Opposite mixing mechanism for compulsory type asphalt mixing machine

Abstract

The invention discloses an opposite mixing mechanism for a compulsory type asphalt mixing machine, comprising a mixing shaft and a plurality of groups of opposite mixing units sequentially arranged onthe mixing shaft. The mixing shaft and the opposite mixing units arranged on the mixing shaft form the opposite mixing mechanism which can continuously push and mix materials. Each opposite mixing unit comprises two linear mixing arms and two mixing blades, wherein the linear mixing arms are symmetrically arranged at both sides of the mixing shaft with the same structure and size; the mixing blades are respectively arranged at the tail ends of the two mixing arms with the same structure and size; and the directions for the two mixing blades to push the materials to move in the axial directionare the same. The invention has reasonable design, high mixing efficiency and good mixing quality, and can effectively solve the practical problems of limited number of mixing blades in work, low mixing efficiency, poor mixing quality, and the like of the prior compulsory type mixing machines.

Description

technical field [0001] The invention belongs to the technical field of intermittent forced mixing equipment, and in particular relates to an opposed stirring mechanism for an asphalt forced mixer capable of improving the mixing quality of asphalt mixture. Background technique [0002] Intermittent forced mixing equipment is a kind of asphalt mixture mixing equipment widely used in my country, among which twin-shaft mixer is the main mixing machine commonly used in this type of equipment. Correspondingly, as the main structure and working parameters of this type of mixer, the arrangement of the mixing arm has a direct impact on the mixing quality and efficiency of the mixture. Among the existing domestic mixers of this type, the manufacturers all adopt the arrangement of the mixing arms with the surrounding flow arrangement of the mixing arms. When the four fingers rotate along the stirring shaft, the pointing of the thumb is the flow direction of the material; and the stirr...
