A drip tape winder for easily and cost-effectively rolling lengths of drip tape in the field is described. The winder comprises a frame and a mandrel rotatably received in the frame and utilizes a battery powered drill to provide the power necessary to turn the mandrel and neatly wind lengths of drip tape thereon.

The present invention provides a telescopic jacking stepwise rollback-type reel sprinkling irrigation machine, including 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 lifting cylinder, an upper caliper, and a lower caliper, and the upper caliper and the lower caliper are clamped to be mounted on the locking channel. Pressurized water is used in the telescopic jacking stepwise rollback-type reel sprinkling irrigation machine to drive the lifting cylinder to realize periodic lifting motion of the piston rod, 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.

A nozzle height adjustment subsystem for use with an irrigation system comprises a spool, a rotation device, and a control device. The spool includes a central hub and is configured to retain a drop hose to which a nozzle is attached. The rotation device is coupled to the spool and rotates the spool in a first direction or a second, opposite direction when it is activated. The control device includes electronic circuitry that is configured to generate a signal that activates the rotation device.
