Abstract

The article presents the advantages of harvesting grain ears by the method of combing at the root use stripper harvesting module technology with subsequent processing in comparison with combining. Harvesting with this technology is performed by a trailed harvesting machine with stripper working bodies. The implementation of this technology is constrained by namely the lack of scientific substantiation of the operating modes of the pneumatic conveyor of the combed heap. In this regard, there is a problem of researching the pneumatic conveyor, for its solution a method of experimental research was developed, which will determine the optimal parameters and performance of the pneumatic conveyor combed heap.The results of experimental researches of technological process of the pneumotransporter for transportation of the combed heap of grain in the trailer - the cart, namely range of flight of the combed heap depending on frequency of rotation dampers. The parameters of the factors and the geometric dimensions of the experimental setup were determined by computer simulation in SolidWorks. During the simulation, a full-fledged computer model was developed in real size, where the parameters were obtained by changing the speed of the impeller and changing the geometry of the loading window and the pneumatic line. Using the results of theoretical research, modeling and analysis of literature sources, the limits of the values of the factors were determined, which are given in the table. To conduct experimental research, an experimental setup was made, which allowed to vary the values of variable factors, and thus obtain a variety of data on the range of the combed pile of wheat depending on the values of variable factors. It is established that it is most expedient to use a noncomposite three - level Box - Benkin plan for three factors, which makes it possible to obtain a mathematical model according to the conducted experiments. The mathematical model is obtained, which in the future will make it possible to establish rational parameters and modes of operation of the compressed heap pneumatic conveyor. Checking the significance of the coefficients. The significance of the regression coefficients indicated that all the coefficients are significant. Checking the adequacy of the model showed that the model is adequate.
