Abstract

The invention relates a screening device, in particular to a quantitative gravel multistage screening device for concrete. According to the technical purposes to be achieved, the quantitative gravel multistage screening device for the concrete is provided, multistage gravel screening can be achieved, and screening can be sufficient. In order to achieve the above technical purposes, the quantitative gravel multistage screening device for concrete is provided and comprises a screening box and the like. A feeding mechanism is arranged at the upper portion of the screening box, and screening mechanisms are evenly arranged in the screening box. The quantitative gravel multistage screening device for concrete is arranged, the feeding mechanism is arranged so that gravel can be quantitatively added, in addition, the gravel does not need to be poured into the screening box at a time, and the screening efficiency is high; and the screening mechanisms are arranged so that classified screening ofthe gravel can be achieved, the gravel can be used with different purposes, manual screening is not needed, and the screening time is saved.

Description

technical field [0001] The invention relates to a screening device, in particular to a quantifiable gravel multistage screening device for concrete. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] Grit refers to a mixture of sand and gravel, pebbles and boulders (a type of rock that has been eroded by water or weather) are also known as gravel. Among gravel, gravel, silt and clay, gravel is the largest, with a diameter of more than 2mm, sand is second, with a diameter of less than 2mm, silt is the third, with a diameter of less than one sixteenth of ...
