Q355B Steel Threshing Drum Front Cover for Harvesters

The front drum cover is a semi-circular arched housing designed for the threshing drum of wheat combine harvesters. Fabricated from Q355B high-strength steel plate through precision bending, this cover encloses the outer side of the threshing drum chamber. During harvesting operations, it effectively prevents wheat grains from splashing outward and blocks field dust, straw debris, and other contaminants from entering the drum interior, thereby maintaining stable threshing performance and reducing grain loss in the field. All edges are deburred and rounded for safe handling, and dimensional tolerances comply with the GB/T 19804-C standard to ensure precise fitment. The cover is pre-punched with assembly holes for secure locking onto the end of the threshing drum chamber. As a company specializing in machinery manufacturing, we maintain rigorous quality control throughout the bending, welding, and finishing processes, delivering components that meet both OEM specifications and afterma…
