Studying the Law of the Movement of Cotton Particle on a Saw Cylinder and the Interaction with Saw Teeth

摘要

This article investigates the movement trajectory of the cotton particle from Point D of belt transporter of the saw gin camera to Point B of the saw cylinder. In other words, the forces acting on the cotton particle and the equations of their interactions are developed, where, the differential equation of the law of movement of the cotton particle “belt + saw” is made according to the d’Alembert principle. Arc-BD of cotton particle gives the length of the arc of their fall on the saw teeth. The maximum separation of fibers and the quality of separation of fiber from seeds, as well as the time (t) of rapid separation of fiber from seeds, depend on the length of the arc-BD, because the critical length of the arc-BD makes it possible to reduce the multi-layering of the falling cotton particle on the saw teeth. In this scientific research work, patented by the new working camera of the saw gin, the trajectories of the movement of the cotton particles along the arc-DB, as well as the trajectory of the move in the direction of the grate are studied. The results of the study show that the number of fibers increases along the height of the teeth of the saw with one touch. This leads to a decrease in the average stay of seeds in the working chamber of the gin. As a result, the efficiency of the saw gin is increased.
