The purpose of the proposed design is to increase the spreading width and improve the distribution of fertilizers on the field surface.
The working body contains a frame 1, on which is the feed grinding drum 2, it is placed on the racks 3 knives 4 to separate a portion of fertilizer from the bulk. The drive of the grinding drum 2 is carried out by means of a chain transmission 5 from the sprocket 6 of the drive of the bottom conveyor 7. In front of the spreading bodies are installed guide trays 8. The spreading working bodies are rotors 9 consisting of disks with blades 10 spreaders. The discs have cutouts 11 for fertilizing nearby areas. The drive of the working bodies is carried out by means of a chain drive 12 through an intermediate shaft 13 with a safety clutch 14, gears 15 and cardan gears 16. For directional discharge of fertilizers, the disks are equipped with cutters 17.
The working body to the spreader of organic fertilizers works as follows. Fertilizers are fed by the bottom conveyor 7 to the grinding drum 2, which knives 4 separates portions of fertilizers from the bulk and feeds them on the guide trays 8 on the rotors 9. Part of the fertilizer, falling on the cutouts 11, cutters 17 are distributed across the width of the spreader portions of fertilizers and throw them at the required speed at a certain angle to the horizon.
Technical indicators:
- grip width – to 12 m;
- working speed – 10…15 km/h;
- application dose – 10…60 t/hа;
- uneven distribution of fertilizers – ± 22%;
- type of machine – trailer;
- type of machine – trailer – 2…4 ha/h;
- is aggregated with tractors of a traction class – 3.
