RU169547U1 - WORKING BODY FOR MISCELLANEOUS APPLICATION OF LIQUID FERTILIZERS - Google Patents

Abstract

The proposed device relates to agricultural machinery, and in particular to the working bodies for fertilizing. The working body for multi-level application of liquid fertilizers contains a rack with a divider and a chisel. On a rack knives with vertical slits are symmetrically installed. On the back of the knives fixed tubular fertilizers. Feeder tips at the ends of the tubular fertilizers are located above the vertical slots for supplying liquid fertilizers to the upper soil horizon. A tubular fertilizer is fixed on the back of the rack with a tip-feeder located behind the bit to supply liquid fertilizer to the lower soil horizon. The proposed utility model provides plants with nutrition during various periods of vegetation by means of a two-level supply of liquid fertilizers to the soil.

Description

The utility model relates to agricultural engineering, and in particular to the working bodies for fertilizing the soil when cultivating crops.

As a prototype, a working body for fertilizing was selected, containing a slit rack with a divider and a chisel, a knife with a fertilizer (Utility Model Patent No. 143494 RU IPC А01В 49/04, published on July 27, 2014).

The disadvantage of the prototype is the inability to supply fertilizers at different levels to the soil for plant nutrition during the growing season.

The technical task of the utility model is to provide the possibility of a two-level supply of liquid fertilizers to the soil to provide plants with nutrition during various periods of vegetation.

The technical result is ensured by the fact that the racks are symmetrically mounted on the rack with vertical gaps and with tubular fertilizers fixed to the rear with feeder tips at the ends located above the vertical gaps for feeding liquid fertilizers to the upper soil horizon, and a tubular fertilizer is fixed on the back of the rack with a feeding tip located behind the chisel for feeding liquid fertilizers to the lower soil horizon.

When fertilizers are applied to a shallow depth, they are used by plants only in the initial period of their development, but when the roots of the plants go to a greater depth, the fertilizers become inaccessible to the roots. When fertilizers are applied to a greater depth, plants begin to receive food late only with a fully developed root system.

In FIG. 1 shows a working body for multi-level application of liquid fertilizers, side view; in FIG. 2 - rear view; in FIG. 3 shows a section A-A.

The working body for the multi-level application of liquid fertilizers contains a rack 1 with a divider 2 and a chisel 3. On a rack 1, knives 4 with vertical slits 5 are mounted symmetrically. Knives 4 with a working width of b = 7 ... 13 cm are located at an angle. α = 30 ... 45 ° in the longitudinal-vertical plane relative to the horizon and with a solution angle of 60 ... 70 ° (not shown) at a height of a = 10 ... 15 cm from the level of the bit 3. Knives 4 have an upper sharpening β = 25 ... 35 ° and installed with a rear cutting angle γ = 5 ... 8 ° (Fig. 3). On the back of the knives 4 fixed tubular fertilizers 6 (Fig. 3). Feeder tips 7 at the ends of the tubular fertilizers 6 are located above the vertical slit-holes 5 for supplying liquid fertilizers to the upper soil horizon. Vertical crevice 5 with a height of c = 2 ... 5 cm are located at the ends of the knives 4. On the back of the rack 1 there is fixed a tubular fertilizer 8 with a tip-feeder 9 located behind chisel 3, for supplying liquid fertilizers to the lower soil horizon.

The working body for multilevel application of liquid fertilizers works as follows.

When the unit moves along the field, the working body for multi-level application of liquid fertilizers is buried in the soil. Stand 1 with a chisel 3 and knives 4 with vertical slits 5 loosen the soil and cut cracks in the soil at a specified depth. Liquid fertilizers through tubular fertilizers 6 are fed into the cracks cut by vertical slit 5 into the upper soil horizon, and through tubular fertilizers 8 into the bottom of the slot cut by chisel 3 into the lower soil horizon.

Doses for fertilizing the upper and lower horizons are set depending on the characteristics of cultivated crops.

The working body for multi-level application of liquid fertilizers can be used in the technology of strip tillage.

The proposed working body for multi-level application of liquid fertilizers provides plants with nutrition during various periods of vegetation by means of a two-level supply of liquid fertilizers to the soil.

Claims (1)
