DETAILED DESCRIPTION
OVERVIEW [0026] Referring now to the drawings, in which the same reference numbers designate identical or corresponding parts through the different views, Figure 1 is a perspective view of an agricultural row unit 10. The row unit 10 is attached to a toolbar pulled by a tractor by a mounting assembly 20, which preferably comprises a set of parallel arms that articulate a front support 28 to a rear support 26 (Figure 2). The row unit 10 preferably includes a counter set 40, a depth adjustment set 60, sets of calibration wheels 50, sets of seed tubes 100, sets of opener disc 200 (Figure 2), and a set of closing 30. Row unit 10 preferably also includes a motor mounted on row unit 70.
[0027] Referring to Figures 2 and 6, the counter assembly 40 includes a first counter 42-1 and a second counter 42-2 supported by a counter structure 46 on the row unit 10. As best illustrated in Figure 4, the opener disk assemblies 200 each open a separate ditch in the ground disposed under each counter 42. Each
Petition 870180065772, of 07/30/2018, p. 13/32
The counter can comprise any measuring device adapted to distribute the crop inputs. In some embodiments, seed counters 42 comprise vacuum type seed counters. The motor 70 is preferably adapted to drive the counters 42 through a mechanical connection (not shown) with skin minus one of the counters; the operation of the counters 42 is preferably connected by a mechanical connection (not shown) such as an axis connecting the seed disks of the counters. In other embodiments, motor 70 is replaced by another counter drive mechanism such as a hydraulic drive or a ground drive; in some embodiments, the counter drive mechanism is mounted on the toolbar that pulls the row unit 10.
[0028] As best illustrated in Figures 4, 5 and 7, the row unit 10 includes mounting plates 300 attached to the rear support 26. Each seed tube assembly 100 is mounted on the mounting plate 300 associated with a mounting support 310. As best illustrated in Figures 8 and 9, each mounting plate 300 includes a downwardly extending portion 330 on which each open disc assembly 200 is mounted by a threaded shoulder 230.
[0029] Looking at Figure 6, each seed tube set 100 includes a seed tube 150 that defines a seed path from each seed counter 42 to the ditch created by the associated opening disc set 200. Each seed tube assembly 100 preferably includes a seed tube guard 110 mounted in the downward extending portion 330. The seed tube guard 110 preferably extends under the seed tube 150 to protect the seed tube 150 from contact with the ground. The seed tube guard 110 preferably extends to each side of the seed tube 150 to protect the seed tube 150 from contact with the
Petition 870180065772, of 07/30/2018, p. 14/32
5/12 opener disc set 200. Closing set 30 includes closing wheels 35 arranged behind each seed tube 150 and configured to close the ditch created by the associated opener disc set (Figure 3).
[0030] In operation, as the planter crosses the field, counters 42 deposit the seeds through the seed tubes 150 into the open ditch by the associated opener disk set 200. The associated closing wheel 35 then closes the ditch. [0031] The depth of the ditches created by the opener disc sets 200 is adjusted by the height of the calibration wheel sets 50 (Figure 1) in relation to the opener disc sets 200. As best illustrated in Figure 2, each set of calibration wheel sets The calibration wheel 50 includes a calibration wheel 52 hinged on a calibration wheel arm 55. The calibration wheel arm 55 is preferably mounted hinged on row unit 10 around a hinge 57. The calibration wheel arm 55 includes a depth adjustment portion 62. The depth adjustment portion 62 extends through an opening 320 (Figure 4) in the mounting plate 300. As best illustrated in Figure 3, the height of the depth adjustment portions 62-1 62-2 of the calibration wheel arm assemblies 50 are bounded lower by a rocker arm 63 hinged to the row unit 10.
[0032] In operation, the calibration wheels 52 couple rollers to the ground and each set of opener disc 200 opens a trench that has a depth equal to the vertical displacement between the bottom of the calibration wheel 52 and the bottom of the opener disc set 200 associated. The vertical displacement is adjusted by the vertical position of the rocker 63, which can preferably be adjusted using an adjustment arm 65 (Figure 2). When, for example, the right 52-1 calibration wheel encounters an obstruction or change in terrain that forces the
Petition 870180065772, of 07/30/2018, p. 15/32
6/12 right calibration upwards, the right calibration wheel arm 55-1 will rotate clockwise around joint 57 (as seen from the perspective of Figure 2), forcing rocker 63 to articulate and thus forcing the other calibration wheel arm 55-2 to rotate and move the calibration wheel 52-2 downwards. It should be appreciated that when a first calibration order 52 encounters an obstruction that requires the calibration wheel to rise by a height H in relation to the ground, the second calibration wheel will lower by a height H / 2 to lift the entire row unit by H / 2 so that the first calibration wheel only needs to lift by H / 2. Thus, incorporating the rocker 63, the depth adjustment set 60 advantageously divides the vertical displacement of the row unit 10 caused by each obstruction by a factor of two.
[0033] The closing wheel assembly 30 preferably includes a downward pressure adjustment arm 32 that allows a user to adjust the downward pressure on the closing wheels 30 as described in US Patent Number 5,676,073, the description of which is hereby incorporated in its entirety by reference.
[0034] The illustrated modalities of row unit 10 described here include two sets of counters 42, sets of opener disc 200 and sets of seed tubes 100 attached to a tool bar by a single assembly set 20. This is advantageous for narrow row applications, as well as double row applications in which the seeds deposited by counters 42-1 and 422 are timed in order to obtain a checkerboard pattern as described in US Patent Application Serial Number 12 / 645,789, the description which is hereby incorporated in its entirety by reference. However, in other modalities a single counter, set of open disc and set of seed tube are included in row unit 10. In such modalities the spacing between the
Petition 870180065772, of 07/30/2018, p. 16/32
7/12 rows is determined by the cross-spacing of individual row units 10 along the toolbar. In such embodiments, a single closing wheel 35 preferably follows the seed tube assembly.
OPENING DISK SETS [0035] Referring to Figures 8, 10A and 10B, each open disk set 200 includes an outer disk 210 and an inner disk 220. The outer disk 210 and inner disk 220 are preferably adjacent to each other. The outer disk 210 includes a support housing 217 which rotates around a spike 215. The spike 215 is received within a threaded cavity 216 (compare Figure 11A with Figure 11B) within the threaded support 230. Thus the disk outer 210 rotates about a geometric axis defined by the orientation of the spike 215. The internal disc 220 includes a support housing 227 which rotates around a spike 225. The spike 225 is received within a threaded cavity 226 (compare Figure 11A with Figure 11B) inside the threaded support 230. Thus the inner disk 220 rotates around a geometric axis defined by the spike 225.
[0036] It should be appreciated in the light of this description that the relative orientation of the opening discs 210, 220, defines the dimensions of the trench created by the opening disc set 200. As best illustrated in Figures 10A and 10B, in a preferred embodiment, the disc internal 220 is oriented vertically with respect to the ground. In other words, the geometric axis of rotation of the inner disk 220 is preferably oriented horizontally with respect to the ground.
[0037] As best illustrated in Figure 11A, the outer disk 210 contacts the inner disk 220 in a contact area close to a perimeter of the inner disk and close to a perimeter of the outer disk. It should be appreciated that as the discs 210, 220 rotate, the contact area remains in the same location. External disk 210 is
Petition 870180065772, of 07/30/2018, p. 17/32
8/12 displaced from internal disk 220 by an AV offset angle. As the AV angle is increased, the angle of the ditch 1500 (Figure 14B) opened by the open disc assembly 200 increases. In a preferred embodiment, the AV angle is 10 degrees.
[0038] Figure 12A illustrates the AV angle schematically as determined by the angle between a geometric axis 228 defined by the spike 225 and a geometric axis 218 defined by the spike 215. Figure 12B is seen from the side of the outer disk 210 along the geometric axis 228. As seen in Figure 12B, the geometric axis 218 of the spike 215 can be adjusted along the direction indicated by the arrow A. This adjustment controls the location of the contact point between the discs 210, 220. [0039] As illustrated in the Figures 12B and 13, the geometric axis 218 is on a plane 219 that intersects the contact area between the discs and the ground. The 219 plane is at an AH angle from the horizontal. Since a preferred AV angle is adjusted between the discs to a desired ditch angle, the orientation of the axis 218 is preferably adjusted as shown in Figure 12B to obtain the desired AH angle. The angle AH is preferably chosen so that the discs 210, 220 enter the ground at approximately the contact area between the discs; it should be appreciated that the disks enter the ground in an area in front of the centers of the disks 210, 220. In a preferred embodiment, the angle AH is 45 degrees.
OPENING DISCS [0040] As illustrated in Figure 8 and Figures 10A-11B, in modalities in which the internal disk 220 is substantially vertical, the internal disk preferably includes a chamfer 222 around or near the perimeter of the disk. Chamfer 222 improves the ability of the inner disk 220 to penetrate the ground.
[0041] In a preferred embodiment, the face of chamfer 222 is oriented in the direction of external disk 212. This chamfer orientation
Petition 870180065772, of 07/30/2018, p. 18/32
9/12
222 is beneficial specifically in embodiments in which two sets of opener discs are mounted next to each other, such as in double row applications. As illustrated in Figures 16A and 16B, in a double row mode a distance D between the internal discs 220 can be approximately 152.4 mm (six inches). Under such circumstances, if the chamfers 222 face each other as shown in Figure 16B, the soil 1410 can be gripped between the inner disks 220 and pulled upward as the row unit 10 crosses the field. This result occurs in the modality shown in Figure 16B because the soil is compressed as the internal discs 220 first penetrate the soil 1410 at a front edge and then progressively push the soil further inward. In the preferred embodiment illustrated in Figure 16A, the chamfer still helps with soil penetration, but does not cause compression within the soil 1410.
[0042] Even in modalities in which the distance D is greater (for example, 762 mm (thirty inches)), it is still advantageous that the chamfer 222 faces away from the ground contacted by the face of the inner disk 220 this is because the side wall 1430 created by the inner disk 220 can become cut by the increased pressure between the ground and the inner disk if chamfer 222 is oriented towards the face face 1430. [0043] The outer disk 210 preferably also includes a chamfer 212, of preferably oriented away from the internal disk 220. Ditch formation [0044] As row unit 10 crosses the field, the row unit creates and closes a ditch 1500 on the ground 1410 as best illustrated in Figures 14A-14C and 15. opener disc assembly 200 penetrates the soil 1410, the calibration wheel 52 compresses the soil adjacent to the outer disk 210 while maintaining the appropriate trench depth. The seed tube set 100 preferably
Petition 870180065772, of 07/30/2018, p. 19/32
10/12 includes a fertilizer knife 120 mounted on the seed tube guard 110 and configured to cut a cavity 1440 within the soil adjacent to a gutter 1405 of the Veleta 1500.
[0045] The trench 1500 created by the opening discs is best illustrated in Figure 14B. External discs 210 create an inclined sidewall 1420 in the ground. The inner discs 220 create a substantially vertical sidewall 1430 on the ground. Trench 1500 includes a trough 1405, where a seed 1400 is preferably deposited after the trench is opened. The excess soil 1415 removed to form the ditch 1500 is preferably deposited adjacent to the outer disk 210. The soil 1425 adjacent to the inclined side wall 1420 is compacted due to the load imposed by the calibration wheel 52. The soil adjacent to the vertical side wall 1430 it is not substantially compacted by the operation of row unit 10. A liquid applicator (not shown) mounted on the seed tube assembly 100 preferably injects a fertilizer or other liquid or crop input into or near cavity 1440 created by the knife fertilizer 120. The cavity 1440 preferably extends into the relatively loose soil 1435 because the seedling roots of the seed 1400 will tend to grow away from the compacted soil 1425 and towards the relatively loose soil. Thus, the fertilizer knife 120 preferably extends downwards and away from the outer disk 210.
[0046] After seed 1400 and any liquid fertilizer have been placed, closing wheel 35 presses all or a portion of excess soil 1415 back into ditch 1500, covering seed 1400 as illustrated in Figure 14C. Although the closing wheel 35 further compacts the soil 1425, the soil 1435 adjacent to the inner disk 220 remains relatively loose.
[0047] Fertilizer or other liquids can be deposited on the soil after the ditch is closed as shown in Figure 15. A nozzle
Petition 870180065772, of 07/30/2018, p. 20/32
11/12 of applicator 1550 preferably deposits the soil on top of the relatively loose soil 1435 because the seedling roots of the seed 1400 will tend to grow away from the compacted soil 1425 and towards the relatively loose soil. Thus the applicator 1550 is preferably mounted on the inner side of the inner disk 220, that is, opposite the outer disk 210 on the closing assembly 30 as shown in Figure 3. ROW CLEANERS [0048] As illustrated in Figure 17, a set row cleaner 1700 may preferably be incorporated into row unit 10. The row cleaner set 1700 may include a single row cleaner 1710 in front of each opener disc assembly 200. Each row cleaner 1710 preferably comprises a row cleaner arm 1730 having a first end and a second end. The first end of the row cleaner arm 1730 is preferably pivotally mounted on the row unit 10 to pivot about a geometric axis substantially transverse to the direction of travel. A soil coupling blade 1720 is preferably mounted hinged on the second end of the row cleaner arm 1730. The soil coupling blade 1720 associated with the row cleaner 1710 is preferably oriented at an angle with respect to the direction of travel and preferably extends across the area to be opened by the open disc assemblies 200 so as to clear debris and crop residues from the path of the open disc assemblies.
[0049] The above description is presented to allow someone skilled in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications of the preferred mode of the apparatus, and the general principles and characteristics of the system and methods described here will be readily apparent to
