RAKE FOR CUT FOREST AND SCRUB COVER Russian patent published in 2008 - IPC A01G23/06 

FIELD: technique for raking of cut forest and scrub cover, may be used in agriculture, forestry and amelioration for clearing of land from scrub and low forest.

SUBSTANCE: rake has hanger and frame system, upper and lower tines fixed along edges of frame, and guides fixed to tines. Telescopic devices are attached within interior of guides, at their both ends. Raking teeth are rigidly fixed to free ends of telescopic devices, at sides of rake. Raking teeth disposed between upper tines and lower tines are mounted on guides for movement thereon. Each of raking teeth is connected to central pivot joints of Nuremberg type shears mechanism driven by means of extension tines rigidly fixed to lower and upper pivot joints disposed in mid portion of Nuremberg type shears mechanism. Hydraulic cylinder is pivotally mounted on said mechanism. Internal pressing teeth are pivotally fixed to upper free ends of raking teeth and fixed to guide for movement thereon. Telescopic devices are disposed at both ends of guide. There are lateral pressing teeth on telescopic devices free ends, said pressing teeth being pivotally mounted on upper free ends of raking teeth. Guide is pivotally connected to hydraulic cylinder pivotally fixed to frame. Additional taking out teeth are fixed by their free ends on upper pivot joints of Nuremberg type shears mechanism. Guiding slots are provided in additional taking out teeth for receiving lower pivot joint pins of Nuremberg shears mechanism.

EFFECT: increased efficiency in clearing of lands from large sized trunks of scrub owing to the possibility of varying distance between raking teeth and width of rake, and improved quality of works related to clearing of land from small-sized forest and scrub cover.
