The invention relates to a gearbox type crankshaft used in a bouncing screen, and belongs to the technical field of mechanical equipment. According to the gearbox type crankshaft used in the bouncing screen, a lower gearbox and an upper gearbox can be independently opened, maintenance of a driving gear and a driven gear is facilitated, the maintenance time and cost are saved, and the maintenance efficiency is improved; besides, lubricating oil is injected into the lower gear box from a lubricating oil one-way oil injection port and then enters the upper gear box from the lower gear box, so that the lubricating oil submerges a driven gear rotating shaft, and the lubricating oil lubricates the driving gear, the driven gear and the driven gear bearing in the lower gear box and the upper gear box; and meanwhile, the lubricating oil enters a rotating block bearing through a driven gear rotating shaft oil inlet hole, a driven gear rotating shaft oil outlet hole and a crank oil outlet hole to lubricate the rotating
