发明名称 Spring assembly for a wheel rake
摘要 The V-rake has an elongated tow beam with a front end adapted to be connected to a towing vehicle and a back end fixed to a back section, the back section is supported by a wheel assembly, which may be a set of tandem wheels. The V-rake further includes first and second rake booms each having a front end and a back end pivotally connected to the back section such that the front ends of the booms can be swung between a transport position and an operating position. The front end of each boom has at least one castor wheel for support. The back section is further adapted to controllably change the distance between the back ends of the booms to adjust the width of a resulting windrow. A number of rake wheels are mounted on each of the rake booms on the side of the boom nearest to the tow beam, wherein the rake wheels are adapted to move vertically with respect to the rake boom using a compression spring mechanism. The rake wheel includes a center disk, an outer ring and tines passing through the outer ring with the ends of the tines individually fixed to the center disk, and may further include a windguard.
