MACHINE FOR GRINDING AND INSERTING SOLID ORGANIC FERTILIZERS INTO THE SOIL Russian patent published in 2017 - IPC A01C3/00 

FIELD: agriculture.

SUBSTANCE: machine comprises a hopper, in which a horizontal feed conveyor, grinding reel, and accelerator reel are located, and they are provided with toothed elements. Feeding horizontal conveyor is provided with cutting knives and adapted two-piece is mounted at the top of the silo above the solid organic fertilizers and is driven by a hydraulic motor. Sections of horizontal conveyors are controlled by hydraulic cylinders, working from the tractor's hydraulic system. The cutting blades are made trapezoidal belts with double-sided sharpening, the blade set at an angle of friction of the solid organic fertilizer to the direction of the moving mass of fertilizer. Cutting blades are mounted on rails placed on the conveyor in a staggered manner. The conveyors are mounted in the hopper to move vertically along the guide cylinders and their lateral control cylinders in position when lifting loading hopper. At the rear of the hopper to adjust the amount of fertilizer supplied to the chopping reel and reel-accelerator provides the privacy shutter. Chopping reel and accelerator reel are placed behind the shutter and are made from the square profile, the side walls of which are fixed toothed elements are made in the form of grinding blades trapezoidal shape and placed onto the shaft along a helix and gap between oppositely rotating knives 3…5 mm. Under the reels screw-valve is mouned, placed in the grill housing and having a different winding direction from the center. Distributor screw length is bigger than the hopper's width. To the bottom of the hopper by means of leads, the harrow is mounted, controlled by hydraulic cylinders. The reel and screw drive are made by hydraulic motors working on the hydraulic system of the tractor.

EFFECT: uniform distribution of organic fertilizers in the root zone of the soil, reducing the energy intensity of fertilizer application.
