Mortar stirring device

Abstract

The invention discloses a mortar stirring device, which comprises a motor, a stirring mechanism, and a material barrel. The material barrel is in the shape of a drum. The main rotating shaft installed vertically is fixed on the top or bottom of the barrel, and the main rotating shaft rotates under the drive of the motor through the first transmission mechanism, so that the outer stirring arm rotates accordingly; the inner stirring arm is installed vertically on the outer stirring The slave shaft on one side of the arm is placed on the outer stirring arm. While the outer stirring arm rotates, the second transmission mechanism transmits the rotation of the main shaft of the outer stirring arm to the slave shaft of the inner stirring arm, so that the inner stirring arm follows the outer stirring arm. When the arm rotates, it rotates around the slave shaft; the size of the outer stirring arm and the inner stirring arm ensures that the two do not interfere with each other when rotating. The planetary stirring mechanism provided by the invention can more fully stir the mortar. In addition, the stirring blades are always stirring under the surface of the mortar without bringing 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 as follows: figure 1 As shown, the stirring mechanism has two horizontally placed first rotating shafts 101 and second rotating shafts 102 on the same horizontal plane, and the two rotating shafts are driven to rotate by motors (not shown). 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, an...

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
