Self-control type hole sweeping device for coal mining

Abstract

The invention is applicable to the technical field of coal mining equipment, and provides a self-control type hole sweeping device for coal mining. The self-control type hole sweeping device for coalmining comprises a gun body assembly. The gun body assembly comprises a gun body, a handheld handle, a hole sweeping pipe and a valve control piece, the handheld handle and the gun body are integrallyformed, the hole sweeping pipe is arranged at the end, far away from the handheld handle, of the gun body, the valve control piece is used for controlling the opening and closing of the hole sweepingpipe, the handheld handle and the gun body are each of a hollow structure, an air inlet pipe communicating with the handheld handle is arranged at the end, far away from the gun body, of the handheldhandle, and the hole sweeping pipe is fixed to and communicates with the end, far away from the handheld handle, of the gun body. The gun body and the handheld handle of the hole sweeping device aredesigned to be integrally formed, and the gun body and the handheld handle are each of the hollow structure, so that when an air source enters the air inlet pipe communicating with the handheld handle, the air source can flow out of an air outlet end of the hole sweeping pipe communicating with the gun body, and the hole sweeping work is carries out. Meanwhile, the valve control piece capable of adjusting the opening and closing of the hole sweeping pipe is arranged, and the valve control piece is arranged to facilitate the control over the size of the air sprayed out of the hole sweeping pipe.

Description

technical field [0001] The invention belongs to the technical field of coal mining equipment, in particular to an automatic control eye sweeper for coal mining. Background technique [0002] Coal mining technology, no matter open-pit or underground, is developing towards the remote control and automation of the production process on the basis of the high degree of mechanization that has been achieved so far. By improving the design, type selection, material, manufacturing process, inspection method and maintenance system of fully mechanized mining equipment, its production capacity and equipment utilization rate will be improved. At the same time, automation and remote control will be realized in many links such as mine hoisting, transportation, drainage, ventilation, and gas monitoring. Both underground and open-pit coal mines will realize centralized automatic management and monitoring by electronic computers. [0003] The back end of the eye sweeper currently used in th...

Problems solved by technology

[0004] The invention provides a self-controlled eye sweeper for coal mining, which aims to solve the problem that the rear end of the traditional eye sweeper is first connected with the wind belt, and then connected with the compressed air through the wind belt. The eye-catching process not only requires a high degree of cooperation between the two personnel, but also poses certain safety hazards.
