Spraying and dust-settling device for heading machine

Abstract

The invention discloses a spraying and dust-settling device which comprises a heading machine conveying belt H-shaped steel frame, a threaded connection hole is formed in the upper surface of the heading machine conveying belt H-shaped steel frame, and the inner wall of the threaded connection hole is in threaded connection with a mounting bolt. The upper surface of the heading machine conveying belt H-shaped steel frame is fixedly connected with a spraying and dust-settling equipment mounting plate through mounting bolts, and the upper surface of the spraying and dust-settling equipment mounting plate is fixedly connected with a water storage tank, a high-pressure water pump and a connecting support. According to the spraying and dust-settling device for the heading machine, the water level in the water storage tank can be controlled by arranging a valve electric device, an electromagnetic valve, floating ball water level sensors and a rubber hose, so that the water level is maintained between the heights of the two floating ball water level sensors, and a high-pressure water pump, a water conveying pipe, a water conveying coil pipe and a nozzle are arranged. Water flow can be sprayed in the heading direction of the heading machine in a curtain shape, the purpose of spraying and dust-settling in the heading process is achieved, and the dust-settling effect is good.

Description

technical field [0001] The invention relates to the technical field of roadheaders, in particular to a spray dust suppression device for roadheaders. Background technique [0002] The roadheader is a machine used to excavate roadways on flat ground. There are many types of roadheaders. They are divided into ordinary machines and tunnel boring machines according to the operating objects, and divided into open type roadheaders and shield type roadheaders according to the operation method. [0003] The cutting head of the roadheader will produce a large amount of coal dust during the excavation, which is the main source of dust in the excavation work. Although the roadheader has its own spray device, in actual work, due to the low water supply pressure of the system, serious nozzle blockage, Due to poor filtration and other reasons, the water flow is jet-shaped, and the wrapping angle and atomization effect are not ideal, resulting in the inability to effectively suppress coal ...
