DEVICE FOR INTRODUCING SOLID ORGANIC FERTILIZERS INTO SOIL Russian patent published in 2017 - IPC A01C3/06 A01C15/00 

FIELD: agriculture.

SUBSTANCE: device for introducing solid organic fertilizers into the soil includes a frame with supporting wheels on which a body with transporting working bodies with a drive and spreading working bodies with a drive are installed. The body is made sectional, and is able to change the tilt angle of the sections relative to the horizontal plane in the transverse direction. The sections are equipped with rotary axes, hydraulic cylinders and vibratory plates driven by a hydraulic motor. The sections are connected to a hopper located in the center of the body, having a bottom with inclined walls, with installed vibratory plates driven from the hydraulic motor, coupled with an adjustable concave having knives. Above the concave a grinding drum is mounted, driven from a gear unit, made in the form of a hollow cylinder, on the side wall of which there are cutting knives placed along screw lines, and the cutting edge of the knives is made in the Archimedes spiral. Under the frame, a belt supply conveyor is mounted, equipped with a restrictive casing, whose length is equal to 1/2 of the body length. The drive of the belt supply conveyor is made from the gear unit. At the rear body part there is a distribution screw having a two-way direction of the winding from the screw center, in the lattice casing, the length of which is more than the body width. The drive of the distribution screw is made from the gear unit. At the rear body part, by means of swivel arms controlled by hydraulic cylinders, a harrow-hoe is mounted, the width of which is equal to the length of the distribution screw.

EFFECT: increasing the performance, improving the soil fertility without additional technological operations, increasing the yield of agricultural crops.
