Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for fertilizing and sowing fertilizers and other bulk materials over the soil surface. Purpose of the invention

Description

nor - increase productivity and increase the width of seeding. The device consists of a row of sowing devices containing bunkers 8, mounted on racks 7, connected -. with hollow frame 1, which is connected to the fan by a hose. In the bunker, an inclined auger 9 with a rotor 10 is blocked by an axis 11 with radial pipes 12, which have articulated, adjustable guides 21 at the outlet. The rotor housing has a connection with a hose U 42108

the tank connected to the frame pipe, the air pressure from the fan rotates the rotor 10, which rotates the screw 9, which injects bulk materials through the cavity of the rotor hub 20. The mixture of air and bulk material through the radial pipes 12 is directed to the exit, where the guides 21, changing the direction of movement of the material, form a reactive action, contributing to the rotation of the radial pipes with the screw. 1 hp ff, 4 ill.

The invention relates to agricultural machinery, namely, machines for fertilizer application and for planting mineral fertilizers and other bulk materials on the soil surface.

The purpose of the invention is to increase productivity and increase the width of seeding.

FIG. 1 shows a device for seeding loose materials, Bi-y from above; - FIG. 2 - sowing unit, section} in FIG. 3 shows section A-A in FIG. 2; in fig. - section bb in fig. 2

The device for seeding loose materials consists of a frame 1 with a hollowed end with a casing 2 and support wheels 3, with which the hose 4 is rigidly connected to the fan 5 and the gearbox 6. having the ability to change the number of revolutions. On the Racks 7 are fixed bunker 8 sowing devices.

The inclined screw 9 with the rotor 10, the axis 11 is blocked with the radial pipes 12. The axis 11 to the bunker 8 is mounted on the bearing 13, and the lower part ends with a cone 14 connected centrally inside the radial pipes 12 having an inlet 15 with a bearing seat 16 which is fixed to the ring 17 in the groove of the inlet nozzle 15. The rotor housing 10 has a nozzle 18

with the hose 19, which is connected to the pipe frame 1,

The hub 20 of the rotor is rigidly seated on the turns of the auger. The radial pipes at the exit have pivotally connected adjustable guides 21,

The device works as follows. I

The fan 5 is driven from the tractor's PTO shaft through the gearbox 6 through the hose 4 to the hollow frame 1, and then through rods 19 to the rotors 10, the rotors lead the screws 9 to rotate, which are metered through the cavity of the hub 20 rotor bulk materials that are swirled with air flow are directed to radial rotating pipes 12; the mixture of air and bulk materials is directed to the outlets, where guides 21 change the direction of movement of materials that are scattered by ellipsoidal strips, Radial lines are inclined relative to the horizontal plane Direction .l guides 21, changed direction materi .0

form reactive action, contributing to the rotation of the radial nozzle with a screw.
