摘要:
An in-feed apparatus is disclosed for a forage harvester having upper and lower feed roller assemblies mounted in a frame, the upper feed roller assembly (120) being movably mounted in the frame (18) to vary the separation between the two assemblies and being biased by springs (55) towards the lower feed roller assembly (17) so as to apply a compressive force to crop material passing between the upper and lower feed roller assemblies. The in-feed apparatus further includes a stop for limiting downward movement of the upper roller assembly so as to set a minimum separation between the two feed roller assemblies. In the invention, the stop comprises a cable (90, 91, 92 and 93) secured at one end to the upper roller assembly and at its other end to the frame.

A tensioning system for a drive belt (18) of a blower of a forage harvester, comprises a tensioning roller (22), a rod (34) for moving the tensioning roller (22) towards and away from the belt (18), a spring (40) surrounding the rod (34) and acting between a first abutment (36) mounted on the rod (34) and a second abutment (42) connected to the chassis (10) of the harvester to urge the roller (22) towards the belt (18). The chassis connected abutment (42) is carried by an arm (26) that is movable relative to the chassis (10) and anchored by means of a tie bar (30).
摘要:
A spring system (122) is described for a feeder device (101) of an agricultural harvester having a first roller movably mounted in a casing (105) and biased by the spring system towards a second roller (107) in order the compress crop passing between the two rollers. The spring system comprises at least one spring (124) surrounding a guide rod (200) that extends in use between a movable support of the first roller and the casing of the feeder device. The guide rod (200) is formed of two telescopically collapsible parts (210, 212), one connected to the roller support (108) and the other to the casing (105).

摘要:
A roller assembly (30) for a belt drive system (1) of an agricultural machine, the roller assembly (30) having a shaft (50), a roller (20, 22) rotatably mounted on said shaft (50), and adjustment means for adjusting the position of the shaft (50). The adjustment means comprise means (62, 64) for angular adjustment of the position of the shaft (50) in two distinct directions (X, Y).
