Concrete raw material screening device

Abstract

The invention discloses a concrete raw material screening device. The concrete raw material screening device comprises a screening box. A box cover is movably connected to the top of the screening box. A first screen is arranged inside the screening box, and the two sides of the first screen are fixedly connected with the two sides of the inner wall of the screening box. A second screen is arranged in the screening box and located below the first screen, and the two sides of the second screen are fixedly connected with the two sides of the inner wall of the screen box. A lifting rod is fixedlyconnected to the left side of the bottom of the screening box. A work box is arranged at the bottom of the screening box. According to the concrete raw material screening device, a connecting plate,a sleeve, a transmission rod, a rocker, a clamping groove, a clamping rod, a first gear, a rotary column, a second gear, a rotary disc, an L-shaped connecting rod, a moving plate, a moving groove, a moving block and a moving rod are arranged and matched with one another so that the screening box can be moved, the screening efficiency is high, impurities in concrete can be completely removed, timeis greatly saved, and using is convenient.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a concrete raw material screening device. Background technique [0002] Concrete refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to cement as cementitious material, sand and stone as aggregates; water (may contain admixtures) and admixtures) in a certain proportion, and the cement concrete obtained by mixing is also called ordinary concrete. It is widely used in civil engineering. Before the concrete is used, a screening device is required to screen the impurities in the concrete raw material. However, The screening efficiency of the current concrete raw material screening device is low, and the impurities in the concrete cannot be completely screened, which wastes a lot of time for workers and is inconvenient to use.
