Description

Technical Field

[0001] The utility model relates to the field of balers, in particular to an external bearing type guide for a round baler. Background Art

[0002] With the rapid development of the economy, the development trend of the animal husbandry is good, and the demand for forage grass is increasing day by day. Natural forage grass can no longer meet the needs of the development of animal husbandry. Therefore, corn straws and wheat straws have gradually become the forage for animal husbandry in some areas. There are many types of mechanized harvesting of forage grass, and the most commonly used mechanized harvesting equipment is a square bale baler and a round bale baler.

[0003] In a traditional round baler, the guide is an important component of the baler. Its function is to send the hay strip picked up by the picker to above the picker, ensuring the pre-compression of the hay strip and evenly feeding it into the feeding port. The roller at the front end of the guide rotates by rubbing against the forage grass. If it rotates flexibly, it can play a role in pre-compressing the hay strip. If it rotates inflexibly, it will push the hay strip forward, causing the hay strip to become congested in front of the machine. There are two assembly methods for the bearing seats on both sides of the guide roller: one is to assemble the stamped flange circular seat (PF type) tightly against the roller end plate. The whole bearing seat rotates with the roller, and the assembly point of the large arm weldment of the guide and the roller is on the roller end plate, and the coaxiality is not easy to ensure, and rotation is prone to jamming. The guide roller with jamming rotation will increase the difficulty of picking up when it plays a role in pushing the grass. The other is to assemble the spherical roller bearing with eccentric sleeve and convex circular seat (UELFC type) on the guide arm. This structure requires sufficient space on the front connecting plate of the guide, wasting materials. Summary of the Utility Model
