Abstract
Description
[0100] All references cited herein are incorporated herein in their entireties. If there is a conflict between a definition herein and in an incorporated reference, the definition herein shall control.
[0101] Referring to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 illustrates a row unit 10 of a conventional row planter. The row unit 10 includes a frame 12 supporting an opening disc assembly 20. The opening disc assembly 20 may include a pair of angled opening discs 22 (one of the opening discs 22 has been removed for clarity). The opening discs 22 are rollingly mounted to a downwardly extending shank 14 of the frame 12 and disposed to open a v- shaped seed trench 30 in a soil surface 32 as the row unit advances in a forward direction of travel through a field as indicated by arrow 34. A frog, or shank extension, 15 may be connected to shank 14. The row unit 10 may include a gauge wheel assembly 40 comprising a pair of gauge wheels 42 each pivotally mounted to one side of the frame 12 by a respective gauge wheel arm 44 (one of the pair of gauge wheels 42 and its gauge wheel arm 44 is removed for clarity). As is conventional, a depth adjustment assembly (not shown) may be provided to contact the gauge wheel arms 44 to limit the upward travel of the gauge wheel arms 44 with respect to the opening discs 22, thus limiting the depth of the seed trench 30 opened by the opening disc assembly 20. Also as is convention, the row unit 10 may support a seed meter (not shown) and a seed hopper (not shown). In operation, seeds 50 are communicated from the seed hopper to the seed meter. The seed meter singulates the seeds 50 and discharges the singulated seeds into a seed tube 52 supported by the frame 14. Rather than a seed tube, a seed conveyor (not shown) may receive the seeds discharged by the seed meter. The seed meter may be a vacuum-type meter such as that disclosed in International Patent Publication No. WO2012 / 129442. The seed tube 52 (or seed conveyor) directs the seeds 50 downwardly and rearwardly toward the seed trench 30. The seeds 50 are released the discharge end of the seed tube 52 (or seed conveyor) and are deposited in the open seed trench 30. A closing assembly 60 may 2021275615 13 Aug 2026 be pivotally coupled to the frame 14 and configured to “close” the seed trench 30 by move soil back into the open seed trench 30 over the deposited seeds.
[0102] Continuing to refer to FIG. 1, the row unit 10 includes a mounting bracket 100 which supports a seed firmer 70. An example of a mounting bracket 100 is Part No. 150111 available from Precision Planting LLC, 23207 Townline Road, Tremont, IL 61568. Examples of a seed firmers include the Keeton® seed firmer and the SmartFirmer™ , also available from Precision Planting LLC.
[0103] FIG. 2 is an enlarged perspective view of the mounting bracket 100 shown in FIG. 1. The mounting bracket 100 includes left and right mating halves 102, 104 as best seen in the exploded view of FIG. 2A. Each half 102, 104 includes a respective sidewall 106, 108 which extends forwardly. The forward end of each sidewall 106, 108 includes a mounting ear 110 and a hook member 112. The mounting ear 110 is sized to receive a pin 16 (FIG. 1) extending from each side of the shank 14 of the frame 12. The hook member 112 also engages with a pin 18 (FIG. 1) on the shank 18. It should be appreciated that the engagement of the mounting ear 110 and hook member 112 with the respective pins 16, 18 on the shank 14 rigidly secure the mounting bracket 100 with respect to the shank 14. The rearward ends of each half 102, 104 are secured together by pegs 114 received within matingly aligned apertures 116. As shown in FIGs. 2 and 2A, each half 102, 104 also includes inwardly projecting, longitudinally spaced forward and rearward flanges 118, 120 which matingly align, such that when assembled, the mating flanges 118, 120 define a through-opening 122 (FIG. 2) for receiving the upper portion of the firmer 70 as best illustrated in FIG. 3. Each of the rearward flanges 120 includes a slotted portion 124, which together define a transverse slot 126 when the halves 102, 104 are assembled. As discussed later, the transverse slot 126 receives the rearwardly projecting tab 80 of the resilient arm 78 of the seed firmer 70 while the bottom end of the forward flange 118 engages with the forwardly extending lip 82 on the firmer 70. The inwardly projecting flanges 118, 120 also serve as spacers between the sidewalls 106, 108 for receiving the seed tube 52 (or seed conveyor) therebetween as shown in FIG. 1. Thus the sidewalls 106, 108 surround the seed tube 52 (or seed conveyor) permitting independent movement of the seed tube 52 (or seed conveyor) with respect to the mounting bracket 100.
