Flexible rotary harrowabstractThe invention relates to agricultural engineering. Flexible rotary harrow comprises designed for installation on a vehicle frame with fixed on it is rotatably flexible chain element consisting of at least two modules in each link which are fixed teeth, and on the frame via at least two brackets for each holder installed, at least two holder module flexible chain element, module holders are fixed at an angle to the direction of movement of the harrow, wherein the teeth are rigidly fixed crosswise on each link stranded th element of the chain. The frame harrows may be further installed at least one remote bracket, which fastens the module holder flexible chain member. Angle fixing holder module can be changed as appropriate by changing the position of the brackets on the frame followed by fixing. Holders modules flexible chain member may be arranged in parallel or nonparallel to each other. The number of teeth on each link of the chain element can be from two to eight. The teeth of the chain element can be made straight and / or curved and / or bending and / or curved. The teeth of curved and / or with a bending may have a bend radially towards the rotation harrows or in the direction opposite to the rotation of the harrow. The cross section of the teeth of the chain member may have the shape of a regular polyhedron. The teeth of the chain elements at both ends may be oblique cut. Changing the length of the module carrier can be carried out with the help of a telescopic assembly, fixing the desired length of the module carrier - using the lanyard. Harrow may further comprise brackets for the attachment of the module holders flexible chain member with rotating axles and springs, connecting modules to the frame holders. Such constructive arrangement flexible rotary harrow provides improved quality soil band treatment.Гибкая вращающаяся боронаРефератПолезная модель относится к сельскохозяйственному машиностроению.
