The invention mainly relates to a pulley type slider coverage greenhouse transmission device which comprises a transmission system and a connecting system of multi-layer covering parts. The transmission system comprises a reducer, a rotary shaft, steel cables and pulleys. One end of the first steel cable is wound on the rotary shaft, and the other end of the first steel cable is guided to be connected to a D end of a covering part Z through multiple pulleys. One end of the second steel cable is wound on the rotary shaft, and the other end of the second steel cable is guided to be connected to an E end of the covering part Z through multiple pulleys. The first steel cable and the second steel cable are reversely wound on the rotary shaft. The connecting system of the multi-layer covering parts comprises rotating angle irons, connecting rods, a rotating rod, a hinge support, a spring, a non-return block and a colliding block. By the pulley type slider coverage greenhouse transmission device, accurate opening and closing control of the thermal-insulating covering parts are achieved, the safety problem that traditional thermal-insulating quilts and roller shade devices hurt operators is solved, and safe and stable operation of the multi-layer covering parts is guaranteed.
