AGRICULTURAL UNIT FOR HIGH-SPEED SURFACE CULTIVATION OF SOIL Russian patent published in 2004 - IPC

FIELD: agricultural engineering, in particular, complex surface soil cultivation by means of self-propelled energized vehicle.

SUBSTANCE: agricultural unit has frame with carrier wheels at its ends, transverse beam attached to frame and equipped with vertical tines, triangular metal flat hoes fixed to vertical tines, and mechanism for tightening of rotating chain module mounted on frame rear part and provided with mellowing teeth fixed on chain links. Agricultural unit is further provided with double-roll disk-type soil grinder having disks immovably positioned at an angle to longitudinal axis of square shaft. Frame carrier wheels are equipped with soil removal device. Carrier wheel spacing is equal to width of track of vehicle adapted for advancement of agricultural unit. Point cover applied onto cutting edges of metal flat hoes is made in the form of directed circles of wear-resistant material. Vertical knife is provided with directed continuous cutting edge adjoining vertical tine and is attached to flat hoes. Chain module teeth are simultaneously fixed at two angles to longitudinal axis of link and to its surface. Soil grinder disks are mounted on single shaft at equal angles. Soil grinder disks may be mounted on different disks at equal angles or may be inclined in opposite directions. Spacing between soil grinder shafts may be selected in such a manner that disks fixed on one shaft enter clearances between disks on other shaft. In this case, shafts are connected by chain contour to provide for synchronized rotation thereof.

EFFECT: stabilized soil cultivation depth, improved quality of displacement and grinding of soil in transverse direction and uniform leveling of soil.
