Abstract

A seeding assembly in grain seeding machines, in which the position of some of the usual devices is modified and some others are redesigned, adding on the depth control device a hinge placed on the front part of the opener disks, which allows the angular opening of the depth control wheels with respect to the furrow opening disks, minimizing the entry of vegetable residues, dust, moist, soil, etc., and providing efficient and prompt cleaning of the existing space between the wheels and the disks, with the purpose of reducing detention time of the seeding 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 having on the front part of the assembly the articulation of the arms of a seeding depth control device with a mechanism, for example a hinge, which allows the angular movement of approach and separation of the depth control wheel with respect to the corresponding furrow opening disk.

2. Seeding assembly in seeding machines, according to claim 10, in which the hinge, on its closed position, allows the internal side face of the tire of the depth control wheel to be positioned at a minimum separation of the external side face of the corresponding furrow opening disk, maintaining such separation whatever the position of the wheel respect to the disk on its upwards or downwards movement is.

3. Seeding assembly, according to claim 10, characterized by the fact that the depth control wheel moves upwards and downwards on a plane parallel to the external side face of the corresponding furrow opener disk.

4. Seeding assembly, according to claim 10, characterized by the fact that the internal side faces of the mobile and fixed plates of the hinge are flat and, in closed position, parallel to each other, and these, in turn, are parallel to the external side face of the corresponding furrow opener disk.

5. Seeding assembly, according to claim 10, characterized by the fact that the shaft where the depth control wheel arm pivots is perpendicular to the internal flat side face of the mobile plate of the hinge.

6. The hinge of claim 11 characterized by the fact that on its closed position, the internal side face of the tire of the depth control wheel is positioned adjacent to the external side face of the corresponding furrow opener disk, at a minimum separation, and it is fixed by a lock, for example of the design indicated on FIG. 1, and on its open position, separates the depth control wheel of the corresponding furrow opener disk.

7. Seeding assembly, according to claim 10, in which regulation of the seeding depth is done operating, for example, a square—

threaded screw which articulated end operates on the levers attached to the arms of the corresponding depth control wheels.

8. The lock, according to claim 15, characterized by the fact that when operated manually releases the mobile plate of the hinge, in such a way that the depth control wheel attached to it pivots with increasing angle with respect to the furrow opening disk to enlarge the space between them, and with decreasing angle to place it close to the furrow opening disk, up to a final location in which it once again locks manually.
