Problems solved by technology

[0006] The sand and gravel materials collected from the water body are often attached with a large amount of water, which will increase the load of the equipment during screening and increase the difficulty of screening. The existing screening equipment still has the shortcomings of insufficient screening and poor screening effect. Therefore, we propose A gravel screening machine for traffic construction and its application method

Abstract

The invention discloses a sandstone screening machine for transportation construction. The sandstone screening machine comprises a rack, wherein a feeding barrel is arranged on the left side of the rack; a lifting assembly is arranged on the left side of an inner cavity of the rack; a guiding assembly communicates with the clearance between the lower end of the feeding barrel and the left side wall of the lifting assembly; a stirring assembly is arranged on the right side of the inner cavity; a square tube communicates with the clearance between the upper ends of the stirring assembly and thelifting assembly; a screening assembly is connected with the right side wall of the inner cavity of the rack; a discharging assembly is arranged below the screening assembly; and a first transmissionassembly is connected with the upper part of the rack. The sandstone screening machine is reasonable in structural design; through the sandstone screening machine, a sandstone material can be screenedtwice, and then sandstone particles which meet specifications can be obtained; the arrangement of power equipment can be eliminated, and then the energy consumption cost can be reduced; and the sandstone material can be subjected to pre-dehydrating treatment, the load of subsequent equipment can be reduced, and then the sandstone screening difficulty can be reduced.

Description

technical field [0001] The invention relates to the technical field of sand and gravel dehydration, breaking up and screening equipment, in particular to a sand and gravel screening machine for traffic construction and a use method thereof. Background technique [0002] Construction engineering refers to the general designation of various buildings and engineering facilities that provide the material and technical basis for human life and production. Construction engineering is an organized, purposeful and large-scale economic activity of human beings. Construction projects can be divided into three categories according to their natural attributes: architectural engineering, civil engineering, and electromechanical engineering. Construction engineering is an organized, purposeful, and large-scale economic activity of human beings. It is an engineering project that forms comprehensive production capacity or exerts engineering benefits in the process of reproduction of fixed ...
