AI Technical Summary

Technical Problem

Traditional vibratory ore feeders are prone to jamming when dealing with unevenly sized ore pieces after blasting, containing a large number of large pieces of ore. They also have a low degree of automation and pose significant safety hazards.

Method used

An external hydraulic crushing and anti-blocking ore discharge system is adopted, which includes an ore discharge device, a dredging mechanism, a pressure detection unit, and a control unit. By combining pressure detection and image acquisition, the dredging mechanism can be remotely controlled to perform crushing, turning, or flipping actions to solve the problem of large ore blockage.

Benefits of technology

It has achieved automated ore dredging, avoiding the safety hazards of secondary blasting and manual handling, improving the intelligence and ease of operation of the equipment, and reducing labor intensity.

Abstract

This invention relates to the field of mining equipment technology, and particularly to an external hydraulic crushing and anti-blocking ore discharge system. The system includes an ore discharge channel, an ore discharge device located at the outlet of the ore discharge channel, a clearing mechanism located above the ore discharge device for crushing, shifting, or flipping obstructions within the ore discharge channel, a pressure detection unit located inside the ore discharge device for collecting pressure changes and pressure duration data of the ore located on the ore discharge device, and a control unit located outside the ore discharge channel for receiving electrical signals from the pressure detection unit and controlling the clearing mechanism to operate when both the pressure change and pressure duration exceed preset values; and a power module for providing power to the clearing mechanism, pressure detection unit, and control unit. This invention effectively detects pressure changes and pressure duration data of the ore discharge device through the pressure detection unit and determines the blockage situation based on preset values, executing corresponding clearing actions to effectively solve the problem of large ore blockages.
