Abstract

The invention is applicable to the technical field of concrete, and provides a concrete raw material screening device. The screening device comprises a machine frame used for supporting and mounting,a hopper fixedly installed on the machine frame and used for containing concrete raw materials, a sieve plate slidably arranged on the machine frame below the hopper and used for sieving the concreteraw materials, a feeding roller rotationally arranged in the hopper and used for controlling feeding of the concrete raw materials, and a driving part connected with the feeding roller and the sieve plate through transmission parts and used for driving the feeding roller to rotate for feeding and driving the sieve plate to slide for screening, wherein the transmission parts comprise a first gear,an intermittent gear, a second gear and a rack, the rack is at least fixed to one end of the non-sliding side of the sieve plate, the first gear, the intermittent gear and the second gear are rotationally connected to the machine frame, and the second gear is meshed with the rack. The screening device has the advantages of simple structure, convenient operation, energy conservation, good synchronism, high screening efficiency and convenience in popularization and implementation.

Description

technical field [0001] The invention belongs to the technical field of concrete, in particular to a concrete raw material screening device. Background technique [0002] With the development of society, the construction of roads and buildings requires concrete for construction, which drives the rapid development of concrete production. 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. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. bigger. At the same time, concrete also has the characteristics of high compressive s...
