When the drilling tube 52 moves to the bottom of the borehole, multiple arc-shaped prying plates 514 contact the slag blocks. The multiple arc-shaped prying plates 514 rotate to pry the slag blocks from the inside to the outside, so that the slag blocks at the center of the bottom of the borehole move outward to below the multiple lifting plates 515. When the multiple lifting plates 515 rotate, the contacted slag blocks are pushed upward along the inclined surfaces of the multiple lifting plates 515.

The slag blocks in the inclined funnel 64 fall into the fine slag area on the right side of the partition plate 66 through the outlet below, and the slag blocks with larger particle sizes move outwards by centrifugal force until they are separated from the screen 63. The slag blocks separated from the screen 63 fall onto the inclined guide plate 65 through the gaps between the multiple short rods 62, and the slag blocks with larger particle sizes slide down the inclined guide plate 65 to the coarse slag area on the left side of the partition plate 66, thereby achieving the effect of classifying and collecting the slag blocks according to their different particle sizes, which is convenient for Subsequent staff used different paths; a sliding rod 67 was slidably installed on the inner wall of the slag bucket 512 through a bracket, a spring was arranged between the sliding rod 67 and the inner wall of the slag bucket 512, one end of the sliding rod 67 was connected to an arc block 68, and the other end of the sliding rod 67 was connected to a No. 1 hammer 69, a sliding groove was provided on the inner wall of the slag bucket 512, the arc block 68 was slidingly connected to the sliding groove of the slag bucket 512, the spiral piece 516 was in sliding contact with the arc block 68 during the movement, the arc block 68 protruded from the outer wall of the slag bucket 512, and the spiral piece 516 was closely attached to the outer wall of the slag bucket 512 and rotated, so that part of the spiral piece 516 would contact the arc block 68 during the rotation, and the No. 1 hammer 69 would be in sliding contact with the arc block 68 during the movement. During the movement, the No. 2 hammer 612 contacts the outer wall of the inclined funnel 64. The No. 1 hammer 69 can hit the outer wall of the inclined funnel 64 with a gentler slope, causing the inclined funnel 64 to vibrate, thereby promoting the slag blocks on the inclined funnel 64 with a gentler slope to slide down. The bottom surface of the inclined guide plate 65 is rotatably mounted with a rotating rod 610 through a bracket. One end of the rotating rod 610 is connected to a supporting plate 611.

Two square grooves are provided on the drilling tube 52, and the two outer push plates 76 are respectively slidably connected with the two square grooves of the drilling tube 52. When the outer push plate 76 moves outward, it protrudes from the square groove of the drilling tube 52 to the outer surface of the drilling tube 52 and contacts the inner wall of the borehole. In the process of the drilling tube 52 moving downward, the two outer The push plate 76 continuously protrudes outward to squeeze the inner wall of the borehole, compacting the inner wall of the borehole to prevent the loose slag blocks on the inner wall of the borehole from falling again during and after the cleaning process; through the arrangement of the hole wall reinforcement device 7, during the process of cleaning the borehole, the two outer push plates 76 compact the inner wall of the borehole by continuously protruding outward from the outer surface of the drilling tube 52, pressing the loose slag blocks into the soil layer, thereby achieving the effect of reinforcing the inner wall of the borehole, and preventing the loose slag blocks from falling into the borehole again after the cleaning is completed, affecting the quality of the project.

[0049] Embodiment 2: A method for using a road and bridge pile foundation efficient slag cleaning device, using the road and bridge pile foundation efficient slag cleaning device in Embodiment 1, further comprising the following steps:

[0050] Step 1: Connect the sling to the connecting flange on the top seat 1 by bolts;

[0051] Step 2: Fix the sling on the lifting machinery;

[0052] Step 3: Move the lifting machinery so that the drilling tube 52 is located directly above the drill hole;

[0053] Step 4: Start the motor 3, and the drilling tube 52 and the slag bucket 512 begin to rotate;

[0054] Step 5: Control the lifting machinery to lower the drilling tube 52 into the borehole;

[0055] Step 6: When the drilling tube 52 moves downward, the drilling tube 52 knocks down the loose slag blocks on the inner wall of the borehole. After the drilling tube 52 reaches the bottom of the borehole, the multiple arc-shaped shifting plates 514 shift the slag blocks at the bottom of the borehole outward, and the multiple lifting plates 515 lift the contacted slag blocks upward, and the spiral pieces 516 lift the slag blocks into the slag bucket 512 by means of spiral lifting;

[0056] Step seven: control the crane to lift the drilling tube 52. After the drilling tube 52 leaves the borehole, place the drilling tube 52 on the ground, open the buckle 8, lift the drilling tube 52 again, open the bottom cover 513, and the slag blocks in the slag bucket 512 fall to the ground. Move the drilling tube 52 away, close the bottom cover 513 and clean the slag blocks, and the slag cleaning operation is completed.

[0057] With the above structure, the working principle of this case is that the staff fixes the top seat 1 on the hanger through the connecting flange, and then fixes the hanger on the lifting machinery, and lifts the top seat 1 to the top of the borehole through the lifting machinery, and turns on the motor 3, the motor 3 drives the driving gear 4 to rotate, the driving gear 4 drives the outer gear ring 2 to rotate, the outer gear ring 2 drives the connecting frame 51 to rotate, the connecting frame 51 drives the drilling tube 52 to rotate, and the top seat 1 is driven downward by the starter, and the drilling tube 52 moves downward accordingly. When the drilling tube 52 moves downward, the multiple drill teeth at the bottom of the drilling tube 52 can clean the inner wall of the borehole, so that the loose slag blocks fall to the bottom of the borehole. When the drilling tube 52 rotates, the top seat 1, the connecting column 54, the layer plate 55 and the short shaft 56 do not rotate, and the drilling tube 52 When the inner gear ring 53 rotates, the inner gear ring 53 drives the sun gear 57 to rotate through a plurality of planetary gears 58. The sun gear 57 drives the second layer plate 510 to rotate through four arc frames 59. The second layer plate 510 drives the slag bucket 512 to rotate through the fixed column 511. The rotation direction of the slag bucket 512 is opposite to that of the drilling tube 52. When the slag bucket 512 rotates, it drives the bottom cover 513 and a plurality of lifting plates 515 to rotate. The bottom cover 513 drives a plurality of arc-shaped shifting plates 514 to rotate. When the drilling tube 52 moves to the bottom of the borehole, the plurality of arc-shaped shifting plates 514 contact the slag blocks. The plurality of arc-shaped shifting plates 514 rotate to shift the slag blocks from the inside to the outside, so that the slag blocks at the center of the bottom of the borehole move outward to the plurality of lifting plates 515. At the bottom, when the multiple lifting plates 515 rotate, the slag blocks they contact are pushed upward along the inclined surfaces of the multiple lifting plates 515. When the slag blocks move to above the top of the lifting plates 515, the spiral pieces 516 rotating along with the drilling tube 52 contact the slag blocks and lift the slag blocks upward. When the slag blocks are lifted to the top of the spiral pieces 516, they fall into the slag bucket 512. The slag bucket 512 collects the slag blocks, thereby achieving the effect of cleaning the bottom of the borehole; while the slag bucket 512 rotates, the slag bucket 512 drives the multiple rotating shafts 517 to rotate. When the rotating shafts 517 rotate, they drive the driven gears 518 to revolve around the slag bucket 512 as the center of the circle. When the driven gears 518 revolve, they rotate by meshing with the annular rack 519. When rotating, it drives the rotating shaft 517 to rotate, and the rotating shaft 517 drives the multiple crushing knives 520 to rotate. When the slag blocks between two adjacent lifting plates 515 flip upward, the multiple crushing knives 520 crush the larger slag blocks by rotating, so as to prevent the larger slag blocks from being stuck on the lifting plate 515 or the spiral piece 516 and causing material blockage. By setting the slag cleaning device 5, the multiple arc-shaped paddles 514 first pry the slag blocks at the bottom of the borehole outward, and the multiple lifting plates 515 then pry the slag blocks upward, and the spiral piece 516 lifts the slag blocks into the slag bucket 512 for collection by rotating, so as to achieve the effect of cleaning the bottom of the borehole, the cleaning coverage is relatively comprehensive, the cleaning effect is better, and it is avoided that a large amount of slag blocks are deposited at the bottom of the borehole and cannot be effectively cleaned;Through the arrangement of multiple crushing knives 520, the multiple crushing knives 520 can crush the slag blocks they come into contact with by rotating, so that larger slag blocks are crushed when they are turned upward through the multiple lifting plates 515, thereby preventing larger slag blocks from being blocked in the movement path of the slag blocks, thereby affecting the cleaning effect. ;

[0058] During the construction process, the slag blocks can be utilized, and the slag blocks of different particle sizes are utilized in different ways. The slag blocks falling into the slag bucket 512 first fall on the upper funnel 61, and then fall on the center of the screen 63 through the outlet at the bottom of the upper funnel 61. As the slag bucket 512 rotates, the upper funnel 61 and the screen 63 are driven to rotate synchronously, so that the slag blocks on the screen 63 generate centrifugal force and roll outward. The slag blocks with smaller particle sizes on the screen 63 pass through the screen 63 and fall into the inclined funnel 64. The partition 66 divides the lower half of the slag bucket 512 into two areas. The partition 66 The right side of the partition 66 is the fine slag area, and the left side of the partition 66 is the coarse slag area. The slag blocks in the inclined funnel 64 fall into the fine slag area on the right side of the partition 66 through the outlet at the bottom, and the slag blocks with larger particle sizes move outwards due to centrifugal force until they are separated from the screen 63. The slag blocks separated from the screen 63 fall onto the inclined guide plate 65 through the gaps between the multiple short rods 62, and the slag blocks with larger particle sizes slide down the inclined guide plate 65 to the coarse slag area on the left side of the partition 66, achieving the effect of classifying and collecting the slag blocks according to different particle sizes, which is convenient for subsequent staff to use them in different paths; the bottom outlet of the inclined funnel 64 is the inclined The center is set so that the slope of the right half of the inclined funnel 64 is larger, and the slope of the left half is gentler. Since the arc block 68 protrudes from the outer wall of the slag bucket 512, and the spiral piece 516 rotates closely against the outer wall of the slag bucket 512, a part of the spiral piece 516 will contact the arc block 68 during rotation. When the spiral piece 516 contacts the arc block 68, the spiral piece 516 pushes the arc block 68 toward the inclined funnel 64. The arc block 68 drives the first hammer 69 to move toward the inclined funnel 64 through the sliding rod 67, so that the first hammer 69 hits the inclined funnel. The outer wall of the side with a gentler slope 64 makes the inclined funnel 64 vibrate, promoting the slag blocks at the gentler slope of the inclined funnel 64 to slide down, avoiding local blockage. When the slag blocks in the inclined funnel 64 fall through the outlet, some of the slag blocks will hit the supporting plate 611, so that the supporting plate 611 pushes the left end of the rotating rod 610 downward, so that the rotating rod 610 drives the second hammer 612 to move upward through the lever principle. When the second hammer 612 moves upward, it hits the bottom surface of the top of the inclined guide plate 65, causing the inclined guide plate 65 to vibrate, promoting the slag blocks on the inclined guide plate 65 to slide down.When the cleaning is completed, the drilling tube 52 is placed on the ground by a lifting machine, and the staff uses a pry bar to penetrate through the gap between the drill teeth at the bottom of the drilling tube 52, press against the rebound push block 84 and push it, so that when the rebound push block 84 moves to the left, the inclined surface lock buckle 83 is pushed to the left, and the inclined surface lock buckle 83 no longer presses against the buckle of the lower locking block 82 after moving to the left. At this time, the lower locking block 82 is separated from the upper locking block 81, and the lifting machine lifts the top seat 1 again, and the slag bucket 512 moves upward, and the slag blocks inside it open the bottom cover 513 by gravity, and the slag blocks inside the slag bucket 512 fall to the ground, and the coarse slag blocks and the fine slag blocks are divided into two piles and stacked together. After the slag bucket 512 is empty, the lifting machine puts the drilling tube 52 on the ground again, presses against the bottom cover 513 through the ground, so that the lower locking block 82 and the upper locking block 81 fit together again, and the inclined surface lock buckle 83 The buckle 83 uses its own inclined surface and the elastic force of the spring to slide into the buckle bottom of the lower locking block 82 to achieve the locking effect. The setting of the buckle lock 8 makes it easy for the staff to open the bottom cover 513; through the setting of the screening device 6, the inclined funnel 64 and the inclined guide plate 65 can separate the fine slag blocks with larger particle sizes and the coarse slag blocks with larger particle sizes to the two sides of the partition 66. When the slag blocks are unloaded after cleaning, the fine slag blocks and the coarse slag blocks are divided into two piles and stacked together, which is convenient for the staff to use the slag blocks of different particle sizes, reducing the steps of the staff to screen the slag blocks by themselves; through the setting of the No. 1 hammer 69 and the No. 2 hammer 612, the No. 1 hammer 69 can repeatedly hit the inclined funnel 64, and the No. 2 hammer 612 can repeatedly hit the inclined guide plate 65, which promotes the sliding of the slag blocks on the inclined funnel 64 and the inclined guide plate 65 to avoid material blockage. ;

[0059] When the arc frame 59 rotates following the sun gear 57, the short shaft 56 does not rotate. When the two arc frames 59 with sliding push rods 72 rotate, they drive the two sliding push rods 72 to rotate. The two sliding push rods 72 drive the two sliding shafts 73 to rotate along the elliptical groove 71. When the two sliding shafts 73 slide in the elliptical groove 71, they constantly repeat the process of approaching and separating from each other, so that the two sliding shafts 73 drive the two sliding push rods 72 to perform horizontal reciprocating motion. The two sliding push rods 72 drive the two arc push blocks 74 to perform horizontal reciprocating motion. The two arc push blocks 74 perform horizontal reciprocating motion while revolving around the short shaft 56 as the center of the circle. The two arc push blocks 74 will contact the two outer push plates 76 during the horizontal reciprocating motion. When the arc push blocks 74 contact the outer push plates 76, the arc push blocks 74 push the outer push plates 76 in the direction away from the short shaft 56. When the arc push blocks When the outer push plate 74 is not in contact with the outer push plate 76, the outer push plate 76 is reset by the spring between the inner slide seat 75, so that the two outer push plates 76 can move outward periodically. When the outer push plate 76 moves outward, it will protrude from the square groove of the drilling tube 52 to the outer surface of the drilling tube 52 and contact the inner wall of the borehole. In the process of the drilling tube 52 moving downward, the two outer push plates 76 continuously protrude outward to squeeze the inner wall of the borehole, compacting the inner wall of the borehole, and preventing the loose slag blocks on the inner wall of the borehole from falling again during and after the cleaning process; through the setting of the hole wall reinforcement device 7, in the process of cleaning the borehole, the two outer push plates 76 compact the inner wall of the borehole by continuously protruding outward from the outer surface of the drilling tube 52, pressing the loose slag blocks into the soil layer, thereby strengthening the inner wall of the borehole, and preventing the loose slag blocks from falling into the borehole again after the cleaning is completed, affecting the quality of the project.
