[0036] In this embodiment: The monitoring component 401 includes an image acquisition module, which includes a number of high-resolution industrial cameras for capturing the optical characteristics of the coal surface in real time, a multi-spectral light source module configured with a near-infrared LED array that can emit wavelengths of 850 nm, 940 nm, and 1450 nm, and alternately irradiates the coal surface at a preset frequency, and an image processing unit for calculating the reflection intensity ratio R of light of different wavelengths on the coal surface 1450 / R 940 , a humidity calculation module that maps the reflectance ratio to the coal moisture content value through a pre-trained support vector machine model, an early warning execution module that triggers the pressure-regulating and flow-splitting pump set 302 to adjust the spray pressure of the nozzle 304 when the moisture content exceeds the preset threshold, and a data communication module that uploads the humidity data to the cloud monitoring platform in real time through the LoRa wireless protocol.

[0037] In this embodiment: The multi-spectral light source module adopts a combination structure of a polarizing plate and a diffuser plate to eliminate specular reflection interference.

[0038] The humidity data of coal blocks Select bituminous coal with a particle size of 20-50 mm, crush it into 6 groups (100 kg per group), use the spray humidification method to control the humidity of each group to 5%, 8%, 10%, 12%, 15%, and 18%. Install a dust detector 1 m downwind of the loading point of the transfer machine. Each group of samples is continuously transported at a speed of 2 m / s for 10 minutes, and record the peak concentration and average concentration of PM10 and PM2.5. Weigh the coal sample and the power consumption of the transfer machine motor before and after transportation, and calculate the absolute weight gain: ΔW = Wwet - Wdry. Calculate the energy consumption per ton-kilometer: E = (P×t) / (W×L) (P = motor power, t = running time, W = coal weight, L = transportation distance). Cost accounting, the electricity price is calculated at 0.8 yuan / kWh for energy consumption cost, the operation cost of the dust removal equipment is calculated at dust concentration × 0.15 yuan / mg. A dust suppression system needs to be arranged for safety and environmental protection considerations in the dust construction environment, and the equipment wear cost increases by 0.3% for every 1% increase in humidity; Referring to Table 1, it can be seen that when the humidity of coal blocks is in the range of 10% to 15%, the dust and cost coefficients are the best.

[0039] Table 1 shows the operating costs of a continuous transportation walking-type transfer machine in an open-pit coal mine Coal sample humidity (%) Dust concentration (mg / m³) Weight increase (%) Energy consumption per ton-kilometer (kWh / t·km) Increase in comprehensive cost (%) Dust-cost balance coefficient* 5 92.5±4.2 0 0.29 Base value (100%) - 8 68.2±3.4 3 0.32 110% 0.82 10 40.0±2.1 6.5 0.36 118% 1.25 12 23.0±2.6 9.2 0.41 127% 1.47 15 18.0±3.3 14 0.48 142% 1.33 18 15.0±3.3 18.5 0.57 175% 0.95 20 16.0±2.1 22.7 0.63 192% 0.71 The working principle of the present invention: When using this device, first, the body 100 of the transfer locomotive needs to be moved to a suitable position. The discharge end of the feeding equipment is covered by the feeding chute 203 on the feeding dust-proof cover 202, so as to avoid the generation of dust when the coal blocks fall. The dust-proof curtain 204 is used in the feeding chute 203 to block part of the overflowing dust. The coal blocks fall onto the receiving conveyor 200 and can be covered by the sealed dust-proof cover 201 during the movement to avoid the diffusion of dust. In the middle of the receiving conveyor 200, the three-component flow pipe 303 and the nozzle 304 are used to spray and humidify the coal blocks to increase the moisture content of the coal blocks, so as to ensure that no dust is generated during the subsequent transportation of the coal blocks. The spraying of the flow pipe 303 and the nozzle 304 is controlled by the pressure-regulating and flow-dividing pump group 302, and the spraying water pressure of the nozzle 304 can be adjusted, so as to adjust the moisture content of the coal blocks in real time as needed. The submersible pump in the water tank 300 supplies water to the pressure-regulating and flow-dividing pump group 302 through the water delivery pipe 301 and is divided into three flow pipes 303 through the pressure-regulating and flow-dividing pump group 302. In order to ensure the full infiltration of the coal blocks, the driving motor 307 is started. The output end of the driving motor 307 drives the rotating shaft 305 and the stirring claws 306 to rotate on the receiving conveyor 200 to stir the coal blocks. The water infiltrated and leaked in the receiving conveyor 200 is recovered by the filter recovery water tank 500. In the filter recovery water tank 500, the water is collected into the metal cover 508 through the water collecting plate 504. The filter membrane 510 in the metal cover 508 is used to filter the water, and the water penetrates through the water seepage holes 509 to the outside of the metal cover 508. A liquid level sensor 503 is arranged in the filter recovery water tank 500. When the water level is appropriate, the recovery pump 501 is started. The recovery pump 501 transports the water to the water tank 300 through the recovery water pipe 502 to realize the recycling. During maintenance, the metal cover 508 can be taken out of the filter recovery water tank 500 by rotating the support plate 507 through the handle 512. The sealing gasket 511 and the fixing bolts 513 ensure the fixing and sealing of the support plate 507. The coal blocks transported by the receiving conveyor 200 will be transported to the surface of the transfer conveyor belt 103 on the fixed transport rack 101 and the rotating transport rack 102. Starting the hydraulic telescopic rod 600 can drive the rotating transport rack 102 to rotate at one end of the fixed transport rack 101 to realize the lifting of one end of the transfer conveyor belt 103, which is convenient for the device to transfer and transport the coal blocks to different transport equipment. The rotating transport rack 102 realizes the rotating effect through the connecting plate 105 and the rotating shaft 106. The monitoring component 401 is used to monitor the humidity of the coal blocks on the transfer conveyor belt 103.
