Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a binding machine that binds a plurality of straw bundles into a large bundle.

(b) Prior Art Conventionally, a tying machine for collecting several bundles of straw threshed by a harvester and tying them into a large bundle is already known from Japanese Patent Laid-Open No. 59-232023.

(c) Problems to be solved by the invention In the above-mentioned known tying machine, when the packer pulls the straw bundle into the bundle part and compresses it, the tying string (hereinafter referred to as the small bundle string) loosens as shown in Fig. 8. This sometimes enters the nodule side through the opening of the nodule guide and gets caught on the first protrusion, and in such cases, clogging occurs when the bundle is discharged or the first protrusion is damaged.

(d) Means for solving the problem The present invention focuses a plurality of straw bundles and supplies a string from the opening of the knot guide to the knot part using a needle.
In a tying machine that discharges knotted bundles with a discharge arm, the opening is diagonally crossed from the first protrusion of the knotting guide toward the bundle supply side, from the distal end side of the first protrusion toward the base side. By attaching an elastic guide and bending the tip of the elastic guide toward the tip of the first protrusion and making it follow the first protrusion 25, the binding string that comes up when the packer compresses the bundle can be removed. The above-mentioned problem was solved by guiding the elastic guide from the distal end side to the base side of the first protrusion.

(E) Function The supplied straw bundles are sequentially focused by the packer into the converging section, and when it reaches a predetermined amount, the one-turn clutch engages like the conventional one, and a string with a strong needle (hereinafter referred to as the large bundle string) is applied. When the knot is knotted, the large bundle string of the release arm comes off the first protrusion and the second
While hanging on the protrusion, it releases a large bundle while cutting out the knots.

When the bundle is compressed by the packer, the small bundle string loosens and enters the opening of the knot guide, but the elastic guide catches the small bundle string that is about to enter on the bundle supply side of the first protrusion. Since it is guided in a direction away from the first protrusion, the bulging small bundle string does not get caught on the first protrusion.

(F) Example An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a threshing machine mounted on a harvester stand 2, and on the end side of the feed chain 3 there is a support 6 on which a binding machine 5 is mounted on a guide rail 4a with rollers 4b, and a connecting rod 7 at the top. Similar to the conventional one, the tying machine 5 has a bundler 9 and a needle 10 at the bottom of the converging section 8, and a building 12a surrounded by a knot guide 11 and a holder 12b at the top. A door 15 is attached to the outer side of the converging section 8 so as to be movable forward and backward by means of a fitting 16, and the output shaft 17 of the thresher 1 is connected to a belt 18 and Input shaft 20 of binding machine 5 via tension pulley etc.
to drive.

Further, an arm 21 protruding from the nodule guide 11 toward the threshing machine 1 side, and an elastic guide plate 22 extending toward the upper part of the converging section 8 above the culm opening of the threshing machine 1;
The base of 23 is attached.

Furthermore, the tuberosity guide 11 has an opening 24, and the first protrusion 25 crosses the upper side of the second protrusion 26 from one side of the opening 24 to face the recess 27 on the other side. There is a bundle holding plate 30 on the discharge side.
It is screwed on.

As shown in FIGS. 5 and 6, the rod-shaped elastic guide 28 has its base portion near the bundle supplying portion of the tubercle guide 11 and on the opposite side of the attachment portion of the first protrusion 25 with a screw. The opening 24 is diagonally crossed toward the other side, and the tip is bent along the first protrusion 25 to form a receiving portion 28a.
It protrudes from the protrusion 25.

In the above-mentioned device, when a bundle of grain culms cut and tied with a binder etc. is fed to the threshing machine 1, the feed chain 3 and the pinching rail pinch and convey the grain culm, so that the bundle is threshed and discharged from the culm opening. The straw bundle is guided by the elastic guide plates 22 and 23 and pulled into the collecting section 8 by the packer 9. When a predetermined amount of straw bundle is collected and the door 15 is sensed and activated, a one-turn clutch engages and connects the needle shaft and the knot. The shaft rotates, and the needle 10 wraps the large bundle string 31 around the straw bundle group, enters the knot through the opening 24, and closes the holder 1.
2b, the building 12a and the holder 12b
is activated and nodule occurs.

Then, when the needle 10 wraps around the large bundle string 31 and enters the opening 24, the packer 9 compresses the straw bundle group, so that the small straw bundle string 32 bulges out in a bifold shape and enters the opening 24. It enters, but the first protrusion 2
A receiving portion 28 of the elastic guide 28 is provided on the upper side of the elastic guide 5.
A receives the swollen small bundle string 32 as shown by A in FIG. As shown, it is only deformed but not caught by the first protrusion 25.

Further, as shown in FIG. 7, the large bundle of string supplied to the holder 12b by the needle 10 deforms the elastic guide 28 as shown by the chain line, slides through the C position, moves to the D position, and hangs on the first protrusion 25. , the building 12a rotates and pulls the string as described above, and the large bundle of strings 31 comes off the first protrusion 25 and moves to the second protrusion 2.
6, the discharge arm 13 discharges the bundle while cutting.

(g) Effects of the invention This invention focuses multiple straw bundles to create a needle 10
In a tying machine in which a string is supplied from the opening 24 of the knot guide 11 to the knot part and the knotted bundle is discharged by the discharge arm 13, from the first protrusion 25 of the knot guide 11 to the bundle supply side, The opening 2 extends from the tip side of the first protrusion 25 toward the base side.
An elastic guide 28 that diagonally crosses the first protrusion 25 is attached, and the tip of the elastic guide 28 is bent toward the tip of the first protrusion 25 so that it runs along the first protrusion 25. Even if the small bundle string 32 is compressed and loosens and enters the opening of the knot guide 11, the elastic guide 28 receives it and moves from the tip side of the first protrusion to the base side as it is scraped by the packer. As a result, the small bundle string 32 is not caught on the first protrusion 25, and clogging or damage to the first protrusion 25, which is conventional, is reliably prevented. be able to.
