sand and gravel mixing equipment

Abstract

The invention discloses a sand and gravel mixing equipment, which comprises a base, a mixing chamber is fixed on the top of the base through a support column, and a crushing chamber is arranged on the top of the mixing chamber, and one side of the crushing chamber is respectively installed with a The first crushing motor and the second crushing motor, the output end of the first crushing motor penetrates to the interior of the crushing chamber and is connected to the first crushing roller, and the outer wall of the first crushing roller is uniformly welded with first crushing teeth. In the present invention, the first crushing motor drives the first crushing roller to rotate clockwise, and the second crushing motor drives the second crushing roller to rotate clockwise, so that the installation direction is opposite, and the volume of the first crushing teeth and the second crushing teeth set in mutual meshing Larger stones are broken, and the stirring shaft is driven by the stirring motor to rotate, so that the first stirring blade and the second stirring blade arranged alternately can stir the raw materials in the mixing chamber, and the mixing effect is better and better.

Description

technical field [0001] The invention relates to the field of building construction, in particular to sand and gravel mixing equipment. Background technique [0002] With the rapid development of my country's economy and the acceleration of urbanization, my country's urban infrastructure and real estate development industries have developed rapidly. Now construction needs to mix sand, cement and stones, and the resulting concrete is used for pouring For foundation or masonry walls, the quality of concrete directly affects the quality of the building. The more uniform the sand and stones are mixed, the better the quality of the concrete will be. Traditional mixing methods are mostly manual mixing, and some mixers are also used to mix them. mixed. [0003] When the stone is too large, it will affect the quality of the concrete, and after the existing sand mixer is finished mixing, it is very inconvenient to discharge the material. A large amount of concrete will be attached to t...

AI Technical Summary

Problems solved by technology

[0003] When the stone is too large, it will affect the quality of the concrete, and after the existing sand mixer is finished mixing, it is very inconvenient to discharge the material. A large amount of concrete will be attached to the inner wall of the mixer. If the concrete is not processed in time, the concrete may solidify on the inner wall of the mixer. It not only affects the use of the mixer, but also causes a waste of resources. After the mixing is completed, the concrete needs to be transferred to the mixer truck, and then transported to the designated construction site by the mixer truck. However, the existing mixer does not have the function of automatic feeding. very inconvenient
