Electric direct drive toothed roller continuous crushing device in the conveying and unloading area of ​​fully mechanized mining face

Abstract

The invention relates to the field of coal mine underground fully-mechanized mining face transportation, in particular to an electric direct drive toothed-roll type continuous crushing device for fully mechanized mining face transportation unloading zone, and aims to solve the problem of lump coal blockage at a face conveyor unloading point and a loader entry point. The related electric direct drive toothed-roll type continuous crushing device for fully mechanized mining face transportation unloading zone comprises a crushing device assembly and a hydraulic control system, wherein the crushing device assembly comprises a fixed base, a rotary base, a rotary shaft, a rocker arm, an electric direct drive crushing toothed roll, a track plate and a limiting block; the fixed base is fixed on face conveyor equipment; the rotary base is mounted on the fixed base through the rotary shaft; the rotary base is hinged to the rocker arm; the electric direct drive crushing toothed roll is integrally welded with a telescopic beam of the rocker arm; the hydraulic control system comprises a perpendicular swinging cylinder, a rocker arm telescopic cylinder, a horizontal swinging cylinder and a steering valve group. The electric direct drive toothed-roll type continuous crushing device is compact in structure and simple to operate, contributes to the high-yield and high-efficiency work to achieve continuous mining, and reduces the labor intensity and unsafe factors during manual crushing of lump coals.

Description

[0001] Technical field: [0002] The invention relates to the mining and conveying field of fully-mechanized mining working faces under coal mines, in particular to an electric direct-drive gear-roller type continuous crushing device in the conveying and unloading area of ​​fully-mechanized mining working faces. [0003] Background technique: [0004] During the mining process of medium-thick coal seam, due to the comprehensive influence of periodic pressure and mining disturbance, large pieces of coal on the working face collapse periodically, and even collapse in pieces in severe cases. Large pieces of coal falling into the conveyor chute not only affect the normal transportation of the coal flow, but also when it reaches the conveyor head, it is difficult to unload at the unloading point of the conveyor, even if it is unloaded to the reloader, it is difficult to enter the reloader entry point In the box-type conveying trough, it is easy to cause severe accumulation and block...
