ConclusionsMulti-body the evaluation in the AF among the roller plus the track groove, the AF According to dynamics (MBD) and discrete element process (DEM) coupling simulation are carriedgentle in most ofeffects of forward the difference isn’t apparent below differis fairly out to study the the method, and velocity (FV) and ground clearance of spring teeth (GCST) to pick-up loss rate there is a much more force (AF). peak for the duration of a model can ent working conditions. Nevertheless,(PLR) and acting substantial Picker couplingmovementcycle. As illustrated within the above analysis, the interaction amongst the straw and also the spring teeth includes a negligible impact around the AF. The structure from the track groove is unreasonable within a certain region, which KG5 Protocol results in a sudden adjust of AF when the roller moves to this region. This phenomenon is dangerous to the picker, which not simply increases the vibrationMachines 2021, 9,15 ofwell describe the motion method of straw selecting, pushing and throwing, leading towards the following conclusion:Forward velocity (FV) and ground clearance of spring teeth (GCST) had a significant effect on pick-up loss rate (PLR), and had little impact on acting force (AF). As a result, as forward velocity (FV) and ground clearance of spring teeth (GCST) boost, pick-up loss rate (PLR) increases. The morphological adjustments for the duration of the movement of straw were analyzed as well as the regions through which straw passes have been divided. The congestion mainly occurs within the pushing location, and optimizing the structure of your detention area can enhance the smoothness of straw conveying. Via the evaluation of the acting force (AF) among the roller plus the track groove, it’s concluded that the structure of the track groove is defective within a certain location, that will lower the service life with the picker and will be studied in depth within the future. The experiments show that the approach is feasible and effective. Numerical simulation of straw motion according to automatic dynamic analysis of mechanical systems (ADAMS) and discrete element strategy (DEM), which can present initial situations and parameter configuration for future coordinated operation among unmanned tractors and balers.Author Contributions: Conceptualization, L.C.; methodology, Q.W.; software, Q.W.; validation, Z.B.; formal analysis, Z.L.; investigation, D.X.; resources, L.C.; information curation, Q.W.; writing–original draft preparation, Q.W.; writing–review and editing, L.C. and H.W.; supervision, Z.L.; project administration, Q.W.; funding acquisition, L.C.
