(5A) WORKING BODY FOR SCATTERING OF DUSTY FERTILIZERS

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for applying fertilizer by means of distributing itang.

A known machine for applying dust fertilizers, which includes a container for the material, a pump and a horizontal distribution pipe with evenly spaced holes along the length - Q m til.

This device does not provide the required quality of fertilizer distribution over the soil surface due to the 5 blocked outlets of impurities.

Closest to the invention is a working body for sowing pulverized fertilizers, including 20-pant trousers, made in the form of a pipeline with sowing holes evenly spaced along its length, to which the cages are connected. .

A disadvantage of this device is the great laboriousness of changing the dosing nozzles when changing the seeding rate and the low technological reliability of the application process, since the particles of fertilizers accumulate in the protrusions of the rods and the dosing nozzles and prevent the expiration process.

The purpose of the invention is to improve serviceability and productivity when changing the seeding rate.

Claims (2)

The goal is achieved by the fact that additional holes are made in the pipeline along its longitudinal axis, support plates are installed between the nozzles and sowing holes, and plates with tapered projections with holes of different sizes are placed in the additional holes the pipelines and the conical protrusions of the washers into the holes and cavities of the support plates. FIG. 1 shows a machine in plan view; in fig. 2 is a view along arrow in FIG. 1. A working body for sowing fertilizers includes a rod 1, which is made in the form of a pipeline with sowing holes evenly spaced along its length 2. Nozzles 3 are connected to the holes 2. In the pipeline along its longitudinal axis, additional holes Ts are made. and with sowing holes 2, there are installed holes 5 and conical hollow protrusions 6 supporting plates 7 and having tapered projections (With 9 holes of different-sized washers 10. Projections 6 of supporting plates 7 are marked in additional holes i The water and the conical BM of the stupa 8 of the washer 10 are in the holes 5 and the cavities of the supporting plates 7. The horizontal surfaces 11 of the conical projections 8 of the washers 10 are located at the level of the inner surface 12. The dosing nozzles 3 are pressed by the funnel 13 and fixed by clamp 1A. The organ is connected to a tank 15 having a source of compressed air 16 and is transported by an aggregating device 17. The working organ operates as follows. Fertilizers from the tank 15 due to the aeration of the material and the air pressure supplied from the compressed air supply air 16 are fed into the rod 1. Under the action of overpressure, the aerated material moves through the pipeline and flows out through the sowing holes 2 into the holes 5 and 9. Flow rod fertilizer depends on the diameter of the hole 9 in the protrusions of the washers 1 (T To change the dose, it is enough to release the clamp 1 and combine another protrusion of the washer 10 having a different hole size 9 with the through hole of the pipe 9. Due to the presence of the projections 8 on the washer 10, ensure Their precise fixing in the support plates 7 and the conical shape with the selected parameters provides a tight fit and ease of installation, avoiding jamming in the holes of the support plate 7 of the rod 1. The horizontal surface 11 of the conical protrusions 8 at the level of the inner surface 12 of the pipe eliminates the possibility of accumulation large particles of material & la and clogging of the holes, as large inclusions slip along the surface 11 of the protrusion 8 of the washer 10 and are transported to the end of the pipe, where it is easy to remove TC when cleaning at the end of the process of sieving material. This ensures the stability of the fertilizer application process. The implementation of the proposed machine allows to increase productivity by 15-20 and improve the quality of fertilizer application. The invention of the working body for sifting pulverized fertilizers, including a rod, made in the form of a pipeline with evenly spaced along its length, sowing holes, to which nozzles are connected, in order to improve serviceability and productivity when changing the seeding rate, in the pipeline along its longitudinal axis, additional holes are made; between the nozzles and sowing holes, there are support plates with openings and conical hollow protrusions, as well as having onicheskie protrusions with different-sized apertures washers, wherein the bearing surfaces of the projections are arranged in the additional conduit apertures, and conical protrusions Washers - in the holes and cavities of the support plates.
