Slope trimming attachment and working machine

A slope trimming attachment, comprising:

• a base, a first cutting device, a leveling mechanism, and a turning mechanism;
• wherein the first cutting device and the leveling mechanism are arranged on the turning mechanism;
• the turning mechanism is rotatably arranged on the base, and the turning mechanism is configured to be able to adjust an angle of a cutting surface of the first cutting device relative to the slope surface and an angle of a leveling surface of the leveling mechanism relative to the slope surface through rotation;
• wherein the turning mechanism is arranged on at least one of two ends of the base in a first direction;
• the turning mechanism is rotatable relative to the base along an axis in a second direction;
• wherein the first direction is along a length direction of the base, and the second direction is along a width direction of the base;
• wherein the turning mechanism comprises a turning plate assembly and a drive assembly;
• wherein the turning plate assembly comprises a turning plate and a connecting plate;
• one end of the connecting plate is rotatably connected to the base, and the other end of the connecting plate is rotatably connected to one end of the turning plate;
• the first cutting device and the leveling mechanism are installed on the turning plate;
• the drive assembly is connected between the base and the turning plate;
• and
• wherein the drive assembly is configured to adjust an angular position of the connecting plate relative to the base and an angular position of the turning plate relative to the connecting plate.
