[0033] See also Figures 1-9 , the present invention provides a technical solution:

[0034] A vertical cutting device for road and bridge construction includes a cutting machine 10, a water spray head 1 is provided on the side of the cutting machine 10, a scraping assembly 2 is provided on the side wall of the water spray head 1, the scraping assembly 2 is used to remove mortar, a grinding assembly 4 is provided in the middle of the scraping assembly 2, the grinding assembly 4 is used to grind large pieces of mortar, and a lifting assembly 5 is provided at the end of the grinding assembly 4, the lifting assembly 5 is used to clear the water outlet of the water spray head 1;

[0035] The user twists the scraping assembly 2 by hand to rotate. Because the water spray head 1 has been used for a long time, some gravel will enter the inner wall of the water spray head 1 and accumulate. At this time, the rotating scraping assembly 2 will scrape and clean the mortar adsorbed on the inner wall of the water spray head 1 to avoid excessive accumulation and blockage. When the scraping assembly 2 is in motion, it will drive the grinding assembly 4 to move. At this time, the rotation of the grinding assembly 4 will grind the continuously rotating scraping assembly 2, so that the mortar accumulated when the scraping assembly 2 is scraping the mortar will be ground to avoid excessive accumulation of mortar on the scraping assembly 2, thereby affecting the cleaning effect of the scraping assembly 2. At this time, the grinding assembly 4 will drive the top material assembly 5 to rotate, so that the top material assembly 5 will reciprocate and insert the water outlet of the water spray head 1 to clean the blocked gravel.

[0036] As a further solution of the present invention, the scraping assembly 2 includes: a support frame 21, a scraping member 22, a limiting frame member 23, a fork rod 24, a toggle member 25, a bevel gear 251, a toggle bevel gear rod 26, and a twist handle 261. One end of the support frame 21 is fixedly connected to the side wall of the sprinkler head 1, the middle part of the support frame 21 is rotatably connected to the end of the limiting frame member 23, the groove of the limiting frame member 23 is slidably connected to the end of the fork rod 24, the middle part of the fork rod 24 is rotatably connected to one end of the toggle member 25, and the toggle member 26 is fixedly connected to the side wall of the sprinkler head 1. The other end of the moving member 25 is fixedly connected to the middle of the bevel gear 251, the column of the bevel gear 251 is rotatably connected to the frame of the support frame 21, the bevel gear 251 is meshed with the teeth of the toggle bevel gear rod 26, the rod body of the toggle bevel gear rod 26 penetrates and is rotatably connected to the side wall of the sprinkler head 1, the end of the toggle bevel gear rod 26 is fixedly connected to the middle of the twist handle 261, the fork of the fork rod 24 is movably connected to the upper part of the scraper 22, and the middle column of the scraper 22 is rotatably connected to the frame of the support frame 21;

[0037] The scraper 22 further includes: a cylindrical block 221 and a scraper 222. The upper portion of the scraper 22 is fixedly connected to the end of the cylindrical block 221, and the end of the scraper 22 is fixedly connected to the upper portion of the scraper 222.

[0038] The user twists the handle 261, and the handle 261 drives the bevel gear rod 26 to rotate, and the bevel gear rod 26 drives the bevel gear 251 to rotate. The bevel gear 251 is fixedly connected to one end of the toggle member 25, and the other end of the toggle member 25 is rotatably connected to the rod body of the fork rod 24. Therefore, when the bevel gear 251 drives the toggle member 25 to rotate, the toggle member 25 first drives the rod body of the fork rod 24 to move toward the cavity of the limit frame 23. At this time, the fork head of the fork rod 24 will first toggle the cylindrical block 221 during the movement, so that the cylindrical block 221 drives the scraping member 22 to rotate, and then as the fork rod 24 moves in the cavity toward the limit frame 23 Contraction, as the toggle member 25 continues to rotate, the toggle member 25 will drive the fork rod 24 to extend out of the cavity of the limit frame member 23 again and move toward the position of the next cylindrical block 221 until the fork head of the fork rod 24 is stuck in the cylindrical block 221 again, and then repeat the above action, so that the cylindrical block 221 drives the scraper 22 to rotate. At this time, the scraper 22 fixed at the end of the scraper 22 will scrape off the mortar adsorbed on the inner wall of the sprinkler head 1, and the scraper 222 has small edges and corners that make it easier to scrape off the mortar. At this time, part of the mortar will fall to the lower part of the sprinkler head 1, and part of the mortar will accumulate on the scraper 222.

[0039] The scraping assembly 2 can scrape off the mortar adsorbed on the inner wall of the sprinkler head 1, thereby preventing the mortar from being not cleaned in time, causing the mortar to become large pieces of mortar, thereby affecting the water output of the sprinkler head 1.

[0040] As a further solution of the present invention, the grinding assembly 4 includes: a top plate column 41, a thrust piece 42, a push rod 421, a grinding column 43, a bevel gear column 431, a power gear column 44, a sliding bevel gear 45, an L-shaped frame 46, and a support plate 47. The rod body of the top plate column 41 is fixedly connected to the middle part of the scraping assembly 2, the end of the support plate 47 is fixedly connected to the inner wall of the water spray head 1, the frame of the support plate 47 is rotatably connected to the rod body of the power gear column 44, and the teeth of the power gear column 44 are engaged with the upper part of the ejection assembly 5. The end of the power gear column 44 is slidably connected to the middle of the sliding bevel gear member 45, and the end of the sliding bevel gear member 45 is rotatably connected to one end of the L-shaped frame 46. The other end of the L-shaped frame 46 is rotatably connected to the rod body of the bevel gear column 431. The bevel gear column 431 is meshed and connected to the sliding bevel gear member 45. The rod body of the bevel gear column 431 is fixedly connected to the middle of the grinding column 43. The middle part of the rod body of the bevel gear column 431 is rotatably connected to one end of the push rod 421. The other end of the push rod 421 is fixedly connected to the middle of the thrust member 42.

[0041] The L-shaped frame 46 further includes: a spring 461 and a sliding post 462. The frame of the L-shaped frame 46 is fixedly connected to one end of the sliding post 462. The other end of the sliding post 462 passes through a hole slidably connected to the support plate 47. The outer wall of the sliding post 462 is sleeved with a spring 461.

[0042] When the scraper 22 rotates, the top plate column 41 fixedly connected to the scraper 22 will rotate synchronously. At this time, the ejecting assembly 5 at the lower part of the top plate column 41 will also be driven. Because the power gear column 44 is engaged with the upper part of the ejecting assembly 5, the ejecting assembly 5 will drive the power gear column 44 to rotate. When the long axis end of the top plate column 41 rotates, it will press against the thrust piece 42. The thrust piece 42 is fixedly connected to the push rod 421, so the push rod 421 will drive the grinding column 43 to move. Because the bevel gear column 431 is rotatably connected to one end of the L-shaped frame 46, and the other end of the L-shaped frame 46 is rotatably connected to the sliding bevel gear 45, the bevel gear column 431 will drive the sliding bevel gear 45 to slide toward the guide rail portion of the power gear column 44 through the L-shaped frame 46. At this time, the sliding bevel gear 45 will move on the guide rail portion of the power gear column 44 toward the scraper 222. At this time, the sliding column 462 will also slide under the restriction of the support plate 47. During the movement of the L-shaped frame 46, the spring 1 461 will also be stretched accordingly. Because the power gear column 44 is driven to rotate by the ejecting assembly 5, the power gear column 44 will drive the guide rail portion at the end of the power gear column 44 to rotate. Because the middle part of the sliding bevel gear 45 is engaged with the guide rail portion of the power gear column 44, the power gear column 44 will drive the sliding bevel gear 45 to rotate, and the sliding bevel gear 45 will drive the grinding column 43 to rotate through the bevel gear column 431. At this time, the grinding column 43 will clean the mortar accumulated on the scraper 222.

[0043] Through the cooperation between the scraping assembly 2 and the grinding assembly 4, after the scraping assembly 2 cleans the mortar on the side wall of the water spray head 1, the grinding assembly 4 will promptly clean the mortar accumulated on the scraper 222, thereby avoiding excessive mortar accumulation on the scraper 222, which will affect the cleaning effect of the subsequent scraping assembly 22 on the side wall of the water spray head 1.

[0044] As a further solution of the present invention, the top material assembly 5 includes: a linkage tooth column 51, a force plate 52, a track member 521, a second spring 53, a limiting column 54, and a dredging column 55. One end of the linkage tooth column 51 is fixedly connected to the middle part of the top plate column 41, and the linkage tooth column 51 is meshed with the teeth of the power tooth column 44. A force plate 52 is provided at the water outlet of the sprinkler head 1. A plurality of track members 521 are fixedly connected to the side of the force plate 52. The holes of the track members 521 are slidably connected to the limiting column 54. The end of the limiting column 54 is fixedly connected to the inner wall of the sprinkler head 1. The middle part of the dredging column 55 is fixedly connected to the end of the dredging column 55. A plurality of second springs 53 are provided on the side of the force plate 52.

[0045] The linkage gear column 51 further includes: a positioning base plate 511 and a pressure column 512. The end of the linkage gear column 51 is fixedly connected to the middle of the positioning base plate 511, and the end of the positioning base plate 511 is fixedly connected to the end of the pressure column 512.

[0046] When the top plate column 41 rotates, because the lower part of the top plate column 41 is fixedly connected to the upper end of the linkage gear column 51, the top plate column 41 will drive the linkage gear column 51 to rotate, and the linkage gear column 51 is engaged with the power gear column 44, so the linkage gear column 51 will drive the power gear column 44 to move, and because the linkage gear column 51 is fixedly connected to the positioning base plate 511, the linkage gear column 51 will drive the pressure column 512 to rotate through the positioning base plate 511, and when the pressure column 512 rotates to the arc edge of the force plate 52, the pressure column 512 will press against the force plate 52 toward the water spray When the water outlet of the sprinkler head 1 is moved, the force plate 52 is fixedly connected to the dredging column 55, so the force plate 52 will drive the dredging column 55 to be inserted into the water outlet of the sprinkler head 1. Because track parts 521 are provided at both ends of the force plate 52, and the holes of the track parts 521 are slidably connected to the limiting columns 54, the movement of the force plate 52 will drive the track parts 521 to slide under the restriction of the limiting columns 54, and the two springs 2 53 at the lower part of the force plate 52 will also be compressed and stored. When the pressure column 512 cannot squeeze the force plate 52, the spring 2 53 will drive the force plate 52 to reset.

[0047] The setting of the top material component 5 can enable some gravel stuck in the water outlet of the sprinkler head 1 to be cleared out of the water outlet of the sprinkler head 1 through the reciprocating insertion and withdrawal of the top material component 5, thereby preventing the accumulated gravel mixed with mortar from blocking the water outlet of the sprinkler head 1.

[0048] As mentioned above, the cutting method for road and bridge construction includes the following specific steps:

[0049] Step 1: Turn the scraping assembly 2 to clean the mortar adsorbed on the inner wall of the sprinkler head 1 to avoid excessive accumulation;

[0050] Step 2: When the scraping component 2 is in motion, it drives the grinding component 4 to move. At this time, the grinding component 4 will grind the mortar accumulated on the scraping component 2;

[0051] Step 3: The grinding component 4 will drive the pushing component 5 to rotate, and the pushing component 5 will reciprocate the water outlet of the sprinkler head 1 to clean the blocked gravel.
