The invention discloses a dye barrel with automatic pouring function for chemical engineering. The dye barrel comprises a base, the two ends of the top of the base are provided with hydraulic cylinders, the output ends of the hydraulic cylinders are provided with a mounting plate through piston push rods, the two ends of the top of the mounting plate are provided with first fixing rods, the portions, on one sides of the first fixing rods, of the top of the mounting plate are provided with second fixing rods, connecting rods are arranged between a barrel body and the first fixing rods through first bearings, a fixing ring is arranged at the bottom end of the surface of the barrel body, a motor is installed at the top end of the surface of each second fixing rod, the output ends of the motors are connected with second bearings through rolling screw rods, rolling nuts are installed on the rolling screw rods, and a connecting rope arranged between the rolling nuts penetrate through the fixing ring. According to the dye barrel, the hydraulic cylinders, the motors, the rolling screw rods, the rolling nuts, the connecting rope, the fixing ring and the first bearing structures are arranged, so that the problems that automatic pouring can not be achieved, and the lifting function is not achieved are solved.
