Estimating the term…
Sweep retaining structure includes a spring wire retainer with a base supported in a groove on the underside of the wedge support which mates with a stem portion of the sweep. The wedge support is apertured, and a central curved portion of the retainer passes through the aperture and supports a sweep-contacting end above the surface of the wedge support. The end is biased toward a contact area on the sweep to engage the area and eliminate sweep loss problems by preventing the sweep from slipping downwardly from the mounted position. To remove the sweep, a tool is inserted through the slot to depress the retainer end, and the sweep is forced off the wedge support. A raised area on the sweep directs soil away from the retainer and contact area to reduce wear and eliminate depression of the end during operation. The underside of the raised area positions the wire end and provides bend-resisting support for the wire.
A knock-on sweep assembly for a tillage implement sweep having a forward cutting edge, the assembly including a sweep support, a sweep mounting portion located rearwardly of the cutting edge and mating with the sweep support, the sweep mounting portion providing a fastenerless tight but releasable fit when the sweep is in a mounted position on the sweep support, and retaining structure for preventing the sweep from dislodging from the sweep support, the retaining structure including a contact area on the mounting portion, and a bent wire retainer supported by the sweep support and having an end, the end offset from the sweep support and biased into a locking position wherein the end abuts the contact area when the sweep is in the mounted position and prevents the sweep from moving away from the mounted position until the end is moved toward the sweep support against the bias.
A knock-on sweep assembly for mounting a tillage implement sweep with a forward soil entry portion including a cutting edge on shank structure, the assembly including a sweep support connected to the shank structure, a sweep mounting portion located rearwardly of the cutting edge and mating with the sweep support, the sweep mounting portion providing a fastenerless tight but releasable fit when the sweep is in a mounted position on the sweep support, and retaining structure for preventing the sweep from dislodging from the sweep support, the retaining structure including a contact area on the mounting portion, and a retainer supported by the sweep support and having an end, the end offset from the sweep support and biased into a locking position wherein the end abuts the contact area when the sweep is in the mounted position and prevents the sweep from moving away from the mounted position until the end is moved toward the sweep support against the bias, and wherein the sweep mounting portion includes a raised soil-deflecting portion located forwardly of the contact area on the mounting portion for directing soil and debris away from the contact area, the raised soil-deflecting portion defining a retainer receiving cavity providing support for the retainer when the end is in the locking position to thereby help the retainer resist bending forces.
