DISK SHOVEL Russian patent published in 2008 - IPC A01B23/06 

FIELD: agriculture.

SUBSTANCE: invention refers to agricultural mechanical engineering and can be used tilling operations. The disk shovel is made in the form of the spherical disk established by camber upwards and fixed on a support which is located in the centre of the disk. The disk contour has the form of gear. The support is made from two upper and bottom parts, connected pivotally. The upper part of the support is supplied with two symmetrically located ribbon springs. The springs are fixed rigidly from two opposite sides of the upper part of the support, and the spring part is adjoined to corresponding planes of the bottom part of the support below the hinge for keeping in working position. The disk on the bottom part of the support is fixed pivotally with possibility of free rotation around vertical axis. Disk teeth are executed in such a manner that one tooth has length twice more than the next tooth. Teeth are located in different planes, two-leveled, with equal step and with alternate sequence. Such constructive performance allows increasing quality of tilling operations.

EFFECT: improved quality of tilling operations.
