Building construction gravel crushing device

Abstract

The invention is applicable to the related technical field of crushing, and provides a building construction gravel crushing device. The building construction gravel crushing device comprises a machine body, and a feeding part and a discharging port are arranged on the machine body. The building construction gravel crushing device further comprises a crushing assembly, the crushing assembly comprises a telescopic part, the telescopic part is installed on the machine body, a pressing seat is fixed to the extending end of the telescopic part, a center tip crushing part and a crushing impact part are fixed to the bottom of the pressing seat, multiple rotating tip crushing parts are further rotationally installed on the pressing seat and are annularly distributed, and the rotating directions of every two adjacent rotating tip crushing parts are opposite. According to the building construction gravel crushing device, the combined action of multiple crushing modes is achieved, the crushing effect is guaranteed, and materials on a circular screen plate can be stirred in an all-dimensional reciprocating manner, so that gravel gathering is achieved, gravel screening is accelerated, and the crushing process is accelerated.

Description

technical field [0001] The invention belongs to the technical field related to crushing, and in particular relates to a sandstone crushing device for building construction. Background technique [0002] Sandstone refers to a loose mixture of sand grains and crushed stones. In geology, mineral or rock particles with a particle size of 0.074~2mm are called sand, and those with a particle size larger than 2mm are called gravel or breccia. Most of them are gravel, called sand and gravel, and some people call sandstone sandstone in daily life. [0003] Because of its good hardness and stable chemical properties, sand and gravel are often used as high-quality building materials and concrete raw materials and are widely used in housing, roads, highways, railways, engineering and other fields. After sand and gravel mining, its size is too large and the size However, sand and stones of uniform size are used in construction, so sand and stones need to be crushed. [0004] The existi...
