Sand-gravel separation device for bridge construction

Abstract

The invention provides a sand-gravel separation device for bridge construction, belongs to the technical field of bridge construction, and is used for solving the problems that an existing sand-gravel screening device is poor in gravel separation effect and low in efficiency and cannot crush sand blocks. The device comprises a box body, a sand inlet hopper is arranged at the upper end of the box body, a plurality of noise reduction assemblies are arranged on the box body, a guide plate II and a guide plate III are fixed to one side of the inner wall of the box body, a guide plate I and a screen are fixed to the other side of the inner wall of the box body, a sand outlet and a stone outlet are formed in the two sides of the box body correspondingly, a plurality of crushing assemblies are arranged inside the box body, and a vibration assembly is arranged at the lower end of the box body. According to the device, through cooperation of the vibration assembly and the screen, sand-gravel can be separated through vibration, the separation effect is good, and the efficiency is high; the crushing assembly can crush the sand blocks, the sand blocks are prevented from blocking the screen, meanwhile, sand waste is avoided, and the sand screening efficiency is improved; and the noise reduction assemblies can absorb noise and prevent noise pollution.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to a sand-stone separation device, in particular to a sand-stone separation device for bridge construction. Background technique [0002] With the rapid development of the ready-mixed concrete industry, the massive consumption of limestone in concrete production and cement industry, the mining resources of natural sand are becoming increasingly exhausted, and the quality is declining. Therefore, sand and stone separation equipment for bridge construction is required for mixing, processing and separation, and the required The separation of sand and gravel can enhance the material stability of bridge construction and facilitate the mixing of sand and gravel in bridge construction. However, the traditional sand and gravel separation device has low removal efficiency of gravel, and the gravel is easy to block the screen hole, which affects the sand screening efficiency. There ...
