Abstract Combine with the research of accessory nozzle of Model 11CP45 sprinkling machine of hydraulic and propeller by oneself made by Shanxi Shineland Group Co., Ltd., the theory analyse of freedom spray of the column and common outside pipe nozzle is studied. The contractive nozzle is designed and efflux device is increased. Through testing calculating, water loses coefficient reduces, and velocity of flow coefficient increases. The flow of the nozzle is increased by 8%.The range is increased by 5%.The result is remarkable.
