AI Technical Summary

Technical Problem

Existing heavy sand sampling and washing devices suffer from center of gravity shift, dynamic imbalance, speed fluctuation, uneven water penetration, and low washing efficiency when materials accumulate.

Method used

The system employs a material distribution component and a vibration component. The material distribution component separates the material through ribs and screens, while the vibration component intermittently lifts the material through a rotating roller and a top block, combined with an auxiliary reset component, to achieve uniform material falling and vibration, thus preventing accumulation.

Benefits of technology

The material is spread evenly, the spray water penetration efficiency is improved, the separation effect of light sand and heavy sand is significant, the washing efficiency is improved, the equipment resistance is reduced, and the service life is extended.

Abstract

This utility model relates to the field of sand washing technology and discloses a heavy sand sampling and washing device for geological and mineral exploration. It includes a support frame, a swing frame, and a washing pan. A pair of smooth rods are fixedly installed on the upper side of the swing frame via support rods. The smooth rods are located above the washing pan, and each smooth rod is slidably mounted with a linear bearing. A common holding hopper is fixedly installed between the linear bearings, with the bottom of the holding hopper extending into the washing pan. A guide component is provided at the bottom of the holding hopper. Limiting rings are fixedly installed on each smooth rod, located below the linear bearings. A vibration component is provided between the holding hopper and the washing pan. During operation, this utility model enables the material to be evenly spread in the washing pan, avoiding local accumulation, improving the penetration efficiency of the spray water, ensuring effective scouring of light sand and stable lifting of heavy sand, significantly improving washing efficiency, reducing equipment operating resistance, and extending service life.
