[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, a drilling and sampling tool for refractory bricks according to an embodiment of the present invention includes a workbench 1 and a sampling cylinder 20. Support arms 5 are symmetrically welded to both sides of the top of the workbench 1. A slide rod 6 is installed in the middle of the interior of the support arm 5. A bearing plate 7 is slidably connected to the outer periphery of the slide rod 6. A slide seat 10 is slidably connected to the middle of the interior of the bearing plate 7. Several sets of fourth hydraulic rods 17 are symmetrically installed on both sides of the slide seat 10, and the fourth hydraulic rods 17 are located inside the bearing plate 7. The sampling cylinder 20 is rotatably connected to the middle of the top of the slide seat 10. A transmission gear 14 is installed at the top of the surface of the sampling cylinder 20. One end of the transmission gear 14 is meshed with a drive gear 16, which is connected to the output end of a motor 15. The motor 15 is located at the top of the slide seat 10. Several sets of cutting teeth 21 are welded around the bottom of the sampling cylinder 20. A top plate 19 is rotatably connected to the middle of the worktable 1. A push rod 18 is welded to the middle of the top of the top plate 19. One end of the push rod 18 passes through one side of the sampling cylinder 20 and is connected to the connecting plate 12. A third hydraulic rod 11 is installed at the bottom of one side of the connecting plate 12. The third hydraulic rod 11 is located at the top of the slide block 10. Adjustment grooves 2 are symmetrically opened inside the worktable 1. A clamping plate 3 is slidably connected inside the adjustment groove 2. A first hydraulic rod 4 is installed at the bottom of one side of the clamping plate 3. The other end of the first hydraulic rod 4 is connected to the inner wall of the adjustment groove 2. The size of the top plate 19 is slightly smaller than the inner diameter of the sampling cylinder 20, so that the top plate 19 can move inside the sampling cylinder 20, thereby realizing the ejection of the refractory brick sample inside during sampling. This facilitates subsequent testing operations, reduces the difficulty and labor intensity of sample removal, and makes it easier to use.

[0028] In one embodiment, a top plate 8 is fixedly installed at the top of the support arm 5, and second hydraulic rods 9 are symmetrically installed on both sides of the bottom surface of the top plate 8. One end of the second hydraulic rod 9 is fixedly connected to the bearing plate 7. The first hydraulic rod 4, the second hydraulic rod 9, the third hydraulic rod 11, and the fourth hydraulic rod 17 are all common hydraulic rods, which will not be described in detail here. Personnel can flexibly select them according to different needs.

[0029] In one embodiment, a limiting disk 13 is installed on the surface of the sampling cylinder 20. The limiting disk 13 is provided to facilitate fixing the sampling cylinder 20 on the slide block 10, thereby ensuring that it can rotate smoothly under the operation of the motor 15, so as to realize the drilling and sampling of refractory bricks.

[0030] In one embodiment, a slot is provided inside the slide 10 for the limiting plate 13 to rotate. The slot is provided to facilitate the installation and rotation of the limiting plate 13 and to ensure its operational stability.

[0031] In one embodiment, a groove is provided inside the bearing plate 7 for sliding the slide block 10 and for installing the fourth hydraulic rod 17. The groove facilitates the movement of the slide block 10 under the push of the fourth hydraulic rod 17, thereby allowing the position of the sampling cylinder 20 to change, so as to perform sampling operations at different positions on the surface of the refractory brick, expand the sampling range, and at the same time, the mechanical adjustment can reduce the labor intensity of personnel and facilitate better use.

[0032] In one embodiment, a guide groove is provided on the surface of the support arm 5. The guide groove is provided to facilitate the connection between the bearing plate 7 and the slide rod 6. At the same time, the guide groove can also restrict the movement trajectory of the bearing plate 7 to ensure its movement stability.

[0033] In one embodiment, both the sampling cylinder 20 and the cutting teeth 21 are made of metal. The metal material is used to ensure the strength of the sampling cylinder 20 and the cutting teeth 21. Since metal is a common material and its production and application technologies are mature, the type of metal can be selected according to the requirements, which will not be elaborated on here.

[0034] In one embodiment, the clamping plate 3 has an L-shaped structure. The clamping plate 3 is designed to smoothly wrap and hold the refractory brick, thereby improving the stability and strength of the clamping, preventing the refractory brick from moving during drilling and sampling, thus ensuring the sampling effect.

[0035] Working Principle: In actual use, personnel can place the refractory brick to be sampled on the workbench 1. Then, by pushing out the two sets of first hydraulic rods 4, the clamping plate 3 can be moved closer to the refractory brick, thus clamping the refractory brick. Subsequently, by extending and retracting the first hydraulic rods 4, the refractory brick can be moved laterally to different positions, allowing for multiple sampling operations at different locations on its surface, thereby expanding the sampling range. After the refractory brick is clamped and fixed, personnel can control the fourth hydraulic rod 17 according to the required sampling location. The extension and retraction of the fourth hydraulic rod 17 can drive the slide 10 to move back and forth relative to the support plate 7. By cooperating with the clamping plate 3, it is possible to sample different locations on the refractory brick, improving the overall usage effect. After the slide 10 moves to the designated position, the push out of the second hydraulic rod 9 can drive the entire support plate 7 to move down along the slide rod 6, causing the cutting teeth 21 at the bottom of the sampling cylinder 20 to contact the surface of the refractory brick. The rotation of motor 15 drives drive gear 16 to rotate, which in turn drives transmission gear 14 to rotate, thereby causing sampling cylinder 20 to rotate at high speed. At this time, the cutting teeth 21 at its bottom can perform rotary cutting on the surface of the refractory brick. As the second hydraulic rod 9 continuously pushes out, it drives sampling cylinder 20 to continuously extend into the refractory brick, thus achieving sampling. After sampling is completed, the second hydraulic rod 9 resets, allowing sampling cylinder 20 to detach from the refractory brick. Then, the third hydraulic rod... The extension of the pressure rod 11 can drive the connecting plate 12 to apply pressure to the push rod 18, thereby causing the push rod 18 to move downward to push the top plate 19. At this time, the top plate 19 can push out the refractory brick sample inside the sampling cylinder 20, so that the personnel can obtain the complete refractory brick sample, which is convenient for subsequent testing operations. The entire sampling process does not require a large number of personnel to participate, which can effectively reduce the labor intensity of personnel, while ensuring the safety of operation and making it easier to use. The device as a whole has the advantages of labor-saving sampling, sample core ejection, and wide sampling range.
