Device for efficiently mixing concrete, sand and gravels

Abstract

A high-efficiency mixing device for concrete, sand and gravel materials, comprising a bottom plate, on which a rotating shaft is rotatably installed, a mixing barrel is fixedly installed on the rotating shaft, and an annular rack is fixed and sleeved on the outer wall of the mixing barrel; a worm is fixedly installed on the drive shaft, and the top plate The lower side rotating type is equipped with incomplete gears and worm gears, the worm gears are connected with the worm, and the driving pulley is fixedly installed coaxially on the worm gear; the drive plate is fixedly installed on the lower side of the sliding shaft; the vertical rotating type on the bottom plate is equipped with a driven shaft , a cam is fixedly installed on the upper end of the driven shaft, and the cam is in contact with the transmission plate; the structure of the invention is ingenious, the stirring shaft can move up and down while driving the stirring blades to stir, so that the concrete gravel can be turned up and down, and the knocking block is on the sliding shaft The left and right reciprocating motion is driven by the driving force, and the wall of the mixing tank is continuously knocked, which improves the mixing effect and avoids the waste of concrete sand and gravel adhering to the inner wall of the mixing tank.

Description

technical field [0001] The invention relates to the technical field of construction machinery and equipment, in particular to a high-efficiency mixing device for concrete, sand and gravel. Background technique [0002] Concrete, also known as concrete, is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementing material, aggregate and water prepared in a certain proportion, stirred and vibrated, and cured under certain conditions. Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its usage is increasing; at the same time, concrete also has high compressive strength, good durability, and a wide range of strength levels, making it widely used, not only It is used in various civil engineering, that is, shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material.

AI Technical Summary

Problems solved by technology

[0003] Concrete sand and gravel are the most common building materials in the construction process. Before use, concrete sand and gravel need to be mixed and stirred to achieve sufficient mixing between concrete and sand and gravel to ensure that the concrete sand and gravel can achieve a good building effect; The mixing and mixing effect of the existing concrete sand and gravel mixing device is not ideal, and the concrete and the sand and gravel cannot be fully and uniformly mixed. waste of
