发明名称 Ridge forming apparatus
摘要 A ridge forming attachment for cultivators of a type having a plurality of earth working blades thereon for eliminating weeds between rows of crops growing in the field. The ridge forming attachment includes a bracket adapted to be attached to such cultivator rearwardly of one of the earth working blades thereon. A ridge forming wing structure is provided for moving the soil loosened by the earth working blades which it follows between the rows of crops and pushing such loose dirt to each side to form ridges along the rows of growing crops. The ridge forming structure is narrower at the front thereof and progressively tapers outwardly towards the rear of the space between rows for pushing the soil from such space between the rows outwardly towards the rows of growing crops. A connection structure is provided for operatively pivotally attaching the ridge forming structure to the bracket along a substantially vertical axis whereby the ridge forming structure will precisely track behind the earth working blades for permitting the ridge forming structure to be temporarily deflected from one side to the other in the event that rocks or other potentially damaging obstacles are encountered, and for tracking precisely behind such earth working blade even at those times when the row is not exactly straight.
