[0024] Please see Figure 1-7 This utility model provides a technical solution:

[0025] A gravity-type wharf caisson foundation compaction testing device includes a mounting frame 1, a first receiving shell 6, and a second receiving shell 10. Each mounting frame 1 has a pair of positioning mortises 2 on its lower side. An adjusting seat 3 is fixedly connected between the two mounting frames 1. A sliding seat 4 is fixedly connected to the upper side of each mounting frame 1. A reinforcing frame 5 is fixedly connected to the upper side of the mounting frame 1. An adjusting shaft 7 is fixedly connected to the upper side of the first receiving shell 6. The outer side of the adjusting shaft 7 is screwed to the adjusting seat 3. The upper side of the adjusting shaft 7 is fixedly connected to the main shaft of a drive motor 8. A sliding shell 9 is fixedly connected to the outer side of the drive motor 8. The left and right sides of the sliding shell 9 are slidably connected to the sliding seat 4. The lower side of the first storage shell 6 is spirally connected to the second storage shell 10. A set of cutting blades 11 is fixedly connected to the lower side of the second storage shell 10. The inner side of the second storage shell 10 is fixedly connected to the spiral blade 12. The spiral center of the spiral blade 12 is fixedly connected to the central shaft 13. The inner side of the second storage shell 10 is fixedly connected to the mounting block 14. The front side of the mounting block 14 is fixedly connected to the hydraulic plate 15. The lower side of the hydraulic plate 15 is fixedly connected to the sealing plate 16. The left side of the sealing plate 16 is fixedly connected to the limit bracket 17.

[0026] The mounting brackets 1 are all bent brackets, with curved surfaces on the opposing sides of both mounting brackets 1. The inner side of the adjusting seat 3 is provided with a threaded slot, and the outer side of the adjusting shaft 7 is provided with threaded protrusions. The adjusting shaft 7 can drive the first storage shell 6, the second storage shell 10, and the cutting blade 11 to rotate and move downward synchronously. The sliding seats 4 are located on the left and right sides of the adjusting seat 3, and the opposing sides of the two sliding seats 4 are provided with "T"-shaped sliding grooves. The left and right sides of the sliding shell 9 are provided with "T"-shaped sliding protrusions. The sliding shell 9 can restrict the drive motor 8, causing the main body of the drive motor 8 to move downward with the adjusting shaft 7. The reinforcing bracket 5 is "U"-shaped. The frame, the inner side of the reinforcing frame 5 and the sliding seat 4 are fixedly connected. The first storage shell 6 and the second storage shell 10 are both located between the two mounting frames 1. The cutting blades 11 are distributed in a circumferential direction. The cylindrical soil blocks can be cut at the sampling point by the cutting blades 11. The rear side of the sealing plate 16 is attached to the inner wall of the second storage shell 10. The lower side and the right side of the sealing plate 16 are attached to the spiral blades 12. The front side of the sealing plate 16 is attached to the central shaft 13. The left side of the limiting frame 17 is attached to the inner wall of the second storage shell 10. The soil blocks can be cut into soil samples by the spiral blades 12. The soil samples can be stored by the second storage shell 10.

[0027] Workflow: The device is equipped with a mobile power supply and an external controller. Before use, the mobile power supply should be fully charged. The external controller is electrically connected to the drive motor 8 and the hydraulic plate 15. Manual operation of the external controller can adjust the operating status of the drive motor 8 and the hydraulic plate 15. All of the above are existing technologies. When using the device, the operator holds the reinforcement frame 5 and inserts the positioning bracket 2 into the sampling base bed, ensuring that the mounting frame 1 is horizontally distributed and that the lower side of the mounting frame 1 is in contact with the base bed. Then, the hydraulic plate 15, which is fixed by the mounting block 14, is adjusted to retract upwards. The hydraulic plate 15 drives the sealing plate 16 to move upwards. The sealing plate 16 has a limit bracket 17 on its left side. The right side of the sealing plate 16 is fitted with the spiral blade 12, and the front side of the sealing plate 16 is fitted with the central shaft 13. Therefore, the sealing plate 16 can move stably up and down. Then, the drive motor 8 is started, which drives the adjusting shaft 7 to rotate. Since the adjusting seat 3 and the adjusting shaft 7 are spirally connected, the adjusting shaft 7 can move downward while rotating. The main shaft of the drive motor 8 is connected to the adjusting shaft 7, and the adjusting shaft 7 will drive the drive motor 8 to move downward. The sliding shell 9 on the outside of the drive motor 8 can slide up and down along the sliding grooves of the two sliding seats 4. The sliding shell 9 can restrict the drive motor 8, so that the main body of the drive motor 8 moves downward with the adjusting shaft 7, and ensure that the main body of the drive motor 8 does not move downward. When rotation occurs, the first receiving shell 6, the second receiving shell 10, and the cutting blade 11 will also rotate and move downward synchronously. The cutting blade 11 can cut the cylindrical soil block at the sampling point, and the spiral blade 12 can chop the soil block into soil samples. The second receiving shell 10 can store the soil samples. When the second receiving shell 10 is inserted into the subgrade to a certain depth, the drive motor 8 is turned off, and the hydraulic plate 15 is adjusted so that the hydraulic plate 15 extends downward, which resets the sealing plate 16 and seals the second receiving shell 10, preventing the soil samples from falling out. At this time, the worker can pull out the device to complete the sampling. The hydraulic plate 15 is then retracted upward to close the second receiving shell. The soil sample in the first housing shell 6 is poured into a designated container. The second housing shell 10 is then rotated off the first housing shell 6 to remove the soil sample adhering to the internal components of the second housing shell 10. The device can rotate and lower the first housing shell 6 and the second housing shell 10 through the adjusting seat 3 and the rotatable adjusting shaft 7. Soil is removed by the cutting blade 11 and the spiral blade 12. The second housing shell 10 is sealed by the movable sealing plate 16 to prevent the soil sample from falling out. This device does not require manual excavation of the soil sample and can quickly excavate the soil sample and remove it from the trench in the foundation bed. It can also conveniently put the soil sample into the designated container. This method is more time-saving and labor-saving.
