Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete modifier processing technology, specifically to an asphalt concrete modifier addition control device. Background Technology

[0002] Asphalt modifiers are natural or synthetic organic or inorganic materials added to asphalt or asphalt mixtures. They can be melted or dispersed in the asphalt to improve or enhance its road performance. In the production process of asphalt concrete modifiers, asphalt concrete modifier addition control devices are often required.

[0003] Utility model patent CN214934280U discloses a modifier addition device for asphalt production, including a grinding box and a feeding box. The feeding box is fixedly connected to the lower end of the grinding box, and a first drive motor is fixedly connected to the upper surface of the grinding box. The output end of the first drive motor is fixedly connected to a rotating rod through a coupling, and the rotating rod extends into the grinding box through a bearing. The beneficial effects of this utility model are: when the modifier is placed into the grinding box, the first drive motor is driven to drive the rotating rod and the grinding cylinder to rotate, grinding and breaking up the blocky modifier in the grinding box. The modifier falls into the feeding box through the discharge hole and onto the collection plate. The second drive motor is then driven to drive the threaded rod to rotate, and under the limitation of the support rod, the threaded nut and the support rod move, adjusting the horizontal angle of the collection plate. Under the action of gravity, the feeding speed is adjusted, and the modifier is broken up, increasing the addition efficiency.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that it is usually impossible to automatically mix or disperse the modifier during each use, which makes it inconvenient to change the properties of the modifier. At the same time, it is not convenient to install the device on the surface of the storage device, which may have a certain impact on the overall addition efficiency.

[0005] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

Transmission gears 5-8 are provided on the outside of the horizontal shaft 5-7 and the upper end of the rotating frame 5-5. Several transmission gears 5-8 are provided on the outside of the horizontal shaft 5-7.

[0036] In this embodiment, to achieve the effect of continuous dispersing and agitation of the modifier, a stirring assembly 5 is designed. Two slide rails 5-1 are provided on the top of the storage tank 1, and a movable frame 5-2 is slidably connected between the slide rails 5-1, allowing linear movement on the top of the storage tank 1.
