[0002] Laser coal stackers are suitable for measuring the height, length, and volume of coal piles, earthworks, or ore piles of any shape in industries such as power, coal, and metallurgy.

[0003] The laser coal counting instrument is used in dusty environments. When measuring coal piles, the instrument needs to be used to measure around the coal pile. Dust can easily adhere to the laser head, which can hinder the emission and reception of the laser and affect the measurement results. Therefore, a dustproof laser coal counting instrument is proposed. Utility Model Content

[0011] Beneficial effects

[0012] This invention provides a dustproof laser coal counting device. Compared with existing technologies, it has the following advantages:

[0013] Beneficial effects:

[0014] This invention utilizes an electric telescopic rod to move a movable plate, which in turn moves the laser coal detector to the left. The laser coal detector then moves a sliding rod to the left, which in turn moves a toothed pressure plate to the left via a connecting plate and a push rod. The toothed pressure plate, in turn, drives a rotating rod to rotate via gears. When the laser coal detector reaches the opening of the protective frame, the dustproof plate rotates and stacks on the protective frame. Laser measurement is then performed using the laser coal detector on the laser head. The electric telescopic rod is then retracted, moving the laser coal detector into the protective frame, where the dustproof plate again covers the front of the frame. This effectively conceals the laser coal detector, preventing it from being continuously exposed and accumulating dust, thus ensuring the laser coal detector can emit and receive laser signals.
