Description

Mortar mixer

technical field

The invention relates to the technical field of equipment for preparing mortar and mud mixture, in particular to a mortar mixer.

Background technique

Mortar is a bonding substance used in building bricks. It is made by mixing a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) with water. It is also called mortar and mortar. Commonly used mortars are cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar. The production method of the mortar is to mix various components by a mixer after weighing them in proportion. In construction engineering, the common functions of mortar are: one is to build foundations and walls, and it is used as an adhesive for block masonry materials, such as cement mortar for rubble and red bricks; the other is for indoor and outdoor Plastering.

Existing common mortar mixer is made up of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device etc. The mortar mixer mainly relies on the blade pulp to drive the material to turn, so that the material is in a state of instantaneous weightlessness, which makes the material form an all-round continuous cycle in the machine tank to achieve the effect of rapid mixing and uniformity.

However, the current mortar mixer still has certain defects: due to the high viscosity of the mortar, which is easy to solidify and agglomerate, it is easy to produce agglomerated materials or block the discharge port during the discharge process, which affects the quality of the pulp.

It is not only easy to operate, but also realizes intermittent slurry discharge, which is convenient for workers to carry out other construction operations, such as plastering, while picking up materials.

2. Through the connecting hole, the mortar in the rotating bucket is evenly introduced into the grinding chamber, and then the mortar entering the grinding chamber is ground by the rotation of the grinding disc, so that the condensed block in the mortar is ground into smaller particles. Guarantee the quality of the pulp, and effectively prevent the blockage of the discharge port, and the pulping process is stable.

Preferred option 1, as the preferred option of the basic solution, the control door includes a sealing plug, an extension spring and a moving block that can be squeezed by the toggle block, one end of the extension spring is connected to the fixed barrel, the other end of the extension spring is connected to the sealing plug, and the moving block One end is connected with the sealing plug, and the other end of the moving block passes through the discharge port and is located in the grinding chamber.

When the toggle block rotates to squeeze the moving block, the moving block moves down, the sealing plug is opened, and the mortar is discharged from the discharge port; when the toggle block does not squeeze the moving block, the moving block resets under the action of the tension spring and restart Cover the discharge port; achieve intermittent pulp discharge through a simple structure.

The second preferred solution, as a preferred solution of the first preferred solution, the number of toggle blocks is not less than 2. Helps to improve pulping efficiency.

The third preferred solution, as a preferred solution of the basic solution, the stirring paddle includes a stirring rod and a stirring blade connected to the stirring rod, and the output shaft of the motor is connected to the stirring rod. The mixing range can be expanded and the mixing effect can be improved by setting the stirring blades.
