The invention discloses folding type transmission equipment for unloading barreled water. The folding type transmission equipment comprises a slide plate, wherein the slide plate is connected with a telescopic post; the telescopic post comprises a fine rod; one end of the fine rod is connected with the upper end of the slide plate; the fine rod is linked with the slide plate through a hinge; the other end of the fine rod is sleeved by a sleeve rod; the sleeve rod is connected with the lower end of the slide plate through a chain; the telescopic post is perpendicular to the ground, and a dip angle is formed between the telescopic post and the slide plate; the lower end of the slide plate is further connected with an anti-friction plate; one end of the anti-friction plate is linked with the slide plate through a hinge; and the other end of the anti-friction plate is equipped with a first baffle plate. The folding type transmission equipment can help an operator to unload barreled water from a goods van, so that barreled water does not need to unload one by one, the operator only needs to put barreled water on the slide plate on a passenger compartment of the goods van, and barreled water can glide along the slide plate, and is high in gliding speed, and therefore, the folding type transmission equipment saves time and labor, and is further convenient to carry.
