Abstract

The invention relates to agricultural machinery, in particular, to devices for the subsoil application of liquid fertilizers in meadows, pastures and other untreated soils. The aim of the invention is to reduce the energy intensity of the process and improve the quality of the application of liquid fertilizers to the soil. As the battery of disks 12-13-12 moves, the extreme disks 12 rotate with greater slippage in the soil than the middle disk 13, which reduces the energy consumption for cutting holes in the soil by disks 12. The cutting disks 17 separate the ground roller between them from the rest of the array and the packing roller 16 presses this roller down. Having expanded, the roller clogs the liquid fertilizers that are introduced into the slot formed by the 12 or 13 discs. 1 Cp f-ly, 2 ill.

FIG. /

The invention relates to agricultural machinery, in particular, devices for the subsoil application of liquid fertilizers in meadows, pastures and other untreated soils.

The aim of the invention is to improve the quality of the application of liquid fertilizers to the soil.

FIG. shows the proposed device for applying liquid fertilizers to the soil, side view; in fig. 2 - the same. view from above.

A device for applying liquid fertilizers to the soil contains 1 frame 2 mounted on support wheels with working body sections 3. On frame 2, on the one hand, there is a hinged device 4, and on the other hand, conso 5, to which the articulated arm sections of the working bodies 3. Each section 3 consists of a frame 6 with a load in the form of a manifold-distributor 7, movably fixed on frame 6 and connected to hydraulic cylinders 8, screws 9 and fastening nuts K), 1-1 with circular knives , diameter, respectively, DI and DJ. fixed rigidly on the shaft 14 with the same 1 1 m distance between them, the feeding legs 15 and the packer rollers I) with the undercutting disc 17 and 17 but to the side pillars. Circular knives of 12 diameters of the diameter of the shaft but the edge of the shaft. G1 rollers 16 are additionally spring-loaded with springs 18. Obslenem and 1K) 1 Cyim pressure control of rollers 16 with undercut disks 17 on the ground. Feeding paws 15 with ko; 1sets (; pc) m-disperse. 1, 7 are connected by a flexible Hi.iiaHroM 19. Liquid fertilizers are supplied to the KOJi.iieKTOpy-distributor 7 via P1.; 1 ogovy feeder 20.

A device for fertilizer fertilization in the soil is mounted on the rear hitch of a tractor (not shown) with the help of a hinged device 4.

Disc blades 12 and 13 are driven into the ground by the mass of the device. With: first and recessed by the load from the manifold 7. The disc knives 12. having a smaller diameter DI, are buried to a smaller depth.

When the machine moves due to the torque generated by the friction forces on the contact surface of the soil and the disk knife 13, the latter begins to rotate at an angular speed

where V u is the linear velocity of the unit;

r - the radius of the rolling disk 13.

The disk knives 12 and 13. rigidly mounted on the shaft 14, have the same angular velocity UL3 and for equal periods of time at a fixed depth, they pass the same distance. The passage of disc knives 12 and 13 of the same distance is ensured by the different size of slippage of the disks 12 and 13.

Rolling disc knives 12 and 13c by slippage helps reduce the vertical force required for their penetration. Liquid fertilizers enter the slotted disc knives 12 and 13 through the feeding legs 15. Roller rollers 16, spring-loaded springs 18, pruning the wheels 17 cut the soil and move it from two sides to the very slot, blocking it. The supporting surface of the rollers 16 compacts the soil under- and slid to the slit, preventing splashing (release) of liquid fertilizers onto the soil surface.
