Description

I

The invention relates to agricultural machinery, namely, the construction of raspberries for sowing seed materials (mineral fertilizers, granular herbicides, grains, etc.) both in surface sieving and in soil application.

The aim of the invention is to reduce the dimensions of the guide tube and to improve the uniform distribution of the material along the material lines.

1 shows a schematic side view of a machine; figure 2 - section aa in figure 2; 1) ig.3 - view B in figure 1; Fig. 4 shows a tukonapoditel with axons of funnels.

The pneumatic windrow consists of a hopper with a feeder 2, a fuser guide 3, divided by longitudinal barriers 4 into channels 5, the number of which corresponds to the number of material pipes 6. The channels in the lower part of the fuser guide are connected to funnels 7 with exhaust ports 8, communicated with the inner ends pipelines 6, which are connected at the point of reception of the material through ejectors 9 and air lines 10 with a source of compressed air (not shown).

the holes 8 are located on the sides

 on the longitudinal plane of symmetry of the tukonapoditel, and the top is on the backside;

Selka works as follows.

Sowing material from bunke1) d. I is fed by power supply 2 to the driver O 3, where it is divided into equal parts by the bulkheads 4 and moves along channels 5 to the funnels 7 with outlets 8 and through them enters the

(5 The ends of the material lines 6, in which air flow from the compressed air source is pulled up and transported to the places of entry into the soil.

20 Thus, due to the location of the outlet openings 8 on the sides of the angle, the bisector of which lies in the longitudinal symmetry plane of the tube guide, at the top 25 on the back wall of the middle funnel, the distance between the longitudinal axes of the material pipes decreases, which reduces the longitudinal dimensions of the tuft core and increases uniformity

30 of the distribution of material through the material pipelines due to an increase in the angles of inclination of the pitched walls of the funnels of the guide tube to the horizon.
