[0016] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] like Figure 1 - Figure 7 A sampling core device for pavement disease analysis shown in the figure comprises a coring mechanism 1, an outer frame 2 is fixedly installed on both sides of the coring mechanism 1, a support plate 3 is arranged below the outer frame 2, a material receiving mechanism 8 is arranged in front of the outer frame 2, and the material receiving mechanism 8 comprises an L-shaped plate 11, and the L-shaped plate 11 is movably arranged in front of the outer frame 2, a first connecting frame 4 is arranged at one end of the outer frame 2 away from the L-shaped plate 11, and the first connecting frame 4 is connected to the support plate 3 through a rotating shaft, a second connecting frame 5 is installed on the surface of the support plate 3 close to the material receiving mechanism 8, and a cylinder 6 is connected to the top of the second connecting frame 5 through a rotating shaft, a side plate 7 is fixedly installed on the side of the outer frame 2, and the output end of the cylinder 6 is connected to the side plate 7, and the L-shaped plate A knocking mechanism 26 is arranged inside 11, and a connecting rod mechanism 10 is arranged on the surface of the L-shaped plate 11 close to the outer frame 2. By arranging the cylinder 6, when the cylinder 6 drives the side plate 7 to move upward, the front end of the outer frame 2 will drive the coring mechanism 1 to rotate backward with the first connecting frame 4 as the center, and adjust the angle of the coring mechanism 1. By arranging a material receiving mechanism 8 in front of the coring mechanism 1, the material receiving mechanism 8 will also rotate while the outer frame 2 rotates, which provides convenience for the subsequent material receiving operation. Finally, under the action of the connecting rod mechanism 10 and the knocking mechanism 26, the rock can be quickly taken out from the inside of the drill bit, which reduces manual intervention and greatly improves the speed of rock material removal.
[0018] A limit plate 14 is fixedly installed on the surface of the support plate 3, and a path groove 15 is opened on the surface of the limit plate 14. Bosses 16 are arranged at the bending parts of both ends of the L-shaped plate 11, and the surface of the bosses 16 is movably arranged in the path groove 15. A cross plate 9 is fixedly installed between the two outer frames 2, and the cross plate 9 is installed at the bottom of the front end of the outer frame 2. When the outer frame 2 rotates backward, the outer frame 2 exerts a certain thrust on the bottom of the L-shaped plate 11, so that the boss 16 moves forward along the path groove 15, and the path groove 15 guides the L-shaped plate 11.
[0019] A T-shaped groove 13 is provided at the front end of the outer frame 2, and a T-shaped slider 12 is fixedly installed on the L-shaped plate 11 near the top of the outer frame 2. The surface of the T-shaped slider 12 is slidably installed inside the T-shaped groove 13. When the boss 16 moves forward along the path groove 15, the outer frame 2 will also drive the L-shaped plate 11 to rotate backward as a whole. Since the boss 16 slides in the path groove 15, the L-shaped plate 11 will rotate around the boss 16, and the T-shaped slider 12 will gradually slide to the bottom of the T-shaped groove 13, and the surface of the L-shaped plate 11 can always remain parallel to the outer frame 2.
[0020] An expansion groove is provided at the middle end of the bottom of the L-shaped plate 11, and the expansion groove can facilitate the drill bit inside the coring mechanism 1 to drill into the road surface, and prevent the L-shaped plate 11 from interfering with the drill bit. Two straight grooves 17 are symmetrically provided on the surface of the L-shaped plate 11, and sliding blocks are arranged inside the straight grooves 17. The front ends of the two sliding blocks are respectively installed with a first support plate 18 and a second support plate 19. The connecting rod mechanism 10 includes two stoppers 20, and the two stoppers 20 are respectively fixedly installed at the upper and lower ends of the L-shaped plate 11. A first guide rod 21 is arranged between the two stoppers 20, and the surface of the first guide rod 21 is slidably provided with A movable block 23, connecting rods 24 are installed at both ends of the movable block 23 through a rotating shaft, and the other ends of the two connecting rods 24 are respectively connected to the two sliding blocks through the rotating shaft. A first spring 22 is arranged above the movable block 23, and the first spring 22 is arranged on the surface of the first guide rod 21. When the movable block 23 moves upward, the first spring 22 contracts, and the movable block 23 drives the first support plate 18 and the second support plate 19 to move toward the middle of the L-shaped plate 11 through the connecting rods 24 at both ends. The first support plate 18 and the second support plate 19 can be moved to the bottom of the drill bit, which is convenient for collecting the rock mass.
[0021] Two push blocks 25 are symmetrically installed at the front end of the cross plate 9. The two push blocks 25 are arranged below the movable block 23, and the two push blocks 25 are respectively located on both sides of the first guide rod 21. When the outer frame 2 rotates backward, the push blocks 25 will rotate synchronously. At this time, the push blocks 25 have an extrusion effect on the surface of the L-shaped plate 11, so that the L-shaped plate 11 will rotate around the boss 16, and the T-shaped slider 12 will gradually slide to the bottom of the T-shaped slot 13, so that the push blocks 25 can push the movable block 23 to the top of the L-shaped plate 11, so that when the outer frame 2 rotates backward, the coring mechanism 1 and the material receiving mechanism 8 will tilt, and the first support plate 18 and the second support plate 19 can be moved to just below the drill bit, thereby facilitating the collection of the rock mass.
[0022] The horizontal height of the first pallet 18 is higher than that of the second pallet 19 . When the first pallet 18 and the second pallet 19 move toward the middle of the L-shaped plate 11 , the first pallet 18 will be above the second pallet 19 , and the first pallet 18 and the second pallet 19 will overlap.
[0023] The knocking mechanism 26 includes a second guide rod 29, which is fixedly mounted inside the L-shaped plate 11. A second spring 30 is arranged on the surface of the second guide rod 29. A disc 31 is arranged at the front end of the second spring 30. A knocking rod 32 is arranged at the front end of the disc 31. The surface of the knocking rod 32 protrudes from the L-shaped plate 11. The surface of the second guide rod 29 movably penetrates the disc 31 and the knocking rod 32. Two extending columns 33 are symmetrically mounted at the upper and lower ends of the disc 31. The extending columns 33 are parallel to the second guide rod 29. An extrusion column 34 is fixedly mounted at the end of the extending column 33. A column is mounted on the surface of one of the sliding blocks. The column is slidably arranged in the L-shaped plate 11. Two push-pull columns are arranged at the top of the column. Rod 27, the surface of the push rod 27 is evenly provided with a plurality of protruding blocks 28, and the two push rods 27 correspond to the two extrusion columns 34 respectively. When the first support plate 18 and the second support plate 19 move toward the middle of the L-shaped plate 11, the column will drive the push rod 27 to move. At this time, the protruding blocks 28 on the surface of the push rod 27 can squeeze the extrusion columns 34 one by one. When the extrusion columns 34 are squeezed, the disc 31 and the knocking rod 32 will shrink toward the inside of the L-shaped plate 11, and the push rod 27 continues to move. When the next protruding block 28 squeezes the extrusion column 34, the elastic force of the second spring 30 will push the disc 31 and the knocking rod 32 outward, so that the knocking rod 32 can knock on the surface of the drill bit, which is convenient for removing the material from the rock mass.
[0024] Working principle: First, after the coring mechanism 1 coring the highway, the rock mass is fixed inside the drill bit, and then the cylinder 6 drives the side plate 7 to move upward. At this time, the front end of the outer frame 2 will drive the coring mechanism 1 to rotate backward with the first connecting frame 4 as the center, and adjust the angle of the coring mechanism 1. At the same time, during the rotation of the outer frame 2, the push block 25 has an extrusion effect on the surface of the L-shaped plate 11, so that the L-shaped plate 11 will rotate with the convex column 16 as the center, and the T-shaped slider 12 will gradually slide to the bottom of the T-shaped slide groove 13, so that the push block 25 can push the movable block 23 to the top of the L-shaped plate 11, so that when the outer frame 2 rotates backward, the coring mechanism 1 and the receiving mechanism 8 will tilt , and the first support plate 18 and the second support plate 19 can be moved to the bottom of the drill bit. Finally, when the first support plate 18 and the second support plate 19 move toward the middle of the L-shaped plate 11, the column will drive the push rod 27 to move. At this time, the protruding blocks 28 on the surface of the push rod 27 can squeeze the extrusion columns 34 one by one. When the extrusion columns 34 are squeezed, the disc 31 and the knocking rod 32 will shrink toward the inside of the L-shaped plate 11, and the push rod 27 continues to move. When the next protruding block 28 squeezes the extrusion column 34, the elastic force of the second spring 30 will push the disc 31 and the knocking rod 32 outward, so that the knocking rod 32 can knock on the surface of the drill bit, which is convenient for removing the rock mass.
