The utility model discloses a rotary drilling rig power head device with a high-speed soil throwing function. The rotary drilling rig power head device is characterized in that a low-speed reducer (1) is connected to a gearbox (14) by use of a clutch steel cylinder (3), one end of a spline shaft (2) is rotatably connected with the output shaft of the low-speed reducer (1), the internal spline of a sliding spline housing (4) sleeves the spline shaft (2) in such a manner that the spline freely slides up and down, the main shaft of a driving gear (6) is connected with a gear sleeve (5), the external spline of the sliding spline housing (4) is connected with the gear sleeve (5) in such a manner that the spline freely slides up and down, one end of a shifting fork (9) is connected with the sliding spline housing (4), while the other end of the shifting fork (9) is connected with the piston rod of a shifting fork oil cylinder (8), and the shifting fork oil cylinder (8) is mounted on the clutch steel cylinder (3) and used for driving the sliding spline housing (4) and the gear sleeve (5) to be separated from or closed to each other. The rotary drilling rig power head device with the high-speed soil throwing function is reliable in operation, simple in structure, stable in working, convenient to repair and low in manufacturing cost.
