Abstract
The invention discloses a concrete raw material screening device, comprising a screening box, the top of the screening box is movably connected with a box cover, and a first screening net is arranged inside the screening box, and the two sides of the first screening net are connected with the The two sides of the inner wall of the screening box are fixedly connected, and the inside of the screening box is provided with a second screening net at the bottom of the first screening net, and the two sides of the second screening net are fixedly connected with the two sides of the inner wall of the screening box, and the screening The left side of the bottom of the box is fixedly connected with a lifting rod, and the bottom of the screening box is provided with a working box. The present invention is provided with connecting plates, sleeves, transmission rods, rockers, slots, rods, gear one, rotating column, gear two, turntables, L-shaped connecting rods, movable plates, movable slots, movable blocks and moving rods. With the cooperation, the screening box can be moved in real time, which achieves high screening efficiency, can completely screen the impurities in the concrete, saves a lot of time for workers, and is convenient to use.
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. Contents of the invention [0003] The ...
