[0020] Please see Figure 1-5 A closed cab for underground mining trucks includes a cab 1, a driver's outer frame 2 located on the upper side of the cab 1, a roof 3 located on the upper side of the driver's outer frame 2, a door 4 located on one side of the driver's outer frame 2, and glass windows 5 located around the outer perimeter of the driver's outer frame 2. A dust suppression spraying mechanism 6 is located on the top of one side of the driver's outer frame 2, and a water supply mechanism is located on one side of the driver's outer frame 2, which is connected to the dust suppression spraying mechanism 6. One side of the dust suppression spraying mechanism 6 is connected to one side of the roof 3. This closed cab, through the cab 1, driver's outer frame 2, roof 3, door 4, and glass windows 5, creates a sealed space, preventing underground dust and harmful gases from entering and creating a safe and comfortable operating environment for the driver. The top dust suppression spraying mechanism 6 is connected to the side water supply mechanism, which can promptly atomize and suppress dust in front of the cab, improving visibility.
[0021] The dust suppression spraying mechanism 6 includes a side-opening box 10 connected to the top outer side of the driver's outer frame 2, a swing spraying mechanism disposed within the side-opening box 10, and a dustproof mechanism disposed on the outside of the side-opening box 10. The dustproof mechanism can cover one side of the side-opening box 10. The swing spraying mechanism is integrated into the side-opening box 10 at the top outer side of the driver's outer frame 2, making full use of space and not affecting driving operations, and can perform multi-angle dust suppression operations in front of the cab.
[0022] The dustproof mechanism includes multi-stage electric push rods 17 respectively installed on both sides of the side opening box 10, a top plate 18 connected to the output ends of the two multi-stage electric push rods 17, and a dustproof side plate 19 connected to the lower side of the top plate 18. The dustproof side plate 19 is slidably engaged with one side of the side opening box 10, and the top plate 18 is located above the side opening box 10. The top plate 18 and the dustproof side plate 19 are driven by the multi-stage electric push rods 17 to open and close, facilitating the activation and storage of the swing spray mechanism. The slidable engagement of the dustproof side plate 19 with the side opening box 10 can isolate dust and debris from the well, preventing them from entering the side opening box 10 and clogging the atomizing nozzles 14, thus reducing equipment maintenance costs.
[0023] The oscillating spray mechanism includes a servo motor 15 mounted on one side of the side-opening box 10, a spray pipe 11 connected to the output shaft of the servo motor 15 and located inside the side-opening box 10, multiple atomizing nozzles 14 communicating with the outer wall of the spray pipe 11, a rotating shaft 16 connected to one end of the spray pipe 11, a connecting pipe 13 communicating with the outer wall of the spray pipe 11, and a flexible hose 12 communicating with one end of the connecting pipe 13. One end of the rotating shaft 16 is rotatably connected to the inner side of the side-opening box 10 via a bearing. The multiple atomizing nozzles 14 are arranged at equal intervals along the length of the spray pipe 11. By using the servo motor 15 to drive the spray pipe 11, the oscillation angle and speed can be controlled, and in conjunction with the rotation of the rotating shaft 16, the dust suppression coverage area is expanded.
[0024] The water supply system includes a water tank 7 connected to the outside of the driver's outer frame 2, a water pump 8 connected to the bottom of one side of the water tank 7, and a delivery pipe 9 connected to the outlet port of the water pump 8. One end of the delivery pipe 9 passes through the side-opening box 10 and is connected to one end of the hose 12. A water inlet is connected to the upper side of the water tank 7; the water supply tank 7, water pump 8, and delivery pipe 9 provide a water source guarantee for dust suppression operations.
[0025] Mounting plates 20 are connected to both sides of the water supply tank 7. One mounting plate 20 is spaced apart from the water pump 8. The two mounting plates 20 are bolted to the driver's outer frame 2, which realizes the stable and detachable installation of the water supply tank 7. This facilitates quick disassembly when the equipment is inspected, maintained or replaced, and ensures that the water supply tank 7 will not loosen or shift in the bumpy environment underground.
[0026] Working Process and Principle: When the enclosed cab of the underground mining truck is in operation, if the dust concentration is too high and obstructs the driver's vision, the driver can activate the control program inside the cab. This causes the multi-stage electric push rods 17 on both sides to operate synchronously, driving the top plate 18 to rise vertically, thereby pulling the dustproof side plate 19 away from the cover of the opposite side opening box 10. Subsequently, the servo motor 15 receives the command and drives the output shaft to rotate the spray pipe 11, rotating multiple atomizing nozzles 14 out of the side opening box 10. Immediately afterwards, the water pump 8 and the servo motor 15 start in tandem. The water pump 8 delivers water from the water supply tank 7 through the delivery pipe 9, hose 12, and connecting pipe 13 to the spray pipe 11. The servo motor 15 then drives the spray pipe 11 to swing regularly within the side opening box 10 around the pivot 16, causing the atomizing nozzles 14 to atomize the water flow and spray fine water mist from multiple angles, adsorbing and settling the surrounding dust and improving the driver's visibility.
[0027] When not in operation, the servo motor 15 rotates in reverse, driving the spray pipe 11 and the atomizing nozzle 14 to rotate back into the side opening box 10. At this time, the multi-stage electric push rod 17 is activated again, pushing the top plate 18 and the dustproof side plate 19 to fall. The dustproof side plate 19 slides against the side opening box 10 to form a sealed protection, preventing dust from entering and avoiding clogging of the atomizing nozzle 14 due to dust accumulation.
[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
