Sand and stone mixing equipment

Abstract

The invention discloses sandstone mixing equipment comprising a base, the top of the base is fixed with a mixing bin through a supporting column, the top of the mixing bin is provided with a crushingbin, one side of the crushing bin is respectively provided with a first crushing motor and a second crushing motor by mounting plates, the output end of the first crushing motor penetrates the insideof the crushing bin and is connected to and a first crushing roller, and a first crushing tooth is evenly welded on the outer wall of the first crushing roller. The first driving motor drives the first crushing roller to rotate clockwise, and the second crushing motor drives a second crushing roller to rotate anticlockwise, so that the mounting direction is reversed, the first crushing tooth and asecond crushing tooth which are mutually engaged crush larger stones, and a stirring shaft is driven to rotate by a stirring motor, so that a first stirring blade and a second stirring blade which are arranged alternately are used to stir the raw materials in the mixing bin, and the mixing effect is 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...

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
