Abstract

The invention discloses a method for producing fine sand concrete gel containing waste stone dust through a concrete mixing device. The concrete mixing device comprises a mixing tank and supporting legs fixed to the bottom of the mixing tank. One side of the mixing tank communicates with a feed hopper. The bottom of the mixing tank communicates with one end of a discharge pipe. The concrete mixingdevice is simple in structure. A motor drives a hollow shaft to rotate. The hollow shaft and a fixed shaft rotate relatively to drive mixing shafts to rotate to conduct mixing on a raw material for the first time. A first bevel gear is engaged with a fourth bevel gear to drive the mixing shaft to rotate and then drive rotary shafts and spiral blades to conduct mixing on the raw material for the second time. When the rotary shafts revolve around the hollow shaft, under the action of springs, racks abut against corresponding arc-shaped blocks intermittently and are driven to do reciprocation motion. The racks are engaged with spur gears to drive the rotary shafts and the spiral blades to do reciprocating rotation to conduct mixing on the raw material for the third time. The raw material ismixed more evenly through three combined mixing, and the strength of concrete is guaranteed. Meanwhile, the hollow shaft drives the spiral blades to rotate through a connecting shaft, and the concretecan be discharged smoothly to prevent blockage.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a gelling production method of fine sand concrete containing waste rock powder. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering; the existing concrete mixing device is not uniform enough to mix, resulting in insufficient concrete strength. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a concrete mixing device to produce a cementati...
