The present invention relates to the technical field of construction engineering, more specifically, it is a circular sand screening device for construction engineering, comprising a sand screening machine body, the sand screening machine body is provided with a feed port, and the sand screening machine body is equipped with a There is a sand screening assembly, and the sand screening assembly includes a sand rejection mechanism and a sand screening mechanism. The sand rejection mechanism includes a feed pipe fixedly installed in the sand screen machine body, and one end is hinged on the feed pipe and is adapted to it. The material throwing dish and the driving box, the driving box is fixedly installed on the material guide pipe, and the hydraulic pipe is fixedly installed on the driving box and communicated between the two, the piston is slidably installed in the hydraulic pipe, and the A slide bar is fixedly connected between the piston and the other end of the throwing dish, and a slide plate is slidably installed in the drive box; the present invention adopts a linkage structure, gets rid of the traditional motor drive mode, saves a lot of electric energy, and imitates It replaces the traditional manual sand screening method and improves the sand screening effect.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction engineering circulating sand screening device. Background technique [0002] Construction engineering refers to engineering entities formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines, and equipment. Housing construction refers to roofs, beams, walls, foundations and A project that forms internal space and meets people's needs for production, living, learning, and public activities. [0003] The existing construction sand screening device has a simple structure. After the coarse sand is separated from the fine sand, the coarse sand is wasted and cannot be used any longer. Moreover, although machines are currently used for automatic sand screening, the effect of machine sand screening is not as good as that of traditional manual manual screening. ...
