Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression devices in mines, specifically to mechanical equipment for dust suppression spraying in mining operations. Background Technology

[0002] Mining operations generate large amounts of dust, which not only poses serious health risks to miners, such as causing respiratory diseases like pneumoconiosis, but also affects operational safety by reducing visibility and increasing the risk of accidents. Therefore, dust control is a crucial aspect of mining operations, especially inside mine tunnels.

[0003] Currently, the most common method for dust suppression in mine roadways is to use spray dust suppression equipment. Traditional spray dust suppression equipment mainly consists of a water supply pipe, a water pump, and an atomizing pipe. Several atomizing nozzles are installed on the atomizing pipe. Water is pumped to the atomizing pipe and then sprayed out through the nozzles to form a water mist to suppress dust.

[0004] However, traditional spray dust suppression equipment has certain drawbacks. Firstly, the width of mine roadways is not entirely uniform, and traditional dust suppression spray equipment lacks the ability to adapt to varying roadway widths. This results in potential dust suppression blind spots in wider or narrower roadways, affecting the dust suppression effect. Secondly, the spraying direction of traditional atomizing pipes is often fixed, typically downwards or to one side, limiting its spray range. This means that some areas in the roadway cannot be effectively treated for dust suppression, thus affecting the overall dust suppression efficiency and quality. Utility Model Content

[0006] The purpose of this utility model is to provide a mining spray dust suppression mechanical device, which aims to solve the problems of poor adaptability of traditional mining spray dust suppression equipment to roadway width adjustment and fixed spraying direction and limited range of atomizing pipes.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a dust suppression spraying machine for mining, comprising two adjustable columns, an atomizing pipe rotatably connected between the upper ends of the two columns, a water supply pipe connected to one end of the atomizing pipe via a rotating joint, a water pump connected to the other end of the water supply pipe, a gear fixedly mounted on the other end of the atomizing pipe, a rack slidably mounted on the upper side of the column corresponding to the gear, the gear meshing with the rack, a drive mechanism for driving the rack to reciprocate linearly on the upper side of the column, and the atomizing pipe being composed of multiple branch pipes detachably spliced ​​together via flanges.

[0009] Furthermore, the bottom of the branch pipe is provided with several atomizing nozzles distributed along its length.

[0010] Furthermore, the column includes a base at the bottom, a telescopic tube fixedly provided on the upper surface of the base, a lifting rod inserted into the upper end of the telescopic tube, an mounting plate fixedly provided on the upper end of the lifting rod, and an atomizing pipe rotatably disposed between the mounting plates.

[0011] Furthermore, the upper end of the telescopic tube is threaded with a fastening bolt, and the side of the lifting rod is provided with several threaded holes, with the fastening bolt and the threaded holes being compatible.

[0012] Furthermore, the driving mechanism includes a rectangular frame fixedly connected to one end of the rack, with rack two fixedly provided on both the upper and lower bottom surfaces inside the rectangular frame, and also includes a motor fixedly provided on the side of the mounting plate.

[0013] Furthermore, two sliding brackets are fixedly provided on the side of the mounting plate, and the two ends of the rack are respectively inserted into the two sliding brackets and slidably connected with the sliding brackets.

[0014] (III) Technical Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. Flexible adaptation to tunnel width: The equipment's column design is height-adjustable, allowing for flexible adjustment of the atomizing pipe height according to the tunnel height. Crucially, the atomizing pipe is composed of multiple branch pipes connected by detachable flanges. The length of the atomizing pipe can be changed by adding or removing branch pipes, enabling it to better adapt to tunnels of different widths and effectively eliminate dust suppression blind spots.

[0017] 2. Increased spraying range: The atomizing pipe is connected at both ends by gears and racks, and the racks are driven by a drive mechanism to reciprocate linearly, allowing the atomizing pipe to swing within a certain angle. The atomizing pipe is composed of multiple branch pipes that are detachably spliced ​​by flanges, and the bottom of each branch pipe is equipped with several atomizing nozzles distributed along its length. Combined with the swinging function of the atomizing pipe, it changes the limitation of the fixed spraying direction of traditional atomizing pipes, which can expand the coverage of water mist and effectively reduce dust suppression blind spots.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Combined with appendix Figure 1 To be continued Figure 7 The dust suppression spraying equipment for mining includes two adjustable columns 1. An atomizing pipe 2 is rotatably connected between the upper ends of the two columns 1. One end of the atomizing pipe 2 is connected to a water supply pipe 3 via a rotating joint 16, and the other end of the water supply pipe 3 is connected to a water pump 4. A gear 5 is fixedly installed at the other end of the atomizing pipe 2. A rack 6 is slidably installed on the upper side of the column 1 corresponding to the gear 5. The gear 5 meshes with the rack 5. A drive mechanism for driving the rack 6 to reciprocate linearly is provided on the upper side of the column 1. The atomizing pipe 2 is composed of multiple branch pipes 7 that are detachably spliced ​​together by flanges 21. Several atomizing nozzles 8 are distributed along the length direction at the bottom of each branch pipe 7.

[0030] In this embodiment, as a preferred technical solution, the column 1 includes a base 9 at the bottom, a telescopic tube 10 fixedly mounted on the upper surface of the base 9, a lifting rod 11 movably connected to the upper end of the telescopic tube 10, a mounting plate 12 fixedly mounted on the upper end of the lifting rod 11, and an atomizing pipe 2 rotatably disposed between the mounting plates 12. A fastening bolt 13 is threadedly connected to the upper side of the telescopic tube 10, and several threaded holes 14 are provided on the side of the lifting rod 11, with the fastening bolt 13 matching the threaded holes 14. Two sliding brackets 20 are fixedly mounted on the side of the mounting plate 12, and the two ends of the rack 6 are respectively inserted into the two sliding brackets 20 and slidably connected to them.

[0031] In this embodiment, as a preferred technical solution, the driving mechanism includes a rectangular frame 15 fixedly connected to one end of the rack 6. The upper and lower bottom surfaces of the rectangular frame 15 are both fixedly provided with rack 2 17. It also includes a motor 18 fixedly provided on the side of the mounting plate 12. The drive shaft of the motor 18 is fixedly provided with an incomplete gear 19. The incomplete gear 19 extends into the rectangular frame 15 and meshes with rack 2 17.

[0032] The working principle of this utility model of a dust suppression spraying device for mining is as follows: The water pump 4 operates, delivering water through the water supply pipe 3 and the rotating joint 16 to the atomizing pipe 2. The atomizing pipe 2 is composed of multiple branch pipes 7 connected together. After the water reaches the branch pipes 7, it is sprayed out from the atomizing nozzles 8 at the bottom to form a water mist. One end of the atomizing pipe 2 is connected to the water supply pipe 3 via the rotating joint 16, ensuring smooth rotation. At the other end of the atomizing pipe 2, the gear 5 meshes with the rack 6. The motor 18 on the side of the mounting plate 12 drives the incomplete gear 19 to rotate. The incomplete gear 19 intermittently meshes with the rack 17 inside the rectangular frame 15. Since the rectangular frame 15 is fixedly connected to the rack 6, the rack 6 is driven to reciprocate linearly within the sliding bracket 20. The rack 6 drives the gear 5 to rotate, thereby causing the atomizing pipe 2 to oscillate at a certain angle around the rotation point between the upper ends of the two columns 1. The lifting and lowering adjustment of column 1 is achieved through telescopic tube 10 and lifting rod 11. Loosening the fastening bolt 13 adjusts the height of lifting rod 11 within telescopic tube 10. After proper adjustment, tightening the fastening bolt 13 fixes the lifting rod 11, thereby changing the height of atomizing pipe 2. In addition, the length of atomizing pipe 2 can be adjusted by disassembling or adding branch pipes 7 through flange 21 according to the width of the tunnel.

[0033] The working process of this utility model of a dust suppression spraying device for mining is as follows:

[0034] 1. Equipment Installation: Place the two columns 1 at suitable positions on both sides of the tunnel. The base 9 of each column 1 is bolted to the tunnel floor. Connect the water pump 4 to the water source, and connect one end of the water supply pipe 3 to the water pump 4, and the other end to the atomizing pipe 2 via the swivel joint 16. Adjust the height of the columns 1 initially according to the approximate height of the tunnel. Specifically, loosen the fastening bolts 13, adjust the position of the lifting rod 11 within the telescopic pipe 10, and tighten the fastening bolts 13 after the mounting plate 12 reaches the appropriate height. Install an appropriate number of branch pipes 7 according to the approximate width of the tunnel, splice them together with flanges 21 to form the atomizing pipe 2, and place it between the mounting plates 12 at the top of the two columns 1.

[0035] 2. Dust Suppression Operation: Start water pump 4 and motor 18. Water pump 4 delivers water to atomizing pipe 2. The water mist sprayed from atomizing nozzles 8 suppresses dust in the tunnel. Simultaneously, atomizing pipe 2 oscillates under the drive of motor 18 and other mechanisms, allowing the water mist to cover a wider area, achieving efficient dust suppression. During operation, regularly check the equipment's operating status, including the operating status of water pump 4 and motor 18, as well as the spraying effect of atomizing nozzles 8. If any problems are found, stop the machine immediately for maintenance.
