摘要： The invention provides an engineering vehicle having a ballast unloading device (100) and a ballast leveling device (200). The engineering vehicle includes a vehicle body (10), and the ballast unloading device (100) and the ballast leveling device (200) arranged on the vehicle body (10). The ballast unloading device (100) includes: a ballast carrying portion (20) provided with ballast unloading openings (21), and the ballast carrying portion (20) being arranged on the vehicle body (10); ballast unloading doors (30) capable of rotating relative to the ballast carrying portion (20), inner unloading passages (31) and outer unloading passages (32) being arranged on the ballast unloading doors (30), the ballast unloading doors (30) further including stop portions (33) located between the inner unloading passages (31) and the outer unloading passages (32). The ballast leveling device (200) includes: a plough piece (220) slidably fixed to the vehicle body (10) so as to ascend or descend relative to the vehicle body (10), and a plough head (224) used for leveling ballasts being arranged on the plough piece (220); a first crank (230) rotationally fixed to the vehicle body (10); a connecting rod (240), with one end being rotationally connected with the first crank (230), and the other end being rotationally connected with the plough piece (220); and a driving part (250) used for driving the first crank (230) to rotate.
