Abstract
The threshing process consists of a number of elementary technological operations, the duration of each of which proceeds during a time of 0.002-0.004 s. surrounded by one bar. In this article we present the calculation of the parameters of the threshing zone using the law of compression. A model of an elementary technological operation has been developed that makes it possible to determine probability of threshing, Calculate the parameters of the working elements of the output zone of the underdrum space of the threshing apparatus of a combine harvester.
Highlights
Threshing occurs as a result of impacts at the entrance and rubbing of ears at the output of the threshing space
An analysis of the plant mass showed that, when the combine harvester is close to the optimal operating mode, a considerable fraction of the losses are formed by a ragged ear
Such forces, initiated in the layer with a single passage of the flail over a portion of the bread mass moving along the smooth surface of the underdrum space, constitute an elementary technological operation of threshing
Summary
Threshing occurs as a result of impacts at the entrance and rubbing of ears at the output of the threshing space. It is actual to calculate the operating parameters of the underdrum exit zone, as one of the main structural elements of the threshing device..
