Description

Technical Field

[0001] The utility model relates to the technical field of mine environment monitoring, in particular to a mine environment dust detection device. Background Art

[0002] In recent years, with the increasing mechanization, automation, and intelligence of mining operations, dust pollution has become increasingly serious. To further improve clean production and occupational health in mines, pollution control is necessary. Among intelligent dust suppression systems, spray dust suppression has become one of the most widely used dust suppression technologies in mines due to its simple operation, low cost, and significant dust reduction efficiency.

[0003] Mines are mined underground, with ore transported to surface ore yards by transport vehicles, and waste rock transported to waste rock yards by transport vehicles. Dust is generated during loading and unloading at ore and waste rock yards, polluting the yard environment. Therefore, it is necessary to detect the environment of the ore and waste rock yards so that dust reduction operations can be carried out in a timely manner. The existing technology is to set up dust detectors around the yard to detect dust, but the position of this dust detector is fixed and far away from the unloading and loading positions. When dust is detected, the dust has already spread to a certain range. At this time, dust reduction needs to be carried out over a large area, wasting water resources. In addition, the detection position of the dust detector with a fixed structure cannot be changed, the detection range is small, and it is inconvenient to use. Utility Model Content

Dust reduction treatment only needs to be performed in a small area, thereby reducing the waste of water resources; the position of the dust detector can also be adjusted to increase the detection range. It is easy to use and can effectively solve the problems in the background technology.

[0006] As a preferred technical solution of the present invention, an electric push rod is provided at the bottom of the mounting seat, and a fixed end of the electric push rod is mounted on a mounting frame of the external dust reduction equipment.

[0007] As a preferred technical solution of the present invention, a servo motor is provided on the mounting seat, and the middle portion of the slide rail is mounted on the output shaft of the servo motor.

[0008] As a preferred technical solution of the present invention, a plane bearing is provided on the mounting seat, and a support plate for supporting the slide rail is provided on the upper surface of the plane bearing.

[0009] As a preferred technical solution of the present invention, the central axis of the plane bearing coincides with the central axis of the servo motor output shaft.
