[0022] In the embodiment applying the above technical scheme, the existing stone cutting is to place the large block of stone produced to the cutting table, the cutting device 4 is driven by the moving frame 2 to move, so as to complete the cutting of the stone, before cutting, the cutting device 4 is moved to one side of the stone, the water spraying assembly 7 will first contact the stone, so as to extrude and move up, so that the cutting blade 41 in the middle is exposed, the stone is cut through the exposed cutting blade 41, two water spraying assemblies 7 are arranged on both sides of the cutting blade 41, and the water spraying range is limited in the limiting space, when cutting, the water tank 71 sends water to the inside of the side spray head 72 and the top plate 74, through the side edge spraying of the side spray head 72 and the upper spraying of the top plate 74, a better dust falling effect can be achieved, at the same time, the water slurry generated is limited in the limiting space, the range of water slurry splashing is reduced, and subsequent cleaning is facilitated.

[0023] The present application falls dust from multiple angles, limits the water slurry generated by wet cutting, avoids the splashing of water slurry everywhere, and facilitates subsequent cleaning.

[0024] The preferred technical scheme in the embodiment is: Referring to Figures 2-3 , the cutting frame 3 further comprises a sliding frame 32, the sliding frame 32 is slidingly arranged on the moving frame 2, and the bottom plate 31 is rotatably installed at the bottom of the sliding frame 32; The connecting frame 5 further comprises two bases 52 and two side frames 53, the two bases 52 are fixedly installed below the bottom plate 31, and the two side frames 53 are symmetrically fixedly installed at the side edges of the clamping frame 51. The side frame 53 is connected with the base 52 through bolts.

[0025] Since it is necessary to cut the large stone into stone with the same width, the sliding of the sliding frame 32 on the moving frame 2 is controlled to drive the horizontal movement of the entire cutting device 4, thereby facilitating the adjustment of the width of the cutting stone.

[0026] In order to firmly install the position of the water spraying assembly 7, the two bases 52 for connection are arranged below the bottom plate 31, the side frames 53 are arranged at the side edges of the clamping frame 51, and the side frame 53 is connected with the base 52 through bolts, so that the position of the water spraying assembly 7 is adjusted and fixed, the cutting blade 41 is limited in the middle of the water spraying assembly 7, the contact between the blade and the water spraying assembly 7 during cutting is avoided, the water spraying assembly 7 can be quickly installed and disassembled through the connecting frame 5, and the horizontal position of the water spraying assembly 7 can be adjusted, so that the normal cutting is ensured.

[0027] Referring to Figures 3-4 , the cutting device 4 further comprises a driving motor 42, a driving shaft 43, a mounting frame 44 and a linkage tooth belt 45. The driving motor 42 is fixedly installed on the upper surface of the sliding frame 32. The mounting seat is fixedly installed on the bottom plate 31. The driving shaft 43 is rotatably installed on the mounting seat, and the cutting blade 41 is fixedly connected to the output end of the driving shaft 43. The linkage tooth belt 45 is sleeved on the output end of the driving motor 42 and the driving end of the driving shaft 43.

[0028] During cutting, the cutting blade 41 will be subjected to a large resistance during cutting, thereby causing the shaft connected with the cutting blade 41 to be subjected to extrusion for a long time, which is easy to cause deformation. If the cutting blade 41 is directly fixed to the output end of the motor, the output end of the motor is also easy to be subjected to stress deformation, which affects the long-term use of the motor.

[0029] The output end of the driving motor 42 and the driving end of the driving shaft 43 are linked through the linkage tooth belt 45. The gear on the motor output end and the gear on the end of the driving shaft 43 are clamped in the clamping groove of the linkage tooth belt 45, which ensures the rotation of the driving shaft 43 and the rotation of the cutting blade 41 after being subjected to stress. The linkage tooth belt 45 will not be separated from the driving shaft 43 and the motor, thereby ensuring the rotation driving of the cutting blade 41.

[0030] The driving shaft 43 is fixed by the mounting frame 44, so that the impact force is effectively reduced, and the service life of the driving shaft 43 is prolonged.

[0031] With reference to Figures 5-7 The sound insulation assembly 6 further comprises a folding plate 62 fixedly connected between the side plate 61 and the clamping frame 51, wherein the folding plate 62 is made of elastic material and is arranged in a wave shape.

[0032] The cutting blade 41 is in hard contact with the stone during cutting, so that a large noise is generated, the processing environment is polluted by noise, and the cutting personnel are physically injured after working in such an environment for a long time.

[0033] The folding plate 62 and the side plate 61 on both sides form a sound insulation space on both sides of the cutting blade 41, so that the generated noise is limited in the sound insulation space, the diffusion of the noise is reduced, and the noise is reduced and the pollution of the noise is reduced due to the wave shape of the folding plate 62.

[0034] The folding plate 62 is made of elastic material, the folding plate 62 drives the side plate 61 to move downward when the cutting process is not performed, so that the water spraying assembly 7 is located at the lower end of the cutting blade 41, the side plate 61 is driven to move upward when the water spraying assembly 7 is in contact with the stone during cutting, so that the folding plate 62 is pressed, and the water spraying assembly 7 is reset by the elastic folding plate 62 after the cutting is completed.

[0035] With reference to Figure 6 The middle part of the water tank 71 is a water storage area recessed inward, and rotating grooves are formed in the bottoms of both ends, the rotating grooves are rotatably installed with rolling wheels 9, and the recessed sides of the water tank 71 are fixedly connected with sealing sheets 10.

[0036] Due to the rough surface of part of the stone, in order to avoid blocking the lower part of the water tank 71 and ensure the normal movement of the water spraying assembly 7 on the surface of the stone, two rolling wheels 9 are arranged at both ends of the water tank 71, so that there is enough gap between the bottom surface of the water tank 71 and the surface of the stone, the bottom surface of the water tank 71 is prevented from colliding with the surface of the stone during the cutting process, the gap is blocked by the sealing sheets 10, the mud generated during the wet cutting process is limited in the limiting space, and the mud is cleaned.

[0037] Meanwhile, the sealing sheets 10 can scrape and clean the water slurry limited in the limiting space, the water slurry moves with the limiting space, the water slurry is transferred after the cutting is completed, and the water slurry is prevented from accumulating on the surface of the stone.

[0038] With reference to Figure 8 , the side nozzle 72 is arranged on one side of the side plate 61 close to the feeding end, a poking assembly 8 is arranged between the rolling wheel 9 and the side nozzle 72, the poking assembly 8 comprises a plurality of poking rods 81 and a moving rod 82, a strip-shaped opening in communication with the water placing area is formed on the side of the rotating groove, the plurality of poking rods 81 are fixedly connected in a ring shape on the side of the rolling wheel 9 close to the feeding end, the moving rod 82 is fixedly connected on one side of the side nozzle 72 and located inside the strip-shaped opening, and the poking rod 81 drives the moving rod 82 to deflect during rotation.

[0039] When the dust generated in the cutting process is treated by water spraying, due to the large impact force generated during cutting, the dust will be scattered to the entire limiting space, and due to the mutual blocking of the dust, the unidirectional spraying of the atomizing nozzle can only spray and reduce dust for part of the dust, and part of the dust is still not sprayed, which reduces the dust reduction effect.

[0040] Since the rolling wheel 9 moves on the surface of the stone along with the movement of the moving frame 2, the poking rod 81 fixedly connected on the side of the rolling wheel 9 rotates during movement of the rolling wheel 9, the moving rod 82 is pressed and deflected downward during rotation of the plurality of rotating poking rods 81, so that the side nozzle 72 is deflected upward, the spraying area of the side nozzle 72 is increased, the side nozzle 72 is an atomizing nozzle, the contact between the sprayed water and the dust is increased, and a better dust reduction effect is achieved.

[0041] With reference to Figure 9 , limit grooves are symmetrically formed inside the sliding opening, the sliding block 13 is limitingly and slidably arranged inside the limit groove, a through opening in communication with the top plate 74 and the telescopic pipe 73 is formed in the sliding block 13, and the sliding block 13 and the top plate 74 are used for pressing the telescopic pipe 73; The telescopic pipe 73 comprises two support ends 731, a telescopic section 732 and a connecting section 733, one of the support ends 731 is fixedly connected to the bottom end of the sliding block 13, and the other support end 731 is fixedly connected to the bottom end of the sliding opening, the telescopic section 732 is arranged between the two support ends 731, and the connecting section 733 is fixedly connected between the water tank 71 and the lower support end 731.

[0042] By arranging the top plate 74 which can slide up and down inside the side plate 61, when the stone is cut, the water tank 71 will supply water to the inside of the telescopic pipe 73, a large amount of water will accumulate in the telescopic pipe 73 due to the small diameter of the nozzle above the top plate 74, so that the telescopic pipe 73 is expanded and extended, the top plate 74 is pushed to the upper side of the sliding opening, and the upper side of the limiting space is blocked by the two side top plates 74, so that the noise reduction is enhanced and the flying of the dust is reduced.

[0043] At the same time, the top plate 74 above will also spray water from the upper nozzle, so that the upper part of the limiting space forms a spray layer, thereby ensuring the dust-settling effect on dust.

[0044] When the cutting is completed, the water tank 71 no longer supplies water to the inside of the telescopic pipe 73, and due to the gravity of the sliding block 13 and the top plate 74, the telescopic pipe 73 is squeezed, so that the water in the inside of the telescopic pipe 73 is squeezed out, and the top plate 74 is moved downward to reset.

[0045] With reference to Figure 9 The top plate 74 is provided with a downwardly inclined scraping strip 11 on the side close to the side plate 61, and is provided with a cleaning strip 12 on the side close to the cutting blade 41, which is used to clean the side edge of the cutting blade 41 when moving downward.

[0046] After the cutting is completed, part of the water slurry adheres to the surface of the cutting blade 41 and the side plate 61, and after a long time without cleaning, the water slurry solidifies, which affects the overall heat dissipation effect of the cutting blade 41, and also makes it inconvenient to clean the side plate 61 later.

[0047] Before the cutting work, the top plate 74 is located below the side plate 61, and the cleaning strip 12 is in contact with the cutting blade 41, and after the cutting work starts, due to the extension of the telescopic pipe 73, the sliding block 13 moves upward along the side plate 61, and due to the inclined arrangement of the inner side of the side edge, the distance between the two top plates 74 increases, so that the cleaning strip 12 is separated from the cutting blade 41, avoiding the friction between the cutting blade 41 and the cleaning strip 12 during cutting, and after the cutting is completed, the top plate 74 moves downward, and due to the inclined arrangement of the inside of the side plate 61, the distance between the two top plates 74 decreases during the downward movement of the top plate 74, so that the cleaning strip 12 comes into contact with the side edge of the cutting blade 41, thereby scraping and cleaning the side edge of the cutting blade 41, and the downwardly moving scraping strip 11 can scrape the surface of the side plate 61 to clean the adhered water slurry.

[0048] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
