Particle crushing device based on three-dimensional multi-axis loading

The invention provides a particle crushing device based on three-dimensional multi-axis loading, and belongs to the technical field of rock-soil particle crushing test.The particle crushing device comprises an annular track support system, a loading control system and an image acquisition system, the loading control system is connected with the annular track support system, and the annular track support system is used for controlling the loading control system to rotate; and the image acquisition system is arranged on the outer side of the annular track bracket system and is used for recording a particle crushing image. The annular track support is composed of a plurality of concentric rings, and the structural design can achieve two dimensions and three dimensions; according to the invention, the detachable loading device is fixed on the annular track bracket through the annular slide block, so that the multi-axis and multi-direction loading requirement of the rock-soil particle material is realized.
