Problems solved by technology

However, the problem is that the sand and concrete in the concrete are all powder materials, which are easily dispersed into the air when the materials are cut, resulting in air pollution.
In addition, in order to prevent rainwater and other influences, the grading machine usually needs to be installed indoors, resulting in a large footprint

Abstract

The invention discloses an environment-friendly and efficient grading machine. The environment-friendly and efficient grading machine comprises a lower conveying belt and an upper conveying belt. The lower conveying belt comprises a C-shaped conveying part and an O-shaped conveying part; the upper conveyor belt covers the upper part of the C-shaped conveying part; a plurality of feeding ports are inserted between the lower conveying belt and the upper conveying belt and communicate with a plurality of quantitative discharging structures correspondingly. The environment-friendly and efficient grading machine has the advantages that the structure is simple; the use is convenient; and materials can be effectively prevented from overflowing or being washed away by water in the grading process, so that the device does not need to be mounted in a plant, the space of the plant is saved, and the environment-friendly requirement is met.

Description

technical field [0001] The invention belongs to the field of concrete, in particular to an environmentally friendly and efficient grading machine. Background technique [0002] When concrete is mixed, various materials such as sand and gravel are usually required. In addition, the sand and gravel used also need to be graded according to the particle size range. For example, sand is divided into coarse sand, medium sand and fine sand. Match in proportion. However, in the existing grading machines, several different feed bins are usually arranged above a conveyor belt, and different materials are released for grading according to needs. However, the existing problem is that the sand and concrete in the concrete are all powder materials, which are easily dispersed into the air during blanking, causing air pollution. In addition, in order to prevent rainwater and other influences, the grading machine usually needs to be installed indoors, resulting in a large footprint. There...
