Abstract: The present disclosure provides a system for monitoring a scraper chain based on a measurement on transmittance of a torsion spring and a method thereof. The system includes a sprocket-wheel torsion detection device, a fixing device, a wireless receiver, an A/D converter and an industrial computer. In the method, the relative torsion of the two sprocket wheels is converted into the density change of the torsion spring, the light transmission area is converted into the current value by the laser sensing panel, a varying range of the torsion spring is calculated by the industrial computer through the preset threshold and its own program to monitor the operating conditions of the chain. The method has a novel concept, a stable and reliable system, and a high promotion value.

Abstract: 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.
