ROD FOR ADDING DUSTY FERTILIZERS

one

The invention relates to the field of agricultural mai ostroyiei, in part to maiiam for applying dusting fertilizers.

Known rods for applying pulverized fertilizers, including a conical tube with outlet openings and end clamps for removal of grain and inclusions of fertilizers and other irimesis, do not provide the required uniformity of fertilizer distribution on the surface of the night, which is caused by an increased density of fertilizer flow and forming the first in the rubble.

In order to eliminate the noted deficiency, a longitudinal axis was installed in the conical tube in the proposed tube; the partition wall was divided into two parts, the lower part of which was supplied with compressed air, and the upper part had the aerated fertilizers. At the top of the pipe, air outlets can be made with air filters installed in them.

Figure 1 shows the representation of the Itanga.

The rod consists of a conical tube 1, divided by a longitudinal porous partition 2 and two parts: the bottom 5 with a pipe 4 for supplying compressed air and the top 5 with a pipe 6 for feeding pre-aerated fertilizers. In the upper part of the ko: -; the pipe has holes 7 molded; che;) €;; the material is output, 1. the outside and the cross section of which is controlled by uuiTi: o.M 8, and also windows 9 with uTetan in iMi.x filters 0 to release the excess: part of air.

The end opening of the upper part of the conical pipe is blocked by a valve // with a drive, nanr |; msr, from hydrochiller J2 with a distance of 10;

The work of HiTaiini is as follows.

Some part of the air, thanks to a small increase in the resistance of the filters 10. 51 1 goes out, intensively mixing

5 fertilizers over the fence 2 and lowering the density of aurirovapnogo flow. This eliminates the formation of debris and contributes to the paiiomeriod1 at the expiration of the air mixture through the outlet openings. In addition, a part of the air, you will see through the filter 1 10, and will not participate in

transporting reruns broke: y, which reduces their dusting.

When large impurities of fertilizers accumulate in the rod that cannot pass through the outlets and clog them, the operator, without stopping the unit, opens the valve using hydraulic cylinder 12 //. Under the influence of air pressure, solid inclusions are thrown out.
