[0024] In the embodiment, the bottom plate 1 and the top plate 2 are both circular flat structures, the support columns 3 are multiple and uniformly arranged on the outer side of the disc 4 in the circumferential direction, and the measuring assembly 6 is installed on one of the support columns 3.

[0025] As a preferred embodiment, the measuring assembly 6 comprises a sliding block 61, a mounting plate 62 and a protractor 63. The sliding block 61 is slidably arranged on the support column 3 along the length direction of the support column 3, the mounting plate 62 is fixedly installed on the sliding block 61, and the protractor 63 is a semicircular structure with the central axis of the disc 4 located in the plane of the disc surface of the protractor 63. The center of the protractor 63 is rotatably connected with the mounting plate 62. When measuring the rest angle, the sliding block 61 is slid relative to the support column 3, and the protractor 63 is rotated relative to the mounting plate 62, so that the straight edge on the protractor 63 is abutted on the generatrix of the calcium carbonate conical structure. At this time, the rest angle can be obtained through the inclination angle of the protractor 63.

[0026] Further, the sliding block 61 is sleeved on the support column 3, and the sliding mode of the sliding block 61 relative to the support column 3 can be manually adjusted by hand or automatically adjusted by electricity. For example, a pneumatic cylinder can be installed on the support column 3, and the sliding block 61 is installed on the extension end of the pneumatic cylinder, so that the sliding block 61 is driven to slide by the pneumatic cylinder. Alternatively, a screw rod transmission mechanism can be used to drive the sliding block 61 to slide on the support column 3, and the specific implementation is not limited here.
