Embodiment Construction
[0022] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] Depend on Figure 1 to Figure 14 Given, including a rectangular shell 1, the inner lower side wall of the rectangular shell 1 is provided with a through groove 2 which is vertically axial and vertically penetrated, and the inner upper side wall of the rectangular shell 1 is rotatably connected with a sleeve 3 coaxial with the through groove 2 The sleeve 3 is coaxially slidably connected with a telescopic tube 4 whose lower end protrudes from the sleeve 3. The lower end of the telescopic tube 4 can protrude from the through groove 2 and is coaxially provided with a drill core 5 with the opening facing downward. The inside of the sleeve 3 is the same The shaft is provided with a stamping column 6 that can be inserted into the core barrel 5, and the rectangular shell 1 is provided with a lifting block 7 that can move...

The invention discloses a highway detection sampling device, and effectively solves the problem of inconvenience in operation during highway sampling. The device comprises a rectangular shell, a through groove is formed in the lower side wall in the rectangular shell, a sleeve coaxial with the through groove is rotationally connected to the upper side wall in the rectangular shell, a telescopic pipe is slidably connected into the sleeve, a core drilling barrel with a downward opening is arranged at the lower end of the telescopic pipe, a tamping column is arranged in the sleeve, a lifting block is arranged in the rectangular shell, and a sliding groove with a forward opening is formed in the front side of the lifting block; a U-shaped block is arranged in the sliding groove, a rotating shaft is rotationally connected into the rectangular shell, vertical grooves with leftward openings are formed in the upper side and the lower side of the rotating shaft correspondingly, the two vertical grooves communicate through an inclined groove, clamping columns capable of being inserted into the vertical grooves are arranged on the left side of the U-shaped block, a disc is arranged at the right end of the lower side of the rotating shaft, a vertically axial storage block is rotationally connected to the upper end of the disc and storage groove is arranged in the storage block; a spiral groove is formed in the storage block, and an insertion column capable of being inserted into the spiral groove is arranged on the right side of the U-shaped block; and the structure is simple, the conception is novel, the use is convenient, and the usability is strong.
Description
technical field [0001] The invention relates to the technical field of road construction equipment, in particular to a road detection and sampling device. Background technique [0002] At present, when testing the degree of compaction and the thickness of the structural layer on asphalt pavement, pavement core sampling machines are generally used to take out core samples of the structural layer for testing. The rotating coring barrel grinds the asphalt pavement structure layer to drill core samples. The main principle is to use the core barrel drill bit to rotate at high speed to continuously cut the pavement structure, and form a cylindrical core sample of the pavement structure in the barrel that is basically the same diameter as the barrel. [0003] However, during the operation, due to the continuous friction and rotation between the drill bit and the pavement structure, sand-like fine materials are continuously filled into the core sample and the inner wall of the drill...
