Abstract

Disclosed are an aggregate premixing apparatus (30) and an asphalt mixture stirring device. The aggregate premixing apparatus comprises a shell (31) and a stirring unit (32) disposed in the shell (31). The shell (31) comprises an inner chamber (310) as well as a feeding port (312) and a discharging port (314) that are in communication with the inner chamber (310). The inner chamber (310) comprises a first inner chamber area and a second inner chamber area. The stirring unit (32) comprises a rotating shaft (320) crosswise and rotatably arranged in the shell (31), a first blade unit (321) arranged on a first shaft section of the rotating shaft, and a second blade unit (322) arranged on a second shaft section of the rotating shaft. The first blade unit (321) and the second blade unit (322) can rotate following the rotating shaft and are respectively corresponding to the first inner chamber area and the second inner chamber area of the shell (31). During a working process, when the first blade unit (321) and the second blade unit (322) rotate following the rotating shaft, the first blade unit (321) drives a part of aggregate in the first inner chamber area to the second inner chamber area, and the second blade unit (322) stirs the aggregate in the second inner chamber area.

Description

technical field [0001] The invention relates to a mixing device, in particular to an aggregate mixing device. Background technique [0002] Various aggregates (also known as aggregates) required by asphalt mixing equipment are often mixed in proportion to a variety of sand and gravel materials with different particle sizes. Therefore, each material must be strictly measured, but due to sand There is a stacking angle for the stone materials. In the actual measurement, each material is relatively independently stacked in the measurement bin, and the self-flowing method is also adopted when unloading. In this way, various materials will be relatively concentrated when put into the mixer. In related technologies, in order to improve the uniformity of the mixture, the mixer has to set a dry mixing time (that is, the mixing before adding asphalt). extended accordingly. The dry mixing time not only affects the mixing cycle and equipment production efficiency, but also the wear o...
