WINDROW MERGER AND PICKUP HEAD

摘要

A windrow merger includes heads having cams that control the speed of the tines. The cam is configured with a section that slows the speed of the tines while passing a lower front portion of the path of rotation to lift material from the ground at lower speeds and therefore handles the material more gently at the point of pickup. The cam is configured to accelerate the tines at the point where the lifted material is propelled rearward from the pickup assembly. The merger heads also include a widened conveyor that is configured with an upper surface extending rearward and slightly downward to further evenly distribute material across the width of the conveyor. The heads are supported on skids that have a linkage connecting the skids at each end of the head with one of the skids having a mechanism that acts as a master to control the slave of the linked opposite skid.

主权项

1. A windrow merger having a front and a rear and configured for moving along a direction of travel, the merger comprising:
a frame; a head; the head comprising a pickup assembly, the pickup assembly comprising: a plurality of tines rotating about a rotational axis extending transverse to the direction of travel spaced along and around a periphery of the head and extending radially outward; a cam follower supporting the tines; a cam defining a cam surface, the cam surface comprising: a first portion proximate a lower front portion of the cam and having a configuration for imparting a first tine speed for tines passing over the first portion; a second portion proximate an upper front and top portion of the cam and having and having a configuration for imparting a second tine speed for tines passing over the second portion, the second tine speed being greater than the first tine speed; and a conveyor rear of the plurality of tines.
