It is necessary to communicate natural cracks through volume transformation to form a complex crack network to increase production capacity. Therefore, it is necessary to add materials into the cracks. In the prior art, when the traditional feeding equipment is in use, a filter screen is set inside it to filter the material to make the size of the material uniform. However, different types of materials and particle sizes are required for different cracks. This leads to the need to replace different filter screens when adding materials to different cracks. The filter screen needs to be replaced every time the material is added. The process is very cumbersome and seriously affects work efficiency.
