Mortar stirring device

Abstract

The mortar stirring apparatus includes one motor, one stirring mechanism, and one cylindrical material barrel. The stirring mechanism is one planetary one including one outer stirring arm and inner stirring arm, the outer stirring arm is fixed to the top or the bottom of the material barrel through the vertically installed main rotation shaft rotating under the drive of the motor through the first driving mechanism, and the inner stirring arm is mounted on the outer stirring arm through one driven rotation shaft. While the outer stirring arm rotates, one second driving mechanism transfers the rotation of the main rotation shaft to the driven rotation shaft, so the inner stirring arm rotates around the driven rotation shaft while revolving with the outer stirring arm. The planetary stirring mechanism has well stirring to the mortar. In addition, the stirring blades always stir under mortar surface without carrying in air.

Description

technical field [0001] The invention relates to a mixing machine, in particular to a mortar mixing device applied in the construction field. Background technique [0002] In the field of construction, various mixing machines are widely used. For example, in the process of building high-speed railway (road) roads, a special asphalt cement mortar (also known as CA mortar or BZM mortar) must be mixed. Mortar is generally processed by a twin-shaft mixer. The structural principle of the twin-shaft mixer is shown in Figure 1. Its mixing mechanism has two first rotating shafts 101 and second rotating shafts 102 placed horizontally and on the same horizontal plane. shown) to drive the rotation. The ends of the two rotating shafts are respectively equipped with a first stirring arm 103 and a second stirring arm 104 perpendicular thereto, and the above stirring arms rotate around their corresponding rotating shafts respectively, and the ends of the rotating arms are respectively fix...

AI Technical Summary

Problems solved by technology

The disadvantage of this twin-shaft mixer is that when the mixing arm and the mixing blade hit the mortar, there is generally a process of stretching out the mortar and exposing it to the air. This process will inevitably bring a large amount of air into the mortar. The air will form many air bubbles in the mixed mortar

But this kind of mortar mixer has only one rotating shaft. When the mixer is working, the rotating shaft can only rotate around the rotating shaft at the center, and the flow direction of the mortar rotation is single. Compared with the twin-shaft mixer, there is insufficient mixing of various components of the mortar. lack of
