Abstract

Hopper installations are the main constituent of machines units of agricultural production. They are used in operations connected with storing, transporting and processing of loose grain materials. In spite of the simplicity of construction they have a serious drawback relating to a certain loose material property. The loose material while being outflowed from the capacity forms arched (bridge) structures that prevent a normal gravitational outflow resulting in it acquiring an unstable character. In this work, some methodology is given to calculate a vibrational dome breaking device with a lateral outlet opening that provides a steady supply of grain of different moisture. The facility developed enabled to achieve a steady grain outflow of various moisture from bins with lateral output openings under conditions that had never been possible before. The device developed enabled to achieve a steady grain outflow of various moisture from bins with lateral output openings under conditions that had never been possible before. In general, the results obtained show that the application of dome breaking device can be used in hopper installations to ensure steady grain outflow of various moisture and low productivity.
