Classification and screening equipment for mine stone

Abstract

The invention belongs to the technical field of ore screening, and specifically relates to a grading and screening equipment for mine stones; it includes a cone, the top of which is inserted with a plurality of annular rings with successively increasing diameters, and the bottom of the annular ring is fixedly connected There is an operating rod, and the bottom end of the operating rod is arranged at the bottom of the truncated cone, and a plurality of annular rings are provided with channels, and the length of the channel on the annular ring of the inner ring is longer than the length of the channel on the annular ring of the outer ring. Large; the present invention sets an annular ring and an arc-shaped plate, and the arc-shaped plate can push the larger stone blocked in the channel under the action of the motor, so that the stone with a suitable diameter enters the appropriate annular ring through the channel. Make the stones between two adjacent annular rings relatively close, move the annular ring up and separate from the cone, and release the materials with gradually increasing diameter from the cone. It is used in small mines, which improves the versatility of the use environment and has little noise pollution.

Description

technical field [0001] The invention belongs to the technical field of ore screening, in particular to a grading and screening equipment for mine stone materials. Background technique [0002] Mine roadway is a general term for various underground spaces excavated in different directions, at different inclination angles, according to different sections and lengths in different rocks, serving different ranges and used for different purposes. Mine roadways are named and classified according to their spatial size, inclination direction, location, service scope and purpose. When excavating mine roads, it is necessary to reinforce the excavated mine roads to ensure the safety of the mine roads. It is necessary to use a grading and screening device to screen the excavated stones and select stones of different specifications for use. [0003] Most of the existing multi-stage screening devices are screened with screens with smaller and smaller apertures in the vertical direction fr...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing multi-stage screening devices are screened with screens with smaller and smaller apertures in the vertical direction from top to bottom, which requires that the height of the mine tunnel be large enough to ensure The spacing is more appropriate, but when excavating some low-level mines, it cannot be guaranteed that the multi-stage screening device can enter the excavated mines, and when the vibrating screen is used in the special environment of the mine, its vibration frequency Larger and more serious noise pollution, in view of this, the present invention provides a grading and screening equipment for mine stones, which can be used in mines with a small height, improves the versatility of the use environment, and has little noise pollution
