The embodiments of this utility model will be described below based on its overall structure.

[0023] Reference Figure 1 In this embodiment of the present invention, a sampling drill bit for quality testing and identification of construction projects includes: a drilling rig assembly 1, a sliding connection assembly 2 fixedly disposed on one side of the drilling rig assembly 1, an adjustment frame assembly 3 slidably disposed on the outside of the sliding connection assembly 2, a support adjustment beam assembly 4 installed on one upper end of the adjustment frame assembly 3, and support foot assemblies 5 rotatably connected to both sides of the support adjustment beam assembly 4.

[0024] Reference Figure 2 The drilling rig assembly 1 includes a sampling drilling rig body 10. A body screw 11 is fixedly installed in the middle of one side of the sampling drilling rig body 10. Limiting rods 12 are fixedly installed around one side of the sampling drilling rig body 10. A sampling drilling rig handle 13 is fixedly installed on the other side of the sampling drilling rig body 10. A drilling rig drive motor 14 is fixedly installed at one end of the upper part of the sampling drilling rig body 10. A sampling drilling rig shaft 15 is rotatably connected to one end of the lower part of the sampling drilling rig body 10. A sampling drill bit 16 is fixedly installed at one end of the lower part of the sampling drilling rig shaft 15.

[0025] Reference Figure 3 The sliding connection assembly 2 includes a sliding mounting base 20, with a sliding screw through hole 21 in the middle of the sliding mounting base 20, and limit through holes 22 in the four sides of the sliding mounting base 20. Sliding connecting bases 23 are fixedly provided at both ends of the outer side of the sliding mounting base 20, and sliding connecting through holes 24 are provided inside the sliding connecting base 23.

[0026] Reference Figure 4The adjusting frame assembly 3 includes an adjusting frame body 30. A semi-circular adapter 31 is fixedly installed at the upper center of the adjusting frame body 30. An angle reference scale 32 is provided on the outer side of one end of the semi-circular adapter 31. A rotating adjusting screw 33 is fixedly installed at the middle of one end of the semi-circular adapter 31. Sliding limit rods 34 are fixedly installed at both ends of the inner side of the adjusting frame body 30. A short buffer elastic element 35 is sleeved on the upper outer side of the sliding limit rod 34. A long buffer elastic element 36 is sleeved on the lower outer side of the sliding limit rod 34. The sliding limit rod 34 is adapted to slide into the sliding through hole 24. The short buffer elastic element 35 and the long buffer elastic element 36 are respectively located on the upper and lower sides of the sliding connection seat 23.

[0027] The above scheme involves rotating the drilling rig assembly 1, sliding connection assembly 2, and adjusting frame assembly 3 around the rotating adjusting screw 33 to a suitable angle. After locking with a fixing nut, the sampling drill bit can be moved downwards by holding the sampling drill handle 13 through the sliding connection assembly 2 within the adjusting frame assembly 3 for drilling and sampling. By setting the sliding connection assembly 2 and adjusting frame assembly 3, the drilling is more stable when moving downwards, which is more stable than the traditional manual holding. The long buffer elastic element 36 can provide a certain buffering effect when the drilling rig assembly 1 is pressed down to drill, and when the drilling rig assembly 1 is moved upwards, the long buffer elastic element 36 rebounds, making it easier to lift the drilling rig assembly 1. The short buffer elastic element 35 at the top can prevent the drilling rig assembly 1 from hitting the top of the adjusting frame assembly 3 too quickly when it is lifted, providing a certain buffering effect. The sampling drill bit drill with this structure is more convenient and easy to use.

[0028] Reference Figure 5 The support adjustment beam assembly 4 includes a support adjustment crossbeam 40. An indicator arrow 41 is fixedly installed at the upper center of the support adjustment crossbeam 40. A rotation adjustment through hole 42 is opened in the middle of the support adjustment crossbeam 40. A transition limit plate 43 is fixedly installed on both sides of the support adjustment crossbeam 40. A support foot transition screw 44 is fixedly installed at the middle of one end of the transition limit plate 43. The indicator arrow 41 is adapted to the angle reference scale 32. The rotation adjustment through hole 42 is adapted to the rotation adjustment screw 33.

[0029] Reference Figure 6 The support foot assembly 5 includes a support foot adapter 50. The support foot adapter 50 has an adapter through hole 51 in the middle. A support foot long rod 52 is fixedly installed at one end of the outer side of the support foot adapter 50. A support pointed foot 53 is screwed to one end of the support foot long rod 52. The adapter through hole 51 is adapted to the support foot adapter screw 44.

[0030] The above solution is adopted: after rotating and adjusting the four sets of support leg components 5 to a suitable angle, the fixing bolts are tightened to fix them and place them on the working ground. The support pointed feet 53 are screwed onto the support leg long rods 52, which can firmly position and support the entire device, and can be easily disassembled and replaced later.

[0031] The working principle of this utility model is as follows: First, depending on different usage needs, rotate and adjust the four sets of support foot assemblies 5 to a suitable angle, then tighten the fixing bolts to secure them and place them on the working ground. The support pointed feet 53, screwed onto the support foot long rods 52, firmly position and support the entire device, and allow for easy disassembly and replacement later. Next, rotate the drilling rig assembly 1, sliding connection assembly 2, and adjusting frame assembly 3 around the rotating adjusting screw 33 to a suitable angle, then lock them with the fixing nuts. Finally, the sampling drilling rig handle 13 can be held by the sliding connection assembly 2, which is located on the adjusting frame assembly 3. The inner sliding joint moves downward to drill and sample. By setting the sliding connection component 2 and the adjusting frame component 3, the drilling is more stable when moving downward, which is more stable than the traditional manual handling. The long buffer elastic element 36 can provide a certain buffering effect when the drilling machine component 1 is pressed down to drill. When the drilling machine component 1 is moved upward, the long buffer elastic element 36 rebounds, making it easier to lift the drilling machine component 1. The short buffer elastic element 35 set above can prevent the drilling machine component 1 from hitting the top of the adjusting frame component 3 too quickly when it is lifted, which can also provide a certain buffering effect. The sampling drill bit drill with this structure is more convenient and easy to use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
