Two test slots 20 for placing rocks are symmetrically opened on the wall of the load-bearing body 11. A motor is fixed on the side wall of the main body 10 to drive the load-bearing body 11 to rotate and discharge the tested rocks from the test slot 20. The main body 10 is a rectangular frame structure. The support legs are fixedly installed on the outer wall of the main body 10. The load-bearing body 11 is located inside the opening of the main body 10.

The test slot 20 is a rectangular slot, and the test slot 20 is the same length as the load-bearing body 11. By placing a rock into the test slot 20, after the test is completed, the load-bearing body 11 is driven by a motor to rotate, so that the rock rotates to a downward position along with the load-bearing body 11, and the tested rock is discharged. The other test slot 20 on the wall of the load-bearing body 11 is turned upward, and another rock block can be placed in the upward test slot 20, which is convenient for continuous testing, high efficiency, and convenient discharge.
