Mineral offset adjusting excavator

Abstract

The invention relates to hydraulic excavating equipment, and in particular relates to a mineral offset adjusting excavator which is applicable to conveying on stope faces of coal mine wells and excavation and bottom cleaning of tunnels of air return ways, for solving the problems that in the prior art the working intensity is large, the production efficiency is low, the cleaning is not thorough, offset and walking of an excavation arm main body cannot be achieved, and the like. Walking devices are arranged on two sides and the front part of the base of the excavator, an offset adjusting device is arranged at the rear part of the base, and walking and offset of the excavation arm main body are achieved. The mineral offset adjusting excavator provided by the invention is compact in structure and small in appearance size and has the characteristics of energy conservation, low noise, small pollution, high efficiency, simplicity and convenience in operation, and the like as a full-hydraulic system is adopted for control, and offset and walking of the excavator main body are also achieved. Therefore, mechanical operation of the excavator in relatively soft rock tunnel bottom plates such as shale and batt in mine wells is achieved, and the excavation and bottom cleaning speed is greatly increased.

Description

technical field [0001] The invention relates to hydraulic excavation equipment, in particular to a mining offset adjustment excavator, which is suitable for relatively soft lithology such as shale, argillaceous shale, etc. Excavation and bottom cleaning of the upward bulging part of the formed floor due to ground pressure is especially suitable for cleaning the bottom of the bulging part of the soft lithology floor under the belt conveyor hanging along the trough. Background technique [0002] In coal mine production, especially in the production process of mining face, the underground roadway is affected by factors such as ground pressure and surrounding rock stress changes. A partial upward bulging change occurs. [0003] Such a change causes the section of the roadway to shrink, which not only affects the ventilation safety of the mine, affects the driving safety of pedestrians and narrow-gauge transportation, but also affects the normal operation of the belt conveyor, w...
