AI Technical Summary

Technical Problem

During the rotary screening of existing gravel gravel screening devices, it is difficult to quickly screen the mass of materials, resulting in low screening efficiency.

Method used

A crushed stone screening device for a loader is designed, including a bucket, a screen barrel and a rotary drum. The screen barrel is equipped with a reinforcement frame, a guide groove and a dispersion mechanism. The outer peripheral side of the rotary drum is equipped with a spiral slide and an arc-shaped scraper. Through the cooperation of these structures and mechanisms, multi-channel screening and dispersion of materials are realized.

Benefits of technology

The device can efficiently screen the mass of materials and gravel, improve screening efficiency, ensure that materials and gravel can be quickly exported through the screen hole, reduce the resistance of the hollow spiral shaft to rotate and push the gravel, and prevent gravel from being stuck on the outside of the shaft.

Abstract

The invention discloses a broken stone screening device for a loader, and relates to the technical field of screening equipment, the broken stone screening device comprises a bucket connected to a lifting arm of the loader and a screen drum communicated to the back of the bucket and used for material separation, and screen holes used for filtering materials are formed in the half circumferential surface, close to the bottom of the bucket, of the screen drum; reinforcing frames are fixed to the inner side of the screen drum at equal intervals. According to the broken stone screening device for the loading machine, the loading machine drives an opening of the bucket to rotate upwards, materials are guided into a channel between the screen drum and the rotary drum, meanwhile, the driving mechanism drives the stone inlets which are distributed in a staggered and equal-included-angle mode through the rotary drum to scrape broken stones, and the materials can be conveniently screened from multiple channels; when the dispersing frame at the front end of the middle shaft rod and the material stirring rod at the tail end of the middle shaft rod move in the wave-shaped fluctuation cavity, the dispersing mechanism can disperse shoveled or extruded materials in a reciprocating mode through reciprocating fluctuation, and it is ensured that the device can efficiently screen clustered materials and broken stones.
