Gravel sorting device for construction

Abstract

The invention is applicable to the technical field of construction equipment, and provides a gravel sorting device for construction. The sorting device comprises a coarse screen, a rotating roller, aseparating screen box and a fine screen, the coarse screen is mounted at a top opening of the separating screen box and is of an arc-shaped structure; the rotating roller is mounted at the upper part,corresponding to the coarse screen, of the separating screen box; mounting positions for hinging and mounting a hopper are arranged on the rotating roller at equal intervals; the hopper comprises atleast one mixing hopper and at least one shoveling hopper; and a plurality of open slots are formed in a hopper body of the mixing hopper and are used for spreading gravel in the coarse screen, and awaist-shaped hole is formed in the hopper; and the gravel sorting device has the beneficial effects that due to the arrangement of the rotating roller, the mixing hopper and the shoveling hopper on the rotating roller, gravel can be effectively spread to improve the screening effect, meanwhile, screened gravel can be automatically output outwards, manual interference is basically not needed in thewhole process, and automatic screening, feeding, discharging, unloading and the like of the gravel can be achieved.

Description

technical field [0001] The invention relates to construction equipment, in particular to a construction sand and gravel sorting device. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment. According to different construction requirements, the requirements for sand and gravel in the construction process are also different. Some require coarse sand and gravel, and some require fine sand and gravel. Therefore, the sand and gravel need to be sorted before use. [0003] Most of the existing sand and gravel grading and screening are realized by multiple screening, but the sand and gravel accumulated on the screen cannot be unloaded effectively or conveniently, resulting in the need to manually clean the screen after the device has been running for a period of time.
