Abstract
A knotter for a baler, the knotter including a knotting system with at least one movable part, and a driver, operatively connected to the at least one movable part. The knotter is further provided with a first cover, associated with at least one movable part, having a first covering position wherein the first cover at least partly covers the at least one movable part, and a second uncovering position, wherein the first cover no longer covers the at least one movable part. The knotter further includes a safety mechanism, operatively connected to the driver and the first cover, such that positioning or enabling the positioning of the first cover in the second uncovering position stops the moving of the at least one movable part.
Claims17
A knotter for an agricultural baler, comprising:
- a knotting system with a frame and first and second movable parts adapted for moving while binding a bale;
- a driver operatively connected to the first and second movable parts for arranging a movement of the first and second movable parts;
- a first cover pivotably connected to the frame and associated with the first movable part, the first cover having a covering position wherein the first cover at least partly covers the first movable part, and an uncovering position wherein the first cover no longer covers the first movable part;
- a second cover pivotably connected to the frame, associated with the second movable part and having a covering position wherein the second cover at least partly covers the second movable part, and an uncovering position wherein the second cover no longer covers the second movable part;
- and
- a safety mechanism operatively connected to the driver, the first cover and the second cover by a lever, such that a positioning of the lever stops movement of the first movable part and the second movable part;
- wherein the second cover is positioned opposite to the first cover relative to the lever and is positioned in the second cover uncovering position only after the first cover is positioned in the first cover uncovering position.

A baler, comprising:
- a bale-forming chamber and a knotter operatively connected to the bale-forming chamber;
- the knotter comprising:
- a frame;
- first and second movable parts adapted for moving while binding a bale;
- a driver operatively connected to the first and second movable parts for arranging movement of the first and second movable parts;
- a first cover pivotably connected to the frame and associated with the first movable part, the first cover having a covering position wherein the first cover at least partly covers the first movable part, and an uncovering position, wherein the first cover no longer covers the first movable part;
- a second cover pivotably connected to the frame, associated with the second movable part and having a covering position wherein the second cover at least partly covers the second movable part, and an uncovering position wherein the second cover no longer covers the second movable part;
- and
- a safety mechanism operatively connected to the driver, the first cover and the second cover by a lever, such that a positioning of the lever stops movement of the first movable part and the second movable part;
- wherein the second cover is positioned opposite to the first cover relative to the lever and is positioned in the second cover uncovering position only after the first cover is positioned in the first cover uncovering position.

A baler, comprising:
- a bale-forming chamber and a knotter operatively connected to the bale-forming chamber;
- the knotter comprising:
- at least one movable part adapted for moving while binding a bale;
- a first cover associated with the at least one movable part, the first cover having a covering position wherein the first cover at least partly covers the at least one movable part, and an uncovering position wherein the first cover no longer covers the at least one movable part;
- a handle associated with the first cover, the handle being configured to be positioned in a first position in which the first cover is locked in the covering position and a second position in which the first cover is enabled to be positioned in the uncovering position;
- a lever operatively connected to the handle;
- a stopper bar operatively connected to the lever;
- and
- a mechanical trip mechanism;
- wherein actuation of the handle into the second position actuates movement of the lever;
- wherein a protrusion on the first cover is configured to engage an arm of the handle when the handle is positioned in the first position;
- wherein movement of the lever during actuation of the handle into the second position rotates the stopper bar to engage with and lock the mechanical trip mechanism;
- and
- wherein locking of the mechanical trip mechanism prevents movement of the at least one movable part.
