Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and in particular to an asphalt mixing equipment for highway construction. Background Technology

[0002] In the construction of asphalt pavement, asphalt mortar mixing equipment is needed to mix the raw materials of asphalt mortar to ensure thorough mixing. Generally, large-scale production is carried out at asphalt mortar mixing plants, which can greatly improve the production efficiency of asphalt mortar.

[0003] However, existing asphalt mortar mixing equipment is generally suitable for large-scale highway construction projects. It is not very adaptable to repairing small-area damaged pavements on narrow roads or pavements with scattered damage points, such as roads inside residential areas or relatively narrow non-motorized vehicle lanes. It is difficult to meet the actual construction needs and is not very convenient to use.

[0004] To address the aforementioned issues, a search revealed an existing patent (application number: CN202323070372.5) for an asphalt mortar mixing device for highway construction. The patent describes the device as "comprising: a housing with a top cover and a feeding hopper on the top cover; a discharge port at the bottom of the housing with an electric valve inside the discharge port; a mixing mechanism for mixing asphalt mortar raw materials, the mixing mechanism being mounted on the housing; and an auger conveyor for conveying the asphalt mortar, the auger conveyor being mounted on the discharge port of the housing."

[0005] While the equipment can mix the asphalt mortar raw materials and accurately drop them into the potholes when repairing small damaged areas on narrow roads, the viscous nature of the asphalt mortar makes it prone to adhering to the container. Even with mixing and conveying by an auger, uneven discharge can still occur, affecting the construction effect. Therefore, an asphalt mixing equipment for highway construction is proposed.

Then, the first motor 201 is started, driving the drive shaft 202 to rotate. The drive shaft 202 drives the first gear 203 to rotate, which in turn drives the mixing tank 101 to rotate on the mounting plate 1 via the gear ring 204. Simultaneously, the drive shaft 202 rotates, driving the second gear 205 to rotate. The second gear 205 drives the third gear 206 to rotate on the mounting plate 1, which in turn drives the mixing shaft 208 to rotate via the fourth gear 207. This causes the mixing blades 209 to rotate in the opposite direction to the mixing tank 101, thoroughly mixing the asphalt raw material inside. Furthermore, the scraper 210 removes any adhering asphalt. Asphalt is scraped off the inner wall of the mixing drum 101. When unloading is required for construction, hold the handle 5 and push the device to move through the casters 6. Then start the second motor 501 to drive the second threaded rod 502 to rotate, so that the threaded block 503 slides in the groove 505 toward the auger conveyor 4. Then, the connecting rod 504 drives the mounting plate 1 to rotate on the base plate 3. Next, start the auger conveyor 4. Finally, manually turn the handle 405 to drive the first threaded rod 402 to rotate, so that the baffle 403 slides on the limiting plate 404 toward the handle 405. The asphalt that has been mixed in the mixing drum 101 falls into the auger conveyor 4 through the discharge port 102 and the feeding port 103 and is conveyed outward.
