Cemented sand and gravel mixing device

Abstract

The invention provides a cemented sand and gravel mixing device. The cemented sand and gravel mixing device comprises a conveying belt and a control chamber, wherein a plurality of aggregate hoppers are symmetrically arranged on the two sides of the conveying belt; discharging pipes extend out of the outer surfaces of the sides, close to the conveying belt, of the aggregate hoppers; the end partsof the plurality of discharging pipes extend towards the direction close to each other; blocking mechanisms are movably inserted into the outer surfaces of the discharging pipes; a feeding channel isfixedly arranged below the front of the conveying belt; an ash box is arranged on one side of the feeding channel; the outer surface of the ash box extends out of a feeding cylinder which strides overthe feeding channel; and a screw pushing mechanism is rotationally arranged on the inner side of the feeding cylinder. According to the cemented sand and gravel mixing device, aggregate cannot be excessively accumulated on the conveying belt, and the aggregate of different types can be fully mixed when the aggregate is added; and overflow of cement and fly ash is effectively prevented, due to thefact that the positions of discharged materials are increased, uniform adding is facilitated, excessive accumulation during adding is prevented, and subsequent full mixing is facilitated.

Description

technical field [0001] The invention relates to cemented sand and gravel mixing equipment, which belongs to the technical field of mixing. Background technique [0002] Concrete sand and gravel is a dam building material with certain strength and shear resistance formed by mixing, paving and vibrating rolling by using cement, fly ash and other admixtures and sand and gravel materials. It can be used for hydraulic permanent small and medium-sized Dams, temporary dam bodies or cofferdams are mainly processed by mixing equipment in the prior art. [0003] In the prior art, it is often necessary to add a variety of aggregates according to the needs for the addition of aggregates. However, when aggregates are sprinkled from different aggregate hoppers, different aggregates are scattered in piles on the surface of the conveyor belt. It is not conducive to the uniform mixing of aggregates. Secondly, it is prone to splashing when pouring fly ash and cement. At the same time, the po...

Problems solved by technology

[0003] In the prior art, it is often necessary to add a variety of aggregates according to the needs for the addition of aggregates. However, when aggregates are sprinkled from different aggregate hoppers, different aggregates are distributed in piles on the surface of the conveyor belt. It is not conducive to the uniform mixing of aggregates. Secondly, it is prone to splashing when pouring fly ash and cement. At the same time, the position is relatively concentrated when pouring, which is not conducive to full mixing. The remote control effect of the entire mixing equipment is poor. , there are straws, hay and other sundries in the aggregate during mixing, which will affect the quality of the finished product in the later stage
