Detailed implementation mode

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

It is characterized in that: a water spraying and atomizing device 11 for water spraying and atomizing is installed on the housing mounting component 12, and the water spraying and atomizing device 11 is movably connected to the housing mounting component 12, providing convenience for the installation and disassembly of the water spraying and atomizing device 11;

[0043] The water spraying and atomizing device 11 includes a device housing 19, an external connecting water pipe 20 is installed at the top of the device housing 19, and the external connecting water pipe 20 is externally connected to a water source;

[0044] A movable fixed rod 21 is movably installed on the side of the water spraying and atomizing device 11. One end of the movable fixed rod 21 is fixedly installed with a control knob 22. By pulling and rotating the control knob 22, the movable fixed rod 21 is driven to move and rotate on the device housing 19;

[0045] An internal water guiding pipe 25 is installed on the movable fixed rod 21, a water spraying component 26 and an atomizing component 27 are installed on the internal water guiding pipe 25, a limiting sleeve 23 is sleeved outside the internal water guiding pipe 25, and the external connecting water pipe 20 is connected to the internal water guiding pipe 25 through a pipeline. The external connecting water pipe 20 provides water source for the internal water guiding pipe 25.

[0046] The housing mounting part 12 and the water spraying and atomizing device 11 adopt a movable connection structure. By operating the control knob 22 to pull or rotate the movable fixing rod 21, the water spraying part 26 and the atomizing part 27 on the internal water guiding pipe 25 are driven to move, so that their nozzles are aligned with the cutting area. The external water source flows into the internal water guiding pipe 25 through the external connecting pipe 20 and finally sprays out through the nozzles to realize the water spraying or atomizing function;

[0047] The movable connection design avoids the traditional fixed welding or bolt fastening methods, can quickly disassemble and assemble the water spraying and atomizing device, greatly shortens the maintenance time, and is convenient for replacing vulnerable parts such as nozzles and water pipes;

[0048] It has both water spraying and atomizing functions at the same time. By adjusting the position of the nozzle through the movable fixing rod, it can meet the dust reduction requirements of different cutting scenarios. For example, high-pressure water spraying at close range can wash large particle dust, and atomizing spray at long range can adsorb fine dust.

[0049] Embodiment 2, on the basis of Embodiment 1, please refer to Figure 5-6

[0050] Two groups of the water spraying part 26 and the atomizing part 27 are provided.

[0051] Two limiting grooves 24 are formed on the limiting sleeve 23. When the control knob 22 drives the movable fixing rod 21 to move, the nozzles in each group of the water spraying part 26 and the atomizing part 27 are clamped in the two limiting grooves 24, so that the water spraying part 26 and the atomizing part 27 spray water or atomize to the outside;

[0052] When the control knob 22 drives the movable fixing rod 21 to move, the nozzle will be clamped in the limiting groove to fix the spraying angle, realizing the switching and direction adjustment of the water spraying or atomizing function;

[0053] The nozzles distributed in a circle can adjust the spraying direction by 360°, comprehensively covering the dust generation area in the circumferential direction of the cutting gear, and solving the blind area problem of traditional single-sided spraying; the water spraying and atomizing parts are arranged alternately, which can handle dust of different particle sizes at the same time and improve the overall dust reduction efficiency;

[0054] The limiting groove clamps the nozzle, effectively resisting the deviation of the nozzle caused by the vibration of the equipment, ensuring that the spraying direction is always accurately aligned with the dust source, and avoiding affecting the dust reduction effect due to position change;

[0055] When the water spraying part 26 and the atomizing part 27 move, the positions of the water spraying part 26 and the atomizing part 27 will change, so that the positions of water spraying and atomizing change, achieving various effects of water spraying and atomizing methods.

[0056] Example 3. On the basis of Example 2, please refer to Figure 1-3

[0057] A protective baffle 13 is fixedly installed on the housing mounting part 12. An installation card slot 14 is provided at the middle position of the protective baffle 13. An installation component 15 is movably installed in the installation card slot 14. The water spraying and atomizing device 11 is installed on the housing mounting part 12 through the installation component 15;

[0058] The installation component 15 is rotationally engaged in the card slot through an installation card plate 16. Rotate the installation card plate to lock or unlock it with the card slot, so as to fix or disassemble the water spraying and atomizing device 11 on the housing mounting part;

[0059] The device can be fixed by rotating the installation card plate without tools. Compared with the traditional bolt connection, the installation time is greatly shortened, and the equipment assembly efficiency is improved; the operation is simple during disassembly, which is convenient for quick maintenance;

[0060] The protective baffle not only provides protection for the cutting machine, but also serves as the installation carrier of the water spraying and atomizing device, simplifies the overall structure of the equipment, reduces the number of parts and the installation complexity.

[0061] Example 4. On the basis of Example 3, please refer to Figure 3-4

[0062] The installation component 15 includes an installation card plate 16. The installation card plate 16 is rotationally engaged in the installation card slot 14. The installation card plate 16 is designed as a rectangle. Rotate the installation card plate 16 to engage the installation card plate 16 in the installation card slot 14 or disassemble it from the installation card slot 14;

[0063] A connecting threaded pipe 17 is fixedly installed on the installation card plate 16. A fixing threaded post 18 is threadedly connected to the connecting threaded pipe 17. The fixing threaded post 18 is fixedly connected to the device housing 19;

[0064] After the installation card plate 16 is rotationally engaged in the installation card slot 14, through the threaded connection between the connecting threaded pipe 17 and the fixing threaded post 18, the device housing 19 is fastened to the mounting part. When disassembling, reverse-rotate the fixing threaded post to separate the device, realizing quick disassembly and assembly;

[0065] The threaded connection provides high-strength fixation, can withstand the high-frequency vibration of the cutting equipment, and avoids the device from falling off; the installation position of the device can be finely adjusted by adjusting the threaded insertion depth to ensure that the nozzle is aligned with the best dust reduction point, improving the dust reduction accuracy;

[0066] The threaded interface design can be adapted to the cutting equipment housings of different sizes without customized modification, reducing the equipment adaptation cost and expanding the application range of the device.

[0067] Example 5. On the basis of Example 4, please refer to Figure 5-7

[0068] The inner water guiding water pipe 25 has three layers. The outer layer is the outer water guiding pipe 32, which is used to clamp the nozzle. A nozzle connecting pipe 28 is fixedly installed on the nozzle, and the nozzle connecting pipe 28 is clamped on the outer water guiding pipe 32;

[0069] The middle layer is the middle layer sealing pipe 33, which is used to seal the nozzle. Water remains between the outer water guiding pipe 32 and the middle layer sealing pipe 33, and the inner layer is the inner fixed pipe body 34;

[0070] The inner water guiding water pipe 25 adopts a three-layer structure: the outer water guiding pipe 32 is used to clamp the nozzle connecting pipe 28 to provide a nozzle installation interface; the middle layer sealing pipe 33 wraps the inner pipe body to form a sealed cavity to prevent water leakage; the inner fixed pipe body 34 supports the overall structure to ensure that the water pipe remains rigid and does not deform during movement and adjustment;

[0071] The middle layer sealing pipe isolates the water flow from the external environment. Combined with the clamping design of the outer water guiding pipe, it effectively solves the water leakage problem caused by vibration or wear of the traditional single-layer water pipe, and improves the sealing performance and reliability of the water path system;

[0072] The inner fixed pipe body bears the tensile force and torsional force of the movable fixing rod, avoids the water pipe from cracking or deforming during frequent adjustment, prolongs the service life of the device, and adapts to long-term high-frequency use scenarios.

[0073] Example 6. On the basis of Example 5, please refer to Figure 7

[0074] A sealing part 29 is fixedly installed on the outside of the middle layer sealing pipe 33, and the sealing part 29 is adapted to the bottom of the nozzle connecting pipe 28. When the nozzle connecting pipe 28 moves downward, the sealing part 29 fits with the nozzle connecting pipe 28 to seal the nozzle connecting pipe 28;

[0075] The bottom of the nozzle connecting pipe 28 is adapted to the sealing part 29. When the nozzle moves to the working position along with the movable fixing rod 21, the nozzle connecting pipe moves downward, and the sealing part fits with the bottom of the connecting pipe to block the water leakage path; when the nozzle resets, the sealing part separates from the connecting pipe to allow water to pass through the corresponding nozzle;

[0076] Dynamic sealing during the movement of the nozzle is achieved through a mechanical structure. The precise adaptation of the sealing part and the connecting pipe significantly improves the wear resistance compared with the traditional static sealing ring, is suitable for high-frequency adjustment scenarios, and reduces the sealing part replacement frequency;

[0077] Ensure that when switching between the water spraying and atomizing functions, the water flow only sprays out from the currently working nozzle, avoiding water resource waste and reduced dust suppression effect caused by simultaneous leakage of multiple nozzles, and improving the reliability of function switching.

[0078] Embodiment Seven, based on Embodiment Six, please refer to Figure 7

[0079] At the bottom of the nozzle connecting pipe 28, a connecting support rod 35 is fixedly installed through a bracket. An activity perforation 30 is provided at the middle position of the sealing part 29. The connecting support rod 35 passes through the activity perforation 30. A return spring 36 is fixedly installed on the connecting support rod 35. The return spring 36 is fixedly connected to the inner layer fixed pipe body 34. The return spring 36 provides elastic force for the nozzle connecting pipe 28 and the nozzle.

[0080] The connecting support rod 35 passes through the activity perforation 30 of the sealing part 29, with one end fixed to the bottom of the nozzle connecting pipe 28 and the other end connected to the inner layer fixed pipe body 34 through the return spring 36. When adjusting the nozzle, the spring compresses to store elastic force. After loosening the knob, the spring releases the elastic force to push the nozzle to automatically reset to the initial limit groove 24, maintaining the preset spraying position.

[0081] The return spring provides an automatic return function, eliminating the need for manual adjustment. After the equipment stops or vibrates, the nozzle can automatically return to the initial position, reducing operation errors and calibration time, and improving the convenience of use.

[0082] The elastic force of the spring offsets the impact force of the equipment vibration on the nozzle, avoiding the problem of nozzle displacement due to vibration in traditional rigid connections, ensuring the stability of the spraying direction during long-term use, and maintaining a continuous and effective dust suppression effect.

[0083] Embodiment Eight, based on Embodiment Seven, please refer to Figure 7

[0084] An elastic sealing gasket 31 is installed on the inner wall of the outer layer water guide pipe 32. The elastic sealing gasket 31 is made of an elastic material. After the nozzle connecting pipe 28 and the nozzle move between the outer layer water guide pipe 32 and the middle layer sealing pipe 33, the nozzle comes into contact with the elastic sealing gasket 31, and the nozzle is sealed through the elastic sealing gasket 31.

[0085] An elastic sealing gasket 31 (such as rubber material) is installed on the inner wall of the outer layer water guide pipe 32. When the nozzle connecting pipe 28 moves to the working position, the end face of the nozzle is in close contact with the elastic sealing gasket. The elastic deformation of the gasket is used to fill the tiny gaps. The greater the water flow pressure, the tighter the sealing gasket fits, forming an adaptive sealing effect.

[0086] The middle - layer sealing pipe is combined with an elastic sealing gasket, forming a dual leak - prevention system of structural sealing and elastic sealing. Even in a high - pressure water flow environment, it can effectively prevent leakage and improve the sealing reliability of the water circuit system.
