Then, the soil in the drill rod is sub-packed into different sub-packaging storage bottles. However, the existing sampling equipment is not easy to remove the soil from the drill rod after sampling, and the soil is likely to remain in the drill rod. Therefore, a sampling device for engineering quality inspection that can be sub-packed is proposed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The embodiments of the present utility model provide a sampling device for engineering quality inspection that can be sub-packaged, such as Figure 1-6As shown in the figure, it includes a notched air supply ring 1. A notched plugging ring 2 is arranged below the notched air supply ring 1. The bottom surface of the notched air supply ring 1 is open. An air pump is installed on the upper surface of the notched air supply ring 1, which can fill gas into the notched air supply ring 1. A notched installation ring 7 is arranged below the notched plugging ring 2. Power telescopic rods A3 are fixedly connected to the left and right side surfaces of the notched installation ring 7. The upper ends of the power telescopic rods A3 are fixedly connected to the notched air supply ring 1. A vertical shaft 6 is fixedly penetrated through the upper surface of the notched air supply ring 1. The vertical shaft 6 is located on the inner ring side of the notched plugging ring 2. The notched plugging ring 2 is rotatably sleeved on the outer surface of the vertical shaft 6. An activity block 8 is arranged at the notch of the notched installation ring 7. The notches of the notched plugging ring 2, the notched installation ring 7, and the notched air supply ring 1 are of equal size. The front end of the activity block 8 is adapted to the notch of the notched plugging ring 2. The power telescopic rod A3 can change the distance between the notched installation ring 7 and the notched air supply ring 1. One end of the activity block 8 is slidably sleeved on the outer surface of the vertical shaft 6.

[0025] A power telescopic rod B4 is fixedly inserted at the front end of the activity block 8 and in front of the notched plugging ring 2. The upper and lower ends of the power telescopic rod A3 are bent, providing a rotation space for the rotation of the power telescopic rod B4, the activity block 8, and the notched plugging ring 2, so that the power telescopic rod B4 will not interfere with the power telescopic rod A3 when rotating around the vertical shaft 6. The upper end of the power telescopic rod B4 is fixedly connected to the notched plugging ring 2. The power telescopic rod B4 can change the distance between the activity block 8 and the notched plugging ring 2. When the activity block 8 moves to the highest position, the upper surface of the activity block 8 is flush with the upper surface of the notched plugging ring 2 and the bottom surface of the notched air supply ring 1. A sampling cylinder 9 is rotatably penetrated through the upper surface of the activity block 8. The sampling cylinder 9 can drill into the soil when rotating and moving downward. The soil sample enters the sampling cylinder 9. A soil pushing pad 11 is slidably inserted into the sampling cylinder 9. The upper surface of the soil pushing pad 11 is elastically connected to the inner top wall of the sampling cylinder 9 through a tension spring 12. A power structure 5 is installed on the upper surface of the activity block 8 and behind the sampling cylinder 9. The sampling cylinder 9 is connected to the power structure 5. A plurality of detachable sub-packaging tubes 10 are installed on the bottom surface of the notched installation ring 7. The upper surface of the sub-packaging tube 10 is flush with the upper surface of the notched installation ring 7. The upper surface of the sampling cylinder 9 is flush with the upper surface of the activity block 8. The height of the activity block 8 at the notch of the notched installation ring 7 is equal to the height of the notched plugging ring 2.

[0026] The power structure 5 includes a double-headed motor 51, a gear A 52, and a gear B 53. The gear B 53 is fixedly sleeved on the outer surface of the sampling cylinder 9. The gear A 52 meshes with the rear of the gear B 53. The gear A 52 is fixedly connected to the output end of the double-headed motor 51. The movable block 8 is fixedly sleeved on the outer surface of the double-headed motor 51. A dial plate 511 is arranged above the double-headed motor 51. The dial plate 511 is fixedly connected to the output end of the double-headed motor 51. A disc 512 is fixedly sleeved on the outer surface of the vertical shaft 6. A plurality of uniformly distributed hard plates 514 are fixedly connected to the bottom surface of the disc 512. When the power expansion rod B 4 drives the dial plate 511 to move to the same plane as the hard plate 514, when the dial plate 511 contacts the hard plate 514, the dial plate 511 drives the movable block 8 and the notch blocking ring 2 to rotate synchronously under the block of the hard plate 514. A plurality of grooves 515 are formed on the circumferential side surface of the disc 512. The number of the grooves 515 is equal to the sum of the number of the dispensing pipes 10 and the number of the sampling cylinders 9. The plurality of grooves 515 are equidistantly distributed on the outer surface of the disc 512. The plurality of dispensing pipes 10 and the sampling cylinders 9 are uniformly distributed in a circumferential array with the axis of the vertical shaft 6 as the center. The number of the hard plates 514 is equal to the number of the grooves 515. A triangular block 516 is arranged on one side of the disc 512. Another side surface of the triangular block 516 is fixedly connected to a pressure expansion rod 513. The other end of the pressure expansion rod 513 is fixedly connected to the notch blocking ring 2. When the notch blocking ring 2 rotates, the triangular block 516 moves on the surface of the groove 515, and the pressure expansion rod 513 expands and contracts synchronously. When the dial plate 511 contacts and then disengages from the hard plate 514, the triangular block 516 moves from one groove 515 to another adjacent groove 515, so that each time the notch blocking ring 2 rotates once, it drives the sampling cylinder 9 to move once and communicate with the next dispensing pipe 10. The notch blocking ring 2 rotates intermittently, increasing the time for the sampling cylinder 9 to push the soil into the dispensing pipe 10.

[0027] Working principle: When drilling and sampling are required, the power telescopic rod B4 first drives the dial 511 downward through the movable block 8 to disengage from the hard board 514. Then, the double-headed motor 51 is started, and the sampling cylinder 9 is driven to rotate through the meshing of gear A52 and gear B53. Next, the power telescopic rod A3 drives the notch mounting ring 7 to move upward to prevent the lower end of the dispensing tube 10 from contacting the ground. Then, the power telescopic rod B4 drives the sampling cylinder 9 to rotate downward and drill into the soil for sampling through the movable block 8. After sampling is completed, the double-headed motor 51 is stopped, and the power telescopic rod B4 drives the movable block 8 to move upward so that the upper surface of the sampling cylinder 9 is flush with the upper surface of the notch plugging ring 2. At this time, the dial 511 and the hard board 514 are in the same plane, and the power telescopic rod A3 controls the upper surface of the notch mounting ring 7 to be flush with the bottom surface of the sampling cylinder 9. The double-headed motor 51 is started to drive the dial 511 to rotate. After the dial 511 contacts the hard board 514, it pushes the notch plugging ring 2 to rotate. At the same time, the triangular block 516 is driven to slide in the groove 515 through the pressure telescopic rod 513. When the dial 511 contacts and disengages from the hard board 514, the triangular block 516 is driven to move to the next groove 515. At this time, the sampling cylinder 9 just communicates with the next dispensing tube 10, and the gas in the notch air supply ring 1 fills the sampling cylinder 9, applying a thrust to the earth-moving pad 11. When the sampling cylinder 9 communicates with the dispensing tube 10, the earth-moving pad 11 pushes the overall soil in the sampling cylinder 9 downward under the upper air pressure, and the soil is pushed into the corresponding dispensing tube 10. The dial 511 intermittently contacts the hard board 514 during rotation, pushing the notch plugging ring 2 and the sampling cylinder 9 to rotate intermittently, so that the sampling cylinder 9 intermittently moves to communicate with multiple dispensing tubes 10 in turn to complete the dispensing of the soil in the sampling cylinder 9.
