Abstract
An agricultural implement, such as a baler, has a fly-wheel connection that disconnects drive to the ram and other baler parts upon overload. The fly-wheel includes a first member on a driving shaft that is connected to a second member on a driven shaft through at least one shear pin. Preferably, there are a plurality of pins that can be advanced upon overload and reduction in driving speed, to automatically re-establish connection between the two members.
Claims12
A baler comprising a pressing ram and a driving mechanism that drives said ram, said driving mechanism comprising a fly-wheel, said fly-wheel comprising a first member and a second member connected by shear means for rotation together about a common axis, said first member being mounted on a driving shaft and said second member being mounted on a driven shaft, the two members being relatively rotatable with respect to one another about said axis upon overload, said shear means including at least one shear pin slideably mounted in a holder and said pin normally interconnecting said members to prevent relative rotation until overload fractures said pin, advancement means operatively associated with said pin that automatically displaces the remainder of the fractured pin with respect to said axis following overload into operative position in which the two members are reconnected and relative rotation between the two members prevented.
A baler comprising a pressing ram and a driving mechanism that drives said ram, said driving mechanism comprising a fly-wheel, said fly-wheel comprising a first member and a second member connected by shear means for rotation together about a common axis, said first member being mounted on a driving shaft and the second member being mounted on a driven shaft, the two members being relatively rotatable with respect to one another about said axis upon overload, said shear means including at least one shear pin slideably mounted in a holder, said pin having severable portions and normally interconnecting said members to prevent relative rotation until overload fractures a portion of said pin, advancement means bearing on said pin to automatically displace the remainder of the fractured pin laterally with respect to the axis following overload into operative position that reconnects said two members and prevents relative rotation between the two members, said advancement means normally urging one of the portions of the pin from said first member into a cavity in the second member, said cavity having a recess positioned to receive the fractured pin portion and automatically discharge same upon relative rotation between the members.
