Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt pavement repair, and more specifically, it particularly relates to a secondary stirring device for cold recycling of emulsified asphalt. Background Art

[0002] Emulsified asphalt is widely used in the repair and maintenance of roads. It can be used as a bonding layer or repair material to effectively repair damages such as pavement cracks and potholes, and also helps to enhance the bonding force between layers of the pavement, improving the overall stability of the road. In cold winter seasons or after long-term storage, emulsified asphalt may experience stratification. At this time, secondary stirring through cold recycling is required to ensure the usage effect. Existing secondary stirring devices for cold recycling of emulsified asphalt generally consist of a base, a stirring barrel, a stirring motor, and stirring components.

[0003] The existing application number: CN201921641131.2. The utility model relates to the field of asphalt mixing devices and discloses an emulsified asphalt mixing device, including a base. A tank body is provided inside the base. One end of the tank body extending upward is provided with a feed inlet, and one end of the tank body extending downward is provided with a discharging device. One end of the tank body extending upward is fixedly provided with a driving device. The extending end of the driving device is provided with a rotating shaft penetrating into the inner cavity of the tank body. A stirring rod is provided on the part of the rotating shaft located in the inner cavity. A plurality of vertical rods evenly distributed on itself are provided on the stirring rod. A plurality of inclined rods are provided at the end of the stirring rod far from the stirring rod, and the plurality of inclined rods are evenly distributed on the stirring rod. A cross block is provided on the rotating shaft. A bent rod is provided on the upper surface of the cross block. A diversion rod is provided at the end of the cross block far from the rotating shaft. The cross block is arranged above the stirring rod. The utility model can not only stir the emulsified asphalt at the rotating shaft, but also stir the emulsified asphalt between the rotating shaft and the inner wall of the tank body, avoiding the situation of uneven stirring.

[0004] Based on the above, when stirring stratified emulsified asphalt at the construction site, first, the emulsified asphalt needs to be poured into the stirring barrel. After the stirring process is completed, the emulsified asphalt is discharged from the discharge port. At this time, since the position of the discharge port is relatively low, it is necessary to first receive the emulsified asphalt with a small container and then transfer it to a large container for subsequent use. From the discharge to the final spraying operation, containers need to be frequently replaced and various tools need to be used throughout the process. This series of operations is relatively complex and cumbersome. Summary of the Utility Model

[0005] To solve the above technical problems, the present utility model provides a secondary stirring device for cold recycling of emulsified asphalt, so as to solve the problem that when stirring stratified emulsified asphalt at the construction site, it is first necessary to pour the emulsified asphalt into the stirring barrel. After the stirring process is completed, the emulsified asphalt is discharged from the discharge port. At this time, since the position of the discharge port is relatively low, it is necessary to first receive the emulsified asphalt with a small container and then transfer it to a large container for subsequent use. From discharging to the final spraying operation, containers need to be frequently replaced and various tools need to be used throughout the process, and this series of operations is relatively complex and cumbersome.

[0038] Secondly, when the driving motor drives the first stirring member to rotate, it will also drive the second stirring member to rotate in a direction opposite to that of the first stirring member through the reverse stirring assembly, thereby generating stronger shear force and tensile force, which helps the emulsified asphalt in the stirring barrel to be dispersed and mixed more quickly.
