technical field

The utility model relates to the technical field of engineering machinery, in particular to a bucket used for excavating a trapezoidal trench.

Background technique

During the road construction process, it is often necessary to dig side ditches on both sides of the road. The side ditches are used to collect and remove precipitation from the road surface, road shoulders and slopes. The part is one of the slope drainage facilities and an indispensable part of the road drainage system. In order to prevent the accumulated water in the side ditch from infiltrating below the road surface and causing erosion to the subgrade, the side ditch is usually an inverted trapezoidal structure. In the prior art, the excavation of the inverted trapezoidal side ditch is usually firstly excavated by ordinary excavator buckets. The slopes on both sides of the ditches and straight ditches are then artificially trimmed and compacted, and trapezoidal buckets that can be excavated in one piece are also used. However, the trapezoidal buckets in the prior art often cannot adjust the angle of the hypotenuse, so the applicability is relatively low. Difference.
