Description

The invention relates to agricultural machinery, in particular to means for. The introduction of mineral fertilizers on the soil surface.

Fertilizers can be introduced into the soil by adjacent flows laid on its surface parallel to each other.

However, in this case, fertilizers are distributed unevenly over the soil surface.

A device is known by which fertilizers are applied in this way. This device contains mounted on the support of the sowing body in the form of a trellis plate with a drive mechanism for its reciprocating movement.

However, the device does not provide an even distribution of fertilizers across the soil, since the sowing body is made in the form of a trellis plate, moving back and forth periodically opening the sowing holes.

The purpose of the invention is to increase the uniformity of the distribution of fertilizers on the soil surface.

This goal is achieved by the fact that fertilizers are applied to the soil surface in intersecting directions in the form of a grid. The method of forming such a trace of fertilizers on the soil is that adjacent flows of applied fertilizers are directed along a zigzag path, and the flows are shifted one relative to the other by a half period.

B. device for implementation. of the proposed method of fertilizing that is mounted on a support, a sowing body with a drive mechanism, located under the sowing holes of the distribution body, is made in the form of front and rear planks installed by means of rollers on the support, and is equipped with funnel-shaped grooves located above the sowing body, with sowing nozzles, moreover sowing nozzles are fixed in the holes of the slats, and longitudinal grooves are made in the support for moving the ends of the sowing nozzles in them.

Figure 1 shows the trace of fertilizers formed by known structures; Fig. 2 is a trace of fertilizers formed by the proposed design, Via Fig. C is the trajectory of the working bodies in motion; figure 4 is a device, a longitudinal section; figure 5 is a section. AA in figure 4; FIG. 6 is a section B-E in FIG. 4'.

The method of applying mineral fertilizers is carried out by changing the direction of adjacent flows along a zigzag path, and the flows are shifted one relative to the other by a half-period. Such a trajectory of fertilizer flows is formed when two types of movement are combined — this is the forward movement of the aggregate and the simultaneous oncoming reciprocating motion of the spreading working bodies in the direction transverse to the aggregate movement (Fig. 3).

As a result of the combination of the movements of the aggregate and the spreading working bodies, a trace of fertilizers is formed on the soil surface in the directions intersecting each other, in the form of a grid (Fig. 2),

The method is carried out using a device containing a storage hopper 1 with a conveyor 2 for feeding fertilizer — to a distributor — a device consisting of a screw 3, driven by a shaft 4 by means of a worm gear, and a groove 5 located under the screw, along the screw, and in the same.

Under the groove 5 there is a sowing body made in the form of a front 7 and a back 8 plates resting 4th on a support 9 by means of rollers (balls, forges) 10. The front and rear plates are equipped with funnel-shaped grooves 11 with sowing nozzles 12 arranged in a row, Sowing -th nozzles 45 are fixed in the holes 13 of the plates and are located in the longitudinal grooves 14 of the support 9. The plate 7 is equipped with a drive 15 made in the form of a crank mechanism, movable 50 plates 7 and 8 are installed across the direction of movement of the unit; ' in the same direction they carry out oscillatory (reciprocating) movements.

Each of the adjacent sides of the plaza. type 7 and 8 is equipped with a longitudinal gear plate, which is constantly engaged with gears 16, This gearing allows you to transmit a momentum from the front plate 7 to the rear plate 8 through gears 16, and the direction of the transmitted movement is the opposite, So, each of the plates 7 and. 8 is provided with a reciprocating drive, and in the opposite direction to each other.

The device operates as follows. ·
