Abstract

A seeding assembly in grain seeding machines, in which the position of the elements is modified and some of them are redesigned; which includes an articulation hinge kind of mechanism in association with the seeding movement, minimizing the entry of vegetable residues, dust, moist soil, etc., simplifying release thereof, and providing efficient and prompt cleaning with the purpose of reducing detention time of the machine.

Claims

1. Seeding assembly in seeding machines including:

a. A device for furrow opening

b. A device for directing the seed into the furrow

c. A device for directing the fertilizer into the furrow

d. A device to control the depth of seeding

e. A device for furrow closing

f. A device to press the seed

characterized by being arranged in a position that provides higher efficiency of the depth control function, where regulation depends on a screw bolt that operates a lever attached to the arm of the depth control wheel, which in turn may swing in a hinge kind of mechanism, located in the front of the assembly.

2. Seeding assembly in seeding machines, according to claim 1, characterized by the fact that the hinge kind of mechanism, located in the front part, includes flat faces in both its articulated plates located parallel to the flat face of the respective furrow opening disk, being also a mobile plate and a fixed plate in reference to the balance beam.

3. Seeding assembly in seeding machines, according to claim 2, characterized by the fact that the hinge kind of mechanism, located in the front, includes attached to its mobile articulated plate a shaft where the arm of the depth control wheel swings, placed in such a way that whatever the regulation depth, the flat side face of the wheel is always separated by the same minimum distance from the corresponding furrow opening disk, since upward or downward movement thereof is parallel to the side face of the disk.

4. Seeding assembly in seeding machines, according to claim 3, characterized by including a manual locking mechanism on each side of the outer side faces of the balance beam, which fixes to its operative position the hinge kind of mechanism corresponding to each depth control wheel, operating the respective mobile articulated plate.

5. Seeding assembly in seeding machines, according to claim 4, characterized by the fact that the hinge kind of mechanism is arranged in the front of the assembly, joining the fixed articulated plate to the balance beam by a piece designed for said purpose.

6. Seeding assembly in seeding machines, according to claim 5, in which the depth regulation and articulation of the hinge mechanism is arranged in the front part of the assembly, in such a way that the forces produced by the seeding movement tend to press the depth control wheel against the furrow opening disk.

7. Seeding assembly in seeding machines, according to claim 6, in which regulation of the depth control wheel depends on a screw bolt located over the balance beam, which operates an articulated end, the side parts of which press or free the levers attached to the arms of the corresponding wheels, thus controlling the penetration depth of the furrow opening disks and providing free and separate movement to the wheels.

8. Seeding assembly in seeding machines, according to the foregoing claims, characterized by the fact that the hinge kind of mechanism is manually released by operating the lock, in such a way that the depth control wheel may swing with increasing angle respect to the furrow opening disk, to clean and/or repair, and with decreasing angle to place it close to the furrow opening disk, up to a final location in which it once more locks manually.

9. Seeding assembly in seeding machines, characterized by the fact that it is described by the foregoing claims and, without limitations, it is in line with the specification and drawings herein attached.
