DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1: Figure 1-3As shown, a pavement seam cutting machine according to an embodiment of the present invention comprises a support frame 1, wherein first fixed blocks 12 are fixedly connected to both sides of the support frame 1, and first rectangular bars 121 are fixedly connected to one side of the first fixed blocks 12, and second rectangular bars 122 are slidably connected to one end of the first rectangular bars 121, and a rotating shaft 14 is rotatably connected between the second rectangular bars 122, and an arc cover 13 is fixedly connected to one side of one of the second rectangular bars 122, and a blade 15 is rotatably connected to the middle of the arc cover 13, The end of the rotating shaft 14 passes through the arc cover 13 and is fixedly connected to the middle of the blade 15. A dust collection assembly is provided on one side of the lower end of the support frame 1. The dust collection assembly includes an arc box 2 fixedly connected to one side of the lower end of the support frame 1. The arc box 2 is located on one side of the blade 15. A second cylinder 24 is fixedly connected to one side of the arc box 2, and a third cylinder 25 is fixedly connected to the middle of the second cylinder 24. A dust bag 26 is fixedly connected to one end of the second cylinder 24 away from the arc box 2, and the third cylinder 25 is fixedly connected to the support frame 1 through a second fixing block 27.

[0032] Specifically, when cracks and depressions appear on the road surface, they need to be repaired in time to prevent the uneven road surface from causing bumps when vehicles pass by and causing traffic accidents. When repairing, first cut a circle around the outside of the damaged part of the ground, then hollow out the middle of the cut, and then pour new concrete to complete the repair; when cutting the ground, there is a lot of dust when cutting concrete, which will pollute urban roads and the surrounding environment. After the cutting is completed, the existing seam cutting machine cleans the ground, but the fine dust flying in the air cannot be removed, which will pollute the surrounding environment and passers-by on urban roads; when using the present invention, the driving support frame 1 drives the blade 15 to be located on one side of the damaged part of the road surface, and then drives the rotating shaft 14 to rotate to drive the blade 15 to rotate, and at the same time drives the second rectangular bar 122 to drive the arc cover 13 to slide to the lower end, so that the blade 15 contacts and extends into the ground The surface is cut, and the rotation direction of the blade 15 is opposite to the forward direction of the support frame 1, so that the dust and impurities generated during the cutting enter the arc box 2, and an air pump can be installed at one end of the third cylinder 25, and the air pump is started to extract the air inside the third cylinder 25 and the second cylinder 24 outward, and at the same time, the dust in the second cylinder 24 can be sucked in, and at the same time, the dust inside the arc box 2 can be sucked into the second cylinder 24 and enter the dust collecting bag 26 for collection, and then the support frame 1 is driven to drive the blade 15 to cut around the outside of the damaged part of the road surface until the cutting is completed, and the arc box 2 is arranged on one side of the blade 15, and the air inside the second cylinder 24 is extracted, so that the dust and impurities inside the arc box 2 pass through the second cylinder 24 into the dust collecting bag 26 for collection, thereby solving the problem that dust is easily generated when cutting the ground in urban roads, which will cause pollution to the road environment and passers-by.

[0033] like Figure 4As shown, in this embodiment, the arc box 2 is respectively fixed with third rectangular blocks 23 on both sides of the lower end, and the third rectangular blocks 23 are connected with cylindrical blocks 231 for common rotation. A plurality of brushes 232 are fixed to the outer side of the cylindrical blocks 231. The lower end of the arc box 2 is provided with a plurality of rectangular grooves 21, and the brushes 232 can slide in the rectangular grooves 21.

[0034] Specifically, the larger particles generated during cutting cannot be sucked into the dust bag 26 due to gravity, but fall to the ground. The cylindrical block 231 is electrically controlled to drive the cylindrical block 231 to rotate, driving the outer brush 232 to rotate, scooping up the particles on the ground, and then bringing them into the arc box 2, so that the brush 232 can pass through several rectangular grooves 21, and the impurities in the brush 232 can be scraped off and left in the arc box 2 for collection.

[0035] like Figure 5 As shown, in this embodiment, one-way valves 241 are respectively installed on both sides of the inside of the second cylinder 24. The one-way valve 241 close to the arc box 2 is set to flow into the second cylinder 24, and the one-way valve 241 close to the dust bag 26 is set to flow into the dust bag 26.

[0036] Specifically, one-way valves 241 are provided at both ends of the second cylinder 24 so that dust can only enter the dust bag 26 from the second cylinder 24 and cannot come out, and dust remaining in the second cylinder 24 is prevented from falling out when the slitting machine is moved.

[0037] like Figure 3 , 5 As shown, in this embodiment, a rectangular plate 3 is fixedly connected to one side of the support frame 1, and support columns 4 are fixedly connected to both ends of one side of the rectangular plate 3. The upper ends of the support columns 4 are rotatably connected to a third cylindrical bar 42, and the lower ends of the support columns 4 are rotatably connected to a second cylindrical bar 41. Both ends of the second cylindrical bar 41 respectively penetrate the support columns 4, and both ends of the second cylindrical bar 41 are respectively fixed to wheels 411. A piston 252 is slidably connected to the inside of the third cylinder 25, and a first connecting rod 2521 is fixedly connected to one side of the piston 252, and one end of the first connecting rod 2521 is rotatably connected to the second connecting rod 2522, and the second cylindrical bar 41 is connected to the second connecting rod 2522 through a first transmission group, and the first transmission group includes second sprockets 2523 respectively fixed to the middle part of the second cylindrical bar 41 and one side of the second connecting rod 2522, and the two second sprockets 2523 are driven by a second chain 2524.

[0038] Specifically, when the slitting machine is driven to cut, the third cylindrical bar 42 is pushed, and the wheel 411 is pushed to rotate through the support column 4, and the wheel 411 drives the second cylindrical bar 41 to rotate, and the second cylindrical bar 41 drives the two second sprockets 2523 of the first transmission group to rotate, and the second sprocket 2523 drives the second connecting rod 2522 to rotate, and the second connecting rod 2522 drives the piston 252 to slide back and forth in the third cylinder 25 through the first connecting rod 2521. When the piston 252 slides away from the end of the second cylinder 24, the piston 252 in the second cylinder 24 is pushed back and forth. The air is extracted, and the dust in the arc box 2 enters the second cylinder 24 through the one-way valve 241 near the side of the arc box 2. Then, when the piston 252 slides toward the end near the second cylinder 24, it squeezes the air inside the second cylinder 24, so that the dust in the second cylinder 24 enters the dust bag 26 through the one-way valve 241 near the end of the dust bag 26. Since the one-way valve 241 near the end of the arc box 2 is installed toward the inside of the second cylinder 24, it prevents the internal dust from being ejected from the arc box 2 when the air inside the second cylinder 24 is squeezed.

[0039] like Figure 5 As shown, a filter screen 251 is fixedly connected to one end of the third cylinder 25 near the second cylinder 24 in this embodiment.

[0040] Specifically, when vacuuming, dust needs to be passed from the second cylinder 24 into the dust bag 26 , and a filter 251 is installed at one end of the third cylinder 25 to prevent dust from entering the third cylinder 25 , and to prevent dust from adhering to the inner wall of the third cylinder 25 and hindering the sliding of the piston 252 .

[0041] like Figure 6 As shown, in the present embodiment, a second ring 253 is fixedly connected to one side of the third cylinder 25 close to the second cylinder 24, and a third ring 254 is fixedly connected to one side of the second ring 253 via a third spring 2531. The third ring 254 can slide inside the third cylinder 25, and the four corners of the third ring 254 are rotatably connected to L-shaped bars 256 via third connecting rods 255. The L-shaped bars 256 are rotatably connected to the inner walls of the third cylinder 25 respectively, and the ends of the L-shaped bars 256 can contact one side of the filter screen 251.

[0042] Specifically, after a long period of cutting, a lot of dust will adhere to the outside of the filter 251, which will cause the filter 251 to be blocked. When using the present invention, since the circular hole in the middle of the third ring 254 is smaller than the second ring 253, when the piston 252 slides, the third ring 254 will feel a certain suction force. When the piston 252 is driven to slide in the third cylinder 25 toward the side away from the second cylinder 24, the third ring 254 will feel a certain suction force at the same time, so that it slides in the third cylinder 25 toward the side away from the second cylinder 24 and squeezes the third spring 2531. The third ring 254 drives the L-shaped bar 256 to separate from the side of the filter 251 through the third connecting rod 255. When the piston 252 slides toward the side close to the second cylinder 24, the third spring 2531 releases the elastic force to push the third ring 254 toward the side close to the filter 251. The third ring 254 drives the L-shaped bar 256 to knock on the filter 251 through the third connecting rod 255, so that the dust attached to the surface of the filter 251 falls off.

[0043] like Figure 6 As shown, in this embodiment, a third rectangular bar 2541 is fixedly connected to the middle of the third ring 254, a screw rod 2542 is fixedly connected to one side of the third rectangular bar 2541, and the screw rod 2542 is threadedly connected to a fourth cylinder 257. The fourth cylinder 257 can rotate in the middle of the filter screen 251, and a scraper 2571 is fixedly connected to the end of the fourth cylinder 257, and the scraper 2571 is closely attached to one side of the filter screen 251.

[0044] Specifically, when the driving piston 252 drives the third ring 254 to move, the third ring 254 drives the screw rod 2542 to move inside the fourth cylinder 257 through the third rectangular bar 2541, and the movement simultaneously drives the fourth cylinder 257 to rotate. The fourth cylinder 257 drives the scraper 2571 to rotate on one side of the filter 251, scraping off impurities adhered to the side of the filter 251, and at the same time performing knocking and vibration, which has a better dust removal effect on the filter 251.

[0045] like Figure 7-8 As shown, in this embodiment, wiping and cooling components are respectively provided on both sides of the blade 15, and the wiping and cooling components include a first ring 17 rotatably connected to one side of the blade 15, a hollow cylinder 171 is fixedly connected to the upper end of the first ring 17, and a circular sponge 172 is installed on the outer side of the hollow cylinder 171, and a first cylinder 16 is slidably penetrated through the middle of the upper end of the arc cover 13, and the upper end of the first cylinder 16 is connected to the water tank 162 through a hose 161, and the water tank 162 is fixed to the rectangular plate 3, and a second rectangular block 163 is fixedly connected to the lower end of the first cylinder 16, and the interior of the second rectangular block 163 is a hollow structure, and the upper ends of the two hollow cylinders 171 can be installed in the second rectangular block 163.

[0046] Specifically, the blade 15 needs to be cooled down during cutting to prevent the blade 15 from being damaged. The traditional cooling method is to directly spray water on the blade 15. The cut dust merges with the water to form mud, which will adhere to the surface of the blade 15, thereby affecting the cutting effect of the blade 15. In addition, only a certain amount of water can be carried during outdoor construction, and spraying water for cooling will cause the water to be used too quickly. When using the present invention, hollow cylinders 171 are provided on both sides of the blade 15. The water in the water tank 162 is transported to the hose 161, and then flows from the hose 161 into the first cylinder 16, and then flows from the second rectangular block 163 into the hollow cylinder 171, and then flows from the hollow holes provided on the surface of the hollow cylinder 171 to the inside of the circular sponge 172. The circular sea The circular sponge 172 absorbs moisture, and the circular sponge 172 is close to both sides of the blade 15. When the blade 15 rotates, the moisture absorbed inside the circular sponge 172 contacts the blade 15, and the two sides of the blade 15 can be cooled down. By arranging the circular sponge 172 on both sides of the blade 15 and then injecting water into the circular sponge 172, the circular sponge 172 is close to both sides of the blade 15 to cool it down. The sponge has a certain water storage function to prevent a large amount of water from spilling out, and can cool down the surface of the blade 15 at the same time, which solves the problem of needing to sprinkle water to cool the blade 15 during cutting, so that the carried water can be used faster. At the same time, it solves the problem that the dust generated by cutting merges with water to form mud, which will adhere to the surface of the blade 15, thereby affecting the cutting effect of the blade 15.

[0047] like Figure 8 As shown, in this embodiment, the first cylindrical bars 164 are respectively fixedly connected to both sides of the upper end of the second rectangular block 163, and the first cylindrical bars 164 slide through the upper end of the arc cover 13 respectively. The second rectangular block 163 is fixedly connected to the inside of the arc cover 13 through the second spring 165, and the upper ends of the first cylindrical bars 164 are commonly fixedly connected to a rectangular frame 166.

[0048] Specifically, when the circular sponge 172 needs to be replaced, the rectangular frame 166 is pushed upward, and the second rectangular block 163 is driven to move upward through the first cylindrical bar 164, so that the second rectangular block 163 is separated from the hollow cylinder 171, and then the first ring 17 is rotated to drive the hollow cylinder 171 to rotate to the lower end of the blade 15, so that the circular sponge 172 can be replaced.

[0049] Embodiment 2: Figure 2As shown, compared with Example 1, another implementation of the present invention is: a rectangular hole 11 is opened at the upper end of the support frame 1, and a tensioning assembly is provided in the middle of the rectangular hole 11, and the tensioning assembly includes three first sprockets 141, the first sprocket 141 at the lower end is fixedly connected to the rotating shaft 14, and the first sprocket 141 at one side of the upper end is fixedly connected to the output end of the motor 147, and the motor 147 is fixedly connected to the upper end of the support frame 1, and the first sprocket 141 on the other side is rotatably connected to the first rectangular block 144 through a pin shaft on both sides, and several of the first sprockets 141 are driven by a first chain 142, and the lower ends of the first rectangular blocks 144 can slide in the rectangular box 145 respectively, and the first rectangular blocks 144 are fixedly connected to one side of the inside of the rectangular box 145 through a first spring 146.

[0050] Specifically, during cutting, the driving motor 147 drives several first sprockets 141 to rotate, and the first sprocket 141 at the lower end drives the blade 15 to rotate through the rotating shaft 14. When the driving blade 15 moves downward, the rotating shaft 14 drives the first sprocket 141 at the lower end to move downward, and the first sprocket 141 at the upper end side slides in the rectangular box 145 through the first rectangular block 144 and squeezes the first spring 146.

[0051] Working principle: during cutting, the third cylindrical bar 42 is pushed, and the wheel 411 is pushed to rotate through the support column 4, driving the support frame 1 to move, driving the blade 15 to be located at one side of the damaged road surface, and driving the plurality of first sprocket wheels 141 to rotate through the driving motor 147. The first sprocket wheel 141 at the lower end drives the blade 15 to rotate through the rotating shaft 14, and then drives the blade 15 to move downward so that the blade 15 extends into the ground for cutting. The rotating shaft 14 drives the first sprocket wheel 141 at the lower end to move downward, and the first sprocket wheel 141 at one side of the upper end slides in the rectangular box 145 through the first rectangular block 144 and squeezes the first spring 146;

[0052] When cutting, the machine needs to be moved to drive the blade 15 to move and cut a circle outside the damaged part of the ground. At this time, the wheel 411 drives the second cylindrical bar 41 to rotate, and the second cylindrical bar 41 drives the two second sprockets 2523 of the first transmission group to rotate. The second sprocket 2523 drives the second connecting rod 2522 to rotate, and the second connecting rod 2522 drives the piston 252 to slide back and forth in the third cylinder 25 through the first connecting rod 2521. When the piston 252 slides away from the end of the second cylinder 24, the air in the second cylinder 24 is extracted, and the arc box 2 The dust inside enters the second cylinder 24 through the one-way valve 241 near the side of the arc box 2, and then when the piston 252 slides toward the end near the second cylinder 24, it squeezes the air inside the second cylinder 24, so that the dust inside the second cylinder 24 enters the dust bag 26 through the one-way valve 241 near the end of the dust bag 26. Since the one-way valve 241 near the end of the arc box 2 is installed toward the inside of the second cylinder 24, it prevents the internal dust from being ejected from the arc box 2 when squeezing the air inside the second cylinder 24, and the dust generated during cutting can be collected;

[0053] When vacuuming, dust needs to be allowed to enter the dust bag 26 from the second cylinder 24. A filter screen 251 is installed at one end of the third cylinder 25 to prevent dust from entering the third cylinder 25 and to prevent dust from adhering to the inner wall of the third cylinder 25 and hindering the sliding of the piston 252. After a long period of cutting, a lot of dust will adhere to the outer side of the filter screen 251, thereby causing the filter screen 251 to be blocked. When using the present invention, since the circular hole in the middle of the third ring 254 is smaller than that of the second ring 253, when the piston 252 slides, the third ring 254 will feel a certain suction force. When the driving piston 252 slides in the third cylinder 25 toward the side away from the second cylinder 24, the third ring 254 will feel a certain suction force at the same time, thereby sliding in the third cylinder 25 toward the side away from the second cylinder 24 and squeezing the third spring 2531. The third ring 254 is connected to the third ring 254 through the third The rod 255 drives the L-shaped bar 256 to separate from one side of the filter 251. When the piston 252 slides toward the side close to the second cylinder 24, the third spring 2531 releases its elastic force to push the third ring 254 toward the side close to the filter 251. The third ring 254 drives the L-shaped bar 256 to knock the filter 251 through the third connecting rod 255, so that the dust attached to the surface of the filter 251 falls off. When the driving piston 252 drives the third ring 254 to move, the third ring 254 drives the screw rod 2542 to move inside the fourth cylinder 257 through the third rectangular bar 2541, and the movement simultaneously drives the fourth cylinder 257 to rotate. The fourth cylinder 257 drives the scraper 2571 to rotate on one side of the filter 251, scrapes off the impurities attached to the side of the filter 251, and performs knocking and vibration at the same time, so as to have a better dust removal effect on the filter 251.

[0054] When the blade 15 is cutting, it is necessary to cool down to prevent the blade 15 from being damaged. The traditional cooling method is to directly sprinkle water on the blade 15. The cut dust merges with the water to form mud, which will adhere to the surface of the blade 15, thereby affecting the cutting effect of the blade 15. In addition, only a certain amount of water can be carried during outdoor construction, and sprinkling water for cooling will cause the water to be used too quickly. When using the present invention, hollow cylinders 171 are provided on both sides of the blade 15. The water in the water tank 162 is transported to the hose 161, and then flows from the hose 161 into the first cylinder 16, and then flows from the second rectangular block 163 into the hollow cylinder 171, and then flows from the hollow holes provided on the surface of the hollow cylinder 171 to the inside of the circular sponge 172. The circular sponge 1 72 absorbs moisture, and the circular sponge 172 is close to both sides of the blade 15. When the blade 15 rotates, the moisture absorbed inside the circular sponge 172 contacts the blade 15, which can cool down both sides of the blade 15. By arranging the circular sponge 172 on both sides of the blade 15 and then injecting water into the circular sponge 172, the circular sponge 172 is close to both sides of the blade 15 to cool it. The sponge has a certain water storage function to prevent a large amount of water from spilling out, and can cool the surface of the blade 15 at the same time, which solves the problem of needing to sprinkle water to cool the blade 15 during cutting, so that the carried water can be used faster. At the same time, it solves the problem that the dust generated by cutting merges with water to form mud, which will adhere to the surface of the blade 15, thereby affecting the cutting effect of the blade 15.
