SOIL TILLAGE DEVICE Russian patent published in 2023 - IPC A01B35/20 

FIELD: agriculture.

SUBSTANCE: device comprises a stand, a holder, a ripper and a slotter. The holder is made in the form of a bar, the front part of which is made with a square section and is placed parallel to the horizontal surface, the back part is bent at an angle of 120° to it and is rigidly attached to the rack with the possibility of dismantling. The length of the horizontal part of the holder is 70…80 mm, and the width of the bar is 35…45 mm. A square hole 12…15 mm deep is made in the centre of the front end of the holder with side width 4…6 mm under the key of the nozzle. Along the axial line of the holder on each side there are grooves with an open slot for working bodies in the form of a ripper, slotter and two wings. The slot depth and slot height are 4…5 mm. The thickness of each platform is equal to the height of the groove and the depth of the slot. The length of the grooves of the holder is equal to half the length of its horizontal part. The ripper, slotter and two wings are made with two-stage bases, on each of their lower stages from the side of the first stage a platform with projections for the holder slots is rigidly fixed. The length of each platform is equal to the length of the holder groove, half the length of the lower step and half the length of the horizontal part of the holder. The length of the first step is equal to half the length of the platform. The height of the step of each wing is equal to half the width of the bar minus 5 mm, and for the ripper and slotter, the height of the step is equal to the height of the step of each wing minus half the thickness of the wing. The ripper and slotter are made of different heights, the angle of inclination of the wings to the axis of the bar is 35°, the grip width of the device is 300 mm, the width of the front side of the back of the holder is half that of its back side. The device is equipped with a metal replaceable nozzle, made in the form of a pyramid with a square base resting against the end of the holder. The side of the nozzle base is equal to the width of the holder bar. The nozzle is equipped with a square key rigidly fixed on it for the holder hole.

EFFECT: extension of the functionality of the device.
