Description

Technical Field

[0001] This utility model relates to the field of sampling equipment technology, specifically a sampling device for road surface testing in highway engineering. Background Technology

[0002] Sampling equipment for highway pavement testing is an important auxiliary device in the highway construction, maintenance, and quality supervision processes. Its purpose is to provide physical samples of the pavement that meet testing standards for professional analysis.

[0003] Utility model patent CN220670986U discloses a road surface inspection sampler, including a support plate. A drilling sampling mechanism is provided on the upper surface of the support plate. An mounting plate is fixedly installed on one side of the base plate, and a stabilizing column is fixedly installed at the bottom of the mounting plate. A positioning nail is fixedly installed at the bottom of the stabilizing column, and an auxiliary positioning component is provided inside the stabilizing column. This utility model features a design with two sets of inclined surfaces fitting together. When placing the drilling rig, the reduction motor is activated according to the ground's inclination angle. Subsequently, the top plate moves, and the other set of inclined surfaces on the adjusting plate is compressed and moves downwards. The adjusting plate then moves the base plate away from the support plate, allowing the base plate to fit against the ground. This ensures the support plate is stably placed in the sampling area, eliminating the need for repeated adjustments with multiple bolts. This achieves the advantages of convenient and quick placement of the drilling sampling mechanism, improving work efficiency.

[0004] In the aforementioned existing technologies, it is inconvenient to provide protection during the drilling and sampling process, and the dust generated when drilling into the ground will spill out in large quantities, causing pollution to the working environment. Therefore, improvements are needed. Utility Model Content

[0019] Please see Figure 1 , Figure 2 , Figure 3 The protective mechanism 8 includes a protective cover 81. Two protective covers 81 are symmetrically distributed on the outside of the drill bit 7. The two protective covers 81 are in contact with each other. A connecting rod 82 is fixedly connected to the outside of the protective cover 81. A connecting block 83 is fixedly sleeved on the outside of the connecting rod 82. A connecting sleeve 84 is slidably sleeved on the outside of the connecting block 83. The connecting sleeve 84 is fixedly connected to the connecting plate 5. A fixing rod 85 is fixedly connected to the top of the inner wall of the connecting sleeve 84. The fixing rod 85 is slidably connected to the connecting rod 82. A first spring 86 is provided on the outside of the fixing rod 85.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting mechanism 9 includes a support block 91. The lower end of the connecting block 83 contacts two symmetrically distributed support blocks 91. The support blocks 91 are slidably connected to the connecting sleeve 84 and to the connecting seat 92.

[0021] The specific implementation process of this utility model is as follows: In use, the equipment is first moved to the sampling location, and then the hydraulic cylinder 4 is started. The output end of the hydraulic cylinder 4 drives the connecting plate 5 to move down, and the connecting plate 5 drives the motor 6 to move down. At the same time, the motor 6 drives the drill bit 7 to rotate. When the connecting plate 5 moves down, it also drives the connecting sleeve 84 to move down. The connecting sleeve 84 drives the connecting rod 82 and the protective cover 81 to move down. The protective cover 81 will first contact the ground and stop moving. The connecting plate 5 continues to move down, and the connecting plate 5 drives the connecting sleeve 84 and the fixing rod 85 to move down. The fixing rod 85 will move down along the connecting rod 82. The connecting sleeve 84 will press down the first spring 86. Under the elastic action of the first spring 86, it will give the connecting rod 82 a downward pressure, which can keep the protective cover 81 in contact with the ground. When the connecting plate 5 moves down, it will cause the drill bit 7 to move down. By contacting the ground with the drill bit 7, a hole can be drilled to sample the ground. Under the action of the protective cover 81, the outside of the drill bit 7 can be protected to prevent the spread of smoke and dust during the drilling and sampling process from causing pollution to the external environment.

[0022] When it is necessary to disassemble the protective cover 81, simply pull the slide rod 93 horizontally. The slide rod 93 will drive the support block 91 to move horizontally. The support block 91 will compress the second spring 95. At the same time, the support block 91 will drive the magnetic block 96 to move horizontally. When the magnetic block 96 is attracted to the magnet 97, it will cause the support block 91 to separate from the connecting block 83. Then the connecting block 83 and the connecting rod 82 can be removed from the inside of the connecting sleeve 84, and the protective cover 81 can be disassembled, which facilitates the inspection and maintenance of the drill bit 7.
