Abstract

The invention discloses an automatic screening device for aggregate of a cementing dam building material. The automatic screening device comprises a housing, a feeding hopper, a feeding groove and a supporting frame, wherein the feeding hopper is arranged on one side of the upper part of the housing; the feeding groove is formed in the housing; the supporting frame is arranged below the housing; acontrol device is further arranged on the housing; a plurality of screening plates are arranged in the housing; mounting bases are arranged on the portions, on one sides of the upper ends of the screening plates, of the housing; motors are arranged on the mounting bases; the output ends of the motors are in transmission connection with rotating discs; rotating shafts are arranged below the screening plates; the motors can drive the screening plates to move back and forth on the rotating shafts through transmission rods; a discharging opening is formed in the lower end of the housing; and second connecting plates are obliquely arranged on the two sides of the discharging opening. According to the automatic screening device, the aggregate can be automatically screened in a multi-stage manner at a time, the aggregate screening work efficiency is greatly improved, and the production cost is reduced; and damage of vibration to the device can be relieved, and the problems that aggregate screening is incomplete, vibration damage is caused, the service life is shortened, the work efficiency is low, and the production cost is high are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of preparation of materials for cemented dams, and in particular relates to an automatic screening device for aggregates of materials for cemented dams. Background technique [0002] Cemented dam is a new type of dam developed based on the new dam concept of "suitable material for structure, suitable structure for material". It is between earth-rock dams and concrete dams, including cemented sand and gravel dams Sand and gravel dam), cemented artificial sand and gravel dam, cemented rockfill dam, cemented earth dam, etc., use a small amount of cement, admixture, fly ash to cement natural sand, gravel, stone and engineering excavation materials, etc., to form a continuous and complete structure composed of The pedigree of damming materials from bulk aggregates to concrete. [0003] Cemented dams have lower requirements on dam construction materials. The maximum particle size of aggregates is relaxed from 80m...
