[0030] Move the gantry 1 to the area to be collected, use the clamping component 2 to clamp the upper surface of the building material to prevent the building material from shifting during the drilling sampling process, and energize the electric push rod 3 and the motor 51. The electric push rod 3 extends and drives the lifting plate 4, the sampling component 5, and the protective component 6 to move downward, so that the lower surface of the protective tube 61 is pressed against the surface of the building material to be collected. Close the electric push rod 3, and the motor 51 drives the drill rod 52 to rotate to drill and sample the building material. The sample falls into the protective tube 61 through the drill rod 52, and the sampling work of the building material is completed. At the same time, the protective tube 61 can effectively prevent the debris of the building material from splashing out during the drilling sampling process, thereby improving the safety of sampling.

[0031] like Figure 2 , Figure 3 As shown, the upper surface of the protective tube 61 is fixedly connected with an internal threaded tube 62, and the upper part of the inner wall of the internal threaded tube 62 is threadedly connected with a connecting sleeve 67, and the side of the top lower surface of the connecting sleeve 67 close to the fixing ring 63 overlaps with the upper surface of the bottom of the fixing ring 63, and the inner wall of the lifting plate 4 is threadedly connected with a reverse twin screw 65, and the front end of the reverse twin screw 65 extends to the front side of the lifting plate 4, and the front and rear sides of the outer surface of the reverse twin screw 65 are threadedly connected with a semicircular block 2 66 and a semicircular block 1 64 respectively, and the upper surfaces of the bottom of the semicircular block 1 64 and the semicircular block 2 66 close to the fixing ring 63 overlap with the front and rear positions of the top lower surface of the connecting sleeve 67 respectively.

[0034] The straight slot 41 is used to guide the semicircular block 1 64 and the semicircular block 2 66 , so that the semicircular block 2 66 and the semicircular block 1 64 move relatively along the reverse twin screws 65 .

[0037] like Figure 6-Figure 8As shown, a pressure plate 22 is fixedly installed at the lower end of the two adjusting screws 21, and a slider 25 is fixedly installed at the front and rear positions of the two pressure plates 22 on one side. Guide holes 26 are opened on the upper surfaces of the four sliders 25, and the inner walls of the four guide holes 26 are slidably connected to the outer surfaces of the four guide rods 23 respectively.

[0038] The guide rod 23 is used to guide the guide hole 26 on the slide block 25, so that the pressing plate 22 moves down to press the building material tightly, thereby preventing the building material from deviating during the drilling sampling process and affecting the drilling sampling effect.

[0041] The working principle of the present invention is as follows: the gantry 1 is moved to the area to be collected, the adjusting screw rod 21 is rotated respectively, the guide rod 23 is used to guide the guide hole 26 on the slider 25, so that the pressing plate 22 moves down to press the left and right sides of the building material, the electric push rod 3 and the motor 51 are energized, the electric push rod 3 is extended to drive the lifting plate 4, the sampling component 5, and the protective component 6 to move down, so that the lower surface of the protective tube 61 is pressed against the surface of the building material to be collected, the electric push rod 3 is closed, and the motor 51 is driven to rotate the drill rod 52 to drill and sample the building material, and the sample falls into the protective tube 61 through the drill rod 52.

[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
