Sprinkling machine for seedling culture and maintenance

The invention relates to the technical field of agricultural production, and discloses a sprinkling machine for seedling maintenance, which is characterized in that a limiting pipe is not provided with a through hole, so that water which enters an inner cavity of the limiting pipe and is positioned below a circulating hole is in a non-flowing state; water entering a limiting pipe and located in a containing cavity above the adjusting device can enter the sprinkling irrigation device through a rectangular through hole, is sprayed out from the sprinkling irrigation end of a nozzle and impacts a direction changing plate, the direction of the sprinkling irrigation water is changed under the blocking of the direction changing plate, meanwhile, the direction changing plate rotates under the action of impact force, and therefore the sprinkling irrigation effect is achieved. Then, the sprinkling irrigation device is driven to rotate in the same direction, so that a turning plate is in contact with water sprayed out o
