The air cavity 602 is provided with a dust suction groove 603 at the bottom of the side of the saw blade 7, and the dust suction groove 603 is located below the drive shaft. The air cavity 602 is provided with a plurality of dust suction holes 604 on the side of the saw blade 7, and the dust suction holes 604 are distributed above the drive shaft. In the process of the saw blade 7 rotating to saw the brick and stone, the dust suction groove 603 and the dust suction holes 604 located on both sides of the saw blade 7 and opening towards the saw blade 7 directly vacuum the surface of the saw blade 7, so that the dust generated during sawing can be directly sucked out from the dust suction groove 603 and the dust suction hole 604 to avoid being contaminated on the surface of the saw blade 7, causing thickness changes and affecting the flatness of subsequent sawing.

[0035] In the present invention, a cavity 101 is provided inside the saw table 1. A water tank 21 is installed at a position on the inner wall of the cavity 101 corresponding to the saw slot 102. The water tank 21 extends horizontally in the extending direction of the saw slot 102. One end of the water tank 21 is communicated with a water injection pipe 20. A plurality of spray nozzles 22 facing the saw slot 102 are arranged above the water tank 21. A connecting hose 23 is communicated between the spray nozzle 22 and the top of the water tank 21. The plurality of spray nozzles 22 are equidistantly distributed in the extending direction of the water tank 21. Roller shafts 24 are horizontally rotatably arranged at the four corners of the water tank 21. A rotating belt 25 is rotatably connected between the four roller shafts 24. It should be noted that in order to maintain the stability of the rotational connection between the roller shaft 24 and the rotating belt 25, engaged tooth blocks and tooth grooves are arranged at the appropriate positions between the roller shaft 24 and the rotating belt 25; the outer wall of the rotating belt 25 is in close sliding contact with the inner wall of the water tank 21. It should be noted that the top outer wall of the rotating belt 25 is in sliding contact with the top inner wall of the water tank 21, the bottom outer wall of the rotating belt 25 is in sliding contact with the bottom inner wall of the water tank 21, and the two outer walls of the rotating belt 25 are respectively in sliding contact with the two inner walls of the water tank 21. The opening at the end surface of the rotating belt 25 facing the water tank 21 is communicated with the water injection pipe 20; a through slot 251 is formed at the top of the rotating belt 25. The through slot 251 corresponds to the distribution direction of the plurality of spray nozzles 22. The through slot 251 is located directly below the saw blade 7. The rotating belt 25 moves as the saw blade 7 moves horizontally, so that the through slot 251 always remains below the saw blade 7. By injecting water into the water tank 21 through the water injection pipe 20, the other positions of the rotating belt 25 away from the through slot 251 will block the bottom ends of the corresponding connecting hoses 23, while the bottom ends of the connecting hoses 23 at the positions corresponding to the through slot 251 are communicated with the inside of the water tank 21, so that the corresponding spray nozzles 22 flush upward towards the surface of the saw blade 7 for cleaning. The dust suction groove 603 and the dust suction holes 604 can simultaneously suck away the water mist under negative pressure to improve the dust removal and cleaning effect on the surface of the saw blade 7 to ensure the sawing flatness.

[0036] In the present invention, a cross bar 29 is installed on the outer wall of the mounting frame 6. The cross bar 29 is located on one side of the nozzle 22. A guiding groove 211 is formed at the position corresponding to the cross bar 29 on the top of the water tank 21. The guiding groove 211 is arranged parallel to the sawing groove 102 and is located on one side of the nozzle 22. A fixing block 30 is installed between the bottom of the cross bar 29 and the rotating belt 25. The outer wall of the fixing block 30 is in sliding contact with the inner wall of the guiding groove 211. Both sides of the sawing groove 102 are open. A connecting frame 26 is installed on the outer wall of the mounting frame 6. One end of the connecting frame 26 away from the mounting frame 6 is fixed with a vertical rod 27. A vertical sleeve 28 is slidably connected to the outside of the vertical rod 27. A spring is connected between the vertical rod 27 and the vertical sleeve 28. The bottom end of the vertical sleeve 28 is fixed to the cross bar 29. A limiting sleeve 31 is fixed above the water tank 21 on the outer wall of the fixing block 30. The bottom of the limiting sleeve 31 is in sliding contact with the top outer wall of the water tank 21, and the outer diameter of the limiting sleeve 31 is greater than the width of the guiding groove 211. Through the telescopic arrangement of the vertical rod 27 and the vertical sleeve 28, the stability of the cross bar 29 can be ensured during the lifting and lowering of the mounting frame 6, so that the rotating belt 25 and the through groove 251 above it always move horizontally along with the saw blade 7, thereby ensuring that the nozzle 22 below the moving position of the saw blade 7 is connected to the water tank 21 to flush the saw blade 7 with water.

[0037] In the present invention, two support frames 14 are installed at one end of the inner wall of the bottom of the cavity 101. A rotating shaft 15 is rotatably connected between the two support frames 14. The rotating shaft 15 is arranged parallel to the sawing groove 102. A plurality of limiting plates 16 are installed on the outer wall of the rotating shaft 15. One end of the rotating shaft 15 is drivingly connected to a second motor 17. A notch 103 is formed at the position corresponding to the limiting plate 16 at the end of the saw table 1. The notch 103 is located on the side of the sawing groove 102. By driving the rotating shaft 15 and the limiting plates 16 to rotate through the second motor 17, the limiting plates 16 are tilted to limit the end of the saw table 1. The staff operates at the other end of the saw table 1 and pushes the masonry against the surface of the limiting plate 16 to completely align the position. And through the notch 103 close to the sawing groove 102, the rotating limiting plate 16 can limit the masonry; A first suction cup 18 is installed at the position between adjacent notches 103 on the top of the saw table 1. A plurality of second suction cups 19 are installed at the position of the end of the saw table 1 away from the notch 103 and close to the sawing groove 102. It should be noted that: the tops of the first suction cup 18 and the second suction cups 19 are flush with the top surface of the saw table 1. The second suction cups 19 are arranged in a strip-shaped structure and the second suction cups 19 are in the same extending direction as the sawing groove 102. A plurality of negative pressure suction ports are arranged on the second suction cups 19; When in use, after the masonry is limited and placed by the deflected limiting plate 16, the first suction cup 18 and the second suction cups 19 are used to adsorb and fix the masonry. Compared with the clamping operation, it can effectively avoid applying force towards the cutting groove position during sawing, resulting in accidental deformation and affecting the flatness of sawing.

[0038] In the present invention, baffles 10 are provided on both sides of the mounting frame 6. Slots are formed at positions corresponding to the saw blade 7 on the baffles 10, and friction pads 11 made of silica gel material are fixed in the slots. Grooves 111 are formed at positions corresponding to the saw blade 7 on the friction pads 11, and the inner walls of the grooves 111 are in contact with the outer wall of the saw blade 7. The baffles 10 extending from both sides of the mounting frame 6 can assist in blocking sawing debris and spraying water, avoiding excessive dust and water splashing, and enabling friction between the surface of the saw blade 7 and the friction pads 11 during the rotation of the saw blade 7. Combining with dust suction and flushing operations can improve the cleaning effect on the surface of the saw blade 7, thereby ensuring the flatness and effectiveness of sawing.

[0039] In the present invention, positioning holes are formed at positions near the mounting frame 6 at both ends of the baffle 10. A positioning shaft 13 is rotatably connected to the inner wall of the positioning hole through a torsion spring. A positioning block 12 is fixed to the end of the positioning shaft 13 away from the baffle 10, and the positioning block 12 is fixed to the mounting frame 6. In the normal state, the baffle 10 tends to be in a horizontal placement state through the torsion spring. During the process of water flow change flushing below the saw slot 102, the baffles 10 on both sides of the mounting frame 6 swing, so as to achieve the movement change effect of the contact between the friction pads 11 and the saw blade 7. Thus, by cooperating with the movement changes of dust suction, flushing water, and the frictional movement change of the friction pads 11, the cleaning effect on the saw blade 7 is improved.

[0040] In the present invention, a horizontally placed shaft block 221 is fixed at one end position on the outer wall of the nozzle 22. The axis of the shaft block 221 is perpendicular to the extension direction of the saw slot 102. A positioning frame 32 is rotatably connected to the outer wall of the shaft block 221, and the positioning frame 32 is fixed to the top of the water tank 21. The nozzle 22 can rotate around the shaft block 221, so as to continuously change the flushing angle of the surface of the saw blade 7 through the nozzle 22 deflected below the saw blade 7, thereby improving the dust removal and cleaning effect on the surface of the saw blade 7.

[0041] Regarding the technical setting that the nozzle 22 can rotate around the shaft block 221, different embodiments can be selected according to the actual situation to complete the operation:

[0042] Embodiment 2: Refer to Figures 1-8 and Figures 13-14 , a dust removal and cleaning device for stone processing. On the basis of Embodiment 1, the shaft block 221 and the positioning frame 32 are rotatably connected through a torsion spring. Since the bottom end of the nozzle 22 is communicated with the water tank 21 through a connecting hose 23, when the through slot 251 is connected to the corresponding connecting hose 23 to make the connecting hose 23 and the nozzle 22 flush with water, under the action of hydraulic impact, the nozzle 22 can swing and deflect to perform variable-direction flushing on the surface of the saw blade 7. Compared with Embodiment 3 and Embodiment 4, the swing of the nozzle 22 is more free, but relatively speaking, it cannot be controlled. This embodiment is suitable for use in situations where the requirement for sawing flatness is lower.

[0043] Embodiment 3: Refer toFigures 1-6 and Figures 9-10 as well as Figures 13-14 , a dust removal and cleaning device for stone processing, based on Example 1, the shaft block 221 is rotatably connected to the positioning frame 32 through a bearing, and the end of the shaft block 221 away from the nozzle 22 is transmission-connected to the motor three 33, and the motor three 33 that moves the saw blade 7 to the corresponding position through program control actively controls the reciprocating deflection operation of the nozzle 22. Compared with Examples 2 and 4, this embodiment can more stably and accurately control the deflection and flushing operation of the nozzle 22, effectively avoiding the uncontrollability of free swinging, but it also needs to set up more electrical appliances, sensors and controllers to control the use of motor three 33. This embodiment is more suitable for the needs of high precision in sawing flatness and without considering the cost of equipment.

[0044] Example 4: Reference Figures 1-6 and Figures 11-14 The end of the cross bar 29 away from the vertical sleeve 28 is located directly below the drive shaft, and the end of the cross bar 29 away from the vertical sleeve 28 is provided with a magnetic block 34. When there is no external force, the nozzle 22 remains in a vertical upward state under the action of the torsion spring. During the sawing process, the magnetic block 34 is located directly below the saw blade 7, and the nozzles 22 near the magnetic block 34 will also spray water because their bottom ends are connected to the through groove 251. At this time, the nearby nozzles 22 will be deflected toward the middle position of the saw blade 7 under the action of the magnetic attraction, and as the magnetic block 34 and the saw blade 7 move, the deflection angle of the nozzle 22 will continue to change, thereby continuously changing the flushing effect on the surface of the saw blade 7.

[0045] Compared with Example 2, this design can more stably control the deflection operation of the nozzle 22, and compared with Example 3, it can effectively reduce the use of electrical appliances, and can make the deflection of the nozzle 22 active and variable rather than fixed path deflection; therefore, compared with Examples 2 and 3, the solution of this embodiment is more cost-effective.

[0046] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
