阅读：31发布：2023-12-30

专利汇可以提供Feed mechanism for hay balers专利检索，专利查询，专利分析的服务。并且A hay baler with a bale chamber, a feed opening in one side wall of the chamber, a plunger in the bale chamber for compacting hay, a hay receiving platform extending laterally to one side of the bale chamber, a track mounted above the platform, a feeder carriage mounted on the track for movement along the track to convey hay from the platform and through the opening in one side wall of the chamber, and a drive transmission mechanism to reciprocate the feeder carriage. The drive transmission mechanism includes a resiliently extensible link pivotally connected at one end to the plunger, a floating link pivotally connected to the other end of the drive link, a connecting link pivotally interconnecting the floating link and the feeder carriage, and first and second swinging arms each pivotally connected at one end to the floating link at spaced apart positions along the length thereof and pivotally mounted on spaced apart pivot members on the bale chamber.，下面是Feed mechanism for hay balers专利的具体信息内容。

权利要求

1. A drive transmission mechanism for transmitting reciprocating motion comprising a drive link pivotally connected at one end to a reciprocable drive member, a floating link pivotally connected to the other end of the drive link, a connecting link pivotally interconnecting the floating link and a member mounted for reciprocating movement, and first and second swinging arms each pivotally connected at one end to the floating link at spaced apart positions along the length thereof, the swinging arms being pivotally mounted on respective spaced apart pivot members located at fixed positions relative to the floating link.

2. A mechanism as claimed in claim 1, in which said drive link is resiliently extensible.

3. A mechanism as claimed in claim 1 in which said floating link comprises a box-section beam having first and second pairs of plates, one pair at each end and the plates of such pair on opposite sides of the beam.

4. A mechanism as claimed in claim 3, in which said connecting link is connected through said second pair of plates to the floating link.

5. A mechanism as claimed in claim 3 in which said first swinging arm is connected through said first pair of plates to the floating link.

6. A mechanism as claimed in claim 3 in which said drive link is connected to said floating link through first pair of plates at a point off-set from the longitudinal axis of the floating link.

7. A mechanism as claimed in claim 1 in which said second swinging arm is formed as a pair of spaced parallel links each connected to said floating link through a trunnion located intermediate the ends of the floating link.

8. A mechanism as claimed in claim 1 in which said drive link comprises a pair of side arms pivotally connected at one end by a trunnion block adapted to be reciprocated at at the other end by a U-shaped end cap, a rod adapted for connection at one end to the floating link and passing through an aperture in the end cap, a pin provided at the other end of the rod and cooperable with a slot in one of the side arms and compression spring surrounding said rod and extending between the end cap and said pin.

9. A hay baler comprising a fore and aft extending bale chamber having a feed opening in one side wall thereof, a plunger reciprocable in the bale chamber from a retracted position forwardly of said opening to an extended position rearwardly of said opening, a hay receiving platform extending laterally from said one side wall, a track mounted above said platform, a feeder carriage with crop feeding means mounted on the track for movement along the track to convey hay from the hay receiving platform through the feed opening in one side wall of the bale chamber, and drive means connecting the feeder carriage to the plunger to reciprocate the feeder carriage back and forth characterized by a drive link pivotally connected at one end to the plunger, a floating link pivotally connected to the other end of the drive link, a first and second swinging arms each pivotally connected at one end to the floating link at spaced apart positions along the length thereof and pivotally mounted on the bale chamber at spaced apart positions, and a connecting link pivotally connected to the feeder carriage and the floating link.
