Abstract

(57) [Summary] [Purpose] The object is to provide a tying machine for a combine harvester that can properly tighten bundles. [Structure] A tying machine has a door on the bundle release side of a converging section with a needle at the bottom and a knotting section at the top, including a needle standby position, the most protruding position of the needle, and a first point for hanging the tying string. The position of the protrusion and the position of the door are determined by the distance from the string locking part of the needle tip in the standby position to the contact point of the virtual bundle to the bottom plate, which is pulled in by the packer while the string is hooked to the front of the door, and the position of the door. A binding machine for a combine harvester in which the distance from the contact point through the first protrusion to the locking part at the most protruding position of the needle is approximately equal.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a tying machine for a combine harvester that collects and ties waste straw.

0002

[Conventional technology]

Conventionally, the needle was placed at the bottom of the bottom plate, the knot part was placed above, and the focusing part was placed between them. When the door installed on the emission side of the convergence section is sensed and activated, the needle is hooked on the string. A tying machine for a combine harvester is already known, in which the knotting section is activated to tie the knot. It is.

0003

[Problem that the invention attempts to solve]

Conventionally, in a binding machine, the door senses and operates and the needle is tied. The needle at the most protruding position from the point where the virtual bundle touches the bottom plate through the first protrusion Distance A to the string locking part at the tip and the string lock at the standby position of the needle from the above contact point There was a difference in distance B to the stop, so if distance B is longer than A, the bundle will not be tight. Also, if it was too short, the string could break and result in tying errors.

0004

[Means to solve the problem]

The present invention has a focusing part 3 which has a needle 10 in the lower part and a knot part 7 in the upper part. In a binding machine equipped with a door 9 on the bundle release side, the needle standby position and the needle most The extended position, the position of the first protrusion 16 on which the binding cord is hung, and the position of the door 9 are set to the standby position. Attach the string to the front of the door 9 from the string locking part at the tip of the needle at A, and attach it to the packer. The distance from the contact point B of the virtual bundle 17 to the bottom plate 2 and the first The distance from the protrusion 16 to the locking part at the most protruding position of the needle should be approximately equal. The above-mentioned problem was solved by making the bundle tighter and preventing the string from breaking.

[0005]

[Effect]

The packer rakes the straw discharged from the combine threshing equipment into the front of the door. When the amount of convergence reaches a predetermined amount and the door is sensed and activated, the one-turn clutch engages. After the needle is hooked and the knot is activated, the release arm is activated to remove the knot. Pull it out and release the bundle. Then, the needle rotates from the standby position to the most protruding position and winds. When the hook is activated, the length of the string that is wound through the first protrusion is such that the virtual bundle touches the bottom plate. The distance between the point and the string locking part of the needle tip in the standby position is approximately equal. Therefore, the part where the string is in contact with the string locking part of the needle hardly changes, and the string is wrapped around the focused culm while maintaining the tension set by the string brake. It will be done.

[0006]

【Example】

To explain the present invention in more detail with respect to the embodiment shown in the drawings, the combine harvester is shown in the drawings. Although not shown, like the conventional model, there is a self-thresher type threshing machine on one side of the machine with a traveling device. The equipment is mounted on the other side, and an operation panel, a driver's seat, and a grain tank are arranged on the other side. A binding device 1 is attached to the rear of the grain device directly or via a desk-type cutter. be.

[0007] The bundling device 1 has a bottom plate 2 at the bottom, and above the bottom plate 2, a knot gait is arranged with a convergence part 3 in between. A node 7 and a release arm 8 consisting of an id 4, a building 5, and a holder 6 are provided to release the bundle. A door 9 is provided on the exit side, and a needle 10 and a constantly rotating shaft are provided at the bottom of the bottom plate 2. 11, the tip of the crank arm 12 rotates in a horizontally long elliptical trajectory. A packer 13 is provided.

[0008] Then, the waste straw discharged from the threshing device is sent to the front of the door 9 by the packer 13. It is engaged intermittently, and when the amount of convergence reaches a predetermined amount, the one-turn clutch is engaged and the state shown in Fig. 2 is applied. Then, the needle 10 crosses the scraping path from the standby position A and attaches the string 15 to the holder 6. Advance to the most protruding position to sandwich it. At this time, the string that was running on the bottom plate 2 15 is a first tube protruding from the nodule guide 4 along the bundled straw in an arc shape. After being caught on the protrusion 16, it is caught in the holder 6, and the building 5 and holder 6 are activated. After that, the discharge arm 14 discharges the bundle.

[0009] When the needle operates to hook a string, a U-groove is installed at the tip of the needle 10 in the standby position. It extended from the string locking part 18 consisting of a girder pin to the contact point B of the virtual bundle 17 to the bottom plate 2. From point C where the string hangs on the first protrusion 16 as the needle 10 rotates to the most protruding point of the needle However, the length of the string 15 from the contact point B to the most protruding point D is The length of the string extending to the standby position A and approximately the needle 10 are pulled to hang on the focusing culm. It is set by the string brake when the needle 10 advances without being released. The tension will cause the string to be pulled out, and the string may end up being too loose for the bundle, or It can be applied with the appropriate tension without being too strong, and the needle 10 is in the standby position. When the packer 6 returns to position A and rakes in the waste straw, it returns to the illustrated state. Also, released The collected straw bundles are carried diagonally by a bundle clamping and conveying device consisting of a conveying chain 19 and a clamping culm 20. It is transported and released to the mowed area behind the farm.

[Effect of the idea]

The present invention has a focusing part 3 which has a needle 10 in the lower part and a knot part 7 in the upper part. In a binding machine equipped with a door 9 on the bundle release side, the needle standby position and the needle most The extended position, the position of the first protrusion 16 on which the binding cord is hung, and the position of the door 9 are set to the standby position. Attach the packer 1 with the string attached to the front of the door 9 from the string locking part 18 at the tip of the needle. 3, the distance from the virtual bundle 17 to the contact point B on the bottom plate 2, and the contact point B. The distance from the first protrusion 16 to the string locking part 18 at the needle most protruding position is approximately equal As a result, the bundle becomes less tight, or the tension on the string becomes too strong, causing it to break. To reliably prevent bundling mistakes while always tying to the appropriate strength without causing any damage. Can be done.
