The invention relates to the technical field of agricultural
intelligent equipment and discloses a pneumatic buffering
transplanting and positioning mechanism for flower seedlings. The mechanism comprises parallely arranged gantry supports; a horizontal guide rail is arranged on each support crossbeam; two symmetric idle
pulley fixing plates are mounted through horizontal slide blocks, and the inner side of each idle
pulley fixing plate is connected with the vertical guide rail of each vertical plate through a vertical slide block; the lower part of the inner side of the vertical plate is connected with a crossbeam used for installation of a clamping paw; a synchronous draw gear composed of motors, synchronous belts, synchronous pulleys, synchronous wheel shafts, idle pulleys and tensioning wheels drives the vertical plates to horizontally move along the horizontal guide rails and vertically move along the vertical guide rails so as to drive the clamping paw mounted on the crossbeam to move, so positioning in the process of
transplanting of seedlings is realized; the positioning mechanism has a compact structure and moves smoothly; furthermore, buffering air cylinders are arranged between the vertical plates and the idle
pulley fixing plates, and through the buffering air cylinders, self-weight load of the vertical plates is offset, inertial
impact is buffered, and driving load of the motors is reduced.
