Gob Filling Machine
This machine is used for gangue filling of goaf roadways in underground coal mines. It can realize roadway backfill mining and build new-type green mines. Through backfill mining, gangue is used to replace coal, which not only improves the recovery rate of coal resources, but also realizes that gangue does not go up the well and no gangue hill is built on the ground, with significant comprehensive economic benefits. It can also be used for filling old roadways.
The filling vehicle features a short and low body, offering good stability and a wide range of applications.
The projecting belt adopts a high-power electric drum, with a projecting speed of up to 4m/s, ensuring excellent projecting performance and a long service life.
Equipped with imported hydraulic valve groups, the projecting belt is controlled by a pilot handle, enabling simple operation and high reliability.
The projecting belt is capable of lifting, rotating, telescoping, and flattening, with strong propulsive force, ensuring full-range filling of roadways, high gangue filling rate, and excellent filling effect.
The feeding and unloading mechanism has the functions of leveling, inclining, deflecting, and height adjustment, boasting strong adaptability.
A transition section is specially designed in the feeding and unloading mechanism, effectively solving the problem of smooth transition in belt lapping.
The machine supports both manual operation and video remote control. It mainly remotely controls various actions of the gangue throwing mechanism via wireless, providing a more user-friendly operation experience.
