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
Technical field: [0001] The invention relates to the field of mining and conveying of fully mechanized mining face in a coal mine, in particular to an electric direct drive toothed roller type continuous crushing device in the conveying and unloading area of fully mechanized mining face. Background technique: [0002] During the mining process of medium-thick coal seams, due to the combined influence of periodic pressure and mining disturbance, the working face sheet helps large pieces of coal to collapse periodically, and even collapse in pieces in severe cases. Large lump coal falling into the conveyor chute not only affects the normal transportation of coal flow, but also when it reaches the conveyor head, it is difficult to unload at the conveyor unloading point, and even if it is unloaded onto the loader, it is difficult to enter the loader entry point In the box-type conveying trough at the same place, it is easy to cause serious accumulation and blockage in the fan-...
