Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, machines for the subsoil application of solid mineral fertilizers.

The purpose of the invention is to increase the reliability of the technological process and improve the quality of embedding fertilizers in the soil by increasing the distance between rows of embedding, their working bodies.

Figure 1 shows a machine for intra-soil application of solid mineral fertilizers, side view; figure 2 is the same, rear view; on fig.Z - section aa in figure 2.

The machine for the soil fertilization of solid mineral fertilizers contains a frame 1 (Fig. 1) mounted on the traveling wheels 2, on which is fixed a hopper 3 with a feeder. The frame 1 is hinged to the left and to the right of sections 4 and 5 with supporting wheels 6. Each section has two covers 7 and 8, joined in the lower part and on the top closed with a flat cover. A feed screw 9 is installed inside the casing 7, and a return screw 10 is installed in the casing 8. The feed screw 9 is intended for transporting fertilizers from the bunker 3 across the width of the machine, the return screw 10 for return transportation to the bunker. Between the screws 9 and 10, a vertical partition 11 is installed, at the ends of which reloading windows 12 are made, the junction covers 7 and 8 are connected. The casing 7 of the feeding screw 9 has in its upper part a loading window 13 (FIG. 2). The latter through a flexible pipe 14 is connected to the unloading window 15 of the hopper 3. In the lower part of the housings 7 and 8, the outlet windows 6 are made, and they have sowing devices 17 connected through tukoprovoda 18 to the sealing working elements 19. Moreover, the sowing devices of the feed screw 9 are connected with laterally mounted organs 19 installed in the transverse direction in the rear row, which is placed under the feeding screw 9. The seeding devices of the return auger 10 are connected to the closing working elements 19 that are installed in the transverse direction The pressure in the front row, which is located beneath the return auger. Front in the direction of movement of the machine can be set as feed

auger and returnable.

The drive of the sowing apparatus 17 and the screws 9 and 10 is made from the traveling wheels. Moreover, the screws 10 of sections 4 and 5 are connected with the drive through universal joints 20 and 21, which ensure the transmission of steeper moment at the hinged connection of sections 4 and 5 with the frame 1 of the machine.

The machine works as follows. Before the machine starts working, the embedding working bodies are adjusted to the required depth of fertilizer application, and the sowing apparatuses - at a given seeding rate. After that, the fertilizer is loaded into the hopper. Fertilizers from the hopper 3 are fed by the feeder through the discharge port 15 to the flexible pipe 14, from which they are sent through

the loading window 13 into the casing 7 is caught by the turns of the screw 9 and transported along the casing 7 along the width of the machine grip. At the same time, the required amount of fertilizers is sown from the casing 7 sown, by their devices 17 into the pipeline 18, arriving at

closing pads 19 rear p. Not all the fertilizers from the casing 7 are mixed to the end of this casing, after which the unloading end of the screw 9 is thrown through the window 12 into the casing 8. In the latter they are caught by the loading end of the screw 10 and transported in the opposite direction along the casing 8. The fertilizers from the casing 8 are sown vehicles 17 into the pipeline 18, and from them come to the embedding working bodies 19 front

p yes Working bodies 19 fertilize the soil to a predetermined depth.

Fertilizers that have not been evacuated from the casing 8 are mixed up to the discharge end of the screw 10. After that, they are transferred by the screw 10 from the casing 8 through the reloading port 12 into the casing 7 to the auger loaded from the hopper, the loading end of the screw 9, where again captured last, i.e., the chain of movement of the material in shells 7 and 8 is closed.
