AI Technical Summary
Technical Problem
In the screening process of traditional vibrating screens and drum screens, dry sand is prone to local accumulation and screen holes are easily blocked, resulting in incomplete screening and low efficiency.
Method used
The reciprocating rotation of the first and second screening discs, combined with air pressure vibration and scraper cleaning structure, expands the movement range of dry sand, prevents accumulation and clears blockages, and achieves two-stage screening.
Benefits of technology
It improves the comprehensiveness and speed of dry sand screening, ensures unobstructed screen holes, and can accurately separate dry sand of different particle sizes to meet various application needs.

Abstract
The utility model discloses a dry sand screening machine, which relates to the technical field of screening machine equipment and comprises an outer barrel, a plurality of groups of first connecting blocks are fixedly mounted on the outer side of the outer barrel, a base is fixedly connected to the inner sides of the first connecting blocks, a first discharge pipe is mounted on one side of a first screening disc, and a second discharge pipe is mounted on one side of a second screening disc. The bottom of the collecting hopper is connected with a third discharging pipe, and the first screening disc filtering holes are larger than the second screening disc filtering holes. According to the utility model, through the reciprocating rotary motion of the first screening disc and the second screening disc, the motion range of dry sand on the screening surface is expanded, so that the dry sand can be distributed more uniformly, local accumulation is avoided, and the screening comprehensiveness is improved; and in cooperation with a transmission structure of a gear ring and a driving gear, a spring can guarantee the stability and the buffering effect of the structure, the first screening disc, the second screening disc and the collecting hopper are provided with a first discharging pipe, a second discharging pipe and a third discharging pipe correspondingly, dry sand with different particle sizes can be collected and discharged conveniently, and convenience of follow-up treatment is improved.
