Tine element and agricultural machinery

摘要

A tine element which is installed on a rake wheel of an agricultural implement which displaces harvested products such as hay and cut grass, the tine element comprising a first and second tine with the outboard end of each tine being disposed so that it points normal to the direction of travel of the tine element around the axis of the rake wheel. Each of the tines has on its inboard end a coiled part and such coiled parts are joined by a common central part. In operation, one of the tines is disposed above the other tine with the lower tine being longer than the upper tine. The coiled parts comprise coil torsion springs and each part has different elasticity characteristics so that the resilient deflection of the lower tine is greater than the relative deflection of the upper tine and the flexibility of the each tine is optimized to obtain better adaptation to the ground and to provide a longer life span for the tine element.
