Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides a spray dust suppression device for limestone mining and tunneling, including a movable frame 1 and a fixed plate 2. The movable frame 1 consists of an outer frame and a fan wheel, which facilitates the movement and adjustment of the position of the spray dust suppression device. An electric push rod 8 is fixedly installed on the bottom inner wall of the movable frame 1. The bottom of the fixed plate 2 is fixed to the top of the electric push rod 8. The fixed plate 2 is located inside the movable frame 1. A push handle 3 is fixed on one side of the movable frame 1. An easy-to-clean water storage component 4 is fixedly installed on the top of the fixed plate 2. A connecting pipe 5 is installed on one side of the easy-to-clean water storage component 4. The connecting pipe 5 can connect the atomizing nozzle 7 and the easy-to-clean water storage component 4 together. An adjusting frame is fixed on the top of the fixed plate 2. A multi-angle adjusting component 6 is installed on the adjusting frame. An atomizing nozzle 7 is fixedly installed on one side of the multi-angle adjusting component 6. The other end of the connecting pipe 5 is fixedly installed on one side of the atomizing nozzle 7.

[0029] One application of this embodiment is as follows: the dust suppression liquid is manually injected into the easy-to-clean water storage component 4. The dust suppression liquid can be water. The multi-angle adjustment component 6 is used to flexibly adjust the atomizing nozzle 7 at multiple angles, which improves the efficiency of spray dust suppression and makes the coverage of spray dust suppression wider. Then, the pusher 3 pushes the moving frame 1 to move, so that spray dust suppression can be carried out at different mining and tunneling positions. Under the action of the easy-to-clean water storage component 4, the dust suppression liquid can be pumped to the other end of the connecting pipe 5 and sprayed out by atomizing nozzle 7, which has a better dust suppression effect. After spraying, the electric push rod 8 retracts, which can drive the fixed plate 2 to move downward, reducing the space occupied by the easy-to-clean water storage component 4 and the multi-angle adjustment component 6.

[0030] The easy-to-clean water storage assembly 4 includes a first water storage tank 401 and a second water storage tank 402. The bottom of the first water storage tank 401 is fixedly installed on the top of the fixing plate 2. The bottom of the second water storage tank 402 is located on the top of the first water storage tank 401. A sealing strip 403 is fixedly installed on the inner wall of the second water storage tank 402. The sealing strip 403 is located between the first water storage tank 401 and the second water storage tank 402, which improves the sealing effect between the first water storage tank 401 and the second water storage tank 402. Mounting plates 404 are fixed on both sides of the first water storage tank 401 and the second water storage tank 402. Bolts are fixedly installed between the two mounting plates 404. A water outlet pipe 405 is fixedly installed through one side of the first water storage tank 401. A water pump 406 is fixedly installed on the top of the second water storage tank 402. The other end of the water outlet pipe 405 is fixedly installed on one side of the water pump 406. A water injection pipe 407 is fixedly installed on the top of the second water storage tank 402 to facilitate the injection of dust-suppressing liquid into the first water storage tank 401 and the second water storage tank 402.

[0031] In this embodiment, the bottom of the second water tank 402 is placed on top of the first water tank 401 manually, and the two mounting plates 404 are fixed with bolts. This allows for quick disassembly and assembly of the first water tank 401 and the second water tank 402, facilitating the cleaning of the inner walls of the first water tank 401 and the second water tank 402. This prevents dust and impurities from accumulating on the inner walls of the first water tank 401 and the second water tank 402 and mixing into the water, ensuring the purity of the sprayed water mist. It also avoids clogging of the atomizing nozzle 7 due to water quality issues. Furthermore, when spraying for dust suppression, the water pump 406 is activated, which pumps the dust suppression liquid out through the water outlet pipe 405, enabling continuous spraying for dust suppression at the limestone mining and excavation site.

[0032] The multi-angle adjustment assembly 6 includes a first rotary motor 601 and a drive gear 602. The first rotary motor 601 is fixedly installed on one side of the adjustment frame, and the output shaft of the first rotary motor 601 is rotatably installed inside the other side of the adjustment frame. The drive gear 602 is fixed outside the output shaft of the first rotary motor 601. Mounting shafts are rotatably installed on both sides inside the adjustment frame, and driven half gears 603 are fixed outside the mounting shafts. The drive gear 602 and driven half gears 603 are meshed. A vertical plate 604 is fixed to the top of the driven half gear 603. An arc-shaped groove is provided on the vertical plate 604. A second rotary motor 605 is fixedly installed on one side wall of the vertical plate 604. A connecting plate 606 is fixed to the other end of the output shaft of the second rotary motor 605. A fixing frame 607 is fixed to the top of the connecting plate 606. The fixing frame 607 is located inside the arc-shaped groove. The arc-shaped groove has a limiting effect on the fixing frame 607, allowing the fixing frame 607 to move inside the arc-shaped groove.

[0033] In this embodiment, the first rotating motor 601 drives the driving gear 602 to rotate. The driving gear 602 and the driven half gear 603 are meshed, allowing the driven half gear 603 and the mounting shaft to rotate inside the adjusting frame. This allows for flexible adjustment of the angle of the upright plate 604. Simultaneously, the rotation of the second rotating motor 605 drives the connecting plate 606 to rotate. The connecting plate 606 connects the output shaft of the second rotating motor 605 to the fixed frame 607, enabling the fixed frame 607 to move within the arc-shaped slot. The combined action of the first rotating motor 601 and the second rotating motor 605 allows for multi-angle adjustment of the position of the fixed frame 607, ultimately enabling multi-angle adjustment of the position of the atomizing nozzle 7, thereby increasing the range of dust suppression spray and improving the dust suppression effect.
