The invention discloses excavating equipment. The excavating equipment comprises a rack, wherein the rack has the length extending from the front end to the rear end of the rack. The rack also has the directed width vertical to the length. A cantilever can be connected to the rear end of the rack in a pivoted way. A cutting part is arranged on the cantilever. A cover structure at least partially covers the cutting part. A vacuum source is communicated with a fluid inside the cover structure and is used for pumping and sucking air containing dust from the inside of the cover structure. A filter is used for filtering the air pumped and sucked from the inside of the cover structure through the vacuum source. A dust shield is downwards protruded from the cover structure and extends along at least one part of the periphery of the cover structure. The dust shield has a structure which is located in front of chips generated through the cutting part and provides a limitation that an inward air flow passing through the dust shield is gradually reduced along the downward extension of the dust shield from the cover structure.
