Fault-free drag and suction device for coal face

Abstract

The invention discloses a fault-free drag and suction device for a coal face. The fault-free drag and suction device for the coal face comprises a motor, a water pump, a center shaft and a drag and suction component, wherein the motor is arranged above the water pump, the drag and suction component is arranged at a suction inlet below the water pump, the motor and the water pump are arranged coaxially relative to the center shaft, and thus the fault-free drag and suction device is easier to mount and use. The drag and suction device is arranged at the suction inlet below the water pump so that a large quantity of impurities, such as crushed coal and crushed stone, affecting operation of the water pump can be effectively filtered out, using risks of the water pump are reduced, and the service life is prolonged. An inductive starting and stopping component is mounted on the drag and suction component, and automatic starting and stopping of the water pump are achieved according to preset starting and stopping liquid levels, so that the automation degree is improved, and the labor intensity of field personnel is relieved.

Description

technical field [0001] The invention relates to a coal mine machine, in particular to a trouble-free raking device for a coal mine excavation face. Background technique [0002] At present, most domestic coal mine mining face wastewater is discharged by vertical pipeline pump drainage operation. This pump has the characteristics of small footprint, simple and convenient installation, etc.; but the disadvantages are also prominent, because there will be a large number of high hardness in the mining face area during work. The broken cinders, gravel, etc. fall to the ground. Due to the small volume of the pump itself, this kind of waste water mixed with sundries is easy to cause blockage or damage to the pump during the operation of the pump. As the water level drops, there will be a large amount of waste water. Wastewater containing sundries cannot be discharged and is deposited in the roadway, which brings inconvenience to production [0003] Therefore, how to quickly and ef...

Due to the small size of the pump itself, this kind of waste water mixed with sundries is easy to cause blockage or damage to the pump during the operation of the pump. As the water level drops, there will be a lot of waste water. Wastewater containing sundries cannot be discharged and is deposited in the roadway, which brings inconvenience to production
