SUBSTANTIATION OF THE DESIGN SCHEME AND MAIN PARAMETERS OF A DEVICE FOR PRE-CLEANING RAW COTTON BEFORE STACKING ON THE BASIS OF THE KLP-650 BELT CONVEYOR

This thesis considers the design of a device for cleaning raw cotton of foreign matter before stacking, built on the basis of the KLP-650 belt conveyor. The device consists of a rotating pin drum mounted above the belt at a distance of 1.0–1.5 m from the loading zone and a mesh surface beneath it. Cleaning takes place directly in the existing conveying flow, without additional floor space, transfer units or reloading. Conditions for selecting the pin length (0.5·h ≤ lp ≤ h − Δ), the mesh opening size and the belt speed are substantiated, the limits of the drum rotation speed are determined, and the absence of resonance is checked (forced vibration frequency of 53.3 Hz at z = 8 and n = 400 rpm).
