Efficient sand screening equipment with dustproof function for road and bridge construction

Abstract

The invention discloses an efficient sand screening equipment with a dustproof function for road and bridge construction. The screening equipment comprises a box body, and two screening frames are installed on the inner face of the box body; the two screening frames are installed on the inner face of the box body through guide assemblies, and screen nets are fixedly installed on the inner faces of the two screening frames; and two fixing plates are fixedly connected to the side face of the box body, and a servo motor is fixedly installed on the side face of one fixing plate. According to the screening equipment, the screening frames do not need to be shaken manually for screening, not only is the labor intensity of workers relieved, but also the sand treatment efficiency is improved; dust generated in the screening process can be absorbed, and prevented from scattering at the position and being inhaled by the workers around the device; the effect of drying wet sand can be achieved, and the phenomenon that the sand is caked due to moisture is avoided; and therefore the sand can smoothly pass through meshes of the screen nets.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a high-efficiency sand screening device for road and bridge construction with a dust-proof function. Background technique [0002] Municipal construction is an important part of municipal activities, the implementation stage of planning and design, and the construction of various public facilities and undertakings sponsored by the city government according to the overall deployment of municipal planning, such as roads, drainage, bridges, etc. [0003] At present, in the process of municipal construction, the use of ready-mixed mortar is relatively frequent. Sand with a suitable moisture content can meet the normal use of ready-mixed mortar. At the same time, when sand is screened, sand with a high water content is easy to form lumps. It is often not possible to screen well during screening, and it is easy to block the screen mesh, resulting in a decrease in screeni...

Problems solved by technology

[0003] At present, in the process of municipal construction, the use of ready-mixed mortar is relatively frequent, and sand with a suitable moisture content can meet the normal use of ready-mixed mortar. When screening, sand with a high water content is easy to form lumps, and it is often not well screened during screening, and it is easy to block the screen holes, resulting in a decline in screening quality. At the same time, at the construction site, the screening of sand Place it on an inclined support, then sprinkle the sand on the screen manually, and use the sand to roll on the screen surface under the action of gravity to achieve the purpose of screening. This screening method is time-consuming and laborious, and the effect is not very good. When encountering sand with a high water content The effect is even less obvious. Secondly, a large amount of dust will be generated during the sand screening process. The traditional sand screening device cannot effectively treat the dust, making the dust easily inhaled by the surrounding staff and posing a threat to the health of the staff. , it is necessary to design a high-efficiency sand screening equipment with dust-proof function for road and bridge construction to solve the above problems
