The present invention provides a wireless interconnection control system for improving sprinkler irrigation uniformity of hose reel irrigator with electric drive comprising a micro processing controller module, a frequency converter, a water pump AC motor, a pressure transmitter, a GPRS wireless transmission module, a mobile phone client APP, and a coding speed detection module. The microprocessor controller module and the frequency converter form a pressure PID controller to indirectly control the constant nozzle inlet pressure by controlling the pressure of the incoming pressure of the hose reel irrigator. The microprocessor controller module and the matching motor controller with brushless DC motor form a speed PID controller to directly control the reel back speed of the PE pipe. The GPRS wireless transmission module interactively communicates the nozzle inlet pressure, the reel back speed of the PE pipe and the mobile phone client APP through the short message mode. After setting the corresponding parameters, the system realizes the automatic adjustment of the working conditions, improves the uniformity of the sprinkler irrigation operation of the hose reel irrigator, and realizes the remote real-time and precise monitoring of the working conditions of the hose reel irrigator, which provides a front-end guarantee for the intelligent irrigation of the irrigator.

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 self-priming water turbine-driven reel sprinkler irrigation machine includes a framework, a plug board, a reel, a PE pipe, a water turbine driving device, a sprinkler wagon, and a self-priming device. The framework comprises an underframe, a reel support frame, a plug board support frame, and a wheel assembly. A bottom portion of the underframe is provided with an underframe rotary device, and the underframe rotary device comprises a rotary bearing and a chassis support member. An inner ring of the rotary bearing is fixedly mounted to the underframe, and an outer ring of the rotary bearing is fixedly mounted and connected to the chassis support member. A telescopic front support is disposed at a front part of the underframe. The wheel assembly comprises a wheel support beam, a wheel, and a wheel lifting hydraulic cylinder. The self-priming device comprises a water pump, a pumping hose, and a filtering mechanism.
