Description

Technical Field

[0001] This utility model relates to the field of coal mine loaders, and in particular to a dust suppression mechanism for coal mine loaders. Background Technology

[0002] Mining excavator loaders are mechanical equipment used in narrow tunnel mining environments. They are mainly used in the crushing, conveying, and loading of crushed stone in mines such as phosphate mines, iron mines, and coal mines and in tunnel engineering. During coal mining, the operation of loaders generates a large amount of dust, which not only endangers the health of workers but may also cause explosions.

[0003] Traditional dust suppression methods (such as water spraying and ventilation) suffer from uneven coverage, low dust suppression efficiency, and water waste. Furthermore, they are inconvenient to use according to different loader specifications. Existing dust suppression equipment often has a fixed structure, making it difficult to adapt to the dust control needs of different working conditions, and it lacks dust collection and filtration functions. Therefore, a dust suppression mechanism for coal mine loaders is proposed to solve the problems mentioned in the background technology. Utility Model Content

[0004] The technical problem this utility model aims to solve is to overcome the existing defects and provide a dust suppression mechanism for coal mine loaders. This mechanism employs an adjustable spray pipe and a multi-angle atomizing nozzle design, enabling flexible adaptation to different operating scenarios and achieving efficient dust suppression. It integrates a negative pressure dust collection and activated carbon filtration system, simultaneously suppressing dust and collecting and purifying it, significantly improving the working environment. This effectively solves the problems of uneven coverage and low efficiency associated with traditional dust suppression methods, significantly enhancing the safety and environmental friendliness of coal mine operations, and effectively addressing the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression mechanism for a coal mine loader, comprising a fixing plate and a dust suppression unit:

[0006] Fixed plate: An adjusting seat is fixed on the top surface, and an adjusting rod is slidably installed inside the adjusting seat. The front end of the adjusting rod is connected to the middle of the rear side of the fixed seat. Mounting units are provided on both sides of the top surface of the fixed plate, and locking plates are provided inside the mounting units.

[0007] Dust suppression unit: includes a liquid pump, a dust suppression liquid tank, a spray pipe, an atomizing nozzle, a frame, and a motor. The frame is located on the left side of the fixed base. The motor is fixed on the surface of the frame. The output shaft of the motor is connected to the left end of the spray pipe that rotates inside the fixed base. An atomizing nozzle is installed on the spray port on the front side of the spray pipe. The liquid pump is fixed on the top surface of the dust suppression liquid tank. The outlet pipe of the liquid pump is connected to the inlet on the top surface of the spray pipe.
