A concrete production equipment system

Abstract

The invention relates to a concrete production equipment system, and belongs to the field of concrete production equipment. By means of the system, the problem that by means of an existing sand screening machine, multiple specifications of sand cannot be screened is solved. The system comprises a feeding device and a measuring hopper, the feeding device comprises a support and a feeding hopper, asand screening machine is arranged between the feeding hopper and the measuring hopper, the sand screening machine comprises a rack, a rotating shaft, installation rings fixedly arranged on the rotating shaft, fixing rods arranged on the installation rings and a motor fixedly arranged on the rack, arc kidney-shaped holes are formed in the two installation rings, a mobile rod is arranged between every two adjacent fixing rods, the mobile rods are fixedly connected with a fixing ring, and limiting assemblies are arranged on the rack and the fixing ring. When thinner sand needs to be screened outto produce another sanctification of concrete, the fixing ring is rotated to make each mobile rod slide along the corresponding arc kidney-shaped hole and be located at the middle position of the corresponding two adjacent fixing rods, the mobile rods are fixed through the limiting assemblies, the gap between the fixing rods is reduced, and thus the purpose of screening out the thinner sand is achieved.

Description

technical field [0001] The invention relates to the field of concrete production equipment, in particular to a concrete production equipment system. Background technique [0002] In the concrete mixing process, according to the production needs, the particle size of the sand and gravel raw materials used is also different. Generally, according to the particle size of sand and gravel, sand and gravel raw materials can be divided into fine sand, medium sand, coarse sand and waste materials. The above-mentioned classification standards for fine sand, medium sand, coarse sand and waste materials can be set according to actual needs. The sand material with a particle size greater than 5mm is considered waste, the sand material with a particle size less than 0.6mm is considered fine sand, the sand material with a particle size between 0.6-1.2mm is considered medium sand, and the sand material with a particle size between 1.2mm The sand between -5mm is considered as coarse sand, h...

AI Technical Summary

Problems solved by technology

However, the existing sand screening machines can usually only screen sand materials of one specification. When it is necessary to produce sand materials of different grades, it is necessary to remove the original sand screening machine and install another sand screening machine of other specifications, which is time-consuming. laborious, reducing work efficiency
