The lower end of the support frame is inserted into the silo from the top, and the upper end is located outside the silo. The lifting device is located at the top of the silo, and its upper end is connected to the top of the support frame, and can drive the support frame to move up and down. The lower end of the support frame is fixedly connected to the support shaft that spans the internal space of the silo. The sludge breaking device includes a first sludge breaking roller, which is mounted on the support shaft and can rotate about the support shaft. The surface of the first sludge breaking roller is provided with a plurality of first conical cutting teeth.

[0006] As an improvement, the mud-breaking device further includes a second mud-breaking roller, which is mounted on a support shaft and can rotate around the support shaft. The surface of the second mud-breaking roller is provided with a number of second conical cutting teeth. The first mud-breaking roller is installed in the middle section of the support shaft, and two second mud-breaking rollers are provided, which are respectively installed on both sides of the first mud-breaking roller.
