Description

CLOSING SYSTEM ALIGNMENTCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 63 / 619827, filed 11 January 2024, which is incorporated herein by reference in its entirety.FIELD

[0002] Embodiments of the present disclosure relate generally to planter row units.BACKGROUND

[0003] Planter row units can have a closing system to close a trench opened by an opening system on the planter row unit. It is desirable for the closing system to align with the opening system.BRIEF SUMMARY

[0004] In an aspect of the invention there is provided a planter row unit comprising: a frame; an opening system for opening a trench disposed on the frame; a gauge wheel system for adjusting the depth of the opening system, wherein the gauge wheel system comprises a first gauge wheel arm, a first gauge wheel connected to the first gauge wheel arm, a second gauge wheel arm, and a second gauge wheel connected to the second gauge wheel arm; a closing system connected to the frame through a connection bracket, wherein the connection bracket comprises a first bolt disposed closer to the opening system than a second bolt, and a nut with an eccentric disposed about the second bolt for adjusting a relative position of the closing system with the opening system.

[0005] Within the scope of this application it should be understood that the various aspects, embodiments, examples and alternatives set out herein, and individual features thereof may be taken independently or in any possible and compatible combination. Where features are described with reference to a single aspect or embodiment, it should be understood that such features are applicable to all aspects and embodiments unless otherwise stated or where such features are incompatible.BRIEF DESCRIPTION OF THE DRAWINGS

[0006] One or more embodiments of the invention / disclosure will now be described, by way of example only, with reference to the accompanying drawings, in which:

[0007] FIG. 1 is a perspective view of a planter row unit.

[0008] FIG. 2 is a right side elevation view of the planter row unit of FIG. 1.

[0009] FIG. 3 is a perspective view of a portion of the planter row unit of FIG. 1 showing the row unit frame and closing system.

[0010] FIG. 4 is a perspective view of a connection bracket of the closing system of FIG. 1.

[0011] FIG. 5 is a perspective view of a nut with eccentric of the closing system of FIG. 1.

[0012] FIG. 6 is a bottom perspective view of the nut with eccentric of FIG. 5.

[0013] FIG. 7 is a bottom plan view of the nut with eccentric of FIG. 5.DETAILED DESCRIPTION

[0014] All references cited herein are incorporated herein in their entireties. If there is a conflict between definitions herein and in an incorporated reference, the definition herein shall control.

[0015] FIGs. 1-2 illustrate a planter row unit 100. Planter row unit 100 has a frame 110 having gauge wheel system 170 with first gauge wheel 171-1, second gauge wheel 171-2, first gauge wheel arm 172-1, and second gauge wheel arm 172-2. Frame 110 also has opening system 160 having first opening disc 161-1 and second opening disc 161-2. Planter unit can have a hopper 140 and seed meter 150 for depositing seeds into a trench opened by opening system 160. Planter row unit 100 can have linkage 120 for connecting to a toolbar (not shown). Optionally, a downforce system 130, such as the one described in US9879702B2, can be connected to linkage 120.

[0016] A closing system 250 is connected to frame 110. An example of closing system 250 is described in US2020 / 0396894A1, and in particular, embodiment 250D.

[0017] FIGs. 4-7 illustrate a modified connection bracket 1540 as was described in US2020 / 0396894A1. Connection bracket 1540 has first bolt 1540 and second bolt 1542 for connecting connection bracket 1540 to frame 110. Second bolt 1542 has a nut 1543 with eccentric 1544. Nut 1543 with eccentric 1544 can be adjusted to change the relative position of connection bracket 1540 with frame 110 before second bolt 1542 and first bolt 1540 are secured. This adjusts the relative position of closing system 250 to opening system 160 to align closing system 250 and opening system 160.

Claims

CLAIMSWhat is claimed is:

1. A planter row unit comprising: a frame; an opening system for opening a trench disposed on the frame; a gauge wheel system for adjusting the depth of the opening system, wherein the gauge wheel system comprises a first gauge wheel arm, a first gauge wheel connected to the first gauge wheel arm, a second gauge wheel arm, and a second gauge wheel connected to the second gauge wheel arm; a closing system connected to the frame through a connection bracket, wherein the connection bracket comprises a first bolt disposed closer to the opening system than a second bolt, and a nut with an eccentric disposed about the second bolt for adjusting a relative position of the closing system with the opening system.
