AI Technical Summary

Technical Problem

In existing automated mining equipment, when the crushing roller breaks up the coal seam, the splashing of coal particles causes the gears and toothed plates to fail to mesh, resulting in the device jamming, affecting its service life and dust suppression effect.

Method used

An automated mining equipment for working faces was designed. It adopts a structure consisting of a first fixed box, a second fixed box, a reciprocating screw, a toothed plate, and gears, combined with a cylinder, a mounting plate, a mounting platform, and a second transmission component to achieve safe rotation of the crushing roller and oscillation of the atomizing nozzle, thus preventing the equipment from jamming. The specifications of the crushing roller can be adjusted by the cylinder to improve adaptability.

Benefits of technology

It effectively avoids equipment jamming, improves transmission smoothness, extends service life, reduces the number of drive sources, and increases the applicability and practicality of the device.
