Problems solved by technology
[0003] In related technologies, the volume of the dust suppression equipment is fixed, and the dust suppression effect of the smaller dust suppression equipment is poor, while the larger equipment occupies a large area and is not easy to transport. The speed is slow, so that the time of dust reduction will increase, resulting in low dust reduction efficiency, and it is difficult to adjust the angle of the nozzle, which will affect the use effect of dust reduction equipment.
In addition, most of the dust suppression equipment is directly used for dust suppression through water, and cannot be used in spaces where water cannot be used, which is inconvenient to use and has a single function

The invention discloses a dust suppression device for an opencast coal mine. The dust suppression device for an opencast coal mine comprises: a base, a telescopic assembly, a pipeline and an air extraction assembly; a support cylinder is arranged on the base, and a connecting cylinder is arranged on the support cylinder and the movable cylinder It is used to connect the support cylinder and the movable cylinder, the movable cylinder can move in the first position and the second position along its length direction, the connecting cylinder includes an upper cylinder section and a lower cylinder section, and the upper cylinder section and the lower cylinder section are pivotally connected, The outer peripheral surface of the support cylinder is provided with a first through hole, the outer peripheral surface of the movable cylinder is provided with a second through hole, the pipe is arranged in the telescopic assembly, the nozzle assembly and the movable cylinder are pivotally connected, and the outlet of the nozzle assembly and the pipe is provided. The liquid ends are communicated, and the air extraction assembly is arranged above the movable cylinder. The dust-reducing device of the embodiment of the present invention can perform dust-reducing operations in multiple directions, and the spraying angle is adjusted by the nozzle assembly, thereby improving the dust-reducing effect of the dust-reducing device.
Description
technical field [0001] The invention relates to the field of coal mine dust reduction equipment, in particular to a dust reduction device for opencast coal mines. Background technique [0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When mining in coal mines, a large amount of dust will be generated. The dust contains many substances that are harmful to human health. The inhalation of dust and other harmful substances into the human body seriously affects the health of workers. [0003] In the related art, the volume of the dust suppression equipment is fixed, the dust suppression equipment with a smaller size has a poor dust suppression effect, and the larger equipment occupies a large area and is not easy to handle. The speed is slow, so that the dust reduction time increases, resulting in low dust reduction efficiency, and it is difficult to adjust the...
