A construction sand and stone sorting device

Abstract

The invention discloses a building sandstone sorting device. The sorting device is characterized in that a driving shaft is rotationally connected to the lower end of a driving motor, a sandstone boxis arranged on the upper part of a device body, and a driving shaft bearing is rotationally connected with the sandstone box; and a plurality of stirring rods are fixedly connected to the middle of the driving shaft, the two sides of the bottom of the sandstone box are provided with material guide pipes respectively, two semi-circle bevel gears are arranged at the lower part of the sandstone box,and the semi-circle bevel gears are fixedly connected with the driving shaft, two bevel gears are arranged on the two sides of the semi-circle bevel gears correspondingly, the bevel gears are fixedlyconnected with the end parts of rotary shafts, and the rotary shafts are connected with the lower parts of hanger rods in a sleeved mode. According to the sorting device, the driving shaft drives thesemi-circle bevel gears to rotate to drive the bevel gears and the threaded rods on the left side and the right side to do reciprocating forward and reverse rotation, the threaded rods drive movable baffles to move left and right, so that the material guide pipes communicate with the device body in a reciprocating mode, and intermittent material falling is realized, meanwhile, the rotating drivingshaft drives the stirring rods to rotate so as to stir the sandstone in the sandstone box, and the sandstone is prevented from being agglomerated in the sandstone box and not falling, and a cam drives a screening plate to move left and right in a reciprocating mode to screen the sandstone falling from the material guide pipes.

Description

technical field [0001] The invention relates to a construction machine, in particular to a construction sand and stone sorting device. Background technique [0002] Construction sand is the most common building material. With the rapid development of my country's construction industry, the requirements for high automation of construction machinery are getting higher and higher. By improving the automation of construction machinery, the progress of the project is accelerated. Construction sandstone is mainly composed of quartz particles, with a small amount of debris and muddy river, lake, marine debris deposits and hard and unweathered rock artificial mechanical crushing. It is used as concrete aggregate. Concrete is based on cement , water, sand and coarse aggregate pebbles are mixed and hardened artificial stone, etc., which are widely used in construction projects. Since construction sand and stone usually contain a large amount of impurities such as stones, most of them ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing sand and gravel removal and sorting still rely on manual work, which has a low degree of automation, low work efficiency and requires a large amount of labor, which is not conducive to speeding up the construction progress of the project and hinders the rapid development of my country's construction industry.
