The gravel will be blocked by the protective shell 701, avoiding the gravel from splashing out and injuring people. When the drilling component 6 is working, it will synchronously drive the main pulley 707 to rotate, and the main pulley 707 drives the secondary pulley 705 to rotate through the transmission belt 706. The secondary pulley 705 drives the fan blade 704 to rotate through the transmission shaft, and the dust in the protective shell 701 is sucked into the dust collection box 702, and the dust is filtered by the filter 703 in the dust collection box 702, and finally the gas with the dust particles filtered out is discharged, so as to avoid a large amount of dust during drilling to pollute the environment or be inhaled by the human body to affect health.

[0024] In this embodiment, Figure 3 As shown, the protective shell 701 is divided into a fixed shell and a movable shell. The fixed shell is hollow in design, and the movable shell can be slidably stored in the cavity of the fixed shell; when the hydraulic rod 4 pushes the mounting plate 5 downward, the protective shell 701 also moves downward. At this time, the movable shell will first contact the ground, and then the mounting plate 5 will continue to push the drilling assembly 6 downward for drilling sampling. At this time, the movable shell will gradually shrink into the fixed shell, so that during the entire drilling sampling process, the protective shell 701 can cover the drilling assembly 6 inside to play a protective role.
[0025] In this embodiment, Figure 4As shown, the drilling assembly 6 includes a motor 601 fixedly connected to the middle of the top surface of the mounting plate 5, the output end of the motor 601 is fixedly connected to an auger 602, the outer side of the bottom end of the auger 602 is in contact with the inner wall of the collecting tank 603, and the top surface of the collecting tank 603 is fixedly connected to two movable rods 604, both of which are slidably connected to the middle of the fixed cylinder 605, the top of the fixed cylinder 605 is connected to the bottom surface of the mounting plate 5, a drill bit is provided at the bottom end of the auger 602, and the main pulley 707 is fixedly connected to the top of the auger 602; when When the motor 601 drives the auger 602 to rotate, and under the action of the hydraulic rod 4, the auger 602 and the collecting tank 603 move downward synchronously.

At this time, the auger 602 continues to move downward and drill into the concrete. Because the auger 602 fits the inner wall of the collecting tank 603, the auger 602 can transport the drilled concrete sample upward, and after transporting it to the top of the collecting tank 603, it scatters around, and finally the concrete sample falls into the collecting tank 603 to complete the sample collection.
[0026] The use method and advantages of the utility model: When the concrete drilling sampling device is used, the working process is as follows:
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the motor 601 is started to drive the drilling assembly 6 to rotate, and then the hydraulic rod 4 pushes the drilling assembly 6 downward through the mounting plate 5, so that the drilling assembly 6 gradually drills into the concrete, and the concrete fragments are transported upward through the auger 602 and finally fall into the collecting trough 603, thereby completing the sampling of the concrete.
