The pressure bearing assembly 10 is used to place the soil sample to be tested, and the pressure applying assembly 20 is used to apply pressure to the soil sample. After the test is completed, the pressure bearing assembly 10 can clean up the waste of the soil sample, and the collecting assembly 30 can be used to collect the waste.

[0022] In this embodiment, the pressure-bearing assembly 10 may include a pressure-bearing platform 11, a base 12, two groups of support seats 13, a screw rod 14, a slider 15, at least one group of adjustment arms 16, a motor 17, a second hydraulic cylinder 18, and a scraper 19. A detection support plate 110 is embedded in the bottom of the pressure-bearing platform 11, and a connecting seat 111 is installed at the bottom of the pressure-bearing platform 11. A pressure sensor is installed below the detection support plate 110, so that the pressure applied can be detected by the pressure sensor after the soil sample is placed on the detection support plate 110 and squeezed by force. The right end of the bottom of the pressure-bearing platform 11 is hinged to the base 12, so that the pressure-bearing platform 11 can deflect with the connection between it and the base 12 as the rotation center. The two groups of support seats 13 are respectively installed and fixed on the opposite sides of the base 12, the screw rod 14 is rotatably supported between the two groups of support seats 13, and the motor 17 is installed and fixed on the adjacent support seats 13, and the output end of the motor 17 drives the adjacent end of the screw rod 14, so that the motor 17 can drive the screw rod 14 to rotate. The slider 15 is sleeved on the outer side of the screw rod 14 and is threadedly connected thereto. The two ends of at least one set of adjusting arms 16 (two sets in the figure) are respectively rotatably connected to the side wall of the slider 15 and the connecting seat 111 installed at the bottom of the pressure platform 11, so that the slider 15 can only move along the axial direction of the screw rod 14 through the threaded cooperation between the slider 15 and the screw rod 14, and the adjustment arm 16 limits the slider 15, and when it moves, the adjustment arm 16 can be used to push the pressure platform 11 to deflect, thereby adjusting the support angle of the pressure platform 11. The second hydraulic cylinder 18 is installed and fixed on the left side of the pressure platform 11, and the output end of the second hydraulic cylinder 18 extends into the inner cavity of the pressure platform 11 and is clamped and connected to the middle of the scraper 19. The bottom of the scraper 19 contacts the top of the detection support plate 110, and the right end of the scraper 19 is set to a cone, so that the scraper 19 can be driven by the output end of the second hydraulic cylinder 18 to push and clean the soil sample waste on the detection support plate 110 from above.

The first hydraulic cylinder 22 is mounted and fixed on the top of the enclosure cover 21, and the pressure block 23 is mounted and fixed on the output end of the first hydraulic cylinder 22, so that the first hydraulic cylinder 22 can drive the pressure block 23 to move above the pressure assembly 10. During the pressure test, the pressure block 23 is driven to move downward and apply pressure to the soil sample; when the test is completed, the pressure block 23 is driven to move upward to be above the scraper 19.
