Crushing and stirring device for building cement

Abstract

The invention discloses a crushing and stirring device for building cement, which comprises a frame and a base. The frame includes a stirring box and a crushing box. The right end of the rotating shaft is equipped with a driving wheel, the middle position of the frame is horizontally provided with a first transmission shaft, the left end of the first transmission shaft is equipped with a primary driven wheel and a secondary driven wheel, and the driving wheel and the primary driven wheel They are connected by the first belt, the second transmission shaft and the third transmission shaft are horizontally arranged in the crushing box, the second transmission shaft and the third transmission shaft are horizontally parallel, and the left end of the second transmission shaft is installed with The third-stage driven wheel, the second-stage driven wheel and the third-stage driven wheel are connected through the second belt; the beneficial effect of the present invention is: the transmission structure of the belt and the gear is utilized, the working motor is reduced, and the operation safety is improved , fully milled and crushed to improve the quality of the material.

Description

technical field [0001] The invention relates to a construction machine, in particular to a crushing and stirring device for construction cement. Background technique [0002] Cement: powdery hydraulic inorganic gelling material. After adding water and stirring, it becomes a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together. In the early years the mixture of lime and volcanic ash is very similar to lime pozzolanic cement, use it to glue concrete which made of crushed stone. After hardening, the cement not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, as an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. [0003] The existing concrete mixing device generally puts all the cement and sand into the mixing box directly when processing concrete. Although the mixing ca...

Problems solved by technology

[0003] The existing concrete mixing device generally puts all the cement and sand into the mixing box directly when processing concrete. Although the mixing can be completed, part of the cement and sand are bonded together at the beginning. If they are not crushed and separated, It is difficult to mix evenly, and part of the concrete will adhere to the inner wall of the mixing tank during the mixing process, resulting in waste of resources
