Experimental studies method of controlled gravitational leakage of grain materials from physical model of dump hopper

Abstract

In the article, for the purpose substantiate the parameters and operating modes of the harvester`s unloading devices, the method of experimental studies of controlled gravitational leakage from the dump hopper and its physical model is proposed. The peculiarity of the program for the study of free-flowing material`s leakage involves three stages, which include a joint common goal, individual experiments, the execution of which ensures the verification and, if necessary, the correction of the theoretical provisions, considerations and conclusions on improving the efficiency of the production process of harvesting grain crops. The research consisted of: the original experiment (the establishment of mechanical and technological properties of the working grain material of the main crops); modelling (construction and verification of the dump hopper`s physical model); the main experiment (studying the movement of grain from the dump hopper).
