Abstract： To address common issues with existing silage round baling machines in China，such as material scatering， frequentblockagesatthefeedinlet，lowbalingdensity，andhighfailurerates，thisstudypresentsthedesignofabelttype baling machine.The machine consisted of a primary silo，a secondary upper silo，a baling chamber，a mesh device，a blanking and recycling unit，a film wrapping system，a wrapping table，a film-cuting tool holder，as well asintegrated electronic control systemandahydraulic system.First，theoretical calculations and3D parametric modeling were employed to carry out the dynamicanalysisand structural design of the baling chamber.Next，the material baling mechanism was studied in depth，witha focus on the force conditions acting on the grasscore andbaleduring the three keystages：core formation，belt deformation，andbaleroling.Finally， using silage corncrushedmaterial asthe test subject，a field trial was conductedat a planting base in Gansu to evaluatehow variousbaling parameters affect bale density.The results showed that under optimal conditions where baling pressure was 0.72MPa ，belt speed was 1.4m/s ，and feeding rate was 3.4kg/s ，thebaling density reached （204号 733kg/m3 ，which falls within the standard range for silage corn crushing material （730-740kg/m3⋅ .Thebaling efficiency achieved was ⩾50 bales per hour. This research provides both theoretical and empirical support for thedesignand optimization of baling machines in China，thereby contributing toimproved performance and reliability in silage baling operations.
