Through the test assembly arranged on the base 1, the weighing plate 8 is pressed to drive the outer blocking rod 9 to move on one side of the vertical plate 2 through the guidance of the slider 10, and the hydraulic rod 12 is pulled to extend. The tension extending from the output end of the hydraulic rod 12 detects the weight of the rock and soil. At the same time, when the weighing plate 8 is displaced, the pull rope 5 can be stretched. When the pull rope 5 is stretched, the reinforcing rod 6 and the weight 7 are displaced. By adding the weight 7 to the reinforcing rod 6, the rock and soil on the weighing plate 8 can be weighed again. It is easy to ensure the accuracy of the device when weighing the rock and soil, and the specific structure of the assembly is set as follows;

[0025] The test assembly includes a vertical plate 2 arranged on the top of the base 1 for support, a support rod 3 for lifting is arranged on the top of the vertical plate 2, pulleys 4 are arranged at both ends of the support rod 3, and a pull rope 5 is arranged on the pulley 4;
