Dog for an ejector system of a square baler
View Patent ↗A dog is disclosed for mounting on a shuttle assembly of a bale ejector system of a square baler. The dog has two pointed ends and at least one mounting feature that permits the dog to be pivotably mounted on the shuttle assembly. The dog is symmetrical so as to be selectively capable of being mounted on the shuttle assembly in each of two orientations in order to extend the service life of the dog.
1. A dog for mounting on a shuttle assembly of a bale ejector system of a square baler, the dog comprising:
a body having two pointed ends;
at least one mounting feature with two pivotal connection points on the body wherein the body is configured for pivotal mounting around a pivot point on the shuttle assembly, wherein the body is symmetrical with respect to a center of gravity of the body such that the body is configured to be selectively mounted on the shuttle assembly in at least two orientations wherein in a first orientation a first pointed end of the two pointed ends is located above a second pointed end of the two pointed ends and and configured to engaged in the bale formed in the bale case of the square baler and in a second orientation the second pointed end of the two pointed ends is oriented above the first pointed end, and configured to engage in the bale formed in the bale case of the square baler.
2. A dog as claimed in claim 1 , wherein the at least one mounting feature comprises two mounting features disposed on opposing sides of the centre of gravity of the body.
3. A dog assembly comprising,
a body having two pointed ends for engaging a bale;
at least one mounting feature with two pivotal connection points on the body configured for pivotally mounting the body to a shuttle assembly around a pivot point on the shuttle assembly, wherein the body is symmetrical with respect to a center of gravity of the body;
the at least one mounting feature configured to selectively mount the body to the shuttle assembly at one of the two pivotal connection points on the body; and
abutment surfaces that define the limits of rotation of the body in both directions wherein the abutment surfaces are positioned on the same side of the dog.
4. A dog as claimed in claim 3 , wherein the abutment surfaces are formed from a stop having a portion that extends from a position above the pivot point of the dog to a position below the pivot point of the dog.
5. A dog as claimed in claim 1 , wherein the dog is mounted to a bar of the shuttle assembly such that it is biased into the extended position as to grip into the bale when the shuttle assembly is moved towards a discharge outlet of the square baler.
6. A dog for mounting on a shuttle assembly of a bale ejector system of a square baler, the dog comprising:
a body having a first pointed end, a second pointed end;
at least one mounting feature with two pivotal connection points on the body configured for pivotal mounting around a pivot point on the shuttle assembly at one of the two pivotal connection points on the body whereby the body when pivoted to a first position is positioned to engage in a bale formed in a bale case of the square baler, wherein a first bale contacting portion at the first pointed end of the body located above the at least one mounting feature is symmetrical with respect to a center of gravity of the body to a second bale contact portion at the second pointed end of the body below the at least one mounting feature and that body is shaped and configured for being mounted on the shuttle assembly in at least two orientations.
