Frozen soil trench excavating cutter provided with hobs
The invention provides a frozen soil trench excavating cutter provided with hobs. The frozen soil trench excavating cutter can improve the excavating efficiency. The cutter comprises a cutter body, a protection shell and a center residue collecting bucket. The disc-shaped hobs are arranged on the cutter body in the periphery radial direction and are divided into four areas on the cutter body. The front end and the rear end of each area are provided with a residue scrapping plate and a residue inlet. Residue sliding plates are used for conveying residue soil to the center residue collecting bucket, and the disc-shaped hobs in each area are arranged in a V shape. According to the frozen soil trench excavating cutter, the TBM excavating technology and the cutter design technology in a low-temperature environment are fully combined, the excavating efficiency of a frozen soil trench at the temperature ranging from -40 DEG C to 0 DEG C is improved, and due to the fact that the disc-shaped hobs in each area are arranged in the V shape, flowing of the residue soil is facilitated.
