ARTICLE ANNOTATION

quote
The article analyzes the movement of raw cotton in the current UXK cleaning line. Experience has shown that when raw cotton is fed from the section of the chopping drum to the saw section and from the saw section to the subsequent chopping section, violations of the steady movement of raw cotton are detected, i.e. raw cotton does not move along the established trajectory in the upper part of the drums moves back. It is shown that a certain part of which, passing between the spike and brush drums, falls down onto the mesh surface, and the remaining parts, moving along the upper part of the cleaner, reach the initial spike section. As a result, the steady movement of raw cotton along the cleaning line is disrupted, the amount of raw cotton in the working chamber and the mechanical impact increase, which leads to a deterioration in the quality of fiber and seeds. Observation has established that in the saw section, when raw cotton is thrown by a guiding brush drum onto the surface of the saw blade, raw cotton particles not captured by the tooth are thrown on an inclined surface located in the upper part of the fixing brush and, due to an insufficient angle on this surface, raw cotton is impaled. It has been revealed that when raw cotton is thrown onto a spike drum using a removable drum, some of it reaches the upper wall of the cleaner due to high speed, accumulates and reverses.
