Damage detection device for screen cloth of vibrating screen

The utility model discloses a damage detection device for a screen mesh of a vibrating screen, a material collecting screen mesh is arranged at a discharge port of the vibrating screen through an elastic piece in a supporting manner, and the aperture of the material collecting screen mesh is one numerical value larger than that of an upper-layer screen mesh. In the discharging process of the vibrating screen, if the screen mesh is damaged, large materials can fall, materials with the diameter larger than the aperture of the upper layer are collected into the material collecting screen mesh, when the large materials are collected to a certain amount, the elastic piece can be driven to press downwards, and whether the screen mesh is damaged or not is judged by observing the height position of the material collecting screen mesh or the deformation degree of the elastic piece. 本实用新型公开了一种振动筛筛网破损检测装置，在振动筛出料口通过弹性件支撑设置有集料筛网，集料筛网的孔径大于上层筛孔一个数值。在振动筛出料过程中，若筛网破损，则会造成大物料下落，物料大于上一层孔径的物料被收集至集料筛网内，当大物料收集到一定量时，会带动弹性件下压，通过观察集料筛
