COMBINED FERTILIZER APPLYING AND SEEDING MACHINE Russian patent published in 1994 - IPC

FIELD: agricultural engineering. SUBSTANCE: machine has fertilizer doser 4 disposed in lower part of fertilizer hopper 3 and seed doser 9 disposed in lower part of seed hopper 8, which are provided with cells arranged over surfaces of dosers 4 and 9 in apexes of equilateral triangles. Chain drive 16 is positioned between dosers 4 and 9. Receptacles 5 made in the form of hollow tubes have upper ends connected with bottom of hopper 3 and aligned along straight line extending in parallel with axis of doser 4. Axes of receptacles 5 are disposed in planes of cross-sections of doser 4, with cross- sections being drawn through axes of cells, and at an angle one with respect to the other. The number of receptacles 5 is equal to that of planes of cross-sections of doser 4 drawn through cell axes. Receptacles 10 made in the form of hollow tubes have upper ends connected with bottom of hopper 8 and disposed in alignment along straight line extending in parallel with axis of doser 9. Axes of receptacles 10 are disposed in planes of cross-sections of doser 9 drawn through axes of cells having equal areas of bases at an angle one with respect to the other. The number of receptacles 10 is equal to that of receptacles 5. Fertilizer shoes 6 and seed shoes 11 are fixed to frame 1, with the number of shoes 6 and 11 being equal to that of receptacles 5 and 10. Shoes 11 are disposed on higher level than shoes 6. Coverers 7 are attached behind shoes 6, coverers 12 are fixed behind shoes 11. The number of coverers 7 and 12 is equal to that of shoes 6 and 11. Coverers 12 are disposed on level higher than coverers 7, which are positioned on the level higher than shes 6. Coverers 12 are positioned on the level higher than shoes 11. In the process of travel of machine shaft of rear wheels 15 drives dosers 4 and 9 into rotation to provide feeding of fertilizer from hopper 3 through doser 4 into receptacles 5 and through receptacles 5 onto furrow bottom by means of shoes 6, which cut these furrows, with fertilizer doses being dropped into furrows and disposed in apexes of equilateral triangles. Coverers cover fertilizer doses with soil layer having the thickness of 1-2 cm. Simultaneously doser 9 withdraws seeds one-by-one from hopper 8 into cells, from which seeds are delivered through receptacles 10 precisely onto soil covered fertilizer doses by means of shoes 11. Coverers 12 cover seeds with layer of soil. EFFECT: increased yield and simplified construction of machine. 9 cl, 4 dwg
