Description

physical I

The invention relates to agricultural machinery, in particular, devices for applying liquid fertilizers to the soil in meadows and pastures.

The purpose of the invention is to simplify the design and increase reliability.

FIG. Figure 1 shows schematically an assembly, a section along its axis of rotation; in fig. 2 shows section A-A in FIG. one.

The assembly consists of a drum 1 with holes 2 and a hollow axis 3, a connecting pipe 4, curved knives 5 with grooves 6, a float 7 with flexible connections 8, a valve mechanism consisting of pressure bars 9 with valves 10, rods 11, springs 12, guides 13, support wheels 14, and also from bearings 15 of the drum fastening assembly to the frame of the trailed (attached) device (not shown).

The unit works as follows.

Drum 1 using connective

In operation, the drum 1 is constantly filled with liquid fertilizers, therefore the buoyant force acting on the float 7, through flexible couplings 8 and rods 11, compresses the springs 12 of the lower pressure plates 9, overcomes the hydrostatic pressure, lifts the valves 10 and opens the holes 2 at the bottom of the drum 1. Liquid fertilizer through holes 2 flow into the grooves 6 curved knives 5 and

10 they flow down into the slots cut by knives. Thus, simultaneously with the formation of gaps, they are filled with liquid fertilizers.

Upon further rolling of the drum 1 due to the eccentricity of the position of the axis of the float 7 relative to the axis of the drum 1, the effect of the flexible links 8 is weakened and under the action of the springs 12 the pressure bars 9 are mixed in the direction of the lower 13, closing the valve nozzle 4 to the tank 10. - 20 2. The position of the float 7 is adjustable

These fertilizers (not shown) are filled with them and simultaneously with the tractor, through a trailed (attached) device, move across the field. When the drum 1 rolls across the field, the knives 5 cut through the slit in the turf, and due to the curvilinear shape of the knives, the soil is pushed down and to the sides, forming a low swelling and not forming soil rollers. The knives 5 are directed by the convex side in the course of the rotation of the drum 1, therefore simultaneously with the process of attention of the soil down and to the sides it is cut, due to which the quality of the slots is improved. At the same time, the grooves 6 in the knives 5 and the holes 2 in the drum are protected from clogging the soil, since they are located on the opposite side of the knives 5 along the cutting direction. The support wheels 14 regulate the depth of the knives 5 into the soil, thereby protecting the grooves 6 and the holes 2 from clogging with soil. In addition, the support wheels 14 prevent

changing the length of the flexible couplings 8 in such a way that the valves begin to open at the moment the knives 5 enter the soil and close at the moment they leave it. At the same time, liquid fertilizers fall only into the cut-through slots and do not contaminate the surrounding plants. The curvilinear shape of the knives 5 prevents the holes 2 from clogging the soil.

Invention Formula A unit for introducing liquid fertilizer into the soil, which contains a drum with holes and working tools with grooves installed in a staggered manner on its case, an exhaust valve mechanism, characterized in that, in order to simplify the design and increase reliability of operation, it is equipped with a float connected by flexible connections with the exhaust valve mechanism, the working bodies are made in the form of knives to the rolling wheel of drum 1 across the field of its entire 40 linear form, with knives that are convex; It is completely filled with liquid fertilizers, therefore the buoyant force acting on the float 7, through flexible couplings 8 and rods 11, compresses the springs 12 of the lower pressure bars 9, overcomes the force of hydrostatic pressure, raises the valves 10 and opens the holes 2 in the lower part of the drum 1. Liquid fertilizer through holes 2 flow into the grooves 6 curved knives 5 and 0 they flow into the slits cut by knives. Thus, simultaneously with the formation of gaps, they are filled with liquid fertilizers.

The position of the float 7 is adjustable changing the length of the flexible couplings 8 in such a way that the valves begin to open at the moment the knives 5 enter the soil and close at the moment they exit from it. At the same time, liquid fertilizers fall only into the cut-through slots and do not contaminate the surrounding plants. The curvilinear shape of the knives 5 prevents the holes 2 from clogging the soil.
