Abstract
A seed delivery system housing contains a transport mechanism for moving seed along a seed path through the delivery system housing. A wear liner may include a wear liner insert extending along a portion of the seed path within the delivery, the wear liner insert including a wear surface interposed between the transport mechanism and the seed delivery system housing to protect at least one of the seed and the seed delivery system housing from wear. In certain embodiments, various features of the liner may extend outside the seed delivery system housing, to further protect the housing.
Claims14
A wear liner for a seed delivery system housing, the seed delivery system housing containing, at least in part, a belt transport mechanism for moving seed along a seed path through the seed delivery system housing, the wear liner comprising:
- a wear liner insert extending along a portion of the seed path within the seed delivery system housing, the wear liner insert including a wear surface interposed between the belt transport mechanism and the seed delivery system housing to protect at least one of the seed and the seed delivery system housing from wear;
- wherein the wear liner insert includes a plurality of distinct insert sections including an upper insert section, and at least one of a middle insert section and a lower insert section disposed on opposite sides, with respect to the seed path, of a sensing unit of a seed sensor for seed traveling along the seed path.
A wear liner for a seed delivery system housing, the seed delivery system housing containing, at least in part, a belt transport mechanism for moving seed along a seed path through the seed delivery system housing, the wear liner comprising:
- a wear liner insert extending along a portion of the seed path within the seed delivery system housing, the wear liner insert including a wear surface interposed between the belt transport mechanism and the seed delivery system housing to protect at least one of the seed and the seed delivery system housing from wear;
- wherein the wear liner insert includes a plurality of distinct insert sections including at least two of an upper insert section, a middle insert section, and a lower insert section;
- and
- wherein a downstream end, with respect to the seed path, of one of the upper insert section and the middle insert section extends away from the seed delivery system housing toward the seed path to provide a first clearance between the wear liner insert and the belt transport mechanism;
- and
- wherein an upstream end, with respect to the seed path, of one of the middle insert section and the lower insert section, respectively, extends away from the seed delivery system housing toward the seed path to provide a second clearance between the wear liner insert and the belt transport mechanism, the upstream end being adjacent to the downstream end and the first clearance being smaller than the second clearance.
A wear liner for a seed delivery system housing, the seed delivery system housing being located adjacent to one or more furrow opening disks and containing, at least in part, a transport mechanism for moving seed along a seed path through the seed delivery system housing, the wear liner comprising:
- a mounting portion secured to the seed delivery system housing;
- and
- one or more external liner portions extending outside the seed delivery system housing and away from the mounting portion to protect the seed delivery system housing from the one or more furrow opening disks.
