SOIL-DRIVEN RIDGER CULTIVATOR KGP4 Russian patent published in 2009 - IPC A01B13/02 

FIELD: agriculture.

SUBSTANCE: ridger-cultivator comprises frame, including hinged device, longitudinal beams and sides, joined by means of front and back cross beams. Frame is equipped with additional cross beam, which interacts with sides. Intermediate and side vertical rippers are installed on frame with the possibility of control in height. Rippers consist of composite stand and chisel-like knife. Upper part of stand is made in the form of plank with vertically arranged through holes and is connected by means of superimposed locking brackets with lower part. Free end of lower part is bent forward along with direction of cultivator motion and is equipped with platform. On platform there is a detachable chisel-like knife installed. Stands of intermediate rippers are fixed on longitudinal beams either in front or in back zones, or in both. Stands of side rippers are fixed either on front cross beam, or on back cross beam, or on both. On frame there are doubled intermediate and single side right and left rotation rippers arranged. Each rotary ripper consists of disk with bent knives fixed on them. Disks of rotary rippers are freely installed on axes of support forks. One end of forks in intermediate rotary rippers is hingedly installed on longitudinal beam in their front zone. One end of forks in side rotary rippers is hingedly installed on front cross beam. Other ends of forks in zone of disk supports are spring-loaded. Upper ends of springs in intermediate rippers are connected to longitudinal beams in their back zone. Upper ends of springs in side rippers are connected to sides in their back zone. Bent knives of rotary rippers with their flat surfaces are fixed on one plane of disk so that side facets of each knife are arranged on disk chords, and their free ends are bent from disk plane to create plate form. Doubled rotary rippers are fixed on axes of forks to create sharp angle, top of which is directed to the side of cultivator motion. Single side rotary rippers are turned to the side of cultivator sides. On additional cross beam there is a ridger fixed, comprising doubled middle shapers and two truncated side left and right shapers. Shapers are box-like. Each doubled shaper includes middle double-facet ploughshare with adjacent right and left extenders and central double-facet pad. Side shapers are mirror, and every of them includes truncate middle angle ploughshare, either right or left extender and truncated central pad. Each middle double-facet ploughshare is fixed on undetachable plate on its lower side, and upper side is equipped with brackets. Brackets are used to fix shapers on additional cross beam. Neighboring undetachable plates are connected with detachable plates.

EFFECT: such structural design makes it possible to reduce energy intensity of cultivator and to simplify design of its drive, to simplify assembly and disassembly of cultivator, to increase efficiency of soil cultivation, including space between rows.
