Sand stone screening device for road construction

Abstract

The invention discloses a sand stone screening device for road construction. The sand stone screening device comprises a bottom plate and is characterized in that the bottom plate is fixedly connectedwith a vertical plate; the vertical plate is provided with a first notch; the vertical plate is fixedly connected with symmetrical fixing blocks; the symmetrical fixing blocks are fixedly connected with a material box; the material box is fixedly connected with an inclined plate; the material box is provided with a second notch corresponding to the inclined plate; the vertical plate is fixedly connected with a first round rod; the vertical plate is fixedly connected with symmetrical upper supporting rods; the symmetrical upper supporting rods are fixedly connected with an upper box body; thevertical plate is fixedly connected with symmetrical lower supporting rods; the symmetrical lower supporting rods are fixedly connected with a lower box body; the vertical plate is fixedly connected with a guide block; and the vertical plate is fixedly connected with a screening mechanism. The invention relates to the field of screening equipment, in particular to the sand stone screening device for road construction. The sand stone screening for road construction is facilitated.

Description

technical field [0001] The invention relates to the field of screening equipment, in particular to a sand and gravel screening device for road construction. Background technique [0002] Highway engineering refers to the investigation, measurement, design, construction, maintenance and management of highway structures. Highway engineering structures include: subgrades, road surfaces, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops and other service facilities used for construction, maintenance and monitoring. [0003] Sand and gravel are used in road construction. Generally, when using sand and gravel, it is necessary to classify and screen the sand and gravel. Ordinary sand and gravel screening mechanism can only simply vibrate the flat sieve up and down or left and right to screen particles, and cannot realize the posture of shaking up and down to simulate the manual shak...

AI Technical Summary

Problems solved by technology

Ordinary sand and gravel screening mechanism can only simply vibrate the flat sieve up and down or left and right to screen particles, and cannot realize the posture of shaking the dustpan by shaking up and down, so that the particles that need to be screened can communicate more fully and improve the screening efficiency
