Description

[Detailed description of the invention] The present invention provides a binding machine in which both the knotting part and the needle part are provided on the same side of the grain culm collecting part to make the whole binding machine smaller. The purpose is to improve the release of the culm.

However, the above-mentioned types of binding machines, such as the previously proposed binding machine shown in FIG. As a result, the binding cord or door hung on the discharge side of the collecting culm is pushed toward the discharge side every time the pack car scrapes, resulting in the collected culm becoming uneven or escaping to the discharge side. .

In the present invention, a knot part and a needle part are provided on one side of the grain culm collecting part, and a guide rod facing the bundle release direction is rotatable at a part of the knot part and needle part of the grain culm collecting part facing the transmission case. The guide rod is pivotally attached, and the middle part of the guide rod on the discharge side is bent from the pivot point toward the transmission case of the nodule part, so that one side of the grain convergence part is connected to the transmission case, and the other side is bent by the guide rod. On the upper side of the bundle and on the lower side, the discharge path is surrounded by a bent part that crosses the bundle while facing the bundle car, and the guide rod is configured so that when the bundle is discharged, the guide rod moves back largely around the pivot part and opens. By using the guide rod to catch the part of the grain culm that the packer has raked into the bundling part and to which the binding string is hung, the culm will not leak or become irregular, and will be bundled in an orderly manner. In addition, the above-mentioned problem is solved by preventing the guide rod from retreating from the discharge path and causing a discharge obstruction when the bundle is discharged.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. Reference numeral 1 denotes a transmission case provided on one side of the grain concentrating section 2, and a building 4a, on the side of the grain supply section 3.
A knot part 4 consisting of a holder 4b is provided,
A pair of needles 7, 7, a door 8, and a sensing lever 9 are attached to a needle shaft 6 provided on the discharge section 5 side.

Reference numeral 10 denotes a star foil provided on the nodule section 4 side of the grain culm supply section 3, and is intermittently rotated by one pitch each time the packer 11 scrapes once.

Reference numeral 12 denotes a guide rod whose base is rotatably supported on a fulcrum pin 13 to close the discharge section 5 during focusing, and is constituted by an elastic rod. It is attached to a frame 14 provided on the side facing the nodule part 4, and the base side of the guide rod 12 is formed into a curved part 12a that once protrudes toward the grain culm supply part 3 side and then curves outward. The spring 1 is connected near the base of this curved portion 12a.
5 so that the discharge side of the guide rod 12 closes the discharge part 5, and bends it toward the knot part 4 side at the middle of the rear part of the fulcrum pin 13 to close the other side frame of the binding part 4. and a receiving part that crosses the discharge part 5 while facing the packer 11.

In the drawing, 16 is a guide ring for the binding string, 17 is a cutter attached to the rear of the threshing device 18 of the combine harvester, and 19 is a guide rod.

In the above-mentioned device, the grain culms (or waste straw when this bundling machine is applied to a combine harvester) fed by the intermittent rotation of the star wheel 10 are sent to the grain culm convergence section surrounded by the door 8 and the guide rod 12 by the packer 11. 2, the collected culm is pushed down against the bullet 20, and the one-turn clutch is engaged. Stop, rotate 90 degrees counterclockwise in the figure to wrap the binding string around the bundled grain culms and feed it to the holder 4b, then turn clockwise.
When rotating by 270 degrees, the building 4a releases the knotted bundle in the direction of arrow A while releasing it.

At this time, the guide rod 12 rotates against the spring 15 as shown in FIGS. 4 and 5 to guide the grain culm bundle so that it is not pressed against the frame 14, and the curved portion 12a rotates for release. To prevent grain culms from being caught or pressed during rotation or return rotation.

As mentioned above, the present invention provides a knot part and a needle part on one side of the grain culm collecting part, and a part of the knot part and the needle part of the grain culm collecting part facing the transmission case,
A guide rod facing the direction of bundle release is rotatably mounted, and the middle part of the guide rod on the release side from the pivot point is bent toward the transmission case of the nodule part, so that one side of the grain convergence part is In the transmission case, the other side is surrounded by the bent part above the bent part of the guide rod, and the lower side is surrounded by the bent part that crosses the discharge path while facing the pack car, and when the bundle is released, the guide rod is centered around the pivot point. Since it is configured so that it can be opened by moving back greatly, unlike conventional binding machines, the transmission case does not extend from the needle part on one side of the converging part to the knot part on the other side, making the entire binding machine smaller and lighter. While the packer is operating to focus the culm, the guide rod constitutes one side frame of the grain culm focusing part at a portion opposite to the working locus of the packer, and also serves as a discharge path. By closing the culm, it is possible to catch the culm that is pulled in and focused, and prevent it from protruding outward and into the release path.As a result, even if the focusing culm is pressed multiple times by the packer, the focusing posture will not be disturbed, It does not fall out, and the part where the needle wraps the binding cord is made small to improve bundle tightening, and when releasing the bundle, the guide rod rotates around the end of the release path and retreats. The discharge path can be largely opened, the bundle can be guided in a state that does not become an obstacle to bundle discharge, and the bundle can be reliably discharged while preventing the culm from getting caught.
