一种粮食收割机振动筛选架
By designing fish-scale screen plates and R-shaped pin structures that overlap at both ends on the vibrating screening frame of the grain harvester, the problems of small screening area and time-consuming replacement are solved, achieving more efficient grain separation and convenient replacement.

AI Technical Summary
The fish-scale screen teeth of existing grain harvesters are relatively short, resulting in a small screening area, making it difficult to effectively separate grain and impurities, and easily causing grain to slip away. Moreover, replacing the fish-scale screen plates is time-consuming and labor-intensive.
A vibrating screening frame for a grain harvester was designed, which uses fish-scale screen plates to form a stacked structure, increases the length of the screen tooth plate, and enables quick installation and replacement of the fish-scale screen plates through R-type pins and shaft frame structure. The gap between screen holes is reduced, the screen surface is flat, and the screen plate surface is set with arched protrusions to improve the screening effect.
It effectively prevents grain from slipping through, improves cleaning effect and uniformity, reduces grain loss, increases screening efficiency and equipment assembly efficiency, and simplifies the replacement process of fish scale screen plates.
