Description

Technical Field

[0001] The utility model relates to the technical field of tunneling machines, in particular to a dust reduction coal mine tunneling machine. Background Art

[0002] my country is a large coal-producing country with numerous coal mines of all sizes. With the rising prices of energy sources such as oil and natural gas, coal has become a popular energy source in China, and the demand for it will inevitably be huge in the future, which will stimulate the rapid development of the coal mining industry. With the government's attention to the safety issues of coal mining, it will become possible to gradually achieve fully mechanized production in the future, which will inevitably further increase the demand for coal mine roadheaders.

[0003] Among them, the tunnel boring machine is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a transfer mechanism. The working mode of the tunnel boring machine is: as the traveling mechanism moves forward, the cutting head in the working mechanism continuously crushes the rock and transports the crushed rock away. The crushing process drives the transmission shaft to rotate through the action of an external power source, and the transmission shaft drives the tunneling cutter head to rotate. The rotating tunneling cutter head is used to carry out coal mine excavation work. During the process of the tunneling cutter head crushing the rock, a large amount of dust will be generated. The dust affects the construction environment. When the dust concentration in the mine is too high, it is inconvenient for workers to enter. For this reason, we propose a dust reduction coal mine tunnel boring machine. Utility Model Content

[0004] The utility model aims to provide a dust reduction coal mine boring machine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dust reduction coal mine tunneling machine, comprising a tunneling machine head, a dust reduction component, the dust reduction component allows the dust generated when the tunneling machine head is working to fall, the dust reduction component is fixedly connected to the tunneling machine head, and an adjustment component, the adjustment component is used to change the use position of the dust reduction component, and the adjustment component is fixedly connected to the tunneling machine head.

[0007] Preferably, a sealing plug is installed in the water tank.

[0008] Preferably, a transmission shaft is rotatably connected to the tunneling machine head, and a tunneling cutter head is fixedly connected to the transmission shaft.

[0009] Preferably, a connecting plate is fixedly connected to the tunnel boring machine head, and a mounting hole is processed in the connecting plate.

[0010] Preferably, the adjustment assembly includes a bracket, the bracket is fixedly connected to the tunnel boring machine head, a rotating shaft is rotatably connected in the bracket, a storage plate is fixedly connected to the rotating shaft, the storage plate and the connecting pipe are fixedly connected, a gear is fixedly connected to the rotating shaft, a tooth plate is meshingly connected to the gear, a hydraulic rod is fixedly connected to the tooth plate, and the hydraulic rod is fixedly connected to the tunnel boring machine head.

[0011] Preferably, a protective shell is provided on the storage plate, bolts are sleeved in the protective shell, and the bolts are threadedly connected to the storage plate.

[0012] Preferably, a mesh plate is fixedly connected in the protective shell.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. When using a tunneling machine head for coal mining, the water in the water tank is introduced into the telescopic pipe under the action of the water pump. The water flows along the telescopic pipe into the connecting pipe and is finally discharged through the atomizing nozzle. The atomized water comes into contact with the dust in the air, and the surface tension of the water is used to drive the dust to fall, thereby achieving the dust reduction effect around the tunneling machine head.

[0015] The water source in the water tank is introduced into the atomizing nozzle through a water pump, and the water pressure is increased by the water pump to facilitate the atomization of the water source. The atomized water source spreads over a large area, and the atomized water source comes into contact with the dust, thereby reducing the dust generated during the excavation process and reducing the dust concentration in the mine when the tunnel boring machine head is working. The use of telescopic pipes facilitates the adjustment of the position of the connecting pipe. Multiple atomizing nozzles are evenly distributed along the connecting pipe to expand the dust reduction range around the tunnel boring machine head.

[0016] 2. When dust is reduced around the tunneling cutter head, start the hydraulic rod on the tunneling machine head, which drives the tooth plate to move horizontally. The tooth plate drives the gear to rotate through meshing, and the gear drives the shaft to rotate in the bracket. At the same time, the shaft drives the placement plate to move, and the placement plate drives the connecting pipe to move together.

[0017] Through the reciprocating motion of the hydraulic rod, gears and toothed plates are used as transmission, and the connecting tube on the placement plate swings in an arc shape. At this time, the water source emitted from the atomizing nozzle swings in a fan shape, and the atomized water source contacts the surrounding dust, expanding the dust reduction range of the atomizing nozzle. When the hydraulic rod stops working, the toothed plate does not move, and the inclination angle of the placement plate can be fixed, so that dust can be reduced in a specific direction in the coal mine.
