[0039] Referring to the accompanying drawings, a dust suppression and dust collection device for a tunneling and anchoring machine includes a lower support plate 1. The projection of the lower support plate 1 in the top view is rectangular, and the lower support plate 1 is provided with four corners on its lower side with wheels 2.

[0040] The lower support plate 1 is fixedly provided with a handrail frame 3, and the handrail frame 3 is provided with a controller 4;

[0042] The rear of the lower support plate 1 is fixedly provided with a rear support frame 6, and the top of the rear support frame 6 is fixedly provided with a controllable spray dust suppression mechanism 7.

[0043] The controllable spray dust suppression mechanism 7 includes an upper auxiliary side plate 8, a core tube 10 fixedly mounted on the lower side of the upper auxiliary side plate 8, the core tube 10 being vertically arranged, and the lower opening of the core tube 10 contracting inward to form a contraction section 11. A lower hinge seat 12 is fixedly mounted on the outer edge of the lower opening of the contraction section 11. The number of lower hinge seats 12 is several and they are evenly arranged along the outer edge of the lower opening of the contraction section 11.

[0044] A manual hydraulic cylinder 13 is fixedly installed on the upper side of the upper auxiliary side plate 8. The core of the manual hydraulic cylinder 13 is fixedly installed on the upper side of the upper auxiliary side plate 8. The telescopic part of the manual hydraulic cylinder 13 extends downward. An inverted U-shaped bracket 14 is fixedly installed at the lower part of the telescopic part of the manual hydraulic cylinder 13. The back part of the inverted U-shaped bracket 14 is fixedly connected to the lower part of the telescopic part of the manual hydraulic cylinder 13. A sliding annular plate 15 is fixedly installed at the lower end of the two wings of the inverted U-shaped bracket 14. The sliding annular plate 15 is sleeved on the core tube 10 and can slide on the core tube 10. An upper hinge seat 16 is fixedly installed at the lower edge of the sliding annular plate 15. There are several upper hinge seats 16, which are fixedly installed around the lower edge of the sliding annular plate 15.

[0045] A secondary bending arm 17 is rotatably mounted on the lower hinge seat 12. The middle bend of the secondary bending arm 17 is rotatably engaged with the lower hinge seat 12. An active transmission arm 18 is rotatably mounted on the upper hinge seat 16. The lower end of the active transmission arm 18 is rotatably engaged with one end edge of the secondary bending arm 17 via a hinge connection. A spray pipe body 19 is fixedly mounted on the other end of the secondary bending arm 17. A spray nozzle 20 is mounted on the spray pipe body 19. The number of spray nozzles 20 is several and they are evenly distributed along one end of the spray pipe body 19 to the other end.

[0046] A water storage tank 21 and a battery 22 are fixedly mounted on the upper front of the lower support plate 1. A dust extraction fan 23 is fixedly mounted on the battery 22. A rigid exhaust pipe 24 is provided at the front of the dust extraction fan 23, and an exhaust pipe 25 is fixedly mounted at the rear of the dust extraction fan 23, extending to the core pipe 10. The middle part of the rigid exhaust pipe 24 is fixedly mounted on the water storage tank 21, and an exhaust hood 26 is fixedly mounted at the front end of the rigid exhaust pipe 24. A water pump 27 is fixedly mounted on the water storage tank 21. The water pump 27 is connected to the spray pipe 19 via a pipeline.

[0047] The controller 4 is electrically connected to the battery 22, the controller 4 is electrically connected to the dust extraction fan 23, and the controller 4 is electrically connected to the water pump 27.

[0048] I. Equipment relocation and positioning:

[0049] Since the lower support plate 1 is equipped with four corners of the lower side with traveling wheels 2, and the lower support plate 1 is fixedly equipped with a handrail frame 3 on the rear side, the operator can push the equipment through the handrail frame 3 and use the traveling wheels 2 to move the entire dust suppression and dust collection equipment of the tunneling and anchoring machine to the front position of the tunneling and anchoring machine.

[0050] II. Switching from inactive to active state:

[0051] Adjustment of position 19 on spray nozzle:

[0052] When not in use, the manual hydraulic cylinder 13 is in the retracted state, the spray pipe 19 is in a horizontal position, and the spray nozzle 20 is facing downwards. When it is necessary to switch to the operating state, the operator operates the manual hydraulic cylinder 13.

[0053] The core of the manual hydraulic cylinder 13 is fixedly mounted on the upper side of the upper auxiliary side plate 8, and the telescopic part extends downward. An inverted U-shaped bracket 14 is fixedly mounted on the lower part of the telescopic part. As the manual hydraulic cylinder 13 extends, the inverted U-shaped bracket 14 moves downward.

[0054] The lower ends of the two wings of the inverted U-shaped bracket 14 are fixed with sliding annular plates 15. The sliding annular plates 15 are sleeved on the core tube 10 and can slide on it. At this time, the sliding annular plates 15 will move downward as the inverted U-shaped bracket 14 moves downward.

[0055] Several upper hinge seats 16 are fixedly provided at the lower edge of the sliding annular plate 15. A secondary bending arm 17 is rotatably provided on the lower hinge seat 12, and an active transmission arm 18 is rotatably provided on the upper hinge seat 16. The lower end of the active transmission arm 18 and one edge of the secondary bending arm 17 are connected by a hinge. As the sliding annular plate 15 moves downward, the active transmission arm 18 drives the secondary bending arm 17 to rotate. The middle bend of the secondary bending arm 17 and the lower hinge seat 12 rotate and engage. The spray pipe 19 fixed at the other end of the secondary bending arm 17 changes from a horizontal state to a vertical state, and the several spray pipes 19 thus form a spray area.

[0056] Spraying operation:

[0057] The controller 4 is electrically connected to the battery 22, and also electrically connected to the water pump 27. The water pump 27 is connected to the spray pipe 19 via a pipeline. The operator uses the controller 4 to start the water pump 27.

[0058] Since a water storage tank 21 is fixedly installed on the upper front of the lower support plate 1, the water pump 27 draws water from the water storage tank 21 and transports the water through the pipeline to the spray pipe 19. The spray pipe 19 is equipped with several spray nozzles 20, and water is sprayed out from the spray nozzles 20 to form a spray effect.

[0059] Dust extraction procedure:

[0060] The controller 4 is electrically connected to the dust extraction fan 23, and the battery 22 provides power to the dust extraction fan 23.

[0061] The dust extraction fan 23 has a rigid exhaust pipe 24 at the front, with the middle section of the rigid exhaust pipe 24 fixedly mounted on the water storage tank 21. An exhaust hood 26 is fixedly mounted at the front end, and an exhaust pipe 25 is fixedly mounted at the rear, extending to the core pipe body 10. The operator starts the dust extraction fan 23 using the controller 4. Dust-laden air is drawn into the rigid exhaust pipe 24 by the exhaust hood 26, and then enters the core pipe body 10 through the exhaust pipe 25.

[0062] Dust-laden air is drawn into a spray area formed by several spray pipes 19. The dust is settled when it encounters the spray. The mixture of water and dust after settling then enters the wastewater pool 5, which is located in the upper rear part of the lower support plate 1.

[0063] III. Post-use procedures:

[0064] After the dust suppression and vacuuming work is completed, the operator operates the manual hydraulic cylinder 13 to shorten it.

[0065] As the manual hydraulic cylinder 13 shortens, the inverted U-shaped bracket 14 moves upward, causing the sliding annular plate 15 to move upward.

[0066] When the sliding annular plate 15 moves upward, the active transmission arm 18 drives the secondary bending arm 17 to rotate. The middle bending part of the secondary bending arm 17 and the lower hinge seat 12 rotate and cooperate. The spray pipe 19 fixed at the other end of the secondary bending arm 17 changes from a vertical state to a horizontal state, which facilitates the cleaning of the spray nozzle 20 on the spray pipe 19.

[0067] Highly efficient dust suppression: The controllable spray dust suppression mechanism 7 in the equipment is ingeniously designed. When switching from a non-use state to an use state, the spray pipe 19 can change from a horizontal to a vertical state to form a spray area. The spray pipe 19 is equipped with multiple spray nozzles 20. This multi-nozzle design allows for a wider spray coverage area, enabling more efficient contact with dust-laden air and improving dust suppression efficiency.

[0068] The dust extraction fan 23 draws the dust-laden air into the spray area, ensuring that the dust is fully mixed with the spray, further enhancing the dust suppression effect.

[0069] To prevent clogging and ensure continuous dust suppression: When not in use, the spray tube 19 is horizontal and the spray nozzle 20 is downward. This design prevents dust from entering the spray nozzle 20 and causing clogging when not in use. This ensures that the spray nozzle 20 can spray normally the next time the equipment is used, thus ensuring the continuity of the dust suppression function.

[0070] Effective dust extraction path: The dust extraction fan 23 forms an effective dust extraction path through the rigid exhaust pipe 24 and the exhaust hood 26. The exhaust hood 26 can accurately target the front of the excavator and anchor machine, effectively sucking in the generated dust and preventing it from spreading to the surrounding environment.

[0071] The exhaust duct 25 extends to the core duct body 10, allowing the sucked-in dust to be guided to a suitable position to combine with the spray dust suppression area, thereby improving the overall dust suction and dust suppression synergy of the equipment.

[0072] Easy to operate: The equipment is relatively easy to operate. The controller 4 centrally controls the functions related to the operation of the water pump 27, the dust extraction fan 23, and the manual hydraulic cylinder 13 through electrical connections to each component. The operator only needs to operate the controller 4 on the handrail frame 3 from one control position to realize various function switching of the equipment, such as spraying, dust extraction, and adjustment of the position of the spray pipe 19.

[0073] Excellent mobility and adaptability: The lower support plate 1 has four wheels 2 at its four corners, which gives the equipment excellent mobility. It can be easily moved to different working positions in front of the tunneling and anchoring machine, adapting to different working scenarios and improving the equipment's applicability.

[0074] Easy to clean and maintain: After use, the spray tube 19 can be returned to a horizontal position, making it easy to clean the spray nozzle 20. This design takes into account the maintenance needs of the equipment, reduces the difficulty of equipment maintenance, helps to extend the service life of the equipment, and reduces production delays caused by equipment failure or performance degradation.

[0075] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
