Results of studies of the power of installed engines and the mass of self-propelled rod sprayers

Abstract

Plant protection and the application of mineral fertilizers play an important role in the production of agricultural products. To improve technological processes and develop new models of self-propelled rod sprayers, it is advisable to determine the laws of distribution of their technical parameters. A number of the power distribution of the installed engines of self-propelled rod sprayers has a coefficient of variation of 30.4%, which indicates that the distribution is close to normal. For 95% of the considered models of self-propelled sprayers, the power value of the engines is in the range of 55.1 ... 225.3 kW. It changes approximately 4.1 times, which indicates the presence of many different factors that significantly affect the design features of self-propelled sprayers. In particular, this may be related to consumer requests. Theoretical and empirical laws of a series of mass distribution of self-propelled rod sprayers are presented. The studied indicator has a coefficient of variation equal to 35.1%. With a confidence probability equal to 0.95, it is calculated that the weight of the rod sprayers is 2.69 ... 15.35 tons.
