Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a stem culm used for binding waste straw of a threshing device mounted on a combine harvester or a harvester, or for binding harvested husk culm in a binder, etc. Relating to a binding device.

[Conventional technology]

Conventionally, for example, in a waste straw binding device of a threshing machine, waste straw is continuously fed into a binding space from the conveyance end of a feed chain, a certain amount of waste straw is collected in the binding space, and the waste straw is collected at the waste straw exit of the binding space. A stem culm receiver placed on the downstream side in the direction of feeding the waste straw detects the above-mentioned certain amount of stem culm convergence pressure and activates the bundling device, or
- Like the binder proposed in Publication No. 18307, it has a rotation locus that overlaps with the binding space, and moves the stem culm to the binding space as it bundles, and also moves the binding device by rotating as it bundles. The activation body was placed at the entrance of the binding space.

[Problem that the invention seeks to solve]

In the former technique, since the stem culms are continuously fed into the binding space without interruption, it is difficult to separate the entangled stem culms, and in addition, the appropriate amount of stem culms is collected and the binding operation is started. Despite this, as the stem culms were sent in one after another, the next stem culm could become newly entwined with the tied stem culm, and the chestnuts were not tied and released. .

Moreover, in this conventional configuration, the knotting section mechanism, string supply section mechanism, discharge mechanism, focusing amount detection mechanism, etc. are arranged together in a limited space on both sides of the binding space, so each of these mechanisms The drive and interlocking of the two had become complicated.

In addition, in the conventional latter technique, although the binding space and the focusing space are separated in form by the actuating body having a rotation locus that overlaps with the binding space, in reality, as the binding space and the focusing space rotate, the two spaces Since the culms are mixed together and the inconvenience caused by the entangled culms cannot be avoided, it was necessary to provide a partitioning device for the culms further in front of the operating body in the culm feeding direction.

Other drawbacks are similar to the former technique.

[Means for solving problems]

The tying device of the present invention is a tying device in which a knotting mechanism and a string supply unit mechanism are arranged on both sides of a tying space, and the tying device is a tying device in which a tying mechanism and a string supply unit mechanism are arranged on both sides of a tying space. It receives and focuses, detects that a certain amount of stem culms have been focused, rotates at a position outside the binding space, and sends out a certain amount of focused stem culms toward the binding space as it rotates. In addition, a stem culm receiver is arranged to activate the binding device based on the detection.

[Effect]

In the above means of the present invention, the stem culms are bundled by the stem culm receiver in front of the bundling space.

When a certain amount of stem culms are bundled, the stem culm receiver rotates at a position outside of the binding space, and the bundled certain amount of stem culms is sent into the binding space as a unit and bundled. Ru.

〔Effect of the invention〕

■ The stem culm holder is arranged so as to rotate at a position away from the binding space, and a certain distance is created between the binding space and the focusing space, so that the stem culm retainer There is no room for the particles to get tangled, and it is possible to bundle each quantity very well without using a special partitioning device like the latter bundling device of the prior art.

◎ Compared to conventional binding devices, it is easier to arrange and configure desired mechanisms in the binding space.

That is, since the stem culm receiver is arranged at a position relatively distant from the binding space, there is ample space for this, and it is easy to arrange and configure desired mechanisms to be arranged on both sides of the binding space.

〔Example〕

The figure shows the rear part of the threshing device 1, and a binding device 3 is connected to the threshing device 3 in order to bind the waste straw W that has been threshed while being pinched and conveyed by the feed chain 2.

In the tying device 3, a tying mechanism 5 consisting of a tying building 4, etc., and a string supplying mechanism 7 consisting of a needle 6, etc. are arranged on both sides of the tying space B, and on the side where the tying mechanism 5 is arranged, A discharge arm 9 is provided which has the function of receiving the waste straw W fed into the puckering and bundling space B and the function of releasing the bundled waste straw W.

Then, the end of the feed chain 2 and the guide 13
A path S is formed through which the waste straw W discharged from the threshing device 2 is sent to the bundling space B, and
In this path S, that is, in the upper part of the path for feeding the waste straw from the bundling space B, a converging part 10 for the waste straw W is provided.

The concentrating section 10 is configured by a catch 11 disposed in an upright position perpendicular to the direction of the feed path S, and is configured to receive and condense the waste straw W sent along the feed path S. In addition, the receiver stopper 11 is configured to have a detection function in the focusing portion 10 as a mechanism for detecting the amount of collected waste straw W, and further, this It is configured to have a feeding and conveying function as a conveying mechanism that rotates based on the movement of the waste straw W and feeds the collected waste straw W to the bundling space B side.

Further, the detection result of the stopper 11 is transmitted to the needle 6 and the knot building 4 via a desired mechanism, that is, the receiver transmits the detection result of the stopper 11 to the knotting mechanism 5 and the string supply mechanism. 7.

In the figure, reference numeral 12 denotes a packer that scoops the waste straw W discharged from the threshing device 2 into the concentration section 10.

Further, the scraping packer 8 is completely the same as the conventional one except that it is provided on the knotting mechanism 5 side, and is constantly driven by a well-known drive structure.

Further, the release arm 9 has the same structure as the conventional one, and as a result of the well-known structure, it is a binding mechanism that is intermittently driven when a clutch (not shown) is engaged and operated based on the detection operation of a catch 11, which will be described later. It is attached to the main gear 14 of No. 5 and operates intermittently during the binding operation.

According to the above configuration, the waste straw W discharged from the threshing device 1 is bundled as described below.

That is, the waste straw W is collected at the converging part 1 in the middle of the feeding path S.
0, after the receiver is bundled by an appropriate amount, based on the detection of the amount of convergence by the stopper 11, the receiver is fed and conveyed to the binding space B side by the rotating operation of the stopper 11, and in the binding space B, the receiver is fed to the string supplying mechanism 7. In cooperation with the knotting mechanism 5, they are tied together and released by the release arm 9, and the process is repeated in the same manner.

In the embodiment, the binding device 3 connected to the rear part of the threshing device 1 is shown, but it goes without saying that this can also be applied to a harvested stem culm binding device in a binder or the like.
