Commercial concrete production system and production method thereof

Abstract

The invention provides a commercial concrete production system and a production method thereof. The commercial concrete production system comprises a machine body, and is characterized by further comprising a feeding unit arranged at the upper end of the machine body and used for controlling orderly feeding of materials, a mixing unit arranged on the machine body in the X direction, and a cement dispersing assembly arranged in the mixing unit. Sand freely falls to the bottom end of a mixing barrel along guide-out holes in the lower end of a screening area, at the same time, when cement is conveyed into a grid barrel from the left side of a cement transfer barrel through a spiral rod, the cement is dispersed out of the grid barrel along spraying holes firstly, then injected into the dispersing mechanism through an air pump mechanism to be distributed, and further blown away along air sprayed out of air spraying holes, and the cement blown away is mixed with the sand falling down along the guide-out holes in the lower portion of the screening area, so that the effects that the cement and the sand are mixed in a layered mode, the stirring time is shortened, mixing is more uniform, and the processing efficiency is high are achieved.

Description

technical field [0001] The invention relates to the technical field of concrete production, in particular to a commercial concrete production system and a production method thereof. Background technique [0002] Concrete is one of the most important civil engineering materials and is widely used in the construction industry. Among them, the production materials of concrete are mainly cement, sand and gravel. In the preparation of concrete, it is usually necessary to mix cement, sand and gravel , and then do further processing, therefore, mixing concrete raw materials is an important step in concrete processing. [0003] Chinese patent CN109366742B discloses a concrete production system and its production method, including a sand feeding device, a cement feeding device, a gravel feeding device, a sand and mud mixing device, a gravel screening screw guide trough, a sand and mud gravel mixing device and Concrete mixer, the sand feeding device can supply the raw material sand r...

AI Technical Summary

Problems solved by technology

[0004] However, in this technical solution, the cement and sand are directly poured into the mixing tank for mixing. Since the cement is in the form of powder and the sand is in the form of granules, when the sand has fallen into the mixing tank, the cement still slowly enters in the air. to the mixing tank, resulting in uneven mixing and long mixing time in the later stage, which affects the processing efficiency of cement. In addition, when the cement and sand are mixed and put into the second mixing tank, the gravel is poured directly into the mixing tank. Between the two, because the gravel particles are large, it will vibrate violently when poured directly between the cement and sand, and the shock absorption effect is poor, which will affect the service life of the equipment
