[0025] In this embodiment, the mining sand and gravel aggregate screening and transportation device is a device used for aggregate screening and transportation on-site such as mines and construction sites. Its working principle is to screen the original stone through the screen on the vibrating screen plate, separate the aggregates of different particle sizes, and then transport them to the destination through conveying equipment such as conveyor belts or bucket belt conveyors. The method of using the mining sand and gravel aggregate screening and transportation device is as follows: pour the original stone into the feed hopper 8, and these original stones will enter the upper screen plate 9, and then the upper screen plate 9 and the lower screen plate 10 are vibrated by the vibration motor 4 to screen, separate the aggregates of different particle sizes, and transport the screened aggregates to the required location by conveying equipment such as conveyor belts 3 or bucket belt conveyors. Workers need to regularly clean and maintain components such as the upper screen plate 9, the lower screen plate 10 and the conveyor belt 3 to ensure the normal operation of the equipment. During use, attention should be paid to regular inspections of the equipment, timely detection and resolution of possible faults, and safe operation of the equipment.
[0026] like Figure 1 and Figure 2 As shown, the support rod 11 is fixedly connected to the side plate 19, the mounting frame 12 is fixedly connected to the support rod 11, the dust suppression nozzle 14 is fixedly connected to the mounting frame 12, the water pipe 16 is plugged into the dust suppression nozzle 14, the water pipe 16 is fixedly installed inside the mounting frame 12, the water pipes 16 inside the mounting frames 12 on both sides are connected to each other, the water pipe 16 is plugged into the high-pressure water pump 17, the high-pressure water pump 17 is fixedly installed on the outside of the support column 7, and the high-pressure water pump 17 can be supplied with water by a water tank 18 or by an external water source connected to the water pipe 16 on the high-pressure water pump 17.
[0027] Preferably, through the arrangement of the dust suppression nozzle 14, the mounting frame 12, the water pipe 16, the high-pressure water pump 17 and the water tank 18, when the upper sieve plate 9 and the lower sieve plate 10 are vibrated and screened by the vibration motor 4, the dust in the stone will often be shaken up due to the vibration, causing dust. At this time, the worker needs to power the high-pressure water pump 17 with an external power supply, and connect the high-pressure water pump 17 with the water tank 18 filled with water through the water pipe 16. If there is a water source nearby for water supply, the high-pressure water pump 16 can be connected to the external water source through the water pipe 16. After that, the high-pressure water pump 17 can be turned on to transport water to the dust suppression nozzle 14 through the water pipe 16 in sequence, and the water is atomized through the dust suppression nozzle 14, thereby improving the dust suppression effect of the water mist.

[0029] Preferably, through the arrangement of the rotating rod 15, the rotating part 13, the dust suppression nozzle 14 and the water pipe 16, the rotating rod 15 can be rotated by the rotating parts 13 on both sides, thereby adjusting the spraying angle of the dust suppression nozzle 14 above, and since the water pipe 16 can be inserted into the rotating rod 15 through the rotating part 13, when the rotating rod 15 is rotating, it will not affect the water pipe 16 from supplying water to the dust suppression nozzle 14 on the rotating rod 15, thereby ensuring the normal operation of the dust suppression nozzle 14, and the dust suppression nozzles 14 on both sides of the feed hopper 8 can suppress the dust generated during feeding, thereby reducing the impact of stone dust on the environment and workers' health.
