Abstract

An eccentric swinging stepwise rollback-type reel sprinkling irrigation machine includes a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a water turbine gearbox, an eccentric swinging mechanism, an upper caliper, and a lower caliper. The upper caliper and the lower caliper are clamped to be mounted on the locking channel. A water turbine is used in the eccentric swinging stepwise rollback-type reel sprinkling irrigation machine to drive the eccentric swinging mechanism to realize an eccentric swing, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.
