing tank 31, and the drive shaft of the motor 3 41 is fixedly connected to the rotating rod 2 42. When the motor 3 41 is turned on, the motor 3 41 drives the rotating rod 2 42 to rotate, which in turn drives the fixed base 44 to rotate.

The cover plate 47 covers and seals the fixing bolt 46 to prevent asphalt from seeping into the joint between the fixing bolt 46 and the fixing seat 44 during asphalt mixing, making it difficult to disassemble the fixing bolt 46.

[0029] Working principle: In use, push out the piston rod of the electric push rod 22 to open the cover plate 23, pour the asphalt raw material into the mixing drum 31, pull back the piston rod of the electric push rod 22 to lock the cover plate 23 onto the mixing drum 31, turn on the motor 24 to drive the mixing rod 25 to rotate, and stir the raw material to make it evenly mixed. After mixing, push out the piston rod of the electric push rod 22 again to open the cover plate 23, turn on the motor 35 to drive the rotating shaft 34 to rotate, and the rotating shaft 34 to drive the mixing drum 31 and the rotating rod 32 to rotate, causing the mixing drum 31 to tilt forward and pour out the asphalt. The mixing structure 2 and the rotating structure 3 can stir the asphalt raw material and facilitate the pouring out of the asphalt. The system is easy and quick to operate, improving mixing efficiency. When pouring out asphalt, turn on motor 3 (41), which drives rotating rod 2 (42) to rotate. Rotating rod 2 (42) drives fixed seat 44 to rotate, which in turn drives scraper 45 to scrape the inner wall of mixing drum 31, removing the asphalt adhering to the inner wall of rotating structure 3. When it is necessary to clean motor 2 (35), pull the lever 48, lift cover plate 2 (47), and remove fixing bolts 46 to remove fixed seat 44 and scraper 45 for cleaning. The scraping structure 4 can remove asphalt from the inner wall of mixing drum 31, and the fixed seat 44 can be disassembled for easy cleaning of scraper 45, thus improving the service life of scraper 45.
